摘要: Cyclic females actively immunized against growth hormone-releasing factor (GRF; n = 5) or human serum albumin (HSAi; 4) were used to determine the effects of reduced somatotropin (ST) and IGF-I on metabolism production in gestating lactating sows. Sows farrowed, pigs weaned at 28 d lactation, sows observed for estrus after weaning. Blood samples collected 15-min intervals 5 6 h 110 gestation 21 lactation. Mean ST (nanograms/milliliter) was less (P < .05) GRFi than HSAi but it similar gestation. Serum concentrations lactation not thyroxine greater during GRF weighed .01) had more backfat sows; vitro glucose oxidation lipogenic rate adipose tissue .05 treatment x day interaction) Across treatment, mammary gland clearance rates increased .05), whereas utilization decreased During mobilized did controls.(ABSTRACT TRUNCATED AT 250 WORDS)
