The effect of herbal feed additive on the growth performance, carcass characteristics and meat quality of broiler chickens fed low-energy diets

Abstract

The aim of this study was to determine the effect of herbal feed additive on growth performance, carcass characteristics, the chemical composition of breast muscles and selected meat quality parameters in broiler chickens. The experiment was performed on 1080 Ross 308 chickens, which were randomly divided into six groups with six replicates per group. In experimental groups, dietary energy concentration was reduced by 0.10 or 0.25 MJ kg-normal1, and the diets were or were not supplemented with the Superliv herbal formula at 500 g t-normal1 of diet. A statistical analysis revealed that Superliv had a beneficial influence on the final body weights (BWs) of birds, average daily gain (ADG), feed conversion ratio (FCR), European Efficiency Index (EEI) and the proportion of heart relative to total carcass weight. However, meat acidity measured 15 min post mortem was higher in experimental groups. A decrease in dietary energy concentration contributed to a highly significant increase in the water-holding capacity (WHC) of meat and natural drip loss, an increase in pH15, an increase in color lightness, a decrease in redness, an increase in the fat content of meat, and a decrease in malondialdehyde (MDA) concentration.

Effect of pomegranate (Punica granatum L) peel powder meal dietary supplementation on antioxidant status and quality of breast meat in broilers

“…The pH of meat is an essential factor that influences the colour, tenderness, cooking loss, shelf-life, and other physicochemical properties ( Shang et al., 2014 ). When meat pH rapidly declines, the tendency for it to be pale and have low water holding capacity increases ( Lipinski et al. 2019 ).…”

The Potential Impact of Moringa oleifera for Diminishing the Microbial Contamination and Prolonging the Quality and Shelf-Life of Chilled Meat

“…The active ingredients of phytogenic origin have gained interest due to their wide range of properties. The positive effects of plant extracts on animals, either on health status, productivity, or the quality of the derived products, has been widely studied 1,2 . Plant extracts have been used in poultry production for years.…”

The Effect of Different Probiotics on the Broiler’s Offals Percentage

“…The weight of internal organs such as the liver is commonly observed to see toxicity in a feeding experiment [7]. Feeds containing improper nutrition can cause liver morphological abnormalities including enlargement of its size [10]. Although giving different probiotics shows an effect on the percentage of liver and heart, the percentage of liver and heart of broiler is still in the normal range.…”
