Impact of different levels of probiotics on blood and biochemical parameters of local goat kids

This study was conducted for 105 days, including 15 days preliminary period aimed to investigate the effect of adding different levels of probiotics and concentrate diets on blood characteristics and serum biochemical parameters of local Iraqi goat kids. The study included 18 males of local goats at the age of 3 months with an average weight of 16.17±1.10kg. The kids were randomly distributed into 6 treatments with two levels of 40, and 60% and three levels of probiotics of 0, 2.5, and 5g/head/day. The probiotics were Lactobacillus acidophilus (10⁸), Bacillus subtilis (10⁹), Bifidobacterium (10⁸, and Saccharomyces cerevisiae (10⁹). The addition of the probiotic led to a significant increase in the level of glucose in the blood serum from 82.21mg/100 ml for the group of kids fed a 40% concentrated diet to more than 90.0mg/100 ml for the kids fed a 60% concentrated diet and to which a probiotic is added 2.5 or 5g/head/day. A significant decrease in cholesterol concentration was found in groups fed a concentrated diet of 60%. Triglycerides elevated from 23.86mg/100ml of kids fed 40% concentrate and 2.5mg probiotics/head/day to 29.17mg/100ml of kids fed 60% concentrate and 2.5g probiotics/head/day. In conclusion, the addition of the probiotic at the two levels 2.5 or 5g/ head/ day improved the biochemical and blood parameters of the animal.
