Abstract

ABSTRACT. Penelitian ini bertujuan mengetahui pengaruh optimalisasi penggunaan Bungkil Inti Sawit/Bungkil Inti Sawit Fermentasi dalam ransum terhadap bobot potong, karkas, persentase karkas, bobot lemak abdominal, potongan dan persentase komersil karkas serta kualitas daging ayam SenSi-1 Agrinak umur 10 minggu. Penelitian menggunakan RAL: 6 perlakuan 5 ulangan, ulangan: 3 ekor ayam SenSi-1 Agrinak. Perlakuan pakan penelitian: P0 (kontrol), P1 = BIS 40% , P2 = BIS 30% + BISF 10%, P3 = BIS 20% + BISF 20%, P4 = BIS 10% + BISF 30%, P5 = BISF 40%. Pakan perlakuan diberikan pada ayam umur 10 hari sampai 10 minggu, kemudian dilakukan penyembelihan untuk pengamatan bobot potong, bobot karkas, potongan komersil dan persentase karkas (dada, sayap, punggung, paha atas, paha bawah) serta kualitas daging. Hasil penelitian menunjukkan bahwa penggunaan BISF 30% + BIS 10% dalam pakan mampu meningkatkan bobot potong, bobot karkas, bobot dada, bobot paha bawah, bobot saya dan menurunkan lemak abdominal, namun tidak menunjukkan hasil yang berbeda terhadap persentase karkas, punggung, dada, paha, dan sayap pada ayam SenSi-1 Agrinak. Penggunaan 40% BISF dalam ransum mampu meningkatkan kandungan protein daging namun tidak menunjukkan hasil yang berbeda terhadap pH, daya ikat air, susut masak, kadar air dan lemak kasar pada ayam SenSi-1 Agrinak. Hal ini menunjukkan bahwa pemberian 30% BISF + 10% BIS dan pemberian 40% BISF layak digunakan dalam ransum ayam SenSi-1 Agrinak.(The effect of use of palm kernel oil at the level of 40% in the ration on slaughter weight, carcass commercial cuts and meat quality SenSi-1 Agrinak chicken)ABSTRAK. The study was conducted to determine the effect of optimizing the use of PKM/PKMF in the ration on carcass, carcass components, carcass percentage, meat physical, and chemical quality of SenSi-1 Agrinak chicken. The research feed treatments were: P0 (control), P1 = PKM 40%, P2 = PKM 30% + PKMF 10%, P3 = PKM 20% + PKMF 20%, P4 = PKM 10% + PKMF 30%, P5 = PKMF 40%. The treatment feed was given to chickens aged 10 days to 10 weeks, then slaughtered for observation of slaughter weight, carcass weight, carcass commercial cuts and carcass percentage (breast, wings, back, upper thigh, lower thigh) and meat quality. The results showed that the use of PKMF 30% + PKM 10% in feed was able to increase slaughter weight, carcass weight, chest weight, lower thigh weight, my weight and reduce abdominal fat, but did not show different results on the percentage of carcass, back, chest, thighs, and wings on Sensi-1 Agrinak chicken. The use of 40% PKMF in the ration was able to increase the protein content of meat but did not show different results on pH, water holding capacity, cooking loss, water content and crude fat in Sensi-1 Agrinak chicken. This shows that the provision of PKMF 30% + PKM 10% and the provision of PKMF 40% are suitable for use in the ration of SenSi-1 Agrinak chickens.

Abstract

The use of oil palm fronds (OPF) in cattle diets is limited by their high fiber content and low digestibility. This study evaluated the effects of MOL-fermented OPF supplemented with DL-methionine and L-lysine HCl on the performance, digestibility, and economic efficiency of local crossbred bulls. The study was conducted from March to May 2019 at the Marihat Perkasa Cattle Farm in the Simalungun Regency of North Sumatra, Indonesia. A total of 12 local crossbred bulls aged 12–18 months with an average initial body weight of 211.17 ± 39.04 kg were arranged in a randomized block design with four dietary treatments and three body weight blocks. The rations were formulated as complete feeds containing 45% roughage and 55% concentrate feed. Treatments were as follows: T0 = concentrate + field grass, T1 = concentrate + unfermented OPF, T2 = concentrate + MOL-fermented OPF, and T3 = concentrate + MOL-fermented OPF supplemented with 0.25% DL-methionine and 0.25% L-lysine HCl based on the total ration as-formulated basis. For T2 and T3, OPF was anaerobically fermented for seven days using 300 mL MOL inoculum per 50 kg fresh OPF, with 1% urea and 4% molasses. The cattle were adapted to the diets for two weeks before data collection, followed by a 60-day feeding trial. Dietary treatment significantly affected all variables (P<0.05). T3 produced the highest feed intake (7.48 ± 0.316 kg/head/day), average daily gain (1.27 ± 0.205 kg/head/day), dry matter digestibility (72.23 ± 6.58%), organic matter digestibility (73.65 ± 6.26%), and income over feed cost (1,438,012 IDR/head), as well as the lowest feed conversion ratio (8.61 ± 1.03). In conclusion, MOL-fermented OPF supplemented with 0.25% DL-methionine and 0.25% L-lysine HCl improved the performance, digestibility, and economic efficiency of local crossbred bulls.
