A special milk replacer for weaning goats and lambs and its application

Abstract

The invention relates to a special milk replacing material for goat lambs and application of the special milk replacing material. The milk replacing material comprises the following components: corn powder, extruded soybean, flour, fatty powder, sugarcane, glucose, plasma protein powder, rice protein powder, whey powder, salt, mountain flour, calcium hydrophosphate, 1% of a composite premixed material, a complex enzyme, an antioxidant, yeast, choline, lysine, methionine and threonine, wherein the components are mixed and subsequently prepared into extruded particles, and then the extruded particles are sprayed by soybean oil and lard oil which is liquefied by heating during a tempering process. A raising experiment shows that the milk replacing material product for the goat lamb provided by the invention has the characteristics and performances of extrusion, puffing, high fat, high energy, balanced amino acid and easy digestion, absorption and granulation, and the product has various nutrition ingredients which are similar with that of goat breast milk, so the product provides a powerful support for realizing early ablactation of the goat lambs and further improving the reproductive performance of goats.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a special milk replacer for Yunnan goats and lambs at the weaning period and an application thereof. Background technique [0002] Yunnan is a large sheep-raising province in my country, and goats are the mainstay. According to the data of "China Animal Husbandry Statistics" in 2012, goats accounted for 89.34% of the total number of sheep. For a long time, due to the lack of early weaning feed (milk replacer) and related technologies for early weaning of lambs, the weaning age of Yunnan goat lambs is relatively late, generally at the age of 3 to 4 months, the lambs grow slowly, and the body condition of ewes recovers Poor, estrus lags behind, generally only one child is produced a year, thus making the goat breeding productivity level in Yunnan (95% slaughter rate) lower than the national average level (99% slaughter rate), so the development of Yunnan goat lamb milk replacer It ...

AI Technical Summary

Problems solved by technology

However, goats and sheep are animals of the same family and different genus. Goats are more difficult to domesticate and house-raised, and they are more picky about food, and the milk fat and milk protein contained in sheep milk are higher than those of goat milk. Therefore, the milk substitute of sheep for meat The material cannot be directly applied to goat lamb

At the same time, the goat breeding in Yunnan is mainly based on farmers, who are very sensitive to the price of feed. The sheep milk replacer for meat is added with a large amount of whole milk powder, and the cost will inevitably be high. If the price of the milk replacer is high, it will be difficult It is difficult for farmers to accept the advanced feeding method of using milk replacer to wean lambs early, which directly restricts the productivity of Yunnan goats

[0004] In addition, the milk substitutes of other livestock species in China are often powdery materials, and young goat lambs like to kick, step, and pick up food. Feeding goat lambs with powdery materials will inevitably waste a lot of feed

Granulation can effectively solve this problem, and it is easy to store and transport, but if you want to granulate, the current ordinary granulator can only accept the addition of fat within 4%, while goat breast milk has a high fat content and is mostly short-chain unsaturated Fatty acid, in order to make the nutritional level of lamb milk replacer closer to goat breast milk, more than 16% fat must be added to the formula composition of goat lamb milk replacer, so it is necessary to increase the step of adding fat in the preparation process; finally, there is no Goat and lamb feeding standards, and in terms of the overall nutritional level, there is even a lack of formula nutritional indicators and practical applications of essential amino acids
