The role of cottonseed meal in feed

Cottonseed meal plays a role in supplementing protein, lysochloric acid, calcium, phosphorus and carotene in feed, and the addition of cottonseed meal in cow feed can also improve the milk fat rate of dairy cows. When adding fat feed materials, we must pay attention to the quality. Do not use moldy or blackened ones.

The amount of cottonseed meal in different livestock and poultry feed:

1. Chicken feed

10% Mel 20% of the diet can be used in broilers, 5% Mel 15% of the diet can be used in laying hens, and the amount of undetoxified meal in the diet shall not exceed 5%.

two。 Pig feed

General suckling pigs, piglets do not use cotton meal, adult pigs can be used in the diet of 10% Mel 20%, sows can be used to 3% Mel 5%.

3. Cattle feed

Cottonseed meal is a constipation feed raw material, which should be used with sesame meal and other soft feed raw materials. Generally, the feed dosage of dairy cows should be 20%, 35% of the concentrate. When feeding fine cattle, it is suitable to be less than 20% of the concentrate, and should be matched with high-quality roughage with high carotene content. Beef cattle generally account for 30%, 40% of the concentrate.

4. Sheep feed

The use of cottonseed meal in sheep feed should be combined with high-quality concentrate, and the expected dosage should not exceed 50% of the concentrate.

When buying cottonseed meal, you should observe its color, shape and so on. The sensory characters are flake or cake shape, fresh and consistent yellowish brown color, less black fragmented cottonseed shell, less cotton wool, no mildew and caking phenomenon. Grab a handful of cottonseed meal in hand, carefully observe whether there is adulteration or not, and estimate the proportion of cottonseed hull and the content of cotton wool. If the content of cottonseed hull and cotton wool is higher, the quality of cottonseed meal is poor. The crude protein is lower and the crude fiber is higher.

The moisture content shall not exceed 12%. Grasp a handful of cottonseed meal, and then loosen it. If the cottonseed meal is held into a lump, the moisture content is higher, and if it is loose, the moisture content is lower. The cottonseed meal is dumped and the hand residue is observed. if there is more residue, the moisture is higher, and vice versa. Touch the cottonseed meal by hand to feel its humidity. In general, the temperature is higher and the moisture is higher. If you feel hot, a large number of stacks are likely to ignite spontaneously.

Because the possibility of aflatoxin infection of cotton meal is relatively high, being eaten by livestock and poultry will cause slow growth and other conditions, eating can be tested for aflatoxin when necessary.
