After 66 Days

Over the last two weeks, the lambs gained an average of 0.284 ± 0.286 lbs. per day. For this weigh period, the lambs in the supplemented group (n=37) had a higher ADG than the lambs in the non-supplemented (pasture) group (n=35):  0.449 ± 0.228 vs. 0.115 ± 0.239 lbs. per day.

For the 66 days of the study, ADG has ranged from 0.145 to 0.591 lbs. per day and averaged 0.386 ± .084 lbs. per day. After today's weighing, the lambs in the supplemented group surpassed the lambs in the non-supplemented group in ADG: 0.417 0.071 vs. 0.355 ± 0.085 lbs. per day. 

For the samples collected on August 17, fecal egg counts ranged from 0 to 3475 epg and averaged 371 ± 500 epg.  FAMACHA©  scores improved from August 17 until August 31, averaging 1.6 and 1.8, respectively for the supplemented and non-supplemented groups. 

Body condition scores declined an average of  0.3 points in the non-supplemented lambs. They stayed constant in the supplemented group. More lambs had positive dag scores and scours was noted in several lambs. The change in fecal consistency was attributed to the increased moisture in the forage. Rainfall has been substantially higher over the past few weeks.
