| dc.description.abstract | Dairy cows are the large ruminants that mostly kept by Indonesian dairy farmers. The dairy farms of Indonesia located not only in the villages, but also in the urban areas, such as Pondok Ranggon in East Jakarta. Recent study was done to observe effect of technical factors on milk production and quality of dairy farms in Pondok Ranggon in East Jakarta. The parameters were environmental conditions, feeding patterns, animal conditions, lactation performance, and milk quality. The data were analyzed using multiple regression analysis. To overcome less of roughage supply, farmers used agro-industry by products such as tofu waste, soybean waste, and rice bran. The averages of roughage, concentrate, tofu waste, soybean waste and rice bran that offered to the animals were 20,85±4,27; 0,67±0,73; 28,94±7,62; 2,26±4,51; and 0,01±0,09 kg/h/d, respectively. Under this feeding regime, the average milk produced was 9,28±3,22 kg/h/d. The averages of fat, lactose, protein, solid non fat, density of milk quality were 4,44%; 4,20%; 3,91%; 8,83%; and 1,032 g/ml. The relationship of milk production(Y) on roughage (X1), concentrate (X2), tofu waste (X3), soybean waste (X4) and rice bran (X5) was Y1=2,672X10,256 X20,014 X30,018 X4-0,008 X5-0,055. The influenced of age, number of lactation, lactation days, pregnancy and body weight on milk production and quality were also confirmed. It was concluded that maximum milk production in Pondok Ranggon was produced by the cows at 2,5 years age, in the first lactation, at the second months of lactation, from heavier cows, or in the non pregnant cows. | en |
