Abstract
The aim of the present study was to compare the efficacy of commercial herbal products on performance and immune response of broiler. One hundred twenty chicks were randomly divided into 12 experimental units (replicates) having ten chicks each. These experimental units were allotted to four treatment groups (T1, T2, T3 and T4) such that each treatment has three replicates. Group T1 was without supplementation of any commercial herbal product and served as control while the birds in group T2, T3 and T4 were supplemented with commercial herbal products i.e. Livol, Livotal, and Hepato promoter @ 1 ml per 2 liter water, 1 ml per 4 liter water, 1 ml per 4 liter water respectively. Supplementation of different commercial herbal products by water during 2-5 weeks of age significantly (P<0.05), improved weight gain (6.36- 12.37%), consumed less feed (2.62-3.09%) improved feed conversion ratio (9.53-14.29%) and lowest mortality rate (3.33%). Supplementation of different commercial herbal products exhibited non-significant effect on dressed weight, relative weight of heart, liver, spleen, gizzard, pancreas and intestine of broiler. However, ND and IBD antibody titer was improved significantly (p<0.05) (T1). The birds using water supplemented with Hepatopromoter fetched the highest profit.
Highlights
Poultry meat is a very nutritive source of protein and other energetic nutrients that are long chain fatty acids, vitamin B complex, iron and zinc, which resulted in all over the world gradually acceptance of chicken meat and its products
The results proved that Supplementation of commercial herbal products in broilers significantly (p>0.05) improved the weight gain of the birds
V et al (2013); Sangoh and Park, (2012); Za n u et a l. ( 2 0 1 1 ) who reported that supplementation of neem, chicory, onion, garlic, ginger, anise and rosemary as a natural herbal growth promoters improved the weight gain of broilers [10,35,42]
Summary
Poultry meat is a very nutritive source of protein and other energetic nutrients that are long chain fatty acids, vitamin B complex, iron and zinc, which resulted in all over the world gradually acceptance of chicken meat and its products. Huge losses due to contamination of feed with pathogenic bacteria and their related effects in birds, such as poor weight gain or even increased mortality are major obstructions in its progress [34]. To overcome these problems antibiotic have been used in poultry for the past four decades to improve growth performance of poultry and to protect them from the antagonistic effects of pathogenic and non-pathogenic enteric microorganisms. The total use of antibiotics as a growth promoter is estimated to be 4500 tons per year Their usage in poultry industry is intensively controversial because the expansion of bacterial conflict and potential consequence on the human health [3,20,31]
