Growth and sensory characteristics of alternative genotype broilers reared in organic orchards

The effects of age, sex and genotype on growth and sensory characteristics in organically produced broilers, when kept considerably longer before slaughtering, were examined. A total of 450 birds consisting of three genotypes, Light Sussex, New Hampshire, and the commercial strain I 657 were inserted at Fejoe Research Orchard. Half the birds were slaughtered at 91 days of age and half at 120 days of age. I 657 was significantly heavier compared to the slower growing breeds and Light Sussex was significantly heavier than New Hampshire. Males were significantly heavier than females across genotype, but weight ratios differed with genotype. No overall effect of genotype was found on the flavour or smell of the breast meat, but the commercial strain went towards a tougher and less tender consistency at 120 days of age, whereas the opposite was the case for the slower growing pure breeds. The positive flavour of salt was significantly improved at 120 days of age across genotype and age, with females having saltier flavour than the males. The positive flavour of sweet corn was improved in the meat from the males, but the positive smell of sweet corn was significantly improved in both males and females. No negative consequences of age were found

TRADE GAINS AND WELFARE COSTS OF INCOME STABILIZATION PROGRAMS FOR HOG PRODUCERS IN QUEBEC

The welfare costs of deficiency payments for an exported commodity may, under certain conditions, outweigh the gains from trade. The potential welfare impacts of stabilization programs in the hog sector in Quebec are estimated, based on a partial equilibrium framework, and elasticity estimates drawn from other sources. The results indicate that the loss in surplus in Quebec as a result of deficiency payments is very modest at approximately $8.5 million or 1.7$14 million.Livestock Production/Industries,

Statistical Modeling of Epistasis and Linkage Decay using Logic Regression

Logic regression has been recognized as a tool that can identify and model non-additive genetic interactions using Boolean logic groups. Logic regression, TASSEL-GLM and SAS-GLM were compared for analytical precision using a previously characterized model system to identify the best genetic model explaining epistatic interaction for vernalization-sensitivity in barley. A genetic model containing two molecular markers identified in vernalization response in barley was selected using logic regression while both TASSEL-GLM and SAS-GLM included spurious associations in their models. The results also suggest the logic regression can be used to identify dominant/recessive relationships between epistatic alleles through its use of conjugate operators

Graphs, Matrices, and the GraphBLAS: Seven Good Reasons

The analysis of graphs has become increasingly important to a wide range of applications. Graph analysis presents a number of unique challenges in the areas of (1) software complexity, (2) data complexity, (3) security, (4) mathematical complexity, (5) theoretical analysis, (6) serial performance, and (7) parallel performance. Implementing graph algorithms using matrix-based approaches provides a number of promising solutions to these challenges. The GraphBLAS standard (istc- bigdata.org/GraphBlas) is being developed to bring the potential of matrix based graph algorithms to the broadest possible audience. The GraphBLAS mathematically defines a core set of matrix-based graph operations that can be used to implement a wide class of graph algorithms in a wide range of programming environments. This paper provides an introduction to the GraphBLAS and describes how the GraphBLAS can be used to address many of the challenges associated with analysis of graphs.Comment: 10 pages; International Conference on Computational Science workshop on the Applications of Matrix Computational Methods in the Analysis of Modern Dat
