From the beginning of egg production to the peak production season of laying hens, during the cultivation process, farmers will add some sand to the feed of the layers. However, they do not know much about the specific effects of the sand, but only think that the sand is beneficial to digestion. Increased digestion and absorption, most farmers do not have strict requirements when using this point of view is not correct, the amount of sand in the feed is strictly required, the following specific talk about the amount of sand in the feed.
The chicken is very sensitive to the amount of sand, directly affecting the chicken's egg production and health.
On the basis of ensuring other nutrients, adding 8% of sand to the compound feed was the best. The chicken had the most appetite, the best mental and physical condition, and the highest egg production rate.
When the sand is below 8%, the chicken's egg production rate is not significantly increased.
When the sand is more than 8%, the chicken's egg production rate will decrease.
The higher the proportion of sand, the lower the egg production and the mental state.
In summary, the sand occupies a certain value in the feed, so farmers need to add sand in an amount of 8%, not too much or not to add, otherwise it is not conducive to the chicken's egg production, and is detrimental to the health of the chicken development.
