Ewe stage nutrition regulation ration and modulation method thereof

Abstract

The present invention discloses a ewe stage nutrition regulation ration, which comprises the following raw materials, by mass, 1.2-1.6 parts of sodium selenite, 0.9-1.2 parts of potassium iodide, 1.1-1.5 parts of cobalt chloride, 0.7-1.0 part of copper sulfate, 1.2-1.7 parts of zinc sulfate, 1.4-3.1 parts of ferric sulfate, 1.0-1.6 parts of manganese sulfate, 0.8-1.1 parts of VA, 0.4-0.6 part of VD, 0.8-2.0 parts of VE, 2.0 parts of gypsum, 20 parts of zeolite, 63.6-67.5 parts of rice hull, 145-160 parts of gravy salt, 90-120 parts of calcium hydrogen phosphate, 15-35 parts of baking soda, 0-45 parts of magnesium oxide, 1150-3600 parts of corn, 0-490 parts of soybean hull, 150-480 parts of bran, 210-1040 parts of soybean meal, 229-720 parts of sunflower cake, 205-710 parts of palm meal, 285-890 parts of corn distiller's grain protein, 210-640 parts of sesame cake, 12000-27600 parts of yellow corn silage, 3800-10800 parts of hay, 3800-7800 parts of corn straws, and 1700-4450 parts of rice bran. The modulation method comprises: preparing trace elements, vitamins, and the like into a premix; mixing gravy salt, corn, soybean meal, and the like with the premix to prepare into a fine material mixed material; uniformly mixing yellow corn silage and the like with the fine material mixed material to obtain the total mixed ration. With the present invention, nutrition requirements of ewe at different stages are met, breeding efficiency is improved, and feeding cost is reduced.

Description

technical field [0001] The invention relates to the fields of feed production technology and breeding technology, in particular to a ration for ewe staged nutrition regulation and a preparation method thereof. Background technique [0002] With the deepening of the implementation and work of policies such as returning farmland to forests, returning farmland to grassland, and enclosing natural grasslands, there are fewer and fewer lands available for grazing in agricultural areas, semi-agricultural and semi-pastoral areas, and pastoral areas, and breeding accounts for more than 60% of the number of sheep. Half-feeding ewes has become inevitable. Due to the lack of breeding technology in the house, the cost of breeding ewes in large groups is greatly increased, especially for ewes with a reproductive rate lower than 100%, the investment in feeding for one year far exceeds the income. Many local farmers have massacred ewes, resulting in a decrease in the number of breeding ewe...

Problems solved by technology

Due to the lack of breeding technology in the house, the cost of breeding ewes in large groups is greatly increased, especially for ewes with a reproductive rate lower than 100%, the investment in feeding for one year far exceeds the income. Many local farmers have massacred ewes, resulting in a decrease in the number of breeding ewes in recent years, the purchase price of lambs has continued to rise, and the supply of fattened lambs has also decreased accordingly

After the breeding ewes are house-raised, the annual forage cost accounts for 70% of the total investment. Many farmers use one kind of diet formula all year round. In addition, the coarse feed is not processed and the quality is poor, and they mainly rely on concentrated feed. To maintain the production of ewes, this will inevitably increase the use of feed, which is contrary to the purpose of developing grain-saving animal husbandry at this stage in our country

In addition, when ewes are in different reproductive physiological periods, their nutritional requirements are also different. Their nutritional requirements are lower during the empty pregnancy period and early pregnancy, while their nutritional requirements are higher during late pregnancy and lactation periods. If the ewes are fed with the required amount of nutrients, the ewes will be too fat, and the fat accumulation will be too high, which will affect the estrus of the ewes; if the nutrition is too high in the early pregnancy, it will cause the early death of the embryo and reduce the reproduction rate; if it is fed at a low nutritional level all year round, Due to the poor body condition of the ewes, it also affects the estrus and breeding of the ewes, and the lack of nutrition in the late pregnancy, resulting in weak vitality of newborn lambs and low survival rate of lambs
