SAUNDERS, G.A. et al. Effect of the nutritional level before and after ovulation on pregnancy rate and prolificacy in Santa Ines ewes. Arq. Bras. Med. Vet. Zootec. [online]. 2012, vol.64, n.5, pp.1085-1093. ISSN 0102-0935.

Forty-tree ewes were assigned to four treatments in a randomized block design. The treatments consisted of two flushing diets, composed of soybean meal (SMF) or corn gluten and cottonseed meal (CG+CMF) furnished for 28 days before ovulation, and feeding with flushing diets or a maintenance diet (MD) for 28 days after ovulation: T1 - (SMF) before and after ovulation (n=12); T2 - SMF before ovulation and a MD after (n=11); T3 - CG+CMF before and after ovulation (n=10); T4 - CG+CMF before ovulation and MD after (n=10). The gain in BW and the final BW did not differ (P>0,05) between treatments. The final BC was higher (P>0,05) in ewes in T3 treatment than in those in treatment T2. The urea N concentration was higher (P<0,05) in ewes in treatments T1 and T3 than those in treatments T2 and T4. The pregnancy rate and prolificacy did not differ (P>0,05) between treatments. The flushing diets before ovulation and feeding with this same diet or a maintenance diet after ovulation did not alter the pregnancy rate and prolificacy.

Keywords : Soybean meal; corn gluten; degradable rumen protein; plasma urea N concentration.
