Effect of MGA on Performance, Sexual Behavior, Carcass Quality and Tenderness in Mixed-Sex Pens of Cattle

The effect of MGA in mixed pens of steers and heifers was evaluated over a three-year period at the ISU Armstrong Research Farm near Lewis, Iowa. Two pens of approximately 40 head were fed diets with or without MGA in each of three replications. Estrus and riding activity was monitored using the Heat Watchâ system. At slaughter, in addition to routine carcass data collection, a rib sample was collected from each carcass for tenderness evaluation. There was no effect on dry matter intake due to MGA treatment. Mixed-sex pens that were fed MGA were 4% more efficient than controls. MGA-fed steers gained similarly to control steers. MGA fed heifers gained 8% faster than control heifers. MGA highly reduced measures of estrus and riding activity throughout the feeding period. MGA feeding improved marbling and tenderness measured in both steers and heifers. These data suggest that MGA has potential to improve performance, quality grade and tenderness in mixed pens of steers and heifers.

Prediction of Benthic Impact for Salmon Net-Pens Based on the Balance of Benthic Oxygen Supply and Demand

The ratio between oxygen supply and oxygen demand was examined as a predictor of benthic response to organic enrichment caused by salmon net-pen aquaculture. Oxygen supply to the benthos was calculated based on Fickian diffusion and near-bottom flow velocities. A strong linear correlation was found between measured carbon sedimentation rates and rates of benthic metabolism. This relationship allowed an estimation of oxygen demand based on sedimentation rates. Comparison of several production sites in Maine (USA) coastal waters showed that for sites where oxygen demand exceeded supply benthic impacts were high and for sites where oxygen supply exceeded demand benthic impacts were low. These findings were summarized in the form of a predictive model that should be useful in siting salmon production facilities.

Efeitos do transporte e do tempo de espera no bem-estar e na qualidade de carne de cordeiros

Com este estudo objetivou-se avaliar os níveis de estresse e a qualidade de carne de cordeiros mestiços Santa Inês x Dorper, submetidos a transporte de percurso curto (duas horas) e longo (seis horas) e em dois períodos de espera pré-abate (12 ou 24 horas). Foram utilizados 32 cordeiros com 127 ± 7 dias de idade e 30,4 ± 2,1 kg de peso vivo. Antes de serem submetidos aos períodos de transporte, os animais estavam alocados em baias coletivas e receberam ração concentrada (farelo de soja e milho, calcário calcítico e núcleo com monensina), bagaço úmido de citros e capim Napier (Pennisetum purpureum) e água ad libitum. Foram realizadas avaliações de reatividade dos animais no momento do embarque, desembarque e durante a contenção dos animais para as colheitas de sangue, urina e temperatura ocular por termografia infravermelho. Durante o período de espera pré-abate, realizou-se a colheita de dados comportamentais dos animais. Foram avaliadas as concentrações de cortisol no soro, na urina e as concentrações de haptoglobina no soro nos períodos que antecederam a insensibilização, assim como no momento do abate. Os animais apresentaram baixa reatividade durante todos os manejos. Houve diferença significativa no comportamento dos cordeiros durante os períodos de espera (P < 0,05) que durante as 12 horas apresentaram frequência de comportamentos que indicaram bem-estar favorável, enquanto que o período de transporte não afetou (P > 0,05). Os níveis de cortisol no soro mantiveram-se semelhantes da saída dos animais para o transporte até o final do período de espera (P > 0,05), enquanto houve oscilação dessas concentrações no cortisol na urina (P < 0,05), com pico no desembarque dos animais de duas horas de transporte e diminuição ao final do período de descanso. Os níveis de haptoglobina mantiveram-se semelhantes da colheita realizada antes do transporte, no embarque e no desembarque (P > 0,05) e diminuíram no final do período de espera pré-abate (P < 0,05). A temperatura ocular elevou-se no embarque e no desembarque dos animais, com diminuição da temperatura ao final do período de espera (P < 0,05). No momento do abate, foi observado aumento das concentrações de haptoglobina (P < 0,05), enquanto não houve alteração nas concentrações de cortisol no soro (P > 0,05). Animais que permaneceram por 24 horas de espera pré-abate apresentaram maior força de cisalhamento e menor luminosidade (L*) e intensidade de amarelo (b*). As variáveis comportamentais foram pouco afetadas pelos períodos de transporte e de espera pré-abate, porém o período de 12 horas de espera favoreceu a qualidade da carne

A comparative study to evaluate surface microbial contamination associated with copper-containing and stainless steel pens used by nurses in the critical care unit

A clinical study was undertaken to compare the surface microbial contamination associated with pens constructed of either a copper alloy or stainless steel used by nurses on intensive care units. A significantly lower level of microbial contamination was found on the copper alloy pens. Copyright © 2011 by the Association for Professionals in Infection Control and Epidemiology, Inc.

Influence of stocking densities in the nursery phase on the growth of Macrobrachium amazonicum reared in net pens

The Amazon river prawn (Macrobrachium amazonicum) is a native species with great potential for aquaculture, based on promising results obtained from experimental culture trials in Brazil. The influence of different stocking densities on the development of prawns reared in cages in the nursery phase as well as on their growth when transferred to grow-out net pens at lower densities was evaluated. In the nursery phase, juveniles I (0.157 +/- 0.014 g, 47 days old) were stocked in 0.5 m(-2) cages at densities of 400, 800 and 1200 m(-2). After 71 days, prawns were transferred to grow-out net pens of 2.0 m(-2), at a density of 20 juveniles II m(-2). The treatments were determined by the mean weights registered for the prawns (118 days old) previously stocked at 400, 800 and 1200 juveniles I m(-2) in the nursery phase: 0.94 +/- 0.07 g (T1), 0.61 +/- 0.04 g (T2) and 0.48 +/- 0.07 g (T3), respectively. In the nursery phase, mean survival was above 96%, whereas mean weights were significantly higher (P<0.05) for the density of 400 prawns m(-2). The highest biomass (276.7 g) and productivity (1152 juveniles II m(-2)) were registered at the density of 1200 prawns m(-2), differing significantly (P<0.05) from the lower densities. One month after the transfer of the animals to the net pens, there was recovery in the specific growth rate (SGR) of prawns in all treatments which was significantly higher (P<0.05) in T3 (4.01 +/- 0.36% day(-1)) and T2 (3.60 +/- 0.18% day(-1)). The feed conversion efficiency (FCE) in the first month after the transfer was also significantly higher (P<0.05) in T3 (78.2 +/- 19.1%) when compared to T1 (39.8 +/- 9.5%). These results suggest the occurrence of a compensatory growth in M. amazonicum after transferring them to lower densities, which can point out high densities for nursery cages as a viable practice. After 277 days of grow-out phase in net pens in the cold season, survival, mean weight and biomass did not differ significantly among the treatments, indicating the viability of using net pens in stocking prawns during autumn and winter, since the minimum temperature does not drop below 17 degrees C. Influence of stocking density during the nursery phase on the grow-out of prawns was not observed. The population structure in prawns reared in net-pens was similar to that observed in earthen ponds.

Personality, motivation and video games

This study explored relationships between personality, video game preference and gaming experiences. Two hundred and thirty-five participants completed an online survey in which they recalled a recent gaming experience, and provided measures of personality and their gaming experience via the Player Experience of Need Satisfaction (PENS) measure. Relationships between game genre, personality and gaming experience were found. Results are interpreted with reference to the validity of the PENS, current models of video gaming motivations and enjoyment, and sub-groups of people that may be more vulnerable to possible negative effects of games.
