In this study external fat-tail dimensions (upper, middle and lower width, length, length of gap, depth and upper circumference) and fat-tail weights collected on 724 Lori-Bakhtiari sheep were used to study external fat-tail dimensions and their relationships with fat-tail weights. Sheep were 3 months to 6 years old and slaughtered at the industrial slaughter house of Joneghan in Chaharmohal an...

growth rate of 60 lori-bakhtiari single male lambs were assigned to a completely randomized design with two factors. the factors were tail status (with and without fat tail) and fattening period ( 75,90, 105 days). lambs were alternately docked by the use of rubber rings at the begining of the second day of birth. lambs were weaned at 90±5 days of age and randomly divided into three groups...

The kurtosis coefficient is often regarded as a measure of the tail heaviness of a distribution relative to that of the normal distribution. However, it also measures the peakedness of a distribution, hence there is no agreement on what kurtosis really estimates. Another disadvantage of the kurtosis is that its interpretation and consequently its use is restricted to symmetric distributions. Mo...
