|Rounding the lambs up for weighing|
For the third weigh period, gain ranged from 0.8 to 10.8 lbs. for an average of 6.6 ± 2.0 lbs. and a median of 6.8 lbs. Looking at it another way, average daily gain (ADG) ranged from 0.057 to 0.771 lbs. per day and averaged 0.472 ± 0.145 lbs. per day. The median ADG was 0.486 lbs.
No lamb lost weight during the past two weeks. One lamb was dewormed (with moxidectin; Cydectin @ 1 ml/11 lbs.) because it had a FAMACHA© score of 3 and failed to meet its gain objective (70% x 0.6 lbs. per day). The rest of the lambs had FAMACHA© scores of 1 or 2, mostly 1.
For the third weigh period, the ram lambs (n=19) gained an average of 0.469 ± 0.143 lbs. per day. Their median ADG was 0.486 lbs. per day. The wethers (n-24) gained an average of 0.457 ± 0.112 lbs. per day. Their median ADG was 0.464 lbs. per day. The short-scrotum lambs (n=17) had the highest, but most variable ADG: 0.496 ± 0.187 lbs. per day. Their median ADG was 0.514 lbs. per day.
For the first 35 days, ADG has ranged from 0.267 to 0.814 lbs. per day and averaged 0.560 ± 0.105 lbs. per day. The median ADG is 0.567 lbs. per day. No lamb has lost weight. So far, the ram lambs are gaining 0.551 ± 0.108 lbs. per day. The wethers have gained slightly less: 0.550 lbs. ± 0.119 per day. The short scrotum lambs have the highest 42-d ADG: 0.586 ± 0.081 lbs. per day. At this point, it is not known if any of these differences are statistically significant.

A five acre paddock of dwarf pearl millet was recently planted and has emerged. It will be available for grazing later in the summer.The project will end in mid-August, with the harvest of the lambs.
