Day 49

The lambs were weighed on June 12. For the past 21 days, gain ranged from 4.8 to 24.2 lbs. and averaged 14.8 ± 3.9 lbs. The median gain was 15.2 lbs. The 21-d ADG ranged from 0.229 to 1.15 lbs. per day and averaged 0.706 ± 0.187 lbs. per day. The median ADG was 0.724 lbs. per day. One lamb (ram lamb) lost weight since the last weighing on May 22.

For the 49 day duration of the project, ADG ranged from 0.192 to 1.07 lbs. per day and averaged 0.704 ± 0.142 lbs. per day. The median ADG is 0.722 lbs. per day. The ram lambs and short-scrotum "rams" are gaining similarly, about 7% more than the wether lambs.

So far, no lambs have required anthelmintic treatment.
