Abstract

Tomografi Impedansi Listrik (EIT) merupakan teknologi noninvasif yang menjanjikan untuk memprediksi ciri-ciri kualitas daging, seperti marbling pada daging sapi. Marbling, yang dicirikan oleh lemak intramuskular, secara signifikan memengaruhi kualitas daging sapi dengan meningkatkan rasa, kelembutan, dan kesegaran. Tinjauan ini mengevaluasi penerapan EIT dalam pengendalian kualitas daging, menyoroti kemampuannya untuk mengukur perubahan konduktivitas guna menilai marbling dan atribut kualitas lainnya. Mengintegrasikan EIT dengan teknik pembelajaran mesin semakin menyempurnakan kemampuan prediktifnya. Meskipun EIT menyediakan penilaian noninvasif secara real-time dengan biaya yang lebih rendah, tantangan seperti rasio signal-to-noise yang lebih rendah dan persyaratan algoritma yang kompleks tetap ada. Arah masa depan mencakup integrasi EIT dengan sistem pengemasan modern dan alat otomatisasi untuk meningkatkan pemantauan kualitas daging dan efisiensi industri.

Abstract

Estrus synchronization is a technique used to stimulate estrus and ovulation in a group of animals using hormones. This study aimed to compare three estrus synchronization methods. Fifteen female garut sheep were used and treated with: progesterone-CIDR, double injection prostaglandins, and their combination. At standing heat, ewes were mated with a buck. The parameters measured include the onset estrus, duration estrus, pattern of electrical impedance in the vaginal mucus, number and size of follicles, and pregnancy status. All treated ewes responded to estrus (100%). There were different onset of estrus, namely CIDR (54h), CIDR+PGF2α (41h), and double injection of PGF2α (49.4h), respectively. Meanwhile, the Duration of estrus of CIDR (30,6h), CIDR+PGF2α (29.8h), and double injection of PGF2α (22.4h), respectively. Furthermore, electrical impedance of vaginal mucus at standing heat were CIDR (208Ω), CIDR+PGF2α (189Ω) and double injection of PGF2α (305Ω). The follicle size on H0 to standing heat in each group was significant (p<0.05), while the follicle count was significant only (p<0.05) in the CIDR group. Pregnancy rate was achieved by synchronization with CIDR and double injection prostaglandin (100%) compared to CIDR+PGF2α (40%). It's concluded that the third method of synchronization could result in the best estrus response with slight different characteristics.
