This study was conducted to evaluate the possible utilization and the replacing range of fish meal analogue (FMA) as a dietary animal protein source for fish meal replacer in fingerling common carp, Cyprinus carpio. Leather meal, meat and bone meal, feather meal, squid liver powder, poultry by product meal, blood meal and amino acids were selected as ingredients for FMA. fish averaging 12.5 g were fed one of five isonitrogenous and isocaloric diets containing fish meal and/or FMA as the dietary animal protein sources. Fish meal protein (0, 20, 40, 60 or 100%) was replaced by the graded level of FMA protein. The feeding trial was conducted for 12 weeks after one week of conditioning period. Percent weight gain of fish fed diets containing 20%, 40% and 60% FMA were not significantly different from that of the fish fed the control diet (P>0.05). Feed conversion ratio of fish fed diets containing 20%, 40%, 60% and 100% FMA were not significantly different from that of fish fed control diet. These findings suggest that replacement of fish meal protein by FMA could be possible up to 60% of fish meal protein in fingerling Israeli carp diets.

This study examined the partial replacement of the fish meal with meat meal in practical diets for juvenile rock-fish. Five isonitrogenous (48% CP) diets were prepared to contain meat meal at 0% (control), 10%, 20%, 30% and 40% with substituting the mackerel meal in the control diet. Three replicate groups of fish (initial average weight, 4.1g) were hand-fed to visual satiety two times daily for 8 weeks. Survival (>93%) and daily feed intake were not significantly different (P>0.05) among treatments. The best weight gain, feed efficiency and protein efficiency ratio were obtained from fish fed the diets containing 0% and 10% meat meal, and were not significantly different (P>0.05) to those of fish 134 diet containing 20% meat meal. Condition factor, visceralsomatic index and hepatosomatic index were not influenced by dietary meat meal levels. The contents of crude protein and ash of whole body were not significantly affected (P>0.05) by dietary meat meal levels, whereas crude lipid content of fish fed the diets containing 30% and 40% was lower than that of fish fed the control diet. Proximate composition of liver was not influenced by dietary meat meal level (P>0.05). The data obtained in this study indicate that a diet containing $10{\sim}20%$ meat meal could be used for least-cost formulation in juvenile rockfish diet.

This study was conducted to provide basic data for evolving a strategy for the development of Vietnam's customized HMR program and formulating a marketing strategy by analyzing the characteristics and variations of HMR consumption behavior by household size. The results of the analysis were as follows: The number of single households using HMR as a general meal at home was higher than multiple-person households. Moreover, there was a high preference for 'ready to heat' and 'ready to eat' products, which are relatively easy to cook and prepare. It was observed that single households preferred department stores, hypermarkets, and convenience stores for purchasing HMR when compared to multiple households, and that single households preferred to acquire information through TV/radio and internet advertisements. Among the HMR selection attributes, single households valued taste, quantity, price, preparation process, preparation time, and ease of storage as important. Reflecting on the results of this study, when developing HMR in Vietnam, it is necessary to develop a product that can nutritionally replace the general meal with a focus on convenience. In addition, there is a need for products that possess various attributes such as convenience, health, and eco-friendliness.

Mealworm (Tenebrio molitor) was evaluated to investigate the effect of partial or total replacement of fish meal in diets for white shrimp, Litopenaeus vannamei. Experimental groups of shrimp with average initial body weight (2.43 ± 0.54 g) were fed each with 4 isonitrogeneous (38% crude protein) diets formulated to include 0, 25, 50 and 100% (diets 1 to 4, respectively) of fish meal substituted with mealworm. After eight weeks of feeding trials, shrimp fed with diet 3 and 4 revealed the highest values for live weight gain(8.01 ± 2.51 and 7.93 ± 1.12), specific growth rates (2.70 ± 1.12 and 2.59 ± 0.51) as well as better feed conversion ratio (2.69 ± 0.09 and 2.72 ± 0.19) compared to the control group with statistically significant manner (p<0.05). Survival range was 98% in all the treatments. An increase in weight gain and other growth associated parameters was observed with higher replacement. These results clearly indicate that 50% and 100% of fish meal protein in shrimp diet can be replaced by mealworm not only without any adverse effect but also the effect of promoting growth performance.

The digestibility of organic matter (OM), crude protein (CP), ether extract and amino acids of a cassava root meal and rice bran diet, without (Basal) and with inclusion of fish meal (FM) or fresh (FSB) or ensiled (ESB) shrimp by-product in growing pigs (Large White$\times$Mong Cai) fitted with post-valve T-caecum (PVTC) cannulas was studied in a $4{\times}4$ change-over experiment. Significantly higher ileal digestibility of OM in the basal and FM diets and lower ileal digestibility of CP in the basal and ESB diets were found (p<0.05). Total tract digestibilities of OM and CP of diet ESB were lower (p<0.05) than in the other diets. The apparent ileal digestibilities of most amino acids were higher (p<0.05) in diets FM, FSB and ESB than in the basal diet. There was no difference (p>0.05) in the ileal digestibility of individual amino acids between diets FM, FSB and ESB, except for threonine, alanine and glycine. The estimated apparent ileal digestibility of individual amino acids in ensiled shrimp by-product was lower (p<0.05) than in fresh shrimp by-product and fish meal. In conclusion, as a result of the reduced daily intake of the diets containing shrimp by-products and lower ileal and total tract digestibility of both fresh and ensiled shrimp by-products complete replacement of fish meal cannot be recommended. The ensiled shrimp by-product was inferior nutritionally compared with fresh shrimp by-product. However, lower daily feed intakes of both the FSB and ESB diets suggest that the replacement should only be made partially, in order not to reduce the overall performance.

This study examined the customers' perception on Home Meal Replacement (HMR) products. Specifically, there were three research objectives: 1. to identify the customers' HMR purchase patterns and preference of HMR product development; 2. to identify the attributes of the HMR products that the customers perceive; and 3. to examine the customers' level of expectation-confirmation toward HMR product attributes according to the demographic characteristics. This study employed a self-administered survey that was distributed online from November 21~24, 2017. The sample of the study was the customers who had purchased HMR products in the six months prior to taking the survey. A total of 553 respondents completed the survey, which was used for data analysis. The results revealed the customers' HMR purchase patterns. The major HMR product type of purchase was ready to heat (52.6%), while the main reason for purchasing HMR products was convenience (83.2%). For the differences in the level of expectation-confirmation toward HMR products in accordance with the demographic characteristics of customers, the results indicated that there was a difference in the expectation-confirmation level according to age, whereas the respondents aged 29 and under showed a significantly higher level of time-saving for the preparation and ease of cooking (P<0.05) than the other age groups. In addition, there was a significant difference in the expectation-confirmation level for saving meal preparation time (P<0.05) and convenience (P<0.01) among the customer's occupation. These findings can provide the basis for a strategy for developing HMR products reflecting the rapidly changing customers' needs. HMR products should be developed according to the specific target market, as the study indicated that the respective customer segmentation resulted in a difference in their expectation toward HMR products.

The study was conducted to examine the effects of partially replacing soybean meal (SBM) by solid-state fermented cottonseed meal (FCSM) on growth performance, serum biochemical parameters and immune function of broilers. After inoculated with Bacillus subtilis BJ-1 for 48 h, the content of free gossypol in cottonseed meal was decreased from 0.82 to 0.21 g/kg. A total of 600, day-old male yellow-feathered broilers were randomly divided into four groups with three replicates of 50 chicks each. A corn-SBM based control diet was formulated and the experimental diets included 4, 8 or 12% FCSM, replacing SBM. Throughout the experiment, broilers fed 8% FCSM had higher (p<0.05) body weight gain than those fed 0, 4 and 12% FCSM. The feed intake in 8% FCSM group was superior (p<0.05) to other treatments from d 21 to 42. On d 21, the concentration of serum immunoglobin M in the 4% and 8% FCSM groups, as well as the content of complements (C3, C4) in 8% FCSM group were greater (p<0.05) than those in the SBM group. Besides, birds fed 8% FCSM had increased (p<0.05) serum immunoglobin M, immunoglobulin G and complement C4 levels on d 42 compared with bird fed control diet. No differences (p>0.05) were found between treatments regarding the serum biochemical parameters and the relative weights of immune organs. In conclusion, FCSM can be used in broiler diets at up to 12% of the total diet and an appropriate replacement of SBM with FCSM may improve growth performance and immunity in broilers.

A study was conducted to compare the effect of feeding commercial formula ration and corn-soybean meal based rations on growth performance, feed conversion ratio, mortality percentage, dressing percentage, carcass composition and economics of raising broiler chicks at commercial farms. 3000 day old broiler chicks were randomly divided into 4 groups with 3 replicates of 250 birds in each. Four iso-nitrogenous and isocaloric rations (A, B, C and D) were prepared and randomly allotted to each group. Ration A was a commercial broiler ration whereas ration B had the same formula with the exception that all the animal protein sources were replaced with soybean meal (SBM). Ration C was based on only corn and SBM. Ration D contained corn, SBM and 25% fullfat soybean (FFSB). The birds were given the experimental rations starter from day 1 to 28 and finisher from 29 to 49. The results indicated that the birds fed on corn-soybean meal based rations gained significantly figher weights showed better feed conversion ratio, gave higher dressing percentage with better carcass composition, lower mortality and higher net profits as compared to those fed on commercial ration. The replacement of animal protein sources in commercial ration with SBM (ration B) although did not show any significant differences in the performance of birds as compared to ration A, a little improvement was visible indicating that SBM can be used as a good substitute of animal protein sources. Similarly the replacement of SBM with FFSB up to a level of 25% did not affect the broiler performance as compared to only SBM.

This study investigated the effects of replacing fish meal (FM) with a mixture of four protein sources (wheat gluten, soy protein concentrate, tankage meal, and poultry byproduct meal) in an extruded pellet (EP) diet for olive flounder Paralichthys olivaceus. Five experimental diets were formulated with alternative proteins replacing 0%, 20%, 30%, 40%, and 50% of FM. Taurine and betaine were added as attractants in the diets. Triplicate groups of fish (initial body weight: $196{\pm}2g$) were fed the diets to apparent satiation. Over the course of a 6-month feeding trial, there were no significant differences between the groups in growth performance, feed utilization, survival, or villus height. The dry matter and protein digestibility of FM50 diet were significantly lower than those of the control diet at water temperatures below $18.5^{\circ}C$ in months 4 and 6. This is a highly significant first report on FM replacement in an EP diet given to olive flounder over a 6-month-long feeding period. It shows that the proper mixture of protein sources can replace up to 50% of FM in olive flounder EP diets with taurine and betaine supplementation. It also shows that 40% of FM could be safely replaced in EP diets during periods of low water temperature.

To study the effects of partial replacement of soybean meal (SBM) with palm kernel meal (PKM) and copra meal (CM) on growth performance, nutrient digestibility and carcass characteristics in finishing pigs, a total of 150 crossbred pigs (Landrace$\times$Duroc$\times$Yorkshire; average $52.11{\pm}1.08kg$ body weight) were alloted to five treatments, in a randomized block design. The treatments included 1) Control: without PKM or CM, 2) PKM2: 2% of palm kernel meal, 3) PKM4: 4% palm kernel meal, 4) CM2: 2% of copra meal, 5) CM4: 4% of copra meal. During the early finishing period (52~74 kg), growth performance was better in CM diets than in PKM diets or control diet, and in overall period (74~100 was lower (p<0.05) in PKM4 diet than the other diets. Nutrient digestibilies of PKM or CM substituted diets showed the tendency to be lower than those of control diet. In the early finishing period, total amino acid digestibilities of PKM and CM diets had the tendency to be lower than control diet, and in the late finishing period, they were lower (p<0.05) than control diet. Carcass length was longer (p<0.05) in the pigs fed 2% CM than in the pigs fed 4% PKM diet, but other carcass characteristics were not different among treatments. Although the dietary C14:0 content affected (p<0.05) on the C14:0 content in the carcass, the inclusion of PKM or CM in the diet did not affect the total saturated fatty acids and unsaturated fatty acids in the backfat of finishing pigs. Although it was not significant, supplementation of CM at the 2% and 4% of control group tended to decrease feed cost per kg weight gain by 2.89 to 1.42%, respectively. In conclusion, copra meal can be a valuable source of protein in the diet for finishing pigs and may replace other protein sources in pig diets to a considerable extent.
