Genetic analysis of postpartum measures of luteal activity in dairy cows

, 2007
The objective of this study was to estimate genetic parameters for measures of luteal activity during the first 60 d postpartum. Analyses were made with different sampling intervals to investigate the possibility of combining progesterone measurement ...

Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

Journal of Fish Diseases, EarlyView.
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...

Genetic and phenotypic relationships among endocrine and traditional fertility traits and production traits in Holstein-Friesian dairy cows

, 2002
The objective of this study was to estimate the heritability of a number of traditional and endocrine fertility traits in addition to d-56 predicted milk yield (MY56), and the genetic and phenotypic correlations between these traits.

Rural Capitalists and Development in Colonial Africa: A Comparative Analysis

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper explores the emergence and role of rural capitalists in colonial Sub‐Saharan Africa by comparing three peasant‐based economies: Bechuanaland, the Gold Coast and Tanganyika. Using social tables, we estimate the population and income shares of better earning agricultural producers and assess their impact on rural inequality and ...

Effects of Prepartum Supplementation and Yeast Fermentation Products on the Progesterone‐Modulated Transfer of Passive Immunity in Bos indicus Cows

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Inadequate colostrum intake increases risks of calf morbidity and mortality. This study investigated the effects of prepartum and early postpartum supplementation and yeast fermentation products on late‐pregnant Bos indicus cows, and the role of progesterone in mediating passive immunity transfer.
