Beef cattle feed for reducing carbon and nitrogen excretion and its preparation method and application

Abstract

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. The feed of the present invention comprises the following components and parts by weight: 0.1-1.5 parts of plant essential oil, 5-10 parts of peanut seedlings, 15-20 parts of silage corn with ears, 20-30 parts of distiller's grains, 12-16 parts of sorghum, and flaked corn 14‑18 parts, 4‑6 parts of soybean meal, 5‑8 parts of cottonseed meal, 5‑8 parts of corn germ meal, 3‑8 parts of soybean hull powder, 18‑22 parts of kelp powder, 0.2‑0.4 part of table salt, calcium hydrogen phosphate 0.5‑0.8 part, 0.6‑1 part of baking soda, 0.45‑0.6 part of stone powder, 0.03‑0.06 part of compound trace elements, 0.01‑0.02 part of multivitamin, 0.04‑0.06 part of functional additive, 0.04‑0.06 part of magnesium sulfate; The plant essential oil is composed of cinnamon oil, oregano oil and garlic oil in a mass ratio of 1‑30:5‑20:10‑25. The feed of the invention can not only satisfy the rapid growth of beef cattle, but also improve the utilization efficiency of feed, reduce carbon and nitrogen excretion, reduce environmental pollution, and improve the quality of beef cattle carcasses.

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

[0003] In recent years, there has been a lot of research work on the regulation of plant essential oils on rumen fermentation and animal production performance, but most of the research is currently focused on in vitro experiments. In addition, the positive effects of plant essential oils on rumen fermentation require the selection of specific compounds Optimum doses of ingredients and their active ingredients as well as feed composition and ratio, etc.
