RESUMO
This study was conducted to determine the nutrient status, changes in the hematological and selected blood metabolites profile of mid-lactating dairy cows during wet and dry seasons under Indonesia's tropical environment. Forty mid-lactating FH cows were selected from the Livestock Farm Complex (Dairy Community) in Yogyakarta, with an average body weight of 421.77±28.60 kg and 1st to 3rd lactation. They were housed in a semi-open housing system with concrete flooring covered with rubber mats and provided with feeders and drinkers. They were fed twice daily, and drinking water was given ad libitum. Measurements were made on the intakes of feed (and nutrients). The variables measured were nutrient intakes, blood hematology, and metabolites profile and measured over two seasons, namely wet and dry seasons. The results of the measurements made were compared using independent t-test analysis. The result indicated that intake of CP, RLYM, RNEUT, NEUT, RBC, HGB, MCV, MCHC, MPV, albumin, urea nitrogen, and total protein was differed significantly (P < 0.05) between wet and dry seasons, respectively. It was concluded that the nutrient status of mid-lactating dairy cows in the wet season was higher than during the dry season, especially the intake of CP. In the wet season, it has a positive effect on the basic hematological parameters.

The background of this study was blood profile and cows' behavior that could be used as a tool to diagnose reproductive status in the dairy cows. This research was aimed to determine biochemical blood profile, progesterone level, and behaviors of Friesian Holstein crossbreed dairy cow in the tropical climates. Fifteen Friesian-Holstein crossbreeds cows, in early lactation, reared by local farmers were divided into two barn types: individual and groups of cows. Blood samples were collected from the jugular vein using a 22G needle on days 0, 14, and 28. For the determination of blood profile, blood was collected into Vacuntainer® blood tubes containing ethylenediaminetetraacetic acid (EDTA) to arrest glycolysis. The blood was transported to the laboratory with a coolbox. The concentration of progesterone in plasma was assayed byenzyme-linked immunosorbent assay (ELISA) using a commercial kit and the biochemical blood profile serum was measured by using microlab 300. The variables observed were glucose, cholesterol, urea, and non-pregnant progesterone. Data obtained was examined by T-test analysis. The result showed that the Temperature-Humidity Index were 81.3 and 79.6 respectively, there were no significant differences between two observation, in terms of total feeding time (3.06±0.48 and 2.91±0.22 hours/day), total water consumption (86.23±0.58 and 85.37±0.88 l/day), total standing (12.70±0.21 and 12.83±0.34 hours/day), total laying (11.30±0.71 and 11.16±0.62 hours/day). The blood profile and progesterone levels were lower than the normal range in dairy cows. Also, the result indicated that blood parameters were not significantly different (P > 0.05) between individual pen and group. The result indicated that the progesterone level was not significant in two models of management dairy cows. The conclusion of the research is the climate can affect behavior and the blood parameters. Blood profiles [...].

In tropical Indonesia, which has specific dry and wet seasons, it is difficult to provide high-quality forage in sufficient quantities throughout the year. Therefore, it is necessary to establish the availability and nutrient contents of forages and other natural feed resources during the dry and wet seasons in order to provide sufficient nutrients throughout the year, as an improvement effort the productivity of dairy cows. The method used was surveys conducted at dairy smallholder and groups selected in one of the areas of dairy cooperative in Yogyakarta; and observed environment condition (temperature and humidity). Feed samples were taken and analyzed in the Laboratory of Dairy Science and Milk Industry, Faculty of Animal Science UGM. Supplies of forages, agricultural by-products, feedstuffs, and commercial concentrates were available throughout the year, although the amounts were limited. Most of dairy smallholders had greater access to forages and agricultural by-products during wet season than during the dry season; this resulted directly in a better productivity of dairy cows during the wet season. In both seasons, farmers purchased commercial concentrates from other areas to support the cows feed requirements. Smallholder dairy farmers in the dairy areas of Yogyakarta had better access to forages and agricultural by-products during the wet season than during the dry season, but need to supplement their animals with commercial concentrates obtained from outside areas during both seasons. Assuring the continuity and availability of forages and concentrate in this area is of dire importance to reduce the dependency of feed from outside of the region.
