Abstract


The experiment was carried out in “Posto Experimental de Ovinos e Caprinos do Instituto de Zootecnia de Itapetininga (SP)” to study the effect of active immunization with bovine follicular fluid (bFF) on Ideal and Sufflolk x Ideal ewes prolificity rate reared in subtropical climatic conditions.
The experiment was entirely randomized, beirg 2 treatments: controle (n=30) and immunized (n=30) ewes and 2 breeds Ideal and Sufflolk x Ideal. From 30 treated ewes with bFF 29 (96,7%) presented immunological response. Otherwise, immunization have no effect (P>.05) on fertility rate or oestral behavior. Average prolificity rate of immunized ewes (1,3) was higher (p<.05) than controle (1). Both breeds were similiar (P>.05) on prolificity rate, but occurried immunization effect (P<.05) in Suffolk x Ideal ewes. This difference was because of higher gemelar parturition number of immunized ewes (33%) against controle (0%).
The results of present study suggest that immunization against bFF offers alternative method to increase the birth number of ewes which have low prolificity, reared in subtropical climatic conditions.
