High-yield layer chicken discriminating method
Currently, the industry of laying hens has developed rapidly, and some large-scale farms have emerged one after another. How to discriminate whether or not hens have high yields and to eliminate them as early as possible in broiler breeders plays a key role in improving breeding efficiency. According to a farmer engaged in laying hens for more than 10 years, if the laying hens are not producing eggs until the 180th day, they will have to judge laying hens as early as possible. There are four ways to judge: 1. Look at the anus, if the egg The chicken's anal ruddy and shiny, then this kind of laying hens should be preserved, on the contrary if the laying hen's anus is pale and dull, the hens should be eliminated in time; the second is to check the pubic bone spacing, if the pubic bone spacing is not three fingers wide, this The egg hens must be eliminated in time; the third is to look at the hen's hen's crown. If the hens are pale and colorless, the surface is like a layer of film, this kind of chicken must be eliminated in time; the fourth is to look at the chicken feet and the length of the chicken feet to the knees is not enough. The chicken that feels shorter should also be eliminated. Pumpkin Seeds,Roasted Pumpkin,Raw Pumpkin Seeds,Salted Pumpkin Seeds Wuyuan county dafeng oil food co.,ltd , https://www.dafengfood.com.cn
