Effects of live yeast culture addition into sucrose supplemented diet on fattening performance, some blood and histological parameters in saanen male kids fed without forage

Abstract

Summary: The aim of this study was to evaluate the effects of live yeast culture (LYC) as a feed additive on fattening performance, and some blood and rumen fluid parameters in male goats fed with sucrose (SU) supplemented diet. Totally 18 male Saanen goat kids were divided into three groups, no SU and no LYC (C) as control group, 3% SU (S) and 3% SU with LYC (S+LYC) as the treatment groups, each containing 6 kids. Diets of groups were formulated as isonitrojenic and isocaloric. LYC (Rumisacc, 344x1010 cfu per gram) was included in the diet at 2% on feed basis. Feeding schema was established with no roughage, diets were given ad libitum, and the kids in each group were fed individually. In the experiment, ruminal ammonia-N increased and ruminal pH decreased in sucrose supplemented diet consumed groups (p<0.05) regardless of the supplementation of live yeast culture. Dietary sucrose with live yeast culture supplementation did not significantly affect fattening performance and blood parameters, except hemoglobin. Dorsal and ventral rumen papillae lengths were not affected by dietary treatments. Keratin layer of sucrose supplemented group (S) was increased when compared with control group (p<0.05).
