Abstract

This experiment was conducted to study the effects of acidifier on performance and serum biochemical indices of racoon dogs. One hundred healthy male Wusuli raccoon dogs with similar body weight were randomly divided into 10 groups with 10 raccoon dogs per group. The control group (group Ⅰ) was fed a basal diet, and the experimental groups (groups Ⅱ to Ⅹ) were fed the experimental diets supplemented with 0.4%, 0.6% and 0.8% phosphoric acid, 0.5%, 1.0% and 1.5% citric acid, 0.5%, 1.0% and 1.5% lactic acid, respectively. The experiment lasted for 125 days. The results showed as follows: 1) compared with the control group, the acidifier had significantly effect on the pH of diet and gastric juice (P<0.01), the acidifier had no significantly effect on intestine juice pH (P>0.05), the dry matter intake was firstly increased and then decreased with the acidifier supplemented level increasing. 2) Compared with the control group, the acidifier had no significantly effects on body weight, average daily gain, carcass weight, body length, fur length and fur weigh (P>0.05). 3) There were no significant differences in the contents of urea nitrogen, glucose, immunoglobulin M, triiodothyronine and thyroxine in serum among all groups (P>0.05). Serum total protein content showed a negative correlation with phosphoric acid supplemented level, and it was firstly decreased and then increased with the citric acid and lactic acid supplemented levels increasing. Serum albumin content showed a decreased tendency with the citric acid and lactic acid supplemental levels increasing. Serum immunoglobulin G content showed a negative correlation with phosphoric acid and citric acid supplemented levels, and it was firstly increased and then decreased with the lactic acid supplemented level increasing. In conclusion, 1.0% lactic acid group can get the optimal effect under this experimental condition.
