MILK PRODUCTION INCREASING OF DAIRY CATTLE AND ENVIRONMENT MANAGEMENT ON SMALL DAIRY FARM USING GRASS CHOPPING

(Nur Kasim Suwardi, Willyan Djaja, dan Lia Budimuljati Salman)

The research was carried out at the Mekarsari group of dairy farmers, North Bandung Dairy Farmers Cooperative (KPSBU), Lembang district, Bandung county for four months. The experiment was 3×4 latin square design and randomized block design. The treatments were grass chopped (2-5 cm and 10-15 cm) and cut grass. The dairy cows were divided into 3 groups based on the lactation period (1st, 2nd, and 3rd). The lactation stage was 6-7 of months. The research was held in 7 days of the adaptation period and 14 days of the data collecting period. The milk yield and samples were collected once in 3 days of 2 weeks. The composting experiment used randomized block design with 3 treatments using chopped grass  (2-5 cm and 10-15 cm) and the cut grass. The treatments were replicated 6 times. The dairy cattle feces and the remaining grass were blended using 1:2 ratio. The obtained data were analyzed using Duncan’s multiple range tests.

The research shoed the result that

1.      Threre is non significant effect of the chopped grass 2-5 cm and 10-15 cm on dry matter consumption (18.41%, 18.06% versus 17.94%), milk production (11.36 kg, 10.21 kg versus 10.43 kg), milk fat (4.01%, 3.92% versus 3.92%), total solid (11.67%, 11.50% versus 11.52%), protein content (3.15%, 3.09% versus 3.11%), milk production energy efficiency (19.10%, 18.055 versus 18.59%), and income over fed cost (2.06, 1.89 versus 1.88).

2.      There is a highly significant effect of the remaining grass chopped 2-5 cm and 10-15 cm increasing the compost production (26.61% and 14.40%).

3.      There is a highly significant effect of the remaining grass chopped 2-5 cm and 10-15 cm increasing the N content of the compost(43.40% and 22.01%).

4.      There is a highly significant effect of the remaining grass chopped 2-5 cm and 10-15 cm decreasing the P content of the compost.

5.      There is a highly significant effect of the remaining grass chopped 2-5 cm decreasing 17.99%  the K content but  the remaining grass chopped 10-15 cm increasing 16.93%.

Key words: milk production, environment management, grass chopping, compost, nutrients content.
