In the process of fattening beef cattle, beef cattle need to feed quickly, must be scientific feeding, take appropriate feeding management measures. Next, we will mainly talk about these three stages of feeding and fattening.
The first phase is from half a month to 20 days, mainly to regulate the gastrointestinal tract of cattle, increase appetite, mainly based on roughage. In the first 10 days, only the grass is fed, and the concentrate is not fed. It can be mixed with half of the short corn stalk and the green hay. For cattle with poor appetite, corn flour or wheat flour can be used. After fermentation, it is fed to about 250 grams per day, and try to feed grass and sweet potato vines. After 10 days, add about 2.5 kg of concentrate per day. The feed formula is: corn stalk 20%, high quality green hay 50%, corn flour 10%, bean cake 10%, bran 10%.
In the second stage, 40 to 45 days, gradually increase the proportion of concentrate. The feed formula is: high quality green hay 40%, corn stalk 20%, corn flour and bran 10% each, bean cake 20%, salt 50 grams per day. The grass is fully supplied, allowing the cattle to eat freely.
The third stage is the late fattening, which lasts for one month and is mainly based on concentrate. The feed formula is: corn stalk 10%, high quality green hay and bran 20%, corn flour 35%, bean cake 15%, salt 50 grams per day. At any stage, the forage must be shortened and shredded, and the concentrate must be crushed.
If necessary, the forage is preferably treated with lime water or ammoniation. Lime water treatment: soak the short straw with a 1% quicklime solution for 10 minutes, drain and drain, and feed the cattle after one day. Ammonia treatment: evenly sprayed on the straw with 10% aqueous urea solution, and then sealed in a plastic bag for 7 days. Feed each time, feed the grass first, then mix in the concentrate. Drink water should be fresh and clean.
If the source of local distiller's grains is sufficient, the fattening feed can be changed to: In the first month, each cow is fed 10~15 kilograms of distiller's grains per day, adding 50 grams of urea and 3 kilograms of grass. In the second month, 15~20 kilograms of distiller's grains were fed every day, plus 50 grams of urea, 2.5 kilograms of grass, and 1 kilogram of corn flour. In the last month, more than 20 kilograms of distiller's grains were fed, 50 grams of urea, 1.5 kilograms of grass and corn flour. It should be noted that the urea can not be interrupted, and each time it is directly sprinkled in the concentrate to mix well, it can not be fed alone, nor can it be dissolved in water to feed.
Finally, we must strengthen daily management, and keep the bullpen clean and dry. Adhere to the fixed slot, regular feeding. Feed once every morning at 5 am, 10 am, and 5 pm. It is necessary to minimize the activity of the cattle, and to achieve one cow and one pile, the length of the reins is no more than 50 cm. Brush the cow once a day to promote the blood circulation of the cow. Pay attention to heatstroke and cool down in summer to ensure the supply of drinking water. Pay attention to cold and warm in winter.
