Thesis Abstract

<p> Four West African Dwarf sheep<br>were used to investigate the effect of brewers’ spent grains supplementation on<br>the utilization of mixed forage diets. The sheep were randomly assigned three<br>dietary treatments treatment 1- <i>Gliricidia<br>sepium (G. sepium</i>) + 200 g brewers’ spent grain (BSG), treatment 2- <i>Panicum maximum </i>(<i>P. maximum</i>) grass + 200 g BSG, and treatment 3- <i>G. sepium</i>&nbsp;(50%) + <i>P. maximum</i>&nbsp;(50%) + 200 g BSG, with four rams per treatment diet for<br>42 days. Data were collected on<br>feed intake and faeces voided during a digestibility trial. The results<br>revealed that animals fed on Treatment1 recorded the highest (p&lt;0.05) total<br>dry matter intake (1626.83 g), total crude fibre intake (464.56 g), total<br>nitrogen free extract (846.35 g) and total organic matter intake (1563.69 g).<br>Animals on treatment 2 recorded the highest (p&lt;0.05) total crude protein<br>intake (274.06 g) and total ether extract intake (73.19 g). Highest ash intake<br>was recorded in treatment 3 (76.65 g). Animals fed treatment 2 recorded the<br>highest digestibility % (P&lt;0.05) in all nutrient parameters, while the least<br>was observed for those fed diet treatment 3. Animals fed treatment 2 utilized their diet efficiently<br>and which resulted in best digestibility while the least efficiency of<br>utilization was observed in animals on diet treatment 3. Results from this<br>study revealed that supplementation of forages with agro-industrial by-products<br>such as BSG enhances utilization of forages. <br></p>

Thesis Overview

<p> </p><p>Inadequate feeding is a major limiting factor to small<br>ruminant production in tropical Africa (Ademosun, 2010). Fodder is of poor<br>nutritional value for most of the year due to the rainfall pattern. In the arid<br>and semi-arid zones, rainfall is less than 600 mm and between 600-1000 mm per<br>year, respectively. Many conventional diets for ruminants in the tropics are<br>poor quality roughages typified by high Neutral Detergent Fibre (NDF), low<br>nitrogen contents and slow fermentation rates. This poor dietary combination<br>leads to decreased intake, weight loss, increased susceptibility to health<br>risks and reduced reproductive performance. Including herbaceous legumes in<br>these feeding regimes helps to rectify some of the problems associated with low<br>protein and high fibre diets. Poppi and Mclennan, (1995) suggested that to<br>optimise the benefits of lablab as a feed source, it should be grazed in<br>conjunction with poor quality feedstuffs.</p><p>The quality of available forage is low and browse species<br>which can provide higher levels of proteins and carbohydrates are sparsely<br>dispersed. In the humid and sub-humid zones, up to six months of the year can<br>be rainless, resulting in poor quality forages. The rapid buildup of cell-wall<br>materials and decline in crude protein (CP) content with maturity reduces the<br>nutritional value of the forages. Little is known about the nutritional value,<br>distribution, palatability, seedling vigour and seasonal production of the<br>forage species that characterise the natural grassland. This is particularly<br>true of the arid, semi-arid and sub-humid areas which contain 75% of the sheep<br>and 80% of the goats of tropical Africa and where the rangeland is the most<br>important source of food (FAOSTAT, 2013). Besides the use of browse, other<br>strategies can be employed to improve the feeding of animals. During the dry<br>season, the quality of available herbage is so low that, unless the animals<br>have access to supplementary feeds, they lose weight. These supplementary feeds<br>can be obtained from agro-industrial by-products such as residues of oil<br>extracted from oil bearing seeds (groundnuts, coconut, palm kernels, cotton<br>seed, soyabean etc), by-products of grain processing (maize, rice, wheat,<br>sorghum, millet etc), peelings of crops (yams, cassava, potatoes, plantains</p> <br><p></p>
