Reproductive characteristics of foal heat in female donkeys / A. Carluccio, A. Gloria, D. Robbe, M.C. Veronesi, I. De Amicis, F. Cairoli, A. Contri. - In: ANIMAL. - ISSN 1751-7311. - 11:3(2017), pp. 462-465. [10.1017/S175173111600183X]
Abstract:
In this study, the first postpartum heat, termed the foal heat, characteristics and performance in female donkey (jenny) of Martina
Franca are described. To this end, the follicular development of 42 jennies during foal heat was compared with that of 31 jennies
at the third estrus after foaling. Estrus length (7.1 ± 0.9 and 6.8 ± 0.7 days), follicular development and preovulatory follicle size
(43.7 ± 3.5 and 45.1 ± 2.5 mm) were similar between jennies during the foal heat and during the third estrus after foaling. The
pregnancy rate at day 14 was significantly lower in the foal heat jennies (57.1%) than the third estrus jennies (82.3%). However,
the pregnancy rate at day 14 in foal heat jennies increased significantly when the onset of foal heat was ⩾8 days after foaling
(93.8%) or when the ovulation happened ⩾12 days after foaling (85.7%). The data provided in the present study suggest that the
foal heat in the endangered jennies of Martina Franca could be successfully utilized to reduce the interpartum period if the onset of
foal heat occurs >8 days after foaling.
