Control of the sexual cycle in Red Bilbilita ewes in seasonal anoestrus



Control of the sexual cycle in Red Bilbilita ewes in seasonal anoestrus



ITEA, Revista de la Asociacion Interprofesional para el Desarrollo Agrario 17(62): 57-68



254 Red Bilbilita ewes were given FGA-impregnated sponges for 14 days and were injected with 500 IU PMSG (groups 1 and 3; 40 and 48 ewes resp.) or 700 IU PMSG (groups 2 and 4; 37 and 49 ewes) on sponge removal, or received no further treatment (group 5; 80 ewes). Of ewes in the 5 groups, 57.5, 43.24, 62.5, 42.86 and 31.25% resp. conceived to mating during their 1st oestrus, with an overall CR of 67.50, 56.76, 75.0, 61.22 and 31.25%, and a lambing rate of 144, 138, 133, 133 and 108%.
