Fermented daily feed with low fine fodder content for ruminant domestic animals and preparation method thereof

Abstract

The invention discloses a fermented daily feed with a low fine fodder content for ruminant domestic animals and a preparation method thereof. The feed comprises the following raw materials in parts by weight: 25 to 45 parts of straws, 5 to 15 parts of forage grass, 5 to 15 parts of protein forage, 20 to 40 parts of energy forage, 7 to 17 parts of food processing byproduct, 0.2 to 0.4 part of trace element and vitamin premix, and 1 to 3 parts of mineral substance. The preparation method comprises the following steps: mixing the raw materials mentioned above to obtain a mixture; adding water to adjust the water content to 40-50%, and transferring the mixture to a sealed container to carry out fermentation for at least 14 days so as to obtain the fertilizer. Abundant crop straws and food processing byproducts are taken as the main raw materials of fertilizer, and the produced daily fertilizer for ruminant domestic animals has the advantages of comprehensive nutrients, high digestibility, good palatability, and good aerobiotic stability, is suitable for all ruminant domestic animals, and is very practical.

Description

technical field [0001] The invention belongs to the field of livestock feed processing, in particular to a low-concentrate fermented ration for ruminant livestock and a preparation method thereof. Background technique [0002] According to statistics, my country's annual output of crop straw is about 700 million tons, accounting for about 30% of the world's total annual output of straw, which is a huge potential feed resource for the development of herbivorous livestock. However, the crop straw is rough and hard, and its nutritional value is not high. If it is directly used as feed for ruminants, it has low digestibility, poor palatability, and is difficult to effectively use. Recently, the utilization rate of my country's straw is only 33%, and the utilization rate of the part after technical treatment is less than 3%. [0003] Food processing by-products generally have high moisture content, are not resistant to storage (especially in summer), and are prone to rancidity. ...

AI Technical Summary

Problems solved by technology

However, the crop straw is rough and hard, and its nutritional value is not high. If it is directly used in the feed of ruminants, the digestibility is low, the palatability is poor, and it is difficult to effectively use it.

Recently, the utilization rate of my country's straw is only 33%, and the utilization rate of the part after technical treatment is less than 3%.

However, TMR is generally prepared and used immediately, and it is not easy to store for a long time

Studies have found that TMR generally begins to deteriorate within 24 hours after preparation, which not only reduces the palatability and causes serious waste of feed, but also reduces the dry matter intake of feed and affects the production performance of livestock

At the present stage, the delivery of TMR is not yet able to achieve daily delivery. Therefore, in order to commercialize TMR and facilitate storage and transportation, certain packaging and storage treatments are required for it.
