The objective of this study was to evaluate the use of an enzyme complex-α-amylase, ß-glucanase, phytase, cellulase, xylanase and protease-in the feed of swine in growing and finishing phases, by assessing their performance (daily weight gain, daily feed intake, and feed conversion), dry matter, crude protein, and crude energy apparent digestibility, and the feed costs. Eighty pigs-castrated males, and females-of approximately 63 days of age and initial weight of 20.18±1.98 kg were distributed in a 5×2 factorial arrangement (diet × sex), in a randomized block design, with eight replications. The treatments used were: positive control diet consisted of 3,300 kcal/kg in the growth-I phase, and 3,250 kcal/kg in the growth-II and finishing phases; negative control diet with energy reduction of 85 kcal/kg of metabolizable energy (ME) (NC85); NC85 diet with addition of enzyme complex (EC85); negative control diet with energy reduction of 100 kcal/kg ME (NC100); NC100 diet with addition of enzyme complex (EC100). The addition of the enzyme complex to the diet with energy reduction of 100 kcal/kg ME increased the digestible protein content of the diet for the swine in the growth-II phase. The addition of the enzyme complex to the diet with energy reduction of 85 and 100 kcal/kg ME increased the digestible energy content of the diets for the swine in the finishing phase. The use of enzyme complex in diets with reduction of 85 kcal/kg ME for male swine in growing and finishing phases is recommended for improving feed conversion and economic efficiency during the growth-I phase. The use of enzyme complex is not justified for female swine.

Objetivou-se determinar a interferência do aditivo extrato de Yucca schidigera em diferentes concentrações e fontes comerciais (EYA vs EYB) nas características fecais de cães. Utilizaram-se 15 cães adultos da raça Beagle, distribuídos em delineamento em blocos ao acaso, totalizando 6 repetições por tratamento. Foram analisadas nas fezes a matéria seca fecal (MSf), produção fecal, amônia, escore, pH e odor fecal. Houve diferença nos valores de MSf, produção fecal e para odor fecal em ambos os testes realizados (P<0,05). A concentração de 0,07% de EYA resultou em maior MSf e menor odor fecal em relação ao EYB.

A kind of the consumption forms of drinks presentation that has grown and appreciated for the most people is the nectar. The papaya nectar had recognized as a differentiated form of this fruit, where the industry also gains in time of conservation, since the papaya is an extremely perishable fruit. The aim of this study was to evaluate gamma radiation as a way of conserving papaya nectar. Papaya nectar was developed and subjected to gamma radiation at the dose of 1kGy in a dose tax of 0.356 kGy.hour-1 and compared this treatment with the control (0kGy). According to the results obtained, can be concluded that the dose used was adequate for the conservation of this product for the period evaluated reaching the aim.
