| ABSTRACT We evaluated the effects of a protease supplementation on the growth performance and intestinal health of broilers. Cobb chicks (392; 1-42 d) were divided into four treatments (seven replicates of 14 birds each). There were two feed formulations: a standard diet (SD) and a low crude protein and digestible amino acids diet (Low CP&AA). The two diets were either supplemented (+P) or not (−P) with a protease (Jefo Protease; 1.25 g kg−1). Performance was evaluated by feeding phases (1-7, 8-21, 21-35, and 35-42 d). On day 28, ileum samples were analyzed by a morphometric index for histological alterations (I See Inside Scoring System – ISI). Broilers fed the Low CP&AA had a poor feed conversion ratio (FCR); however, the addition of the protease... |

| The relationship between the quality of dietary crude protein and health of bullfrog juveniles (Lithobates catesbeianus) was evaluated by necropsy and histopathological examination of animals. The histopathology results showed that animals fed different feeds, regardless of CP levels, presented lymphocytary hepatitis, colitis and flattened microvillosities; kidneys with areas of tubulonephrosis and renal tubule calcification; myocarditis and cardiac muscular fiber dissociation. Such injuries suggested a degenerative nutritional process, with development of inflammatory processes spread to all the organs. These findings suggested that the animals had been fed with proteins of low biological value, indicating, apparently, poor feed quality, that harmed the... |

| ABSTRACT In the present study, we aimed to assess the toxicity of artemisinin on the haematological system and its effect on the productive performance of broiler chickens. Eighteen-day-old chickens were randomly divided into four groups of 30 chickens (three replicates of 10 broilers/group): control group and three experimental groups: ART5 - diet with 5 ppm of artemisinin; ART50 - diet with 50 ppm of artemisinin; and ART500 - diet with 500 ppm of artemisinin. Artemisinin enhanced the productive performances of broiler chickens at the lowest concentration (5 ppm), but at the highest concentration (500 ppm), it negatively affected weight gain and the feed conversion ratio. The performance characteristics of the chickens whose diets were supplemented with... |

| In order to complement the histopathological study of juveniles and tadpoles of the bullfrog, Lithobathes catesbeianus, fed commercial diet used by frog farms in Rio de Janeiro, containing 40% crude protein, we performed necropsy and histopathology of the liver to establish a relationship between the quality of crude protein in the diet and animal health. For this, it was used twenty breeding male bullfrogs, with average weight 591.30 g (± 91.90 g) and length 165.02 mm (± 14.22 mm), and ten females with average weight and length of 629.80 g (± 134.47 g) and 169.32 mm (± 21.82 mm). The liver histopathology showed hyperemia, high number of melanomacrophages and cytoplasmic rarefaction, probably due to protein deficiency and fatty liver degeneration and... |

| Para tornar a pecuária leiteira rondoniense mais competitiva em relação aos demais estados brasi-leiros, a adoção de tecnologias é fundamental para a intensificação do processo de produção. Esse processo de intensificação visando à redução de área e/ou aumento da produção por área e maxi-mização dos lucros depende, estritamente, do manejo adotado para a alimentação do rebanho, já que os custos com a alimentação representam em torno de 40% a 60% do custo total de produção. Logo, o planejamento adequado do manejo nutricional do rebanho evita gastos desnecessários e favorece a lucratividade da atividade. O planejamento alimentar, no entanto, depende de conheci-mentos sobre o potencial nutricional dos alimentos disponíveis para a alimentação do rebanho, das... |
