The objective of this study was to evaluate the reduction of protein, the formulation of diets and supplementation of an enzyme complex for laying hens. The layers were distributed in a completely randomized 2 × 2 × 2 factorial arrangement, with two levels of crude protein reduction (0.0 and 4.0 g/kg), two kinds of diet formulation (without and with reformulation, considering 75 kcal of metabolizable energy) and two enzyme supplementations (without and with enzyme complex supplementation), totalizing 8 treatments of 8 layers each, with 7 replications, in a total of 448 laying hens at 30 weeks of age. After data analysis, it was found that the enzyme complex supplementation in the diet of layers improves performance, promotes a similar egg quality and improves the bone and intestinal health of the layers.

Avaliaram-se as correlações entre a pluviometria e as características produtivas em caprinos Pardo-Alpina X Gurgueia criados em regime semi-intensivo no Cariri Ocidental, microrregião semiárida do estado da Paraíba. Utilizaram-se informações de peso ao nascer, produção de leite, mortalidade dos cabritos até os 90 dias de idade e pluviosidade registrada na Fazenda Carnaúba. Os dados pluviométricos foram transformados para LogX. Houve baixa correlação entre o peso ao nascer, a produção de leite e mortalidade com as variáveis pluviométricas.

The objective of this study was to evaluate the correlations between rainfall data and goat productive traits in Alpine X Gurgueia breeds goats, raised in a intensive regime in the Ocidental Cariri, a semi-arid microclime of Paraíba State, Brazil. Birth weight, milk production and mortality of kids to 90 days of age and rainfall data from the Carnauba Farm were used. The rainfall data were transformed in Log x. The birth weight, milk production and mortality correlated reasonably correlated with the rainfall variables. There was lower correlation among birth weight, milk production and mortality and the rainfall data.
