Abstract
This study aimed to determine the effect of cage microclimate manipulation with misting on physiological responses and heat resistance of goats (Sapera and Ettawa Grade). This research was conducted in April - May 2020 at Telaga Rizki People's Farm, Metro City, Lampung Province. This study used an experimental method, Split Plot design with a completely randomized design (CRD). This study used two treatments, namely modification of the pen consisting of pens without misting (K0) and pens with misting (K1) and two breed of goats, namely Sapera and Ettawa Grade (PE) goats. Each treatment was carried out 3 times. Goats as subplots and microclimate modification of the pen as the main plot. In this study, twelve female goats were used, namely 6 Sapera goats and 6 Ettawa Grade (PE) goats aged 2-3 years. The parameters observed were microclimate condition, namely air temperature, relative humidity (RH), and Temperature Humidity Index (THI), and physiological responses including rectal temperature, respiration frequency, heart rate frequency, and heat tolerance (HTC). The results of the research showed that there was significant effect (P<0.05) of treatments on RH and THI. The resilts also showed that there was no significant effect (P>0.05) of treatments on rectal temperature, heart rate, respiration frequency, HTC and environment temperature.

Highlights
Penelitian ini bertujuan untuk mengetahui pengaruh manipulasi iklim mikro kandang dengan pengkabutan pada kambing Sapera dan Peranakan Ettawa (PE) terhadap respons fisiologis dan daya tahan panas
Data respon fisiologis yang diperoleh dianalisis dengan sidik ragam (ANOVA) taraf 5% dan apabila terdapat pengaruh dianalisis lanjut menggunakan BNT (Stell dan Torrie, 1991) dan data mikro klimat di analisis dengan Independent Student T-Test (Gaspersz, 1991)
Pengaruh iklim terhadap respon Sapi Peranakan Fries Holland dan modifikasi lingkungan untuk meningkatkan produktivitasnya
Summary
Penelitian dilaksanakan di Peternakan Rakyat Telaga Rizki, Kota Metro. Penelitian berlangsung pada April hingga Mei 2020. Pada penelitian ini digunakan 12 ekor kambing, yaitu kambing Sapera 6 ekor dan Peranakan Ettawa (PE) 6 ekor yang berumur 2-3 tahun. Penelitian ini menggunakan 2 perlakuan yaitu perlakuan modifikasi iklim kandang terdiri dari kandang tanpa pengkabutan (K0) dan kandang dengan pengkabutan (K1) sebagai petak utama, serta perlakuan bangsa kambing Sapera (S) dan Peranakan Ettawa (P) sebagai anak petak, masing-masing perlakuan dilakukan 3 kali ulangan. Pengakabutan dilakukan setiap hari pada pukul 10.00--14.00 WIB dengan menggunakan kecepatan angin 1 dan tuas kabut setengah. Pemberian pakan dilakukan setiap pagi pukul 06.30 dan sore hari pukul 16.00 WIB, pakan yang diberikan yaitu masing-masing 1 kg ampas tahu, konsentrat, dan silase daun singkong. Parameter yang diamati terdiri atas iklim mikro (suhu udara, kelembaban udara relative (RH), dan temperature humidity index (THI)), dan kondisi fisiologis (suhu rektal, frekuensi respirasi, frekuensi denyut jantung, heat tolerance (HTC)).
