Relationships between body mass index, ultrasound measurements and, internal body fat depots in pelibuey sheep

The objective of this study was to evaluate the relationship between body mass index (BMI), ultrasound measurements (USM), and internal fat (IF) in hair sheep. BMI USM were determined 24 hours before laughter 35 animals finished intensive fattening. At slaughter, IF (inner adipose tissue) dissected, weighed, grouped as mesenteric, omental, or perirenal fat; these three depots summed obtain their total weight. variables evaluated through Pearson's correlation coefficient (r) using CORR procedure by regression models REG SAS ver. 9.3. presented r= 0.75 (P <.0001), while an r that varied from 0.70 0.80 <.0001). Among deposits, one minor coefficients with (r = 0.55), subcutaneous thickness (0.55), thoracic Longissimus dorsi area) 0.33), for this, last not significant (P>0.05). equation had a determination (r2) 0.67 inclusion together improved r2 range 0.77. could be used predict weight
