Publisher: 2010Dissertation note: The present study was conducted at Livestock Experiment Station Khizrabad (Sargodha). Khizrabad is a small town of tehsil Bhalwal district Sargodha. The objective of the study was to fing out or develop the relationship between live body weight and body measurements in Kajli sheep. The sheep were arranged in nine age groups, A 0-3, B 4-6, C 7-9, D10-12, E= 13-15, F16-18, G 19-21, H 22-24 and 1 above 24 months. Group A, B, C, and D were further divided into sub groups (Male & Female), where as the groups E, F, G, H and I comprised of Ewes only. Body weights were taken using digital weighing scale and measurements of body height at wither, body length, heart girth, head length, head width, rump length and rump width with the help of measuring tape graduated with inches. Data on 788 female! 120 male and total of 908 observations of different age groups of sheep were collected. The mean height at wither (Inches) of Kajli sheep in nine age groups (0-3, 4-6, 7-9, 10-12, 13-15, 16-18, 19-21, 22-24 and above 24 months of age) was found to be 19.34 ± 1.36 (Overall), 19.33 ± 1.33 (female), 19.52 ± 1.26 (male), 20.42 ± 1.04 (Overall), 20.54 ± 1.01 (female), 20.25 ± 1.11 (male), 21.59 ± 0.90 (Overall), 21.84 ± 0.97 (female), 21.38 ± 0.78 (male), 23.55 ± 1.00 (Overall), 23.76 ± 0.84 (female), 22.58 ± 1.14 (male), 27.34 ± 1.25, 28.57 ± 0.92, 28.49 ± 1.39, 29.30 ± 1.01 and 29.57 ±1.30.

It was found during the study that body weight was highly correlated with body measurements in Kajli sheep of all age groups. The height at wither, body length and heart girth were observed to be significantly correlated with body weight. During the present investigation males were heavier and longer than females in all age groups. Similarly the heart girth as well as height at wither were also bigger in males than those of females.
Conclusion:
It was concluded that body measurements had high correlation with body weight indicating that body measurements can be used for estimation of body weight in the field where scales are not usually available. These may also be used as selection criteria. However, further research is needed to investigate the relationship between the body weight and linear body measurements in other breeds of sheep, goats and other livestock breeds of the country.

Publisher: 2011Dissertation note: The present study was conducted at Livestock Production Research Institute, Bahadurnagar, Okara. The objective of the study was to find out or develop the relationship between live body weight and body measurements in Lohi sheep breed. The sheep were arranged in five age groups, groups A, B, C, D, and E. The group A was comprised of 0-6 month of age; group B= 7-12, group; C= 13-18, group D= 19-24 and group E above 24 months age of animals. Group A, B and E were further divided into sub groups (Male & Female), where as the groups C and D comprised of Ewes only. Body weights were taken using weighing scale and measurements of Body weight, Height at Wither, Body Length, Heart Girth, Head Length, Head Width, Ear Length, Ear Width, Neck Length, Neck Width, Rump Length, Rump Width, Barrel Depth, Sacral pelvic Width, Teat Length, Teat Diameter, Testes Length and Testes Circumference with the help of measuring tape graduated with centimeter. Data on 1008 female / 44 male and total of 1052 observations of different age groups of sheep were collected. The mean of all body measurements (cm) and body weight (kg) of Overall Lohi sheep of age group 0-6, was found to be 46.03 ± 11.00 (cm), 45.41 ± 10.24 (cm), 43.79 ± 9.47(cm), 14.75 ± 4.32 (cm), 6.62 ± 1.20 (cm), 23.22 ± 4.73 (cm), 9.46 ± 3.08 (cm), 15.69 ± 5.45 (cm), 10.51 ± 3.56 (cm), 14.83 ± 5.41 (cm), 8.68 ± 2.63 (cm), 26.77 ± 8.15 (cm) and 7.80 ± 4.77 (Kg) respectively.
