In the fall, the cattle's farming method is changed from grazing to feeding, and farmers need to make rough reserves.
Reserve
Use grass, corn, rice straw and silage, yellow storage, micro-storage, ammoniation and other technologies combined production. At present, corn whole plant silage not only has low nutrient loss (usually less than 15%), but also has a long preservation time, and it can maintain the juiciness. After fermented by lactic acid bacteria, the palatability is improved, and it is a good thick green for fattening beef cattle. Silage corn stalks It is called yellow storage; micro storage refers to adding anaerobic fermentation with high-efficiency active starter during the silage process. At present, the most widely used is the cellulose decomposing bacteria. Micro-storage can make silage better; ammoniating is mainly aimed at Straw, wheat straw and other crop stalks with lower water content and higher lignin are alkalized by spraying a certain amount of ammonia. The ammoniated straw is yellowish-brown, shiny, with a scent, soft texture, increased Palatability, but ammoniated ammonia must be treated, otherwise it is easy to cause ammonia poisoning beef cattle. These treatments increase the intake of straw by beef cattle and also increase the supplementation of crude non-protein nitrogen sources.
In addition to the crude reserves, it is also necessary to make fine reserves, including reserves of energy and protein. Energy is mainly corn; protein can be replaced by rapeseed cakes and cottonseed meal, which are relatively cheap; in addition, some additives, such as tantalum bricks, must be reserved to supplement nutrient deficiencies and prevent deterioration of quality. Palatability and utilization increase beef disease resistance, promote normal growth and accelerate growth.
Timely restocking
At the end of the fall, some large-scale grazing areas ended the grazing period. With the restriction of forage, the yaks that were born in that year needed to be treated. At this point, both in terms of price and quality, it is more appropriate for the breeding farms to purchase calves. In addition, for a fattening farm that purchases beef cattle from a long distance, it is also necessary to pay attention to the transport stress syndrome of cattle, that is, “Corrosive Lung Diseaseâ€. The following measures can be taken: Please help experienced people to help select cattle and do not rush to load the car. Observe firstly; avoid double-decked vehicles that are not shelter from wind and rain, and ensure cattle's drinking, feeding and calming during the journey to avoid cows lying down; protect cows from drinking water and salt after landing and do well in cold protection, cooling and gradual material changes. Nutrition, disinfection and isolation work; selection of drugs, reasonable formula, timely and adequate control of diseased cattle, early elimination of heavy cows.
Attention cowshed ventilation
Beef cattle do not affect the growth rate at temperatures of 0°C to 4°C. However, many cattle farms are now paying too much attention to the insulation of cowsheds to make the cowhouse highly humid. When the barn's humidity exceeds 70%, the growth rate of the cattle will decrease. Therefore, ventilation facilities need to be taken into consideration when building the barn. In addition, to ensure that cattle have sufficient light, the cattle can be pulled out of the house for natural light in clear weather; cattle are fed in full feed during autumn and winter, the herd breeding density increases, the risk of disease transmission increases, and ventilation can be to a certain extent Reduce the incidence of cattle disease.
Control acidity
The pH value of silage, yellow storage, etc. after fermentation is generally around 5.0, and acetic acid and lactic acid are generated during the fermentation process, which will make the silage acidity too high. Silage with too high acidity not only reduces palatability, but also has a corrosive and irritating effect on the teeth and gastrointestinal tract of livestock. Appropriate amount of urea can solve the problem of high silage acidity, and it can also increase the protein content in silage. Distillers grains, pomace fermented products and other acidity are also large. If these beef cattle are used for long-term fattening, the cattle will have unpleasant symptoms such as hair coke and tight skin. At the same time, they have a great influence on the quality of beef. In this case, a certain amount of baking soda can be added to the essence for feeding.
