[0047] Example 1 lamb milk substitute feeding test effect

[0048] From September to December 2009, a lamb milk replacer was formulated according to this patented technology, and a lamb feeding test was carried out in a sheep breeding farm in Mentougou District, Beijing. The newborn lamb calves were divided into 4 groups, 9 in each group, one group was suckling lambs from ewes; the other three groups were fed with three milk substitutes with crude protein levels of 21%, 25% and 29%, respectively. Lasts 90 days. The results showed that the daily gain of lambs fed with milk substitutes was lower than that of ewe-fed lambs at the age of 20-40 days, but it reached and gradually exceeded that of ewe-fed lambs after 40 days of age. At the same time, when the protein level of milk replacer was 25%, the lamb gained the best weight gain, and the average daily weight gain of the whole period reached 207.9g / d. See Table 1 for test data.

[0053] Example 2 Effects of milk substitutes with different crude protein levels on the digestion and metabolism of lamb nutrients

[0054] Newborn lamb calves were divided into 3 groups, 9 calves in each group, fed with three milk replacers with crude protein levels of 21%, 25% and 29%, respectively, and the experiment lasted for 90 days. Among them, when the lambs were 50-60 days old and 80-90 days old, 6 lambs were randomly selected from each group and placed in metabolic cages, and the digestion and metabolism test was carried out by using the method of total collection of feces and urine. Each period of digestion and metabolism lasted for 10 days, the first 5 days were the pre-feeding period, and the last 5 days were the trial period. The test results showed that during the period of 55-60 days of age, the deposition rates of nitrogen, calcium and total phosphorus in each group were not significantly different (P>0.05); during the period of 85-90 days of age, the nitrogen...

Abstract

The invention relates to a lamb milk replacer belonging to the field of the animal nutrition and forage science of the animal husbandry. In the invention, vegetable protein, such as soybean and the like, whey powder, milk sugar, water-soluble fat, an enzyme preparation, mineral substances, vitamins and the like, are taken as raw materials to prepare the lamb milk replacer according to a scientific formula, and the lamb milk replacer is used for replacing goat milk and milk to feed lambs which are 0-90 days old. The milk replacer contains various nutrient substances required by the growth and development of the lambs and reaches the optimal proportion. The lambs can use the lamb milk replacer after being born. The survival rate of the lambs under the condition of multiple lambs in a birth can be improved by using the milk replacer, and meanwhile, the digestion and the adsorption of the lambs to the nutrient substances can be promoted, thereby promoting the growth and development of the lamps. The application of the invention can bring visible economic and ecological benefits to the development of animal husbandry and mutton sheep breeding industry.

Description

[technical field] [0001] The invention relates to the production of a lamb milk substitute produced with active ingredients such as vegetable protein, dairy products, water-soluble fat and compound enzyme preparation, and belongs to the field of animal nutrition and feed science of animal husbandry. The invention also relates to the types and specifications of the raw materials required for the production of lamb milk substitutes, the nutritional components of the milk substitutes, feeding techniques and methods. [Background technique] [0002] From the late 1980s to the early 1990s, the world's sheep farming industry underwent tremendous changes. The total wool output dropped rapidly, while the lamb meat output increased year by year. The sheep industry turned to meat production, and the mutton sheep industry rose rapidly. Among them, the production of fat lamb and high-quality mutton will be the development trend of the current mutton sheep industry. The industrialized an...
