Respons Fisiologis Sapi Perah Peranakan Ongole Terhadap Perubahan Mikroklimat Kandang

Abstract

Produktivitas peternakan dipengaruhi oleh sejumlah faktor, termasuk kualitas genetik hewan dan faktor-faktor lingkungan di lokasi tempat ternak dipelihara. Ternak sapi perah yang tidak tahan terhadap cekaman panas mengakibatkan penurunan konsumsi pakan yang akhirnya berdampak pada rendahnya tingkat produktivitas. Penelitian ini bertujuan melihat perubahan mikroklimat kandang, respons fisiologis, aktivitas kadar superoksida dismutase (SOD), serta mencari regio alternatif selain regio rektal dalam pengukuran suhu. Penelitian ini mengukur mikroklimat kandang berupa suhu, kelembapan kandang, dan temperature humidity index menggunakan thermohygrometer, frekuensi denyut jantung menggunakan stetoskop, suhu rektal menggunakan termometer, dan suhu permukaan menggunakan kamera termal inframerah. Jumlah sapi yang digunakan sebanyak 6 ekor sapi perah betina Peranakan Ongole dan dilakukan pada 2 waktu yaitu pagi dan siang selama 5 hari saat cuaca panas. Hasil dari penelitian menunjukkan perubahan dengan hasil yang signifikan (p

Livestock productivity is influenced by a number of factors, including the genetic quality of the animals and environmental factors in the location where the animals are kept. Dairy cattle that are not resistant to heat stress result in decreased feed consumption, which in turn leads to lower productivity levels. The aim of this study was to assess changes in housing microclimate, physiological responses, superoxide dismutase (SOD) activity, and to find alternative regions to the rectal region for temperature measurement. This study measured cage microclimate in the form of temperature, cage humidity, and temperature humidity index using a thermohygrometer, heart rate frequency using a stethoscope, rectal temperature using a thermometer, and surface temperature using an infrared thermal camera. The number of cows used was 6 female Peranakan Ongole dairy cows and was carried out at 2 times, namely morning and afternoon for 5 days during hot weather. The results of the study showed changes with significant results (p<0.05) in the data of cage microclimate and physiological responses, but not in superoxide dismutase activity (p>0.05). Alternative regions with values close to rectal temperature are found in the vulva, costalis, udder, and occularis regions, but the most ideal region in measuring temperature using a thermal camera is the occularis region.
