Nutritional fermented palm meal and preparation method thereof

Abstract

The invention provides nutritional fermented palm meal and a preparation method thereof. The preparation method comprises the following steps: taking palm meal as a raw material, mixing the palm mealwith water, uniformly stirring, and performing treatment at 165 DEG C for 10 minutes; inoculating microbial strains according to the weight of the palm meal after treatment, and performing fermentation at 30-45 DEG C; and carrying out low-temperature drying after the fermentation is finished. In the fermented palm meal, the protein content is more than or equal to 12%, acid-soluble protein accounts for more than 8% of the protein content, the total acid content (calculated by lactic acid) is more than or equal to 0.6%, the neutral detergent fiber degradation rate is more than or equal to 12%,and the beneficial microorganisms of the product are more than or equal to 109CFU / g. The production cost is low, the fermentation process is easy to control, and the product quality is stable. The nutritional value of the palm meal and the bioavailability are improved, and the fermented nutritional feed is directly used and partially replaces concentrated feed and silage corn. The prepared fermented palm meal can be eaten by ruminants, the digestive absorption capacity of the ruminants can be improved, the micro-ecological balance in animal bodies can be adjusted, and the disease prevention and resistance capability of the ruminants can be enhanced.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a nutritionally fermented palm meal and a preparation method thereof. Background technique [0002] In recent years, due to the shortage of feed resources, research on new alternative resources has become a hot spot in the industry. Palm meal is a by-product of extracting palm oil from palm kernels. It is rich in resources and low in price. As a feed material, it also has the advantages of no anti-nutritional factors, no aflatoxin pollution, anti-oxidation, and good palatability, but its crude fiber content is high, and it has anti-nutritional factors such as mannan. The low utilization rate of crude protein and other reasons limit its wide application. [0003] If solid-state fermentation can be used to improve its nutritional performance and increase its scope of application, it will have great practical significance for alleviating the shortage of feed resources and maintaining th...
