The use of tanniferous plant in the goat diet as alternative to parasite control

O presente trabalho avaliou a eficácia da torta de pimenta rosa (TPR) na dieta de caprinos leiteiros nas fases de cria e recria, como agente antiparasitário frente ao controle da coccidiose com ionóforo, monensina sódica. Foram utilizadas 18 cabras, da raça Saanen, distribuídos em delineamento inteiramente casualizado em grupos de três tratamentos e seis repetições, constituídos pelos grupos experimentais: grupo 1 - controle sem adição de ionóforo ou de TPR; grupo 2 - suplementado com 30% de TPR; grupo 3 - controle positivo adição de monensina sódica. Observou-se efeito significativo dos tratamentos sobre o consumo voluntário animal, tanto na fase de cria quanto na de recria, sendo que os animais suplementados com TPR tiveram os menores valores de consumo comparado com os demais grupos (P?0,05), mas sem interferir negativamente no peso corporal. Em geral, tanto na fase de cria quanto de recria, o consumo voluntário entre os grupos controle negativo e controle positivo, não diferiram entre si (P>0,05). Na fase de recria constatou-se que houve efeito dos tratamentos sobre o peso corporal (P?0,05), a partir da sétima semana de experimento. Os animais alimentados com TPR tiveram um peso corporal superior ao controle negativo (P?0,05) e similar aos tratados com a monensina sódica (P>0,05). A contagem de oocistos por grama de fezes foi menor nos animais tratados com TPR diferindo significativamente do controle negativo (P?0,05). Em relação à contagem de ovos por grama de fezes não houve efeito significativo dos tratamentos (P>0,05). Verificou-se que o TPR foi eficaz no controle dos protozoários da família Eimeriidae, com potencial para serem utilizadas em programas alternativos de controle da eimeriose caprina. Concomitantemente, também maximizou o desempenho animal conferindo maior peso corporal mesmo com a redução de consumo voluntário.This study evaluated the effectiveness of pink pepper meal supplementation (PPM) in the dairy goats diet as an antiparasitic agent compared with ionophore, the monensin sodium. A total of 18 female Saanen goats, were distributed in a completely randomized in groups of three treatments and six replications, consisting of the experimental groups: negative control (did not receive anticoccidial agent or PPS), group 1 (supplemented with 30% of PPM) and group 2 (supplemented with anticoccidial agent – monensin sodium). There was a significant effect of treatments on voluntary feed intake on growing phases (P ? 0.05). Furthermore, the animals treated with PPM had the lowest food consumption compared with the other treatments (P ? 0.05), but without negative effect on live body weight. In general, at both phases of rearing, it was not detected significant difference between the voluntary feed intake of control group and with monensin sodium supplementation (P > 0.05), but the food consumption in the control group did not result on increase of live body weight probably due to sanitary challenges such as gastrointestinal parasites. The opposite was observed in animals treated with monensin sodium that had the highest body weight (P ? 0.05) that did not differ from animals fed with pink pepper (P > 0.05). By the way, in the growth phase our results revealed significantly effect of treatments on live body weight (P ? 0.05). Animals fed with pink pepper supplementation had a greater live body weight compared with the control (P ? 0.05) and similar to those supplemented with the monensin sodium (P > 0.05). The number of oocysts per gram of faeces was lower in animals treated with PPS that differed significantly from control (P ? 0.05). Regarding the count number of eggs per gram of faeces OPG, it was not detected significant effect of treatments (P> 0.05). It was found that the pink pepper supplementation was effective in the control of gastrointestinal parasites of goats, mainly on protozoa family Eimeriidae, revealing potential for use in alternative parasite control programs. Concomitantly also it was showed maximizing animal performance by high live body weight even with the reduction of voluntary feed intake
