EATING BEHAVIOUR OF SHEEP FED AT DAY AND/OR NIGHT PERIOD
Abstract: The aim of this
research was to determine the eating behavior of sheep which fed at day and/or
night period. Twelve ram average body weight 20.65 + 1.89 kg, CV = 9.15%, and
age ranged from 12 to 18 months were used in this study. Rams were daily fed
pelleted diet at 5% of body weight (BW) in 100% dry matter base. Animals were
assigned to Completely Randomized Design and divided into three groups for
different feeding time treatments. The treatments were day feeding time
(feeding allowed from 0600 to 1800; T0618), night feeding (from 1800 to 0600;
T1806) and whole-day feeding (24 h; T0606), respectively. Parameters observed
in this study were duration of eating, rumination, rest, standing and laying
activity (minute/day), dry matter intake (DMI, g/day) and eating speed
(g/minute). Collected data were analyzed using ANOVA with F-test and if
significantly was found were then analyzed with Duncan test. The results showed
that eating duration (89.71 min/day) and DMI (1034.53 g/day) on T1806 were
significantly lower (P<0.05) than T0618 (117.78 min/day; 1208.75 g/day) and
T0606 (127.5 min/day; 1281.63 g/day) but, the other observation of ruminating,
rest, standing and laying duration and eating speed were found not
significantly different in the all treatments. It can be concluded that feeding
at night period can reduce eating time significantly compared to feeding during
the day period or 24 hours a day, although it results in decreasing feed
consumption.
