Pengaruh Pemberian Pakan dengan Sumber Protein Berbeda terhadap Persentase Potongan Karkas dan Massa Protein Daging Ayam Lokal Persilangan

Abstract

ABSTRAKTujuan dari penelitian ini adalah mengetahui pengaruh pemberian pakan dengan sumber protein berbeda terhadap persentase potongan karkas dan massa protein daging ayam lokal persilangan. Materi yang digunakan adalah 126 ekor ayam lokal persilangan (unsexed) umur2 minggu dengan bobot badan 129 ± 6,34 g. Bahan pakan yang digunakan yaitu jagung, bekatul, bungkil kedelai, tepung ikan, MBM (Meat bone meal) dan PMM (Poultry meat meal). Rancangan percobaan yang digunakan adalah RAL (Rancangan acak lengkap) dengan 3 perlakuan dan 7 ulangan. Perlakuan yang diberikan yaitu T1 = 2 sumber protein (tepung ikan dan bungkil kedelai), T2 = 3 sumber protein (tepung ikan, bungkil kedelai, dan MBM), T3 = 4 sumber protein (tepung ikan, bungkil kedelai, MBM dan PMM). Pemberian pakan menggunakan metode bebas memilih dan perlakuan dimulai pada umur 2 minggu sampai 10 minggu. Parameter yang diamati adalah bobot akhir, bobot potongan karkas, persentase potongan karkas dan massa protein daging. Data yang diperoleh dianalisis ragam dengan uji F dengan taraf 5% dan pada penelitian ini terdapat pengaruh perlakuan sehingga dilanjutkan dengan uji jarak berganda duncan. Hasil penelitian menunjukkan bahwa pemberian pakan dengan sumber protein berbeda berpengaruh nyata (P<0,05) terhadap bobot akhir, bobot potongan karkas dan massa protein daging serta tidak berpengaruh nyata (P>0,05) terhadap persentase potongan karkas. Kesimpulan penelitian ini adalah pemberian pakan dengan sumber protein yang semakin beragam dapat meningkatkan bobot akhir, bobot potongan karkas dan massa protein daging serta memberikan hasil yang sama pada persentase potongan karkas ayam lokal persilangan.

Evaluation of Dry Matter, Organic Matter and Crude Protein Digestibility in New Zealand White Rabbits with Different Sludge Percentages

“…Waly et al (2021) added that better absorption of nutrients has a positive effect on the level of digestibility. Digestibility is closely related to feed consumption, where livestock that have a higher consumption rate may hoard more protein as a form of growth response that is useful for carcass formation (Pratiwi et al, 2017).…”

The Use of Marine Mushroom Extract (Nodulisporium sp.) as Feed Additive in the Ration of Native Chickens on Protein Utilisation Ratio

“…Then the results of this study were higher than the results of research from [17] which showed the value of protein consumption in native chickens reared for 10 weeks from the age of 0 -10 weeks ranged from 23.17 -35.77 (grams/head/week), and the results of research by [14] which where the value of protein consumption of native chickens reared for 10 weeks (age 10 -20 weeks) ranged from 56.28 -79.38 (grams/head/week). High protein consumption is also followed by high protein intake, which results in higher protein to be used in the formation of meat for livestock [18].…”

“…Therefore, the government issued a ban on the use of antibiotics as Agent Growth Prometer or AGP to boost the growth of poultry livestock which has been regulated in Law No. 18 Therefore, it is necessary to find feed additives or feed additives that have active compounds in naturally promoting growth and improving performance in native chickens. One of the feeds that has active compounds in it is the marine fungus Nodulisporium sp.…”

“…This is likely to cause a tendency to increase the cutting weight. The protein content in the ration is used for tissue growth and production and is part of the enzyme structure, so that protein is known as one of the main constituents of body cells and tissues [18].…”
