摘 要:The objective of this study was to compare the effect of linseed and canola expeller on average daily weight gain(ADG),concentrate intakes,incidence of diarrhea,serum haptoglobin,interleukin(IL)-1,and resolvin-E1 in female Holstein calves from birth to weaning.A sample size of 20 calves per group was calculated and were randomly allocated at the time of *** group(LIN)was fed a starter with linseed expeller,while canola group(CAN)received a similar concentrate,but with canola *** expellers were included at a rate of 25%dry matter(DM)basis of the *** waste milk was fed twice a day until *** were weighed at birth,30,and 60 d of *** intake was evaluated daily from 5 to 60 d.A blood sample was obtained at birth,14,28,35,and 49 d of age,and bovine serum resolvin-El,haptoglobin,and IL-1 were assayed by commercial enzyme-linked immunosorbent assay(ELISA)*** of diarrhea and the duration of the events were also *** effect of the interaction group by time on body weight(BW)and starter intake was not significant(P0.05).Average daily gains(ADG)from 0 to 60 d for CAN and LIN groups were 0.680 and 0.675 kg/d(P0.05),*** of diarrhea were 25%and 45%for CAN and LIN groups,respectively(P=0.18).LIN group had greater concentrations of IL-1 at d 21,haptoglobin at d 7,and resolving-El at d 14 and 49 than CAN group,*** is concluded that BW at weaning,ADG,and concentrate intakes were not different between groups fed starters containing linseed or canola expeller(25%inclusion).The concentrations of cytokines and haptoglobin were the greatest in LIN group.
