The Effect of Bali Cattle Grazed Under Coconuts on lntroduced Pasture to The Weight Gain of Cattle and Botanical Composition

Abstract

Four groups of Bali female cattles each three heads (per group) which 187,25 kg
average weight was grazed on 4 differences mix-pastures in 4 blocks (each one Ha wide). The light intensity under coconuts was 75% light. Block one was planted witl1 Paspalum notalum cv. Coinpetidor + Arachis pintoi cv. Amarillo, block two was
planted by Slenotaphrum secundalum cv. Floratam + Arachis  pinloi cv. Amarillo, block three was planted by Stenolaphrum  secundatum cv. Floratam + Calliandra calothyrsus and block four was natural pasture. The block was not replicated. The
highest cattle weight gain in 90- days grazing was 326 gram/day in block three and then was followed by block two and block one each was 302 gram/day and 285 gram/day. The lowest cattle weight gain was 159 gram/clay in block four, in natural pasture. The botanical composition of the pasture which was  grazed a year afier planting in 90 days grazing time by three cattles per ha each block and then was continued by overgrazing in one year was: Srenolaphrum  secundnlum sprcaded very well (increasing till 48,9% in block two). Paspalum  notatum sprcaded slower (increasing only 20,8% in block one). Arachis pintoi sprcaded proverly. Alter one and half year old, Arachis pintoi sprcaded till 28,3% in block one and 25,7% in block two. The last measuring composition of Arachis  pintoi decreased till 15,4% in block one and 12,5% in block two, due to overgrazing treatment in one year. Calliandra calothyrsus decreased rapidly under grazing, because cattle eat Calliandra first. In 90 days under grazing Calliandra decreased a lot and mostly of it was barked by cattle and then died. Calliandra was not suitable grazed directly look like would be better with cut and carry system.
