Feed Restriction in Broiler Chickens Production
The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
متن کاملEffect of environmental temperature on muscle protein turnover and heat production in tube-fed broiler chickens.
The present experiments were undertaken to investigate the effects of environmental temperatures on growth, abdominal fat content, rate of muscle protein turnover, and heat production in tube-fed intact male broiler chickens. Plasma concentrations of thyroxine (T4), triiodothyronine (T3), and corticosterone (CTC) were also examined. Chicks (15 d old) were kept at different environmental tempera...
متن کاملStruggling behavior in shackled male and female broiler chickens.
Anecdotal evidence suggests that the struggling behavior of shackled broiler chickens may be positively related to compression of the shank and the probable associated discomfort: birds with large shanks tend to struggle more violently than do those with smaller shanks. Males are generally heavier and have thicker shanks than females. Therefore, we tested the hypothesis that, because the leg ga...
متن کاملDietary Selection of Fat by Heat-stressed Broiler Chickens
A total of 160 d-old male broiler chicks (Cobb) were brooded for three weeks and then maintained at 24±1°C. Commencing from d 21, chicks were assigned to one of four feeding regimens: (1) diet with 8% palm oil (PO), (2) diet with 8% soybean oil (SO), (3) diet without added fat (control), (4) a choice of PO, SO and control (CH). The diets were formulated to maintain a constant ratio of energy an...
متن کاملOchratoxicosis in Broiler Chickens:
This experiment was conducted to evaluate the effects of ochratoxin A (OTA) on the function and histology of the liver, kidney and bursa of broiler chickens fed OTA contaminated rations. Two hundred forty one-day-old male Ross broiler chicks were used, they were randomly divided into 3 dietary experimental groups of 80 birds and given rations containing 0 (control), 400 or 800 μg OTA/Kg feed. T...
