Neurotransmitter effect of galanin on the mean plasma concentrations of growth hormone, triiodothyronine, thyroxine, and milk protein in dairy goats sannan

This study investigated the effects of five levels of galanin on plasma concentrations of growth hormone, triiodothyronine, thyroxine, and milk protein in dairy goat breed was sannan. 15 breeds of dairy goats sannan all about the same age and weight were selected for this study and were randomly divided into five treatments (three replicates per treatment). Levels of the hormone injection of galanin in the experiment (0, 0.2, 0.4, 0.8, 0.16) (µg/ml galanin hormone per kilogram of body weight), respectively. Finally, experimental growth hormone was increased hormone galanin (P < 0/05). But a depressing effect on plasma concentrations of thyroid hormones triiodothyronine and thyroxine were not found to be statistically significant (P > 0/05). This hormone also reduced the percentage of protein, which was not statistically significant (P > 0/05).
