Technical points for winter silage feeding

Silage refers to a green and succulent feed preserved in a closed silage facility (窖, 壕, tower, bag) that is fermented by lactic acid bacteria. Most of our county is made from corn. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

Feeding method uhF China Feed Industry Information Network - based on feed, serving animal husbandry

When feeding, you should feed less at the beginning and gradually increase to a sufficient amount to allow the livestock to have an adaptation process. Baking soda should be added to the cattle in time. When the silage is fed, the pH value in the rumen of the cattle is reduced, which is easy to cause acidosis. 1.5% baking soda can be added to the concentrate to promote gastric peristalsis, neutralize acidic substances in the stomach, increase feed intake, and increase digestibility. Conditional farmers can fully concentrate the concentrate, silage and hay to make a full-mix diet for feeding livestock, and the effect will be better. Frozen silage can not be fed, which will not only reduce the production performance, but also cause abortion of pregnant animals. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

It is advisable to take 1 time each afternoon and afternoon. The thickness of each silage should be no less than 10 cm, ensuring that the silage is fresh, the palatability is good, and the nutrient loss is minimized to achieve the best effect of feeding silage. The silage taken out should not be exposed to sunlight, and should not be piled up or scattered. It is best to use it in a bag and place it in a cool place in the barn. After each reclaiming, the silage in the crucible should be re-tread and then covered with a plastic sheet. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

Precautions uhF China Feed Industry Information Network - based on feed, service animal husbandry

1. Check if the silage is mildewed. The quality silage is greenish-green or yellow-green. The taste is sweet and sour. It has a strong wine scent or a sour pear flavor. It is soft and moist in the hands. If the feed turns black or brown, the smell is sour and smelly, and it is sticky or dry in the hand, which means that the silage has been mildewed, and the mildew inferior silage cannot be fed. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

2. If diarrhea is found during the feeding process, immediately reduce or stop feeding, check whether the silage is mixed with mildew or cause diarrhea due to other diseases, and continue feeding after the livestock returns to normal. Clean the feeding trough every day, especially the dead corners, clean up the deteriorated silage, and add fresh silage. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

3. After feeding silage, the amount of concentrate feed should be reduced as appropriate, depending on the livestock's grievances and other production performance, but it should not be reduced too much or too fast. Silos should be strictly protected against rodents and avoid passing some diseases to livestock. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

4. Scientifically determine the amount of feed. The amount of silage to be placed should be determined based on the weight and use of the livestock. Adult cattle are fed silage per 100 kg body weight: 5 kg to 7 kg for lactating cows, 4 kg to 5 kg for fattening cattle, 4 kg to 4.5 kg for cattle, 1.5 kg to 2.0 kg for bulls, and 1 kg per day for sheep Quantity: 4 kg to 5 kg for adult sheep, 0.4 kg to 0.6 kg for lambs; daily feeding amount per 100 kg of milk goats: 1.5 kg to 3.0 kg for lactating ewes, 1.0 kg to 1.5 kg for young ewes, 1.0 kg for rams ~ 1.5 kg; horse's daily feeding capacity: Serving horses can feed 12 kg to 15 kg per day, and breeding mares and cubs over 1 year old can feed 6 kg to 10 kg per day. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

In addition, the following points should be noted when feeding silage: uhF China Feed Industry Information Network - based on feed, serving animal husbandry

1. Silage generally accounts for less than 50% of the dry matter of the diet. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

2. According to the amount of feed, how much is used every day, otherwise it will be rancid or mildew. uhF China Feed Industry Information Network - based on feed, serving animal husbandry

3. The temperature in winter is low. When silage is fed in the morning, after the silage is taken out, it should be fed back after the temperature is properly raised. uhF China Feed Industry Information Network - based on feed, serving animal husbandry
