| Sumario: | The main objective of this study was to evaluate
the in vivo characteristics, body parts, production
costs and calculate regression equations for the
main traits of commercial interest the goats. For
this study cross Angorá goats, controlled during
one year and slaughtered at 11-12 months (lot 1,
n=20) were used. From the results of lot 1, a
second lot (lot 2, n=14) with animals 8-9 months
old, was tested. Both batches were reared under
extensive system in the territory of the Alto
Camaquã (State of Rio Grande do Sul, Brazil). The
goats slaughtered at the age of 11-12 months had
production costs of R$ 0.93 kg live weight and R$
1.86 kg/carcass and reached slaughter weight as
early as 6-7 months of age. The regression
equations determined that the thoracic perimeter
is the best measure to estimate the fasting weight,
since the body compacity is better estimated by
fasting weight. The goats slaughtered at 8-9
months had higher values for the main traits when
compared to those slaughtered at 11-12 months.
Most of the body parts surveyed showed isogonic
behavior. The results indicate that kids reared
under extensive management at Alto Camaquã
territory must be slaughtered before winter period,
and the optimum age for slaughter is 8-9 months
with body weight around 22 kg. |
