A Big Improvement

There was a big improvement in the goats today. Weight gains weren't as high as we hoped, but FAMACHA© scores improved, fewer goats required deworming, and fewer goats had diarrhea. Most of the goats presented with full bellies.

For the past two weeks gained, ranged from -7.4 to 5.6 lbs. and averaged 1.3 + 2.3 lbs. The median gain was 1.2 lbs. Average daily gain (ADG) ranged from -0.53 to 0.40 lbs. per day and averaged 0.09 + 0.17 lbs. (41 + 186 g) per day.  The median gain was 0.086 lbs. (39 g) per day.

For the period, the top gaining goat was #383 (Zink, IN). Eight additional bucks gained more than 4 lbs. for the period:  #'s 301 (Loos, IL); 305 (Adams, IL); 351, 353, and 354 (Pinneo, KS); 375 and 376 (Weber, IL); 388 (Burke, DE),

For the first 42 days of the test, average daily gain ranged from -0.286 to 0.274 lbs. per day and averaged 0.053 + 0.089 lbs (24 + 40 g) per day. The top-gaining buck is #375 (Weber, IL).

Only two other bucks are gaining more than 0.20 lbs. per day:  #376 (Weber, IL) and #388 (Burke, DE).  Over 75 percent of the bucks have gained weight during the first 42 days of the test, despite the significant parasite challenge.

FAMACHA© scores ranged from 1 to 5 and averaged 2.6 + 0.6, compared to 2.9 + 0.9 two weeks ago.  The median FAMACHA© score was 3. Nineteen goats were dewormed with either levamisole or moxidectin.  If a goat was previously given levamisole, it was given moxidectin. There were only two goats with FAMACHA scores of 4 or 5.

This week, not all goats with FAMACHA© scores of 3 were dewormed.  If a goat's FAMACHA© score had worsened from its previous score, it was dewormed, especially if it had a high fecal egg count on July 11. If a previously treated goat's FAMACHA score had improved to 3, it was not dewormed, especially if it had a positive weight gain.

Body condition scores improved slightly averaging 2.3 + 0.3.  Dag and fecal consistency scores also improved, with fewer goats having diarrhea. Scours had been weakening anemic goats and made it difficult to obtain fecal samples.

For the past two weeks, the goats have been grazing two, 2-acre paddocks of dwarf sorghum grass. So far, they have been evenly grazing the top canopy of the sorghum.  Parasite re-infection should be minimal over the next several weeks, giving the goats ample opportunity to gain weight and rebuild their blood supplies. This week's weather (80's) has also been favorable to the goats.
