Problems solved by technology

The current weaning method in which the mother and child are directly separated, on the one hand, it is difficult to accurately grasp the forage intake of the calf, and at the same time, the calf is severely stressed, resulting in frequent diseases during the weaning stage, which not only affects the investment cost, but also affects the health of the calf Cultivate survival rate

Abstract

The invention provides a shed capable of realizing accurate supplementary feeding and stress-free weaning for drylot feeding of a calve breastfed by a cow. An isolation door is arranged between a cow pen and a calve pen, so that the calve can freely pass to enter; the shed is characterized by comprising one group of cow-calve pen at least formed by the cow pen and the calve pen; the cow cannot enter the calve pen from the isolation door. According to the cattle shed, semi-isolation between the cow and the calf is realized, the calve in a suckling period can get close to the cow anytime to be breastfed anytime, and can enter a calve movement area anytime to take forage special for the calve, breastfeeding and supplementary feeding by the forage can be performed at the same time, and the normal growing development of the calve is ensured; the cow cannot enter the calve movement area and is separated from the calve, so that the daily supplementary feeding forage intake of the calve can be accurately measured and a suitable weaning period is determined, stress circumvention and safe weaning are realized, and the accurate feeding of the calve and later efficient production of the calve can be favorably realized.

Description

technical field [0001] The invention relates to a cowshed, in particular to a cowshed capable of realizing precise supplementary feeding and stress-free weaning of calves fed with a mother. Background technique [0002] The beef cattle industry is still a weak industry in my country's agricultural production or animal husbandry production. Especially as a large animal, the calving interval is long, and it is a single-born animal. Therefore, expanding the breeding of beef cattle, increasing the calving rate of cows, and improving the survival rate of calves are the key links for the sustainable development of the beef cattle industry. The breeding and calving of cows and the cultivation of calves during weaning are the key stages of group breeding. Long-term breastfeeding of calves leads to delayed estrus or inconspicuous performance of postpartum cows, which hinders normal reproductive performance, seriously affects the breeding benefits of breeding cows, and also dampens ...
