Problems solved by technology

[0003] In particular, due to the high altitude of the Qinghai-Tibet Plateau, harsh climate, and long cold season, the nutritional level of pastures has been low for nearly 7-8 months, which seriously affects the healthy development of pregnant ewes and fetuses. The birth rate of lambs is low, and the weaning surv

Embodiment 1

[0025] Components and content (in parts by weight) of supplementary feed for Tibetan sheep and ewes during pregnancy:

[0026] 55 parts of corn, 26 parts of highland barley, 15 parts of rapeseed cake, 2 parts of salt, and 2 parts of compound premix; said rapeseed cake and rapeseed cake contain 27% of crude protein. The above compound premix can be commercially available compound premix, but the guaranteed values ​​of vitamin and trace element content are: vitamin A≥800,000 IU / kg, vitamin D≥80,000 IU / kg, vitamin E≥1065IU / kg, Niacin ≥ 4000mg / kg; trace element selenium ≥ 20mg / kg, iodine ≥ 60mg / kg, manganese ≥ 4000mg / kg, iron ≥ 3300mg / kg, zinc ≥ 3200mg / kg, copper ≥ 1000mg / kg, cobalt ≥ 20mg / kg .

[0027] The timing of supplementary feeding starts when the ewes are pregnant for 3 months (i.e. mid-October) and ends when the lambs are weaned. The supplementary feeding is fixed and quantitative every day. kg.

Embodiment 2

[0029] A preparation method for supplementary feed for Tibetan sheep and ewes during pregnancy comprises the following steps:

[0030] 1) Crushing of raw materials 60 parts of corn, 22 parts of highland barley and 15 parts of rapeseed cake were crushed to 80 mesh. (2) The raw materials are mixed with 1 part of salt and 2 parts of compound premix for premixing, and the crushed corn, highland barley, rapeseed cake and premixed salt and compound premix of step (1) account for 15% of the total weight The water is mixed evenly in a mixer. (3) Granule forming The uniformly mixed raw materials enter the grass granule forming machine for extrusion molding, the broken parts are returned to the cage for further processing, and the formed granules enter the heat dissipation and cooling device. (4) Grain Cooling The water content of the cooled grass granules does not exceed 15%. After the granules enter the cooling device for heat dissipation and cooling, they are sent to the finished pr...

Embodiment 3

[0032] In mid-October, 2009, 20 Tibetan sheep ewes were selected for supplementary feeding, and the supplementary feeding was completed until mid-March, 2010. Every ewe was fed 0.5kg of this formula product at around 18:30 every day.

[0033] The comparison results show that the average weight of 20 ewes in the supplementary feeding demonstration households is 41.7kg, while the average weight of ewes without supplementary feeding is 31.57kg, and the weight of supplementary feeding ewes has increased by 32.09%; the average weight of lambs in the supplementary feeding demonstration households reaches 20.4kg kg, while the average weight of lambs from non-supplementary households was only 10.5kg; in addition, the survival rate of lambs from demonstration households with supplementary feeding was 98.35%, while the survival rate of lambs from households without supplementary feeding was 92%; the survival rate of lambs from ewes supplemented An increase of 6.35%.

Abstract

The invention is feed suitable for supplementary feeding of tibetan sheep ewe in pregnancy in alpine pastoral areas of tibetan plateau and a preparation method thereof, and is characterized in that corn, highland barley, table salt, a composite premix, and a rape cake are scientifically blended according to the nutritional requirement characteristics of tibetan sheep in pregnancy, and are processed into particle feed which is suitable for feeding and transportation and is used for correct supplementary feeding of tibetan sheep ewe in pregnancy. According to the invention, a supplementary feeding formula which is determined to be suitable for local agricultural and sideline product resource conditions and the nutritional requirement characteristics of tibetan sheep is adopted; by supplementary feeding of ewe in late pregnancy, the nutritional requirements of a fetus for rapid growth are met, and thus the survival rate of lambs is effectively increased. Meanwhile, an important local agricultural and sideline product of a rape cake is made full use of to reduce production cost, and particles are prepared which can overcome practical difficulties of far transportation distances and dispersed feeding sites, and are suitable for popularization and application in alpine pastoral areas of tibetan plateau.

Description

technical field [0001] The invention belongs to the technology of producing livestock feed with plant materials, more specifically, it is a kind of feedstuff with agricultural and sideline products in the alpine pastoral area of ​​the Qinghai-Tibet Plateau as the main raw material, and the formula is designed according to the nutritional requirements of Tibetan sheep and ewes during pregnancy, and processed into formula pellet feed Techniques for supplementary feeding. Background technique [0002] Tibetan sheep form a self-contained system in the alpine grassland animal husbandry production system on the Qinghai-Tibet Plateau, accounting for about 65%-70% of the animal breed structure, and are the main body of the animal husbandry economy. The harsh alpine living environment, coupled with the seasonal imbalance of natural pasture nutrition, causes the nutritional imbalance of Tibetan sheep under natural grazing conditions. state. Carcass nutrition goes through a vicious c...
