The fattening period is a crucial period for fattening beef cattle. The key points for feeding and management are to raise the nutritional level. The second is to attach importance to the feeding strategy and the third is to strengthen daily management. With these three points in mind, beef cattle production can easily achieve the desired results. 1, improve nutrition levels. If you are producing ordinary beef, you can choose shelf cattle or adult cattle, using short-term fat fertilizer method, after 7 to 10 days of preparation and 10 to 20 days of transition, you can increase the level of concentrate to 40% of the diet About 50%, until slaughter. In order to strengthen the effect of fattening, it is advisable to add mixed concentrate at the later stage to mix the concentrate formula: 72% cornmeal, 8% wheat bran, 1% bone meal, 1% salt, 1% urea, 2% additive, and daily feed of mixed concentrate The amount fed is preferably 1% of body weight. If high-grade beef is produced, it is mainly to purchase shelf cattle. The fattening period should be appropriately extended and the concentration of concentrates should be continuously increased. The specific arrangement is: 1 to 20 days, the proportion of concentrates in the ration is 55% to 60%, 21 to 50 Day, the proportion of concentrate in the diet is 65% to 70%, 51 to 80 days, the proportion of concentrate in the diet is 75%, 81 to 100 days, the proportion of concentrate in the diet is 80% to 85% . 2, emphasis on feeding strategy. One day more meals slowly transition. From the coarse-grained diet to the concentrate-type diet, the appetite of cattle is obviously enhanced. If it is not controlled, the feed intake will naturally increase significantly. This can easily lead to digestive diseases, which may cause abdominal bulge, diarrhea, and rumen accumulation. Symptoms, severe cases and even death from acidosis. Therefore, in the early stage of feed conversion, it is necessary to pay attention to controlling the amount of concentrate feed, adopt a multi-day meal system, and feed one to four fine meals a day. After 6 to 7 days of transition, wait until the cow has adapted. , you can change to a free way of feeding, feed can stay overnight in the feed tank. Pay attention to supply enough water. Under normal circumstances, a cow needs 5.5 kg of water to feed 1 kg of feed dry matter. If the temperature is higher during the season, the amount of drinking water will increase. Therefore, it is necessary to ensure that cows can drink clean drinking water at any time during the fattening period. Conditional large-scale farms can set up automatic water supply equipment. Household farmers should supply water 3 to 4 times a day. Feeds are finely processed. In addition to concentrate feed, the diet of fattening cattle must have roughage such as hay and straw. The composition of roughage should not be single, and should be diversified as much as possible. Attention should be paid to improving the palatability of feeds. Careful removal of impurities by means of short, sifting, etc., is not recommended for the feeding of beef cattle after crushing the roughage. It is necessary to adopt the principle of feeding after the first rough, to promote the cattle to eat more. Appropriately feed the supplement. Feed additives commonly used in beef cattle production, in addition to nutrients, mainly rumen, antibiotics, weight gain agents, of which the most commonly used rumen. Ruminin, also called monensin, is a fermentation product of Streptococcus sobrinus, which can reduce protein degradation in the rumen, inhibit the production of acetic acid in the rumen and ammonia production, increase the amount of protein reaching the stomach, and increase the utilization of nitrogen. Improve feed remuneration. The daily dosage of each cow is 180 to 260 mg. 3, to strengthen daily management. Observe the observation. During the fattening period, the husbandry and management personnel must be diligent in observing the feeding, rumination, drinking desire, defecation, and mental status of the cattle to prevent and early discover the symptoms of gastrointestinal diseases. During the 2 to 3 days of dietary changes, special attention must be paid to the ruminants and defecation of cattle. If any abnormalities are found, the necessary treatment measures must be taken promptly. Brush fur. Brushing the fur will not only help remove dust, parasites, and metabolic waste from the body surface, but also promote blood circulation, speed up metabolism and improve fattening effect. Soft brush is often used to brush along the direction of the hair, 1 or 2 times a day. Do a good job of the environment. When a large group feeds, each cow has an area of ​​4 square meters. The cowshed should be dry and clean, and it should be kept warm in winter and heatstroke in summer. Clean stools on a daily basis, and utensils such as food troughs should be regularly cleaned and disinfected. Keep the environment quiet, prevent all kinds of noise and prevent animal harassment. Tethering can be used to minimize cattle activity during the finishing period. When the weather is fine in winter, feed cows to the sun in time after feeding each day.
