| Abstract | ||
| The two primary polysaccharides found in yeast cell wall (YCW), which is frequently added to animals' diets as a nutritional supplement, are mannan-oligosaccharide and β-glucan. The effect of yeast cell wall (YCW) additive on goat kid’s growth performance was investigated using twenty-four growing Baladi male goats, weighing 8.33 ± 0.05 kg and an average age of three months. The kids were assigned to four similar groups according to weight and age, each with six kids, and fed a total mixed diet that included 60% concentrate feed mixture, 25% corn silage, and 15% alfalfa hay. For G1, G2, G3, and G4, the experimental groups were given the entire mixed diet with YCW at 0, 5, 7.5, and 10 g/head/day, respectively. Compared to the control group, the addition of YCW resulted in a notable improvement in all nutrient digestion, nutritional values, rumen fermentation, blood serum biochemicals, feed intake, growth performance, feed conversion ratio, and economic efficiency. Group 3, which was given 7.5 grams/head/day, achieved the highest results of digesting all nutrients, nutritional values, concentrations of total volatile fatty acids, acetate, and propionate in the rumen, total protein, albumin, globulin, and glucose in blood serum, final live body weight, total body weight gain, average daily gain, feed conversion ratio, and economic efficiency. Also, dry matter (DM), total digestible nutrients (TDN), crude protein (CP), digestible crude protein (DCP), and total and net revenues were all higher in G3 (P<0.05). But the rumen's pH, ammonia-N, and butyrate concentrations were significantly lower in G3, and the blood serum's triglycerides, cholesterol, urea nitrogen, creatinine, alanine aminotransaminase (ALT), and aspartate transaminase (AST) concentrations were significantly lower in G3 (P<0.05). In conclusion, adding 7.5 g/kid/day of YCW in diets of growing kids revealed the beast results, which had a significant positive impact on blood serum biochemicals, digestion, rumen fermentation activity, feed intake, growth performance, feed conversion, and economic efficiency. | ||
