No gain

After robust gains last time, the goats (on-average) did not gain any weight during these past two weeks, though individual goats gained and loss weight. After grazing the sorghum grass for more than four weeks, the goats had moved back to grazing the cool season grass paddocks.

During the past two weeks, gain ranged form -5.6 to to 4.8 lbs. and averaged -0.056 + 2.15 lbs. The median gain was 0.1 lbs. ADG ranged from -0.431 to 0.286 lbs. per day and averaged -0.004 + 0.165 lbs. per day. The median ADG was 0.008 lbs. per day. For the period, the top-gaining goat was #303 (Adams, IL).

For the 70-day duration of the test, ADG is ranging from -0.151 to 0.286 lbs. and is averaging 0.096 + 0.070 lbs. per day. The median ADG is 0.097 lbs. per day. As of day 70, two goats are tied for having the highest rate-of-gain:  #303 (Adams, IL) and #375 (Weber).

Only two additional goats are gaining more than 0.20 lbs. per day:  #376 (Weber) and #312 (Barnes). Three more goats are gaining more than 0.19 lbs. per day: #351 (Pinneo, KS), #376 (Weber), and  #381 (Zink, IN).

FAMACHA© scores declined. They ranged from 1 to 4 and averaged 2.3 + 0.6, compared to 2.1 + 0.5 two weeks ago. Only two goats required deworming. They had FAMACHA© scores of 4.

Eighteen additional goats with FAMACHA© scores of 3 were dewormed with levamisole. The 3's were dewormed due to the risk posed by the cool season paddocks.  Not enough time has lapsed since they were last grazed; they are likely still contaminated with infective 3rd stage worm larvae.

Dag scores and fecal consistency scores improved slightly. No goat had active diarrhea. As a result, fecal samples could be obtained from every goat in the test. A pooled fecal sample was collected from random goats. It will be used to determine worm species. Body condition scores remained unchanged, averaging 2.2 + 0.3.

The goats were scanned today to determine their rib eye areas. Ultrasound scanning was done by Jim Pritchard from West Virginia University. Jim is probably the most experienced scanner of goats in the United States. The images will be interpreted by the National CUP Lab & Technology Center in Ames, Iowa.

The goats were worked a day early, due to a conflict with the Maryland State Fair. They will be worked for a final time on Thursday, September 5. They will be weighed two days in a row to determine their final weights.

In addition, the goats will be evaluated for reproductive soundness (teats, testicles) and structural correctness (feet, legs, hooves, bites). To qualify for the sale, bucks must meet minimum standards for reproductive soundness and structural correctness.
