1. The crude protein content of broiler (9-20 weeks old) should not exceed 14.5%. The lower feed crude protein content at this stage is conducive to a longer egg-laying rate in laying hens.
2. The content of crude protein in the feed at the beginning of production (around 21 weeks of age) must be determined by the feed intake of the layer at that time. At this stage, each layer must be guaranteed to consume 19.6 grams of crude protein per day. Therefore, when each layer of chickens feeds 100 grams a day, the crude protein content of feed should reach 19.6%; when the intake increases to 120 grams, the crude protein content of feed should be reduced to 16.5%. The egg production rate of first-laying hens was quickly pushed to the peak.
The daily requirement for crude protein in layers after 3 and 42 weeks of age will drop to 17.8 grams. With the increase of egg production rate under the natural and daily intake, the crude protein content of commercial layer chicken feed will drop to about 15%. Some breeders mistakenly believe that the drop in egg production rate is due to insufficient crude protein content in the feed to increase the crude protein content of the feed. The results not only affect the health of the chicken population, but also increase the cost of raising chickens.
The difference between the taste of purple Onion and yellow onion
Purple onions and yellow onions also have a big difference in taste. Purple onions have a lighter spicy taste and a slightly sweet taste. They can be eaten raw, but the yellow onions are particularly spicy. They cannot be eaten raw and are suitable for frying. Eat after making or making soup. In addition, the purple onion has relatively thick flesh and high juice content, while the yellow onion has very thin flesh quality and low juice content.
