摘要: To determine the effect of energy and protein intakes on boar libido, semen characteristics, plasma hormone concentrations, 24 crossbred boars (1 yr age) were allotted to one three dietary treatments. Two levels (7.7 18.1 g/d lysine) two (6.1 7.7 Mcal/d ME) combined create 1) low-energy low-protein (ep), 2) high-protein (eP), 3) high-energy (EP) Semen was collected times per week for 27 wk. During wk 28, blood samples before after a intravenous injection GnRH (375 ng/kg BW). The EP had higher (P .10).(ABSTRACT TRUNCATED AT 250 WORDS)
