Aj. Litherland et al., LENGTH AS A PREDICTOR OF DOWN WEIGHT RANK IN NEW-ZEALAND GOATS, New Zealand Journal of Agricultural Research, 38(3), 1995, pp. 361-365
Down length collected from 1466 and 334 shearings of cashmere and cash
gora goats respectively, was used to predict down weight. Down length
rank explained 34 and 55% of the variation in down weight rank in cash
mere and cashgora goats respectively. In cashmere goats, the relations
hip between down length and down weight was similar in different flock
s, sexes, and years. For each centimetre of down length, down weight w
as lower in yearling and 6-year-old cashmere does compared to mixed-ag
e does. Goats with a finer down and lower down yield, by weight, also
had lower down weights for each centimetre of down length. In cashgora
goats, bucks and does with a higher proportion of Angora genes had he
avier down fleeces per centimetre length of down. In conclusion, ranki
ng goats for phenotypic down weight using down length explained only 3
6% of variance.
