If only a few fetuses die, abortion rarely occurs; instead, mummies are delivered at term, along with live piglets or stillbirths. 1. Non-infectious Causes High ambient temperature (>32°C [>89.6°F]) is associated with increased returns to estrus, increased embryonic mortality, decreased farrowing rates, and small…

Artificial insemination and Heat Detection in Pigs

Artificial insemination and Heat Detection in Pigs

Artificial insemination refers to the introduction of either frozen or fresh semen into the female reproductive tract of an estrus pig using a catheter to achieve conception. Its very unfortunately that sometimes non estrus pigs are inseminated due to inadequacy in knowledge on heat detection/ heat signs by both farmers and technicians. The semen must be got from a proven sire that is free from diseases and other detects especially the congenital defects. AI requires a higher level of management than natural mating.

The Recommended Protein Source ingredients for Pigs

The Recommended Protein Source ingredients for Pigs

The following are recommended levels and maximum inclusion rates of protein source ingredients in the rations for pigs. Soy Beans and By-Products: Soy protein has a very high lysine content, which make this protein source very valuable. It also contains an Anti-Trypsin Factor (ATF), a growth stunting component that disturbs the protein digestion. It can be eliminated by toasting the soybean.  It’s crude protein content ranges from 36%- 43 % depending on the varieties and other environmental factors. Sow can take up to 15%, Fatteners not more than 10%, to…

List of Animal Feed Raw-Materials and their Uses

List of Animal Feed Raw-Materials and their Uses

Maize bran: this is an energy feed source. It is low in protein but high in crude fiber and thus can be fed up to 15%, fatteners up to 30% and sows up to 30%. The high-level crude fiber in feed has negative effect on digestion. Wheat bran: this also provides energy to pigs. It has level of protein, lysine and methionine but very high in crude fiber and the Maximum amount of it allowed in sow feeds is 25%; Fatteners feed should not contain more than 15% because of…
