ABSTRACT

Growth Index
of piglets (n=70) of Instructional Livestock Farm, Apollo College of Veterinary
Medicine, Jaipur was studied from birth (day one) to one month of age. Crown
rump (CR) length, girth and height were measured with the help of meter scale
and thread. The weight was taken with the help of monopan balance. The data
revealed a variable increase for different parameters on different days.
However, all the parameters increased more (1.5 to 4 times) in early (week one
to two) part of the month except CR length, which increased slightly more during
the period of two to four weeks. The CR length, girth, height and weight
revealed a total increase of 101.73, 110.65, 160.25 and 620.23% respectively
from birth to one month of age. The piglets gained 21.67 mean per cent weight
per day in contrast to mean percent increase in height (5.34 percent), girth
(3.67 per cent) and CR length (3.50 percent).

KEYWORDS: Growth Index, CR Length, Girth, Height,
Piglets.

INTRODUCTION

Prenatal growth index of goat (Malik et al., 1992) and brain along with its ventricular system of chick
embryos (Malik and Singh, 1978) have been reported. However, such studies in
pigs appear meager. Hence the present study was undertaken to know the overall
growth of the piglets in relation to age with reference to CR length, girth, height
and weight on different days during the first week and at a weekly interval
from first to fourth weeks of age.

MATERIAL AND METHODS

Seventy normal piglets were procured from the Instructional
Livestock Farm, Apollo College of Veterinary Medicine, Jaipur for the present
study. The piglets were divided into ten equal groups (seven in each group).
First seven groups were monitored daily and later three groups at an interval
of one week. The piglets were weighted in weighing machine/monopan balance
while CR length, girth and height of piglets were taken with the help of meter
scale and thread. Mean, standard error and growth spurt (Percentage increase
between two successive periods) and a total increase (from birth to one month
of age) for each parameter were calculated by standard method (Snedecor and
Cochran 1994).

RESULT AND DISCUSSION

The mean and standard error of CR length, girth, height and weight
of piglets are shown in Table 1 and their percentage increase in Table 2 and in
Figure.
