| dc.description | Small-scale dairying is an option for campesinos
in Mexico. The costs of feeding are high and
strategies based on quality forages are a priority. The
performance, agronomic variables and feeding costs
were evaluated for dairy cows continuously grazing
perennial ryegrass–white clover for 9 h/day (PRG) or
fed cut herbage from annual ryegrass for 8 weeks
followed by 9 h/day for 6 weeks on a tethered
rotational grazing pattern (ARG). All cows received
3 kg/day of an 18% crude protein (CP) concentrate. A
14-week split-plot on-farm experiment was designed
with 10 cows from two participating farmers, and
1.5 ha per strategy. Milk yield was recorded weekly
and milk composition, live weight and body condition
score were recorded every 14 days. Net herbage
accumulation was greater for ARG (8222 kg organic
matter (OM)/ha) than for PRG (5915 kg OM/ha)
(p<0.05), with higher CP in PRG (p<0.05). Milk
yield was 19 kg/cow per day for PRG and 15.9 kg/
cow per day for ARG (p>0.05). Over 14 weeks, PRG
produced 1422 kg more milk. There were no differences
for live weight or condition score (p>0.05), but
linear regression shows a live weight gain of
0.200 kg/cow per day for PRG. Protein and fat
content showed no differences (p>0.05), but milk
fat content in PRG was below standard. ARG had
60% higher costs, and margins were 38% higher in
PRG. ARG has a place in rain-fed fields. The results
provide viable options for improving these systems
that may be suitable in their socio-economic context
and their social and personal objectives. | |
