Efecto De Una Sal Nitrogenada En Novillos En Fase De Ceba En Yopal Casanare, Angélica Yorleth Amézquita Guzmán
Zootecnia
Este estudio se realizó para determinar el efecto de la sal nitrogenada en novillos en fase de ceba en Yopal, Casanare. Se plantearon dos tratamientos, T1: Sal nitrogenada y T2: Sal mineralizada, cada uno contó con 10 machos cebú comercial con peso promedio de 400 kg y edad promedio de 36 meses. El experimento se realizó en época seca, durante un tiempo de tres meses. Se evaluó el peso corporal y la ganancia de peso. Aunque no se encontraron diferencias significativas de ganancia de peso entre los promedios de los tratamientos, la sal nitrogenada incrementó en promedio 6 kg por …

Development And Validation Of Gas Chromatographic Methods For Free Fatty Acid Determination In Dairy Products, David Mannion
Theses
Quantification of free fatty acids (FFA) in dairy products by gas chromatography flame ion'^ation detection is an important requirement for qua'ity, research, nutritional, authenticity and legislative purposes. Common procedures are typically variants of either the fatty acid methyl esterification (FAME) or direct on-column injection methods developed more than two decades ago. This study involved the development of an alternative novel derivatization method using butylation, incorporating automation, reducing solvent usage that is applicable for a wide range of dairy products. The accuracy, precision, linearity, limits of detection and limits of quantification of all three methods were assessed for the quantification of …
