Sheep Performance in Italian Ryegrass Swards at Contrasting Sward Heights

The objective of this study was to assess the effect of Italian ryegrass (Lolium multiflorum Lam.) sward height on lamb performance. The experiment was carried out at the Research Station of UFRGS, Eldorado do Sul, Brazil. Yearling no-castrated male lambs were assessed in terms of individual animal performance and gain per hectare. The experiment was carried out in a randomised block design with three replications of four treatments: 5, 10, 15 and 20 cm of sward surface height (SSH), which were maintained using continuous variable stocking, and monitored by a sward stick. Samples of 0.25 m2 were cut to ground level to estimate herbage and leaf lamina mass. Live weight gain per area and per animal increased in a quadratic pattern. The best animal production was found in a sward of approximately 15 cm high

A green coffee based product and its comparasion to commercial products regarding the antioxidant capacity

[EN] Green Coffee Products (GCP) consumption have been increased recently and is justified due its benefits to human health, as the antioxidant activity and thermogenic properties and ant mutagenic and ant carcinogenic capacity and also present alleged weight loss control. The aim this work was to elaborate a GCP with Coffea canephora by spray drying and compare its antioxidant capacity to commercial GCP samples by ORAC methodology. The results presented a range of 33.02 – 2,408.05 µmol Trolox/g for commercial products and 1,861.91 µmol Trolox/g for the product obtained in this work.We are very grateful to CAPES for scolarship for SOUZA, F.C.A. and FAPERJ for funding.Souza, F.; Souza, E.; Pontes, S.; Leal Junior, W.; Freitas-Silva, O.; Nogueira, R.

The Effect of Sward Surface Height on Sheep Grazing Activities

The objective of this study was to assess the effect of Italian ryegrass (Lolium multiflorum Lam.) sward height on grazing activities. The experiment was carried out at the Research Station of Universidade Federal do Rio Grande do Sul, Brazil. Yearling no-castrated male lambs behavior was assessed in terms of diurnal grazing, ruminating and idling time in three periods: 27 September 11 and 25 October. Sward surface height was monitored using a sward stick and samples of 0.25 m2 were cut to ground level to estimate herbage and leaf lamina mass. The experiment was carried out in a randomised block design with three replications of four treatments: sward surface heights (5, 10, 15 and 20 cm). Grazing time and ruminating time were somewhat interchangeable, decreasing grazing time and increasing ruminating time with increasing sward surface heights. Idling time remained relatively constant. Sward height showed a small effect on biting rate

Resumo

Influência da adição de soro de queijo minas frescal de cabra na aceitação de bebidas lácteas sabor chocolate preparadas com leite de cabra.

O presente trabalho teve como objetivo avaliar a aceitação de bebidas lácteas sabor chocolate preparadas com leite de cabra e soro de queijo minas frescal caprino, visando o aproveitamento do soro proveniente da produção de queijos. Pode-se concluir que as variações de percentual de soro de queijo das bebidas lácteas sabor chocolate avaliadas não são percebidas pelo consumidor, levando em conta os aspectos sensoriais estudados. A bebida que recebeu o maior percentual de soro (tratamento A) foi a melhor avaliada sensorialmente e com relação à intenção de compra, mostrando que a estratégia de aproveitamento do soro de queijos caprinos na fabricação de bebidas lácteas é eficiente
