Characterisation of Zulu (Nguni) sheep using linear body measurements and some environmental factors affecting these measurements

Data on linear body measurements (LBM) of ca. 100 Zulu sheep raised under extensive management systems at four sites in northern KwaZulu-Natal were collected over a period of 2.5 years (October 2000 to May 2003). Data were used to quantify the live weight (LW), heart girth (HG), wither height (WH) and scrotum circumference (SC) of sheep in different age groups as well as the effects of some env...

The Estimation of Body Weight from Body Measurements in Kilakarsal Sheep of Tamil Nadu, India

Data on body weight and body measurements (body length, height at withers, chest girth and paunch girth) of adult Kilakarsal sheep have been collected from 124 adult animals managed at the farmers filed in Tirunelveli districts of Tami Nadu, India to estimate the body weight from body measurements. The data were subjected to standard statistical analysis using SPSS software and linear regressio...

Heritability parameters for some body measurements in Turkish Arabian foals

The aim of the present study was to estimate genetic parameters of body measurements in TurkishArabian foals. Records of wither height, front cannon circumference, heart girth, and body length were usedfor body measurements at birth, 6 months of age, 1-year-old and 2-year-old. Heritability of bodymeasurements of Turkish Arabian foals was estimated by using records of foals sired by stallions wh...

Study of Factors Affecting Longevity and Survival of Iranian Guilan Sheep Using Linear and Non-Linear Models

The objective of this study was to evaluate non-genetic factors affecting longevity and survival of Guilan sheep from birth to yearling. Longevity and survival records of 41037 lambs born from 496 rams and 10256 ewes of Guilan sheep were analyzed using linear and Weibull models. Results indicated that the overall mean of longevity was 1260.84 days. The fixed effects of flock, dam age, sex, year...
