The Herfindahl neutral point: A firm‐level threshold for managing market concentration with evidence from US hog packing

American Journal of Agricultural Economics, EarlyView.
Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Nutritional parameters and production of calves on pasture supplemented with different sources of protein foods

Semina: Ciências Agrárias, 2014
The aim of this study was to evaluate the effects of multiple supplements with different protein sources on the performance, intake, nutrient digestibility, and microbial protein production efficiency of lactating beef heifers under grazing.

Temporal and seasonal trends of bovine tuberculosis in the Irish cattle population (2008–2024)

Veterinary Record, EarlyView.
Abstract Background Bovine tuberculosis (bTB) has substantial impacts on the Irish cattle industry. Between 2016 and 2024, its burden increased in Irish cattle. As an initial step towards understanding drivers of this increase, we explore long‐term trends in measures of bTB burden and cattle demographics in Ireland. Methods Using data from 2008 to 2024,

Transcriptome profiles in peripheral white blood cells at the time of artificial insemination discriminate beef heifers with different fertility potential

BMC Genomics, 2018
Background Infertility is a longstanding limitation in livestock production with important economic impact for the cattle industry. Female reproductive traits are polygenic and lowly heritable in nature, thus selection for fertility is challenging.

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

Agricultural and Forest Entomology, EarlyView.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Production and economic traits of purebreed and crossbred animals in diary herds of mountain areas [PDF]

, 2013
Beef production from dairy herds represents an alternative source to improve the farm profitability. The use of beef semen to mate cattle not destined to breed replacement represent an interesting source of income for dairy farmers particularly due to ...

Population Differentiation and Polygenic Selection in the Finnish Ayrshire Cows Selected on Genomic Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...
