Abstract
Descrevem-se os aspectos qualitativos do sêmen e a fertilidade de um garanhão da raça PSI (Puro Sangue Inglês), durante cinco períodos reprodutivos (1990 a 1994). Verificaram-se altos índices de acrossomo anormais (13,6 a 39%) nos ejaculados (N° = 15), na maioria do tipo "Knobbed AcrosomeDefect" (área hipercromática ou espessamento excêntrico apical dos espermatozóides afetados. A porcentagem de prenhez (P) variou entre 25 e 90% e a porcentagem de prenhez por ciclo (P/C) entre 20 e 59%. Através de análise de regressão, P/C relacionou-se significativamente (p<0,05) com os índices de acrossomos anormais (R²=0,87). As demais características seminais avaliadas, não se relacionaram aos índices de fertilidade. Conclui-se que o defeito de acrossomo, neste caso, podem ser atribuídas à espermiogênese imperfeita. Tal anormalidade afeta significativamente a fertilidade do garanhão.
It is described certain qualitative seminal characteristics and the fertility of a Thoroughbred stallion, during five consecutive breeding seasons (1990 a 1994). High percentages (13.6 a 39%) of abnormal acrossomes were observed in the ejaculates (N° = 15), being the majority of the "Knobbed Acrosome Defect" type (dark staining area or eccentric thickening at the apex of affected spermatozoa). The pregnancy rate (P) varied between 25 e 90% and the per cycle pregnancy (P/C) between 20 e 59%. Regression analysis showed that P/C was significantly (p<0.05) related to the percentage of abnormal acrossomes (R²=0.87). Other seminal characteristics considered in this report were not associated (P>0.05) to fertility indexes. The conclusion is that the acrossomal defect, in the present case, could be attributed to arrested spermiogenesis. Such abnormality significantly affected stallion fertility.
