The present study evaluated the effects of omega-3 (ω-3) fatty acid-rich linseed supplementation on reproductive performance, endocrine profile, and biochemical profile ewes reared in subtropical climates. Forty-eight acyclic clinically healthy Marwari sheep, aged 1.5–2.5 years with no parity, were divided into four groups ( n = 12 each). Ewes control group (group I) fed only a basal feed, whereas treatment II, III, IV diet along 10%, 15%, 20% linseed, respectively, daily dry matter basis. experiment was conducted during typical breeding season (October–November) sheep. estrus induction rate significantly higher p < 0.05) all than group. interval lower III. conception I 0.05). In addition, had lambing groups. Serum progesterone concentrations differed between days 15, 30, 45, 60 supplementation. On 15 serum estrogen compared to that I. groups, monounsaturated acid (MUFA) decreased 0.05), polyunsaturated (PUFA) increased from day onward. conclusion, by providing 15% dietary ewes, their performance can be improved Future studies are recommended further elucidate role sheep reproduction
