Embodiment Construction

[0023] We designed the formulation and pelleting process according to the nutrient level described in the summary of the invention, produced a small amount of product, and carried out a feeding test.

[0024] From March to June 2005, at the Kangle Dairy Farm in Hulan County, Heilongjiang Province, 20 healthy black-and-white milk cow calves with similar birth age and roughly the same body weight were selected and randomly divided into 2 groups, 10 in each group. The control group was weaned at 90 days of breastfeeding according to the traditional method; the test group was weaned at 45 days of breastfeeding, and trained to eat full-price pellets from 7 days of age until 90 days of age.

[0025] Test results: 1. The average body weights of the control group and the test group at the age of 90 days were 96.2 kg and 95.5 kg, respectively, and the average daily gain was (630.1 ± 1.3) g and (628.9 ± 1.2) g, tested by t (p > 0.05) ,The difference was not significant. 2. The average ...

Abstract

The present invention belongs to the technical field of the production of husbandry, which is a novel feed for early weaned calves (born 35 to 45 days after weaning), and has the advantages of safe feeding, easy digestion, easy assimilation, growth promotion, rumen development and the efficiency of breeding promotion. The present invention is based on the nutritional needs for calves, and the rawmaterials is strictly selected according to the calves digestion physiological characteristics, and considering the nutritional depletion in the process of granulation, the feed formula is designed and selected through the microcomputer by formula software, and then the feed is produced by expanded pellet feed production unit with the smooth appearance, uniform and appropriate hardness, 4 to 6 mmin diameter. The present invention is characterized in safe feeding, easy digestion, easy assimilation, growth promotion, rumen development and the efficiency of breeding promotion, which is of greatsignificance for ruminant animal breeding industry.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry production. It is a new type of feed suitable for early weaning of dairy calves (35-45 days after birth). It has the characteristics of safe feeding, easy digestion, easy absorption, growth promotion, rumen development and improvement of breeding benefits. Background technique [0002] Dairy cows are animals with a high feed conversion rate. They can convert plant resources such as straw, leaves, and pastures that humans cannot directly use, and by-product resources of rural processing, into advanced products such as milk, meat, leather, and biochemical products that humans need. The development of the dairy industry is an effective way to enhance the national physique, realize high-yield, high-quality, high-efficiency agriculture, develop sustainable agriculture, improve the environment, and realize a well-off society as soon as possible. [0003] Dairy calves are the basis for the deve...
