Mapping Prolificacy QTL in Maize and Teosinte [PDF]

Journal of Heredity, 2016
Teosinte, the ancestor of maize, possesses multiple ears at each node along its main stalk, whereas maize has only a single ear at each node. With its greater ear number, teosinte is referred to as being more prolific. The grassy tillers 1 (gt1) gene has been identified as a large-effect quantitative trait locus underlying this prolificacy difference ...

Validation Study of c.746A>G SNP of BMPR1B Gene Associated with Litter Size in Sheep Genetic Resources of Bangladesh

Journal of Advanced Biotechnology and Experimental Therapeutics, 2022
The BMPR1B gene is one of the major fecundity genes that have been investigated in different sheep populations worldwide for its association with prolificacy traits. The present study was performed to validate the association of c.746A>G SNP of BMPR1B

Influencing prolificacy of sows by selection for physiological factors [PDF]

Bioscientifica Proceedings, 2020
The potential to improve prolificacy, with major emphasis on selection for components of litter size, ovulation rate and prenatal survival, and selection for physiological factors are reviewed. Response to selection for physiological factors is superior to direct selection if physiological factors have moderate heritabilities and moderate to high ...

Genome-Wide Identification of a Regulatory Mutation in BMP15 Controlling Prolificacy in Sheep

Frontiers in Genetics, 2020
The search for the genetic determinism of prolificacy variability in sheep has evidenced several major mutations in genes playing a crucial role in the control of ovulation rate.

Prolificacy in small ruminants

Journal of Dairy, Veterinary & Animal Research, 2020
Prolificacy is the ability to reproduce abundantly. Litter size, which is highly dependent on ovulation rate, has a high economic value and it is a fundamental reproductive trait, especially in small ruminants. Considering the low heritability of prolificacy, it is possible to improve the progress of the prolificacy trait selection using DNA markers ...

Investigation of FecB Mutation in Four Romanian Sheep Breeds

Scientific Papers Animal Science and Biotechnologies, 2023
Hyperprolific phenotype of Booroola sheep was first discovered in the Australian Merino breed. This phenotype is due to the action of a single autosomal gene that influences the number of ovulations per estrogenic cycle.

Growth Performance and Survival Rate of Boer X Central Highland Goat under Extensive Production System

Scientific Papers Animal Science and Biotechnologies, 2023
This study was conducted to evaluate the growth performance and survival rate of Boer x Central Highland goats. Data collected under field condition were utilized for this study. The overall least squares mean for birth weight (BWT), weaning weight (3MWT)

Influence of Rearing System on Sows’ Prolificacy during Gestation

Scientific Papers Animal Science and Biotechnologies, 2023
In females reared in individual crates until early control of gestation and in common crates (8-16 heads), prolificacy did not reach values that differ depending on the rearing system: there is a statistically insignificant difference in t-test (p>0.05).

Polymorphisms of the BMPR1B, BMP15 and GDF9 fecundity genes in four Chinese sheep breeds [PDF]

Archives Animal Breeding
Numerous studies on prolific sheep breeds have shown that the transforming growth factor beta (TGF-β) superfamily members, including bone morphogenetic protein receptor type 1B (BMPR1B), bone morphogenetic protein 15 (BMP15) and growth differentiation ...

Analysis of porcine MUC4 gene as a candidate gene for prolificacy QTL on SSC13 in an Iberian × Meishan F2 population [PDF]

, 2011
Background: Reproductive traits, such as prolificacy, are of great interest to the pig industry. Better understanding of their genetic architecture should help to increase the efficiency of pig productivity through the implementation of marker assisted ...
