Replacement of Fishmeal by Poultry By-Product Meal in Formulated Diets for Growing Hatchery–Reared Juvenile Spotted Babylon (Babylonia areolata)

Abstract

A feeding trial was conducted to evaluate the effects of five levels of partial to total replacement of fishmeal by poultry by-product meal on growth performance and body composition of hatchery-reared juvenile spotted babylon (Babylonia areolata) under aflow-through culture system over 150 days. Five experimental diets were formulated to contain 0%, 25% 50%, 75% and 100% of gradient poultry by-product meal (diet PBM0, PBM25, PBM50, PBM75 and PBM100, respectively). Significant differences (P<0.05) in weight gain, specific growth rate, total feed intake, feed conversion ratio, and protein efficiency ratio were found among the feeding treatments, except for final survival rate. Results showed that snails fed diets of PBM25, PBM50, and PBM75 displayed better specific growth rates ranging from 2.19-2.21% day-1 and did not differ significantly (P>0.05) while snails fed diets of PBM0 and PBM100 showed poorer specific growth rates of 2.03-2.12% day-1 , respectively. Final survival rates of the snails ranged from 92.73%-93.94% and did not differ significantly (P>0.05) between feeding treatments. Significant differences (P<0.05) were detected in proximate composition (protein, ash, fat, moisture, and carbohydrate, cholesterol content, amino acid composition and fatty acid composition of the whole flesh of experimental snails among all feeding treatment groups. Snails fed diets of PBM-50 resulted in the highest protein and fat contents compared with snails fed the PBM0, PBM25, PBM75 and PBM100 replacement diets. Cholesterol was significantly lower (P<0.05) in snails fed diets of PBM75 and PBM100 than in snails fed diets PBM0, PBM25, and PBM50. The whole body composition of snails fed diet of PBM75 was significantly higher (P<0.05) in total non-essential amino acids and total essential amino acids than those of snails fed PBM0, PBM25, PBM100, and PBM75. The whole body composition of snails fed PMB-50 was significantly higher (P<0.05) regarding EPA, DHA, ARA, n-6 PUFA, and n-3 PUFA contents than those of snails fed PBM0, PBM25, PBM100, and PBM75. The results of this study indicated that poultry by-product meal can replace fishmeal protein by 50-75% with no negative effects in snail growth performance. Moreover, the inclusion of up to 75% poultry by-product meal in the diet improved feed efficiency and body composition.

Growth Performance, Feed Utilization and Body Composition of Clarias gariepinus (Burchell 1822) Fed Marine Fish Viscera-based-diet in Earthen Ponds

“…Fish fed with D30 and D50 showed a significantly greater amount of body lipid and lower ash content, in comparison with those of fish fed coppens and D0. This trend was similar to that related in the earlier studies of Kristsanapuntu et al [76] in red drum, Sciaenops ocellatus, and [32] in catfish Clarias batrachus. According to Luchtman et al [32], the increased body lipid content may be due to increased energy content of diets containing MFV meal, which have a greater fat content ( Table 1).…”

Chicken-based by-products as a main component in African Catfish (Clarias gariepinus) in the environments of Uzbekistan

“…Aquaculture development in the world depends largely on the availability of fish feed: aquafeed for intensive aquaculture is based on fish meal as the main protein source. To achieve a good growth, catfish requires complete artificial feed of 35 -45% protein level [2,11,13]. Fishmeal is a major protein component in formulated aquaculture feeds also for catfishes, its use in African catfish formulated feed is 40 to 60%.…”

“…One of promising species is African catfish (Clarias gariepinus). It is a globally popular cultured fish in Africa, Asia and Europe [11,12]. It is widely cultured infreshwater ponds, tanks.…”

Responsible Fishmeal Consumption and Alternatives in the Face of Climate Changes

“…Previous studies concluded that animal protein components can be valuable for fish feed formulation. They are rather much less expensive than fish meal (Hernandez et al, 2014;Sierra et al, 2014;Kritsanapuntu and Chaitanawisuti, 2015;Yu et al, 2015;Yones and Metwalli, 2015).…”
