A Comparison of Damara Crossbred and Merino Lambs Wool
Lambs wool production and qualities from the progeny of 2 Merino and 2 Damara rams mated to Merino ewes were compared. The crossbred lambs produced about half the amount of wool and had high fibre diameter variation and medullated fibre components. Merino lambs wool was contaminated with pigmented and medullated fibres apparently transferred from continual exposure to the Damara crossbred lambs...
متن کاملRetardation of wool growth in Merino sheep caused by bacteria.
A condition evidenced by retarded growth of wool with alteration of the yolk into a yellow, sticky, wax-like substance was investigated. The condition was associated with hyperaemia and cellular infiltration into the dermis in the affected areas. Three bacterial species, viz. Enterobacter aerogenes, E. agglomerans and Hafnia alvei, which could grow on the water-extractable component of wool-yol...
متن کاملGenetic Parameters in Merino Sheep GENETIC RELATIONSHIPS BETWEEN CARCASS QUALITY AND WOOL PRODUCTION TRAITS IN AUSTRALIAN MERINO RAMS
The heritability of carcass quality traits and the genetic correlations between wool production and these carcass quality traits were estimated on 1216 Merino rams. The results showed that carcass quality traits are moderately heritable but pH appears to be lowly heritable. Yellowness and redness of L. dorsi had very low heritability estimate. Moderate negative genetic relationships were found ...
متن کاملThe Chemical & Physical Structure of Merino Wool
Figure 2: Formation of a polypeptide by reaction of amino acids. (R , R and R may be the same or different 1 2 3 side groups). These contaminants are removed during processing. Clean wool, together with other animal fibres, belongs to a group of proteins known as keratins. Unlike cotton and the majority of synthetic fibres, wool does not have a homogeneous structure. Wool fibres have highly com...
