Abstract
The aim of this study was to evaluate the efficacy of different levels of peppermint (Mentha piperita) on broiler performance, jejunum morphology, organs percentage and serum biochemical content. A total of 576-day old ross 308 chickens was divided randomly into 12 treatments with 4 replicates pen per treatment and 12 birds each pen. Treatments were arranged in a 2 × 6 factorial arrangement of treatments was employed. Factors were challenge, - or +; control, antibiotic, 0.5 % peppermint in feed, 1% peppermint in feed, 0.5% peppermint in water and 1% peppermint in water. The result of study was showed that the peppermint supplementation was significant effect on feed intake, feed conversion ratio and it has effect on body weight at day 24 and 35. The peppermint supplementation either in feed and water at 24 day had a significant effect on jejunum muscle thickness and villus/ crypt ratio while not effect on villus height and crypt depth. In conclusion, supplementation of peppermint has positive effect on broiler performance and gut morphology.
Highlights
Commercial poultry egg and meat production dramatically increased all over the world between 1970 and 2005, poultry production was increased faster than other animal production like beef [26]
Some studies indicated that essential oils of peppermint inhibit the growth of Escherichia coli, Staphylococcus aureus, Salmonella enteritidis, and Candida albicans [22]
This study aimed to determine the effect of different levels of peppermint (Mentha piperita) in feed and water on broiler performance at 10,24,35 day and histology of jejunum and organs percentage and serum biochemical at day 24
Summary
Commercial poultry egg and meat production dramatically increased all over the world between 1970 and 2005, poultry production was increased faster than other animal production like beef [26]. Escherichia coli belongs to the enterobacteriacea family, gram-negative bacteria, growing aerobic and anaerobic with varying size and shape [20] They mainly affect intestine of birds which cause many diverse diseases, in which Escherichia coli (APEC) is the main reason of colibacillosis in broiler chickens [15]. It has a negative economic impact on poultry production worldwide. This study aimed to determine the effect of different levels of peppermint (Mentha piperita) in feed and water on broiler performance (weight gain, feed intake, FCR) at 10,24,35 day and histology of jejunum (villus height, crypt depth, villi/crypt ratio, muscle thickness) and organs percentage and serum biochemical at day 24. ML) at 8 and 9 day of the bird’s age
