Response of broiler birds to diets containing graded levels of rice milling waste and supplementary yeast

Project Abstract

<p> </p><p>Eighty day-old broiler chicks were used for feeding trial carried out to determine<br>the effect of graded levels of Rice Milling Waste (RMW) and Bioactive Yeast<br>(Saccharomyces cerevisae) which has been shown to secrete enzymes that help to<br>digest crude fiber and organic matter.importance of forest to people in the study area. The linear regression analysis with<br>an R2 of 0.702 showed that about 70% of the total variations in the income from fuel<br>wood were caused by the specified independent variables in the model. On ruralurban<br>interdependence on forest, (79%) of money and income related benefits flow<br>from urban to rural areas; (88%) of benefits relating to innovative ideas on forestry<br>management and conservation flow from urban to rural areas, about (68%) of forest<br>related market information spread from urban areas to the people in rural areas while<br>about (55%) of awareness of the importance of forest and its related products flow<br>from the urban to rural This suggest that supplementing broiler<br>ration with bioactive yeast may improve the digestibility and efficiency of<br>utilization of RMW. The 80 broiler chicks used in this study were randomly<br>distributed in five groups of sixteen birds each. Each group was subdivided into<br>four replicates of 8 birds each. Group 1 was placed on experimental diet made of<br>1.5 g/kg yeast basal feed and no RMW, Group 2 was fed on a diet of 1.5 g/kg<br>bioactive yeast, basal feed and 10% RMW, Group 3 and 4 were fed feed containing<br>1.5 g/kg bioactive yeast, 15 and 20 % RMW respectively while group 5, the control<br>had no RMW and bioactive yeast. Feed and water were given to the birds ad<br>libitum.<br>Daily feed intake and weekly weight gain were determined. Data were<br>collected on nutrient intake, growth performance, feed intake, growth rate, weight<br>gain, feed conversion ratio, apparent nutrient retention, cost benefit analysis and<br>carcass weight. Bioactive yeast supplementation resulted in a significant (P&lt;0.05)<br>reduction in feed intake and cost. The results showed that up to 20% RMW with<br>bioactive yeast (Saccharomyces cerevisae) supplementation are adequate for<br>oprimum growth of broiler birds. However, more research work should be done to<br>determine the usage of bioactive yeast in commercial broiler feed production.</p><p><br></p> <br><p></p>
