AlphaSim: Software for Breeding Program Simulation.
This paper describes AlphaSim, a software package for simulating plant and animal breeding programs. AlphaSim enables the simulation of multiple aspects of breeding programs with a high degree of flexibility. AlphaSim simulates breeding programs in a series of steps: (i) simulate haplotype sequences and pedigree; (ii) drop haplotypes into the base generation of the pedigree and select single-nu...
متن کامل15. Breeding Program Design Principles
Objectives to target: This relates to asking ‘Where to go?’, whereas Tools and Strategies below relate to ‘How to get there?’ Breeding objectives describe the type of animal that we might want to develop, or, more commonly, describe the utility of marginal genetic changes in each trait of commercial value. However, there is increasing concern about loss of genetic diversity, both within and b...
متن کاملBreeding and Genetics: Dairy Cattle Breeding I
Humans obtain a number of products from animals. These include food, clothing, medical materials, companionship and research knowledge to name a few. A valued ethic contends that it is inappropriate for one to treat another as a means to an end. In short, it is wrong to treat another as simply a product. Historically, non-human beings have not been included as “others” and thus their treatment ...
متن کاملBreeding and Genetics: Dairy Cattle
Protein-damaging stresses, including heat shock, cold, altered pH and oxygen deprivation induce the expression of a subgroup of molecular chaperones, called heat shock proteins (Hsp), which consist of several protein families designated by their molecular weight, such as the Hsp90, Hsp70, Hsp60, and the small Hsp (sHsp) families. Small heat shock proteins (sHsp) with a molecular mass of 15–30 k...
متن کاملConsequences for Dairy Cattle Breeding
Advances in breeding and management resulted in a considerable increase of production traits in Austrian dairy cattle. Besides, low input systems were also established. Possible genotype by environment interactions (G x E) and genetic antagonisms dependent on production level might indicate the need for separate breeding programmes for dairy farms diff ering in management intensity. Th us, G x ...
