A Retrospective Study of Arabian Stallion Fertility Used in National Stud Farm of Tiaret (West of Algeria)

Abstract

The aim of this paper to evaluate the stallion fertility in advance and to aid breeding management. The collection of a historical information about the Arabian stallions adults (n=101) and 495 mares with range age between (8 and 26) years in the national stud farm of Chaouchoua Tiaret. Fertility was measured using three endpoints: foaling rates (FR), percent pregnant per cycle (PC) and percent pregnant per season (PR) during (2003-2013).The pregnant per season rate (PR) was of 84 % The foaling rate (FR) was of 80%, the pregnancy cycle rate (PC) was of 96 % ; a strong correlation existed between the number of mares mated and (PC) (r= -0.59; p<0.01). We conclude that breeding records existed in many forms (foaling, pregnancy per cycle, or per season rates), but there is still a need to develop tests that can predict fertility with a reasonable degree of certainty before the stallion has begun his breeding career.
