The intensification of production systems exposes animals to a series of stressful events, which makes it necessary to use products that increase the resistance of the organism. To reduce the use of synthetic products supplied to the animals, many studies with herbal medicines have been carried out, among them the fenugreek (Trigonella foenum graecum). The fenugreek is rich in polyphenols, flavonoids, phenolic acids, alkaloids and carotenoids, presenting positive results as immunostimulant, growth promoter and antioxidant effect. The objective of this work was to analyze the effect of the inclusion of increasing levels of fenugreek on the diet of Nile tilapia on immune parameters, performance and antioxidant activity in fillet. This is a pioneering work in Brazil. There were three treatments (0%, 1% and 2% inclusion of fenugreek) and four replications, in which tilapia juveniles were weighed and measured and later distributed randomly in polyethylene boxes in a recirculation system. They were fed for 45 days with the experimental diets. After the experimental period the biometry of all the animals was carried out, as well as the hematological, immunological, antioxidant activity and performance analyzes. The parameters of water quality were within the ideal for the species. The data were submitted to analysis of variance and when significant differences were identified were compared by the mean test (a = 0.05). There was no effect of the treatments on hematological, immunological parameters and antioxidant activity in fillet. However, performance was influenced (p <0.05) by treatments. Fish fed with 1% of fenugreek presented higher GP and CR, when compared to the control group. Animals supplemented with fenugreek presented better ICA when compared to control. The results indicate that the inclusion of fenugreek in the diet of Nile tilapia does not cause damage to the health of the fish and can be supplied as food additive for better results of zootechnical performance. More studies are needed to determine the optimal dose of inclusion as well as the time of administration. |
