Variabilidad y correlación en la concentración de lípidos sanguíneos en dos líneas genéticas de gallinas ponedoras

This study evaluated and correlated the levels of total cho-lesterol, triglycerides and high density lipoprotein cholesterol in two laying hens lines; taking also into account the egg production, as initial work in the investigation, variability lipid profile in laying hens at different stages of production. Af-ter fasting, serum of 90 laying hens 45 Hy-Line W-36 y 45 Lohmann Brown-Classic of 26 weeks of age was taken. The levels of the total cholesterol, triglycerides and high density lipoprotein cholesterol were determined using the enzymatic-cholorimetric method. Mean ± standard error for total choles-terol, triglycerides and high density lipoprotein cholesterol for Hy-Line W-36 line in mg/dL were: 14.,8±5.49; 773.2±48.06; 13.4±052; respectively, and Lohmann Brown-Classic line in mg/dL were: 111.1±3.58; 431.7±28.74; 16.6±0.4; res-pectively. There were differences (P > 0.05) among lines for levels of total cholesterol, triglycerides and high density lipoprotein cholesterol. Total cholesterol was positively cor-related with triglycerides in two lines, and total cholesterol with the high density lipoprotein cholesterol in the Lohmann Brown-Classic line, with significance (P < 0.05). It was ob-served that Hy-Line W-36 line has higher levels of cholesterol and triglycerides, and the Lohmann Brown-Classic line has more levels of high density lipoprotein cholesterol and higher egg production, which makes it necessary to perform further research to determine how high levels of cholesterol and tri-glycerides within eggs have repercussions, with a decrease in the expected production, and its implication in human health.
