摘要
为研究滩羊生长发育和羊毛生长的关系,为滩羊饲喂提供可行性借鉴。试验选择2019年12月—2021年6月共6批滩羊数据,就不同年份周公、成公、周母、成母(含肩、侧、股等部位)的毛辫长、底绒长、细度、含绒率等相关数据进行调研分析。不同年龄的滩羊含绒率不同,2021-3-1周公含绒率47.04%、且成公含绒率最高,为63.42%;2021-6-1周母含绒率48.46%,成母含绒率46.16%;成公春毛含绒率最为63.42%,周目秋毛含绒率最高,为48.46%;成公滩羊侧部含绒率最高。滩羊生长发育和羊毛生长呈正相关,且遵循滩羊的生长发育规律,是提高羊毛质量的关键。基于不同年龄、不同性别、不同季节滩羊生长发育和羊毛生长的关系,通过增大羊的体格、合理饲料成本控制、提高单位面积的毛被密度,可为提高羊毛质量提供保障。
To study the relationship between growth and wool growth of Tan sheep,and to provide a feasible reference for tan sheep feeding.Methods:The data of six batches of Tan sheep from December 2019 to June 2021 were selected to investigate and analyze the data of brad length,underwool length,fineness and wool content of male,adult male,adult female and adult female(including shoulder,side and thigh)in different years.Results:The wool content of tan sheep of different ages was different,the male wool content of 2021-3-1 weeks was 47.04%,and the male wool content of 2021-3-1 weeks was the highest,63.42.For 2021-6-1 weeks,the maternal cashmere content rate was 48.46%and that of adult was 46.16%.The wool content of spring hair of adult male was 63.42,and that of autumn hair of Zhou mu was 48.46%.The cashmere content of the side part of Cheng Gong tan sheep is the highest.Conclusion:The growth and development of Tan sheep are positively correlated with wool growth,and it is the key to improve wool quality to follow the growth and development law of Tan sheep.Based on the relationship between the growth and wool growth of tan sheep in different ages,genders and seasons,the wool quality can be improved by increasing the size of sheep,controlling the feed cost reasonably and increasing the wool wool density per unit area.
