Automated Calculation of Heart Girth Measurement in Pigs Using Body Surface Point Clouds
Computers and Electronics in Agriculture, 2019As increasing number of studies for body measurement purposes in both the animal breeding and production stages, several papers have already evaluated the feasibility of consumer depth sensors for linear body measurement of livestock including pigs and ...

Measurement of heart-girth (chest circumference) is commonly used to estimate dairy heifer body weight from previously derived equations or tables. In this experiment, variability of heart-girth measurements as they are taken in the field was analyzed to determine the standard deviation within a group of 26 Holstein heifers of various ages weighing 42 ...

Use of Heart Girth to Predict Body Weight of Working Oxen in the Ethiopian Highlands
Livestock Science, 2001 Few studies have been conducted in sub-Saharan Africa where multiple recordings of heart girth and body weight were made for the same cattle population. In this study, monthly measurements were taken of working oxen on 24 smallholder farms in the Ethiopian highlands for 1 year.

Prediction of Body Weight With Heart Girth in Small Ruminants in the Semi Arid Maiduguri, Nigeria
International Journal of Natural and Applied Sciences, 2010 Heart girth (HGT) and body weight (BWT) records of 450 goats and 449 sheep were analyzed to determine the predictive value of HGT for BWT in both species as well as the effect of sex and season on HGT. The overall means of heart girth for the two species were 59.51 cm (goats) and 67.58 cm (sheep).

Models to predict live weight from heart girth in crossbred beef heifers
Tropical Animal Health and Production, 2022The objective of this study was to develop and evaluate linear, quadratic, and exponential mathematical models to predict live weight (LW) from heart girth (HG) in crossbred heifers raised in tropical humid conditions in Mexico. Live weight (363.32 ± 150.88 kg) and HG (166.83 ± 24.88 cm) were measured in 400 heifers aged between 3 and 24 months. Linear

Relationships between body weight, condition score and heart girth changes in boran cattle
Tropical Animal Health and Production, 1987 Body weight, heart girth and condition score were monitored in 75 Boran cows over an eight-month period. Condition score was highly correlated with both weight and heart girth when these variables were measured at the end of the dry season. Over the whole period the correlation coefficient between weight and condition score was r = 0.76 and the ...
