EFFECT OF INBREEDING ON THE PERFORMANCE OF LARGE WHITE YORKSHIRE SOWS [PDF]
Journal of Veterinary and Animal Sciences, 2004 Data relating to 130 sows, 19 boars from 400 farrowings spread over a period from 1984 to 1992 were utilized to study genetic and non-genetic effects on variation of litter size at birth and litter size at weaning.

Transcriptomic Analysis of Ovaries from Pigs with High And Low Litter Size.
PLoS ONE, 2015 Litter size is one of the most important economic traits for pig production as it is directly related to the production efficiency. Litter size is affected by interactions between multiple genes and the environment.

Are opportunistic captures of neonate ungulates biasing relative estimates of litter size?
Animal Biotelemetry, 2022 The capture of neonate ungulates allows for the collection of valuable ecological data, including estimates of litter size. However, varied methods used to capture neonate ungulates can result in sampling biases.

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 ...

LITTER SIZE AND THE DURATION OF PREGNANCY IN MICE [PDF]
Quarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1968 Analysis of the data from 1246 dated mouse pregnancies revealed an inverse relationship between litter size and gestation period which, however, was not continuously linear over the range of litter sizes as previously shown [Biggers et al., 1963], but was mostly evident as an increase in mean duration with litters below modal size.
