Genetic parameters and expected responses to selection for components of feed efficiency in a Duroc pig line
(BMC, 2017-12-01)
Background: Improving feed efciency (FE) is a key factor for any pig breeding company. Although this can be achieved by selection on an index of multi-trait best linear unbiased prediction of breeding ...
The effect of a high monounsaturated fat diet on body weight, backfat and loin muscle growth in high and medium-lean pig genotypes
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2012-01-23)
The objective of this study was to evaluate whether the use of a diet rich in oleic acid could have an effect on daily
weight gain, backfat and loin muscle (Longissimus thoracis) depth. One hundred and ...
Detection of homozygous genotypes for a putatively lethal recessive mutation in the porcine argininosuccinate synthase 1 (ASS1) gene
(Wiley, 2019-11-15)
The sequencing of the pig genome revealed the existence of homozygous individuals for a nonsense mutation in the argininosuccinate synthase 1 (ASS1) gene (rs81212146, c.944T>A, L315X). Paradoxically, ...
Interaction of direct and social genetic effects with feeding regime in growing rabbits
(BMC, 2017-07-20)
Background: Most rabbit production farms apply feed restriction at fattening because of its protective efect against digestive diseases that afect growing rabbits. However, it leads to competitive ...
Second litter syndrome in Iberian pig breed: factors influencing the performance
(Elsevier, 2022-11-09)
Second litter syndrome (SLS) consists of a loss of prolificacy in the second parity (P2), when a sow presents the same or lower results for litter size than in the first parity (P1). This syndrome has ...
Genomic differentiation among varieties of Iberian pig
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2020-02-26)
Aim of study: The objective of this study was to identify the autosomal genomic regions associated with genetic differentiation between three commercial strains of Iberian pig.
Area of study: Extremadura ...
Admixture and breed traceability in European indigenous pig breeds and wild boar using genome-wide SNP data
(Nature Research, 2022-05-05)
Preserving diversity of indigenous pig (Sus scrofa) breeds is a key factor to (i) sustain the pork chain (both at local and global scales) including the production of high-quality branded products, (ii) ...
Social network analysis of agonistic behaviour and its association with economically important traits in pigs
(MDPI, 2020-11-16)
Aggression behaviour has several negative consequences on the performance and welfare of pigs. Here, the Social Network Analysis (SNA) approach was employed to (1) identify individual traits that describe ...
Functional longevity in five rabbit lines founded on different criteria: Comparison at foundation and at fixed times after selection
(Wiley, 2021-03-08)
The enhancement of rabbit female functional longevity, that is the ability to avoid voluntary culling, is a paramount aspect for the sustainability of meat rabbit production; this trait represents a ...
Novel phenotypes of feeding and social behaviour and their relationship with individual rabbit growth and feed efficiency
(Elsevier, 2024-01-30)
Due to the lack of a recording system for individual consumption of group-housed rabbits, published studies about feeding behaviour are based on information recorded at the group- and not at the individual ...
