| Foram avaliados os efeitos da aplicação de Impact P® sobre a cama de aviário de matrizes de corte mediante o monitoramento de parâmetros microbiológicos. O Impact P® é um produto formulado através de Bacillus subtillis e suas enzimas que atuam sobre os dejetos animais e matéria orgânica, utilizando-os como fonte alimentar, visando melhorar as condições da cama dentro de aviários. Na 58ª semana de idade das matrizes foi trocado todo material de cama e então aplicados os seguintes tratamentos: T1- controle; T2 - Impact P® na dosagem de 2,5gm-2 de cama; T3 - Impact P® na dosagem de 5,0g m-2 de cama. Foram realizadas contagens de enterobactérias totais em agar McConkey em amostra de cama nova e após 3, 10, 17, 24 e 31 dias de uso da cama pelas aves e... |

| Os objetivos neste experimento foram avaliar o efeito do tempo de exposição a um progestágeno (P4) na taxa de prenhez de novilhas púberes e pré-púberes inseminadas em tempo-fixo (IATF) e estudar o retorno econômico dos protocolos utilizados, por meio da comparação desses protocolos ao sistema tradicional de acasalamento natural aos 26 meses de idade. Foram utilizadas 114 novilhas da raça Bradford com 16 meses de idade, classificadas em quatro grupos de acordo com o tratamento e a maturidade sexual: GPPLP - pré-puberes, longo tratamento com P4 (n=21); e GPPCP - pré-puberes, curto tratamento com (n=19); GPLP - púberes, longo tratamento com P4 (n=34); e GPCP - púberes, curto tratamento com P4 (n=40). As novilhas do GPPLP e GPLP receberam no dia -8 um pessário... |

| The influences of floor- and cage-rearing on egg production, egg quality and physical condition were investigated in laying hens housed in furnished cages. Two groups of 180 Isa Brown commercial layer pullets were reared in cages (CR) or floor pens (FR) and transferred to furnished cages, where their production, egg quality and physical condition was observed throughout the laying period (18-78wks of age). At 17 weeks of age, hens were placed in one of 36 furnished cages with 10 birds in each cage, each containing a nest box, perches, a dust bath, and abrasive strips. From 19 to 78 weeks of age, egg production data were collected daily. Commercial egg quality was assessed monthly. At, 19 and 78 weeks of age, claw length and feather cover were visually... |

| The aim of this study was to evaluate the metabolic profile of the use of soyabean hulls associated with two sources of non-protein nitrogen (NPN) on the finishing of feedlot lambs. Eighty crossbred Suffolk non-castrated lambs aging 69±6 days and weighing 23.11±1.78 kg were used. Lambs were randomly allocated into 4 experimental groups according to the NPN source: conventional urea (1%); protected urea; 1% protected urea + 0.5% conventional urea; and a control group, which did not receive urea supplementation. Blood samples were collected weekly to determine the plasma concentrations of urea, albumine, γ-glutamiltransferase (GGT), calcium and phosphorus. The control group had higher average daily gain and final weight than protected urea and protected urea... |

| ABSTRACT: In order to evaluate the efficiency of phytase in diets with low and high phytate phosphorus (PP) 0content, as a consequence of wheat bran inclusion, on the relative weight of organs, intestinal morphometry and performance, three hundred and eighty-four male Cobb500 broilers were housed in metabolic cages. Animals were assigned into four treatments in a 2x2 factorial scheme in a randomized block design with eight replicates of 12 birds each. From 11 days of age birds received experimental diets, which consisted of: Diet low in PP; Diet low in PP with phytase (500FTU kg-1); Diet with a high PP and Diet with a high PP with phytase (500FTU kg-1). At 22 and 32 days of age two birds were slaughtered in order to collect gizzard, heart, liver, cecum,... |

| The influences of floor and cage-rearing on behavioural adaptation to furnished cages were investigated in laying hens. Two groups of 180 Isa Brown commercial layer pullets were reared in cages (CR) or floor pens (FR) and transferred to furnished cages, where their behavioural adaptation was observed throughout the laying period (18-78 wks of age). At 17 weeks of age, hens were placed in one of the 36 furnished cages with 10 birds in each cage, each containing a nest box, perches, a dust bath, and abrasive strips. At 50 and 54 weeks of age, direct visual observation and video recording were used to assess hens behaviour. From 21 weeks of age, the dust-bath activities of leg-banded hens in eight cages per treatment were recorded. The amount of time spent... |
