Compound feed for relieving lamb stress, and preparation method and application thereof

Abstract

The invention particularly provides a compound feed for relieving lamb stress. The compound feed is prepared by adopting multiple mineral elements and vitamins as raw materials, compounding bacillus natto, bacillus subtilis and lactic acid bacteria into compound probiotics, and combining the compound probiotics with yeast culture, probiotics, trehalose and skim milk powder. The compound feed has good effects on improving and solving transition stress, feed changing stress, weaning stress, immune stress, management stress and immune stress and preventing enterotoxaemia caused by clostridium welchii; the feeding transition time is short; after transition, the feed intake and the weight increase are not lower than 20% compared with those of a control group; furthermore, supplementary feeding of pasture is not needed; the compound feed can be used in cooperation with conventional feed; and the compound feed can significantly reduce the feeding cost, is safe and reliable, and has wide development value for lamb breeding.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and relates to a preparation method of lamb feed, in particular to the technical field of a compound feed for alleviating lamb stress, its preparation method and application. Background technique [0002] Sheep stress response refers to that when sheep are strongly stimulated, the concentration of adrenocorticotropic hormone in the blood increases rapidly through the hypothalamus, and a large amount of glucocorticoid is secreted. A series of neuroendocrine reactions, which lead to various functional and metabolic changes. The physiological response caused by stress is manifested as sympathetic nerve excitement, increased secretion of pituitary and adrenal cortex hormones, elevated blood sugar, increased blood pressure, increased heart rate, and accelerated breathing. The stress response may also lead to a certain degree of deficiency of trace elements such as sodium, potassium, chlorine,...

Problems solved by technology

However, if the stress response is too strong or too long, no matter whether these reactions are physiological or psychological, it will be harmful, causing discomfort to the body of the sheep in mild cases, and causing performance disorders in sheep in severe cases

[0004] For the goats in the pastoral areas of Xinjiang, there are many factors that cause stress when the grass-fat sheep go down the mountain: because the lambs have adapted to the mountain grazing environment, they have transition stress after going down the mountain; they used to graze on grasslands, but now they are transferred to pens In breeding, there is management stress due to drastic changes in stocking density; there is feeding stress when switching from grazing to feeding; there is weaning stress when the lambs switch from eating milk and grazing to eating feed after going down the mountain; Carry out the immunization programs of triple defense, small ruminant, sheep pox, foot-and-mouth disease, etc. The immune stress of lambs is relatively large, and the body condition of lambs generally does not increase but decreases at this stage; A large number of Clostridium multiplication, eventually causing enterotoxicity, diarrhea or lamb death

[0005] In the prior art, in the prior art, the invention patent with application number 201911290567.6 discloses "a nutritional feed set for early weaning of Tibetan lambs under grazing conditions and a method for early weaning of Tibetan lambs", and the invention patent with application number 201910504596.1 Provided "a fermented compound feed for lambs in the early stage of fattening", the invention patent with application number 201410504092.7 provided "a fully mixed ration feed that reduces the weaning stress of lambs", and the invention patent with application number 201911084924.3 provided "a Biological Feed and Its Preparation Method for Alleviating the Stress of Sheep Sheep Entering the Barn”, the invention patent with application number 201911140374.2 provides “anti-stress feed for ruminants prepared by fermented jujube powder”, the invention patent with application number 201911368889.8 “for Compound premixed feed for cattle and sheep", the invention patent with application number 201510977696.8 provides "a method and feed for the feeding of Hu sheep", all of which solve the stress caused by a single factor, such as weaning stress, during transportation, etc. Stress, etc., and needs to be configured separately when used, and the scope of application is small
