The suitable temperature in the autumn, rich pasture and crop stalks are the best seasons for fattening beef cattle. It is very important to strengthen the raising and management of this period to improve the benefit of raising cattle. Specifically, the following three points should be made.
Improve nutrition
If ordinary beef is produced, ordinary beef can be purchased. Shelf or adult cattle can be purchased. Short-term fattening method is used. After 7 to 10 days of preparation and 10 to 20 days of transition, the concentrate level can be increased to the level of the diet. About 40% to 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.
For the production of high-grade beef, if high-grade beef is produced, it is mainly to purchase shelf cattle. The fattening period should be appropriately extended, and it is advisable to continue to increase the fine material level. The specific arrangement is: 1 to 20 days, the proportion of concentrate in the diet is 55% to 60%, 21 For ~50 days, the proportion of concentrates in the diet is 65% to 70%, 51 to 80 days, the proportion of concentrates in the diet is 75%, 81 to 100 days, and the proportion of concentrates in the diet is 80%~ 85%.
Pay attention to feeding strategy
When one-day meals transition from coarse-grained diets to concentrate-feeding diets, the appetite of cattle is significantly increased. If uncontrolled, feed intake will naturally increase significantly. This can easily lead to digestive diseases, bloating, and diarrhea. , rumen plot food and other symptoms, severe cases and even death due to acidosis. Therefore, in the early stage of feed conversion, we must pay attention to controlling the amount of concentrate feeding, adopt a multi-day meal system, and feed one day of concentrates 4 to 5 times, after 6 to 7 days of transition, after the cattle are adapted , you can change to a free way of feeding, feed can stay overnight in the feed tank.
Adequate drinking water In general, when a cow feeds 1 kilogram of dry matter for feed, it needs 5.5 kilograms of drinking water. It is necessary to ensure that the cow 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.
Diversification of feeds 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.
Feed additives Feed additives commonly used in beef cattle production, in addition to nutrients, mainly rumen, antibiotics, weight gain agents, the most commonly used is 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 180-260 mg.
Strengthen day-to-day management
Observe that during the period of fattening, 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 should be paid to the ruminants and defecation of cattle. If any abnormalities are found, it is necessary to take necessary measures in time.
Brushing fur is not only beneficial to clear body surface dust, parasites, metabolic waste, but also promote blood circulation, speed up metabolism, improve fattening effect. Soft brush is often used to brush along the direction of the hair, 1 or 2 times a day.
In order to do a good job in raising large groups of environment, it is advisable for each cow to have an area of ​​4 square meters. The cowshed should be dry and clean, and the stool should be cleaned in a timely manner. The utensils such as the trough 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.
