European catfish (Silurus glanis L.) is a fish that has a high economic value due to its rapid growth and delicious flesh. In this study, the growth performance of European catfish was investigated in freshwater and 5‰ salinity in recirculating system. The study was carried out using fish with an average weight of 507±13.02 g and an average total length of 42.85±0.45 cm in freshwater (Y1, Y2, Y3) and 5‰ salinity of ground water (T1, T2, T3) designed as three replications for three months. Fish were fed with 3% of the total weight two meals a day. The mean body weight gain, total lenght increase, amount and percentage of feed consumption, specific growth rate (SGR) and feed conversion rate (FCR) were higher in group Y (P<0.05). No statistical difference was observed between the survival rates of the groups (P>0.05). As a result, it is concluded that this species can be reared in both fresh water and 5‰ saline water.

AbstractA total of 211 pheasants (Phasianus colchicus) were reared using two different production systems (free range and intensive) to determine the effect of production system and slaughter age on growth performance and carcass traits. Birds were slaughtered at 14, 16, and 18 weeks of age. Production system did not significantly affect body weight until 18 weeks; at this age, pheasants reared in free range exhibited a higher average weight (1149 g vs. 1012 g). Total feed consumption and feed conversion ratios did not differ among production systems. The most in-demand portions of the carcass (breast and leg) were not affected by differences in production system. The leg and breast proportions which were the most edible parts of the carcass were around 26% and 35%, respectively, in both free-range and intensive systems.

Abstract The purpose of this study was to evaluate the growth performance of Peking ducks fed with rations containing waste products of leubiem fish (Chanthidermis maculatus) and probiotic agents. The study was conducted experimentally using 96 Peking ducks, within an age range of about 1 to 8 weeks, and a Completely Randomized Design (CRD), which consisted of four treatment rations and four replications. The treatment rations used in this research included treatment R0, which was the basal diet, serving as the control ration, and also treatment R1, R2, and R3, which consisted of 10% concentration of leubiem fish skin, head, and bone, respectively, as well as 1% of a probiotic agent. The observed variables included the rate of feed consumption, body weight gain, final body weight, feed conversion ratio, and mortality were then analysed using Analysis of Variance (ANOVA). The results showed that the use of leubiem fish components and probiotic agents in rations at 10% and 1%, respectively, had a significant effect (p<0.05) on the rate of feed consumption, body weight gain, feed conversion ratio and final body weight. However, there was no significant effect on the mortality of Peking ducks. Therefore, this study concluded that the use of rations containing leubiem fishbone and probiotic agents at 10% and 1%, respectively, were able to accelerate the growth performance of Peking ducks.

A study was conducted for 56 days to observe the effect of varied levels of dietary crude protein and metabolizable energy on growth performance in 720 day-old Giriraja chicks, which were divided equally into nine groups of 80 birds each. Nine different experimental diets were formulated with three levels 2700, 2800, and 2900 kcal of metabolizable energy (ME/kg), each with three levels of protein (CP), viz., 19%, 20%, and 21%, respectively and Group T5 served as control fed with 20% protein and 2800 kcal energy as per BIS (2007) requirements. Feed consumption, body weight gain, and feed conversion ratio (FCR) were analysed up to 56 days. The results of the study indicated that diet containing 20% CP with 2900 kcal ME/kg showed enhanced growth performance in Giriraja chicks.

Fisheries Resources

One of the main problems facing aquaculture is the lack and high price of fishmeal and fish oil supply. The continued growth of aquaculture production cannot depend on these finite fisheries resources. It is imperative that inexpensive and readily available alternatives that do not compromise fish growth and product quality are found. It is in this specific context that this study consisting of a test of the Balanites aegyptiaca seed oil incorporated in the feed of Clarias anguillaris fries was conducted.The experiment lasted eight (8) weeks and included five treatments of two tanks each. This corresponds to a total of 10 tanks for 150 fries with a stocking density of 15 fish per tank. Five diets supplemented with 0% (R.0), 1% (R.1), 2% (R.2), 3% (R.3) and 4% (R.4) of the lipid source were administered twice daily for eight weeks. Growth was regularly monitored and mortalities recorded to assess the effects of each diet. The results revealed significant effects on growth performance and survival of Clarias anguillaris fries. For the average weight gain and the specific growth rate, the best result was obtained with the fish fed with diet containing 2% Balanites aegyptiaca seed oil (R.2). The best feed conversion ratio was recorded with the diet incorporating 2% of this oil. The best survival rates (66.67% and 70%) were observed in fries fed with diets incorporating respectively 2% and 3% of the oil. The experimental study has shown that a 2% incorporation rate is the most appropriate for the successful rearing of Clarias anguillaris fries.

Abstract. The present study investigated the growth performance, weight gain, feed conversion ratio, growth and survival rate of European catfish (Silurus glanis L.) fingerlings reared for one month in tanks with different colours. Four colours were used: light blue, white, green and black. The experimental unit was a flow-through system (0.8 L.min-1) consisting of eight tanks with water volume of 30L, continuous air supply and water heaters. Two hundred fish with an average weight of 1.85±0.62g were stocked in each tank. Results from the study demonstrated that the weight gain and the feed conversion ratio were poorly affected by the tested tank colours. Weight gain is slightly higher in groups A (blue) and B (white) than in groups C (green) and D (black). However, no significant difference was found in terms of weight gain among the experimental groups (p>0.05). Survival rate was the highest in group C (91%) followed by group D (88.5%). Thus, for rearing of European catfish fingerlings it is preferable to use dark coloured tanks, which resemble the natural habitat of the fish.

Giant gourami has a high economic value, but slow growth. To overcome this problem, it is necessary to improve the quality of feed and the cultivation system. Feed used in this experiment was formulated feed with different ratio of combination of fish meal and azolla fermented flour. The cultivation system used in this study was a recirculation system. This study aimed to determine the effect of different ratio of matterials combination in feed on the growth performance of gouramy. This study used an experimental method with the completely randomized design with 5 treatments and 3 replicate. The treatments were the ratio of combination between fish meal and azolla fermented flour, viz: A (100:0%), B (75:25%), C (50:50%), D (25:75%) and E (0:100%). The body size of fish ranged of 7 – 9 cm with an average weight of 8.8 g ind.-1. The results showed that the provision of artificial feed with different combinations gave a significant effect (P<0.05) on growth performance of gourami. The best results were obtained in treatment B with the value of specific growth rate of 0.52±0.01, absolute body weight of 2.06±0.05, feed consumption rate of 93.63±0.43, protein efficiency ratio of 6.39±0.16 and the feed convertion ratio was 1.00±0.25. The best protein retention was achieved in treatment B with the value 13%.

Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) results in impaired bird growth performance and increased production costs. Nanotechnology application in the poultry industry to control NE outbreaks is still not completely clarified. Therefore, the efficacy of dietary garlic nano-hydrogel (G-NHG) on broilers growth performance, intestinal integrity, economic returns and its potency to alleviate C. perfringens levels using NE challenge model were addressed. A total of 1200 male broiler chicks (Ross 308) were assigned into six groups; four supplemented with 100, 200, 300 or 400 mg of G-NHG/kg diet and co-challenged with C. perfringens at 21, 22 and 23 d of age and two control groups fed basal diet with or without C. perfringens challenge. Over the total growing period, the 400 mg/kg G-NHG group had the most improved body weight gain and feed conversion efficiency regardless of challenge. Parallel with these results, the mRNA expression of genes encoding digestive enzymes (alpha 2A amylase (AMY2A), pancreatic lipase (PNLIP) and cholecystokinin (CCK)) and intestinal barriers (junctional adhesion molecule-2 (JAM-2), occludin and mucin-2 (Muc-2)) were increased in groups fed G-NHG at higher levels to be nearly similar to those in the unchallenged group. At 14 d post challenge, real-time PCR results revealed that inclusion of G-NHG led to a dose-dependently decrease in the C. perfringens population, thereby decreasing the birds’ intestinal lesion score and mortality rates. Using 400 mg/kg of G-NHG remarkably ameliorated the adverse effects of NE caused by C. perfringens challenge, which contributed to better growth performance of challenged birds with rational economic benefits.

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

Dietary Treatments

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.
