Redberry juniper as a roughage source in lamb feedlot rations: Performance and serum nonesterified fatty acids, urea nitrogen, and insulin-like growth factor-1 concentrations

Effects of replacing cottonseed hulls with dry redberry juniper leaves on performance and serum NEFA, urea N, and IGF-1 were investigated in Rambouillet lambs (n = 24, initial BW = 28.6 ± 4.94 kg). In a study with 2 feeding periods (period 1 = 65% concentrate ration, 28 d; period 2 = 85% concentrate...
