Beef cattle feed capable of reducing carbon and nitrogen excretion, and preparation method and application thereof

Abstract

The invention belongs to the technical field of animal feeds, and specifically relates to a beef cattle feed capable of reducing carbon and nitrogen excretion, and a preparation method and applicationthereof. The beef cattle feed capable of reducing carbon and nitrogen excretion comprises the following ingredients in parts by weight: 0.1-1.5 parts of plant essence oil, 5-10 parts of peanut seedling, 15-20 parts of silage corn with stigmata maydis, 20-30 parts baijiu distillers' grains, 12-16 parts of Chinese sorghum, 14-18 parts of compressed corn tablets, 4-6 parts of soybean meal, 5-8 partsof cottonseed meal, 5-8 parts of corn germ meal, 3-8 parts of bean hull powder, 18-22 parts of kelp powder, 0.2-0.4 part of edible salt, 0.5-0.8 part of calcium hydrogen phosphate, 0.6-1 part of sodium bicarbonate, 0.45-0.6 part of stone powder, 0.03-0.06 part of compound trace elements, 0.01-0.02 part of compound vitamins, 0.04-0.06 part of a functional additive, and 0.04-0.06 part of magnesiumsulphate; and the plant essence oil is composed of cinnamon oil, oregano oil and garlic oil at mass ratio of (1-30) to (5-20) to (10-25). The beef cattle feed disclosed by the invention is capable ofsatisfying rapid growth requirements of beef cattle, as well as improving feed utilization rate, decreasing carbon and nitrogen excretion, reducing environmental pollution and improving carcass quality of the beef cattle.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a beef cattle feed for reducing carbon and nitrogen excretion, a preparation method and application thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's demand for beef rich in amino acids and rich in taste is increasing, so the amount of beef cattle breeding is also increasing. Beef cattle are ruminants. The rations they eat need to be fermented in the rumen. After the nutrients are transformed, they are digested and absorbed by the body, and then the livestock products that people need are synthesized. Rumen fermentation is a complex process. After carbohydrates and nitrogenous substances are degraded in the rumen, bacterial proteins and volatile fatty acids are synthesized, which are utilized after entering the small intestine. The rumen degradation rate and outflow rate of differ...

AI Technical Summary

Problems solved by technology

The rumen degradation speed and outflow speed of different nutrients are different, so it will cause waste of carbon and nitrogen nutrients, and lead to problems such as insignificant daily weight gain of beef cattle, large ratio of feed to weight gain, long fattening cycle, low comprehensive benefits, and environmental pollution. Cause certain pollution, thereby restricting the development of the beef cattle industry
