Size Does Matter: Litter Size Strongly Determines Adult Metabolism in Rodents [PDF]

Cell Metabolism, 2020
In this essay, we highlight how litter size in rodents is a strong determinant of neonatal growth and long-term metabolic health. Based on these effects, we strongly advise that scientific articles that utilize rodent models for obesity and metabolic research should include information on the litter sizes in the study to increase the data transparency ...

Hypomethylation in the promoter region of ZPBP as a potential litter size indicator in Berkshire pigs [PDF]

Archives Animal Breeding, 2019
In pigs, litter size is typically defined as the total number of piglets born (TNB) or the number of piglets born alive (NBA). Increasing pig litter size is of great economic interest as a means to increase productivity.

Identifying early indicator traits for sow longevity using a linear-threshold model in Thai Large White and Landrace females [PDF]

Animal Bioscience, 2021
Objective The objective of the study was to investigate the possibility of utilizing an early litter size trait as an indirect selection trait for longevity and to estimate genetic parameters between sow stayability and litter size at different parities ...

Single Nucleotide Polymorphisms in the HIRA Gene Affect Litter Size in Small Tail Han Sheep

Animals, 2018
Maintenance of appropriate levels of fecundity is critical for efficient sheep production. Opportunities to increase sheep litter size include identifying single gene mutations with major effects on ovulation rate and litter size. Whole-genome sequencing

Genetic variants of the bone morphogenetic protein gene and its association with estrogen and progesterone levels with litter size in Awassi ewes [PDF]

Iraqi Journal of Veterinary Sciences, 2022
This research aimed to assess the genetic polymorphism of the BMP15 gene concerning sex hormone levels and birth type in Awassi ewes. The genome DNA of 138 Awassi ewes was isolated (52 ewes produced a singleton and 86 produced twins). The BMP15 gene exon-

A genetic tool to manipulate litter size [PDF]

Frontiers in Zoology, 2014
Experimental litter size manipulations are often not problem free. Typically conducted shortly after birth or oviposition, they do not account for the energy already invested into the production of the offspring. Such effects make it difficult to interpret the results from experimental litter size manipulations and therefore to study optimality of ...

Selection for environmental variance of litter size in rabbits

Genetics Selection Evolution, 2017
Background In recent years, there has been an increasing interest in the genetic determination of environmental variance. In the case of litter size, environmental variance can be related to the capacity of animals to adapt to new environmental ...

Sample size requirements for riverbank macrolitter characterization

Frontiers in Water, 2023
Anthropogenic litter is omnipresent in terrestrial and freshwater systems, and can have major economic and ecological impacts. Monitoring and modeling of anthropogenic litter comes with large uncertainties due to the wide variety of litter ...

Selection for litter size components: a critical review [PDF]

Genetics Selection Evolution, 1997
The measurement of component variables such as the number of ova shed (OR) and its inclusion in a linear index with litter size (LS) or prenatal survival has been suggested in order to accelerate genetic progress for LS. Despite optimistic theoretical predictions, however, in no selection experiment has the advantage of including OR in an index as ...
