This study was conducted to assess the effects of phase feeding on growth performance of broiler chicks. The experimental work consisted of a 7-week trial feeding, in which three different feeding programme. Three experimental diets formulated to contain different levels of metabolizable energy (ME) and crude protein (CP); namely a broiler starter diet containing approximately 3072 Kcal ME/kg and 23.9% crude protein, a grower diet containing 3118 Kcal ME/Kg and 21.8% crude protein, and a finisher diet containing 3200 Kcal ME/kg and 18% crude protein. The results diets not reveal any significant differences in productive parameters, but indicated marked trends in differences among the experimental treatment. These differences showed that the highest feed consumption and live weight gain were attained by the group of birds fed the starter diet throughout the experimental period. The starter diet followed by the finisher diet for four weeks resulted in the lowest total feed consumption, reasonably high body weight gain, lowest feed conversion ratio and highest dressing percentage. It can, however, be considered under the conditions of the present experiment that the three experimental feeding programmes supported similar productive performance of broiler, indicating a slight economic advantage of feeding the starter diet followed by the finisher diet.
This experiment was designed to evaluate different levels of Leucaena leucocephala leaves (LLL) which is treated by sun drying or soaked on small ruminant's performance. Leucaena leucocephala leaves were included in small ruminant diets at four levels; 8%, 16%, 24% and 32% respectively. Results revealed that the overall feed intake, body weight gain and feed conversion ratio were significantly (P < 0.05) affected by the dietary treatments. Concerning hematological parameters ESR, Hb and PCV% were within levels between species and condition was not significantly (P > 0.05) different as affected by levels of leaves inclusion. Plasma GOT, ALP and total protein were within levels of inclusion and condition of leaves in the two animal species were highly significantly (P < 0.05) different. Plasma albumin, globulin, Ca, Na and P as affected by condition, levels and species were not significantly (P > 0.05) different.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
