EFFECT OF DIETARY SUPPLEMENTATION OF ORGANIC SELENIUM AT DIFFERENT LEVELS ON REPRODUCTIVE PERFORMANCE OF

CHAPTER ONE

 1.0 INTRODUCTION
 1.1 Background of the Study
 It has been discovered that inadequate supply of animal protein from traditional livestock: cattle, sheep, goats, pigs and chicken is responsible for the decline in animal protein consumption in many developing countries of the world. According to FAO (2006), about 854 million people representing 12.6% of the world population are severely malnourished. To correct this, Biobaku and Ekpeyong (1991) indicated that non-traditional meat sources suitable for small scale farmer need to be explored. Iheukwumere and Okoli (2002) defined a rabbit as a mini-livestock with high reproductive potentials. It has a unique ability which serves as a flexible financial reserve. It has short gestation length, exhibits early maturity, has high prolificacy and also has the ability to re-breed shortly after parturition. These attributes lead to short generation interval (Lebas et al., 1997; Effiong and Wogar, 2007). Today, rabbit as a micro-livestock production is part of value chain development in the present agricultural transformation agenda (ATA). This is because of the huge potentials of rabbit production in supplying the much needed animal protein intake. Other such potentials include low capital outlay, good converter of feed (Biobaku et al., 2002). Furthermore, the characteristic small body, size, rapid growth and ability to live on forage has made rabbit production lucrative, especially where production is a very big business in some parts of Nigeria where the meat is receiving an encouraging patronage. It is an alternative livestock where trypanosomiasis has posed a threat to cattle and other livestock production. Rabbit is a monogastric and its meat differs from other animals in protein content, (Aduku and Olukosi, 1990). The meat also contains low cholesterol, fewer calories and a low percentage of fats compared to beef, pork, chicken or lambs, (Aduku and Olukosi, 1990). Janieri (1987) reported that this attributes of low cholesterol value makes it a life saving animal protein source for people with high blood pressure. The meat is also tender and juicy, an attribute that makes it suitable for all categories of ages both young and old. Apart from being a good source of white meat which is “pearly white”, rabbit can be used for heart patients, provides wool (fur), skins, manure and toys. It is the only farm animal which produces meat at 10 to 15 times or more of its weights in a year through progenies. Being such multiplier, it is expected to ease the demand of pressure in chicken and mutton (Banergee, 1998). Rabbit has been observed to excel other livestock: cattle, sheep and goats, but ranks close to chicken in respect of growth rate, feed conversion efficiency (FCE) and meat quality. Of all the livestock species, rabbit is most efficient converter of feed to flesh (Agunbiade et al., 2001). One kilogram of rabbit meat only requires one quarter of the fed energy required to produce an equivalent quantity of lamb or beef and only 70 percent of the feed to produce the same amount of pork (Lebas and Matheron, 1982). Rabbit production is an ideal enterprise for young people because it requires limited capital investment for housing and equipment. A breeder with a pair of rabbit can produce 60 – 80 rabbits each year to sell or eat (Elmer, 1990). The optimum exploitation of rabbit prolificacy and performance can be achieved through proper feeding (Iheukwumere et al., 2005), while poor nutrition will delay sexual maturity in rabbits, resulting in low financial return to the farmer (Asuquo, 1993). This suggests that increased feed and nutrient level be given to breeding rabbits as a means of increasing litter size, adequate maintenance of pregnancy and subsequent milk let down by the doe (Lebas, 1983; Effiong and Wogar, 2007). Also, dietary supplements such as selenium with intent to maintain healthy systems and support recovery and healing are necessary for better performance of the rabbit. Selenium, essential trace mineral is necessary to maintain good health of animals but is required only in small amounts. Selenium (Se) has good properties in improving fertility parameters especially in females. They are antioxidants and have protective and preservative characteristics (Orffa, 2010). Hence, this serves as dietary supplements of breeding does for higher productive performance.
