Impact of diet on diaphragm lipid composition from bovine females of various ages

<p dir="ltr">It is commonly reported that, compared to animals fattened with higher concentrate diets, the meat of animals raised on pasture is significantly leaner and richer in n-3 and antioxidants, while containing lower levels of n-6 fatty acids. This profile contributes to the superior nutritional properties and health value of meat from pasture-fed animals, including an n-6/n-3 ratio that aligns more closely with ANSES recommendations. In a context where it is becoming necessary to reflect collectively on the design of animal husbandry methods that mitigate their negative impacts and further develop positive externalities and services, this study aimed to evaluate the nutritional properties of meat from animals reared extensively on grassland farms compared with more intensive feeding systems. </p><p dir="ltr">Two questions arise: are the nutritional properties equivalent regardless of 1/ the main forage in the finishing diet (grazed or established meadow hay)? and 2/ the quantities and nature of the concentrates added to the ration?</p>
