Desempenho de novilhos de corte em pastos de capim-tanzânia sob quatro alturas de desfolha

This study was carried out to evaluate the effects of four grazing heights under continuous stocking of Tanzânia grass (Panicum maximum Jacq. Cv. Tanzânia) on the stocking rate, performance and beef production per hectare. The experimental area was 12 hectares, divided into paddocks with one hectare each, with three replicates each (20, 40, 60 and 80 cm). There were three male Nellore bovines per paddock, adding animals as needed to adjust the desired heights in a completely randomized design. The stocking rate had a negative linear function of grazing heights in all seasons regarding yield per hectare, while the average daily gain showed opposite behavior. Apparently, Tanzânia grass heights between 40 and 60cm under continuous stocking enable good average daily weight gain in beef cattle, and high yield per hectare.

Sobrepeso pré-gestacional associa-se a ganho ponderal excessivo na gestação

PURPOSE: To evaluate the adequacy of gestational weight gain and to determine its association with maternal socioeconomic, demographic and nutritional factors and health care, to estimate the prevalence of low birth weight, macrosomia, preterm birth and cesarean delivery and to identify the association of these outcomes with the adequacy of weight gain. METHODS: A cross-sectional study was performed in 2009/2010 to obtain socioeconomic, demographic, nutritional, dietary and physical activity data of pregnant women assisted by primary health care in a municipality of the state of São Paulo. Subsequently, data were collected from the medical records to evaluate gestational weight gain. Type of delivery, birth weight and gestational age at delivery were obtained from the Livebirths Information System. Gestational weight gain was evaluated according to the recommendations of the Institute of Medicine (2009). Associations were investigated by comparing the frequencies and by logistic regression, with excessive weight gain (yes, no) and insufficient gain (yes, no) being the dependent variables. RESULTS: A total of 212 pregnant women were studied: 50.5% had excessive gain and 19.8% insufficient weight gain. Only prepregnancy nutritional status was associated with adequacy of weight gain: compared with normal weight, prepregnancy overweight women had a four-fold higher chance to gain excessive weight (OR 4.66, 95%CI 2.19-9.4). Nearly a third of babies were born by caesarian section, 5.7% were premature, 7.1% were underweight and 4.7% were macrosomic. There was no association between adequacy of gestational weight gain and these outcomes. CONCLUSION: The proportion of inadequate gestational weight gain was high. Overweight pregnant women have a four-fold higher chance to gain excessive weight, and priority should be given to actions promoting adequate prenatal weight gain.

Relative bioavailability of iron from organic sources for weanling piglets

Some authors consider minerals from organic sources more bioavailable for pig nutrition in comparison with inorganic sources. To evaluate the relative iron bioavailability from the organic source iron carbo-amino-phospho-chelate (ICAPC) to weanling piglets, it was conducted an experiment with 126 commercial piglets, using iron sulfate monohydrate (S) as standard. The experiment had a randomized block design with seven treatments (diet without adding specific source of iron, diet with 50, 100 and 150 ppm iron from S and diet with 50, 100 and 150 ppm iron from ICAPC), six replications and three animals per experimental unit. Performance parameters (average daily gain - ADG, feed: gain ratio - F:G) and blood variables (hemoglobin - Hb, hematocrit - Ht, transferrin - TR, latent iron-binding capacity - LIBC, total iron-binding capacity - TIBC, serum iron - Fe and transferrin saturation index - TSI) were evaluated. At the end of the experiment a piglet from each experimental unit was slaughtered and its liver and spleen removed for assessment of iron concentration by flame atomic absorption spectrometry (FAAS). The evaluated sources of iron yielded similar results for the variables of interest, but the increase in iron intake was followed by a linear increase in ADG, Hb, Ht, Fe and TSI as well as a linear decrease in the values of F:G, TR, LIBC and TIBC. Iron bioavailabilities from both ICAPC and S sources are similar for weanling piglets.
