Introduction: Tilapias (Family Cichlidae) are among the freshwater fish species suitable for aquaculture and widely cultivated globally because of their fast growth rate, efficient use of natural aquatic foods, propensity to consume a variety of supplementary feeds, omnivorous feeding habits, resistance to disease and handling, ease of reproduction in captivity, and tolerance to wide ranges of environmental conditions Aims: Experiment was conducted to evaluate the growth performance of Oreochromis niloticus fed varying levels of Basella alba leave based diets. Materials and Methods: O. niloticus fingerlings (1.95±0.01g) were randomly selected and distributed into 15 glass tanks at the rate of 15 fish per tank representing five treatments and three replicates. Five diets were formulated to containing (0, 1.0, 1.5, 2.0 and 2.5 g/100kg diets) of B. alba were prepared and fed to the fish for 70 days. Results: The results revealed that weight gain, specific growth rate, feed intake and feed conversion ratio improved progressively up to the inclusion level of 2.0 g/100g of B. alba leave meal and then declined indicating 2.0g/100g B. alba leave meal as the optimum level that can promote the growth performance of the fish. However, 4th degree polynomial regression analysis indicated the optimum level as about 2.1 g/100g diet. It was observed that there was no significant difference in the survival (p > 0.05) of the fish fed diets with different B. alba leave meal. Conclusion: Based on the results obtained from this present study, it could be concluded that 2.0-2.1 g/100kg of B. alba leave can be included in the diets of O. niloticus fingerlings for optimum growth performance.

 This study was done to explore the effect of replacing mustard oilcake by linseed oilcake in feed on the growth performance of Nile Tilapia (Oreochromis niloticus). Mustard oilcake (MOC) was replaced by linseed oil cake (LOC) at three different level 0%, 50% and 100% to prepare three different types of diets. Diets were prepared with about 18% analyzed crude protein content. Fingerlings were kept in three happa with three replications for each diet in completely randomized design (CRD). Fish of average weight 5.31 g were stocked in happa having size 1.5m×1.5m×1.2m. The experimental fish were fed 3% of their body weight per day, once in the morning for five months continuously. No significant difference (p>0.05) in final mean weight, final total weight, average daily weight gain (DWG), survival rate, extrapolated gross fish yield (GFY), extrapolated net fish yield (NFY) and apparent feed conversion ratio (AFCR) among different treatments were observed. Hence, linseed oilcake can be used as the substitute in the feed of tilapia, if it is locally available.  Journal of Institute of Science and Technology, 2017, 22 (1): 10-16

The study of probiotic application as an important rearing strategy was started more than 30 years ago and most of these studies were carried out to increase growth and survival of larvae. Effect of Bifidobacterium animalis PTTC-1631 and B. lactis PTTC-1736 as probiotic supplement has been studied on growth performance and hematological changes on rainbow trout, Oncorhynchus mykiss alevins with initial body weight of 0.583 ± 0.197 g. The commercial diet was supplemented with graded levels of probiotics (1×107, 2×107 and 3×107 CFU g-1 dry feed) to obtain 3 sets of experimental diets (T1, T2, andT3 respectively) and fed four times a day for 60 days. T1 alevin showed the best growth performance in terms of specific growth rate, weight gain, metabolic growth rate, feed conversion ratio and survival rate. The highest red and white blood cell concentrations were noticed in fish fed T2 and T3 diets, respectively, no significant difference was observed in hemoglobin content. T1 showed the significant elevation of serum biochemical parameters and reduction of cortisol level. The results of present study might suggest likely positive effects of probiotic supplements with concentration of 1×107 CFU g-1 dry feed on growth and hematology on rainbow trout alevins.

How to maximize the use of the genetic merits of the high-ranking boars (also called superior ones) is a considerable question in the pig breeding industry, considering the money and time spent on selection. Somatic cell nuclear transfer (SCNT) is one of the potential ways to answer the question, which can be applied to produce clones with genetic resources of superior boar for the production of commercial pigs. For practical application, it is essential to investigate whether the clones and their progeny keep behaving better than the “normal boars”, considering that in vitro culture and transfer manipulation would cause a series of harmful effects to the development of clones. In this study, 59,061 cloned embryos were transferred into 250 recipient sows to produce the clones of superior Pietrain boars. The growth performance of 12 clones and 36 non-clones and the semen quality of 19 clones and 28 non-clones were compared. The reproductive performance of 21 clones and 25 non-clones were also tested. Furthermore, we made a comparison in the growth performance between 466 progeny of the clones and 822 progeny of the non-clones. Our results showed that no significant difference in semen quality and reproductive performance was observed between the clones and the non-clones, although the clones grew slower and exhibited smaller body size than the non-clones. The F1 progeny of the clones showed a greater growth rate than the non-clones. Our results demonstrated through the large animal population showed that SCNT manipulation resulted in a low growth rate and small body size, but the clones could normally produce F1 progeny with excellent growth traits to bring more economic benefits. Therefore, SCNT could be effective in enlarging the merit genetics of the superior boars and increasing the economic benefits in pig reproduction and breeding.

Feed Conversion Rate

The performance of Nile tilapia (Oreochromis niloticus) raised in cages furnished with an automatic dispenser, supplied at different frequencies (once per hour and once every two hours) and periods (daytime, nighttime and both) was evaluated. Eighteen 1.0m³ cages were placed into a 2000m² pond, two meters deep with a 5% water exchange. One hundred and seventy tilapias, with initial weight of 16.0±4.9g, were dispersed into each 1m³ cage and the feed ration was adjusted every 21 days with biometry. Data was collected from March to July (autumn and winter). Significant difference to final weight (P<0.05) among treatments was observed. The increase in feeding frequency improves the productive performance of Nile tilapias in cages and permitted better management of the food. The better feed conversion rate for high feeding frequency (24 times day-1) can result in saving up to 360kg of food for each ton of fish produced, increasing the economic sustenance for tilapia culture and suggesting less environmental pollution.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

An experiment was carried out to find the salinity tolerance capability and growth performance of Climbing Perch, Anabas testudineus (Bloch, 1795). Anabas testudineus commonly cultured fish in Bangladesh was reared in laboratory conditions at different salinities of 0, 3, 6, 9, 12, 15, 18 and 21‰ for 60 days. Hundred per cent survivals were detected at 0, 3, 6 and 9‰ salinity while 100% mortality was recorded at 18 and 21‰ salinity. Various responses to threat and feeding were observed among the fish in different treatments. Lowest feed conversion ratio was found in the control group while the highest was detected at 15‰ salinity. On the other hand, decreasing trend of specific growth and average growth rate were observed in A. testudineus fingerlings from 0 to 15‰ salinity. Significantly higher specific growth rate and average growth rate were detected in A. testudineus fingerlings reared at 0 - 6‰ salinity (p < 0.05). The present study suggests that Climbing Perch fingerlings can be reared at fresh water growth rates in coastal water with salinity up to 6‰.Dhaka Univ. J. Biol. Sci. 25(1): 65-73, 2016

Background: Fat and oil are commonly used in poultry diets to increase energy density and also to increase the palatability of feed, feed efficiency and for deposition of fat in broilers. Thus a study was proposed to find the effects of dietary replacement of saturated fatty acid rich palm oil (PO) by omega-3 rich rapeseed oil (RO) on growth performance and economics in broilers. Method: The growth performance feeding trial was conducted in 160 day-old broilers (vencobb 400) with four treatment groups (G1, G2, G3 and G4) with four replicates of ten chicks each. The basal diet (R1) was prepared with palm oil included at the rate of 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher ration, respectively and fed to G1. The other treatment groups G2, G3 and G4 received R2, R3 and R4 experimental rations respectively. The experimental rations R2, R3 and R4 were prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil which was included in R1. Result: The broiler ration prepared with rapeseed oil at 50 and 100 per cent level (G3 and G4) replacing palm oil showed increased body weight gain (P less than 0.01) and better feed conversion ratio (P less than 0.05) than G1 group. There was no significant difference in the feed intake among the different treatment groups. Profit per kg live weight in G3 (Rs.12.06) and G4 (Rs.11.14) was more than G1 (Rs.8.21) and G2 (Rs.6.57). The supplementation of omega-3 rich rapeseed oil had significantly improved the performance of broilers.
