Winter nutrition for cows
Schalles, R.R.; Drake, C.L.; Kiracofe, G.
Cow productivity on four supplemental winter feeding levels
were compared over 2 years. Cattle were grazed on native bluestem
year round. Cows calved between February 15 and May 5.
Only records (104) of cows that raised a calf in the year considered
were used in this report. Cows averaged 3.3 years old
at birth of calves. Rations fed are given in Table 25 referred
to as group 1, 2, 3 and 4. Cows received the same ration each
year. Cows were allotted to 4 groups and rotated among four
approximately equal pastures so each group remained in each
pasture an equal t:ime. Calves were weighed at birth and cows
and calves were weighed each month. During the first year,
cows were rectally palpated each week after calving until the
first heat to determine time of ovulation and uterine size.
