This study investigated the morphological characteristics, and chemical composition of Archachatina marginata (African Giant Land Snail) reared on Quail droppings meal (QDM.) substituted for protein sources in snail feed. Five trial snail feeds (Diet I-V) were fed to fifty snails (average weight 157.3 g) for 12 weeks. The morphological characteristics of the snail and its flesh and haemolymph chemical composition were determined using standard methods. There was an appreciable increase in the growth parameters (weight, shell width and shell length) across the treatment groups. The feed conversion ratio (FCR) ranges from 2.74 to 3.75, and snails served Diet I gave the highest FCR. The result of the proximate analysis revealed that snail flesh possessed a higher amount of protein, fat, ash, fibre and energy except carbohydrate than hemolymph. Increasing QDM in the diets increased the proximate contents of the snail's flesh and hemolymph, except fat and fibre. The minerals found in all the treatments are not toxic, and snails fed diet V possessed the highest mineral contents (sodium, potassium, calcium, magnesium, iron and phosphorus). The result showed that diet V resulted in the best morphological parameters and feed utilisation of A. marginata snail. Substituting protein sources with QDM in snail feed improved the nutritional quality of snails, reducing the cost of the compounded ration.

Carcass Parameters

A 56-day study was carried out to evaluate the carcass characteristics and organ proportions of broiler chickens fed sorghum-based diets with varying plant protein. A total of 120 day-old broiler chickens from a reputable and disease free farm were used for this study. There were four treatments, each having thirty broiler birds replicated thrice with ten broiler birds per replicate using a Completely Randomized Design (CRD). The broiler birds were offered feed and water ad libitum. The growth parameters were taken on weekly basis. Carcass evaluation was carried out at the end of the trial. One bird per replicate was randomly selected, fasted over-night and slaughtered by severing the jugular vein. After scalding in warm water for about a minute, the feathers were manually plucked, each bird was cut into parts for carcass evaluation. The relative weights of the cut parts were as a percentage of dressed weight. The internal organs, such as heart, kidney, gizzard/proventriculus were all weighed separately and recorded using electric micrometer (3000g weighing gauge). The findings from this study showed that all the carcass parameters considered showed significant differences (p<0.05). Birds fed diet 3 gave the best live weight, slaughtered weight, defeathered weight, dressed weight and commensurate cut-parts. Soybean (whether cake or full-fat) demonstrate superiority over groundnut cake and cashew nut cake. Birds fed diet 3 gave the highest value of thigh, breast -cut, drumstick and wings, while birds fed diets 2, 1 and 4 gave less. The organ proportions of broiler chickens fed different dietary plant sources have all the parameters significantly difference (p<0.05), except the lungs though without any definite pattern. Average weight gain and feed conversion ratio were better (p<0.05) among birds fed diet 2, and 3. Cost benefits analysis per kilogram in naira terms for birds fed different plant protein sources in a sorghum-based diets were significant (p<0.05) among treatment levels. Least cost per kg feed was obtained in diet 1 (p<0.05). Cost of weight gained was (p<0.05) low in T1. Cost of feed consumed was low for diet T1 and T3. Revenue, gross margin and cost benefit ratio estimated were found to high (p<0.05) among T2 and T3. Broiler chickens fed diet 3 gave the best parameters. The actual contributions of the experiment, is to alternatively replace corn with sorghum completely at least cost with optimum performance.

Four isonitrogenous (gross protein content 32%) and isoenergetic (gross energy content 4 080 kcal/kg) diets were prepared by extrusion to investigate the effects of different cereal grains (barley &ndash; diet A, wheat &ndash; diet B, triticale &ndash; diet C, rye &ndash; diet D) as carbohydrate compounds of extruded feeds for carp. The physical and chemical properties of the feeds were established. A 60-day growth test was performed in experimental ponds of 40 m<sup>2</sup> area. Each diet was fed to three groups of fish (initial average weight 200 &plusmn; 10 g). The following rearing effectiveness indices were used in the final evaluation of the growth test: weight gain (WG, %), specific growth rate (SGR, %/d), food conversion ratio (FCR), protein efficiency ratio (PER) and protein retention (PR, %). Conclusions were based on statistical analysis using the Statistica 5.0 package. The results obtained in the growth test did not show any differences in the evaluated feeds regarding their usefulness in the nutrition of carp (there were no statistically significant differences in the values of fish rearing parameters, P &le; 0.05). The recorded growth parameters of carp were as follows: WG: 308.48&ndash;324.0%; SGR: 2.81&ndash;2.92%/d; the feed conversion coefficients were: FCR: 1.43&ndash;1.50; PER: 1.75&ndash;1.83; PR: 29.54&ndash;31.72%. &nbsp;

Fingerlings of Barbodes carnaticus (Jerdon 1849) (6.40±0.267 cm, 2.46±0.39 g) were reared in aerated plastic tubs (40 l) with five iso-energetic diets formulated to contain crude protein levels ranging from 25 to 45% using pure ingredients. Initially, the diet was fed at @5% of the biomass and gradually adjusted based on daily feed consumption. The fish were allowed to feed for 6 h and thereafter the unconsumed feeds were siphoned out. The following day, faecal matter was collected from each tank by filtering the water with a fine meshed nylon cloth (15 μm), dried, pooled and stored for proximate analysis. Water from eachtub was replaced with 50% freshwater every day after faecal matter collection. The feeding trial was conducted for a period of 60 days. Proximate composition of feed and faecal matter was analysed. Acid insoluble ash was used as the reference marker for dry matter, protein and fat digestibility determination. The growth parameters and protein efficiency ratio (PER) were higher (p<0.05) in fish fed 35% protein diet compared to other diets. The feed conversion ratio (FCR) was lower (p<0.05) in 35, 40 and 45% protein diets compared to the lower protein diets. The carcass proximate composition revealed the lowest moisture (p<0.05) and highest protein (p>0.05) and fat content (p<0.05) in fish fed 35% protein diet compared to other diets. The digestibility ofdry matter and nutrients was higher (p<0.05) with 35% protein diet. The study revealed crude protein requirement of 35% by the fingerlings of B. carnaticus.

The aim of this study was to determine the growth parameters of European Flounder fry (Platichthys flesus luscus L. 1758) caught from the nature in different feeding methods in aquaculture conditions. The study was conducted between April and July 2011, and the fish were collected at the connection point of Sarıkum Lagoon with the Black Sea in Sinop Province using seines and large scoops. A total of 750 European Flounder with the average weight of 0.93±0.01 (0.71-1.21) g were stocked in 5 groups with 3 repetitions. The groups were organized according to the feeding protocols [G1:90 days Chironomid larvae (CL), G2:60 days CL+30 days CL+ granular feed (GY), G3:30 days CL+60 days CL+ GY, G4:90 days CL+GY, G5:90 days GY]. At the end of the study, the weights of the fish were determined as 10.83±0.51, 9.89±0.22, 6.33±0.21, 5.13±0.11, 3.81±0.09, respectively. It was found that feeding preferences of the fish had significant effects on weight gain, specific growth rate, feed conversion ratio and survival rate. European Flounder fry, as in their natural habitat, mostly preferred natural feed moving in the deep in the production site. It was determined that using live feed as the starter feed for the adaptation of European Flounder fry had a significant effect on growth parameters and survival rates.

The expansion in the market of ornamental fish depends on the intensification of production systems and the generation of appropriate technologies. Therefore, it is necessary to know the nutritional requirements of each species for the formulation of nutritionally balanced diets. A 30-day feeding trial was undertaken to evaluate the effects of different dietary digestible protein to energy ratio in diets for Betta splendens fingerlings. Fifty-six all-male B. splendens with 1.03 ± 0.11 g average weight were randomly stocked into 56 1L-aquaria in a completely randomized design with a 2 x 4 factorial arrangement, comprising eight treatments and seven replication. Each fish was considered an experimental unit. Diets were formulated to contain 28.0, 35.0, 42.0 and 49.0% DP and 3,600 and 3,200 kcal/kg DE. The growth parameters evaluated in this trial were weight gain (WG), feed intake (FI), feed conversion ratio (FCR), protein efficiency ratio (PER) and specific growth rate (SGR). No difference (P > 0.05) was observed for WG, FCR and SGR. However, a higher FI was observed for fish fed diets containing 42.0% DP (P < 0.05). A positive effect of DP and DE on PER was observed in this study. Generally, according to the increase of DE levels, a reduction on PER was observed. Based on this experimental condition, we recommend the use of 28.0% DP and 3,200 kcal/kg DE in diets for B. splendens.

CHEMICAL COMPOSITION AND ORGANOLEPTIC CHARACTERISTICS OF PROCESSING BAT (Pteropus alecto) FRESH MEAT. Study was done to evaluate chemical composition and preference degree of the consumers on the processing bat meat compared with beef, chicken and cakalang fish using steam cooking method, flavor cooking and spicy cooking method. Chemical composition was analyzed by proximate analysis using procedures of the Association of Official Analytical Chemists. The organoleptic test was done by hedonic test. Data of the hedonic test were analyzed using Kruskal-Wallis method. To evaluate data distribution of the panelist respons on the sample test, the data were using plot graphic box. The hedonic scales were using 1 to 7. The variables used were including color, taste, flavor, tenderness and general acceptance. Results of proximate analyses of bat meat based on fresh meat indicated that water content was 67.21 percents and protein was 20.48 percents. Based on dry matter, the protein contents of bat meat, pork, chicken, and cakalang fish were 48.97 percents, 69.08 percents, 67.14 percents, and 69.41 percents, respectively. The water contents were 5.76 percents, 9.92 percents, 8.27 percents, and 9.90 percents, repsectively; the calcium (Ca) contents were also 10.62 percents, 1.09 percents, 1.36 percents, 1.38 percents, respectively; while Phosphor (P) contents were 1.46 percents, 0.69 percents, 0.66 percents, and 0.72 percents, respectively. Variance analysis for organoleptic test showed that meat type with different processing affected significantly on taste, color, flavor, tenderness and general preference of bat meat, beef meat, chicken meat and cakalang fish by steam cooking, chicken flavor, and spicy cooking methods. Conclusion, bat meat contained protein relatively lower than that in pork meat, chicken meat, and cakalang fish, but mineral contents were relative higher. Results of organoleptic test showed that preference degree of processing meat were higher on using spicy flavor. The specific test on taste, color, flavor, tenderness and general responsed showed relatively the same responses by the panelists.   Key word: Chemical composition, organoleptic test, processing bat meat

Fishmeal is the main source of dietary protein for most commercially farmed fish species. However, fishmeal prices have been raised even further because of competition with domestic animals, shortage in world fishmeal supply, and increased demand. Increased fishmeal prices have contributed to the quest for alternatives necessary to replace fishmeal as a global research priority. A literature search was conducted using these terms on Google Scholar and EBSCOhost; fishmeal replacement in fish feeds, fishmeal alternatives in fish feeds, animal protein sources in aquaculture, insects in fish feeds, terrestrial by-products, and fishery by-products. To calculate the variation between experiments, a random effect model was used. Results indicated that different fish species, sizes, and inclusion levels were used in the various studies and showed that the use of insects, terrestrial by-products, and fishery by-products has some limitations. Despite these drawbacks, the use of animal protein sources as a replacement for fishmeal in fish diets has had a positive impact on the feed conversion ratio, variable growth rate, final weight, and survival rate of different types of fish species of different size groups. Findings also showed that some animal by-products had not been assessed as a protein source in aquaculture or animal feeds, and future studies are recommended.

Modern commercial pig production is a complex process that requires successful producers to understand and resolve factors associated with perturbations in production. One important perturbation is inventory loss due to mortality. In this study, data on 60 lots of approximately 2000 weaned pigs (n = 115,213) from one commercial production system were collected through the wean-to-finish (WTF) cycle with the objective of establishing patterns of mortality, estimating differences in profit/loss among patterns of mortality, and identifying production practices associated with mortality patterns. Information provided by the production system included the number of pigs in each lot at the time of placement (beginning inventory), weaning weight, barn dimensions, number of dead pigs (NDP) daily, capacity placed (proportion pigs actually placed versus what had been planned to be placed) and average weight sold. Analysis of NDP revealed three mortality patterns (clusters I, II, III) composed of 6, 40, and 14 lots, respectively, that differed in the temporal onset and/or level of mortality. Average daily gain (ADG) and feed conversion ratio (FCR) were calculated by growth phase for each cluster. An economic model showed profit differences among clusters due to poor biological performance by clusters I and III in the late finishing phase. Cluster II (n = 40) had fewer dead pigs and the highest profit compared to clusters I (n = 6) and III (n = 14). Area per pig (stocking density) was the only factor associated with the differences in mortality patterns. Routine monitoring and the analysis of mortality patterns for associations with production and management factors can help swine producers improve biological performance and improve profit.
