Estimates of (co) variance components and genetic parameters were calculated for birth
weight (BWT), weaning weight (WWT), 6month weight (6WT), 9month weight (9WT),
12month weight (12WT) and greasy fleece weight at first clip (GFW) for Malpura sheep. Data
were collected over a period of 23years (1985–2007) for economic traits of Malpura sheep
maintained at the Central Sheep & Wool Research Institute, Avikanagar, Rajasthan, India.
Analyses were carried out by restricted maximum likelihood procedures (REML), fitting six …

(Co) variance components and genetic parameters of weight at birth (BWT), weaning (3WT),
6, 9 and 12 months of age (6WT, 9WT and 12WT, respectively) and first greasy fleece weight
(GFW) of Bharat Merino sheep, maintained at Central Sheep and Wool Research Institute,
Avikanagar, Rajasthan, India, were estimated by restricted maximum likelihood, fitting six
animal models with various combinations of direct and maternal effects. Data were collected
over a period of 10 years (1998 to 2007). A log-likelihood ratio test was used to select the …
