Article Synopsis
- - The study compared two levels of forage allowance (high and low) for prepartum beef cows to assess their impact on metabolic, hormonal, productive, and reproductive variables, involving 40 primiparous (first-time mothers) and 42 multiparous (having had multiple births) cows.
- - High forage allowance improved cows' intake, energy balance, and body condition, leading to increased milk yield (5.4 kg/d vs. 4.6 kg/d) and higher calf growth rates (0.88 kg/d vs. 0.82 kg/d) compared to low forage allowance.
- - Results indicated that higher forage allowances led to better pregnancy rates (40% vs. 28%) and highlighted
Article Synopsis
- Leptospirosis, caused by diverse spirochete bacteria called Leptospira, is a neglected disease affecting both animals and humans, with limited data on its serovars in South America, particularly Uruguay.
- A 3-year study isolated and characterized 40 strains of Leptospira from infected cattle, identifying five serovars, including L. interrogans and L. borgpetersenii.
- The findings revealed that about 20% of cattle are shedding pathogenic Leptospira, posing a public health threat, and highlighted the need for improved diagnostics and understanding of the disease's epidemiology in the region.
Understanding the impact of changing pasture composition on reducing emissions of GHGs in dairy grazing systems is an important issue to mitigate climate change. The aim of this study was to estimate daily CH₄ emissions of dairy cows grazing two mixed pastures with contrasting composition of grasses and legumes: L pasture with 60% legumes on Dry Matter (DM) basis and G pasture with 75% grasses on DM basis. Milk production and CH₄ emissions were compared over two periods of two weeks during spring using eight lactating Holstein cows in a 2 × 2 Latin square design.
