Beefcarcasses: Cattle Carcasses in Norwegian Slaughterhouses

Description

The data in this data set is real data from cattle carcasses in Norwegian Slaughterhouses. In addition to the KFactor, breed, gender and age of the cattle when slaughtered are registered for all carcasses.

Usage

Beefcarcasses

Format

A data frame with 72 observations (rows) and 4 variables (columns).

	Column name	Data type	Description	Values
[,1]	KFactor	numeric	The Kfactor for each carcass	(1.905 - 5.150)
[,2]	Breed	Character	3 cattle breeds	("Limousin", "NRF", "Holstein")
[,3]	Gender	Character	2 genders; Bull = male, Cow = female	("Bull", "Cow")
[,4]	Age	numeric	The age of the cattle in days	(305 - 722)

Details

The three cattle breeds:

• Holstein: a breed specialized on dairy (milk) production

• Limousin: a breed specialized for beef production

• NRF: (Norwegian Red Cattle) is a so-called combination breed, i.e., bred for both dairy and beef production

Carcasses are classified in accordance with the EUROP standard, where confirmation (i.e., the overall form of the carcass) and fat content are graded at 15-point scale(s). The confirmation class correlates well to the so called KFactor:

KFactor = {10}^5 \frac{Weight(kg)}{{Length}^3({cm}^3)}

This data was used in the compulsory assignment in STAT210 H19, and in Exercises for STAT210 (exercise 14) in August 2022.
