Embodiment 1

[0033] In Tianjin Huize Animal Husbandry Co., Ltd., 24 newborn female calves with a body weight of 36-50 kg were selected. According to the order of birth, the female calves were divided into a control group and an experimental group by using a completely randomized experimental design method, with 12 female calves in each group. head calf. The control group and the experimental group were fed colostrum + acidified milk + calf pellets in stages, and were weaned at the age of 60 days.

[0034] Control group: 1-2 days old fed colostrum 6kg / d above, when feeding colostrum, colostrum quality assessment was carried out with colostrum refractometer, colostrum was qualified to be fed, adopted 4+2 colostrum feeding mode; At the age of 3-57 days, they can eat acidified milk ad libitum, and at the age of 58-60 days, gradually reduce the feeding amount of acidified milk. At the age of 60 days, they are weaned and drink water freely. At the age of 3 days, they start to eat calf pellets ad...

[0050]In Tianjin Huize Animal Husbandry Co., Ltd., 24 newborn female calves with a body weight of 36-50 kg were selected. According to the order of birth, the female calves were divided into a control group and an experimental group by using a completely randomized experimental design method, with 12 female calves in each group. head calf. The control group and the experimental group adopted the feeding program of colostrum + acidified milk + calf pellets in stages, and both were weaned at 60 days of age.

[0051] Control group: 1-2 days old were fed more than 6kg / d of colostrum, when feeding colostrum, the colostrum quality was first evaluated with a colostrum refractometer, and a 4+2 colostrum feeding mode was adopted; 3-57 days old were free Feed acidified milk, gradually reduce the feeding amount of acidified milk at the age of 58-60 days, wean at the age of 60 days, drink water freely, and start to eat calf pellets freely at the age of 3 days.

Abstract

The invention discloses compound premixed feed added to acidified milk for sucking calves and application of the compound premixed feed. The compound premixed feed is prepared from vitamins, trace elements, mineral substances, coccidiostats, lactoferricin and saccharides. By adding the vitamins and the trace elements to the product disclosed by the invention, the occurrence of vitamin deficiency of calves is effectively prevented, the immunity of the calves is improved, the development of epithelial cells of the intestinal tracts is promoted, a good intestinal micro-flora is established, the morbidity of diarrhea is reduced, the affects of stress reactions of weaning, horn removing and the like of the calves are reduced, and thus the calves can develop into strong bred cattle. The compoundpremixed feed disclosed by the invention has an obvious feeding effect, is convenient in raw material source and reasonable in price, can reduce the morbidity of diarrhea of the calves and can increase the weaning weight, wherein the weaning weight of 60-day-old calves is averagely increased by 3kg, and the economic benefit can be increased by about 72 yuan / calf.

Description

technical field [0001] The invention belongs to the technical field of calf feed, and relates to a compound premixed feed product added to acidified milk of lactating calves, which is suitable for calves aged 3-60 days and can successfully wean the calves at the age of 60 days. Background technique [0002] At present, dairy farms generally use milk replacer or milk (fresh milk or whole milk powder) to feed calves. Especially in the case of low milk prices or difficult sales, more dairy farms have given up using milk replacer and fed milk to calves after pasteurization or acidification. For newborn calves, milk is a high-quality source of nutrition, with high milk fat and milk protein digestibility (99-100%) and good palatability. But milk still has certain limitations, especially whole milk powder or milk that has been pasteurized for long-term storage. [0003] The content of various trace elements in milk cannot meet the requirements of normal growth of calves, such as ...
