Calf feed

Abstract

The invention relates to calf feed, in particular to calf feed suitable for calves in a lactation period or weaned calves. The calf feed comprises the following raw materials in parts by weight: 10 parts of calf premix, 100-400 parts of corn, 50-150 parts of corn germ meal, 50-100 parts of soybean meal, 30-100 parts of dried corn full-alcohol trough, 10-150 parts of wheat middling and 30-150 partsof bran. The calf premix is prepared from the following raw materials: vitamin A acetate, vitamin D3, dl-alpha-tocopheryl acetate, a copper glycinate chelate, zinc sulfate, manganese sulfate, calciumiodate, cobalt chloride, sodium selenite and selenium yeast. The calf feed disclosed by the invention can effectively improve the daily feed intake of calves to dry matters, improve the daily gain, promote the development of early-stage key tissues of the calves and reduce the diarrhea rate of the calves.

Description

technical field [0001] The invention relates to the field of dairy cow feed, in particular to a dairy cow feed suitable for lactating calves or weaned calves. Background technique [0002] In recent years, with the rapid development of the domestic dairy farming industry in the direction of scale and intensification, the production level of many pastures has been significantly improved. Cultivation of back-up cattle, especially the early cultivation of calves has gradually been recognized and valued by dairy farming peers. The calf stage is a key period for the growth and development of dairy cows. High-quality calf breeding will have a major impact on the future economic benefits of the ranch, which will help improve the future competitiveness of the ranch and ultimately maintain the sustainable development of the ranch. [0003] The calf rearing phase may seem like an investment with no return, but more and more studies show that the nutrition, management and growth rate ...

AI Technical Summary

Problems solved by technology

[0006] (1) In the existing calf feed formula, there are unreasonable ratios of coarse grain fiber, protein, amino acid, starch, and additives, which in turn lead to incomplete nutritional intake of lactating calves, poor body resistance, and prone to diarrhea. Unsatisfactory development of key tissues such as skeleton, muscle, rumen, mammary gland, and reproductive organs;

[0007] (2) The existing calf feed has poor palatability and low feed conversion rate, which cannot increase the daily feed intake of the calf and improve the daily gain of the calf;

[0008] (3) In the premix of existing calf feed, the vitamins and minerals contained in the premix are not fully added or added in an unreasonable proportion, which cannot meet the daily nutritional needs of lactating calves, which in turn affects the development and development of the calf's body tissue. the body's resistance;
