Значения термина average bw на английском

Twenty-two crossbred 6-wk-old castrated male pigs with an average BW of 9 kg were used.

In Trial 2, treatments with ramps had no difference in average BW; however, these groups consumed less feed, resulting in significantly lower feed:gain ratios.

During the experimental period of 10 d, the pigs were 11 wk of age with an average BW of 14 kg.
