GROWTH ANALYSIS IN RABBIT USING GOMPERTZ NON-LINEAR MODEL
Abstract: An experiment was
conducted to compare the growth curve of rabbit. Three breeds of rabbit,namely
Indonesian Local Rabbit (IL), Flamish Giant (FG) and Rex (R) were used in the
study.Individual body weights of each breed was measured from birth to 63 days
of age with 3-days interval.Those periodical data were separated into different
sex, be then it was averaged to analysis growthpattern. Growth curve parameters
were estimated to fit growth data. There was no difference in bodyweight
between sexs within breed. Indonesian local rabbit had the lowest body weight.
The resultsshowed that growth curve paramaters among three breeds were
significantly different (P<0.05) for bothsexes. FG had the highest value of
asymptotic mature weight, followed by R and IL. In conclusion,Gompertz model
was excellent fit for the growth data in rabbit with a high coefficient determination
(R2= 0.999).
