What to do if the eggs laid by the laying hens are small?
2021-01-28
In laying hen farms, we sometimes find that some laying hens produce very small eggs, which not only affects production, but also is at a disadvantage when selling, which reduces certain economic benefits. So, what is the reason for the small egg laying? How to solve it? Let's take a look together:
1. Provide a reasonable ratio of energy and protein feed, especially before the start of labor (about 110 days of age), use 10 days to gradually transfer to layer feed. Transition methods are: 110 days old, 2/3 young chicken feed, 1/3 layer feed; 113 days old, 1/2 young chicken feed, 1/2 layer feed; 116 days old, 1/3 young chicken feed , 2/3 layer feed; 120 days old, no matter whether the production starts or not, all feed layers are fed.
2. Strictly follow the feeding standards to provide sufficient feed for the chickens. Generally, young chickens consume about 0.22 kg of feed per day, and the laying hens consume about 0.24 kg of feed per day.
3. Pay attention to the breeding of young chickens to prevent the chicken groups from being too heavy. At the age of 110 days, take samples at any time (take 20 from 1,000) and weigh the weight. The standard weight range is only 80%. If it is less than 80%, you need to increase your weight to prevent laying eggs; if it is higher than 80%, It is necessary to limit the amount of feeding to prevent the chickens from being overweight at the start of production and causing dystocia, and the mortality rate is high.
4. When the chicken starts to lay, the average egg volume should reach 33 grams. If it is less than 33 grams, check the reason. In addition, as the age increases, the egg weight gradually increases. If the increase is slow or does not increase, the reasons should be checked.
