Effect of grazing cows in an intensive silvopastoral system with Leucaena leucocephala on Panela cheese properties: yield, composition, fatty acid profile and sensory acceptability.

Abstract

Yield, chemical composition, fatty acid profile, and sensory acceptability of Panela cheese produced from cows grazing in an intensive silvopastoral system (ISS) with Leucaena leucocephala and Cynodon nlemfuensis were evaluated and compared with Panela cheese from cows grazing a monoculture system (MS) of C.nlemfuensis only. The experiment lasted for 9weeks in a tropical area in Mexico using ten crossbred cows (30-90days of milking) assigned homogenously as five cows in each experimental group. No significant differences were found between the two systems for milk and cheese gross composition. Panela cheese from ISS showed lower content of the hypercholesterolemic fatty acids, accompanied with higher content of omega-3, omega-6 and polyunsaturated fatty acids. In addition, Panela cheese from ISS showed higher preference for the attributes of appearance, texture, flavor, and overall acceptability. It is concluded that Panela cheese from cows grazing in ISS has better acceptability and nutritional properties than that produced from MS with grass only.
