Feed not fattening Beef cattle is blocked from fattening the main points of Green roughage for Beef cattle

Control the acidity of feed. The pH value of fermented feed such as silage and yellow silage is about 5.0, and acetic acid and lactic acid are produced in the process of fermentation, which makes the acidity of silage too high. The silage with high acidity is not only palatable, but also corrosive and irritating to the teeth, stomach and intestines of beef cattle, which is disadvantageous to eating. proper addition of urea can solve the problem of high acidity of silage and increase the content of protein in silage. Distiller's grains, fruit dregs fermented products and other acidity are also large, such as using these feeds to fatten beef cattle for a long time, it will affect the physique of beef cattle, cattle appear hair coke, skin tightness and other symptoms, the fattening effect is not ideal, at the same time, it has a great impact on beef quality, in this case, a certain amount of baking soda can be added to the concentrate feed.

Beef cattle

Beef cattle enter the autumn and winter, from grazing to house feeding, at this time need to carry on the roughage reserve. Roughage was produced by the combination of forage, rice straw, corn and silage, yellow silage, microsilage, ammoniation and so on. At present, the whole plant silage of corn has less nutrient loss (less than 15%), long preservation time, and can keep the feed juicy. After lactic acid bacteria fermentation, the palatability is improved, which is a good roughage for fattening beef cattle. Only silage corn straw is called yellow silage. Microsilage refers to the addition of highly active starter for anaerobic fermentation in the process of silaging. at present, cellulose decomposing bacteria are most widely used, microsilage can make the silage effect better, but this technology is not yet mature. Ammoniation is mainly aimed at rice straw, wheat straw and other crop straw with low water content and high lignin. By spraying a certain amount of ammonia water, the ammoniated straw is yellowish brown, shiny, has a kind of paste flavor, soft texture, and increases palatability. However, the ammoniated feed must be treated with ammonia, otherwise it is easy to cause beef poisoning. These treatments not only increased the feed intake of beef cattle, but also increased the non-protein nitrogen source supplement of roughage.

While storing roughage, it is also necessary to reserve concentrate fodder, including energy feed and protein feed. Corn is the main energy feed. Protein feed can use relatively low-priced rapeseed cake and cottonseed meal instead of soybean meal. In addition, it is necessary to reserve feed additives, such as licking bricks, to supplement feed nutrition deficiency, prevent feed quality deterioration, improve feed palatability and utilization rate, enhance disease resistance and accelerate growth of beef cattle.

In the process of fattening, pay attention to the ventilation of the barn. 0-4 ℃ does not affect the growth rate of beef cattle, but at present, many cattle farms pay too much attention to the heat preservation of the barn, which makes the barn have high humidity. When the humidity exceeds 70%, the growth rate of beef cattle decreases, so ventilation facilities should be considered when establishing the barn. In addition, it is also necessary to ensure that the beef cattle have sufficient light, which can be achieved through the construction of the barn, and the cattle can be led out of the barn for natural light when it is sunny. In addition, in autumn and winter, beef cattle enter full feeding, the feeding density increases, the epidemic disease transmission rate increases, ventilation can reduce the incidence of beef cattle to a certain extent.

The beef cattle will be mended in time. In autumn and winter, the grazing period has ended in some large grazing areas, and calves born in that year need to be treated due to the restriction of forage feed. At this time, no matter in terms of price or quality, the fattening farm is more suitable to buy calves. In addition, for fattening farms that buy beef cattle from a long distance, attention should be paid to cow transport stress syndrome, that is, "rotten lung disease". Measures should be taken: select experienced cattle, do not rush to load, observe and recuperate for several days; avoid double-decker vehicles; consider beef cattle drinking water, supplementary feeding, sedation, physical strengthening (such as Cottzhuang) and lying down. Drinking water on the ground, supplying salt, preventing cold, cooling, gradually changing materials, strengthening nutrition, disinfection and isolation; select good drugs, reasonable formula, timely and sufficient control of sick cattle, and eliminate seriously sick cattle as soon as possible.
