An experiment was conducted to determine the effect of algae-based antioxidant containing Se yeast (EconomasE®) on the growth performance, visceral organ weight, meat quality, and oxidative stability of broiler chickens.
Nine hundred sixty, day-old male broiler chickens (Cobb, 43.97±0.55 g) were divided into three dietary treatments and allocated into 12 deep litter pens in a completely randomized design giving 4 replicate cages for each treatment. Three dietary treatments were: i) control (CON, basal diet with sufficient nutrient), ii) vitamin E (VitE, basal diet supplemented with 100 IU VitE), and iii) Algae-based antioxidant containing Se yeast (EcoE, basal diet supplemented with 0.2% algae-based antioxidant containing Se yeast: EconomasE®). Maize soybean meal based basal diets were formulated to meet or exceed the nutrition requirement for broiler chickens. Chickens were fed ad-libitum experimental diets during the 42 days experiment period. On days 21 and 42, body weight and feed intake were measured to calculate the feed conversion ratio of the chickens. Intestine and visceral organs were measured together with meat quality and oxidative stability on days 14 and 42.
Chickens fed with EcoE showed improved (p<0.05) growth performance, meat quality, and higher (p<0.05) oxidative stability compared to the chicken fed on CON. Moreover, broiler chickens fed with EcoE showed similar (p<0.05) growth performance with better (p<0.05) meat quality and higher oxidative stability compared to the broiler chickens fed VitE (p<0.05).
The algae-based antioxidant containing Se yeast can be supplemented into commercial broiler diets as a substitution of VitE while maintaining growth performance with enhancing meat quality and oxidative stability of the broiler chickens.
进行一项实验，以确定含硒酵母的藻类抗氧化剂（EconomasE®）对肉鸡生长性能、内脏器官重量、肉质和氧化稳定性的影响。
960只1日龄雄性肉鸡（科宝品种，43.97±0.55克）被分为三种日粮处理组，并以完全随机设计分配到12个厚垫料鸡舍中，每个处理组有4个重复笼。三种日粮处理分别为：i）对照组（CON，营养充足的基础日粮），ii）维生素E组（VitE，基础日粮添加100国际单位维生素E），iii）含硒酵母的藻类抗氧化剂组（EcoE，基础日粮添加0.2%含硒酵母的藻类抗氧化剂：EconomasE®）。以玉米豆粕为基础配制日粮，以满足或超过肉鸡的营养需求。在42天的实验期内，鸡自由采食实验日粮。在第21天和第42天，测量体重和采食量，以计算鸡的饲料转化率。在第14天和第42天，测量肠道和内脏器官，并测定肉质和氧化稳定性。
与CON组鸡相比，EcoE组鸡的生长性能得到改善（p<0.05），肉质更好，氧化稳定性更高（p<0.05）。此外，与VitE组肉鸡相比，EcoE组肉鸡的生长性能相似（p<0.05），肉质更好（p<0.05），氧化稳定性更高（p<0.05）。
含硒酵母的藻类抗氧化剂可作为维生素E的替代品添加到商业肉鸡日粮中，在维持肉鸡生长性能的同时提高肉质和氧化稳定性。
