Abstract

ObjectiveThe experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers.MethodsIn experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; D1 (control), D2 (D1 with 1 mL multivitamin/liter water), D3 (D1 with 1 mL acidifier/liter water), D4 (D1 with 1 mL multivitamin and 2 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication. In experiment 2, 150 day-old Cobb-500 broiler chicks were fed diets; T1 (control), T2 (5% Azolla in the diet), T3 (7% Azolla in the diet) and T4 (T1 with 1 mL multivitamin and 1 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication in control, and 10 chicks/replication in the remaining dietary treatment groups for 35 days.ResultsIn experiment 1, the highest live weight was observed in D4 (p<0.05), however, feed intake was statistically similar between diets (p>0.05). The lowest feed conversion ratio (FCR) (p<0.001) and mortality (p<0.05) were observed in D2 followed by D4, D1, and D3, respectively. There were no significant differences between diets for feed cost and net profit (p>0.05). However, evidently but not significantly, the highest net profit was obtained in D2 followed by D4, D1, and D3, respectively. In experiment 2, the highest live weight (p<0.05) and feed intake (p<0.001) were observed in T4. Mortality (p<0.01), FCR (p<0.01), feed cost (p<0.05) and net profit (p<0.05) were significantly different among diets. Considering net profit, T2 was the best performing dietary group followed by T3, T1, and T4, respectively. The lowest lipid profiles were observed in D3 followed by D1, D4, and D2, respectively (p<0.05). In experiment 2, the lowest total cholesterol, TG, and the highest amount of high density lipoprotein were observed in T2, followed by T3, T1, and T4, respectively (p<0.05). Evidently but not significantly, low density lipoprotein was the highest in T2 followed by T3, T4, and T1, respectively (p>0.05).ConclusionIn conclusion, Azolla and acidifier reduced lipid profiles of broiler chickens. Considering net profit and lipid profiles, 5% Azolla may be the suitable dietary group for producing safe and profitable broilers. However, more studies are needed to confirm this study prior to suggesting using Azolla in the poultry industry.

Highlights

Chickens are susceptible to vitamin deficiency because their gut flora can synthesize only a small amount of vitamins, and in intensive systems of rearing chickens undergoe many stresses [1]
Experiment 2 Growth performance of broiler fed diet with or without Azolla or blending multivitamin and acidifier at 35 days of age: The dietary groups; T1, T2 (5% Azolla in the diet), T3 (7% Azolla in the diet), and T4 (T1 with supplementation of 1 mL multivitamin and 1 mL acidifier/liter water) were significantly different in terms of live weight (p
No information has been found regarding the effect of blending multivitamin and acidifier on broiler chickens

Summary

Introduction

Chickens are susceptible to vitamin deficiency because their gut flora can synthesize only a small amount of vitamins, and in intensive systems of rearing chickens undergoe many stresses [1]. Farmers are randomly using unexpected growth promoters, antibiotics, hormones, enzymes, and protein concentrates containing heavy metals to produce rapid growth of chickens these additives may have a harmful effect on poultry as well as on humans. For these reasons, poultry scientists are trying to establish alternative poultry production using improved genotypes (e.g. naked neck), feeding, and access to an outdoor area to produce safe and profitable poultry production [2]. The present study was planned to assess the comparative effect of multivitamins, acidifiers and Azolla, either alone or combination, on growth performance, profitability and lipid profiles of broiler chickens for producing safe and cost effective broiler
