Inbreeding depression on growth and prolificacy traits in two lines of rabbit
(Wiley, 2022-10-26)
Inbreeding depression in closed populations impairs animal fitness, health, and productivity. However, not all inbreeding is expected to be equally damaging. Recent inbreeding is thought to be more ...
Use of Bayes factors to evaluate the effects of host genetics, litter and cage on the rabbit cecal microbiota
(BMC, 2022-06-27)
Background
The rabbit cecum hosts and interacts with a complex microbial ecosystem that contributes to the variation of traits of economic interest. Although the influence of host genetics on microbial ...
Analysis of the causal structure of traits involved in sow lactation feed efficiency
(BMC, 2022-07-26)
Background
Feed efficiency during lactation involves a set of phenotypic traits that form a complex system, with some traits exerting causal effects on the others. Information regarding such ...
Genotype by feeding regimen interactions for slaughter traits in rabbit and expected responses under restricted and full feeding
(Wiley, 2022-05-12)
The interaction between the genotype and feeding regimen (G×FR) for slaughter traits was estimated from data corresponding to 2557 animals under full (FF) and 2424 with restricted feeding (RF). Expected ...
Disentangling the causal relationship between rabbit growth and cecal microbiota through structural equation models
(BMC, 2022-12-19)
Background
The effect of the cecal microbiome on growth of rabbits that were fed under different regimes has been studied previously. However, the term “effect” carries a causal meaning that can be ...
Milk fat globule membrane plus milk fat increase docosahexaenoic acid availability in infant formulas
(Springer, 2022-10-25)
Purpose
Milk fat globule membrane (MFGM) has components with emulsifier properties that could affect the provision of substrates to the brain. We evaluated the effects of MFGM plus milk fat addition ...
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) ...
Longitudinal modelling of performance and feed efficiency traits in growing Duroc pigs
(Elsevier, 2022-01-07)
In this study we used the phenotypic information of 1,499 Duroc pigs, recorded longitudinally in the age period from 110 to 200 days of age for individual daily feed intake (DFI), backfat thickness (BF) ...
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 ...
Parámetros genéticos de rasgos productivos de cuyes (Cavia porcellus) de las líneas Saños y Mantaro
(Universidad Nacional Mayor de San Marcos, 2022-06-29)
El objetivo del estudio fue estimar los componentes de varianzas, la heredabilidad y correlaciones genéticas y fenotípicas de los rasgos productivos de las líneas de cuyes Saños y Mantaro, desarrolladas ...
