Abstract
This study aims to determine the amount of nutrients given in feed for bali cows in Bali in different seasons. The study used a survey method through observations on 27 livestock groups in Bali by measuring the amount of feed given, diversity of feed ingredients, and sampling of feed ingredients for analysis. Measurements were made three times, namely in the rainy season (February-March), mid-dry season (June-July), and the peak of the dry season (September-October). The results showed a decrease in the type and diversity of feed ingredients in the ration, while the amount of ration given (kg/day of fresh weight) was almost the same (33.17; 33.15; and 32.82 kg). The total protein available in the ration was decreased in the rations given, namely: 706.52 g (rainy season), 648.65 g (mid-dry season), and 611.37 g (peak dry season). While the total energy tends to increase according to successive seasonal changes: 12,650.70; 13,820.18; and 13,974.21 kcal ME. From this study it can be concluded that although there is a decrease in the type and diversity of feed ingredients in the rations given to bali cows according to the season in Bali, but the amount of protein and energy above the basic livelihood needs of livestock.
