The proximate chemical composition, mineral, fatty acid, and amino acid profiles of Nigella seed meal (NSM) was determined. In addition, apparent (AAAU) and true (TAAU) amino acid utilization, and apparent (AMET) and true (TMET) metabolisability were determined using a force-feeding…
This study was conducted to assess the effect of nettle supplementation on heat-stressed broiler performance and physiology. A total of 540 Ross-308 broiler chicks were randomly assigned to nine treatments each with six replications of 10 birds. Three contents of…
This study evaluated the effect of zinc oxide (ZnO) on growth performance, serum biochemistry, and gut microbial counts of broiler chickens reared in a tropical environment. A total of 120 one-day-old broiler chicks were assigned using a completely randomized design…
The effects of replacing soybean meal (SBM) with graded levels of morula kernel cake (MKC) on growth performance and haemo-biochemical parameters in broiler chickens were studied. Four iso-nitrogenous and iso-caloric diets were formulated by replacing the SBM component at 0,…
Shrimp waste meal (SWM) is a by-product from the processing of shrimp for human consumption. The value of SMW in feeding poultry is not well documented. The objective of this study was to determine the energy value and optimal inclusion…
This experiment was conducted to determine the interaction effects that resulted from supplementation of low-protein diets with leucine (Leu), valine (Val), and glycine-glutamic acid (Gly-Glu) on growing broiler chicks from 11 to 24 days old. Two levels of digestible Leu…
The aim of this study was to determine the effect of peppermint and thyme essential oil mist on performance, blood parameters and lymphoid organ indices in broiler chickens. The experiment was conducted on 360 broilers raised until 42 days of…
This experiment was designed to assess the hypothesis that feeding broilers with peanut pod as an insoluble fibre source will result in improved gut digestive capacity growth performance. The experimental diets consisted of a control diet and three diets containing…
Spirulina platensis is a good candidate as an in-feed antibiotics substitute for broilers. However, its use seems impractical owing to its high price, especially when being administered throughout the whole rearing period. This study aimed to investigate the effects of…
This trial was conducted to investigate the effects of supplementing saturated and unsaturated fat sources on serum metabolites and meat physiochemical parameters in the diets of broiler chickens. A total of 360 day-old male broiler chicks (Ross 308) were used…
Cassava pulp is an energy-rich by-product of the tapioca industry, and is known as a good media for growing filamentous fungi. It may therefore be not only an alternative to maize in poultry diets, but also a carrier for beneficial…
A 3 × 3 factorial experiment (4 pens/treatment, 10 birds/pen) was conducted with 3 levels of supplemental taurine (Tau) (0.0, 0.25 and 0.50%) and 3 levels of dissected bile acid (DBA): 0.0, 0.25 and 0.50% of the diet were arranged…
Four commercial organic acids and a reference antibiotic, Neoxyval, were administered to commercial broilers to evaluate the efficacy of these products during pre- and post-challenge with Salmonella enterica subsp. enterica Typhimurium (S. Typhimurium) on selected indicators of their antioxidant status…
This study was conducted to evaluate the effects of replacing soybean oil (SBO), typical in broiler diets, with a less expensive commercial fat blend, Kofat (KOF). A 2 x 2 x 2 factorial experimental design was used to study the…
This study was conducted to compare the withdrawal or reduction of the vitamin premix (VP) from broiler diets at between days 29 and 42 of age on the characteristics of leg bones of the broilers in a battery cage (Trial…
There are a number of laboratory methods that could be used to estimate the adequacy of full-fat soybean (FFSB) heat treatment. The protein despersibility index (PDI) has been claimed to have the most constant response to the heating of FFSBs…
A 2 by 4 factorial experiment was performed to investigate the influence of ascorbic acid and various dietary energy concentrations on bone development. Two groups of 12 broiler chickens were allocated to one of each of the following dietary treatments:…
In this article progress attributable to genetic selection in the poultry industry is discussed in three sections: genetic progress in broilers and broiler breeders, in laying hens, and in disease resistance. Selection methods are evaluated and future objectives are suggested…
An experiment was conducted to determine the feeding value of sweet white lupins (Lupinus albus variety Buttercup) for broilers up to 8 weeks of age. Two isocaloric and isonitrogenous starter (0 - 4 weeks) and finisher (4 - 8 weeks)…
Five experiments were conducted to devise a feeding strategy to reduce fat deposition in broiler chickens. From these experiments it was determined that early feed restrictions, beginning at 7 days of age, decreased body fat, improved FCE, and had little…
