Abstract:
The objective of the present study was to investigate whether adding condensed tannins (T) to the diet of sheep increases ovulation rate (OR). In all, 281 mature Polwarth ewes (49.9 #1; 6.0 kg and body condition score (BCS) of 2.02 #1; 0.24 units) were heat-synchronised (oestrus = Day 1) and sorted in the following four treatment diets: (1) native pasture alone (82.6 g of CP and 8.4 MJ metabolisable energy (ME)/kg DM) (NP; n = 70); (2) native pasture (NP) plus a supplement of 0.45 kg of soybean meal (S) from Day 10 to Day 14 (NP+S; n = 71); (3) NP plus a supplement of 0.45 kg S and 25 g of T, to get an estimated concentration of T in the diet of 1.5% (NP+S+1.5T; n = 69); and (4) NP plus a supplement of 0.45 kg S and 42 g of T, to get a concentration of T of 2.5% (NP+S+2.5T; n = 71). OR was measured 8 days after the second heat by rectal ultrasound (Day 25). The estimated consumption of crude protein (CP) during the supplementation period was 129, 261, 237 and 200 g/ewe.day for NP, NP+S, NP+S+1.5T and NP+S+2.5T ewes, respectively. NP+S+1.5T ewes had an OR of 1.90, which was higher (P < 0.05) than those for NP+S+2.5T and NP+S ewes (1.68 and 1.70, respectively). All supplemented ewes had a higher OR than did NP ewes (1.48, P < 0.05). Although NP+S+1.5T ewes ate less protein than did NP+S ewes, their OR was higher, as a result of a more effective use of the protein. The higher concentrations of 2.5% T in the diet might have not evoked a response in OR. |
