Productive performance and histological features of intestinal mucosa of broiler chickens fed different dietary protein levels.
To evaluate the effect of decreasing dietary protein on growth performance, carcass traits, and intestinal mucosal morphometry, 180 female Hubbard strain broiler chickens were divided into 3 groups and fed 3 isoenergetic diets ad libitum from 14 d of age until slaughter age (49 d). The treatments varied according to 3 protein levels: high-protein diet (HiP, 22.5% CP, DM basis), medium-protein d...
متن کاملEffects of Different Oils on Productive Performance of Broiler
Six hundred day old unsexed broiler chicks were used in a 42-d trial at Chittagong Veterinary and Animal Sciences University Poultry Farm to find out the effects of different oils on productive performance of broilers. The chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. Each treatment had 150 birds, with...
متن کاملEffects of Lipotropic Products on Productive Performance, Liver Lipid and Enzymes Activity in Broiler Chickens
In a 42-d experiment, 576 one-day-old Vencobb 308 broiler chicks were used to investigate the effects of lecithin extract (0.5 g/kg), choline chloride 60% (1 g/kg) and Bio choline (1 g/kg) in diets of moderate and high energy in a 4 × 2 factorial arrangement on performance and certain physiological traits in broiler chickens. The inclusion of Bio choline and lecithin extract in the diet signifi...
متن کاملPerformance Characteristics and Nutritional Comparison of Broiler Chickens Fed with Barley and Triticale Based Diets
This study was performed with growing chicken (14 to 56 d of age) to evaluate the effects of feeding them a barley or triticale-based diet. The treatments were corn diet (1) as a control, hulless barley diet with (5) or without (2) enzyme, triticale diet with (6) or without (3) enzyme and hulled barley diet with (7) or without (4) a commercial β-glucanase enzyme. In a digestibility trial, 21 ma...
متن کاملPerformance and physiological parameters of broiler chickens subjected to fasting on the neonatal period.
Broiler chicks aged 12 h after hatching were allotted according to a block design in a 7 x 2 factorial schedule of 14 treatments and four replications of 50 chicks each one. The main experimental factors were fasting for 0, 6, 12, 18, 24, 30, and 36 h after chick placement and sex. Independent of sex, fasting had a negative linear effect on weight and productivity of broilers at market age (42 ...
