Abstract
Background: Majority of the sheep farmers in our country (semi arid region) do not supplement with concentrate feed even in critical
physiological stages. It was observed that concentrate supplementation in addition to free grazing substantially improved production
performance of ewes and lambs.
Methods: In this study the parameters such as conception rate, birth weight of lambs, fortnightly body weight changes, rumen
fermentation pattern and blood parameters were recorded.
Result: Out of twenty sheep in each group 16, 18 and 19 were exhibited oestrous symptoms and the percentage of heat observed
were 80, 90 and 95 in the G1, G2 and G3, respectively. The numbers of animals conceived were 12, 14 and 17 and the conception
percentage was 75, 77 and 89. The concentrate supplemented group showed higher conception rate. The numbers of lambs born
were 12, 14 and 17 and the lambing percentages were 75, 78 and 89 for the G1, G2 and G3, respectively. The rumen pH was found
to be decreasing in G3 group followed by G2 group when compared to G1 group whereas, the production of VFA was found to be
higher in G3 group followed by G2 group when compared to G1 group. There were increased levels of total nitrogen, TCA nitrogen and
NP nitrogen in sheep at 4 hours after feeding of concentrate feed in G3 group followed by G2 group when compared to G1 group. The
results indicated that the higher levels of blood glucose, triglycerides, cholesterol and BUN were observed in G3 group followed by G2
group when compared to G1 group.
