Amino acid requirements of broiler breeders at peak production for egg mass, body weight, and fertility.
Two trials were conducted to determine the amino acid and protein requirements of broiler breeders at peak production. In trial 1, 32-wk-old Cobb 500 broiler breeders with similar BW were selected to determine the digestible amino acid requirement for daily product output (g of egg mass + g of BW gain/b/d) and feed conversion (g of feed/g of product) for Met, Phe, Arg, Ile, Lys, and CP in a 42-...
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...

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...

The objective of this cooperative research project is to quantify Listeria monocytogenes in ready-to-eat (RTE) uncured and cured poultry, pork and beef products that have been pre-sliced by the manufacturer or sliced upon demand in supermarket delis. This data will expand on a previous study sponsored by the Food Products Association (formerly National Food Processors Association; Gombas et al....
متن کاملThe effects of oviposition time on egg weight loss during storage and incubation, fertility, and hatchability of broiler hatching eggs.
An experiment was conducted to determine the effect of time of oviposition, generally representing different positions in the normal egg laying sequence, on egg weight loss during storage and incubation, and on fertility and fertile hatchability of eggs from mid-lay (42 wk) and old (67 wk) broiler breeders. A total of 1,800 eggs (900 eggs per flock age) were collected during 10 consecutive days...
