Effect of Labazyme on Growth Performance, Physiological Parameters, and Economic Efficiency of Broiler Chickens

Abstract

Enzymes have a significant positive effect on nutrient digestion, feed efficiency, and growth rate of poultry. The current experiment aimed to determine the optimal dosage levels of Labazyme as feed additives. A total of 240 one-day-old broiler chickens (Ross 308) were randomly assigned to four groups with three replicates. The feeding experiment was carried out from hatching to day 42 of age. Three experimental groups contained Labazyme at 0.5, 1, and 1.5 mg/kg of the total diet. The control group received a basal diet. Growth performance, European performance efficiency index (EPEI), production index (PI), biochemical and lipid profiles, as well as antioxidant parameters were then measured. The results showed that chickens fed Labazyme supplementation (1 and 1.5 mg/kg) had a higher growth performance than those in the control group. Nonetheless, there was a significant difference between the Labazyme and the control group in terms of feed intake. In addition, Labazyme groups had a significantly positive effect on broiler economic scores. The EPEI and PI of the Labazyme-fed chickens were both higher than the control. There was a non-significant difference in total protein, albumin, globulin, and uric acid. The serum glucose level of the chickens fed Labazyme (1 and 1.5 mg/kg) was lower, compared to the control group. In contrast, chickens that consumed a diet supplemented with Labazyme 1 and 1.5 mg/kg indicated lower serum cholesterol, triglyceride, low-density lipoprotein, and very-low-density lipoprotein levels in broilers, compared to the control group. Serum high-density lipoprotein levels were improved and more pronounced in chickens fed Labazyme, compared to the control group. In conclusion, the results of the current study indicated that supplementation of Labazyme could help the improvement of growth performance, lipid profile, and profitability of broiler chickens.

The impact of multi-enzyme fortification on growth performance, intestinal morphology, nutrient digestibility, and meat quality of broiler chickens fed a standard or low-density diet

“…The addition of multi-enzymes to the LDD significantly affected the total revenue, net revenue, and economic efficiency, showing positive influence. Our findings are in line with those of Abdulwahid et al ( 49 ), who studied the economic impact of Labazyme as a feed additive in broiler chickens and observed that feed cost was significantly higher in the experimental group than in the control group. The economic evaluation, production efficiency, and production index were highly significant in broiler chickens fed a Labazyme supplement compared with the control.…”

Growth Rate of Broiler Production Affected by Xylo-Oligosaccharides and Chitosan

“…T 3 : 1 g/kg Xylo-oligosaccharides, and T 4 : mixed (0.5+0.5 g/kg Chitosan and Xylo-oligosaccharides) In the table (3) the results showed there were no significant differences were recorded for the second, third, fifth, and sixth weeks between chitosan and Xylo-oligosaccharides treatments compared to the control treatment, either for the fourth week there was a significant increase for bird treated with Xylooligosaccharides (T 3 ) compared to T 2 and T 4 and control treatment. However, the results in table (4) showed there was significant difference between the treatments and control in FCR, we found the supplement with chitosan and Xylo-oligosaccharides was significant compared to the control (T 1 ).…”

“…Through advancements in nutritional science, proper management, and improved genetic over the past 50 years, the poultry industry has made significant advances in its production system [1], feed additives and dietary supplements are becoming increasingly important in today's poultry industry and healthcare systems [2], and had beneficial effects including promoting growth and production, boosting the immune system and protecting health [3,4]. Chitosan is a non-toxic polyglucosamine that is, to varying degrees, deacetylated from chitin, a substance found in the exoskeletons of insects, shrimp, and crabs [5,6].…”
