Short-term fattening method for beef cattle with 50-day net weight gain of 400 jin

How to make beef cattle fat and strong, fresh meat and net gain of about 200 kg in 50 days is a very concerned problem for cattle farmers. If the cost of raising cattle is reduced, the benefits will be better. The short-term fattening technology of this beef cattle is introduced as follows:

beef cattle

1. Do a good job of insect repellent

Cattle are parasitized with roundworm, nematode, schistosomiasis, tapeworm, cysticercus and other parasites, which seriously affect the growth and development of beef cattle. Before fattening, the parasites in and out of beef cattle must be eliminated first. Can choose 150-250 broad-spectrum, high-efficiency, low-toxic propimidazole direct irrigation, can also be based on each kilogram of body weight with 20-30 mg of sulfur bis dichloride powder, mixed in feed, administration, have better results. For ectoparasites, only a 1 -3% aqueous solution of trichlorfon needs to be rubbed on the affected part.

2. Feed supplement.

The emphasis is on supplementing feed mixed with urea.

The ration formula is: corn 500- 600g, rice bran 800- 1000g, urea 100- 120g, calcium carbonate or bone meal 50g, salt 50g. The above is the reference feeding amount for each cow for 1 day, which is fed in three times: early, middle and late. Feed first at each feeding time, and let beef cattle drink enough water at an interval of 1 hour.

The key points are: the daily feed amount of concentrated feed for each beef cattle should be increased from 750 g to 1000 g, urea from 100-120 g to 150 g (when ammoniated feed is used, urea is not added), and sufficient high-quality green, hay or nitrogenated straw feed should be provided for beef cattle to eat freely, so as to be full. If there are conditions, at 10 o 'clock every night can also be added to feed the right amount of night grass, conducive to fattening. In addition, in order to create a good environment, the eliminated beef cattle are only raised with short ropes of about 1 meter, fed with troughs and pots, and the fodder should be cut into short sections of 3-5 cm, which can limit the movement of beef cattle to the maximum extent and reduce physical consumption.

Third, urea should be used to ammoniate straw feed.

The method comprises the following steps of: cutting the straws into short sections within 15cm, dissolving lime and urea in water according to the proportion of straw, water, urea and lime of 100:50:4:3, pouring the lime and urea on the straws, mixing uniformly, covering the straws with a thin film, sealing the edges with thin mud, and completing ammoniation in only 2-3 weeks. Feed beef cattle in this way, feed intake, digestibility increased by 20%, crude protein content increased by 1-2 times, the effect will be better.
