Background: Probiotic is the best solution (Produce antimicrobial compounds, inhibit colonization of pathogenic microorganism, increase digestive ability and confer better health to the host) as an alternative to antibiotics against various microbial infection in freshwater and marine water. The freshwater fish Cyprinus carpio was selected for this research work (due to high growth rate, high protein content, ability to survive under different climatic conditions and its availability throughout the year) to observe the effect of probiotic Enterococcus gallinarum N3 supplemented feed on its growth. Methods: In this present research work Prepared three different concentration of probiotic Enterococcus gallinarum N3 (0.1%. 0.5% and 1.0%) along with basal diet containing other ingredients (fish meal, groundnut oil cake, wheat bran, starch and Vitamin mineral premix). Initially 14 days acclimatized freshwater fish Cyprinus carpio to laboratory condition selected randomly for four treatment groups as Control (C) and probiotic feed treated T1, T2 and T3 group. The experiment was carried out for 42 days with continuous aeration, natural photoperiod of 16 hrs light and 8 hrs dark, maintain temperature constant and fishes fed diet twice daily. The feed ingredients and experimental diets analysed for proximate composition and measured Weight gain, Specific growth rate (SGR), and Feed conversion efficiency (FCE). Result: The proximate composition of the feed was determined as percentage dry matter in which 36.21% protein, 6.8% moisture and 7.8% of lipid. The probiotic feed experiment was conducted for 42 days and entire group of fishes was survived. The effect of probiotic feed on growth performance of Cyprinus carpio was measured as initial weight, final weight, weight gain, specific growth rate and feed conversion efficiency. The growth changes were observed before and after treatment with 0.1%, 0.5% and 1.0% of probiotic E. gallinarum N3 fed to Cyprinus carpio. The final weight (g) and final length (cm) was measured in treatment T1 (3.107 g; 3.32 cm), T2 (3.258 g; 3.40 cm) and T3 (3.413 g; 3.52 cm) respectively as compared with Control group C (2.255 g; 2.98 cm). The percentage weight gain obtained in group T1 (37.78%), T2 (44.45%) and (51.55%) respectively as compared with Control group C (29.54%). Maximum specific growth rate was observed in treatments T1 (0.94 % day-1), T2 (0.99% day-1) and T3 (1.02% day-1) as compared with control group C (0.56% day-1). The results showed better growth performance and feed utilization in all the three treated groups T1, T2 and T3. The best growth performance (final weight, final length, weight gain, specific growth rate and feed conversion efficiency) and feed utilization (moisture, protein and lipid) was observed best in T3 (1 g kg-1) group of fishes as compared to control C group. There was significant difference (P greater than 0.05) in final weight, final length, weight gain, specific growth rate and feed conversion efficiency.

Thai pangus polyculture with carps has been increasing for its high potential, however very few attempts were made to compare its growth using different types of feed. A research was undertaken to assess the effect of three types of feed on growth of Thai pangus (Pangasius hypophthalmus) and rohu (Labeo rohita) in polyculture system for 11 months from 15 May 2005 to 15 April 2006 in Khulna. Growth performance using Hand-made Feed (F1) was compared with two commercial fish feed, Sunney Feed (F2) and Saudi-Bangla Feed (F3) in three respective treatments of T1, T2 and T3. All treatments were carried out in triplicate at 24700/ha for Thai pangus and 4940/ha for rohu. Average initial weight of Thai pangus and rohu were 4.5 and 33.5g respectively. Growth performance was influenced by feed type. Average final weight of Thai pangus and rohu were 820 and 710; 846 and 770; and 872 and 717g with specific growth rate 1.58 and 0.93; 1.59 and 0.95 and 1.60 and 0.93 % day -1 in T1, T2 and T3 respectively. Feed conversion ratio was estimated 2.3 in T1, 2.1 in T2 and 1.96 in T3. The result showed a typical increasing trend of final weight and specific growth rate of Thai pangus along with the increasing of feed protein level. But rohu showed highest growth in T2 where protein level was 26-30% which was lower than that of T3 (Protein level 28-32%). The study suggests that suitable protein level and quality feed is required for adequate growth of fish.

The present study aimed to investigate the effect of fish grading on the growth performance of common carp Cyprinus carpio cultivated in floating cages located in the Al-Mashab River northwest of Basrah. A total of 4896 fishes were transferred from storage cages to culture cages (3×4×2 m), and distributed at a rate of 816 fishes per cage with a culture density of 34 fishes/m3 into six cages, three of which were classified into large (GL), middle (GM) and small (GS) individuals, whereas three cages were left without grading (UG). The graded and ungraded cages were chosen depending on the standard deviation for each cage. The fishes were fed for both treatments on a standardized, locally made diet. The results of the study were evaluated according to the criteria for total weight gain (WG), daily growth rate and specific growth rate. In the first grading process, significant differences (P<0.05) were recorded between graded (GL) and ungraded in final weight and specific growth rate (SGR) but not in weight gain and daily growth rate (DGR), while in the second grading, significant differences (P<0.05) were recorded between graded (GL) and ungraded in final weight and weight gain but not in SGR and DGR. At the end of the second grading period, the daily and specific growth rate of graded fishes were ranged between 3.26-4.73 g/day and 0.22-0.46%/day, respectively, while for ungraded fishes there were 2.35 g/day and 0.23%/day, respectively. The survival rate (SR) was not different very much in all treatments and ranged between 94.34 to 95.49% in small graded and ungraded fishes, respectively. The study results recommend at least two grading processes should be established during the culture season in two or three months intervals.

The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.

Fat Snook

We aimed at evaluating the effects of different water temperatures on the zootechnical performance of fat snook. The experiment lasted for 60 days, which was conducted in water recirculation systems, and was randomly designed with three treatments and three replicates each, corresponding to three water temperatures (25, 28 and 31°C). A total of 225 fat snook juveniles with a mean weight of 6.45 ± 0.58 g were used, which were fed daily until apparent satiety. Zootechnical parameters were assessed and feeding rates were registered for each tested temperature. Survival rates varied from 96 to 100% among treatments. Higher values of standard and total length, and weight gain were found in 28 and 31°C (p < 0.05). With regard to final weight, final biomass, feed conversion and specific growth rate, no significant differences were observed (p > 0.05). Feeding rates did not differ among evaluated temperatures. The results show that the used temperatures did not negatively affect zootechnical performance of fat snook juveniles.

Feeding Diets

Two experiments were conducted, using a total of 288 crossbred boars, gilts and barrows from the progeny of two Yorkshire sow lines, one kept as control, and the other selected for lower backfat thickness and increased growth rate for six generations. The lysine to DE (g MJ−1) levels used during grower (20 to 60 kg) and finisher (60 to 105 kg) periods, respectively, in the three diets (14.2 MJ DE kg−1) were: 1) 0.53 and 0.42 with no other supplemental amino acids except lysine, 2) 0.69 and 0.57 with supplemental threonine and methionine at a ratio of 0.65 and 0.30 to dietary lysine and 3) 0.85 and 0.72 with supplemental threonine and methionine at similar ratios as in diet 2. Feeding diets 2 and 3 increased (P < 0.05) the ADG and feed conversion efficiency of all pigs in both experiments, and this response was mainly during the grower period. Feeding diet 3 improved the growth rate more than diet 2 only in boars and gilts but not barrows. It also increased the feed conversion efficiency in exp. 2. The increased feed conversion efficiency response was higher in select than control line pigs, and in boars. Feeding diets 2 and 3 also improved the carcass merit but reduced the meat quality with an increased firmness and reduced marbling, juiciness, and flavour. The overall results indicated that an average daily intake of approximately 17 g of lysine (0.74 g MJ−1 DE), 11 g of threonine and 5 g of methionine during the grower period and 25 g lysine (0.62 g MJ−1 DE), 18 g threonine and 8 g methionine during finisher period optimized the growth performance, lean growth rate and carcass merit. This response tended to be higher in select than control line, and in boars and gilts than barrows. Key words: Lysine, amino acids, energy, growth, carcass, pigs

An experiment was designed and carried out to assess the growth performance and feed utilization (weight gain, feed conversion ratio, protein efficiency ratio, specific growth rate, feed intake and survival) of Clarias gariepinus fingerlings fed graded levels of toasted Leucaena leucocephala seed meal based diets with the aim of establishing the best inclusion level of Leucaena seed meal. One hundred and eight (108) fingerlings with an initial mean weight of 2.10g were allotted at random to six treatments in triplicate groups with each treatment tank having six fingerlings and were fed with isocaloric and isonitrogenous diets containing 40% crude protein (CP). The toasted seed meal was used to replace soybean meal in the diets in the following proportions: diets I (0%), diets II (10%), diets III (20%), diets IV (30%), diets V (40%) and diets VI (50%). At the end of the feeding trials that lasted for 6 weeks, the mean weight gains of fish, relative weight gain, specific growth rate, feed intake, feed conversion ratio and protein efficiency was highest in treatment I while mean weight gain of fish, relative weight gain, specific growth rate and feed conversion ratio was lowest in treatment V. Feed intake was lowest in treatment VI and protein efficiency was lowest in treatment II. Survival among treatments slightly varied significantly but was not as a result of the feed consumed. At the end of the experiment, the recommended inclusion level of Leucaena seed meal was 20%.

Abstract Lobster is among freshwater crustaceans which is potentially cultivated in aquaculture system. This present study was conducted to determine the growth and survival rate of freshwater lobster Cherax quadricarinatus fed different forage feed. The experimental methode used a completely randomized design consisted of 4 treatments in triplicate: commercial diet (PL), commercial diet and carrots (PW), commercial diet and potatoes (PK) and commercial diet and sweet potatoes (PU). The experimental lobsters were 5-7 cm in size and 6-8 g in weight. Results indicated that forage feeding can affect the total weight and length, weight gain, specific growth rate and survival rate of lobster. Data showed the best weight gain and specific growth rate were found in PW (34.37±0.30%) and (1.05±0.03%), respectively. The lowest survival rate was seen in PU at 86.67%. However, the best feed conversion ratio gained by PL at 1.74±0.09. This study suggested that the combination of commercial diet with carrots provided the best growth performances in freshwater lobster Cherax quadricarinatus.

Weight gain, shoulder height and feed intake responses to immunization against somatostatin (SRIF) were examined in three experiments with a total of 78 lambs. Initial immunizations against SRIF occurred when lambs were 4, 8 and 3 wk old for exps. 1, 2 and 3, respectively, with booster immunizations 2, 4, 6, 8 and 10 wk later. Control lambs were left untreated except in exp. 3 where one group of control lambs was immunized with human serum alpha globulin. Treated lambs were immunized with SRIF conjugated to human serum alpha globulin. Experiments were terminated when lambs reached 45 kg body weight. SRIF immunization did not alter lamb shoulder height or feed conversion efficiency. Rate of gain of ram and wether lambs, but not ewe lambs, was improved by SRIF immunization. Wether lambs in exp. 1 and ram lambs in exp. 2 gained 21 and 15% more, respectively, than their controls by 20 wk of age. In exp. 3, SRIF-treated 3/4 Romanov ram lambs gained 13% more than their controls by 19 wk of age. However, SRIF-treated 7/8 Romanov lambs gained only 3% more than controls during this time. In conclusion, immunizing wether and ram crossbred lambs against somatostatin increased their growth rates sufficiently to reduce the time needed to reach market weight by 2–3 wk. However, feed conversion efficiency was not improved by somatostatin immunization. Key words: Somatostatin, SRIF, immunization, growth rate, lambs
