Two experiments were conducted to evaluate the performance of weaner rabbits fed maize husk based diets with or without enzyme supplementation. In the first experiment, thirty six weaner rabbits were used for the study. Maize husk replaced rice offal at 0, 4, 8, 12, 16 and 20% inclusion levels for treatments one to six respectively. Each treatment consisted of six rabbits and each rabbit served as a replicate in a completely randomized design. In the second experiment, each treatment consisted of six rabbits and each rabbit served as a replicate in a completely randomized design. The experimental diets consisted of 20% maize husk supplemented with enzyme at 0.00, 0.02, 0.03 and 0.04% for treatments one to four respectively. Maize husk had significant (P<0 .05="" affected="" and="" average="" b="" body="" cell="" conversion="" cost="" daily="" effect="" feed="" final="" gain.="" gain="" haemoglobin="" kg="" level="" not="" on="" packed="" per="" ratio="" significantly="" volume="" weight="" were="">0.05) by dietary maize husk.

CHAPTER ONE
1.0INTRODUCTION
Inadequate animal protein in the diets of people in developing countries has called for the integration of some micro livestock in the farming system as sources of animal protein. Productivity of these livestock will depend to a large extent on their ability to utilize feeds that have no value in human diets. Increased rabbit production is one way of meeting the animal protein requirements of the Nigerian populace (Iyeghe-Erakpotobor et al., 2002). Increased production of breeders can be ensured through proper nutrition and feeding of weaner rabbits. Supply of meat always remains a major constraint in animal production due to the ever increasing cost of conventional feedstuffs occasioned by the competition between man and livestock (Amaefule et al., 2004). The key to abundant animal production is the availability of cheap and balanced feed. Feed dictates how many animals you can grow and how fast they can mature for the market (Aduku, 1992).
Weaner rabbits require 2400-2600 kcal ME/kg of feed 15% crude protein and 9-17% crude fibre (Aduku, 2005). The fibre requirement is higher than that of monogastric animals, because rabbits have a large caecum with microbial organisms which aid in the breakdown of the high fibre. Rabbits possess various attributes that are advantageous in comparism to other livestock, Taylor et al., (1989) noted that rabbit meat is of excellent protein quality, low in total as well as saturated fat, cholesterol and sodium. Therefore, rabbit production is considered a good source of meat in the developing countries where there is an abundance of agro-industrial by-product feedstuffs.
PERFORMANCE OF WEANER RABBITS FED MAIZE HUSK BASED DIETS WITH AND WITHOUT ENZYME SUPPLEMENTATION
This study was conducted to evaluate the growth response and haematological indices of broiler chickens fed corn-soya based diets supplemented with or without protease enzyme. Two hundred and forty (240) one-day old Arbo-acre broiler chickens were assigned to six dietary treatments. Each dietary group had 40 birds with 4 replicates of 10 birds... Continue Reading
ABSTRACT The evaluation of Kolanut pod husk (KPHM) as substitute for maize in the diet of African catfish (Clarias gariepinus) was investigated for period of eight (8) weeks. KPHM was substituted for maize at 0% (control (Tl)), 2S% (T2), SO%(T3), 7S% (T4) and I00% (TS) in the five different diets .C. gariepinus fingerlings (average Weight 3.02g to... Continue Reading
ABSTRACT A study was conducted to evaluate the effect of 20% inclusion replacement of maize with peeled cassava root meal and unpeeled cassava root meal with and without enzyme inclusion. A total of 90, 42 weeks old black Harco layers were divided into 6 groups with 3 replicate for each group. Each replicate had 5 birds. The 6 diets comprise of... Continue Reading

Silicon dioxide , also known as silica (from the latin silex), is an oxide of silicon with the chemical formula SiO2, most commonly found in nature as quartz and invarious living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials existing as a... Continue Reading
ABSTRACT The study involved 16 yreaner crossbred (New Zealand White and Chinchila) rabbits of about eight weeks of a.fetz with initial average weight of 0.69 kg. The animals were offered a measured amount of their respective diets. The level of replacement of groundnut cake with Gliricidia leaf meal (GLM) were 0, 25 50 and 75%, to give four diets...

ABSTRACT There has been a gradual increase of the price of feed resources from conventional protein leading to the inadequate supply of animal protein. Leucaena leucocephala (lam) is a leguminous browse plants that can be used in diets to replace or used in combination with protein source conventional feed ingredients. It's use has been...

ABSTRACT In a study at KNUST weather station, the crop co-efficient values at initial, development, mid-season, and late season stages of ABONTEM MAIZE (hybrid variety) were determined as 0.42, 0.98, 1.05, and 0.32, respectively. These locally determined values of ABONTEM hybrid maize compared favourably with those recommended by FAO. The... Continue Reading
