Problems solved by technology

Sudden weaning of lambs during early stall supplementary feeding will cause stress and reduce immunity of lambs
In the actual production process, there is no suitable time for stall separation, which creates difficulties for farmers in the management of lambs at weaning period

Embodiment 1

[0023] like figure 1 As shown, this embodiment provides a fence method for lambs when they are isolated from their mothers during early weaning, which specifically includes: the lambs enter the fence period 15 days after birth, and end 40 days after the lambs are born, and the lambs are born 40 days after the birth of the lambs. After 41 days of weaning, the daily separation time between lambs and dams was gradually extended during the stall period, and the lambs were supplemented during the stall period. Specifically:

[0024] 1) The lambs were marked with ear tags within 2d after birth, the stalls started at 15d, ended at 40d, and weaned at 41d.

[0025] 2) The daily stall time of 15-19-day-old lambs is 5.5-6.5 hours ( figure 1 Shown is 6h), AM: 7:30-10:30, PM: 15:30-18:30.

[0026] 3) 20-24-day-old lambs are supplemented with 7.5-8.5h ( figure 1 Shown is 8h), AM: 7:30-11:30, PM: 15:00-19:00.

[0027] 4) 25-29-day-old lambs are supplemented with 9.5-10.5h ( figure 1 Sh...

[0034] 1 Materials and methods

[0035] 1.1 Experimental animals

[0036] Selected 180 Duhu hybrid F1 lambs with similar body condition (with a birth date within 3 days, (a farm in Hebei Province (40°37'N, 115°8'E, 680m above sea level))), and divided into Three groups, 60 in each group, 30 males and females (10 single lambs, 10 double lambs, and 3 lambs each), were marked with the inner ear 2d after birth, started at 15d, and ended at 40d. During the period, they were given free access to water and licked salt bricks (immunization procedures were carried out according to the arrangement of the sheep farm).

[0037] 1.2 Experimental Design

[0038] Supplementary feeding schedule in the stalls: Group I lambs are supplemented in stalls for 6 hours every day (am: 7:30-10:30, afternoon: 15:30-18:30); group II lambs are supplemented in stalls for 15-19 hours. The day-old lambs were the same as group I (that is, the lambs were supplemented daily for 6 hours in the stall (am: 7:30...

Abstract

The invention discloses a weaning stall method for lambs, which belongs to the field of animal husbandry lamb feeding management. The method provided by the invention comprises that the lambs start to enter the stall period 15 days after birth, end at 40 days after the lambs are born, wean the lambs at 41 days after the lambs are born, and gradually extend the daily stall period between the lamb and the mother during the stall period time, and the lambs were supplemented during this stall time. The method can significantly improve the relevant economic indicators of the lambs, can overcome the disadvantages of the lambs' stress response and immunity reduction caused by the partition, and can significantly increase the economic benefits of breeding.

Description

technical field [0001] The invention belongs to the field of lamb feeding and management in animal husbandry, in particular to a weaning fence method for lambs, in particular to a fence supplementary feeding method when lambs are isolated from their mothers during early weaning, so as to achieve the purpose of increasing the growth rate of lambs, thereby reducing breeding costs. Background technique [0002] Appropriate early weaning can promote the growth of lambs, which is conducive to the recovery of body condition of ewes, shortens the reproductive cycle, and increases the number of lambs. Supplementary feeding of lambs in the early stage is a technology for training lambs to start eating at an early stage. It can promote the development of lambs fore-gastric and the improvement of digestive function, increase growth rate, reduce individual differences, and facilitate early weaning of lambs, large-scale fattening and prolong the lactation of ewes. Peak period. Compartm...
