Abstract

A study was conducted to evaluate the effect of Piper nigrum (black pepper) leaf extract on on the growth performance, proximate composition, hematological parameters, and immune response of Labeo rohita fingerlings with an average weight of 22.14 ± 0.98g. Aftrer acclimation for two weeks, fish (n=25) were randomly selected and placed in four glass aquaria (T0, T1, T2 and T3) at constant water temperature (30.0 ± 1.0 °C), pH (7.50 ± 0.5) and total hardness (200 ± 2.0 mgL,-1) for a period of 12 weeks, with three replicates each. Fish were fed with P. nigrum leaf extract supplemented feed @ 0.0%, 1.0%, 2.0% and 3.0% in T0, T1, T2 and T3, respectively. At the end of experiment, five fish were randomly selected from each aquaria for proximate composition, gut and skin microbial load, hematological parameters. Total proteins, albumins, and globulins were also recorded to evaluate immunological memory. The result revealed that fish in T2 showed better growth performance with an average weight gain of 56.11 ± 0.51 g. Thus, it had been concluded that Piper nigrum, a medicinal plant, can also be used to enhance the growth performance and immune response of Labeo rohita as attractive alternatives against antibiotics and vaccines and has shown no negative side effects on fish health as well as on its environment.

Um estudo foi conduzido para avaliar o efeito do extrato da folha de Piper nigrum (pimenta-do-reino) sobre o desempenho de crescimento, composiçâo centesimal, parâmetros hematológicos e resposta imune de alevinos de Labeo rohita com peso médio de 22,14 ± 0,98g. Após aclimataçâo por duas semanas, os peixes (n = 25) foram selecionados aleatoriamente e colocados em quatro aquários de vidro (T0, T1, T2 e T3) em temperatura constante da água (30,0 ± 1,0 °C), pH (7,50 ± 0,5) e dureza total (200 ± 2,0 mgL-1) por um período de 12 semanas, com trés repetiçoes cada. Os peixes foram alimentados com raçâo suplementada com extrato de folha de P. nigrum @ 0,0%, 1,0%, 2,0% e 3,0% em T0, T1, T2 e T3, respectivamente. Ao final do experimento, cinco peixes foram selecionados aleatoriamente de cada aquário para composiçâo centesimal, carga microbiana intestinal e cutánea e parámetros hematológicos. Proteínas totais, albuminas e globulinas também foram registradas para avaliar a memória imunológica. O resultado revelou que os peixes em T2 apresentaram melhor desempenho de crescimento com ganho de peso médio de 56,11 ± 0,51 g. Assim, concluiu-se que Piper nigrum, uma planta medicinal, também pode ser usado para melhorar o desempenho de crescimento e resposta imunológica de Labeo rohita como alternativas atraentes contra antibióticos e vacinas e nâo mostrou efeitos colaterais negativos na saúde dos peixes, bem como sobre seu ambiente.
