A mutton sheep fattening ftmr based on micro-storage rice straw and its preparation method

Abstract

The invention relates to a mutton sheep fattening FTMR based on micro-storage rice straw and a preparation method thereof, belonging to the field of animal husbandry feed processing. Make full use of local straw resources, and add lactic acid bacteria to make wrapped micro-storage straw in the field for preservation. Then, according to the nutritional needs of lamb fattening, the micro-storage rice straw is unpacked and crushed in the TMR processing plant, combined with other feed materials, compound bacterial agents are added, and after a second wrapping and fermentation, a second-stage lamb fattening fermentation full-mixed day is made. Grain can meet the two stages of weight gain during the fattening period: 15-30kg and 31-45kg respectively, and realize the industrialized production of fattening sheep in southern agricultural areas and under the condition of lack of forage resources. With the application of the invention, the average daily gain of Boza goats during the fattening period can reach more than 190g / d, and the direct cost of the diet is less than 1.5 yuan based on the current market price.

Description

1. Technical field [0001] The invention relates to a mutton sheep fattening FTMR (fermented total mixed ration) based on micro-storage rice straw and a preparation method thereof, which belongs to the field of animal husbandry feed processing and is suitable for intensive whole house feeding production of mutton sheep. [0002] 2. Technical background [0003] my country is a big producer of straw, with an annual output of nearly 800 million tons of straw, and its possession of resources ranks first in the world. However, in addition to 30% used as fuel, 25% used as feed, 6%-7% directly returned to the field, and 2%-3% used as raw materials for industrial production, there are still 35% of the remaining 260 million tons of straw that have not been rationally utilized . During the harvest season in summer and autumn, straw burning has not only become the bottleneck of rural environmental protection, but has even become an important factor that affects the urban environment. ...

AI Technical Summary

Problems solved by technology

And this method can no longer adapt to the requirements of large-scale and intensive production of modern mutton sheep.

The main problem is that it is difficult to ensure a suitable and stable ratio of fine to coarse feed, and at the same time, because the dynamic balance of digestion and metabolism in the rumen is disrupted, the digestibility of crude fiber is reduced, which affects the production performance of mutton sheep

But TMR also has some problems in the actual application process, especially in order to ensure the mixing uniformity of the diet and prevent animals from being picky eaters, it is often necessary to add moisture in the stirring process (the moisture content of the feed is usually controlled at 40%-50%), so that Make TMR easy to rot and deteriorate, resulting in the loss of feed nutrients and even animal diseases

Moreover, small and medium-scale sheep farms and even scattered breeding will exist in my country for a long time. The cost of purchasing machinery and equipment required for TMR feed production is still far from being affordable, and the produced fully mixed rations cannot be stored for a long time, and they will deteriorate within 24 hours. TMR diets are out of reach in many cases
