Conference Paper 1992

Autor: Inyangala, B.A.O. Rege, J.E.O. Itulya, S.

Presents results of a study undertaken at Magogo, Kenya, to analyse genetic and phenotypic correlations between adjacent weights, between weights and rates of growth, and among growth rates themselves, hence data on 969 lambs collected over a 10-year period (1978-1987) on Dorper sheep were used i...

This study was undertaken to investigate the relationship between date of birth and growth performance of calves born to seasonally-bred range cows. Late born calves exhibited an apparent superiority in preweaning growth over that of their early-born counterparts. This was attributed to a positiv...

The pattern of growth and carcass composition of indigenous Ethiopian fat tailed Menz and Horro lambs were assessed through serial slaughter and carcass dissection of 147 lambs at five different growth phases. The GLM procedure of Statistical Analysis Systems Institute and allometric growth equat...

Body weight (LW), condition score (BCS), tail length on inner side of tail (TL), tail volume measured by water displacement (TV) and tail circumference (TC), width (TW) as well as thickness at the base (TT) were measured in live Menz (n=303) and Horro (n=151) sheep to determine their possible use...

Presents results of a study carried out to analyse growth traits of the Dorper sheep. Data on 969 lambs collected over a 10-year period (1978 to 1987) at Magogo, Kenya were used in the study. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages...

Factors affecting the early growth and survival of indigenous Ethiopian Horro sheep were identified and the influence of each was assessed, based on data collected from 1978 97 from 4031 lambs at Bako Research Centre, Ethiopia. Year of birth, sex, type of birth or rearing, and parity had signific...

Variance components and genetic parameters were estimated for growth traits: birth weight (BWT), weaning weight (WWT), 6-month weight (6MWT) and yearling weight (YWT) in indigenous Ethiopian Horro sheep using the average information REML (AIREML). Four different models: sire model (Model 1), dire...

Data on 969 lambs collected over a 10-year period (1978 to 1987) on Dorper sheep at Ol'Magogo were used in this study. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages of growth. Heritability estimates from paternal half-sib analysis were: ...

Data on 969 Dorper lambs collected over a 10-year period (1978 to 1987) at Ol'Magogo were used in this study. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages of growth. All the fixed effects studied influenced growth in one way or another....

A selection programme (PNSO) was set up in 1983 in Cote d'Ivoire to increase growth and liveweight of the indigenous Djallonke sheep, using open nucleus breeding system. Selection was based on male individual weight at 80, 180 and 365 days of age. 10,417 records on 80 day weights (WT80) of lambs ...
