Total mixed fermented feed for mutton sheep fattening and preparation method thereof

Abstract

The invention discloses a total mixed fermented feed for mutton sheep fattening; the early-stage total mixed fermented feed comprises the following components by weight: 26-35 parts of mixed forage, 17-24 parts of straw, 7-13 parts of alfalfa, 15-24 parts of corn, 3-7 parts of cottonseed meal, 5-10 parts of sunflower cakes, 3-9 parts of flax cakes, 0.3-0.7 parts of calcium hydrophosphate, 0.5-1.0 parts of sodium bicarbonate, 0.5-1.1 parts of table salt, and 0.7-1.2 parts of composite premix of vitamins and trace elements; the later-stage total mixed fermented feed comprises the following components by weight: 25-35 parts of sunflower disc powder, 7-12 parts of straw, 7-13 parts of alfalfa, 25-35 parts of corn, 5-10 parts of dry vinasse, 2-5 parts of cottonseed meal, 5-9 parts of sunflower cakes, 0.3-0.7 parts of calcium hydrophosphate, 0.5-1.0 parts of sodium bicarbonate, 0.5-1.1 parts of salt, and 0.7-1.2 parts of composite premix of vitamins and trace elements. By lactic acid fermentation, the preparation method of the invention can increase the digestibility for dry matter of the feed, and facilitates long-term storage; the protein content and quality of the fermented feed are increased and improved; the utilization rate and conversion efficiency of the feed are increased; the feed intake and weight gain efficiency of mutton sheep are significantly increased; the mutton quality is improved.

Description

technical field [0001] The invention relates to a feed for ruminants and a preparation method thereof, in particular to a fully mixed fermented feed for fattening mutton sheep and a preparation method thereof. Background technique [0002] Fattening sheep refers to lambs with a weaning weight of about 15-20 kg for the purpose of producing mutton, and then go through intensive fattening for about 90 days before being slaughtered. The fattening period is divided into early and late stages, each period is about 45 days. [0003] The production of feed for fattening mutton sheep in my country has just started, and the household rate of compound feed is very low. At present, farmers mainly use their own agricultural and sideline products to feed mutton sheep after simple compounding. Therefore, the weight gain of fattening mutton sheep is slow due to unbalanced nutrition , the carcass weight at slaughter is low. The second is that farmers directly feed a large amount of poor-qual...

AI Technical Summary

Problems solved by technology

[0003] The production of feed for fattening mutton sheep in my country has just started, and the household rate of compound feed is very low. At present, farmers mainly use their own agricultural and sideline products to feed mutton sheep after simple compounding. Therefore, the weight gain of fattening mutton sheep is slow due to unbalanced nutrition , low carcass weight at market

The second is that farmers directly feed a large amount of poor-quality roughage such as straw without treatment, resulting in low digestibility and great pollution to the environment.

Third, long-term feeding of low-nutrition and unbalanced diets causes a higher incidence of pica and metabolic diseases in mutton sheep

Fourth, poor palatability affects the feed intake, fattening effect and mutton quality of mutton sheep
