Bovine respiratory disease (BRD) is a common global health problem in dairy cattle. The definitive diagnosis of BRD is complex because its etiology involves several predisposing and determining factors. This report describes the etiology of a BRD outbreak in a dairy herd in the mesoregion of Centr...
In a set of opinions released in 2018, the State Council set out a range of goals to increase the production of dairy by opening up new areas of the country to milk production, such as the south of China, improving cattle breeding systems, and implementing technologies such as the Internet...
There are a number of key areas for improving fertility management these include: i) handling of substantial volumes of data, ii) genetic selection (including improved phenotypes for use in breeding programmes), iii) nutritional management (including transition cow management), iv) control of infecti...

dairy cattle fully housed Jersey crossbreds grassland systems INTRODUCTION Although grassland-based milk production systems are common in many parts of the world, including within cool temperate regions of western Europe, there is much variation in systems adopted between and within grassland regions. For...
Melvin talked about his own progress toward a herd now 75% A2 through the bulls he selects for breeding. In his quiet manner, he demonstrated the reassuring message about how dairy farmers are always looking to improve and put their best quality forward. -30- Share this Tweet Email Print ...

DAIRY cattleNUTRITIONAL statusRICEANTHOCYANINSThe study aimed to evaluate the impact of black rice and purple corn extracted residue (BPER) on feed intake, nutrient digestibility, growth performance, and antioxidant activity in male dairy cattle. The residue after extraction ...
Such disruption in luteal function near the breeding period, observed here as abnormal LP or decreased P4 concentrations, possibly contributes to reduced fertility. We observed a higher prevalence of prolonged LP (50%) than reported previously (12 to 20%; Opsomer et al., 1998; Ranasinghe et ...
Each insemination was recorded on a handheld computer and exported to the Irish Cattle Breeding Federation (ICBF) database, which is the national repository for cattle data in Ireland. Insemination data and other animal information, including date of previous calving, parity, economic breeding index ...
