animal models are used to model the observations of animal performance that are genetically dependent.these models are considered as generalized linear mixed models and the genetic correlation structure of data is considered through random effects of breeding values. one goal of the mentioned models is to estimate variance components. in this research, an approximate bayesian approach presented...
World population growth and food demand have been two major elements leading to the expansion of animal and fish production. Recently, many efforts advocated the extension of intensive fish farming to optimize the need for animal protein (Hussein et al., 2013). In Korea, aquaculture has made rapid development in a short period of time, and many fish farms have been established in order to fulfi...
UNLABELLED The open-data scientific philosophy is being widely adopted and proving to promote considerable progress in ecology and evolution. Open-data global data bases now exist on animal migration, species distribution, conservation status, etc. However, a gap exists for data on population dynamics spanning the rich diversity of the animal kingdom world-wide. This information is fundamental ...
Individually distinct acoustic features have been observed in a wide range of vocally active animal species and have been used to study animals for decades. Only a few studies, however, have attempted to examine the use of acoustic identification of individuals to assess population, either for evaluating the population structure, population abundance and density, or for assessing animal seasona...

The generation of co-products continues at an accelerating pace, driven by population growth. Many of these co-products can be included in ruminant feed, which has the ability to transform them into good quality animal protein, and also help to reduce the disposal of undesirable residues to the environment. One of the co-products with potential use in animal feed, the citrus pulp, represents re...
