Penelitian ini bertujuan untuk mengetahui nilai temperature humidity index (THI), heat tolerance coefficient (HTC), konsumsi pakan, dan produksi susu sapi perah Peranakan Friesian Holstein (PFH) pada pemeliharaan di Kelompok Ternak Ngudi Makmur II, Cangkringan, Sleman. Penelitian ini dilaksanakan pada bulan September 2022 sampai Maret 2023. Penelitian ini menggunakan 20 ekor sapi perah laktasi ke-1 dan ke-2 dengan rata-rata bobot badan 461,1±66,2 kg dan body condition score (BCS) 2,5 sampai 3,0. Pakan yang diberikan adalah hijauan dan konsentrat sesuai dengan kebiasaan peternak. Air minum diberikan secara ad libitum. Variabel yang diamati meliputi status faali (temperatur rektal, frekuensi respirasi, frekuensi pulsus) dan HTC, fisiologi lingkungan (suhu, kelembaban) dan THI, konsumsi pakan, serta produksi susu. Data penelitian yang diperoleh dianalisis secara deskriptif menggunakan Microsoft excel 2019. Hasil dari penelitian pada pengukuran status faali menunjukan nilai rata-rata temperatur rektal sebesar 36,75±0,18°C, frekuensi respirasi 56,76±8,18 kali/menit, frekuensi pulsus 67,17±5,32 kali/menit, dan HTC 3,30±0,34. Hasil rata-rata pengukuran fisiologi lingkungan menunjukan suhu lingkungan 26,60±1,08°C, kelembaban lingkungan 89,12±5,85%, dan THI 78,30±2,64. Nilai THI tersebut menggambarkan lingkungan yang ideal bagi sapi perah laktasi. Rata-rata konsumsi BK sebesar 14,53±1,20 kg/ekor/hari, BO 12,98±1,05 kg BK/ekor/hari, PK 1,92±0,23 kg BK/ekor/hari, SK 4,39±0,38 kg BK/ekor/hari, LK 0,40±0,07 kg BK/ekor/hari, dan TDN 8,13±0,72 kg BK/ekor/hari. Rata-rata persentase BK terkonsumsi dari berat badan adalah 2,77%. Rata-rata produksi susu sebesar 13,98±3,21 L/ekor/hari. Kesimpulan. Sapi perah laktasi di Kelompok Ternak Ngudi Makmur II, Cangkringan, Sleman memiliki nilai HTC dan THI pada kondisi heat stress ringan, meskipun begitu konsumsi pakan dan produksi susu sapi perah masih baik. 

This study aims to determine the values of temperature humidity index (THI), heat tolerance coefficient (HTC), feed intake, and milk production of Friesian Holstein Crossbred cows raised at Ngudi Makmur II Dairy Farmer Group, Cangkringan, Sleman. The study was conducted from September 2022 to March 2023. The study used 20 first and second lactation dairy cows with an average body weight of 461.1 kg and body condition score (BCS) of 2.5 to 3.0. The feed given was forage and concentrate according to the farmers' habits. Drinking water was given ad libitum. The variables observed included the faali status (rectal temperature, respiratory rate, pulse rate) and HTC, environmental physiology (temperature, humidity) and THI, feed intake, and milk production. The research data obtained were analyzed descriptively using Microsoft Excel 2019.The results showed that the average rectal temperature was 36.75 ± 0.18°C, respiratory rate was 56.76 ± 8.18 times/min, pulse rate was 67.17 ± 5.32 times/min, and HTC was 3.30 ± 0.34. The average environmental physiology measurements showed that the temperature was 26.60 ± 1.08°C, humidity was 89.12 ± 5.85%, and THI was 78.30 ± 2.64. THI indicated an ideal environment for lactating cows. The average dry matter intake was 14.53 ± 1.20 kg DM/head/day, organic matter intake was 12.98 ± 1.05 kg DM/head/day, crude protein intake was 1.92 ± 0.23 kg DM/head/day, crude fiber intake was 4.39 ± 0.38 kg DM/head/day, crude fat intake was 0.40 ± 0.07 kg DM/head/day, and total digestible nutrient intake was 8.13 ± 0.72 kg DM/head/day. The average milk production was 13.98 ± 3.21 L/head/day. The lactating dairy cows in Ngudi Makmur II dairy farmer group, Cangkringan, Sleman have HTC and THI values on mild heat stress condotion. However, the feed intake and milk production of lactating dairy cows are still good.
