Kandungan Lemak, Koesterol dan Profile Asam-asam Lemak Daging Kerbau Yang Disuplementasi Pakan Campuran Garam Karboksilat Kering

Abstract

Penelitian bertujuan untuk mengkaji pengaruh suplementasi campuran garam karboksilat kering (CGKK) yang berasal dari minyak ikan terhadap kandungan lemak, kolesterol dan profil asam-asam lemak daging kerbau. Daging berasal dari kerbau jantan umur 1,5-2 tahun yang dipelihara secara intensif selama 2,5 bulan dengan pemberian pakan hijauan 35% dan konsentrat 65%. Suplementasi CGKK berbahan dasar minyak ikan lemuru ditambahkan sebanyak 45 g/kg konsentrat. Setelah pemeliharaan ternak dipotong. Untuk analisa daging digunakan otot longissimus dorsi. Penelitian menggunakan rancangan acak lengkap apabila ada perbedaan di uji'dengan uji lanjut Least Square MeansModels (LSMEAN). Hasil penelitian memperlihatkan bahwa suplementasi CGKK menurunkan kandungan asam-asam lemak jenuh daging kerbau dan meningkatkan kandungan asam-asam lemak tak jenuh daging kerbau. Dapat disimpulkan bahwa suplementasi CGKK meningkatkan profil asam-asam lemak tak jenuh terutama asam lemak omega-3 yaitu EPA dan DHA.

Production and carcass quality of thin-tailed sheep fed diets containing protected and unprotected soybean groats

“…The appearance of rib eye muscle area can give an idea of the carcass produced. This is in accordance with [30] explain that the rib eye muscle area describes the proportion of meat in the carcass, namely the wider the rib eye muscle area the greater the proportion of meat in the carcass. Giving formaldehyde-protected soybean groats up to 10% level has not been able to improve the rib eye muscle area.…”

Effects of waste-based concentrates from broiler farm on physico-chemical qualities and blood profile of landrace pigs

“…Eighty percent of cholesterol is produced in the body, and 20% comes from feed [29 , 34] . High and low levels of cholesterol in the blood are affected by several factors, such as type of feed, livestock, genetics, sex, and age of livestock [30] . Increased cholesterol in the blood, apart from affecting health risks, also affects the quality of the meat produced from these livestock.…”

“…The addition of 10% rejected milk to the CP-550 commercial ration of male pigs after weaning resulted in cholesterol levels of 70.22 mg/dl, HDL of 30.44 mg/dl, and LDL of 23.64 mg/dl, but the TGs level was higher, namely, 92.33 mg/dl. This difference is due to the age of the livestock and the rations given [7 , 10 , 30] . The high crude fiber content of the ration causes the feed flow rate to increase in the digestive tract, and cholesterol in the ration will exit through intestinal peristalsis.…”
