Effect of a feeding stimulant on feeding adaptation of gibel carp Carassius auratus gibelio (Bloch), fed diets with replacement of fish meal by meat and bone meal

Abstract

The objectives of the study were to investigate the effect of a feeding stimulant on feeding adaptation of gibel carp (Carassius auratus gibelio Bloch) fed diets with replacement of ¢sh meal by meat and bone meal (MBM), and whether or not the juvenile gibel carp could adapt to higher MBM level in the diet. Juvenile and adult gibel carp were tested. Two and one replacement levels were used for juvenile and adult ¢sh respectively. Each group of diets was set as two types with or without a unique rare earth oxide: Y 2 O 3 , Yb 2 O 3 , La 2 O 3 , Sm 2 O 3 , Nd 2 O 3 or Gd 2 O 3 (only the ¢rst four rare earth oxides were used in adult diets) for four adaptation periods of 3,7,14 and 28 days respectively. After mixing, an equal mixture of all six diets for juvenile or four diets for adult was o¡ered in excess for 2 days. During the last 2 days of each experiment, no feed was o¡ered and faeces from each tank were collected. Feeding preference was expressed as relative feed intake of each diet, which was estimated based on the relative concentration of each marker in the faeces.Given some adaptation period, such as 3^28 days, the e¡ects of MBM and squid extract inclusion on the preference to each diet were reduced. After 28 days adaptation, the preferences between groups were not signi¢cantly di¡erent.

Meat and bone meal replacement in diets for juvenile gibel carp (Carassius auratus gibelio): effects on growth performance, phosphorus and nitrogen loading

“…However, the palatability of MBM in the present work was not as good as those used by Robaina et al (1997) and Yang et al (2004). (3) Research has shown that nutrient utilization can be improved by combining different animal and plant protein sources (Bureau et al 2000;Webster et al 2000;Coyle et al 2004;Xue et al 2004). Generally, the inclusion of MBM at levels above 5% of the diet is not recommended (Kureshy et al 2000).…”

Replacement of fish meal with blend of rendered animal protein in diets for Siberian sturgeon (Acipenser baerii Brandt), results in performance equal to fish meal fed fish

“…2006; Tibbetts et al. 2006), poorer amino acids profiles and palatability (Xue et al. 2004; Shapawi et al.…”

“…The limitations for most alternative proteins were lower digestibility (Luo et al 2006;Tibbetts et al 2006), poorer amino acids profiles and palatability (Xue et al 2004;Shapawi et al 2007). Rendered by-products from slaughter houses, such as MBM, PBM, BM and HFM have been successfully used in feeds for various fish species.…”

The effect of different dietary iron levels on growth and hepatic iron concentration in juvenile gibel carp (Carassius auratus gibelio)

“…Because of a higher growth rate it has almost replaced the crucian carp in current aquaculture in China. The nutritional studies of this fish have been widely conducted in our laboratory (Pei and Xie, 2004; Xue et al., 2004; Yang et al., 2004). However, the effects of dietary iron concentration on juvenile gibel carp have not yet been reported.…”
