Milk goat fermented total mixed ration based on fresh green forage

Abstract

The invention provides milk goat fermented total mixed ration; after fresh green forage with high water content is mixed with other milk goat feed components, the anaerobic fermentation is implemented to prepare the milk goat fermented total mixed ration, wherein the mass ratio of the fresh green forage with high water content to the other milk goat feed components ensures that the total water content is 40-50% after mixing. The milk goat fermented total mixed ration uses the fresh green forage as the main raw materials to be reasonably matched with such components as energy feed, protein feed and feed additive premix; the proper water content is controlled through regulating the matching ratio of feeds; then the anaerobic fermentation is implemented to prepare the total mixed ration product. The FTMR (Fermented Total Mixed Ration) restrains the breeding of microorganisms mainly through causing the physiologic dry of the microorganisms and the anaerobic fermentation, so that the storage resistance of the FTMR can be improved, the storage time is prolonged, the source of the green forage is widened, the fermentation degree of the high-quality green forage is prominently reduced, and the nutritional value of the green forage is effectively preserved.

Description

technical field [0001] The invention belongs to the field of animal husbandry feed processing, and in particular relates to a fermented total mixed diet for dairy goats based on fresh green feed and a preparation method thereof. Background technique [0002] Green feed refers to succulent feed with natural moisture content ≥ 45%. It is named for its rich chlorophyll, mainly including natural forage grass, artificial cultivation forage grass, green forage crops, crop straw vines, leafy vegetables, non-starch root melons species, branches and leaves, and aquatic plants. There are many kinds of green fodder, wide sources, high yield, and rich nutrition, especially containing more protein, calcium, phosphorus, vitamins and other nutrients, which can improve the growth and development of animals, improve the quality and output of livestock products, and are well-known by people. As "green energy", it is especially important for lactating livestock such as dairy cows and dairy go...

AI Technical Summary

Problems solved by technology

However, when drying hay, at least 50% of the nutrients will be lost during the drying process, and it is easily affected by seasons and climatic conditions.

Although silage is the most effective way to preserve the nutritional value of green feed, conventional silage often has the following defects, which limits its application: ① Conventional silage mainly uses the carbohydrates in the feed to produce lactic acid through the fermentation of lactic acid bacteria, which reduces the pH of the feed to below 4.2, thereby inhibiting the growth of various microorganisms and achieving the purpose of long-term preservation of feed

This method is only suitable for raw materials such as gramineous crop straw and grass forage with high sugar content, while high-quality leguminous forage (alfalfa, sweet clover, etc.) and crop vines (peanut seedlings, sweet potato vines, etc.) The amount of silage is low, which cannot meet the needs of the growth of lactic acid bacteria, and it is difficult to succeed in conventional silage; ②The pH of conventional silage is low, generally between 3.8 and 4.2, and it is not easy to feed in large quantities. If the feeding amount exceeds 2 / 3 of the roughage , it is easy to lead to a drop in rumen pH, which will cause a drop in feed intake and certain digestive and metabolic disorders, such as acidosis, reduced milk fat rate, etc.; It is easy to produce secondary fermentation and cause feed to rot; ④The water content of conventional silage is generally between 60 and 70%, which often limits the feed intake of dry matter and leads to a decline in production performance

The effective way to solve the above problems is semi-dry silage (low-moisture silage), but low-moisture silage often needs to let the silage raw material wither in the field, reduce the moisture content to 40-50%, and then silage according to the general method. Light irradiation and mechanical loss cause leaves to fall off and aggravate the loss of nutrients, and it is not easy to mechanize operation, which reduces the processing efficiency
