Abstract
ABSTRACT
The present study was aimed to assess the body condition in heifers and cows
during different phases of reproduction and assess its impact on fertility. The Jersey and
Jersey X Red Sindhi crossbreed heifers and cows of the University Livestock Farm and
cattle presented during clinical camps were included in the study. The BCS of heifers
(n=23) was monitored at 1 month interval and related to age at first estrus and cyclicity
pattern. The body condition of heifers improved during 8 months of observation. The
inter estrus intervals of heifers with least BCS (2.95±0.05) were highly regular compared
to heifers with higher BCS (>3). The body condition of farm cows (n=26) was evaluated
one month before calving, at calving and subsequently at one month interval up to 5
months post partum. There was more loss of BCS post partum in anestrus than cyclic
cows. The average daily milk yield of cows with higher BCS before calving was
marginally higher. Among the cows (n=146) and heifers (n=54) presented in different
camps, majority heifers were anestrus while cows were cyclic. The BCS of cyclic heifers
and cows was significantly higher than anestrus animals.
