Embodiment 1

[0025] Select 30 Hu sheep lambs with normal growth and development, healthy and disease-free, and they are randomly divided into two groups according to the principles of basically the same age at birth, similar weight, and close parity, with 5 replicates in each group, and 5 replicates in each replicate. 3 only. The experiment adopts a single factor experimental design, and the addition amount of leucine is 0, 0.66g / day per bird.

[0026] Lambs drink colostrum within 4 hours after birth, and eat freely with ewes until the fifth day. Separated from the ewes from the 6th day, began to feed the milk replacer, ad libitum, the daily average intake of the milk replacer measured at the age of 9 days was 260ml per meal, 780ml per day; For food (granular) and forage, in order to promote the intake of granules, the milk replacer is gradually reduced by 30ml per day until 210ml of milk replacer is fed every day and then kept until weaning. The starter and forage are free to eat and dri...

Embodiment 2

[0047] An early weaning breeding method for Hu sheep lambs, the feeding ration adopted in the breeding method includes milk replacer, starter, forage and leucine;

[0048] Lambs eat breast milk after birth, separate the lambs from the ewes at the age of 5 days, and feed milk replacer, feed once a day in the morning, noon and evening, and eat freely;

[0049] The milk replacer feed intake of each lamb was measured at the age of 9 days, and the average feed intake of the milk replacer at the age of 9 days was determined to be 780ml / day / only. At the age of 10 days, 780ml of milk replacer was fed per day per bird, and then gradually decreased to 30ml per day, until 210ml of milk replacer was fed every day, and then kept until weaning.

[0050] At the age of 10 days, the starter pellets, forage (Lymus chinensis) and leucine were added, wherein the starter and forage were provided for the lambs to eat freely and freely drink water. The feeding method is gavage feeding; leucine and ...

Embodiment 3

[0053] An early weaning breeding method for Hu sheep lambs, the feeding ration adopted in the breeding method includes milk replacer, starter, forage and leucine;

[0054] Lambs eat breast milk after birth, wean off breast milk at the age of 6 days and switch to feeding milk replacer, feeding 3 times a day, free to eat;

[0055] The milk replacer feed intake of each lamb was measured at the age of 9 days, and the average feed intake of the milk replacer at the age of 9 days was determined to be 800ml / day / only. At the age of 10 days, 800ml of milk replacer was fed per day per bird, and then gradually decreased by 30ml / day, until 240ml of milk replacer was fed every day, and then maintained until weaning.

[0056] At the age of 10 days, the starter pellets, forage (Lymus chinensis) and leucine were added, wherein the starter and forage were provided for the lambs to eat freely, drink water freely, and the leucine feeding amount was 0.7g / day / only. The feeding method is gavage fe...

Abstract

The invention relates to an early weaning breeding method of Hu lambs. According to the breeding method, an adopted feeding diet includes soybean milk powder, starters, forage and leucine. After being born, the lambs are fed with breast milk, and at the age of 5 days, the lambs are separated from ewes and fed with the soybean milk powder three times a day and eat freely; at the age of 9 days, the consumption of the soybean milk powder of each lamb is measured, a basis is provided for limiting the consumption of the soybean milk powder, and the Hu lambs are fed with the soybean milk powder in a gradual decreasing mode; at the age of 10 days, starters, forage and leucine are provided, the lambs can freely eat starters and forage, and the intake of the soybean milk powder is reduced day by day so as to increase the solid feed intake of the lambs; at the sage of 30 days, the lambs are stopped to be fed with leucine, soybean milk powder and the starters. The breeding method achieves the early weaning of the Hu lambs, the weaning stress of the lambs is effectively alleviated, and the production performance and the slaughter performance are improved.

Description

technical field [0001] The invention belongs to the field of animal husbandry, in particular to an early weaning breeding method for Hu sheep. Background technique [0002] In recent years, great changes have taken place in the sheep raising industry in the world, from the use of wool to the direction of meat or both meat and wool, so the mutton sheep industry has developed rapidly. Large-scale fat lamb production has become the main business model of mutton sheep industry abroad, accounting for more than 90% in the United States, and more than 80% in countries such as the European Union. In foreign countries, the vast majority of consumer demand for mutton is mainly lamb, which requires a large number of lambs, which inevitably requires shortening the production cycle of lambs and implementing early weaning. Due to the high degree of modernization of animal husbandry in foreign countries, the supporting equipment and measures of animal husbandry are relatively perfect, so ...
