Total mixed ration suitable for south and capable of improving milk yield and milk quality of lactating dairy cow and preparation method of total mixed ration

Abstract

The invention discloses a total mixed ration suitable for the south and capable of improving the milk yield and the milk quality of a lactating dairy cow. The total mixed ration is prepared from the following raw materials in percentages by weight: 16.22-23.75% of a concentrate feed for the dairy cow, 20-24.32% of composite silage, 22.5-27.03% of Chinese wildrye, 5.41-6.25% of alfalfa hay and 27.03-27.5% of wine dregs. The invention further provides a preparation method. The total mixed ration has the beneficial effects that the preparation method of the composite silage suitable for the south is provided and the addition amount of concentrate and forage is the optimal proportions at different production stages of the lactating dairy cow; crop by-products for preparing the composite silage are wide in source and low in cost, resource utilization of subsidiary crops and peel residues can be achieved to the maximal extent, the nutrient value and the palatability of the daily ration are improved, the milk yield and the milk quality of the lactating dairy cow at various production stages are improved to 12.57%, and the butter-fat percentage, the milk protein rate and the milk density are improved by 6.53%, 1.59% and 0.09% separately.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a fully mixed ration suitable for the south that can improve milk production and milk quality of lactating dairy cows and a preparation method thereof. Background technique [0002] Total Mixed Ration (TMR) technology refers to the formula of full-price nutritional ration for dairy cows designed according to the nutritional requirements and feeding purposes of dairy cows in different growth and lactation stages, in accordance with the nutritional regulation technology and the principle of multi-feed matching. Feed processing and feeding technology in which , concentrate, green feed, juicy feed, minerals, vitamins and other additives are uniformly mixed together through specific equipment and feed processing technology for dairy cows to eat. The traditional feeding method is to feed the concentrate, coarse material, auxiliary material and green and juicy material separate...

AI Technical Summary

Problems solved by technology

The traditional feeding method is to feed the concentrate, coarse material, auxiliary material and green and juicy material separately, which not only consumes manpower and labor, but also cannot ensure that each cow can eat feed in a balanced manner, which will easily lead to abnormal rumen function and nutritional imbalance, shortening the life of the cows. Lifespan, affecting milk production and milk quality in lactating cows

At present, TMR technology, as the most effective dairy farming technology, has developed rapidly in the world. In developed dairy countries such as the United States, Canada, and Israel, TMR feeding technology has been widely used. In Japan and South Korea, the penetration rate of TMR feeding technology has also reached At present, 36.8% of the large-scale cattle farms in my country have adopted TMR feeding technology. In the hot and humid south, Nanning, Guangxi has only started to use it in recent years, but this technology has not been applied in other cities such as Liuzhou.
