METABOLIC AND BEHAVIORAL PARAMETERS IN NEWBORN PIGLETS IN RELATION TO BIRTH ORDER
Keywords:
newborn piglets, first suckle, glycemia, temperatureAbstract
The experiment had 2 phases:During the first phase 19 sows were monitored during
farrowing; the piglets were numbered according to birth order, they were weighed
and there were recorded the time each piglet was born and when it first suckled.
There was calculated the time from the beginning of the farrowing until the time
each piglet was born (∆TNPP) and the time from birth until the first suckle (∆TPS).
A statistical correlation was established between these parameters.During the
second experimental phase, for 49 piglets from 5 sows were determined: birth
weight, ∆TPS, glycemia at birth (G0) and after the first suckle (G1), rectal
temperature at birth (T0) and after the first suckles (T1). This data was statistically
analyzed using the Mann-Whitney U test).Respecting the birth order, ∆TPS is
shorter for piglets born last (p<0.05). Average ∆TPS was 23.04±2.49 minutes;
during this time glycemia rises from 58.35 mg% to 64.35 mg% and rectal
temperature drops from 38.58°C to 37.35°C. T0 is positively correlated with G0
(p<0.01) with G1 (p<0.01) and T1 (p<0.01). G0 is highly correlated to G1
(r=0.8855; p=0).
