摘要

目的是描述围产期繁殖能力强的杂交母猪的出生相关激素谱。研究人员检查了激素谱是否存在偏差,这取决于分娩过程(优产:难产)和住房类型(箱栏BS vs分娩栏FP vs群住房GH)。共有40头健康、妊娠期≥2的杂交母猪(德国长×大)。房屋类型间的分布为:BS n=18, FP n=15, GH n=7。所有的出生都发生在生理上完成的妊娠期之后。于产前第113天至产后第4天通过留置导管采血。测定孕酮(P4)、雌二醇(E2)、前列腺素F2α及其代谢物(PGFM)、松弛素、催产素、皮质醇、肾上腺素和去甲肾上腺素。顺产与难产之比为15:25。无论房型如何,难产都会发生。难产的唯一原因是弱产(分娩60分钟)。窝产仔数为17.73±3.85头。顺产与难产的激素谱差异如下:难产时P4增高p=0.0776;顺产时催产素增高(无统计学意义),12.5%的母猪永久性低氧血症;皮质醇p = 0.0503;去甲肾上腺素p = 0.0098。住房类型对激素谱的影响如下:P4 p=0.046;E2 p = 0.0009;PGFM p = 0.0108;松弛素p = 0.0022;去甲肾上腺素p = 0.0078。分娩相关激素与分娩和分娩时的住房类型有关。所获得的激素谱可用于猪围产期动物福利型住房系统的探讨。高增殖系的母猪在分娩II期出现永久性低氧血症的比例是显著的。顺产与难产的比例分布不均匀。无论房型如何,难产都会发生。

The parturition-relevant hormone profile in hyper-prolific sows under different housing conditions.

Aim was to characterize birth-relevant hormone profiles of reproductively productive hybrid sows in the peripartum period. It was examined whether there are deviations in the hormone profile depending on the birth process (eutocia:dystocia) and the type of housing (box stall BS vs. farrowing pen FP vs. group housing GH).A total of 40 healthy, heavily pregnant hybrid sows (German Landrace x Large White) with a gestation number≥ 2 were available. The distribution between the housing types was: BS n=18, FP n=15, GH n=7. All births occurred after the biologically completed gestation period. Blood samples were taken via indwelling catheters (113th day ante partum to 4th day post partum). Progesterone (P4), oestradiol (E2), prostaglandin F2α and its metabolites (PGFM), relaxin, oxytocin, cortisol, adrenaline and noradrenaline were determined.The ratio of eutocia:dystocia was 15:25. Dystocia occurred regardless of type of housing. The only reason for dystocia was a weak labor (>60 min). The litter size was 17.73± 3.85 piglets. Differences in the hormone profiles between eutocia and dystocia were as follows: P4 tended to be higher in dystocia p=0.0776; oxytocin higher in eutocia (not significant), 12.5% of sows permanently with hypoxytocinemia; cortisol p=0.0503; noradrenaline p=0.0098. The type of housing had the following influence on the hormone profile: P4 p=0.046; E2 p=0.0009; PGFM p=0.0108; relaxin p=0.0022; noradrenaline p=0.0078.The parturition-relevant hormones are related to the parturition and to the type of housing during birth. The hormone profiles obtained could be of use in the discussion about the animal welfare-oriented housing system in the peripartum phase in pigs. The proportion of sows of the hyperproliferative line studied with permanent hypoxytocinaemia in stage II of parturition is remarkable. The ratio of eutocia:dystocia is unevenly distributed. Dystocia occurred regardless of the type of housing.

期刊介绍: Die Tierärztliche Praxis wendet sich mit ihren beiden Reihen als einzige veterinärmedizinische Fachzeitschrift explizit an den Großtier- bzw. Kleintierpraktiker und garantiert damit eine zielgruppengenaue Ansprache. Für den Spezialisten bietet sie Original- oder Übersichtsartikel zu neuen Therapie- und Operationsverfahren oder den Einsatz moderner bildgebender Verfahren. Der weniger spezialisierte Tierarzt oder Berufseinsteiger findet auf seinen Berufsalltag zugeschnittene praxisbezogene Beiträge in der Fortbildungsrubrik „Aus Studium und Praxis“. Mit dem hervorgehobenen „Fazit für die Praxis“ am Ende jedes Artikels verschafft sich auch der eilige Leser einen raschen Überblick über die wichtigsten Inhalte dieser modern konzipierten Fachzeitschrift mit den vielen hochwertigen, überwiegend farbigen Abbildungen. In jedem Heft ermöglicht ein ATF-anerkannter Fortbildungsartikel den Erwerb einer ATF-Stunde (Akademie für tierärztliche Fortbildung).
