Adipose tissue modification through feeding strategies and their implication on adipogenesis and adipose tissue metabolism in ruminants
Dietary recommendations by health authorities have been advising of the importance of diminishing saturated fatty acids (SFA) consumption and replacing them by polyunsaturated fatty acids (PUFA), particularly omega-3. ... -
Conversión de las explotaciones de vacuno de leche a la producción de leche A2 ante una posible demanda del mercado: posibilidades e implicaciones
El mercado de la leche de vaca, tras la desaparición de las cuotas lácteas, está provocando una importante restructuración en el sector. Una de las alternativas que están desarrollando, fundamentalmente las pequeñas ... -
Detection of minced lamb and beef fraud using NIR spectroscopy
The aim of this work was to investigate the feasibility of near-infrared spectroscopy (NIRS), combined with chemometric techniques, to detect fraud in minced lamb and beef mixed with other types of meats. For this, 40 ... -
Development of a duplex qPCR assay with locked nucleic acid probes for A, B and E kappa-casein variants detection
Milk proteins determine important milk technological characteristics. Among caseins, Ƙ-casein has been correlated with fat and protein content and cheese yield. Fourteen Ƙ-caseins variants have been described but the alleles ... -
Efecto de la utilización de pienso enriquecido en ácidos grasos poliinsaturados en corderos en crecimiento sobre el desarrollo, la composición de la grasa de la carne y la expresión de los principales genes lipógenos del tejido adiposo
En los últimos años, el aporte de ácidos grasos poliinsaturados (PUFA) de tipo n-3 en la alimentación animal es una vía que está siendo estudiada para mejorar el perfil lipídico de la carne, debido a que es un alimento ... -
Effects of addition of linseed and marine algae to the diet on adipose tissue development, fatty acid profile, lipogenic gene expression, and meat quality in lambs
This study examined the effect of linseed and algae on growth and carcass parameters, adipocyte cellularity, fatty acid profile and meat quality and gene expression in subcutaneous and intramuscular adipose tissues (AT) ... -
Expression of key myogenic, fibrogenic and adipogenic genes in Longissimus thoracis and masseter muscles in cattle
Adipogenesis, myogenesis and fibrogenesis are related processes that can contribute to meat quality. Therefore, extending the knowledge of these processes would facilitate the identification of molecular markers that predict ... -
Improving the short‑term efficiency of rock phosphate‑based fertilizers in pastures by using edaphic biostimulants
Background: The use of reactive rock phosphate (RP) in acidic soils as a phosphate (P) source for pastures and crops presents attractive economic advantages with respect to soluble phosphate. However, some studies have ... -
Insights into the role of major bioactive dietary nutrients in lamb meat quality: a review
Feed supplementation with α-linolenic acid (ALA) and linoleic acid (LA) increases their content in muscle, ALA increases n-3 polyunsaturated fatty acids and decrease n-6/n-3 ratio in muscle, and LA increases rumenic acid. ... -
Predicting beef carcass fatness using an image analysis system
The amount and distribution of subcutaneous fat is an important factor affecting beef carcass quality. The degree of fatness is determined by visual assessments scored on a scale of five fatness levels (the SEUROP system). ... -
Volatile compounds, odour and flavour attributes of lamb meat from the navarra breed as affected by ageing
This study aimed to assess the influence of ageing on the volatile compounds, as well as odour and flavour attributes of lamb meat from the Navarra breed. Twenty-one male lambs were fed a commercial concentrate diet after ... -
Worldwide research trends on milk containing only A2 β-casein: a bibliometric study
The protein fraction of β-casein may play a key role in the manifestation of a new intolerance: milk protein intolerance. The most common forms of β-casein among dairy cattle breeds are A1 and A2 β-casein. During ...
