Torta de dendê em dieta para a tilápia-do-nilo: Desempenho produtivo

To evaluate the nutritional value of African palm kernel meal (Elaeis guineensis) on the performance of Nile tilapia (Oseochromis niloticus), five isonitrogenous (30% crude protein), isoenergetic (2,800 Kcal/kg of digestible energy), and isofibrous (10% crude fiber) diets, with increasing levels of African palm kernel meal (0, 7, 14, 21, 28 and 35%) were fed ad libitum for 18 weeks to Nile tilapia (Oreochromis niloticus) fingerlings, averaging 1.52 ± 0.04 g of body weight, housed for 120 days in 60 liter aquaria with six fingerlings. To determine the production traits, weight gain, apparent food conversion, specific growth rate, protein efficiency ratio, weight gain percentage, net protein utilization, and body composition, fish were weighted at six-week intervals. Statistical analysis of recorded data were performed through multivariate profile analysis and polynomial regression models. Results showed that feeding fingerling Nile tilapia with ratios containing up to 35% of African palm kernel meal does not affect production performance.

Efeitos da restrição alimentar no desempenho de bovinos jovens confinados

The objective of the study was to evaluate compensatory weight gain in the performance of young bulls submitted to feed restriction, in the initial phase of confinement and to study the economic viability of the utilization of three protein sources. Sixty six crossbred bulls Simental-Nelore, eight months old and averaging 220 kg of weight were submitted to three feeding programs in the growth phase that lasted 84 days. The feeding programs were ad libitum, restriction + raw soybean grains and restriction + toasted soybean grains, with a restriction level of 25% on average. In the finishing phase, with a 61 day duration, animals fed with each of the three diets mentioned above received two types of supplementary diets: raw soybean grains and poultry litter. There were no differences between final weights of animals in finishing phase, but the bulls submitted to the restriction had more weight gain per day and better food conversion than ad libitum animals, for both raw soybean grains and poultry litter. The conclusion was that the feeding restriction and consequent compensatory weight gain, presented advantages for feeding efficiency, by decreasing maintenance requirements, although final cost had been equivalent to ad libitum animals.

Caracterização e análise do estado mental e funcional de idosos institucionalizados em instituições públicas de longa permanência

Background: This study had as objective to characterize the institutionalized elderly residents in three long-term care facilities, about their functional capacity and mental state, and to evaluate if there is a correlation between both. Methods: To do so, three instruments were used: an identification form, the Mini-Mental State Examination (MMSE) and Barthel's Index. For statistical analysis the Person's Correlation and ANOVA Test were used. Results: The population studied consisted of 115 elders with ages between 62 and 104 years old, 40.66% females and 59.13% males. 49.56% are literate and 50.43% illiterate. Regarding the marital status, singles (46.65%) and widows (21.8%) were predominant. About the mental and functional state, there was a high rate of elders showing cognitive decline (76.72%) and functionally independent (75.65%). Conclusions: According to the results, one can notice that there is a mild degree of correlation between the Barthel's Index and MMSE (r = 0.441; p < 0.000), and the variables of gender and age are not influenced in the results of these instruments. There is a significant statistical relation (p < 0.0001) between education and mental and/or functional state of the individual.

Desempenho e características de carcaça de cordeiros alimentados com fontes de carboidratos associadas ao óleo de girassol

This work was carried out with the objective to evaluate the effect of different carbohydrate sources associated with sunflower oil on performance, carcass characteristics and cuts yields of feedlot sheep. Twenty four lambs were assigned to a completely randomized design with a 2 × 2 factorial arrangement with two sources of neutral detergent soluble carbohydrate, starch or neutral detergent soluble fiber, with and without the inclusion of 4.2% sunflower oil. The treatments consisted of diets containing high content of soluble fiber (17.14% DM) without adding oil, high in soluble fiber (16.35% DM) with inclusion of 4.2% sunflower oil, high starch (30.14% DM) without adding oil and high starch (28.21% DM) with addition of 4.2% of sunflower oil. The animals were feedlot with average initial of 17.7 kg and when reached 35 kg body weight were slaughtered. The different sources of carbohydrate and oil inclusion in the diet not influence the days on feedlot in the dry matter intake and average daily weight gain, but higher feed conversion was observed for the diet with a high percentage of neutral detergent soluble fiber compared to diet high in starch. The carcass weights and yields as well as the commercial cuts were not affected by diets. The performance and quantitative characteristics and carcass cuts of lamb are not affected by different carbohydrate sources and their association with 4.2% sunflower oil.
