Mutton sheep breeding method capable of realizing five births and ten lambs in three years

Abstract

The invention discloses a mutton sheep breeding method capable of realizing five births and ten lambs in three years. The breeding method comprises the following steps: S1, selecting back ewes of Sahan sheep as a parent female parent and Suffolk sheep as a parent male parent; S2, making sure that the back ewes are medium-to-high fat before breeding; S3, performing first breeding according to a ratio of one purebred Suffolk sheep as the parent male parent to 15 back ewes or less than 15 back ewes when the back ewes as the parent female parent are in estrus for the first time; S4, performing second breeding according to a ratio of one purebred Suffolk sheep as the parent male parent to 30 back ewes or less than 30 back ewes when the back ewes as the parent female parent are in estrus for thesecond time; S5, one week after delivery, adding high-protein feed for the back ewes, and ensuring that the feed in a feed trough of the back ewes is surplus when feeding at night to facilitate foodsupplementing of the back ewes; and S6, after delivery, when lambs are two months old, the lambs are separated from their mothers and forced to wean, and the lambs are specially raised to ensure thatthe lambs can eat feed in a sheep trough.

Description

technical field [0001] The invention relates to the technical field of mutton sheep breeding, in particular to a method for raising mutton sheep with five litters and ten lambs in three years. Background technique [0002] Mutton has high protein content, low fat and cholesterol content, and contains many essential amino acids for the human body, with high nutritional value; mutton is warm in nature, can nourish the middle and Qi, appetize and strengthen, nourish gallbladder and improve eyesight, and regular consumption is beneficial to anti-cancer, therapeutic Chronic cough and asthma, improve immunity.
