Extrato vegetal de noni (Morinda citrifolia) como promotor de crescimento para frangos de corte

Abstract

In this study were evaluated the use levels of Noni extract (Morinda citrifolia) on intestinal histomorphometry, nutritional metabolism, biochemical serum profile, and performance of broilers. Completely randomized design with six treatments and six replicates of ten male commercial Cobb chicks were used in each replicate. The broilers was spraid treatments with addition to the diet of 150, 300, 450, and 600 ppm of noni extract, beyond negative and positive controls, without or with 25 ppm of tylosin, respectively. Feed intake, weight gain, feed conversion of broilers at 7, 21, and 35 days old were evaluated at the performance test. The nutrient metabolization was determined using the method of total excreta collection. At 7, 21, and 35 days old, the two birds per replicate was collected, after blood collection, the birds were euthanized to histomorphometry of the intestinal segments. Data were subjected to regression analysis, considering linear and quadratic models for variance analysis. Subsequently, treatments with Noni levels were compared with the negative and positive controls, using the F test for orthogonal contrasts. The inclusion of noni in the diet of plant extracts does not change the performance, carcass characteristics, biometrics of the digestive system, intestinal histomorphometry, and biochemical serum profile of broilers, in relation to diet without growth promoter. Therefore, although it is not hepatotoxic, noni extract did not improve growth in broilers.

Modulation of Gut Microbiota, and Morphometry, Blood Profiles and performance of Broiler Chickens Supplemented with Piper aduncum, Morinda citrifolia, and Artocarpus altilis leaves Ethanolic Extracts

“…Studies have been performed in chickens, where extracts from different plants, such as Indian frankincense, caraway ( Carum carvi L.), cloves ( Syzygium aromaticum ), holy basil ( Ocimum sanctum ), and licorice have shown improved productive indices ( 15 , 16 , 88–90 ). Nonetheless, the results from the present study also contrast with those of previous studies, in which the productive performance indices of chickens did not vary on using of M. citrifolia leaf powder or different fruit extract concentrations ( 33 , 63 ). On the other hand, this EE did not influence the daily feed consumption and carcass yield ( p > 0.05), which are in line with previous studies where have been shown that the inclusion of plant extracts or essential oils as feed additives may positively or negatively influence the organoleptic characteristics of the diet such as aroma and taste ( 103 , 104 ).…”

“…Nonetheless, in previous studies in rats, triglyceride levels were unaffected after treatment with P. aduncum essential oil, like the results obtained for glucose, AST, and ALT levels ( 53 , 62 ). A similar study has shown that the use of M. citrifolia fruit extract at different doses does not alter the triglyceride, AST, or ALT levels in chickens ( 63 ).…”
