OSORIO, J. H; BARRERA, L. M  e  PEREZ, J. E. COMPARISON OF LIPID PROFILE BY SEX AND AGE IN SHEEPS. Rev. Med. Vet. Zoot. [online]. 2015, vol.62, n.1, pp.11-19. ISSN 0120-2952.  https://doi.org/10.15446/rfmvz.v62n1.49381.

To objective was to compare the lipid profile in sheep and to analyze the relationship between serum lipids levels of four groups. Blood samples from 98 sheep were obtained in fasting state, differentiated by gender and age (23 males and 25 female aged over 12 months; 22 males and 28 females aged under 12 months). Serum concentrations of total cholesterol (TC), triglycerides and high density lipoprotein cholesterol (HDL-C) were measured using enzymatic colorimetric method; levels of very low-density lipoprotein cholesterol (VLDL-C) and low-density lipoprotein cholesterol (LDL-C) were determined using Friedewald equation. Mean for TC, triglycerides, HDL-C, VLDL-C and LDL-C were: 86.19, 21.57, 39.32, 4.31, 42.55 mg/dL respectively. The group of adults was differ (P < 0.05) for TC (P <0.0003), HDL-C (P <0.0007) and LDL-C (P <0.0133), being increased in females. In young females HDL-C was higher (49.02 mg/ dL). In males significant differences were observed in TC (P <0.0138), and LDL-C (P <0.0006) and females in TC (P <0.015). Triglycerides and VLDL-C in females (P >0.90 for both), in males (P <0.405 for both), in young (P >0.487 for both) and adults (P >0.179 for both) showed no significant differences (P-value >0.05) with a confidence level of 95.0%. In Conclusion given the differences in the comparisons between groups for the lipid profile in sheep, can be considered four lipid profiles as follows: adult males, adult females, young males and young females.
