Lactation activity, chemical composition, and in vitro metabolism of rat mammary tissue.

摘要: SummaryMammary tissue of rats at the end pregnancy and height lactation was analyzed for dry matter nitrogen content, metabolic rate this measured in vitro.Lactation increased water content mammary protein matter.Lactation did not affect per unit fresh vitro; it decreased tissue.Observations were also made on that suckled only 1-3 instead 6 young; measurements taken with young earlier stages before full milk production reached. These indicate a positive correlation between intensity magnitude effect has composition tissue.
