Effect of using natural non-traditional growth promoters: 2- effect of Fenugreek and Monensin as growth promoters on beef steers performance
Abstract: Fifteen baladi calves at eight months of age were randomly divided into three groups, 5 animals each. The initial average live body weight values were 206.8, 205.6, and 206.4kg for groups 1, 2 and 3respectively. Three complete rations were formulated from concentrates mixture (65%), wheat straw (30%) and molasses
(5 %). The first ration had neither monensin nor fenugreek and served as control, while second and third represented rations were supplemented with monensin (125 mg/h/d) or fenugreek seeds (3%) respectively. The experimental period lasted for 180 days followed by ten days digestibility trial. Results obtained indicated that monensin and fenugreek fed groups were (p<0.05) higher in final body weight, total gain and average daily gain compared with control group. Groups fed monensin and fenugreek rations showed (p<0.05) less kg of DMI, DCPI, TDN/kg gain as well as less
TDNI kg/h/d, TDNI kg/100kg LBW, TDNI kg/w75 DEI Mcal./h/d DEI Mcal./100kg LBW, DEL Mcal./W75, and CPI/h/d, DCPI/h/d, DCPI g/100kg LBW, DCPI g/kgW75, and CPI/h/d, DCPI/h/d,DCPI g/100kg LBW, DCPI g/kgW75 compared with control. No significant differences were found among tested groups in digestibility of DM, OM, CP and CF. On the other hand fenugreek group and the control had (p<0.05)higher EE digestibility compared with monensin group. Fenugreek group had (p<0.05)higher NFE digestibility compared with control and monenesin groups. No significant differences found among three tested groups in rumen NH3-N. However, fenugreek group recorded the lowest values of rumen NH3-N. Also differences among treatments in pH and molar proportion of TVFA,s production were insignificant Acetic acid, propionic acid and butyric acid molar proportion production for the three tested group showed that control group had (p<0.05) higher acetic acid production compared with other groups at all sampling time. On the other hand, monensin and fenugreek fed groups showed higher (p<0.05) production of propionic acid compered with control. While no significant differences were found among treatments in butyric acid production. No significant differences were found among treatments in T.P.,AL., GL. GOT and GPT while monensin fed group had (p<0.05) higher value of Urea compared with fenugreek and control fed groups. The best economical return was achieved by the group fed ration contained fenugreek followed by the group fed ration contained monensin and the lowest was the control.
