Oreochromis niloticus be-coming a promising aqua-culture species globally, but recent disease outbreaks and poor growth with commer-cial feed making it chal-lenging. A 60 days long aquarium trial and series of laboratory assays have been conducted to assess the growth performance of O. niloticus fed with a locally available commercial pro-biotic. O. niloticus fry’s were fed with a mixture of basal diet and probiotics supplementation at a level of 0% (control), 0.2%, 0.4% and 0.8%. After the trial phase weight gain, length gain, specific growth rate (SGR), percentage of weight gain (PWG), percentage of length gain (PLG) were not-ed. Among all, highest val-ues of above parameters were observed at T1 (0.2%) treatment group. Weight gain, length gain, PLG and PWG were significantly im-proved in T1 treatment group (p<0.05). Additional-ly, hematological parame-ters including hemoglobin (Hb), white blood cell (WBC) and red blood cell (RBC) were also observed for all groups and T1 was found to have highest values for all these parameters, alt-hough there were no statis-tically significant differ-ences between the values of T1 and T2. The results of this study showed that 0.2% dietary probiotics supple-ments in basal diet would optimize the growth per-formance and hematological parameters of aquarium reared O. niloticus.

Two 8-week feeding trials were conducted to determine the dietary Na requirement for juvenile hybrid tilapia (Oreochromis niloticus × O. aureus) reared in fresh water and seawater. In each experiment, NaCl was added to the basal diet at 0, 0·5, 1, 2, 3, 5, or 7g Na/kg diet (fresh water) and at 0, 0·2, 0·5, 0·8, 1·2, 1·5, 2, or 3g Na/kg diet (seawater). Each diet was fed to three replicate groups of fish, individual fish initially weighing 0·69 (se 0·01) g, in a closed, recirculating rearing system. In fresh water, the tilapia fed the diet supplemented with 2g Na/kg diet had significantly (P<0·05) greater weight gain than the fish fed the diets supplemented with ≥3 and ≤0·5g Na/kg diet. Feed efficiency (FE) in fish generally followed the weight-gain pattern. Gill Na+–K+ ATPase activity was highest in the fish fed the diets supplemented with 1–3g Na/kg diet, followed by the fish fed the diet with 7g Na/kg diet and lowest in the fish fed the unsupplemented control diet. In seawater, the weight gain, FE and gill Na+–K+ ATPase activity in fish were not affected by the dietary treatment. Analysis by polynomial regression of weight gain, by broken-line regression of gill Na+–K+ ATPase activity and by linear regression of whole-body Na retention of the fish reared in fresh water, indicated that the adequate dietary Na concentration for tilapia is about 1·5g/kg diet. The present study also suggests that no dietary Na is required for tilapia reared in seawater.

Abstract Background The aim of this study is to investigate whether the energy matrix values of the nonstarch polysaccharide- (NSP-) degrading enzymes, bioemulsifier (LYSOFORTE®), guanidinoacetic acid (CreAMINO®), or their combinations could be summed. The effects of these additives on the growth performance, carcass traits, and economic value of the broiler chicken diets were evaluated. A total of 525-one-day-old Ross chicks with an initial body weight of 42.96 ± 0.87 g were haphazardly allocated into seven groups with five replicates. The seven experimental treatments are as follows: (1) basal diet with no additives (breeder recommendation), which is the control group, (2) basal diet minus 100 kcal/kg supplemented with 0.02% NSP-degrading enzymes (NSP), (3) basal diet minus 50 kcal/kg supplemented with 0.025% emulsifier (LYSOFORTE®), (4) basal diet minus 50 kcal/kg supplemented with 0.06% guanidinoacetic acid (CreAMINO®), (5) basal diet minus 150 kcal/kg supplemented with a mixture of NSP and LYSOFORTE® (NSPL), (6) basal diet minus 100 kcal/kg supplemented with a mixture of NSP and CreAMINO® (NSPC), and (7) basal diet minus 200 kcal/kg supplemented with a mixture of NSP, LYSO, and CreAMINO® (NSPLC). The experiment lasted for 35 days. Results It was found that the final body weight, body weight gain, and relative growth rate were significantly higher in birds fed diets supplemented with NSPL, NSPC, CreAMINO, and LYSO with the reduced energy matrix value. The overall feed conversion ratio was significantly improved due to the supplementation of NSPC, CreAMINO, NSPL, and LYSO with the reduced energy matrix value compared to the control group. Moreover, no significant effect on the carcass criteria was observed by the different treatments. As a result of the dietary supplementation with NSPL, NSPC, CreAMINO®, and LYSO with the reduced energy matrix value, the net profit, total return, economic efficiency, and performance index were increased and the cost of feed per kg of body weight gain was decreased. Conclusion The energy matrix value of NSPL, NSPC, CreAMINO®, and LYSOFORTE could be established in the diets of broiler chickens to improve the growth performance and economic efficiency.

Mercury toxicity in tilapia, Oreochromis niloticus, (Linnaeus, 1758) was investigated by the hematological parameters after long-term (14 days) exposure to various Hg concentrations (0.02, 0.002, 0.0002mg/L Hg). Test groups were set up with three replicates for each concentration, plus the control group. Blood samples were collected from six individuals for each concentration at 0, 3, 7, 10 and 14 days of exposure. The hematological parameters analyzed were: total red blood cell count (RBC), hemoglobin concentration (Hb), hematocrit (Ht), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), total white blood cell count (WBC) and differential leukocyte counts and total thrombocyte count (Tr). There were no significant differences among the mean hematological values at the different Hg concentrations indicating that Hg at the concentrations studied was not toxic to tilapia.

Incorporating feed additives in diets of cultured fish is aimed at improving growth performance, immunity and carcass quality. Growth performance and some haematological parameters of Oreochromis niloticus fingerlings fed varying inclusion levels of Corchorus olitorius seeds were assessed in the study. O. niloticus fingerlings of initial mean weight 9.35±0.01g were evaluated for a period of 56 days. Five experimental diets were formulated at varying inclusion levels; 0g/100g (control), 0.5g/100g, 1.0g/100g, 1.5g/100g and 2.0g/100g of C. olitoriusseeds. All diets were isonitrogenous with each treatment having triplicates. O. niloticus fingerlings fed 1.5g/100g diet of C. olitoriusrecorded the best growth performance in terms of weight gain, feed conversion ratio (FCR) and specific growth rate (SGR). There was a significant increase in growth and nutritional performance of O. niloticus fingerlings with increasing inclusion of C. olitorius seeds (P<0.05). Significant increase in packed cell volume, white blood cell and haemoglobin were observed in treated O. niloticus fingerlings and there was no adverse effect of C. olitorius seeds on the haematological parameters of the fish. The study showed that C. olitorius seed at 1.5g/100g significantly improved survival rate, weight gain and feed conversion ratio as well as reduced mortalities in the treated groups.

Three commercial premix types were fed in and duplicated to six groups of 45 broilers each at the starter pbase (0-5 weeks). At the finisher phase (5-9 weeks) each treatment group of the vital roles in starter was further divided into three groups. Nine premix combinations were used at the finisher pbase. Performance of the birds was monitored. At the starter phase, birds fed premix Z diet had a mean body weight blood (629.90gm) that was higher (P<0.05) than fed premix A diet (518.87 gm) which was also the maintenance of osmotic relations and acid higher than those fed premix U diet (414.59gm). The mean daily weight gain followed the same  trend with 16.81gm, 14.04gm, or 10.58 gm for birds fed diets that contained premixes Z A or U respectively. Birds fed a diet that contained premix Z consumed 48.80 gm daily which was  more than those for birds fed premix U in their diet (37.85gm). The feed to gain ratio was not significantly affected (P>0.05) by the premix  type fed at this phase. Poor growth rate caused by premixes with marked differences in their by premix fed at the starter phase was not completely overcome due to the premix type fed at the finisher phase varied (P<0.05) with the type of premix fed. No difference (P>0.05) was observed among the  premix types for the metabolic trials at the starter phase.

ABSTRACT: The purpose of this study was to assess the levels of available phosphorus (AP) in the diet of growing pigs selected for lean deposition on the hematological, biochemical, and bone performance parameters. A total of 64 commercial hybrid pigs (32 castrated males and 32 females; mean initial weight: 23.31±2.4kg; age: 55-90 days) were used. Animals were distributed into a randomized block design with four treatments, eight replicates, and two animals (one male and one female) per experimental unit. The treatments consisted of a basal diet and another three diets, which were obtained by supplementing the basal diet with dicalcium phosphate replacing the inert phosphate, resulting in four diets with 0.100, 0.180, 0.260, and 0.340% of available phosphorus. The levels of available phosphorus quadratically influenced the daily weight gain, feed consumption, and feed conversion, which increased up to the estimated levels 0.331; 0.330, and 0.302% of available phosphorus. Levels of phosphorus showed no influence on the hematological parameters, which remained within the reference values. Levels of available phosphorus increased linearly the ash and phosphorus contents in the metacarpal bone and decreased linearly the alkaline phosphatase activity. Levels of available phosphorus (0.331 and 0.302%, corresponding to a daily intake of 5.73 and 5.18g d-1) provided respectively the best results for weight gain and feed conversion in pigs with high genetic potential, without change in hematological parameters.

Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC’s 7.97 ×103mm-3, RBC’s 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

A factorial trial was conducted to detect the effect of different feeding strategies of supplementation of effective microorganisms (EM) liquid on the growth performance, feed utilization, body chemical composition and economic efficiency of monosex Nile tilapia (Oreochromis niloticus) juveniles. Three experimental treatments were formulated a basal diet without any addition of EM (control; A), a diet supplemented with 2% EM (B), and a diet supplemented with 4% EM (C). All treatments were offered to fish through two different strategies of feeding the meal: 2/3 in the morning and 1/3 in the afternoon or 1/3 in the morning and 2/3 in the afternoon. Each treatment was replicated three times. Juveniles Nile tilapia with an average initial body weight of 3.85 ± 0.22 g (± SE) were randomly stocked at a rate of 90 juveniles per 1.5 m3 tank. Fish growth performance and feed utilization significantly (P ≤ 0.05) increased with increasing EM supplementation and were positively affected by different feeding strategies. Moreover, the economic evaluation showed that there were more benefits by when using the 4% EM diet and feeding 2/3 of daily meal in the morning.
