Effect of Acidifier on Performance and Serum Biochemical Indices in Fur Ring Minks

The study investigated the effects of phosphoric, citric, and lactic acid on the performance and serum biochemical indices of 100 black male minks. The minks were divided into 10 groups, with different acidifier levels tested. The results showed that acidifiers significantly reduced the pH of the diet and gastric juice, with citric acid being the least effective. The group receiving 1.5% lactic acid had a higher slaughter weight compared to the control group, and group Ⅳ had the longest body length. There were significant differences in spleen and kidney weights, but not in heart and liver weights. Serum BUN and IgA levels varied significantly among groups, with groups Ⅳ, Ⅰ, and Ⅹ showing the highest levels. The study concluded that 1.5% lactic acid was the most effective in improving production performance and maintaining visceral health during the hair growth period in minks.
