Age and weight at first mating affects plasma leptin concentration but no effects on reproductive performance of gilts
The objective of this study was to verify the best mating age of gilts at the first parity. Gilts (n = 86) were divided into nine groups in a factorial arrangement with three Ages (AG1, ≤ 220 d; AG2, 220 to 240 d; AG3, 240 ≤ d), and three weights (WT1 ≤ 140 kg; WT2, 140 to 149 kg; WT3, 150 ≤ kg).

description | The objective of this study was to verify the best mating age of gilts at the first parity. Gilts (n = 86) were divided into nine groups in a factorial arrangement with three Ages (AG1, ≤ 220 d; AG2, 220 to 240 d; AG3, 240 ≤ d), and three weights (WT1 ≤ 140 kg; WT2, 140 to 149 kg; WT3, 150 ≤ kg). A higher body weight gain in AG2 sows during gestation. Sows in AG2 group showed a higher body weight gain at first parity and backfat gain in the parity 2 and 3 during gestation. A greater insulin–like growth factor-1 (IGF-1) was observed in AG1 sows compared with AG3 sows at weaning in the second parity. Sows in WT1 group showed a significant positive effect on the plasma IGF-1 at breeding and weaning time in parity 2. Sows in AG3 group showed a higher plasma leptin at breeding, farrowing, and weaning in the parity 1, and at farrowing in parity 2. Sows in WT3 group showed a higher plasma leptin at breeding, farrowing, and weaning in the parities 1 and 2. Considering the insignificant longevity results, the most efficient time for gilts insemination can be at 220 d when their body weight is 140 kg or lower. |
