Abstract:

【Objective】 The aim of this experiment was to study the effects of different levels of Mytilaria laosensis leaves feeding on the growth performance, plasma biochemical indicators, jejunal mucosal cytokine content, hepatic detoxification and antioxidant indicators, carcass quality and meat quality of Yellow-feathered chickens. This study serves to evaluate the application value of Mytilaria laosensis leaves as a potential forest by-product feed ingredient for yellow-feathered chickens.【Method】 A total of 720 six-day-old fast-growing mahuang Yellow-feathered chickens with similar body weights were selected and randomly assigned to 6 treatment groups using a completely randomized design. The feeding levels of Mytilaria laosensis leaves were 0% (control group), 1.5%, 3.0%, 4.5%, 6.0% and 7.5%, and each group was set up with 6 replicates, with 20 chickens in each replicate (10 males and 10 females each), and the test period was 50 days. 【Result】 with the feeding levels of Mytilaria laosensis leaves increased, 1) During the period of 6 to 21 days of age, body weight, average daily gain, and eurobenefit index were increased quadratically (P<0.05), while feed conversion ratio and cost per kilogram gain decreased quadratically (P<0.05). From 22 to 42 days of age, both feed to gain ratio and weight gain cost were decreased linearly and quadratically (P<0.05). In the final phase of 43 to 55 days of age, body weight, average daily feed intake, feed to gain ratio, and weight gain cost were increased both linearly and quadratically (P<0.05), whereas the eurobenefit index was decreased in both linear and quadratic patterns (P<0.05). During the experiment of 6 to 55 days of age, the body weight, average daily gain, feed to gain ratio and weight gain cost of chickens were increased linearly and quadratically, while the eurobenefit index was decreased linearly and quadratically (P<0.05). 2) At 21 days of age, the plasma concents of TP, IgA, IgG, and the antibody titer against NDV-Ab were increased linearly (P<0.05). In contrast, the activities of ALT and CK, as well as the concentration of MDA were decreased both linearly and quadratically (P<0.05). At 55 days of age, compared with the control group, the TP concent was significantly higher in the 4.5% leaf group (P<0.05), while the TG concent was significantly lower in the 1.5% leaf group (P<0.05). 3) The feeding level of Mytilaria laosensis leaves had no significant influence on the organ indexes of chickens. 4) The contents of sIgA, TNF-α, IFN-γ, and IL-10 in jejunal mucosa were increased linearly and quadratically (P<0.05). No significant difference was observed in the concent of IL-1β in the jejunal mucosa (P>0.05). 5)The activity of CarE in liver was increased linearly and quadratically (P<0.05), while the activities of AchE and MDA content were decreased linearly and quadratically (P<0.05). No significant differences were observed in the activities of hepatic GSH-ST, T-AOC, and T-SOD (P>0.05). 6) The half-eviscerated rate of chickens was decreased linearly and quadratically (P<0.05), and the breast muscle rate was increased linearly and quadratically (P<0.05), and the abdominal fat rate was decreased linearly (P<0.05). 7) Compared with the control group, chickens in the 4.5% leaf group were demonstrated significantly higher redness (a*) values in the breast muscle at both 45 min and 24 h post-slaughter (P<0.05).【Conclusion】 In summary, the suitable of Mytilaria laosensis leaves can improve the growth performance, immune function, antioxidant and detoxification capacity, carcass quality and meat quality of yellow-feathered chickens. However, the feeding level of Mytilaria laosensis leaves requires precise control, as excessively high levels may adversely affect economic returns. According to quadratic regression model, combined with the body weight, average daily gain and feed to gain ratio as the main evaluation indicators, it is estimated that the appropriate feeding level of Mytilaria laosensis leaves for 6 to 55 days of age of fast-growing Yellow-feathered chickens is 2.75% to 2.90%. This study provided a scientific basis and experimental reference for the use of Mytilaria laosensis leaves as an unconventional feed ingredient in the rearing of yellow-feathered chickens.
