Abstract

Purpose: The purpose of this paper is to investigate information asymmetry in cattle supply transaction in Brazil. While the literature traditionally explores the seller's information asymmetry advantages, the authors, in turn, draw attention to buyer's role. This paper aims to show what farmer...

Abstract

The objective was to estimate genetic correlations for persistency, milk yield and somatic cell score (SCS) in Holstein cattle in Brazil. A dataset with 190389 records of test-day milk and of test-day SCS from 21824 cows was used. Two-trait random regression model with a fourth order Legendre...

Abstract

The objective of the present work was to evaluate the effect of somatic cell score on the longevity of Holstein cows raised all over Brazil, using a piecewise Weibull proportional-hazard model. The following two longevity traits were defined: true longevity, number of days from first calving to...

Abstract

Animal transportation and pre-slaughter procedures are major components of the beef production system, but cattle are especially susceptible to stress during those events. In addition to stress-induced meat quality problems that might occur, such as higher pH and DFD meat, stressed animals are more ...

Abstract

Concerns about global climate change has become increasingly apparent with increasing debates and discussions on the subject at an international level. Brazilian cattle effective is the largest commercial herd in the world, emitting about 50 kg of methane per animal each year. Considering this...

Abstract

The objective of this study was to investigate the population genetic structure and the effects of inbreeding on growth traits of Nellore breed animals from the Amazon biome. The database used for the analyzes contained records of 1,402,287 animals born between the years of 1950 and 2012 and weight ...

Abstract

A mix of public policy and market interventions in the mid-2000s led to historic reductions in deforestation in the Brazilian Amazon. The collateral impact of these forest conservation policies on agricultural production is still poorly understood, though evidence is sorely needed given the...

Abstract

New models for renewable energy production are needed to simultaneously decrease greenhouse gases (GHG) emissions, use land more efficiently and replace large amounts of fossil fuel. Ethanol production and livestock feed integration as practiced in the United States (USA) is one model for ethanol...

Abstract

The objective of the study was to determine the factors related to beef cattle carcass bruises. Handling, transportation and unloading data from cattle purchased by a slaughterhouse in southern Brazil were obtained to assess their associations with carcass bruising (occurrence or not) and the...

Abstract

Test-day milk, fat and protein yields and somatic cell score (SCS) of Brazilian Holstein cattle were used to study the effect of fixed (HTDF) vs random (HTDR) contemporary groups (herd-test-date) with or without unknown parent groups (UPG) using an autoregressive test-day animal model for genetic...
