Evaluation of Carrying Capacity of Grass Forages on KPSP Setia Kawan Nongkojajar, Pasuruan, East Java

Abstract

Carrying capacity is the ability of pasture to produce forage required by a number of livestock grazed in one hectare or the ability of pasture to accommodate livestock per hectare. Carrying capacity calculations are carried out based on the available forage production using animal units. Animal Units (AU) are a measurement used to relate livestock body weight to the amount of livestock food consumed. This research aims to determine the carrying capacity on land owned by KPSP Setia Kawan and determine the nutrient content of Setia grass and Pakchong grass. Forage sampling uses the sampling method by determining the sampling point and then taking forage samples with an area of 1x1m2. The data collected was primary data which is presented descriptively. The nutrient content of Setia grass on KPSP Setia Kawan land yields dry weight, crude protein, crude fat, crude fiber, ash, extract ingredients without nitrogen, total digestible protein resepectively are 86.37%; 17.18%; 1.36%; 29.86%; 13.06%, 38.54%, 59.05%. The content of pakchong grass obtained dry weight, crude protein, crude fat, crude fiber, ash, extract ingredients without nitrogen, total digestible protein resepectively are 68.70%; 9.60%; 3.66%; 30.39%; 14.39%; 41.96%; 59.05%. Carrying capacity on the KPSP Setia Kawan land for Setia Grass accommodates 53.24 AU and Pakchong Grass accommodates 29.64 AU. The total land area of 20,000 m² can accommodate 82.88 AU for one year so KPSP Setia Kawan needs to be maximized of excisting land.
