The effects of addition marolisTM probiotics for broiler performance and meat quality (Gallus gallus domesticus Linnaeus, 1758)

Marolis^TM is one of liquid probiotic product which commercially used in animal husbandry. Probiotics addition in diet of livestock such as poultry may increase productivity of poultry, improve its performance, immunity and reproductivity. This research was conducted to determine the effect of Marolis^TM probiotics on broiler performance and meat quality. Fourty DOC (Days Old Chiken) broilers were divided randomly into four groups. First group was control. Second group, third group and fourth group were treated with Marolis probiotic each different concentrations (0.5 mL, 1.0 mL and 1, 5 mL). Growth studies included measurements of body weight and morphometry, and meat quality was tested by measurements of water content using the Gravimetric method, measurement of ash content using the Gravimetric method, measurement of total fat using the Gravimetric method, and protein measurement using Kjeldahl method. The datas were obtained and statistically analyzed using IBM SPSS Statistics 20 by general linear model univariate test and compare means one-way Annova (a = 5). The results indicated that Marolis had significantly affected Broiler performance including increasing body weight, body length, wings length, tibia length and shank length. Marolis at a dose of 1.5 mL can improve the quality of broiler chicken meat, significantly increasing the percentage of total protein. It can be concluded that broiler which treatment by probiotic Marolis had improve the performance and meat quality of Broiler. © 2020 Elsevier B.V., All rights reserved.
