Problems solved by technology

[0004] The present invention provides a special concentrated feed for Tibetan sheep and its preparation method, aiming to solve the problem of malnutrition in winter and spring of Tibetan sheep due to the harsh natural environment of the plateau, the withered grass period of up to 7 months, the absence of absolute frost-free period in some places, and the degradation of grasslands. , the lambs have small birth weight, low survival rate, slow growth rate, long feeding cycle, low output benefit of Tibetan sheep, and harsh climate conditions seriously restrict the development of plateau sheep breeding industry.

Embodiment example 1

[0043] 100 late-pregnancy Tibetan ewes were randomly divided into two groups, and a 60-day feeding experiment was carried out. One group was supplemented with a mixture of 30% concentrated feed + 60% highland barley + 10% oats at 0.23kg / head after returning from pasture at night. One group was supplemented with a mixture of 50% highland barley + 50% oats at 0.23kg / head. The results showed that lambs produced by late-pregnancy Tibetan ewes were supplemented with a mixture of 30% concentrated feed + 60% highland barley + 10% oats. The birth weight was 10% higher than that of lambs produced by late-pregnancy Tibetan ewes supplemented with a mixture of 50% highland barley + 50% oats.

Embodiment example 2

[0045] 100 late-pregnancy Tibetan ewes were randomly divided into two groups, and a 60-day feeding experiment was carried out. One group was supplemented with a mixture of 30% concentrated feed + 60% highland barley + 10% oats at 0.23kg / head after returning from pasture at night. One group was supplemented with a mixture of 50% highland barley + 50% oats at 0.23kg / head. The results showed that the milk production of Tibetan sheep ewes in the late pregnancy was supplemented with a mixture of 30% concentrated feed + 60% highland barley + 10% oats. The milk yield of Tibetan ewes in the late pregnancy was 12.6% higher than that of late-pregnancy Tibetan ewes supplemented with a mixture of 50% highland barley + 50% oats.

Embodiment example 3

[0047] 100 late-pregnancy Tibetan ewes were randomly divided into two groups, and a 60-day feeding experiment was carried out. One group was supplemented with a mixture of 30% concentrated feed + 60% highland barley + 10% oats at 0.23kg / head after returning from pasture at night. One group was supplemented with a mixture of 50% highland barley + 50% oats at 0.23kg / head. The results showed that lambs produced by late-pregnancy Tibetan ewes were supplemented with a mixture of 30% concentrated feed + 60% highland barley + 10% oats. Compared with the survival rate of lambs produced by late-pregnancy Tibetan ewes supplemented with a mixture of 50% highland barley + 50% oats, the survival rate of lambs increased by 15.6%.

Abstract

The invention discloses a special concentrated feed for Tibetan sheep and a preparation method thereof. The special concentrated feed comprises the following components by weight percent: 22.16% of sunflower meal, 17.74% of rapeseed dregs, 15.69% of bean pulp, 11.95% of malt sprout, 20.99% of corn vinasse, 9.04% of microelement additive, and 2.43% of salt. The preparation method comprises steps of when the special concentrated feed is prepared, firstly mixing the sunflower meal, the rapeseed dregs, the bean pulp, the malt sprout, and the corn vinasse according to certain mass ratio, smashing and blending; then adding the microelement additive and the salt into the smashed raw materials and fully mixing and blending; and finally packaging the special concentrated feed for Tibetan sheep. The special concentrated feed can guarantee that the Tibetan sheep can spend winter and spring safely and can ensure the nutrition supply for the Tibetan sheep in gestation period, thus improving the survival rate and birth weight of the lamb and the survival rate of the lamb weaning in the year of birth, and having obvious comprehensive economic efficiency.

Description

technical field [0001] The invention belongs to the technical field of concentrated feed preparation, and in particular relates to a special concentrated feed for Tibetan sheep and a preparation method thereof. Background technique [0002] Tibetan sheep is one of the three original sheep breeds in my country, mainly distributed in the Qinghai-Tibet Plateau, and Qinghai is the main production area. According to its ecological environment, combined with production and economic characteristics, it can be divided into three types: plateau type, valley type and Euler type. The plateau type accounts for 90% of the province and is the main body of Tibetan sheep, mainly distributed on the Qinghai-Tibet Plateau at an altitude of 2880-3500m. Tibetan sheep has the characteristics of cold resistance, roughage resistance, stable genetics, and good meat production performance. It is the main livestock species on the Qinghai-Tibet Plateau. [0003] Due to the harsh natural environment o...
