Evaluation of Mannanoligosaccharide (Bio-Mos®) and Esterified Glucomannan (MTB-100 ®) Dietary Supplementation on Growth Performance, Serum Parameters and Rumen Ecology of Barki Lambs under Egyptian Environment

A total of forty five fattening Barki lambs (15 animal/treatment) were fed on one customized complete pelleted basal diet (control) to which mannanoligosaccharide (MOS, Bio-Mos®) and esterified glucomannan (EGM,MTB-100 ®) were supplemented at level of 1 kg/ton in a four months experiment. Dietary supplementations of the diet with MOS as well as EGM had a positive effect on body weight development and % of body weight gain. The EGM- supplemented group had demonstrated significant increase in the serum globulin compared to control and MOS- fed groups. The results also revealed a non significant difference in rumen fluid ecology (Score, pH, ammonia nitrogen and total volatile fatty acids, TVFAs)In conclusion both of the additives used (Bio-Mos® and MTB-100 ®) have a positive effect on growth performance parameters with no adverse effect of rumen ecology when included to fattening Barki lambs diet under Egyptian environment.
