Why are pigs in Africa struggling to meet the growth rates achieved in Europe?
Why do pigs in Africa sometimes struggle to reach 100kg in five months? And does this matter to the profitability of your farm?

Historically, slaughter weights achieved by sub-Saharan African wild pigs reared in Africa tend to be lower than the weights achieved by European breeds raised in Europe. What is perhaps surprising is that those same high-performing European breeds also do not perform as well in Africa as they do in Europe. Over the course of two articles, we explore why this performance gap is observed between pig herds in Africa and Europe and whether this has a critical impact on the profitability of pig farms in Africa.
To answer the first part of this question, we need to understand the innate behaviour and characteristics of domestic pig breeds and their wild pig ancestors. According to Lund and Weary, “natural behaviour is the collection of different behaviours that pig have acquired and used to survive the evolutionary process. These innate behaviours are essential aspects of natural and survival behaviour”.
To raise pigs successfully and profitably, we must tailor husbandry protocol to suit the innate needs of the pig and ensure the environment is optimised for their productivity.
Living environment
Temperature
Research has also shown that environment temperature is a significant factor affecting both voluntary feed intake level and overall nutrient requirements for pigs.
The preferred temperature range for pigs is called the thermoneutral zone. This is the range of temperature in which the pig is comfortable and does not require additional or reduced energy intake to maintain body temperature.
As a general rule, for every 2 °F decrease below or above the thermoneutral zone, energy intake in growing pigs will be increased or decreased, respectively, by about 40 kcal/da. In cold conditions like in Europe, the pig increases food consumption and energy metabolism to generate body heat and maintain internal body temperature. In contrast, when environmental temperatures are above the thermoneutral zone, like in Africa, pigs consume less feed to reduce the extra heat produced by digestion of feed and metabolism of nutrients.
In parts of Africa where the temperature is consistently above the thermoneutral zone, pigs automatically decreases the amount of feed they consume so as to reduce the extra heat generation thus resulting in poorer feed conversion and slower growth rate.

More fat and less lean meat
During the first four months in the life of a pig (under 45kg weight), the muscle tissue and the bones of the skeleton develop faster than the fat tissues. However, at four months old, this process is reversed, and muscle, which forms the lean meat, develops slower, and the pig body forms more fat.
For pigs raised in hotter climates, they may reach the 45kg weight at the same time as those raised in more temperate countries. However, as they reach 45kg and switch to producing more body fat, they begin to experience more heat stress and as a result, they automatically begin to consume more water and less feed.

The impact of warm weather on pig physiology was further confirmed in recent studies which show that even in temperate countries, breeding and carcase weights of pigs are lower in the summer months than during winter months.

Stocking density
It is easy for stocking density to get out of control as your pigs increase in size, but this problem is further exacerbated by the higher ambient temperature in Africa. Research has shown that in intensive systems, stocking densities should be lowered by 10 percent if the temperature is above 25 degrees Celsius.
Stress
Research has shown that environmental stress plays a significant part in the growth rate of pigs. Naturally, acute stress is a natural part of a pigs’ life and this starts from within the context of their social dynamics, especially during feeding and drinking and mating - within a few hours after birth, social dominance hierarchies are established among piglets.

Genetics
Most of the exotic breeds, imported to sub-Saharan Africa have been genetically engineered by scientists in their country of origin to reach certain weights within a particular time frame under some stipulated environmental conditions and parameters, which is sometimes difficult or too expensive to adhere to on the typical pig farm environment in sub-Saharan Africa. This includes the conducive weather, farm environment, housing, pathogen exposures, and staffing, all of which impact the performance and the growth rate of the pig.
As a pig farmer and trainer, people always ask me what breed of pig is the best for their system? My answer is that it depends on the goal of your farm and this is not always the answer that people expect from me. I always stress the importance of ‘profitability’ during my training because just increasing the litter size of pigs (or any other physical performance of the pigs) is not enough. You need to consider how profitable the whole effort is and will be.
I have met many African farmers who started their farm with high-performing exotic pig breeds in Africa without taking the time to understand the fundamentals of pig farming. The price of these imported pigs and the cost of feeding them (concentrate) was so expensive that with the current pig market situation and the price of feed, especially in Nigeria, it was extremely difficult for such pig farmer to break even despite all the praiseworthy effort and courageous capitalisation that they have invested on their farms.
I have also seen farms rearing hybrid pigs (a cross between an exotic breed and a popular local breed) which cost less than the pure exotic breeds and also require less capital to feed (because they can partly utilise locally available feed ingredients). Though these hybrids have performed below the high-performing exotic breeds in physical performance, they are more profitable when considering the return on investment and currrent market price of pigs.
Furthermore, while genetics play an important role in achieving success in pig farming, they only account for 30 percent of the factors determining pig growth rate. Farmers should focus on providing good husbandry and maintaining a high health status in their herd.
Birth and weaning weight
Research has shown that poor feeding during pregnancy, poor weaning weight/size due to poor creep feed, the age of weaning, quality of staff all impact pig’s growth rate. For example, a difference of 0.5 kg birthweight is equivalent to a weaning weight of 1 kg and 10kg at finisher weight. Birth weight is important because it is an area that is within the farmer’s control. Birthweight is not determined by genetics but rather by how well your staff manage and treat the gilt or sow at the very early stage of the reproductive cycle.
Feed
Ingredients and quality
Many African pig farms can only afford to provide pigs with industrial waste or by-products such as palm kernel cake, corn bran, wheat bran and some maize and soya meal. This is not because African farmers are cruel and mean to their pigs but rather because they cannot harvest enough grain to feed both the human population and the pig population.
Research has shown that many of these common feedstuffs used in Africa contain natural toxins or indigestible nutrient forms that actually impair pig performance and reduce voluntary feed intake, thus negatively affecting feed:conversion ratios. These toxins include phytate, trypsin inhibitors, saponins, tannins, and glucosinolates. Trypsin inhibitors are present in soybeans that have not been properly heat processed, and are also present in alfalfa, rye and barley.
Other factors affecting feed and ingredient quality in Africa include the lack of appropriate feed ingredients which is aggravated by persistent incidences of drought or floods. The production and the quality of feedstuffs is often low and seasonal. This situation is further exacerbated by poor harvesting, processing and storage of the feed ingredients, lack of laboratory facilities for chemical analysis of ingredients, lack of trained feed technologists, frequent interruptions in power supply to grind and compound feed ingredients, and lack of spare parts for maintenance of equipment for harvesting and processing, which are generally imported from other countries.

Mycotoxins
Mycotoxins are leftover toxic chemical products produced by organisms of fungal origin. Fungi include moulds, mildews, rusts, yeasts and mushrooms. As an organism, they lack chlorophyll, leaves, true stems and roots. They reproduce by growing spores on dead organic matter or parasites.
Mould is the coating or discolouration caused by various fungi that develop in a damp atmosphere on the surface of stored food - this is prevalent where humidity is very high during the rainy season especially in forested areas. The mould fungus may be harmless or even dead but it can still leave mycotoxin (poisonous) residues behind, commonly in stored and mixed feed, and especially in mouldy grain.
Even when the grain is eventually processed, while it may destroy the moulds, it still leaves mycotoxin residues behind. Mycotoxins only need to be present in very small quantities in the feed to cause problems in pigs, such as infertility, anoestrus, prolapse, false pregnancies and embryo mortality. Poor growth and vomiting are also common clinical signs of mycotoxin poisoning. Mycotoxins can also pass through sow’s milk and remain behind in any slaughtered carcase.
Mycotoxins are an important issue and many pig farms are suffering problems in the herd that emanate from using mycotoxin infected grains and feed ingredients. There is also a lack of awareness in farming communities that mycotoxins are a major cause of productivity decline and sickness in the herd.
While the mycotoxin problem is present on every continent, it is more pronounced in African farms because of the following reasons:
1. the high heat and humidity in Africa provides a perfect environment for fungal growth.
2. Maize and groundnut are a cheaper alternative to soya meal and fishmeal but also provide optimal conditions for fungi.
3. There is also increased use of by-products such as brewery waste, rice and corn and wheat bran as an alternative feed ingredient to reduce feed costs. This factory waste often have a high degree of mycotoxin contamination.
4. Increased mixture of crops grown under different climatic conditions eg, savannah in the north and humid southwest which, when mixed together, can result in a wide spectrum of mycotoxin presence, made more acute in their effects on the pig, poor harvesting method and substandard storage facilities which crack the protective grain pericarp before any drying process takes place and allows surface moulds to gain entry. Poor storage of moist grain (grain with more than 13 percent moisture) – this is common in West Africa, especially where grains are harvested during the rainy season and are not allowed to dry properly and finally, keeping feed that is in a bag on a bare floor or on the wall instead of silo is very common in Africa and this can increase moulding of feed. Such feed should have been stored on the farm on a rack and away from the wall.
Frequency of feeding
For the high-performing exotic pigs to achieve 100kg in 5 months, they need to be fed ad libitum. Ad lib is the feeding management through which pigs are offered as much food as they want. That is, they always have feed in their feeding trough at their disposal 24/7 thus allowing pigs to grow faster as there is less competition for feed.
However, in most African farms, pigs are ration fed with very limited amounts of feed, normally lower than the amount that they can eat (the feed is not available 24 hours a day). While this lowers the cost of food for farmers, it also slows growth rate.

Good evening house.. I'm a newbie in the house though I ve been into fish farming for sometime now. Funny enough I came across this page just last week and as of today, I ve read through ALL the pages. Vast knowledge! kudus guys.

Please I ve some questions.

1. After spawning a female, how long before she can be used again?

2. Are there special tactics to turn a fully grown table size fish to a broodstock or one should just keep feeding till it ages and you notice an orange dot in the eggs?

3. After a successful Hatch, do you need any antibiotics or vitamins for the fries or you just keep feeding them and observing the regular water management?

4. What is the sequence of feed size fries should be feed prior to age/weeks.

5. When is the appropriate time (weeks) to move them outside the hatchery/vat.

Thank you, awaiting your responses.

1.The female can be reused at about 3 months
2.yes ,after they have reached table size u change their diet and nutrition to a more protenous diet
3.it is optional some just feed ,siphon and clean the vat while and sort while others add medication to thier feed to boost their growth and immune
4.you start from 0.2 or 0.3 to 0.5 to 0.8 to 1.5
5.The vat and hatchery doubles as your nursery,you will only need to sort affectively according to sizes because they start canibalizing from 3rd day of hatching kn owing that catfish is highly cannibalistic. you need to go for few practical sessions or just watch the procedure fom start to finish. i have some e-books that i can send to u if u drop ur whatsapp

Sir I intend going into commercial pig farming but I don't have the knowledge at all. What is your advice for me? What do I do first? How can I get the knowledge that I need to raise at least 10 sows for breeding for a start? Can I get them here on nairaland?

you will need to buy and invest in knowledge. if ready contact me

They should stop troubling people, Coronavirus is not for blacks. How many blacks have died from the sickness. Our lack of indepth research dexterity have made up copy what ever black man does whether it suits us or not.

for your information it has killed more blacks proportionally in new york

what is the fate of our single mothers now?the way people are sounding here it is just like they have committed an heinous crime by the mistake.is there no way of dealing with them including their baggage. this is a lesson to our single ladies to avoid premarital sex so that the mistake of baby mama wount come up and men turning them to them to lepers.

This are is also a lesson for us to learn concern concerning our attitude to people that come here to seek for help.if u can help park well and let people who want to help do their thing.don't turn to an antagonistic demon sent from the pit of hell.only raise alarm if u are sure and have concrete evidence to back up your claim that u have tendered.don't let us have innocent blood hanging on our neck without knowing

Vavevivo:
Op thanks for sharing. Your story has given me hope. I contemplated on ending my life today because everything seems to have fallen apart.
My wife will put to birth this month and I have not registered her in any hospital because no money. I sold my laptop two weeks ago just to get us food for the lockdown and my rent will expire on the 17th next month. I’m just hoping for a miracle

don't give up,help is on the way,God the Almighty sorter will sort you.one motivational speaker said killing oneself is like slamming the door on the face of God.u will be aright lass lass

this is the president I voted for and some people claim I wasted my vote.I am still happy with my choice

There are some monikers that are like tom and jerry on nairaland.they don't see eye to eye and here always looking for each others trouble.I will set the ball rolling by naming one which I know.

Practical applications of probiotics in pig production
Increased sows feed consumption, protection against piglet diarrhea, meat quality improvement and many more…
Probiotics are used in all stages of porcine production: sow herd, nursery and growing-finishing pigs. Generally speaking, the use of probiotics aims to establish a healthy gut microbiota, improve health, well-being and productivity of the animals (Cho et al. 2011). However, if we are more specific, the practical application (or result) of using probiotics can be distinct in every context (see table 1). This article briefly describes main applications for which probiotics have been evaluated in different productive stages of swine production.
Table 1. Main applications of probiotics in the swine industry. Adapted from Barba-Vidal et al. Practical aspects of the use of probiotics in pig production: A review. Livestock Science 223 (2019) 84–96.

Sow herd and piglets
Administering probiotic treatments to sows has demonstrated a dual potential, including benefits for themselves and for piglets. Supplementation of sows with probiotics may increase feed consumption during late pregnancy stages or lactation, improving body condition at the end of lactation (Bohmer et al. 2006). This situation is desirable, because it can cause a reduction of the necessity of energy mobilization at lactation. This, in turn, could be the explanation of the reduction in the weaning–estrus interval that has also been reported with probiotics (Hayakawa et al. 2016). Reproductive-performance-related benefits have also been reported with the use of probiotics in sows. For example, an increase in the number of piglets (Apic et al. 2014) or higher piglet growth rates with greater body weight at weaning (Alexopoulos et al. 2004). Furthermore, a reduction of gut pathogens (Kritas et al. 2015), clinical signs of uterus and/or udder disease (Apic et al. 2014), together with fewer clinical signs of diarrhea in piglets (Taras et al. 2006) have also been described. Finally, there is an ongoing scientific interest to assess the capacity of sows to deliver probiotics to piglets in early-life stages (Scharek-Tedin et al. 2015).
Nursery piglets
Up until today, the nursery period is where the use of probiotics is receiving more interest in swine production, with the aim to improve weaning outcome (de Lange et al. 2010). Weanling piglets have low disease resistance, which makes them vulnerable to stress reactions and invasion by pathogenic microorganisms (Konstantinov et al., 2006). This can be a serious problem, as this period is considered critical in terms of productivity, because performance parameters at the first week post-weaning can be correlated to subsequent performance of the pigs up to the market weight (Kats et al., 1992).
Probiotics can potentially act beneficially in these animals in several ways. For instance, it has been reported that supplementing weanlings with probiotics may prevent or improve diarrhea (Bhandari et al. 2008), re-establish microbial balance after a transient drop in favorable bacteria (Krause et al. 2010), protect against pathogenic bacteria (Casey et al. 2007), enhance intestinal barrier function (Guerra-Ordaz et al. 2014) and stimulate immunity (Lessard et al. 2009). As a consequence of one or a combination of the before-mentioned reasons, probiotics have been reported to improve productive parameters of post-weaning piglets in many occasions (Ahmed et al. 2014, Bhandari et al. 2010).
Fattening pigs
The main objective to use probiotics in this phase would be to enhance productivity. Scientific literature published until now would support the idea that although older pigs have more developed immunity, and capacity to resist intestinal disorders, there is still a margin for probiotics to act and potentiate growth; especially in early growing phases or high-density diets (Meng et al. 2010). Improvement of the final meat quality and organoleptic properties could also be another target for probiotics in this phase, as probiotics have been described to affect meat color, marbling and firmness scores (Černauskienė et al., 2011); and reduce potentially zoonotic infections such as Salmonella spp. (Casey et al., 2007). Finally, a weakly explored but interesting potential of probiotics is to reduce environmental pollutants from animal manure. Several probiotics have been reported to be capable of reducing potential pollutants from manure such as fecal noxious gas (H2S) or ammonia (NH3) content, particularly in pigs fed high-nutrient density diets (Yan and Kim, 2013). The direct mechanisms for these effects are still unknown, although indirect mechanisms such as improving feed efficiency, nutrient retention and modulation of gut microbiota are probably involved.

you need the EDI certificate to submit along with your application.

have u done training with an accredited EDI.do that and upload ur certificate. I have doing the training at the moment and I will do my application soonest.

google nirsal microfinance bank.once u attend an accredited EDI training we
with 10k and have a tight business plan.it is own by nipost,CBN and bankers committee.I will send u the process tomorrow. I hope to go into commercial production of pig in ikorodu.so I hope we do business together in the nearest future

why don't u trnitsal micro microfinance bank.that give non collateralized loan at 9% per annum

Ofemmanu1:
30% on 1m.

180% for the 6 months.are u kidding me or u want to kill the business.

PigBarn:
You buy exotic breeds to breed and increase you sow capacity.
Advantages
The farrow large litter of piglets averaging 10-16 piglets
The have less or no fat in there meat
The have high food conversion rate, when feed 2.5 -3kg a day per pig it gains 1kg daily
The have faster growth rate for fattening.

When going for this breeds u don't buy to fatten immediately for profit. You buy to multiple, grow and have enough breeding sows so that each month possible you have 5 sow giving birth to new piglets. This breed enhance better production.

I will advice you go for this breeds if you intend to farm commercially and not backyard farming

great our professor.

PigBarn:
They to can be fatten to slaughter in 6months, weighing 100kg no local breed will give you this.
Modern farming is all about farming right and smart. We plant genetic improved seedlings so do we rear genetic improved animals to maximize profit.

The Nigeria pork industry is so underated , Nigerian still imports pork from South Africa at this time, because most pig farmers lack the proper knowledge of the pork market.
Nigeria is meant to be the highest exporter of pork to the world given the abundance of varieties for protein and carbohydrate for the formulation of pig feeds.
The pork industry is a huge one.

it is not viable in Lagos to buy exotic breed to fatten.in oke-aro,gberigbe and the pig farm where I operate in small scale ,live weight is sold at an average of 460 per kg which means 100kg is 46k ,then how can u fatten profitably when u buy exotic breed weaners or grower for such high price

PigBarn:
Keep the questions coming that's the reason why am here:

Pig farming is not a get rich over night business to be frank with you. If u want to fatten to slaughter I will advice u go for the local breed but if u intend to farm properly in a commercial way you go for the better breeds( landrace and large white) you can start with 10 sows 3 boars and grow fast.

Exotic breeds are been sold per kg, this breeds can weigh up to 350kg, in my location we sell 1000 naira per kg ( live weight) and 1200 per kg for dead weight.

where is your farm where live weight is 1k/kg because I intend to go for commercial pig farming soon. how much is weaners of landrace,large white and duroc

Holycity:
sorry if am asking too many questions

those exotic breed are meant for reproduction or duplication and not fattening to sell.
