The genetic correlations among body weight (BW) at 28 days interval during the first year, and between reproductive traits and BW, were estimated using a multivariate animal model. The data consisted of BW at 168, 196, 224, 252, 280, 308, 336 and 364

A system for automatic registration and individual recognition of feed pecking (activity and quantity) in groups of free running hens was tested. A PIT (Passive Integrated Transponder)-tag system was used to separate and register individuals when the

The phenotypic and genetic characteristics of female spawning date and age at spawning within season were studied by analysing data from rainbow trout populations in which females spawned completely within the second year. Spawning date was measured

Summary Data from 20 249 Baluchi lambs, recorded from 1966 to 1989 in the Abbasabad Sheep Breeding Station located in the north-east of Iran (Mashhad), were used to investigate the influences of environmental factors, multiplicative and additive adju

The variation and covariation of reproductive traits were studied by analyzing data from 2020 females divided into 377 full sib families and covering five generations of three lines—a random mated control line (C), an egg size (+) line (E) and a bo

Design of control populations to be used in the simulation studies of assortative mating is discussed. In order to be useful for 25 generations a control population should satisfy the following requirements: (i) phenotypic correlation of mates, r P,

Rate of inbreeding and inbreeding effects on body weight and reproductive traits were studied in three lines of rainbow trout from a Californian selection experiment, in which Line Y was selected for body weight at 364 days of age, Line E was selecte
