Environment and Management : Broiler Breeders
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 کاملEffects of environmental temperature and dietary energy on energy partitioning coefficients of female broiler breeders.
With increasing disparity between broiler breeder target weights and broiler growth potential, maintenance energy requirements have become a larger proportion of total broiler breeder energy intake. Because energy is partitioned to growth and egg production at a lower priority than maintenance, accurate prediction of maintenance energy requirements is important for practical broiler breeder fee...
متن کاملOptimizing Reproductive Output From Female Broiler Breeders
taken were body weight gain (BWG), gain to feed ratio (GF) and percent of foot ash (FA) at 4, 8, and 15 d of age. A significant linear response (P<0.05) was observed in growth performance and FA in birds receiving graded levels of PP at all ages, confirming the sensitivity of the procedure. No significant differences were found in FA percent between groups receiving TP or DP at all ages (13.5 v...
متن کاملStochastic model of egg production in broiler breeders.
A stochastic model was developed to simulate the egg production of broiler breeders in response to changes in BW. The first step involved the construction of a diagram incorporating dependent and independent variables and their relationships to ovulation rate and egg production from 8 equations based on experimental results. The model was based on existing experimental data, and stochastic proc...
متن کاملAbrupt or gradual increases in photoperiod for broiler breeders
Cobb 500 broiler breeder females (n = 832), which had been raised to achieve a typical 20-week body weight of 2.1 kg, were subjected to an abrupt or gradual increase in photoperiod to determine the effects on reproductive performance. One group (n = 416) was reared on 8-h photoperiods till 19 weeks and abruptly transferred to 16-h photoperiods. Another group (n = 416) was reared on 8-h photoper...
