THE INFLUENCE of PROTEIC FEED TYPE on GROWTH PERFORMANCE of BROILERS
Abstract
An experiment was conducted in order to assess the effects of supplementation traditional recipes with different forage meals from oil processing industry, in particular biofuels. Experiments were conducted on broilers, divided into four groups: a control group (fed with commercial feed), group 2 (fed with supplement of soybean meal), group 3 (fed with rapeseed meal supplement), and group 4 (fed with sunflower meal supplement). Ratios were then balanced regarding energy-protein by adding oil. Food supplementation has favorable effects on productive performance of broilers. Lots 2, 3 and 4 recorded higher average body weight up to 5.57% compared to the control group. Rapeseed meal in the first 4 weeks of life, determined similar average body weight evolution as soybean meal, demonstrating the possibility of substitution. In the first two weeks of life sunflower meal determines backlogs of growth, but during the finishing period, its effects are closely after those of soybean meal. The most irregular lot is that fed with sunflower supplement effect observed from the first period of growth, possibly due to the influence of ration higher cellulosic level. The aim of the study was to assess the effects it has on broilers, supplementation of traditional recipes with different meals from the oil processing industry. These meals are produced in increasing amounts with the development of biofuels industry.
