Weighing broiler breeders accurately

摘要

Most people will agree that the single most important piece of information about a breeder flock is the average body weight or the flock's reaction to feeding levels. If body weight is the most important piece of information, it is good to know howwe should weigh breeder chickens." Dr Jeanna L Wilson, Extension Poultry Scientist, at the University of Georgia, USA, says in a newsletter of the Cooperative Extension Service. "Weigh birds individually from as early as possible, preferably from 2 weeksof age. For some scales, the birds must weigh on - half to three-quarters of a pound (220-300 g) before the weight will register. Weigh early to determine what type of flock you have. Chicks from a young breeder flock will be smaller than those from a mid-lay or old flock. If the flock is behind in body weight at 2 weeks a few more days of starter diet or an hour or two more light for a few days may correct this problem early and avoid being behind all during rearing. Flock uniformity problems can be noted early as well."
