摘要

Abstract

[Objectives]The effectiveness of conservating and breeding Weining sheep was systematically and quantitatively evaluated to provide a scientific basis for the directed breeding of Weining sheep with both meat and wool production.[Methods]A breeding experiment was conducted at a Weining Sheep Conservation Farm in Guizhou Province from 2022 to 2023.A semi-stall-side and semi-wooing feeding regime was used to systematically measure the reproduction performance,growth and development,slaughter performance,meat quality,and wool performance of the core conservation population of Weining sheep.The patterns of improve-ment in these key traits were analyzed.[Results]The rate of lambing for the first-time and multiparous ewes in early 2023 were 100.85%and 101.26%,with an increase of 0.85%and 1.26%compared to that in 2022.The body weight and average daily gain of weight in 3-month-old and 6-month-old lambs was 14.51 kg,24.36 kg,and 233.56 g,significantly higher than that in 2022(P<0.05).Among the 6-month-old breeding ewes,the greatest increase in body height was observed in males(17.36%)and females(18.15%),with the smallest in-crease of chest circumference.In terms of slaughter performance,the eye muscle area and cooked meat yield was significantly increased(P<0.05),while the indexes of remaining slaughter and meat quality had no signifi-cant difference between the two years(P>0.05),with tender meat and stable quality.The indexes of wool per-formance had a slight increase,with fiber fineness remaining stable between 32 and 46 deniers.[Conclusions]The major genetic traits of Weining sheep remained stable and had positive improvement after 2 years of sys-tematic conservation and breeding,with good effects of conservation.
