Abstract

Pertumbuhan dan produksi bahan kering Rumput Gajah (Pennisetum purpureum Schumach) dan Sorgum (Sorghum bicolor Moench) pada pemberian tiga tingkat pupuk kandangtelah diteliti selama lima bulan. Total pupuk kandang segar yang digunakan pada tiap tingkat pemupukan adalah 250 tonha (pemupukan tinggi), 150 tonha (pemupukan sedang) dan 10 tonha (pemupukan rendah). Produksi bahan kering, tingkat perhmbuhan tanaman dan indeks luas permukaan daun pada Rumput Gajah cenderung meningkat dengan rnenhgkatnya pemberian pupuk kandang, namun tidak berbeda nyata antara pemupukan tin& dan sedang. Produksi bahan kering, tingkat pertumbuhan tanaman dan indeks luas permukaan daun pada Sorgum berbeda nyata diantara perlakuan dan cenderung meningkat dengan meningkatnya pemberian pupuk kandang. Hubungan antara indeks luas permukaan dam dan tingkat pertumbuhan tanaman adalahlinier positif, tingkat pertumbuhan tanaman cenderung meningkat dengan meningkatnya indeksluas permukaan daun.

Abstract

ABSTRACTThis research aims to know the impact of repeat breeding on the reproduction efficiency of dairy cattle in Enrekang Regency, South Sulawesi. It was conducted from April to November 2021 in Enrekang regency. This research used 102 dairy cattle of Friesian Holstein (FH). The research design used nonprobability sampling with the purposive sampling method. The samples were grouped based on three parities, namely Nuliparous, Primiparous, and Pluriparous. Prevalence data of repeat breeding was obtained from reproduction efficiency evaluation that was seen from a success of the first AI. If pregnancy does not occur in the first AI, it is repeated in the second AI until the third AI. The result shows that the prevalence of repeat breeding in dairy cattle of FH at the parity of Nuliparous had shown a lower percentage (3,44%) compared to the parity of Primiparous and Primiparous (31,57% and 29,62%). The prevalence of the three parities was tangibly different (significant) with p-value <0,05. Reproduction efficiency of dairy cattle of Nuliparous parity was higher than Primiparous and Pluriparous with value S/C (1,5 vs 2,76 vs 2,52) and CR (65,51% vs 47,36% vs 53,70%). The lower the prevalence value of repeat breeding, the better reproduction efficiency.Keywords: Conception Rate, Reproduction Efficiency, Repeat Breeding, Service Per Conception
