Body mass index, energy reserves, and tissue composition of cuts of Corriedale lambs

Abstract

The objective of this work was to identify relationships of the body mass index (BMI) with the body energy reserves and tissue composition of shoulder and leg cuts of Corriedale lambs. Twenty-two sheep with average age of 18 months were used. Linear regressions were determined between the studied characteristics. The mean body mass, body condition score (BCS), and BMI were 49.09±7.8 kg, 2.69±0.81, and 10.66±0.99, respectively. The BMI was correlated with the BCS (r = 0.51) and internal fat (r = 0.81). Multiple linear equations, involving BMI and BCS, yielded correlation coefficients between 0.50 and 0.76, with significant values for all studied characteristics. The body mass index allows estimating the body energy reserves of Corriedale sheep.

Body mass index at calving on performance and efficiency of Zebu cow herds

“…Body mass index was calculated by dividing the cow's body weight at calving (CBW) by its hip height (HH) and by its length (L) and subsequently dividing the result by 10 (Costa et al, 2020), according to the following formula: BMI = (CBW/HH/L) /10 Cow length was measured using a tape measure, between the scapulohumeral and coxofemoral joints. Hip height was determined using a set square, which measured the distance between the upper part of the sacrum and the soil surface.…”
