The potential of the development of Holstein crossbreed dairy cows intropical lowland Indonesia: study of physiological and milkproduction by body cooling treatment

The research aimed to evaluate the effectiveness of body cooling techniques on physiological and milk production of Holstein crossbred dairy cow at lowland area during the dry season. Three treatments have been done for 30 days that were: none, fans, and water sprinkling cooling, for 30 minutes each at 08.00 and 11.00 h. The effects of treatment are not significant (P > 0.05) on air temperature, RH, THI, respiration rate, heart rate, and heat tolerance coefficient. The rectal temperature by sprinkling (38.76 °C) was within the normal range, lower (P 0.05) on milk production, dry matter, TDN and crude protein intake. The research highlighted that water sprinkling was effective in maintaining normal physiological condition of Holstein crossbreed cows in hot lowland environments.

Phenotypic characteristics of local cattle in Madura Island

The aim of the research is to (1) analyze phenotypic variance both qualitative and quantitative characters in Madura cattle, (2) to analyze the relationship between that characters and body weight. Cattle studied were located in Waru and Pademawu subdistrict, Pamekasan district, Indonesia. The sampling technique was accidental sampling. Subject animals were 8–20 month-old cows, grouped into 2 age groups of 1 years old. Both qualitative and quantitative phenotypic characteristics were recorded. Qualitative characteristics were the color of the body, white color in bottom and leg, black color at the back, and the presence of horns. Quantitative characteristics were the head index, body weight, chest girth (CG), body height (BH), body length (BL), and body condition score (BCS). Data were analyzed with correlation and regression analyses. Results showed that qualitative characteristics of the Madura local cattle were all those of the reference Madura cattle standard, such as the white color of leg an...
