Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis respon konsumsi nutrien sapi perah laktasi serta hubungan temperature humidity index (THI) terhadap konsumsi bahan kering (BK) pada musim kemarau di kelompok ternak Ngudi Makmur II, Cangkringan, Sleman, Yogyakarta. Penelitian ini dilaksanakan pada bulan September 2019 sampai November 2019. Penelitian ini menggunakan 10 ekor sapi perah Friesian Holstein (FH) periode mid laktasi. Pakan yang diberikan adalah hijauan dan konsentrat dengan proporsi sesuai yang biasa diberikan oleh peternak di kelompok ternak Ngudi Makmur II. Air minum diberikan secara ad libitum. Variabel yang diamati adalah komposisi nutrien bahan pakan, konsumsi nutrien (bahan kering (BK), bahan organik (BO), protein kasar (PK), lemak kasar (LK), serat kasar (SK), dan total digestible nutrients (TDN)), pengukuran temperatur dan kelembaban, serta perhitungan nilai THI. Analisis sampel dilaksanakan di Laboratorium Ilmu Ternak Perah dan Industri Persusuan, Fakultas Peternakan, Universitas Gadjah Mada, Yogyakarta. Data konsumsi nutrien dan nilai THI dianalisis dengan metode analisis deskriptif. Selanjutnya data konsumsi BK dengan nilai THI dianalisis lanjut dengan korelasi dan regresi. Hasil penelitian menunjukkan konsumsi BK 14,39 ± 2,56 kg BK/ekor/hari, BO 12,27 ± 2,26 kg BK/ekor/hari, PK 1,73 ± 0,27 kg BK/ekor/hari, SK 2,90 ± 1,00 kg BK/ekor/hari, dan TDN 9,09 ± 1,52 kg BK/ekor/hari. Data rata-rata temperatur, kelembaban udara, dan nilai THI setiap harinya berturut-turut 26,27 ± 0,69b°C, 87,94 ± 3,54% dan 76,00 ± 3,12. Nilai THI mempunyai korelasi negatif terhadap konsumsi BK dengan derajat hubungan korelasi lemah. Kesimpulan dari penelitian ini adalah sapi FH pada musim kemarau di Kelompok Ternak Ngudi Makmur II, Cangkringan memiliki nilai THI yang menyebabkan heat stress ringan pada sapi perah, meskipun begitu konsumsi BK pakan ternak telah tercukupi kebutuhannya.

This study aims to identify and analyze the response to nutrient intake of lactating dairy cows and the relationship between temperature humidity index (THI) and consumption of dry matter (DM) in Ngudi Makmur II dairy farmers group, Cangkringan, Sleman, Yogyakarta, during dry season. The study was conducted in September until November 2019. This study used 10 Holstein Friesian dairy cows in the mid-lactation period, which was fed with forages and concentrates in the usual of the farmers feeding. Water provided by ad libitum. The variables measured were analysis of the composition of feed ingredients, feed intake ((dry matter (DM), organic matter (OM), crude protein (CP), extract ether (EE), crude fiber (CF) and total digetible nutrients (TDN)), measuring temperature and humidity, and calculating the THI value. The sample were analyzed in the Laboratory of Dairy Science and Milk Industry, Faculty of Animal Science of Universitas Gadjah Mada, Yogyakarta. The feed consumption, and THI value data obtained from this study were being analyzed descriptively. Then, the data of DM intake with the THI value were analyzed by regression and correlation. The results of the study showed that DM 14.39 ± 2.56 kg DM/head/day, BO 12,27 ± 2.26 kg DM/head/day, CP 1.73 ± 0.27 kg DM/head/day, CF 2.90 ± 1.00 kg DM/head/day and TDN 9.09 ± 1.52 kg DM/head/day. The average data of temperature, humidity, and THI value every day were 26.27 ± 0.69 °C, 87.94 ± 3.54% and 76.00 ± 3.12. The THI value has negative correlation to DM consumption with low degree of correlation. From this research, we can conclude that the THI value of Holstein Friesian cattle in Ngudi Makmur II caused lowheat stress in dairy cattle but nutrient consumption was fullfilled.
