Effect of Lacquer (Rhus verniciflua) Supplementation on Growth Performance, Nutrient Digestibility, Carcass Traits and Serum Profile of Broiler Chickens

Abstract

This experiment was conducted to explore the efficacy of lacquer (Rhus verniciflua) supplementation on growth performance, nutrient digestibility, carcass traits and serum biochemical values in commercial broilers. Eight hundred and forty Hubbard broiler chicks (1d old) were randomly distributed and allotted to four dietary treatments for five weeks. Each treatment had 5 replicates with 42 birds each. The dietary treatments were (1) control (2) 1% lacquer, (3) 2% lacquer and 4) 4% lacquer supplied as meal in the diet. Supplementation with lacquer improved weight gain (p = 0.0960) showing a linear trend during the starter phase (0-3 wk), but weight gain, feed intake and feed conversion ratio remained unaffected at the finisher phase (4-5 wk) and overall (0-5 wk). The nutrient digestibility studies conducted after 18 and 35 days of experimental feeding showed a linear (p<0.05) increase in digestibility of CP and ether extract at both measurement timess. The carcass studies were conducted on two birds per replicate (10 per treatment) at the end of both 3 and 5 wk. The dressing percentage, liver weight, heart weight, abdominal fat and the breast meat expressed as a percentage of live weight, did not differ significantly due to treatments at both phases. The serum cholesterol and high-density lipoprotein (HDL) showed a linear decrease (p = 0.0683 and p = 0.0322, respectively) as the level of supplementation increased at 3 wk; at 5 wk serum cholesterol, HDL and triglyceride levels decreased significantly showing a positive linear effect of lacquer on fat metabolism. The meat color values such as lightness, redness and yellowness did not reveal any significant trend. Overall, it could be concluded that lacquer supplementation at higher levels did not affect growth performance, but had a positive impact on fat metabolism by influencing fat digestibility and reducing serum cholesterol and triglyceride.

Effect of Inclusion of Lacquer (Rhus verniciflua Stokes) Meal on Carcass Traits and Meat Quality in Growing-finishing Pigs

“…The experimental diets were made isoenergetic by replacing parts of maize by animal fat in diets incorporated with lacquer meal and thus the ether extract was higher in these diets than control diets. Similar to the findings of the current study, no growth performance benefits were reported in broilers (Lohakare et al, 2006) and finisher pigs when their diets were supplemented with lacquer meal at 20 and 40 g/kg diet.…”

“…In broilers, inclusion of lacquer meal did not have any effect on growth performance, but improved fat digestibility and reduced serum levels of cholesterol and triglyceride (Lohakare et al, 2006). In our previous study, lacquer meal added to the finisher diets of pigs at 20 and 40 g/kg reduced back fat and improved oxidative stability of meat but there was no effect on the growth performance and carcass traits .…”

“…Nurhayati et al (2005) reported that chickens were offered 0, 2.5, 5.0, 7.5 and 10% of pace meal had similar (P>0.05) feed consumption and pace meal did not significantly (P>0.05) increase feed consumption. Lohakare et al (2006) reported that lacquer is usually used as traditional medicine by Japanese, Chinese and Korean. There was no different effect among 0, 1, 2 and 4% of lacquer meal on increasing broiler feed consumption.…”
