Matters needing attention in feeding Beef cattle with Distiller's grains

The nutritional value of distiller's grains varies with different kinds of raw materials. Distiller's grains is rich in protein, crude fat and B vitamins, energy, linoleic acid and many unknown growth factors, which is a cheap and high quality feed for beef cattle. In 852, the fattening base of high-quality beef cattle in Waoye has been using distiller's grains to raise fattening cattle for six years and has accumulated some experience.

Quality requirements of distiller's grains

The main raw materials of distiller's grains used in our region are corn, sorghum and rice. At present, the loose material in the process of distiller's grains processing in our region is that rice husk accounts for about 50% of the total material, and the utilization rate of rice husk in beef cattle is only about 8%. Sell more distiller's grains and then mix 30% of the raw rice husk into the distiller's grains, which greatly reduces the effective nutrients and quality of the distiller's grains. These raw rice husks are very irritating to the bovine stomach and are easy to cause bovine stomach disease, so the dosage should be limited to a certain amount.

Lees fed to cattle must be fresh, moldy clots should be picked up in time, stones, cinders and other sundries should be cleaned up. First of all, from the color, taste, good lees to see a lot of residual grain, taste, strong fragrance. On the other hand, the quality of blackened gray is poor. Sorghum distiller's grains contains a lot of bitter taste, high acidity and poor palatability of cattle.

Feeding method of Distiller's grains

Distiller's grains can be added to the diet of fattening cattle (more than 600 jin). After deworming and strengthening the stomach, the fattening shelf cattle begin to add 2 jin of distiller's grains to the forage grass every day, so that the cattle can adapt to eating lees, and the amount will be gradually increased to about 15 kilograms in about 10 days. It can be greatly increased in the middle stage of fattening, and the maximum daily feeding can be 30kg to 40kg. During the adaptation period, very few cattle are sensitive to distiller's grains, so they can be put aside according to their growth conditions, and the amount of distiller's grains can be limited to prevent poisoning. Feeding methods:

1. Mix fresh distiller's grains evenly into silage, microsilage or powdered forage. According to the amount of distiller's grains, 150 grams of soda is added to adjust the acidity of the lees. Prevent oral and gastrointestinal diseases. If the forage grass is mainly silage, the amount of soda will be increased by about 0.2%. To prevent acidosis in beef cattle due to the extensive use of distiller's grains silage.

2. When using distiller's grains in winter, the frozen pieces of lees should be taken into the warm house first, and it is strictly forbidden to feed frozen lees directly to cattle, which will cause serious rumen disease in beef cattle. Such as late forestomach, hematochezia and so on.

3. Storage of distiller's grains: in summer and autumn, after the lees are shipped back, they should be immediately packed in a cellar or sealed with a large plastic bag. The distiller's grains will go bad after three days in summer. This spoiled distiller's grains does great damage to beef cattle. It is firmly abandoned and cannot be used.

4. when beef cattle were fed with distiller's grains for a long time, the proportion of nitrogen and phosphorus was out of proportion, and vitamin A, D and trace elements were deficient. There will also be metabolic disorders that slow the growth rate of beef cattle. Therefore, trace elements and vitamins should be added in time, and the easiest way is to add special premix for beef cattle to the diet. Can use land reclamation Xingwang brand feed. The amount of premixed feed is 2 taels per cow per day. The concentrated feed is 1 kilo to 3 jin per cow. (increased according to different stages of fattening) these nutritious feeds are very convenient to use and can be evenly mixed into the concentrate daily in proportion.
