This study aimed to investigate the effects of adding different doses of garlic powder (GP) into milk on the growth and health parameters of Holstein calves. Thirty Holstein calves were randomly divided into groups as follows: control (CON), T1 (10 mg GP/kg live weight (LW)), and T2 (30 mg GP/kg LW). Four days old calves were used as animal material. The calves were weaned when they consumed 800 g of starter for 3 consecutive days. The experiment was terminated when the calves reached 8-week age. Starter and water were available ad libitum. Both GP doses significantly decreased respiratory score, the number of illness days, and diarrheal days ( 0.05). In addition, a significant improvement was observed in the general appearance of calves that received both GP doses ( 0.05). Garlic powder created a significant decrease in oxidative stress index at 28 days old and total oxidative status at the end of the experiment ( 0.05). Garlic powder was not significantly effective for the inhibition of pathogenic bacteria growth at the 28-day-old and the end of the experiment. The application of 30 mg/kg LW GP significantly reduced the incidence of cases such as diarrhea and respiratory diseases, which are common during the suckling period.
本研究旨在探讨在牛奶中添加不同剂量大蒜粉（GP）对荷斯坦犊牛生长和健康参数的影响。将 30 头荷斯坦犊牛随机分为以下几组：对照组（CON）、T1 组（10mg GP/kg 活重（LW））和 T2 组（30mg GP/kg LW）。4 日龄犊牛作为动物材料。当犊牛连续 3 天每天消耗 800g 开食料时，犊牛开始断奶。当犊牛达到 8 周龄时，实验结束。开食料和水均自由采食。两种 GP 剂量均显著降低了呼吸评分、患病天数和腹泻天数（P<0.05）。此外，接受两种 GP 剂量的犊牛的一般外观均有显著改善（P<0.05）。大蒜粉在 28 天时显著降低了氧化应激指数，在实验结束时显著降低了总氧化状态（P<0.05）。大蒜粉在 28 天和实验结束时对抑制病原菌生长的效果不显著。应用 30mg/kg LW GP 可显著降低腹泻和呼吸道疾病等常见哺乳期病例的发生率。
