Le poids de l’épiploon (rapporté au DNA) de 5 chèvres en 9e semaine de lactation est en relation inverse avec la quantité de lait produite au cours des 2 premiers mois de lactation. Cette relation semble résulter d'un dépôt de lipides dans le tissu adipeux, d’autant plus précoce que les animaux prod...

Nutritional regulation of the expression of genes involved in lipogenesis in ewes fed sunflower oil. 2. Subcutaneous and perirenal adipose tissues

Colloques et conférences

Pablo Gutierrez Toral et al. (14 mai 2013)

Colloques et conférences

This study was conducted to compare the potential implication of the subcutaneous and perirenal adipose tissues (AT) in the response of lipid metabolism of lactating ewes to sunflower oil, a dietary supplement known to induce changes in milk fatty acid (FA) composition. Ten sheep (5 animals/treatmen...

Nutritional regulation of the expression of genes involved in lipogenesis in ewes fed sunflower oil. 1. Mammary secretory tissue

Colloques et conférences

Pablo Gutierrez Toral et al. (14 mai 2013)

Colloques et conférences

A study was conducted in ewes consuming sunflower oil to investigate the response of the mammary secretory tissue, in terms of mRNA abundance of genes involved in lipogenesis, to a diet known to induce changes in milk fatty acid (FA) composition. Ten sheep (5 animals/treatment) received a total mixe...

Nutritional regulation of mammary lipogenesis and milk fat in ruminant: contribution to sustainable milk production

Articles

Laurence Bernard et al. (2013)

Articles

Researches in animal science focus on contributing to the development of sustainable livestock production systems in agreement with societal expectations. In particular, researches in dairy sciences aimed to improve the understanding of the biology of herbivores and developed strategies to modulate...

Maîtrise par l'alimentation des teneurs en acides gras et en composés vitaminiques du lait de vache

Articles

Anne Ferlay et al. (2013)

Articles

Après un rappel de l’origine digestive et métabolique des acides gras et des composés vitaminiques du lait, cet article relate l’effet des principaux facteurs alimentaires sur leur concentration. L’herbe pâturée, par rapport à des rations hivernales, diminue les teneurs du lait en acides gras saturé...

Plasma leptin, glucose and non-esterified fatty acid variations in dromedary camels exposed to prolonged periods of underfeeding or dehydration

Articles

Carole Delavaud et al. (2013)

Articles

The involvement of plasma leptin in the adaptation of dromedary camels to harsh conditions such as food or water shortages was studied through 2 experiments. In experiment 1, fourteen female camels were either fed at 68% of maintenance energy requirements (MER) during 112d (n=4) or overfed at 134% o...

Effects of fish oil and additional starch on tissue fatty acid profile and lipogenic gene mRNA abundance in lactating goats fed a diet containing sunflower-seed oil

Articles

Pablo Gutierrez Toral et al. (2013)

Articles

In dairy cattle, diet supplementation with oils affects the lipid metabolism in body tissues via changes in the partitioning and deposition of fatty acids (FAs) and lipogenic gene expression; however, limited data are available in goats. Eight Alpine goats were fed a grassland hay diet supplemented...

Effects of incremental amounts of extruded linseed on the milk fatty acid composition of dairy cows receiving hay or corn silage

Articles

Anne Ferlay et al. (2013)

Articles

The effect of supplementation of increasing amounts of extruded linseed in diets based on hay (H; experiment 1) or corn silage (CS; experiment 2) was investigated in regard to dairy performance and the milk fatty acid (FA) composition. In each experiment, 4 lactating multiparous Holstein cows were u...

Prediction of bulk milk fatty acid composition based on farming practices collected through on-farm surveys

Articles

Mauro Coppa et al. (2013)

Articles

The aim of this study was to predict the fatty acid (FA) composition of bulk milk using data describing farming practices collected via on-farm surveys. The FA composition of 1,248 bulk cow milk samples and the related farming practices were collected from 20 experiments led in 10 different European...

Prediction of the goat milk fatty acids by near infrared reflectance spectroscopy

Articles

Donato Andueza et al. (2013)

Articles

Near infrared reflectance spectroscopy (NIRS) was used to predict the goat milk fatty acid (FA) profile. The ability of cow milk broad-based calibration equations to predict the goat milk FA profile was assessed. Three hundred twenty-eight samples in the calibration set and 108 in the validation set...
