- Abstract
The aim of the experiment was to study the effect of fermented tea with different levels of Aspergillus niger on growth performance, nutrient apparent metabolic rate and serum antioxidant of Partridge shank chickens. A total of 240 one-day-old healthy chickens with similar body weight were randomly divided into four groups with three replicates per group and 20 chickens per replicate. Chickens in control group were fed with basal diet, and chickens in three experimental groups were fed with basal diet supplemented with 2%, 4% and 6% Aspergillus niger fermented tea, respectively. The experiment lasted for 56 d. The results showed that the use of Aspergillus niger to ferment tea increased the nutritional value of tea and decreased the tannin content. From 1~28 d of age, the average daily gain of chickens in group Ⅰ and group Ⅱ was significantly higher than that in control group ( P<0.05), and the feed to gain ratio of chickens in experimental groups was significantly lower than that in control group ( P<0.05). From 1~56 d of age, the average daily gain of chickens in group Ⅰ was significantly higher than that in control group ( P<0.05), and the feed to gain ratio was significantly lower than that in control group ( P<0.05). The EE apparent metabolic rate of chickens in group Ⅱ was significantly higher than that of control group ( P<0.05). The activity of T-AOC, T-SOD and GSH-Px in serum in all groups were significantly higher than those in control group ( P<0.05). The content of serum TG and TC in group Ⅰ and group Ⅱ were significantly lower than those in control group ( P<0.05). The study indicates that adding 2%~ 4% Aspergillus niger to the diet of Partridge shank chickens is more suitable for tea fermentation.
