Milk replacer for weaning killing calves

Abstract

The invention discloses a milk replacer for weaning killing calves. The invention provides the milk replacer for weaning calves of 30-60 days old and 60 days old or above respectively according to the characteristics of digestive physiology and nutrient substances of the killing calves. According to the milk replacer disclosed by the invention, non-milk-derived sugar source and protein source materials such as cured corn starch and soy protein which are cheap and readily available are used, and a compound enzyme preparation is also used, and thus the digestion and utilization rate of the calves to corn starch and soy protein is improved; by adding a flavoring agent, the preference level of the calves to the milk replacer is improved; by using probiotics, the balance condition of intestinal flora of the calves is improved; by adding an acidifier, the milk replacer is at a suitable lower pH value, and the digestion of the calves to protein is benefited; various nutrient substances are comprehensive property and are reasonably proportioned; a nutritional value of the milk replacer is superior to that of whole milk; quicker growth and development of the calves are realized.

Description

technical field [0001] The invention belongs to the field of calf feeding, and in particular relates to a milk substitute for weaning of meat calves. Background technique [0002] In traditional feeding techniques, meat calves are generally weaned at 4-5 months of age, and are raised with the cow throughout the whole period. In the middle and late stages of feeding, this feeding method gradually fails to meet the nutritional needs of fast-growing calves. In recent years, with the improvement of the level of beef cattle cultivation in my country, the number of large-scale beef cattle farms has continued to increase. The traditional breeding methods can no longer meet the needs of high-efficiency beef cattle production. Post-weaning performance. In addition, a too long weaning program will increase the cost of calf cultivation and reduce the efficiency of the farm. Taking the 90-day-old weaning program as an example, the calf needs to consume 350-500kg of milk in total. There...

[0002] In traditional feeding techniques, meat calves are generally weaned at 4-5 months of age, and are raised with the cow throughout the whole period. In the middle and late stages of feeding, this feeding method gradually fails to meet the nutritional needs of fast-growing calves

In recent years, with the improvement of the level of beef cattle cultivation in my country, the number of large-scale beef cattle farms has continued to increase. The traditional breeding methods can no longer meet the needs of high-efficiency beef cattle production. Post-weaning performance

In addition, a too long weaning program will increase the cost of calf cultivation and reduce the efficiency of the farm. Taking the 90-day-old weaning program as an example, the calf needs to consume 350-500kg of milk in total

There are also some cattle farms that blindly advance the weaning time of calves to 30 days in order to unilaterally improve production efficiency, but early weaning requires scientific methods and mature supporting technologies. Premature early weaning is still in a developing stage. This has a great negative effect on calves, which often cause severe calf stress, which usually lasts for a long time, and the calf's feed intake will be significantly reduced, eventually leading to calf Growth retardation, emaciated body condition, reduced production performance
