Incidence of Repeat Breeding Syndrome in Cattle from Four Local Government Areas of Adamawa State, Nigeria

Abstract

Repeat breeding syndrome is a multi-factorial condition, which has become a major source of economic waste in the cattle industry due to the need for more inseminations or services, increased calving interval, reduced milk production and increased culling rates. The study investigated the incidence of repeat breeding syndrome in cattle and determined the progesterone profile of repeat breeders in four Local Government Areas of Adamawa State, Nigeria. One hundred herds were sampled during the study and fifty-seven repeat breeders were identified. The proportions of repeat breeding syndrome within the four Local Government Areas were given as 1.59, 1.28, 1.49, and 1.71% for Girei, Yola North, Yola South, and Fufore respectively. The overall incidence was 6.08%. Seven of the repeat breeders were pregnant, ten cyclic and forty non–cyclic. There was no significant variation in the progesterone profile of the non-cyclic repeat breeders during weeks 1 and 2 (p>0.05) and 2 and 3 (p>0.05). However, there was significant variation during weeks 1 and 3 (p<0.05). The progesterone concentration of the pregnant repeat breeders was not significantly varied during weeks 1 and 2 (p>0.05), varied significantly within the weeks 1 and 3, at 51.5±0.8944 and 50.2±0.089ng/l (p<0.01) respectively and 2 and 3 (p<0.014). The progesterone levels of the cyclic animals were extremely varied within weeks 1 and 2 (p<0.001); 1 and 3 (p<0.001) and 2 and 3 (p<0.001).
