Effects of administration of multivitamins and enzymes for broilers either singly or in combination on body weight and haematobiochemical parameters

Abstract

The experiment was conducted on “Lohman Meat” broiler chicks to evaluate the effect of exogenous multivitamin and enzyme supplementation on body weight gain, haematological parameters (TEC, Hb content, PCV and ESR) and serum transaminases (AST and ALT). A total of 20, twenty days old broilers were randomly divided into four equal groups (5×4). Group A was considered as control, fed only with commercial ration, group B was treated at a dose rate of 0.5 ml multivitamins per 1 litre of drinking water, group C was treated at a dose rate of 1 ml enzyme per litre of drinking water and group D was treated with multivitamin @ 0.5 ml/L and Enzyme @ 1ml/ L in water from 1 to 21 days of experiment. It was observed that multivitamin and enzyme supplementation significantly (p<0.01) increased body weight. TEC, PCV and Hb content increased significantly (p<0.01) in the treated groups as compared to that of control group. ESR, AST and ALT values decreased significantly (p<0.01) in the treated groups. Therefore, it may be concluded that multivitamin and enzyme may be used with better performances in terms of increase of body weight and blood profiles.

Impact of Multienzymes Dose Supplemented Continuously or Intermittently in Drinking Water on Growth Performance, Nutrient Digestibility, and Blood Constituents of Broiler Chickens

“…This positive relationship between enzymes and immunity was recently reported [48,49]. Further evidence indicates a lack of adverse effects of enzymes on the markers for liver leakage and renal function, as enzyme supplementation in water significantly decreased AST and ALT, showing a decrease in liver leakage enzymes, showing an improvement in liver function [26][27][28][29].…”

“…The use of enzymes in feed to overcome the anti-nutritional factors, to increase feed utilization, and to improve performance as well as to decrease stress has received considerable attention [3,4,8,11,16,43]; so, also is the use of enzymes in water [26][27][28][29], with water application inducing superior performance [24]. This advantage may be due to faster distribution, application, and availability [24,25] and greater use of water as well [27]. However, the effect of the enzymes depends on diet composition (target substrate), the dose of the enzyme, and the age of chickens [5,9].…”

“…In addition, water supplementation of enzymes may lessen the harmful effects of aggressive heat exposure on enzyme activities when the pelleting temperature exceeds 85 • C and can replace expensive post-pelleting sparing systems [25]. Enzyme supplementation in drinking water significantly increased the body weight of broilers during different periods of growth, from 14 to 35 days of age, from 20 to 41 days, and from 20 to 40 days of age [26][27][28][29]. In addition, broilers that received multienzymes through drinking water recorded the highest weekly weight gain when compared to those given enzymes through the feed, and both groups had higher growth than unsupplemented controls [24].…”

“…However, contradictory results were found in the literature. Multienzyme supplementations at 0.5-1 mL/L water significantly decreased alanine aminotransaminase (ALT) and aspartate aminotransaminase (AST), showing an improvement in liver leakage markers [26][27][28][29]. On the other hand, plasma total protein was higher in enzyme supplemented-groups than of controls, but albumin, globulin and albumin/globulin ratio, ALT, and AST were not affected [13].…”

Assessment of the production performance and economic efficiencies of available chicken breeds (Gallus domesticus L.) in Rajshahi, Bangladesh

“…Moreover, Paul (2010) observed that multivitamin and enzyme supplementation significantly increased body weight in broiler chickens and the deficiency of vitamin C was related to meat yield reduction of broilers in a hot humid environment (Ali et al, 2010). Under intensive management system, on the other hand, chicken genotypes showed distinct physical variations for both qualitative and quantitative traits (Faruque et al, 2010).…”
