Lean cattle grazing and fattening

Grazing fattening cattle is a fattening method based on the use of natural pastures. The grazing and fattening method has the advantages of low feeding cost, good fattening effect and easy to be popularized in the vast agricultural and pastoral areas. During the 150-day grazing and fattening period of lean cattle, the daily gain of local cattle was 0.5ml 0.7 kg, the daily gain of beef hybrid cattle was 0.8ml 1.2 kg, and the total weight gain of each cow was 100ml 180kg, which increased the economic benefit by 300Mel 400 yuan. The techniques of grazing and fattening cattle are introduced as follows.

1. The choice of fattening cattle is 6 years old, tall, healthy and disease-free meat hybrid bulls such as Charolais, Limousin and Simmental are grazed and fattened. Eliminated bulls, infertile cows, low-yield cows and incapacitated farm cattle can all increase meat production by grazing and fattening before slaughtering. The young and middle-aged cattle have strong grass-picking ability and good fattening effect; the fattening effect of old and frail cattle is poor, but it can also get a better weight gain effect after proper conditioning; the cattle that are too old, toothless, with serious digestive system diseases and infectious diseases have no fattening value.

two。 Deworming and stomach-strengthening cattle should carry out deworming and stomach-strengthening before grazing and fattening. As cattle often contact the ground with forage grass, various nematodes are often infected in the digestive tract, and parasites are also easy to be found in vitro, which can reduce daily gain by more than 35%. Therefore, before grazing and fattening, it is necessary to dispel internal and external parasites, and at the same time to strengthen the stomach in order to improve the effect of weight gain. The insect nematode developed and produced by China Agricultural University can simultaneously remove dozens of nematodes, such as lice, mites, ticks, @ # @ 261 parasites and other parasites in livestock and poultry, and has a significant fat gain effect. At a dose of 1 bag of powder or 2 capsules (containing 10 mg of active ingredient) for every 35 kg body weight, it can be taken or mixed with feed. Deworming is best arranged in the afternoon or at night, so that the worm can be excreted during the next day, so as to facilitate collection and treatment. It is best to stop eating for several hours before administration and only give drinking water to improve the efficacy. Deworming and strengthening the stomach can be carried out at the same time. For dyspeptic cattle with diarrhea, you can take Jianwei Powder once a day, 250 grams each time, for 2 days. Individual thin cattle were fed with Jianwei Powder and then fed with 250 grams of yeast powder once a day, or 100 tablets of yeast tablets were given.

3. The fattening period of grazing begins in late May and ends in late October. The method of grazing in small groups should be adopted, and about 10 heads per group should be used. Summer grazing should avoid the hot weather as far as possible, and adopt the grazing method of getting out early in the morning, returning late in the afternoon, and having more rest at noon. Graze for about 8 hours a day and drive the cattle into the shed or tie the trees for a rest at noon. Drink water once after each harvest and drink enough. Drink clean water, do not drink water from dead bubbles; do not graze in low-lying areas to prevent infection with fascioliasis. Autumn grazing should take good care of cattle, do not let cattle harm crops and vegetable fields, and prevent diarrhea and death caused by accidental consumption of vegetables and crop fruits. There should be no cows in the fattening herd, so as not to affect the feeding and fattening of the bulls. If there are more cows, you can group them separately. Fattening cattle should not be put into service to prevent "slipping".

4. To do a good job of supplementary feeding, the fattening method of grazing and supplementary feeding can be adopted, and the effect of weight gain is better. Supplementary feeding can be carried out half an hour after grazing at night. Each cow was supplemented with 5 kg of grass, 1 kg of corn, 0.3 kg of cottonseed cake, 50 grams of salt, 50 grams of urea and 20 grams of auxin. When supplementary feeding, feed the grass first, then mix the concentrate feed and various additives evenly, and then mix it in the grass until full. Under the condition of grazing and supplementary feeding, the daily gain of improved beef cattle was 1.5kg, and that of local yellow cattle was 1.25kg.

5. Most of the beef hybrid cattle were born in March-May, and their body weight could reach 250 kg in May of the following year. From the beginning of grazing and fattening in late May to the end of the fattening period in late October, the fattening cattle can be fattened when their body weight reaches 350 Mel 400 kg. If you don't go out of the hurdle in this way, you can enter the fattening period of house feeding in late October. After 3 months of intensive fattening, the fattening weight reaches 500 Mel 550kg. It is also very appropriate to play the hurdle during New Year's Day or the Spring Festival, and the price is also high.
