Genetic relationship between milk urea nitrogen and reproductive performance in Holstein dairy cows
Animal, 2011 The objective of this study was to describe the genetic and phenotypic relationship between milk urea nitrogen (MUN) and reproductive traits in Iranian Holstein dairy cows. Test-day MUN data obtained from 57 301 dairy cows on 20 large dairy herds in Iran

Analysis of reproductive performances during the formation of a synthetic rabbit strain [PDF]
, 2005 [EN] In 1995, a synthetic rabbit strain ('2666') was formed at INRA for commercial meat purposesby crossing the INRA '2066' strain and the 'V' strain from the Polytechnical University of Valencia (Spain).The development of some reproductive traits and ...

Allometry Between Vegetative and Reproductive Traits in Orchids [PDF]
Frontiers in Plant Science, 2021 In flowering plants, inflorescence characteristics influence both seed set and pollen contribution, while inflorescence and peduncle size can be correlated with biomass allocation to reproductive organs. Peduncles also play a role in water and nutrient supply of flowers, and mechanical support.

Genetic evaluation of fertility using direct and correlated traits [PDF]
, 2003 Poor fertility has become a major reason for involuntary culling of dairy cows in the United Kingdom. Calving interval (CI) and body condition score (BCS) are recorded, heritable, genetically correlated with each other, and could be used to extend the ...

Genetic correlations among protein yield, productive life, and type traits from the United States and diseases other than mastitis from Denmark and Sweden [PDF]
, 1999 Sire genetic evaluations for protein yield, productive life, and selected type traits from the US were correlated with sire evaluations for disease from Denmark and Sweden and were then adjusted to approximate genetic correlations.

Heterosis of growth and reproductive traits in fowl
Poultry Science, 2002 Long-term divergent selection for high (HH) and low (LL) BW at 56 d of age in White Plymouth Rock chickens resulted in deviations from a typical chronological timeline for reproductive development. Line HH chickens of the 42nd generation of selection (S(42)) were heavier at 28, 56, 168, and 266 d of age, as well as at sexual maturity than those from ...

Assisted reproductive technology in the USA: is more regulation needed? [PDF]
, 2014 The regulation of assisted reproductive technologies is a contested area. Some jurisdictions, such as the UK and a number of Australian states, have comprehensive regulation of most aspects of assisted reproductive technologies; others, such as the USA ...

Exploring the non-genetic factors that affect reproduction traits of Saanen Goats in Indonesia
Journal of Agriculture and Rural Development in the Tropics and Subtropics, 2023 Adjustment of trait records for different non-genetic factors increases the accuracy of genetic parameters and enables more accurate selection. This study aimed to investigate the non-genetic factors affecting reproductive traits in Saanen goats at the ...

Mutation independently affects reproductive traits and dauer larvae development in mutation accumulation lines of Caenorhabditis elegans [PDF]
, 2017 Developmental decisions are important in organismal fitness. For the nematode Caenorhabditis elegans, which is naturally found in the ephemeral food patches formed by rotting plant material, correctly committing to dauer or non-dauer larval development ...
