Abstract Introduction The aim of the study was to determine the effect of the vitamins, omega-3 polyunsaturated fatty acid and minerals in the supplement Toryum administered before and during oestrus synchronisation on some fertility parameters of ewes during the non-breeding season. Material and Methods The experimental animals were clinically healthy Pirlak ewes, 55–75 days postpartum, aged 2–4 years and weighing 40–50 kg. A sponge was inserted into the vagina for 10 d (G1, n = 30; G2, n = 30) or 14 d (G3, n = 30; G4, n = 30) for oestrus synchronisation, and on the day of removal, 400 IU equine chorionic gonadotropin was injected. Toryum soft capsules were administered individually (1 capsule/ewe p.o.) to G1 and G3 ewes seven days before the sponge was inserted and on the day it was removed. Oestrus detection was started 12 h after sponge removal. Pregnancy was diagnosed by transrectal ultrasonography on the 30th day after mating. Results The pregnancy rate was statistically different between G1 and G4 (P < 0.05). The onset of oestrus was statistically different (P < 0.001) between the 10-d groups (G1 and G2) and the 14-d groups (G3 and G4). The litter size and oestrus, conception, lambing, multiple birth, and survival rates were not significantly different between the groups (P > 0.05). Conclusion Toryum administered to Pirlak ewes during progesterone-based oestrus synchronisation protocols during the non-breeding season may increase pregnancy rates. The relationship between Toryum and fertility parameters in ewes would be better understood by comprehensive studies.

Pirlak 母羊在非繁殖季节发情与含孕酮海绵和马绒毛膜促性腺激素同步:Toryum 能提高生育参数吗?

摘要 介绍 本研究的目的是确定在发情同步前和发情同步期间施用的补充剂 Toryum 中的维生素、omega-3 多不饱和脂肪酸和矿物质对非繁殖季节母羊某些生育参数的影响。材料与方法 实验动物为临床健康的皮尔拉克母羊,产后55-75天,年龄2-4岁,体重40-50公斤。将海绵插入阴道 10 天(G1,n = 30;G2,n = 30)或 14 天(G3,n = 30;G4,n = 30)用于发情同步,并在取出当天,注射了 400 IU 马绒毛膜促性腺激素。在海绵插入前 7 天和取出当天,分别给 G1 和 G3 母羊服用 Toryum 软胶囊(1 粒胶囊/母羊口服)。海绵去除后12小时开始发情检测。交配后第30天经直肠超声诊断妊娠。结果 G1、G4妊娠率差异有统计学意义(P < 0.05)。10 天组(G1 和 G2)和 14 天组(G3 和 G4)的发情期差异有统计学意义(P < 0.001)。各组产仔数、发情、受孕、产羔、多胎、成活率无显着差异(P > 0.05)。结论 在非繁殖季节,在基于孕酮的发情同步方案中,对皮尔拉克母羊施用 Toryum 可能会提高妊娠率。通过综合研究可以更好地理解 Toryum 与母羊生育参数之间的关系。交配后第30天经直肠超声诊断妊娠。结果 G1、G4妊娠率差异有统计学意义(P < 0.05)。10 天组(G1 和 G2)和 14 天组(G3 和 G4)的发情期差异有统计学意义(P < 0.001)。各组产仔数、发情、受孕、产羔、多胎、成活率无显着差异(P > 0.05)。结论 在非繁殖季节,在基于孕酮的发情同步方案中,对皮尔拉克母羊施用 Toryum 可能会提高妊娠率。通过综合研究可以更好地理解 Toryum 与母羊生育参数之间的关系。交配后第30天经直肠超声诊断妊娠。结果 G1、G4妊娠率差异有统计学意义(P < 0.05)。10 天组(G1 和 G2)和 14 天组(G3 和 G4)的发情期差异有统计学意义(P < 0.001)。各组产仔数、发情、受孕、产羔、多胎、成活率无显着差异(P > 0.05)。结论 在非繁殖季节,在基于孕酮的发情同步方案中,对皮尔拉克母羊施用 Toryum 可能会提高妊娠率。通过综合研究可以更好地理解 Toryum 与母羊生育参数之间的关系。10 天组(G1 和 G2)和 14 天组(G3 和 G4)的发情期差异有统计学意义(P < 0.001)。各组产仔数、发情、受孕、产羔、多胎、成活率无显着差异(P > 0.05)。结论 在非繁殖季节,在基于孕酮的发情同步方案中,对皮尔拉克母羊施用 Toryum 可能会提高妊娠率。通过综合研究可以更好地理解 Toryum 与母羊生育参数之间的关系。10 天组(G1 和 G2)和 14 天组(G3 和 G4)的发情期差异有统计学意义(P < 0.001)。各组产仔数、发情、受孕、产羔、多胎、成活率无显着差异(P > 0.05)。结论 在非繁殖季节,在基于孕酮的发情同步方案中,对皮尔拉克母羊施用 Toryum 可能会提高妊娠率。通过综合研究可以更好地理解 Toryum 与母羊生育参数之间的关系。结论 在非繁殖季节,在基于孕酮的发情同步方案中,对皮尔拉克母羊施用 Toryum 可能会提高妊娠率。通过综合研究可以更好地理解 Toryum 与母羊生育参数之间的关系。结论 在非繁殖季节,在基于孕酮的发情同步方案中,对皮尔拉克母羊施用 Toryum 可能会提高妊娠率。通过综合研究可以更好地理解 Toryum 与母羊生育参数之间的关系。
