Rangelands 13 1 february 1991 35 multispecies grazing by cattle and sheep s h m. The performance of sheep and cattle grazing together was compared with that of sheep grazing only with sheep and of cattle grazing only with cattle.
The choice of the system to be used depends largely on the facilities that satisfy two different needs at once.
Cattle and sheep grazing together. Cattle used on average 47 of time grazing 6 walking and 47 ruminating resting whereas sheep spent 49 grazing 4 walking and 47 ruminating resting. The result is that a well managed rotational grazing system can carry more pounds of sheep and cattle than it can carry cattle or sheep alone. No differences p 0 05 in primary activity patterns grazing walking ruminating resting were detected among seasons data not shown thus only overall means are presented.
In general multi species grazing involves grazing two or more species in the same pasture based system. When sheep and cattle grazed together dietary overlap averaged 86. The payoff walker added can be as much as a 24 per cent increase in meat production compared to a cattle only operation.
Tween the effects of grazing animals were not significant until the third year when sheep pastures produced about 20 more dm than cattle pastures table 3. In mixed grazing cattle and sheep may either graze together at the same pasture during one grazing season or alternate in the use of a pasture on an annual basis. Comparisons were made at five stocking rates over three years at the ginninderra experiment station near canberra a c t.
1988 which found 30 35 overlap. Mixed grazing is an alternative pasture management which can be used to increase ruminant performance and reduce gastro intestinal nematodes. The cattle aberdeen angus steers gained less weight in autumn and winter.
Esmall in multispecies grazing cattle and sheep may graze together in a pasture or graze at alternate times these systems have long been utilized in north america europe australia and more recently in africa the primary objec tive of multispecies grazing is to better utilize pastures. Mike and fran wallace have grazed multiple species often 2 or 3 at a time on their ranch since 2000. Almost all of these differences can be accounted for by the decline in ryegrass production from pastures grazed by cattle relative to those grazed by sheep table 5.
A meta analysis was performed on the results of previous studies from the literature to quantify the benefit of mixed grazing with sheep and cattle and identify determinants and enhancing factors. Mike and fran wallace use multispecies grazing with cattle sheep and goats to manage their pastures near nelson neb and diversify their income. They differed from results in western north dakota kirby et al.
One of the most common multi species grazing combinations is cattle and sheep but some producers focus exclusively on small ruminants and run sheep and goats together. These findings were consistent with other research conducted on similar forage types in eastern oregon vavra and sneva 1978 which found dietary overlap of 78 86.
