Abstract

Selenium is a mineral element that acts as an antioxidant and affects enzyme formation, the immune system, and reproduction in livestock. Selenium yeast is an organic form of Se. The high availability of inedible mackerel can be utilized as a raw material for peptone in the growth medium of yeasts that produce organic Se. The objective of this study was to determine the characteristics of pepton derived from inedible mackerel as a growth medium for W. anomalus. Pepton was analyzed for amino acid composition using HPLC, solubility of pepton in water (gravimetric method), pepton yield, pH, proximate analysis, free α-amino nitrogen content, total nitrogen, AN/TN ratio, and salt content (Volhard method). Mackerel fish pepton has the following characteristics: protein content 75.5%, free α-amino nitrogen 1.9%, solubility 99.9%, total nitrogen 12.1%, salt content 7.9%, AN/TN ratio 16.2%, and pH 7.0. Mackerel fish pepton unfit for consumption applied to the growth medium of Wickerhamomyces anomalus as Se-Yeast has a higher growth rate compared to commercial pepton.

Abstract

The purpose of this study was to evaluate the performance of prolific lambs fed milk replacer derived from mackerel peptone with prolific lambs fed mother’s milk. This study used six twin born lambs aged 1 week with an average birth weight of ± 2.05 kg and male. The treatments applied in this study were mother’s milk (P0) and milk replacer containing 100% mackerel peptone (P1). The observed variables included ash content, crude protein content, crude fat content, calcium content, phosphorus content, total nitrogen, total volatile base (TVB) content, milk amino acid profile, milk consumption, body weight gain, feed conversion rate, and mortality. The results showed that milk replacer containing 100% mackerel peptone had high crude protein content and complete amino acid composition. Prolific lambs fed with milk replacers showed no significant difference in body weight gain compared to those suckling from their mothers. Additionally, lambs receiving the milk replacer did not exhibit any signs of digestive disorders, loss of appetite, abnormal behavior, or mortality during the maintenance period. Utilization of mackerel peptone as an alternative protein source can be used up to 100% in milk replacer. It can be concluded that feeding milk replacers formulated with mackerel peptone resulted in a 1.30% increase in lamb body weight, with no significant difference observed in performance compared to lambs suckling form their mothers.
