Nutritional value of palm meal to beef cattle

Palm meal is a by-product of palm kernel hulling and oil pressing. Its shape and color are similar to those of rapeseed meal, and its smell is slightly chocolate. The quality of palm kernel meal varies greatly depending on its hulling degree and processing technology (similar to that of cotton meal). The most direct manifestation of using palm kernel meal to replace some corn is that the feeding effect is unchanged, but the feed cost is greatly reduced, and the competitiveness of animal products in the same industry is significantly improved. However, it is about 400 yuan cheaper than corn per ton. With the rapid rise of corn prices in northern and Northern China and the long-term downturn of animal product prices, some large and medium-sized feed enterprises must do everything possible to reduce costs in order to survive. Therefore, the use of palm kernel meal instead of some corn has become the s-choice product.

Functional components of palm meal fermented by roughage degrading agent

Here Z it is worth mentioning that the oligosaccharides produced after the degradation of palm meal, such as low molecular mannan oligosaccharides, are low molecular products after the decomposition of mannan in the fermentation process of roughage degrading agent, and glucogalactooligosaccharides. These small molecular oligosaccharides can effectively improve the disease resistance of animals. The mechanism is: (1) it preemptively combines with pathogenic bacteria (bacteria with type 1 pili, such as Escherichia coli, Salmonella, Vibrio cholerae, etc.), Blocking the adhesion between the pathogen pili and the intestinal epithelial receptor, thus preventing the pathogen from colonizing in the intestine and eliminating its pathogenic effect; (2) As an immune regulator, it stimulates the host to produce non-specific immunity and enhances the disease resistance; (3) Do not provide nutrition for pathogenic bacteria, making them hungry and unable to survive; (4) It has a strong adsorption on mycotoxins, which can greatly reduce the immunosuppressive and toxic effects of mycotoxins in feed.

Method of feeding animals with degraded fermented palm meal

The protein content of the palm meal fermented by the above method is about 17%, the digestibility energy is about 2.7 megacalories / kg, and the metabolic energy is about 2.4 megacalories / kg. It is recommended that the amount used in the animal diet be 20-40%, the small value for young animals and the large value for adult animals. The specific feeding amount is subject to the observation in practice. If the animal adapts, the amount can be increased slowly, otherwise, the amount can be appropriately reduced.
