Problems solved by technology

[0006] The traditional lamb feeding management method does not carry out pregnancy tracking on pregnant ewes, and the ewes are allowed to give birth in centralized breeding pens. After the ewes give birth, some newborns will be caused by other ewes being trampled, squeezed or frightened by other ewes. The frequent occurrence of lamb deaths makes it the first "ghost gate" that lambs must go through under the traditional feeding management mode
Secondly, due to climate reasons such as high temperature and high humidity in summer and low cold and humidity in winter in southern China, as well as health and environmental problems in farms, ewes have a high incidence of mastitis, rough feeding of ewes makes them insufficient in nutritional intake, and insufficient milk secretion in lactating ewes. It has caused the phenomenon of high double lamb rate or triple lamb rate but extremely low survival rate in the southern goat industry, making the current average survival rate of lambs in the southern goat breeding industry less than 30%, and problems such as diarrhea, diarrhea, and keratoconjunctivitis However, the growth performance of lambs is greatly affected by ewe milk, and the growth performance such as average daily gain and weaning weight is low, which greatly limits the healthy development of the goat industry

Embodiment 1

[0043] The pregnant ewes were transferred to the farrowing house one week before delivery, and nutritional supplementary feeding was strengthened. Combined with the date of delivery, monitor the feeding behavior and movement behavior of ewes, prepare dry towels and disinfectant for delivery in advance, and provide individual care for lambs in time when delivery, remove mouth and nose dirt and wipe body surface, and The umbilical cord is disinfected, and then the newborn lamb is put back to the ewe. In winter, the lamb is kept warm and kept warm with a heat lamp, and the newborn lamb is assisted to suck breast milk as soon as possible; The umbilical cord of the lamb is sterilized, and attention is paid to keeping warm and assisting the lamb to suck breast milk.

[0044] Lambs eat enough colostrum at birth. If ewes have no colostrum, bovine colostrum can be used instead. After 3-5 days of age, try to feed the lamb with milk replacer. The milk replacer is diluted in warm boiling...

Embodiment 2

[0049] The pregnant ewes were transferred to the farrowing house one week before delivery, and nutritional supplementary feeding was strengthened. Combined with the date of delivery, monitor the feeding behavior and movement behavior of ewes, prepare dry towels and disinfectant for delivery in advance, and provide individual care for lambs in time when delivery, remove mouth and nose dirt and wipe body surface, and The umbilical cord is disinfected, and then the newborn lamb is put back to the ewe. In winter, the lamb is kept warm and kept warm with a heat lamp, and the newborn lamb is assisted to suck breast milk as soon as possible; The umbilical cord of the lamb is sterilized, and attention is paid to keeping warm and assisting the lamb to suck breast milk.

[0050] Lambs eat enough colostrum at birth. If ewes have no colostrum, bovine colostrum can be used instead. After 3-5 days of age, try to feed the lamb with milk replacer. The milk replacer is diluted in warm boiling...

Embodiment 3

[0055] The feeding and management method of Embodiment 2 is adopted in Embodiment 3, and the individual care from the birth of lambs, supplementary feeding of milk replacer, breeding environment control, and weaning management methods are all consistent with Embodiment 2, but in Embodiment 3, lambs At the age of 42 days, add 10g / d astragalus superfine powder to the milk replacer every day, and continue to feed the lambs until 60 days old, then replace the milk replacer with warm water to configure astragalus root superfine powder, and continue to feed the lambs at the weaning period From the age of 72 days, until the lamb successfully passed the weaning period, the superfine powder of astragalus root can be used to improve the immunity of the lamb and prevent diseases. The average particle size of the superfine powder is 2-50 μm, and the average specific surface area is 1.5 m 2 / g. A total of 18 newborn lambs were raised according to the feeding and management technology of E...

Abstract

The invention relates to a feeding method for improving the survival rate of southern lambs, said method comprising nursing of newborn lambs, artificial feeding of milk replacer, early induced feeding and feeding management scheme, breeding environment control and regular disinfection, transitional isolation of mother and child and Mild weaning, Chinese herbal medicine to enhance immunity and prevent diseases. The present invention makes the survival rate of the southern lamb reach more than 95% and increases the immunity of the lamb through six measures, such as birth care of the lamb, supplementary feeding of milk replacer, induction of early feeding, environmental control, benign weaning and supplementary feeding of Chinese herbal medicine. and production potential, improving the economic benefits of southern goat breeding.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and specifically relates to a feeding method for improving the survival rate of southern lambs. Background technique [0002] In response to national strategic needs, my country's animal husbandry industry is in urgent need of transformation and upgrading. Among them, the proportion of mutton sheep industry structure is increasing year by year, and the scale and standardization of sheep raising are gradually increasing. However, at present, my country's sheep raising industry is still in the primary stage of intensive farming, and is facing severe problems such as low degree of specialization, extremely low degree of informatization, backward breeding technology, and high breeding costs. Among them, the key to restricting the healthy and rapid development of the sheep raising industry The key point is that the survival rate of lambs is low. Due to the harsh climate environment of southern ...
