摘要
用特定的酸性溶液冲洗阴道和/或处理待用的精液,采用人工授精或本交方法配种,能控制出生的雄性仔兔数,降低性比率。试验结果表明,阴道处理组的出生仔兔性比为88.46(雄23只/雌26只),精液处理组为46.67(7/15),阴道精液联合处理组为56.10(23/41),对照组高达114.52(71/62)。各处理组的出生仔兔性比均低于自然性比的理论值(100);经X^2检验,阴道—精液联合处理组出生性比与自然性比间有显著差异(X^2=5.06,P<0.05)。该处理方法简单,易于掌握,效果较为可靠,且成本低,实用性强,适于推广应用。
To alter the sex ratio of offspring of rabbit,a specific acid solution was used to irrigate the vagina or to treat the semen before artificial insemination. The sex ratios of offspring born we 88. 46(male 23/female 26)in the vagina treatment group, 46. 67(7/15) in the semen treatment group and 56. 10(23/41)in the vagina-semen combination treatment group while 114. 52(71/62) in the control group. The results indicated the sex ratios in all treatment groups were lower than thenatural theory value(100). Through X^2—test, there was significant difference between the combination treatment group and the theory value(X^2=5. 06,P-<0. 05). The vagina semen treatment/ with this specific acid solution is simple,cheap,reliable and suitable for popularization.
