Allometry of litter size in dog breeds [PDF]
Acta Veterinaria ScandinavicaLitter size varies among dog breeds and is related to body size. Generally, the relationship is described as small breeds having smaller litters, and larger breeds larger litters, though the trend does not extend to very large breeds.

The Evolution of Primate Litter Size
HumansLitter size plays an essential role in mammalian evolution and is one of the most important factors determining whether an organism is deemed to have a ‘slow’ or ‘fast’ life history strategy.

A genetic tool to manipulate litter size [PDF]
Frontiers in Zoology, 2014 Introduction 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 ...

A review of factors influencing litter size in Irish sows [PDF]
Irish Veterinary Journal, 2007 Many factors influence litter size. These include genetics, gilt management, lactation length, parity distribution, disease, stress and boar fertility. In the past 20 years, litter size in Irish sows has increased by only one pig.

Analysis of Litter Size and Average Litter Weight in Pigs Using a Recursive Model [PDF]
Genetics, 2007 Abstract An analysis of litter size and average piglet weight at birth in Landrace and Yorkshire using a standard two-trait mixed model (SMM) and a recursive mixed model (RMM) is presented. The RMM establishes a one-way link from litter size to average piglet weight.

Correlation of litter size traits [PDF]
Biotechnology in Animal Husbandry, 2016 Heredity and correlation of litter size traits were observed in 3693 litters, i.e. in 1622 daughters of two genotypes Swedish Landrace genotype - SL; and F1 ♀ SLxLW. The study included daughters (minimum ten daughters per sire) of 24 sires.

Effects of experimental fires on litter decomposition in a seasonally dry Amazonian forest. [PDF]
, 2009 Litter decomposition is a fundamental process for nutrient cycling but we have a limited understanding of this process in disturbed tropical forests. We studied litter decomposition over a 10-mo period in a seasonally dry Amazon forest in Mato Grosso ...
