The experiment was conducted to evaluate the requirement of cyanocobalamin of male Pekin ducks from hatch to 21 days of age. A total of three-hundred-eighty-four, one-day-old meat-type male Pekin ducks were randomly allocated to six treatments, i.e., dietary cyanocobalamin (vitamin B12) concentrations of 0.00, 0.02, 0.04, 0.06, 0.08 and 1.00 mg/kg, respectively in their feed. Each treatment had eight replicated pens with eight ducks for each pen. Feed and water were provided ad libitum. The experiment was conducted for 21 days. Different growth parameters including average daily weight gain (ADG), average daily feed intake (ADFI), feed conversion ratio (FCR), and hematological indicators were evaluated because, on the basis of hematological indicators, the health and nutritional status of an animal can be accessed. It is observed that supplemental cyanocobalamin has no significant effect on ADG, ADFI, and FCR but it improves hematological parameters such as white blood cells, red blood cells, and its indices and platelet counts compared to the control group (p < 0.05). On the basis of growth performance and hematological indicators it is concluded that 0.02 mg cyanocobalamin/kg of feed is the dietary requirement of male Pekin ducks from hatch to day 21 of age.

In this study, the influence of new multi-strain synbiotics on chicken growth performance, hematology, serum biochemistry and immunity was explored. Each synbiotic preparation (A, B and C) comprised three, four or five strains of Lactobacillus sp., respectively, as well as S. cerevisiae and inulin. All strains used in the synbiotics originated from wild-type strains from animal farms in Poland. Six groups of chickens, ROSS 308 line, were fed with three different synbiotics at a dose of 0.5 g/1 kg of feed. Body weight, as well as the biochemical and hematological parameters of the animals in each study group, were determined on the 7th, 14th, 28th and 42nd day of life. Body weight on day 42 differed between groups and was the highest in control group. This group also had the highestfeed conversion ratio (FCR) value. All measured biochemical parameters were in the normal ranges for poultry; however, we observed a lower alkaline phosphatase (AP) concentration on day 7 in the groups fed with synbiotics, which correlated with a lower level of triglycerides in those groups. The aspartate transaminase (AST) concentration was significantly lower in all groups on day 42 in comparison with the control. On day 7, the control group showed the highest concentration of Ca, K and P. Other parameters did not differ significantly throughout the experiment. All groups showed a similar tendency of increase in the red blood cells (RBC) count according to the age of the birds. Every white blood cells (WBC) population showed differences in the proportions between T and B lymphocytes. The T cell and monocyte counts increased until day 28 in all groups. The results showed that our newly developed synbiotic formulas do not have any unfavorable influence on chicken health and may modulate immune response and biochemical parameters. However, this hypothesis needs to be evaluated in future experiments.

The aim of the present study was to assess effects of selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. The study was performed on 240 1-day old ducklings of the same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with the following four different levels of Se yeast (ALKOSEL® R397): groups with Se at 0 mg/kg of the diet as-fed, 0.2 mg/kg, 0.4 mg/kg and 0.6 mg/kg. Growth performance (bodyweight, daily weight gain, daily feed intake, feed-conversion ratio) and carcass characteristics (hot and cold carcass weight, chilling losses, dressing percentage, carcass cut yields, and percentage of tissues in breast and thighs with drumsticks) of the ducks were determined. Animals fed high-Se diets (0.4 mg/kg) had higher (P &lt; 0.05) final bodyweight and daily weight gain (from 15 to 49 days) compared with those fed diets with inadequate (0 mg/kg) or with supranutritional (0.6 mg/kg) Se levels. Ducks fed only with basal diet showed a higher (P &lt; 0.05) feed-conversion ratio (from 15 to 49 days) compared with those supplemented with Se at 0.4 mg/kg and 0.6 mg/kg. Dressing percentage was higher (P &lt; 0.01) in the control group (69.50%) than in the group with Se added at 0.6 mg/kg (66.85%). The weights of basic cuts from the duck carcasses did not significantly differ among compared groups. Moreover, the percentage of skin with subcutaneous fat in breast and thighs with drumsticks increased in Se-supplemented groups compared with the control group, while the opposite was determined with the percentage of muscle. It was concluded that a diet containing 0.4 mg of added Se per kilogram produced the greatest growth-performance results in ducks.

AbstractThis study evaluated the effects of grape seed extract (GSE) on the growth performance, immune response, and disease resistance of common carp (Cyprinus carpio). Fish were distributed in four groups and fed diets with varying levels of GSE at 0, 10, 20, and 30 g/kg for 56 days. The final length in fish fed with 20 and 30 g GSE/kg diet significantly increased in comparison with the control group (P<0.05). The final weight and weight gain of fish fed with GSE were statistically higher than the control diet, while the feed conversion ratio was lower in GSE groups than the control. Hematological parameters did not statistically enhance with GSE supplemented diets (P>0.05). However, fish fed with 30 g GSE/kg diet displayed a higher WBC count significantly than the other group (P<0.05). The serum total protein and globulin in fish fed with 20 g GSE/kg diet significantly increased compared to the control (P<0.05). A similar pattern was noticed in results for serum and mucus lysozyme activity with a significant increase in fish fed with 20 and 30 g GSE/kg diet compared to the control (P<0.05). Total antibody levels in serum and mucus samples were also increased in fish by dietary GSE with maximum levels by 20 and 30 g GSE/kg diet. Besides, mucus protease activity was higher in fish received 20 and 30 g GSE/kg diet with maximum level shown in fish fed with 30 g GSE/kg diet compared to the control group (P<0.05). Meanwhile, all groups showed higher mucus antibacterial activity against Aeromonas hydrophila with the highest activity in 30 g GSE/kg diet in comparison with the control group. The cumulative mortality was 36.67% when fish fed with 30 g GSE/kg diet and challenged with A. hydrophila. However, the mortality rate was 40% and 53.33% in fish fed 20 and 30 g GSE/kg diet, respectively. This study suggests that supplementation of GSE could significantly enhance the growth performance, immune responses, and disease resistance against A. hydrophila in common carp.

Wild cocoyam is a non edible plant found growing around riversides and can serve as source of energy to ruminants. Hence, a twelve weeks study was conducted to investigate the effect of wild cocoyam – urea meal on the growth performance and blood profile of West African dwarf (WAD) goats. Twelve WAD goats with an average weight of 7.25 ± 0.04kg were randomly allotted into four dietary treatments: T1 (raw wild cocoyam), T2 (urea treated wild cocoyam), T3 (urea treated cooked wild cocoyam) and T4 (urea treated fermented wild cocoyam), replicated thrice in a completely randomized design. Results obtained showed that the experimental diets significantly (p < 0.05) influenced the growth performance. Goats fed urea treated cooked wild cocoyam had the best feed conversion ratio (10.35), the highest values of dry matter intake (405.35 g/day) and daily weight gain (39.17 g/day) when compared to other dietary treatments. The dietary treatments did not significantly (p < 0.05) influence the haematological parameters except the red blood cells (9.62 - 11.67×106 mm3),white blood cells (4.07-9.05×106 mm3) and monocytes (1.00-2.50%). No significant (p>0.05) differences among the dietary treatments were observed in all the serum biochemical indices evaluated except for urea which ranged from 15.50 – 28.70mg/dl. It can therefore be concluded that addition of urea with processing, further improved the utilization of the experimental diets thus improving performance of the animals.

<p>The aim of this work was to study the effect of tropical green forage on rabbit growth performance and apparent digestibility. Thirty rabbits weaned at 35 d of age were individually caged and allotted to 2 dietary treatments. From 35 to 90 d of age, the control group C was fed <em>ad libitum</em> with commercial pelleted diet C only, while the test group was fed the C diet and forage <em>Pueraria phaseoloides</em> (Pp) <em>ad libitum</em>. Individual water and feed intake, body weight gain, nutrient apparent digestibility, red and white blood cells were studied. Mean housing temperature was 27.7°C. Water intake (35-90 d) did not differ between the 2 groups (mean=128 mL/d), whereas feed intake (35-90 d) was twice as high, with Pp (114 vs. 56 g; P=0.02). Forage intake doubled every 2 wk, averaging 50% of the total intake from 35 to 90 d of age. The growth rate was higher (+30%) in the Pp group after weaning (35-49 d) but did not differ between groups thereafter. The feed conversion was higher for the Pp group after weaning only (+ 87%; P&lt;0;05). Weight of rabbits and feed efficiency were not affected by forage addition. Organic matter digestibility of diet C alone was roughly twofold higher compared to C+Pp (P=0.03). Red blood cells were not affected by treatments (4.1×10<sup>12</sup> cells/L). However, the white blood cell count was higher in Pp than in C group (7.4×10<sup>9</sup> vs. 3.9×10<sup>9</sup> cells/L; P&lt;0.01). <em>P. phaseoloides</em> may be used as a complement to a balanced pelleted feed, but further studies with a large number of rabbits are necessary to analyse the potential impact on health status.</p>

Background: Anemia of chronic disease (ACD) occurs in the presence of chronic infection, inflammatory conditions or neoplastic conditions despite of adequate iron and vitamins storage. Gingivitis is the inflammation of the gingiva, periodontitis is the inflammation in the periodontium that extend deeper with loss of connective tissue attachment and supporting bone. The main pathogenesis of periodontal diseases and ACD is immune activation. Aims of study: Determine and compare the clinical periodontal parameters (plaque index (PLI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment level (CAL)). Evaluate the hematocrit (Hct) level, red blood cells (RBCs) count and white blood cells (WBCs) count. Assess the correlations between the clinical periodontal parameters and hematological parameters at patients had gingivitis, chronic periodontitis (CP) with different severities (mild, moderate and severe) with healthy periodontium subjects. Materials and Methods: 35-50 years old, 150 male subjects were included in this study. They were divided into three study groups: group of 30 patients with gingivitis, group of 90 patients with CP which subdivided into (Mild CP=30 patients, Moderate CP =30 patients, Severe CP =30 patients) and control group 30 subjects with clinically healthy periodontium. Blood samples were collected then by automated blood analyzer the Hct, RBCs and WBCs were evaluated. Results: Comparisons among groups and subgroups revealed significant differences in Hct and WBCs, while RBCs was non-significant. Means values of RBCs count showed reduction in mild and severe CP subgroups. while, the Hct and WBCs mean values increased in patients with periodontal disease. The correlations between the clinical periodontal parameters with WBCs and RBCs were almost non-significant but, with Hct was mostly significant negative correlations. Conclusion: Inflammatory and immune responses in periodontal diseases caused change in different hematologic parameters which could contribute to the development of anemia of chronic disease.

Effect Of Water

The use of water with a modified isotopic composition in the diet of humans and animals, for example, with a reduced deuterium content, affects the rate of biological processes. In this regard, the targeted formation of the isotopic D / H gradient in the body can be used to increase its adaptive properties to external influences. Primates have a high anatomical and physiological similarity with humans, therefore, are an indispensable model for reproducing various pathological and toxic conditions in humans. The aim of the study was to study the effect of water with a low deuterium content on the hematological and biochemical blood parameters of rhesus monkeys and on the digestibility of nutrients of the diet. In the control group, primates consumed water with a natural regional content of deuterium equal to 150 mg / l, and in the experimental group - with reduced to 50 mg/l. The duration of the experiment was 35 days. The material for the study was venous blood, serum and feces of primates. Blood was drawn from monkeys before the use of deuterium depleted water and after the completion of the experiment. All blood samples (2.5-3.0 ml) were taken from the cubital or femoral veins of animals on an empty stomach and stabilized with a heparin solution. Laboratory studies of animal blood were performed on an automatic hematological analyzer (Beckman Coulter, USA) of the CoulterAcT 5diffCP brand. In order to study the effect of water with a reduced deuterium content on hematological parameters, we determined the number of red blood cells, white blood cells, platelets, hemoglobin concentration, hematocrit, the average volume of red blood cells, red blood cell anisocytosis, and erythrocyte sedimentation rate (ESR). The metabolism trial was divided into two periods. Preliminary - to exclude the influence of previous feeding and accustoming primates to cage conditions of keeping. Experimental - conducting a thorough accounting of consumed feed, excreted excrement. Feces were collected daily at the same time (morning and evening), weighed and ground in a mortar. At each collection, 50% of the homogenized mass was taken for analysis. The collected portions were stored in the refrigerator. After the end of the experimental (accounting) period in the collected feces, the initial moisture was determined by drying at 60-70 ℃ to constant weight. The resulting air-dry mass was thoroughly ground and analyzed. It has been found that the introduction of water with a reduced deuterium content into the diet of primates has a positive effect on feed conversion rate and blood biochemical parameters.

Hematological studies were conducted in calves in dynamics during the prophylaxis of hypo-elementosis in the Amur region. The object of the study was calves (breed-Holstein, age-up to two months). The selected animals were divided into two equivalent groups: control and experimental. In the control group, planned measures were taken to prevent hypo - elementosis; in the experimental group, complex injectable drugs were used: Se-containing and tissue. Laboratory tests of calves ‘ blood were performed at the beginning and end of the experiment with determining the number of red blood cells, white blood cells, hemoglobin level, calculating the color index, differential counting of white blood cells and calculating the color index. It was established that the quality of blood oxygenation in calves of the experimental group improved. This is confirmed by the regeration to the standard values of hemoglobin level and color index as a result of their growth by 28 and 17%, respectively. At the end of the experimental period, the percentage of conditionally healthy calves was 80 % in the experimental group and 40 % in the control group. Thus, it should be noted that the proposed scheme of complex application of Se-containing and tissue preparations contributed to the normalization of erythropoiesis processes and increased the resistance of calves to diseases by 40 %.
