Konsumsi Nutrien, Karakteristik Estrus, serta Metabolit Darah Kambing Boerja Reproduksi Awal yang Diberi Kalsium Mikro dan Nano

Abstract

Penelitian ini bertujuan menganalisis perbandingan antara pengaruh pemberian kalsium mikro dan nano terhadap konsumsi nutrien, karakteristik estrus, ciri fisik vulva, dan metabolit darah kambing Boerja betina pada fase reproduksi awal. Penelitian ini menggunakan 10 ekor kambing dengan rataan body condition score (BCS) 2,85±0,32 yang diuji menggunakan rancangan acak lengkap (RAL) 2×5. Perlakuan terdiri dari A1 = Kalsium mikro dan A2 = Kalsium nano. Analisis data menggunakan Independent T-test dan secara deskriptif menggunakan Stacked Bar Chart untuk data ciri fisik vulva (warna, bentuk, dan kondisi lendir). Hasil penelitian menyimpulkan bahwa pemberian kalsium mikro dan nano menghasilkan onset estrus yang serupa. Kalsium nano mampu memperpanjang durasi estrus hingga menyeragamkan ciri fisik vulva, sementara pemberian kalsium mikro menghasilkan nilai panjang, lebar, serta pH vulva yang lebih tinggi. Pemberian kalsium nano dinilai unggul meningkatkan kualitas ekspresi estrus dalam mendukung fase reproduksi awal kambing Boerja betina

This study aimed to analyze the comparative effects of micro and nano-calcium supplemention on nutrient intake, estrus characteristics, vulva physical characteristics, and blood metabolite in Boerja does during the early reproductive phase. This study used 10 does with an average body condition score (BCS) of 2.85±0.32 were tested using a 2×5 completely randomized design (CRD). The treatments consisted of A1 = Micro-calcium and A2 = Nano-calcium. Data were analyzed using the Independent T-test and descriptive analysis using Stacked Bar Charts for vulva physical traits (color, shape, and mucus condition). The study concluded that micro and nano calcium induced a uniform estrus onset. Nano-calcium was able to extend the duration of estrus, standardize the physical traits of the vulva, whereas vulva length, width, and pH were higher in the micro-calcium group. Nano-calcium content was superior in improving the quality of estrous expression in supporting the early reproductive phase of female Boerja goats.
