[Combined effects of injected 1-29 GRF and diet energy level in lactating goats].
Subcutaneous injections of 1-29 GRF and diet energy level were studied in 48 dairy goats using a 2 x 2 factorial design. Energy and GRF effects were additive on milk production and some interactions were observed on the milk fat and protein contents. Subcutaneous injections seemed to be less efficient in promoting milk secretion than the intravenous route used in a previous trial.
