BIOLOGICAL VALUE OF SHEEP MILK BASED ON THE TYPE OF FOOD
Abstract
In this research study we have analyzed the quality of sheep's milk depending on the food. It has been taken into consideration the milk provided by pasture-fed sheep and hill fertilized lowland pasture, soil podzolic. The breed of sheep is Turcan. There have been studied the chemical characteristics of milk and, and, in order to establish the compared biological value between the two alternatives, milk’fat acids composition has been analyzed. Fat acid’concentration has been performed by means of gas chromatography. There have been determined 19 saturated, monounsaturated and polyunsaturated fat acids. Due to the importance of the essential fat acids, it has been particularily studied their evolution, being obtained the following values Milk provided by sheep fed on unfertilized pasture hill: linoleic acid (ω6); acdlinoleic (ω3) γlinolenic acid (ω6), while the milk provided by sheep fed on lowland pasture: linoleic acid (ω6) -1.85; linolenic acid (ω3) -0.98 γlinolenic acid (ω6) -1.63 and lowland pasture, podzolic soil: acid linoleic (ω6) -2.29; linolenic acid (ω3) -1.19 γlinolenic acid (ω6) -1.25.The papers published in the journal are licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License, which permits unrestricted, non-commercial use, distribution and reproduction in any medium, provided the work is properly cited.
