The crude protein content of cotton cake is relatively high, generally 32% to 43%, and the content of methionine is high. The source is wide and the price is low. Using it to replace soybean meal to feed pigs can effectively reduce the cost of feeding. However, cottonseed cake contains gossypol toxin, poor palatability, improper use will cause adverse consequences, for this reason, the following points should be paid attention to when feeding pigs.
It is safe to reduce the free gossypol content to 0.04% or less before feeding. Common detoxification methods: First, detoxification of ferrous sulfate. Soaking the cotton cake with 2% aqueous ferrous sulfate solution can be fed after 24 hours, and can be detoxified by more than 90%. Second, boil and detoxify. Cotton cake crushed, add water, high temperature treatment, heating at 70 °C for 2 hours, 100 °C heating for 1 hour, can make gossypol lose its toxicity, steamed than boiled effect is good, but this method will lose part of the nutrition; Hydrogen sodium detoxification method. Mix 2% sodium bicarbonate solution and cotton cake in a ratio of 1:2. Spread 15-30 cm thick on the concrete floor. Seal it tightly with plastic cloth and place it at room temperature for 24 hours.
Boar bogey feeding cottonseed cake feeding boar cotton cake will prevent sperm development, resulting in thin semen, reduced sperm count, weak vigor and low conception rate.
Cottonseed cake can not be fed to sows. The feeding performance of sows on sows can affect their breeding performance. Even if the detoxification is complete, the amount fed should not exceed 5%.
Feeding of finishing pigs on cottonseed cakes Feeding on finishing pigs with cotton seed cakes works well, but to control the amount of feed, generally do not exceed 10% of the diet, otherwise it will affect its growth.
Supplementation of vitamins and minerals Cotton cakes are poor in palatability, and feeding should be gradual, from little to large, so that pigs gradually adapt. At the same time, it is necessary to supplement sufficient amounts of green fodder (adding multivitamin additives in winter) and compound additives for pigs, which can weaken the toxic effects of gossypol.
Pigmeal cake feeding pigs need to pay attention:
First, must be detoxified before feeding; Second, the boar avoid feeding cotton seed cake; Third, the cotton seed cake can not feed the sow; Fourth, the finishing pigs limit feeding cotton seed cake; Fifth, vitamin and mineral supplements.
