چکیده

Pasture systems for grass-fed beef production in the Gulf Coast region were evaluated for profitability and sustainability over the period 2009/2010 to 2011/2012. May-weaned steers were divided into groups and randomly placed into different pasture systems. Data on input usage, output quantities, and carbon emissions were recorded and analyzed. The least complex grazing system yielded higher profit than the most complex, but the most complex produced the lowest greenhouse gas impact. A trade-off was found between profitability and greenhouse gas impact among the systems.

Carcass Traits and Tenderness of Grass-fed Beef from Subtropical Pastures in Hawaii

Introduction The “Grass-fed beef ” label indicates meat that is produced by feeding forages from start to finish without any grain supplementation (USDA-AMS 2007). Many healthful aspects of grass-fed beef have been identified, including lower total fat content and higher content of omega-3 fatty acids, conjugated linoleic acids (CLA), and antioxidants as compared to feedlot-finished beef (Razmi...

The base of this review is to consider the relevant role that animal factors (potential milk yield, body weight, body condition score, state of lactation, parity and fertility) play on milk performance (considering the energy balance and the rumen function across the full lactation curve of animals) and milk quality (milk protein content, milk fat content, milk lactose content, vitamins, minera...

Improving Dry-matter Intake of Perennial-ryegrass Pasture by Dairy Cows

Dairy cows fed on perennial-ryegrass pasture produce higher-quality milk in terms of fatty-acid composition; however, they produce much less milk compared to dairy cows under other systems. The low dry-matter intake (DMI) has been identified as the main factor responsible for the lower milk production in pasture-based systems. To maximize milk production from those systems it is important to ma...
