Lactating cows should have balanced nutrition, what are the feeding management methods of lactating

First of all, there should be a clean cowshed, the temperature should be kept at about 20 degrees not too low, should be fed on demand, when feeding lactating cows, should add more grass or feed with high protein content, but also give cows to drink some warm water, to be vaccinated regularly.

Be sure to feed the cows some high-quality feed, soybean meal, corn, vitamins, nutrient solution. Because these feeds all contribute to the healthy growth of cows, and they can also increase breast milk production.

They should be fed more nutritious feed, ventilated more, and given them plenty of water so that they can grow very well.

Be sure to choose high-quality nutrients, and at the same time pay attention to the ventilation effect, and pay attention to the matching of nutrients, pay attention to the grasp of the feeding time period.

The cattle should be treated every day, and they should also be disinfected with a disinfectant, so that they can be well managed and the cattle will be very healthy.

Nutrition standards are marked by the appropriate dietary standards for moderately developed cattle and finishing cattle according to the nutritional needs of the development and rearing stages (generally need to be fed concentrates. It is necessary to ensure the nutritional needs of cattle, but also not to make cattle overfat, too thin or waste feed, so as to gain daily weight in a good reputation. Diets with slightly higher energy and protein should be fed before 12 months of age, and the concentration of the diet should be gradually reduced thereafter.

After breeding and conception, it is necessary to increase the supply of protein and energy feed to prevent insufficient nutrition leading to too thin and pelvic dysplasia, causing dystocia, and at the same time to prevent over-fattening, 1 or 2 months before giving birth to appropriately improve the feed nutrition level of breeding cattle (generally need to increase concentrate).

1. Gilts generally refer to the 6-month-old calves to the first litter. In the calf stage, reasonable feeding is a necessary condition to ensure the healthy growth of the calf and reduce the economic cost. Breeding cattle are in the most vigorous period of growth and development, and we should pay attention to the reasonable ratio of feed in feeding, and breed in a timely manner, which is conducive to improving the productivity of cows and reducing the cost of production.

2. The moisture content in the growth feed of gilts should not exceed 50%, which includes limiting the content of silage and green feed in the feed. It is also better to add hay to the green pasture of the gilt.

3. When the gilt is normal after pregnancy, its feeding management should be changed. The nutrition of mated cows can be divided into two phases: from gestation to the first 60 days of expected calving and the last 60 days of gestation.

In the first stage, the feed should be designed to take into account growth and avoid fat deposition. Obviously, if fed a high-energy, low-protein diet, the breeding cow is prone to fat deposits under the abdomen, which will have an impact on future reproductive performance.

4. The consumption of high-moisture feeds (e.g. forage and silage) can be estimated by assuming that the feeding capacity of the gilts is air-dried for their body weight. To estimate the feed intake of a grain with 31% dry matter (average dry matter content of forage), 89 (average dry matter content of air-dried feed 89%) can be divided by 31 to obtain factor 2 87。

When fed only a 31% dry matter diet, the cow expects 3% times its body weight to eat 3% of its dry matter intake. Since the physical characteristics of the cattle (body size and body shape) are also a factor affecting feed intake, the above method can only be used as a rough estimate.

5. In the third trimester of pregnancy, the type of concentrate in the feed of the gilt should be similar to that of the lactation period. The transition from early gestation to milk-producing grain-containing mixtures should be gradual over several periods, and the increase in lactating diets should be based on manure stability and feed acceptance of gilts during the transition period.
