“…Amino acid contents in rabbit meat were determined according to the method of Luo et al (2017) with minor modifications. Rabbit meat samples were hydrolysed with 10 mL of 6 mol L À1 hydrochloric acid (HCl) in a vacuum at 110 C for 24 h. The hydrolysates were taken out of the oven, cooled down, and then diluted with ultrapure water in a 50-mL volumetric flask.…”

To determine the protein profile of rabbit meat, the protein composition in meat of rabbits with different breeds and ages was investigated. In this article, M. Longissimus thoracis et lumborum (LTL) samples were obtained from six groups (ten rabbits in each group) of 60 female rabbits (Ira and Sichuan white; 35, 70, and 105 days old). Their nutritional characteristics, amino acid profile, protein quantity, and protein profile were analysed. The results showed that rabbit meat contained high content of essential amino acids, especially for Lys (2.26%). The analysis of amino acid profile in rabbit meat indicated that it varied significantly with rabbit breeds and ages. The proportion of stromal protein to total protein in rabbit meat was significantly influenced by age (p < .05), and the mean proportions of sarcoplasmic, myofibrillar, and stromal protein to total protein in rabbit meat were 32.57%, 57.20% and 10.23%, respectively. A total of 835 proteins were identified from the samples using shotgun proteomics. These proteins were mainly involved in energy metabolism, material transport and biochemical reactions, and the highest number of proteins was observed in meat of 35-day-old rabbit (p < .05). Although breed had a limited influence on the number of proteins in rabbit meat (p > .05), 69 and 35 unique proteins were identified in Ira and Sichuan white, respectively. In conclusion, both breed and age can affect the protein profile of rabbit meat, and the difference in protein profile may be the reason for the quality variation of different rabbit meat samples. HIGHLIGHTS Comparing the differences between two rabbit breeds from the perspective of proteome. Elucidate proteome in rabbit muscle during its growth. The outcome means that a total of 835 proteins were identified from the samples using shotgun proteomics, and the highest number of unique proteins was observed in meat of 35-day-old rabbit.

“…Raw materials used in feeds are expected not only to be a source of protein that provides better growth, but they are also expected to provide features such as enhanced reproduction, disease protection, environmental stress resistance, better coloration and delicious meat. In this regard, it has been previously reported by Luo, et al [69] that the hemocyanin and its functional units from veined Rapa whelk showed phenol oxidase activity [70,71], antimicrobial activity [70,72], antiviral activity [73], antitumor activity [74,75] and healing properties on skin burns [76].…”

A Potential Substitute to Fish Meal: The Veined Rapa Whelk, Rapana Venosa

In aquaculture industry, fish meal is considered to be the most important raw material in aquatic feeds, due to high quality and quantity of its protein. The necessity of fish meal has been increasing as the aquaculture industry grows. However, as the rapid growth of aquaculture sector has created a pressure on the sources of fish meal, a decrease in relevant fish populations have been encountered and fish meal price have increased. To date, several raw materials have been therefore investigated in order to replace fish meal in aquafeed and reduce production costs; but yet, not an exact one has been found to completely replace it. Taking into consideration the current situation, any raw material to replace fish meal has been of particular importance. Accordingly, regarding its high protein content and balanced amino acid profile, the veined Rapa whelk meal has been reviewed to replace the fish meal in aquafeeds.

“…After complete drying, the residue was diluted in sodium citrate buffer (pH 2.2) and analysed by an L‐8900 amino acid analyser (Hitachi). The amino acids were identified and quantified based on the standard curves constructed with a mixture of commercially available standards (Luo, Xing, Wang, Peng, & Li, ). All the amino acid standard, including lysine (Lys), methionine (Met), threonine (Thr), isoleucine (Ile), leucine (Leu), valine (Val), phenylalanine (Phe), histidine (His), aspartic acid (Asp), serine (Ser), glutamic acid (Glu), glycine (Gly), alanine (Ala), cysteine (Cys), tyrosine (Tyr), arginine (Arg) and proline (Pro), were purchased from Sigma‐Aldrich.…”

Kesuhong No. 1 with high concentration of astaxanthin was a newly approved aquaculture variety of ridgetail white prawn (Exopalaemon carinicauda) in China, and the information on the nutrient composition and quality evaluation of this new variety is insufficient. Thus, the proximate composition, amino acid and fatty acid profiles were analysed and compared between the new variety and the wild‐typed prawn in the present study, for its better application of the new variety. It showed that there were no significant differences (p > 0.05) of the proximate composition, essential amino acid and saturated fatty acid (SFA) of muscle tissue between the wild‐typed prawn and the new variety. However, for the content of some delicious amino acids (Ala and Tyr), it was significantly higher (p < 0.05) than that in the wild‐typed prawn. Similarly, for some ω3 polyunsaturated fatty acids (ω3 PUFA), such as docosahexaenoic acid (DHA) and eicosapntemacnioc acid (EPA), it was also significantly higher (p < 0.05) than that in the wild‐typed prawn. In addition, higher PUFA/SFA ratio and lower ω6/ω3 ratio also improved muscle quality in the new variety. Information obtained in the present study indicates a promising natural source of ω3 PUFA with high nutritional value, and has strong potential application value in this new variety of E. carinicauda.
