Methods to determine forage intake by lambs on Italian ryegrass Animal Sciences
Rosa, Aline Tatiane Nunes da; Rocha, Marta Gomes da; Pötter, Luciana; Graminho, Larissa Arnhold; Bergoli, Tuani Lopes; Moterle, Paulo Henrique.
This study was conducted to evaluate the use of chromium oxide and the content of fecal nitrogen to estimate forage intake by female lambs on Italian ryegrass pasture. The pasture was managed under different forage allowances (FA): 6, 9 and 12% BW. The experiment was a randomized split-split plot design, in which the forage allowances were considered as main plots, the phenological stages as subplots and methods to determine intake as sub-subplots. Forage intake, in the ryegrass vegetative stage, is independent of forage allowance. Lower allowances limit forage intake from the pre-flowering stage, while at the reproductive stage, intake was lower in FA6, intermediate in FA9 and higher in FA12. The estimation of organic matter intake by lambs on Italian...

Roso, Dalton; Rocha, Marta Gomes da; Pötter, Luciana; Sichonany, Maria José Oliveira; Rosa, Aline Tatiane Nunes da; Souza, Alexandre Nunes Motta de.
 Productive and reproductive performance of beef heifers grazing on Italian ryegrass (Lolium multiflorum Lam.) were analyzed, comprising animals exclusively on pasture and supplemented animals with extruded fat (0.15 or 0.30% of body weight). The grazing method was continuous with variable stocking rate. The experimental design was completely randomized following a repeated measure arrangement. Variables related to pasture were similar when the heifers received different supplementation levels, with similar grazing conditions. Mean values of forage mass and canopy height were 1,500 kg DM ha-1 and 17 cm, respectively. Heifers ingested forage with a similar content of crude protein (21.90%) and neutral detergent fiber (49.30%), regardless of supplementation...

The increasing demand for propolis has caused a raise in its production. However, an increasingly pesticide-dependent agriculture is a great concern with regard to bees, their produce and environmental contamination. Current analysis evaluates the presence of pesticides (organochlorines, organophosphates, pyrethroids, carbamates, herbicides, fungicides and acaricides) in samples of propolis from the state of São Paulo, Brazil. Beekeepers from several localities in the state provided samples of propolis (50), which were collected, stored in non-toxic plastic bags and maintained in a freezer for analyses. Possible pesticide residues were examined by gas chromatography method but no pesticide residues were detected in the examined propolis samples. Propolis...

This study was realized to evaluate the production and economic viability of finished beef cattle in feedlot in the Cerrado biome of Piauí State, Brazil. One hundred and fifty cattle -50 bulls (B) with an body weight of 283.0 ± 20.82 kg, at 30 months of age; and 100 cull cows (CC) with an body weight of 296.1 ± 17.80 kg, at 100 months of age- were used in a completely randomized design. The animal performance indicators for the evaluation of economic viability were initial age (months), slaughter age (months), was initial body weight (kg), final body weight (kg), daily feed intake (kg animal-1; kg kg-1 BW), diet cost (R$ kg-1 of diet), cost of kg produced (R$ kg-1 produced), and average price of the kg of meat for finishing (R$). The CC consumed more...
