Shelf cattle fast fattening technology

<

First, the shelf beef rapid fattening stage divided into general shelf cattle fast fattening takes about 120 days, can be divided into 3 stages, namely the transitional insect repellent period, about 15 days; fattening period, about 45 days (16th to 60th days); In the late finishing period, about 60 days (61 to 120 days). 1. Transient repellent period This period is mainly to let cattle familiar with the new environment, adapt to the new conditions of forage, eliminate the stress caused by the transport process, restore the body strength and weight of cattle, observe the health of cattle, stomach, drive Insects, deciding whether or not to cast bulls. Insecticides generally use avermectin, which can kill multiple parasites in vitro at the same time. The diet began to be dominated by coarser quality products that were not fed or fed less concentrate. As the strength of the cattle recovered, the concentrate was gradually increased, the proportion of refined coarse material was 30:70, and the level of dietary protein was 12%. If the shelf of the cows purchased is poor, compensatory growth can occur at this time, and the daily gain can reach 800-1000 grams. 2. The proportion of coarse grains in the diet during the early finishing period gradually increased from 30:70 to 60:40. The amount of concentrate can be fed with 1 kg of concentrate per 100 kg of body weight; raw material can be fed freely. The main task of this period is to allow cattle to gradually adapt to the condiment diet to prevent diseases such as bloating, diarrhoea and acidosis, and not to drag the time too long. The general transition period is 10 to 15 days. The daily gain in this period can reach more than 1000 grams. 3. The proportion of refined coarse grains in the diet during late finishing can be further increased to 70 to 80:20 to 30. In the production, 1.1 to 1.5 kg of concentrate can be fed per 100 kg of actual body weight of the cow. The raw material can be eaten freely, and the daily weight gain can reach 1200-1500 g; fattening in this period is often called as fattening. In order to allow the cow to eat a large amount of concentrate, the number of feedings can be increased during this period, and the original two feedings can be increased to three times to ensure sufficient drinking water.
