Young cattle fattening
Young cattle fattening mainly utilizes the characteristics of fast growth of young cattle. After calf weaning, the calf is directly transferred to the fattening stage, and feeds with high levels of nutrition are subjected to continuous strength fattening. The cow is slaughtered before the age of 2 years old and the slaughter weight is 550. More than kilograms. This type of beef is fresh and juicy, with less fat and good palatability.
Grazing grazing supplementation intensity fattening method: calves after weaning feeding, to the spring of the following year combined with grazing appropriate feed concentrate. This type of fattening method uses less concentrate, and consumes 2 kg of refined material per 1 kg of weight gain, but it has less daily weight gain. The average daily weight gain is within 1 kg, and the 15-month-old body weight is 300-350 kg. The age is 400-450 kg. This method is suitable for semi-agricultural and pastoral areas. For grazing supplemental feeding, it is necessary to pay attention not to add feed immediately before or after the harvest, but to supplement the feed several hours after returning. When the weather is hot, you should go home early and return late, rest at noon, if necessary, night animal husbandry. When the supplement is coarse, straw is the main ingredient. The formula of the concentrate is as follows: 1~5 months, corn noodles 60%, oil residue 30%, wheat bran or rice bran 10%; 6~9 months, corn noodles 70%, oil residue 20%, wheat bran or rice bran 10%.
Silage corn-based fattening method: silage corn is a high-energy feed, protein content is low, generally not more than 2%. Feeding a diet that uses silage corn as its main ingredient requires a mix of 1.5 kg or more of mixed concentrate to achieve high daily weight gain. Using silage corn as the main fattening method, if the hay is glutinous rice, sand shanwang, red bean grass, pine cone herb or high-quality grass, if the content of soybean meal in the concentrate is more than 50%, the daily weight gain may be 1.2 kg. the above.
Hay-based fattening method: In areas rich in hay, autumn and winter can store a large amount of high-quality hay, which can be used for fattening hay. The specific method: let the cow eat hay randomly, and add 1.5 kg of fine material daily. The quality of hay plays a key role in the effect of weight gain. It is better to use the mixed legume and legume hay to feed, and it can also save the concentrate.
Shelf fattening
Shelf fattening, also known as post-stage fattening, refers to the feeding of yak after weaning, feeding for 18 to 30 months according to more extensive feeding conditions. When the weight of cattle is above 300kg, the fattening method is used to concentrate fattening for 3 to 4 months. Make full use of the cattle's ability to compensate for growth, slaughter after achieving ideal weight and lyrics. Grazing during the day in the summer, feeding at night, feeding a small amount of fine material, winter feeding all day, in cold areas with a plastic shed covered with plastic film. During the feeding stage, the feed is mainly straw and pasture, and a certain amount of distiller's grains and a small amount of rice bran and bean cake are properly added. This kind of fattening method has low cost, less amount of fine material, high economic benefit, and wide application. Shelf fattening cattle should pay attention to the following aspects:
1 week before cattle purchase, fecal matter should be removed from the cowhouse. After washing with water, the floor and walls of the cowshed should be disinfected with a 2% solution of pyrogenic alkali (sodium hydroxide), and the appliance should be treated with 0.1% potassium permanganate solution. Disinfect and wash it once with clean water. If it is an open barn, it should be shaded in summer and plastic film should be used in winter to keep it well ventilated to a temperature not lower than 5°C.
Should be selected Charolais, Simmental and other international breeds and local yellow cattle hybrid fertility fattening, requiring cattle 1 to 3 years old, large size, Pisuan soft, good lyrical, weighing more than 300 kg, healthy and disease-free.
Immediately after the cattle are placed on the shelf, they are dewormed. Commonly used deworming drugs include afrmedin, albendazole, trichlorfon, and levamisole. Should be fed at fasting cattle to facilitate drug absorption. After deworming, the cattle should be kept in isolation for 1 week, and the feces should be disinfected and decontaminated.
Deworming should be carried out after 3 days. The commonly used stomachic drug is artificial salt, and its oral dose is 60 to 100 grams per head.
Fattening cattle should use short lines to limit activities. The reins are 0.4 to 0.5 meters long, making cattle inconvenient. Feeding should be quantified regularly, first coarsely after finishing, and less frequently. The newly arrived cattle are not adapted to the new feed. The first week should be based on hay, with silage properly, with little or no concentrate. During the early period of fattening, two times a day feeding, drinking water 3 times; late feeding 3 to 4 times a day, drinking 4 times. Brush cow body once daily in the afternoon and afternoon. Feces are often observed, such as dull stools, indicating less concentrate material; if it is thin or there are particles, it means that the feeding of the fine material is too much or bovine indigestion.
