Abstract

Standard of nutrient requirements especially amino acid requirements in kampung chicken’s diet was not known yet. Therefore, until now formulation of kampung chicken’s diet still refferenced to nutrient requirements of laying hen. Usualy formulation of kampung chicken was based on protein and metabolizable energy requirement only, without considering about it’s balances of amino acids. Amino acids that usualy deficiency in diet were lysine and methionine. Because, study about amino acid requirement of kampung chicken was limited, so this research was conducted to study effect the suplementation of lysine in kampung chicken diet on body weight, carcass, and carcass quarter of kampung chicken (thigh and breast quarter yield). The experiment was designed by using randomized completely design with 5 treatments of supplementation of lysine (A = 0 % as a control, B = 0.15%, C = 0.30%, D = 0.45%, and E = 0.60%) in diet which crude protein content 14.5% and 2900 kkal/kg ME with 4 replications. Parameters were: body weight, carcass weight, percentage of carcass, thigh weight, breast weight, percentage of thigh, and percentage of breast of kampung chickens. The results showed that suplementation of lysine in diet highly significant (P<0.01) increased the body weight, carcas weight, thigh weight and breast weight. Suplementation of lysine in diet also significant (P<0.05) increased the percentage of breast, but not significant (P>0.05) on persentage of carcas and percentage of thigh. Levels supplementation of lysine bigger than 0.15% in diet (C = 0.30%, D = 0.45%, and E = 0.60%) gave the same effect as at level 0.15%. It concluded, the level of lysine supplementation in kampung chicken diet recomended was 0.15%. Therefor it was known that requirement lysine for kampung chicken on growth periode was 0.77%.

Abstract

Tulisan ini dibuat untuk mengetahui potensi, faktor pembatas, dan pengolahan rumput laut coklat (Phaeophyceae) sebagai pakan ayam petelur. Rumput laut coklat (Phaeophyceae) adalah rumput laut yang mengandung pigmen klorofil a, karotin, xanthofil dan fukosantin, pigmen yang dominan adalah fukosantin yang menutupi warna lainnya dan menyebabkan rumput laut ini kelihatan berwarna coklat. Rumput laut coklat memiliki potensi sebagai bahan pakan ayam petelur karena ketersediaan yang melimpah, tidak bersaing dengan kebutuhan manusia, mengandung zat-zat nutrisi, tidak bersifat toksik, kaya asam lemak omega 3, mengandung pigmen fukosantin, alginat dan fukoidan. Faktor pembatas penggunaan rumput laut ini, yaitu 1) Kandungan nutrisi dan kualitas: alginat tinggi, protein rendah, dan energi rendah; 2) Kandungan anti nutrisi: kadar garam tinggi dan phlorotannin; 3) Penanganan dan pengolahan: membutuhkan berbagai pengolahan khusus sebelum digunakan sebagai pakan ternak. Faktor-faktor pembatas tersebut dapat diatasi dengan perlakuan fisik (pencucian, pengeringan, autoklaf, perebusan dan freezing), fermentasi dan penambahan enzim dalam pakan sebagai upaya untuk meningkatkan ketersediaan zat nutrisi dan mendetoksifikasi senyawa antinutrisi. Rumput laut coklat (Phaeophyceae) memiliki potensi sebagai bahan pakan penyusun ransum ayam petelur.
