Body weight and semen production of broiler breeder males as influenced by crude protein levels and feeding regimens during rearing.
An appropriate dietary CP level and feeding regimen during rearing is considered important for controlling BW and improving semen production in broiler breeder males. A total of 640 day-old broiler breeder male chicks of two commercial strains (A and B) received treatments of a factorial arrangement of two CP levels (12 and 16%) of corn-soybean grower diets and two feeding regimens [changing fe...
متن کاملFeeding broiler breeder males. 4. Deficient feed allocation reduces fertility and broiler progeny body weight.
Two experiments were conducted to evaluate the effects of male broiler breeder feed intake on broiler progeny performance. In experiment 1, a low cumulative nutrition program supplied 29,580 kcal of ME and 1,470 g of CP, whereas a high cumulative nutrition program supplied 33,500 kcal of ME and 1,730 g of CP to photostimulation at 21 wk of age. Two diets (HiDiet and LoDiet) were formulated, and...
متن کاملComparative effects of nano-selenium and sodium selenite supplementations on fertility in aged broiler breeder males
It is well documented that aging has negative effects on fertility. With increasing age, the activity of antioxidant enzymes are reduced and because of roosters sperm composition, a high proportion of polyunsaturated fatty acids (PUFAs), the probability of sperm damage increases. The objective of the present study was to compare the effects of nano-selenium and sodium selenite on fertility in a...

were: Choretime, Lubing, Plasson, Val, and Ziggety. Higher average maximum temperatures for the SU (32 C) versus the SP (28 C) trial, made the trials significantly different (SD) and therefore were analyzed separately. While no SD were found in BW (kg) during the SP trial, drinker D significantly reduced 42d BW (2.32) in comparison to the A (2.44), B (2.42), C (2.41), and E (2.44) systems. No S...
متن کاملEffects of growth patterns and dietary crude protein levels during rearing on body composition and performance in broiler breeder females during the rearing and laying period.
The combined effects of growth pattern (GP) and dietary CP level during rearing (2 to 22 wk of age) on body composition and performance were investigated in broiler breeder females from 0 to 40 wk of age. One-day-old pullets (n = 768) were randomly allotted to 48 pens according to 2 growth patterns (standard = SGP and high = HGP) and fed using 1 of 3 dietary CP levels (high = CPh, medium = CPm,...
