Problems solved by technology

However, this traditional method cannot meet the requirements of large-scale and intensive production of modern mutton sheep.
The main problems are: it is difficult to increase the dry matter intake, it is difficult to ensure the feed with 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, resulting in sheep Production performance is limited and reproductive performance is also affected

Embodiment Construction

[0029] (1) Raw material preparation

[0030] Fresh tofu dregs: a by-product of processing tofu, soymilk or soymilk with soybeans as raw materials. It is rich in fiber, protein, fat, isoflavones and vitamins, etc., and has good nutritional value. According to the test, the dry matter content of fresh bean curd residue is 15%-25%, crude protein 10%-15%, crude fiber 20%-25%, crude fat 1%-2%, calcium 0.4%-0.7%, phosphorus 0.2%- 0.4%. The raw material is available in large quantities throughout Jiangsu.

[0031] Soybean stalks: Refers to the remaining plant parts after soybeans are harvested. In the past, most of them were dried and used as fuel. The crude protein content of soybean straw is 7% to 9%, rich in cellulose, hemicellulose and pentosan, which can be digested and utilized by cattle and sheep with the help of rumen microbial fermentation. Soybean stalks are used as feed in large quantities and from a wide range of sources.

[0032]Premix: It is a finished product form...

Abstract

The invention relates to a total mixed ration for promoting the onset of puberty of replacement ewes, which belongs to the field of feed processing in zootechny. According to the nutrient requirement of replacement ewes, the invention sufficiently utilizes the local rich and cheap unconventional feed resources, such as soybean curd residue and soybean straws, added with functional nutrient substances to prepare the total mixed ration. The total mixed ration disclosed by the invention can meet the requirement of growth and development at the two stages of 15kg to 25kg and 26kg to 35kg, achieving suitable body weight for the onset of puberty, and moreover, the total mixed ration can increase the reproductive performance of replacement ewes and promote the estrus of the replacement ewes, thus achieving the objective of advancing the puberty of the replacement ewes.

Description

1. Technical field [0001] The invention relates to a fully mixed ration for promoting the initiation of puberty of gilt ewes. It belongs to the field of animal husbandry feed processing and is suitable for large-scale and intensive whole-house feeding production of mutton sheep. 2. Background technology [0002] The start of puberty is an important sign of the reproductive ability of gilts, and the main goal of raising gilts is to start puberty in a timely manner and have a good follicle development state. The reproductive performance of ewes is mainly regulated by the reproductive axis. The energy reserve status of the body can significantly affect the functional activity of the reproductive axis. Studies have shown that during the breeding period of gilts, overfeeding or undernutrition will delay the onset of puberty, but there is no standard for how to determine "overfeeding" and "undernutrition". The specific mechanism by which diet affects the onset of puberty in gil...
