ABSTRACT
Asgari Safdar AH, Dayyani N, Moradi Kor N., Effect of fatty
acids on reproduction and blood hormones in Ashwari
ewes, Onl J Vet Res., 18(5): 432-437, 2014. Four groups of 12 flushing Ashwari ewes each were
fed 14 days a basal ration with grain,
5% calcium salts of fatty acids (CSFA) from flaxseed oil, or 5% CSFA
from sun flower oil. Controls were fed a basal diet. The first three diets
appeared to improve lambing rates. Ewes given CSFA from flaxseed had the
highest progeny with 18 lambs whereas controls had 10 lambs. Progesterone and
cholesterol levels in sheep given CSFA from flaxseed oil were higher than other
groups. The findings suggest that dietary CSFA may increase hormones related to reproductive performance.
Key words: CSFA, flushing, lambing rate, reproductive
performance, Afshari ewe.
