Genetic parameters for the external udder morphology in commercial farms of Istrian sheep from Croatia [PDF]

Journal of Central European Agriculture, 2019
Istrian sheep is a local breed with superior milk yield and composition. Excellent udder shape of this breed needs to be preserved in future, since it’s economic value resides within the artisanal cheese production. Genetic parameters for the teat angle (

Key Genetic Parameters for Population Management [PDF]

Frontiers in Genetics, 2019
Population management has the primary task of maximizing the long-term competitiveness of a breed. Breeds compete with each other for being able to supply consumer demands at low costs and also for funds from conservation programs. The competition for consumer preference is won by breeds with high genetic gain for total merit who maintained a ...

Genetic parameters estimation for preweaning traits and their relationship with reproductive, productive and morphological traits in alpaca

Animal, 2017
The aim of this study was to estimate the genetic parameters for preweaning traits and their relationship with reproductive, productive and morphological traits in alpacas. The data were collected from 2001 to 2015 in the Pacomarca experimental farm. The

Different Tools on Multi-Objective Optimization of a Hybrid Artificial Neural Network – Genetic Algorithm for Plasma Chemical Reactor Modelling [PDF]

, 2012
A hybrid ANN-GA was successfully developed to model, to simulate and to optimize simultaneously a catalytic–DBD plasma reactor. The integrated ANN-GA method facilitates powerful modeling and multi-objective optimization for co-generation of synthesis ...

Genomic Analysis of Milk Protein Fractions in Brown Swiss Cattle

Animals, 2020
Depending on whether milk protein fractions are evaluated qualitatively or quantitatively, different genetic outcomes may emerge. In this study, we compared the genetic parameters for the major milk protein fractions—caseins (αS1-, αS2-, &

Genetic and Environmental Parameters of Milk Constituents for Five Breeds. II. Some Genetic Parameters

Journal of Dairy Science, 1968
Abstract Estimates were made of some genetic parameters of milk yield and its components and of the breeding values of sires for yields and constituent percentages. The data consisted of 1.449 cows of the Ayrshire, Guernsey, Holstein, Jersey, and Brown Swiss breeds located in 43 herds.

Loading as a design parameter for genetic circuits [PDF]

2016 American Control Conference (ACC), 2016
A significant problem when building complex biomolecular circuits is due to context-dependence: the dynamics of a system are altered upon changes to its context, potentially degrading the system's performance. Here, we study retroactivity, a specific type of context-dependence, by analyzing the effects of loads on a transcription factor applied by the ...

A rigorous evaluation of crossover and mutation in genetic programming [PDF]

, 2009
The role of crossover and mutation in Genetic Programming (GP) has been the subject of much debate since the emergence of the field. In this paper, we contribute new empirical evidence to this argument using a rigorous and principled experimental method ...

Selection of early lima bean lines for grain yield

Pesquisa Agropecuária Tropical
The scarcity of improved lima bean (Phaseolus lunatus L.) cultivars in Brazil has made it difficult to reach new production levels. This study aimed to select early and high-yielding lima bean lines with commercially desirable seed traits.

The Complex Parameter Landscape of the Compact Genetic Algorithm [PDF]

Algorithmica, 2020
AbstractThe compact Genetic Algorithm (cGA) evolves a probability distribution favoring optimal solutions in the underlying search space by repeatedly sampling from the distribution and updating it according to promising samples. We study the intricate dynamics of the cGA on the test functionOneMax, and how its performance depends on the hypothetical ...
