Pig is an Omnivorus Domesticated even-toed hoofed mammal. It is variously considered a sub-species of Eurasian boarora distinct species but the American Society of mammal gist consider it the latter (Mammal diversity org). The pigs head plus body length ranges from 0.9 to 1.8 (3 to 6ft) and adult pigs typically weigh between 50 and 350kg (110 and 770lb) with well-fed individual even exceeding this range. But mostly the size and weight of hogs largely depends on their breed compared to other Artiodatyls. A pig head is relatively long and pointed. Most even fed ungulated are herbivores, but pigs are Omnivores like their wild relative Pigs grunt and makes snorting sounds, and a group of pig is called passel or a sounder. Reproduction, female pigs reaches sexual maturity at 3-12 months of Age and come into Estrus every 18-24 days. If they are not successfully bred. The variation in ovulation rate can be attributed to intrinsic factors such as age and genotype as well as Extrinsic factors like Nutrition, Environment and the supplementation of Exogenous Hormones (hughes et al., 1980). Estrus lasts *Corresponding author’s e-mail: abccrcfge28@gmail.com two to three days and the female displayed receptiveness to male is known as “standing heat”. The term “standing heat” is are flexive response that is stimulated when the female is incontact with the saliva of sexually mature Boar (Extension Missouri Edu). The gestation period average 112-120days (Feral Hog Reproductive Biology). Maternal Recognition of pregnancy in pigs occur on day 11 to 12 of pregnancy and is marked by progesterone production from a functioning Corpus Luteum (BazerFuller et al., 2012). Animal Nutrition is important prior to reproduction and during gestation to optimum reproductive performance is achieved. When considered as Livestock, Pig is mostly farmed for its meat known as “PORK”, other food products made from pig include; bacon, Gammon, hamand pork rounds. The head of a pig can be used to make a preserved Jelly called “Head of Cheese” which is sometimes known as Brawn”, liver, Chetterling blood and other offal from pig areal so widely used for food. In some Religions such as Judaism and Islam, pork is a taboo food. Approximately 1.5 billion pigs are slaughtered each year for meat (FAOSTAT.fao.org). The pig milk is not use for human consumption unlike other Animal, the skin is eaten and also used as seat covers, Apparel and other items (Stephanie et al., 2014). The domestic dog (Canis lupus familiaris) when considered a subspecies of the wolf or Canis familiaris
