Barriers To Management Intensive Grazing By Southern Dairy Farmers, Mohammed Ibrahim, Nalini K. Pattanaik, Brian Cornish

Professional Agricultural Workers Journal

Abstract

Interest in Management Intensive Grazing (MIG) [a situation where grazing animals are moved to a fresh pasture every few days in order to have access to adequate forage] practices by farmers have increased steadily over the years. Many research publications on grazing advocate the financial and environmental benefits of grazing. Understanding the challenges of MIG can be an important piece of information for a dairy farmer. A survey was conducted to determine how farmers in the southeastern region perceive the barriers to the adoption of MIG. A greater percentage of MIG southeastern farmers were satisfied or very satisfied with …

Genetic Variation Of The Dgat1 Gene In Dual-Purpose Dairy Cows And Its Influence On Economically Important Breeding Traits, Mark E. Armitage, Emma Swan, Denise O'Meara

SURE Journal: Science Undergraduate Research Experience Journal

Background
Over the last 10 years, the discovery of individual, or candidate, genes that influence economically important traits has revolutionised how the dairy industry selects cows for breeding programmes. One such gene, the diacylglycerol O-acyltransferase 1 (DGAT1) gene is significant in dairy production as it is associated with the synthesis of fat in milk, and polymorphisms within the gene can be used for selection purposes. In this study, the variants (genotypes) of the K232A polymorphism of the DGAT1 gene, within a dual-purpose dairy herd, bred for both dairy and beef production, were determined, and compared to the Economic …
