Embodiment

[0057] Abalone were divided into four different groups, one of which was fed to standard of the control group. The other three groups were fed with different amounts of L-proline In the fish farm-based feeding trial, four groups of abalone were used. Commercial abalone farmers provided approximately 1000 test animals. Since no previous studies were available, an exponentially different L-proline concentration was chosen.

[0058] image 3 The growth of the four groups of animals fed the different diets for 3 months is described. Animals were weighed and measured prior to the start of the feeding trial and at the end of the trial. There was no significant difference in growth between the different groups, indicating increased L-proline There were no negative effects on animal growth, and the increased feed was palatable and easily accepted by the animals. There were 120 animals per group at the beginning of the first month and 30 animals per group at the end of the th...

Abstract

This invention relates to the use of free L-proline in the preparation of a supplement, and to a supplement so prepared, as well as a method using such a supplement for supplementing the concentration of cellular free L-proline in abalone and for restricting the dehydration of abalone. The supplement is further effective in reducing the levels of free radicals in abalone experiencing water stress and hypoxic stress. The invention further relates to a method of restricting the dehydration of abalone during storage and transportation including the step of administering to abalone an effective amount of free L-proline.

Description

technical field [0001] The present invention relates to amino acids and the use of amino acid supplements thereof. The present invention further relates to an abalone feed and anti-dehydration supplement comprising the amino acid. Background technique [0002] In South Africa, South African abalone (Haliotis midae) has been successfully grown commercially in land-based growing systems. Investment in the South African abalone farming industry exceeds R80,000,000, driven by seemingly unsatisfied foreign markets and favorable exchange rates enjoyed by exporters. [0003] The current production of the 11 largest commercial farms totals about 780 tonnes per year and the raw material is earmarked for the Far East market. At US$37 per kg (including casing), this equates to around R200,000,000 in foreign exchange earnings per year. Besides the huge foreign exchange earnings, another advantage of farming abalone is that it relieves the pressure on the limited and slow-growing natu...
