Recommended Level

It is well established that zinc is an essential micro-nutrient required to maintain health and performance in dairy cows (Underwood and Suttle, 2004). Cattle diets are traditionally supplemented with inorganic minerals (e.g. zinc oxide), but these may be poorly absorbed, resulting in an economic and environmental cost due to excess minerals being excreted. It is claimed organically bound minerals are able to resist interaction before and at the absorption site in the small intestine (Power, 2006), which may result in a lower dietary inclusion rate being required. The objective of the current experiment was to investigate the effect of an organically bound source of Zn as a replacement for inorganic Zn on dairy cow health and performance when supplemented at and below the recommended level.

And Performance

In order to understand the complex changes associated with lactation in the dairy cow it is necessary to assess the contribution of the non-carcass components. It has been shown with sheep (Cowan, Robinson, Greenhalgh and McHattie, 1979) that a number of tissues may be mobilised during lactation with a redistribution of tissues particularly towards the gut and udder, and that diet may have a significant effect. Butler-Hogg, Wood and Bines (1985), using Friesian dairy cows showed changes in the weights of guts, internal fat depots (omental, mesenteric and perinephric) and liver with stage of lactation although the number of stages examined was somewhat limited. The present experiment investigates changes in non-carcass component weights at 9 points over the first 29 weeks of lactation and with 3 levels of concentrate supplementation.

The objective of this study was to evaluate the effects of the rumenocentesis procedure on dairy cows by determining selected metabolic and physiological variables representing the health status. Two groups of 6 cows either underwent rumenocentesis (GA) or sham (GB) procedures. Superficial skin temperature of the rumenocentesis area was measured using infrared thermography before the procedure (-1 h), immediately after (0 h), and at 48 h, 96 h, and 20 days following rumenocentesis. Blood samples were collected at all times, except for immediately after the procedure (0 h), and selected immunologic response variables were determined. Milk yield and rectal temperatures were measured daily. Rumenocentesis did not influence the white blood cell count, haptoglobin or total protein concentrations. Electrophoretic protein fractions were not different between GA and GB treatments. Milk yield and rectal temperature were not affected by rumenocentesis. Skin temperature of the rumenocentesis region in GA group cows increased by 1.0 °C immediately after rumenocentesis and returned to baseline after 48 h where it remained constantly until the end of the study; similar to observation in GB group cows. Results of this study would suggest minimal adverse effects on cow health and production when performing rumenocentesis for the diagnosis of subacute ruminal acidosis. Additional more intensive studies addressing animal welfare issues relative to the diagnostic techniques are needed.

ABSTRAKPeningkatan produktivitas ternak dapat dicapai melalui perbaikan aspek teknis pemeliharaan yang meliputi perbaikan genetik, pakan, pengelolaan, perkandangan dan kesehatan ternak. Penelitian ini bertujuan untuk mengevaluasi penerapan aspek teknis pemeliharaan sapi perah berdasarkan Good Dairy Farming Practices (GDFP) pada peternakan sapi perah rakyat di Cibungbulang. Metode penelitian yang digunakan adalah survei dan pembagian kuisioner, observasi serta pengukuran langsung. Data dianalisis secara deskriptif dan disajikan dalam bentuk frekuensi tabulasi untuk menggambarkan karakteristik penerapan setiap aspek pemeliharaan sapi perah. Hasil penelitian menunjukkan bahwa pelaksanaan aspek teknis pemeliharaan sapi perah berdasarkan Good Dairy Farming Practices (GDFP) di peternakan rakyat Cibungbulang sebesar 69,75% pada musim hujan dan 67,25% pada musim kemarau. Aspek kesehatan ternak memperlihatkan nilai yang sangat rendah baik pada musim hujan maupun musim kemarau sehingga perlu mendapatkan perhatian khusus agar produktivitas ternak dapat ditingkatkan secara optimal.Kata kunci: biji kecipir, Trichoderma viride, pH, suhu, protein, serat kasarABSTRACTIncreased dairy cow productivity can be achieved through improving the technical aspects of maintenance which include genetic improvement, feed, management, housing and dairy cow health. This study was done to evaluate the application of the technical aspects of dairy cow maintenance based on the Good Dairy Farming Practices (GDFP) on smallholder dairy farm in Cibungbulang. The research method used was a survey and distribution of questionnaires, observations and direct measurements. Data were analyzed descriptively and presented in frequency tabulations to describe the characteristics and application each aspect of dairy cow maintenance. The results showed that the implementation of technical aspects of dairy cow maintenance was based on the Good Dairy Farming Practices (GDFP) at smallholder dairy farm in Cibungbulang i.e 69.75% in rainy season and 67.25% in dry season. The health aspect of dairy cow shows a very low value both in rainy and dry season so need special attention to increased productivity optimally.Keywords: dairy cow, technical aspects of maintenance, GDFP
