1.
18 Months Weight (kg)
(
2
)
Live body weight of the animal at the age of 18 months
2.
Adult Body Length (cm)
(
4
)
The horizontal distance (in centimetres) from the point of shoulder to the pin bone (Ayalew, 1992).
3.
Adult Heart Girth (cm)
(
4
)
The circumference of the body (in centimeters) immediately behind the shoulder blades in a vertical plane, perpendicular to the long axis of the body (Ayalew, 1992).
4.
Adult Live Weight (kg)
(
5
)
The fasted live body weight (in kilogrammes) of adult animals (Ayalew, 1992).
5.
Adult Wither Height (cm)
(
4
)
Adult wither height is the height of an adult animal (in centimeters) from the bottom of the front foot to the highest point of the shoulder between the withers. Withers is the top of the shoulders (Bath et al. 1985; Ayalew, 1992).
6.
Age at First Parturition (months)
(
2
)
Age in months at first parturition of a female animal, i.e. the time when the animal gives birth to its first off-spring. It marks the beginning of an animal's productive life and often closely relates to generation interval and, therefore, influences response to selection (Mukasa-Mugerwa, 1989).
7.
Carcass Weight (kg)
(
1
)
Carcass weight is measured on the carcass which remains once the animal has been bled, its head removed at the atlas joint, the forefeet severed at the knee joint between the carpal and metacarpal bones, the hindfeet severed at the hock joint between the tarsal and metatarsals, the body eviscerated, the hide or skin removed and the tail cut off close to the junction of the sacral and caudal vertebrae. Evisceration is the removal of the contents (viscera) of the thoracic (chest) and abdominal cavities, to which must be added the throat (oesophagus), windpipe (trachea) and the external genital organs and mammary glands (udders) (Payne, 1990).
8.
Dressing Percentage (%)
(
1
)
Dressing out percentage is a proportion in per cent of the carcass to the animal's liveweight, specifying whether or not the slaughter weight was fasted, and whether the carcass was hot or cold during measurement (Payne, 1990).
9.
Horn Length (cm)
(
1
)
The length of the horn (in centimetres) on its exterior side from its root at the poll to the tip (Ayalew, 1992).
10.
Hump
(
1
)
Description of the shape, orientation, folding, size and any peculier feature of the hump.
11.
Parturition Interval (days)
(
2
)
The interval, in days, for an individual female from one parturition to the next (Esslemont et al., 1985).
12.
Parturition Percentage (%)
(
1
)
The number of services given to a defined group of cows or heifers or over a specified period which result in a parturition (calving), expressed as a percentage of the total number of services (Esslemont et al., 1985).
13.
Productivity Index
(
2
)
Productivity index incorporates calf bodyweight at 6, 9 or 12 months and the body weight equivalent of milk produced. As used by Trail and Gregory (1981), measures of reproductive performance, cow and calf viability, milk yield, growth and cow weight are combined to derive the cow productivity index (kg) per cow per year or per 100 kg liveweight of cow of breeding age maintained annually. It is computed as: (cow viability (%) x calving percentage x calf viability (%) x calf weight at 6, 9 or 12 months or at weaning (kg)) + (cow viability (%) x calving percentage x lactation milked-out yield (kg))/9 (Mukasa-Mugerwa, 1989).
14.
Slaughter Weight (kg)
(
1
)
Live body weight of the animal at the event of slaughter, with specification of whether or not the animal was fasted or fed before slaughter.
15.
Weight at Specific Age (kg)
(
4
)
16.
Yearling Weight (kg)
(
2
)
Live body weight (in kilograms) of the animal at the age of one year (365days).
