The effect of complete feed to carcass characteristics and meat quality of male Bali cattle fattened in West Timor, Indonesia

Abstract

Aim: This research aimed to know the effect of the use of complete feed on Bali cattle fattening performance seen from the carcass characteristics. Materials and Methods: The cattle employed in this research were 12 male Bali cattle aged between 2 and 2.5 years old based on the teeth estimation. The average initial body weight of the cattle during the research was 181.50±16.51 kg. The complete feed contained Gliricidia sepium, natural grass, ground corn, bran pollard, and rice bran which have been compiled into three types of ration of T1, T2, and T3. The T1 ration contained standard crude protein (CP) and high energy (11% CP; 72% total digestible nutrient [TDN]), and T2 contained medium protein and high energy (13% CP; 72% TDN), while T3 ration contained high protein and high energy (%15 CP; 72% TDN). Results: The meat percentage of T2 and T3 was relatively the same, but higher than T1 (p<0.05). The bone percentage and meat: A bone ratio of T2 was higher than T1; in contrast, and T3 was relatively the same with T2 and T1 (p<0.05). The weight of slaughter, carcass percentage, and weight of meat, bone, and fat were relatively the same among the treatments. Conclusion: The application of complete feed with protein source from G. sepium with CP and TDN of 13 and 72%, respectively, can improve carcass percentage and meat: A bone ratio of male Bali cattle fattening. The treatments have not had a positive effect on slaughter weight (kg), hot and cool carcass weight (kg), meat and fat weight (kg), fat percentage, and non-carcass (kg).

Estimasi Kadar Air Daging Sapi Berdasarkan Luas Area Jejak Air Daging Fresh Meat Water Estimate Based On Meat Water Stain Area

“…Jumlah air bebas yang lebih banyak akan menimbulkan luas jejak air yang ditimbulkan akan lebih luas. Daging yang digunakan dalam penelitian ini Kadar air tidak dipengaruhi secara nyata oleh perbedaan perlakuan pakan pada daging sapi Bali jantan yang secara normal berkisar antara72,76%-73,32% (Tahuk et al, 2020) hal ini masih dalam rentang yang dinyatakan Suparno, (2015). Berdasarkan perhitungan yang disusun dalam Tabel 4, apabila ada sampel daging yang dengan uji tekan dengan beban 2 kg selama 1 menit menunjukkan jejak air pada kertas Whatmann dengan panjang jari-jari >6,76 cm atau luas jejak air >143 cm 2 maka dapat dicurigai sebagai daging gelonggongan karena estimasi kadar air yang diperoleh adalah >80%.…”

Determination of free radical scavenging activity, phenolic and flavonoid content of seven corn cultivars from the Southwest Maluku District, Indonesia

“…Because of this diversity of corn cultivars, it has been successfully used as ready-to-use supplementary food (RUSF) aimed at improving the nutrition of moderate acute malnutrition (MAM) in children under five years old in Indonesia (Fetriyuna et al 2021). Also, the agricultural waste from corn has been used in the country to increase productivity and carcass characteristics of lambs (Purbowati et al 2021) and cattle (Tahuk et al 2020) fed with this fibrous agricultural waste as a substitute for regular grass. Furthermore, the use of corn to produce biodiesel for the United States market has caused changes in land use for cultivating corn in Malaysia and Indonesia, compared to other vegetables like soy (Taheripour and Tyner 2020).…”
