The Impact

The study was performed to evaluate the effect of a dietary level of two types of inulin differing in the degree of polymerization (DP), supplemented at different levels, on selected metabolic and immunological parameters of broiler chicken blood. Two hundred and forty 1-day-old broiler chickens were fed a diet without inulin addition (control group, C) or with standard inulin from chicory root with DP ≥ 10 (SI) or long-chain inulin (LCI) of DP ≥ 23 (Inulin Orafti®GR or Inulin Orafti®HPX, respectively; Orafti Beneo GmbH, Mannheim, Germany) at a level of 0.2%, 0.4%, or 0.6%. Therefore, 7 dietary treatments were formed. The experiment was carried out for 6 weeks. The addition of inulin had a significant (p ≤ 0.05) impact on the blood parameters analyzed, especially on the protein and lipid profile. The degree of polymerization of inulin and its level in the diet significantly affected the content of glucose and uric acid and creatinine levels in the blood plasma of 21-day-old chickens. The addition of the different types (SI vs. LCI) and levels (0.2, 0.4, and 0.6) of inulin to the diet and the interaction of these factors affected the total protein level and the content of albumins and globulins. Some differences (p ≤ 0.05) were found between the experimental groups in total cholesterol and its HDL fraction content as well as in the activity of ALT and LDH. The other biochemical indices were not affected by the experimental factors. In conclusion, it may be stated that inulin with the higher polymerization degree (LCI; DP ≥ 23) provided better results of the blood metabolic profile throughout the broiler fattening period. However, the impact of this factor is not explicit. The addition of the inulin extract at an amount of 4-6 g per kg of mixture is recommended, but further experiments are recommended....

A 49-day experiment was conducted with a total of 240 Arbor acre broiler chicks, to determine the effect of probiotic supplementation on graded levels of shea kernel cake meal (SKCM) on their haematological and serum biochemical indices. The birds were randomly grouped into four dietary treatments comprising of 0%, 5%, 10% and 15% inclusion levels of SKCM as T1 , T2 , T3 and T respectively in a completely randomized design having 5 replicates with 12 chicks each. Diet T served as the control, without SKCM and probiotic addition, while diet T2 , T3 and T4 were supplemented with 0.5g/kg Biovet-YC® at both starter and finisher phases. Feed and water were given ad-libitum and routine management were strictly observed. At the end of the feeding trial, three broilers per replicate were randomly selected and blood collected using hypodermal syringe into two different labeled bottles with or without an anti-coagulant (EDTA) for haematology and serum biochemistry investigation respectively. The results showed that there were significant (P<0.05) increase in the white blood cell count and corresponding decrease (p<0.05) in serum triglyceride and cholesterol concentration of birds fed probiotic supplemented SNCM diets. However, other blood parameters measured were not affected (p>0.05) by the probiotic supplementation. Therefore, it can be concluded that incorporation of probiotic supplemented SKCM up to 15% inclusion level did not have any deleterious impact on blood status of the broilerchickens.

In this study, a total of 200 male broiler chickens (Ross 308) were assigned to four dietary treatments (5 pens/treatment and 10 birds/pen) for two feeding phases: starter (0–11 days of age) and grower-finisher (11–33 days of age). A basal diet containing soy oil (SO) as added fat was used as control group (C), tested against three experimental diets where the SO was partially substituted by BSF larvae fat (BSF) or one of two types of modified BSF larvae fat (MBSF1 and MBSF2, respectively). The two modified BSF larvae fats had a high and low ratio of monobutyrin to monoglycerides of medium chain fatty acid, respectively. Diet did not influence the growth or slaughter performance, pH, color, or the chemical composition of breast and thigh muscles, gut morphometric indices, or histopathological alterations in all the organs. As far as fecal microbiota are concerned, MBSF1 and MBSF2 diets reduced the presence of Clostridium and Corynebacterium, which can frequently cause infection in poultry. In conclusion, modified BSF larva fat may positively modulate the fecal microbiota of broiler chickens without influencing the growth performance and intestinal morphology or showing any adverse histopathological alternations.

Cefotaxime (CTX)-resistant Enterobacteriaceae are still an ongoing challenge in human and veterinary health. High prevalence of these resistant bacteria is detected in broiler chickens and the prevention of their dissemination along the production pyramid is of major concern. The impact of certain on-farm interventions on the external bacterial contamination of broiler chickens, as well as their influence on single processing steps and (cross-) contamination, have not yet been evaluated. Therefore, we investigated breast skin swab samples of broiler chickens before and during slaughter at an experimental slaughter facility. Broiler chickens were previously challenged with CTX-resistant Escherichia coli strains in a seeder-bird model and subjected to none (control group (CG)) or four different on-farm interventions: drinking water supplementation based on organic acids (DW), slow growing breed Rowan × Ranger (RR), reduced stocking density (25 kg/sqm) and competitive exclusion with Enterobacteriales strain IHIT36098(CE). Chickens of RR, 25 kg/sqm, and CE showed significant reductions of the external contamination compared to CG. The evaluation of a visual scoring system indicated that wet and dirty broiler chickens are more likely a vehicle for the dissemination of CTX-resistant and total Enterobacteriaceae into the slaughterhouses and contribute to higher rates of (cross-) contamination during processing.

AbstractThe primary aim of this study was to investigate the impact of three dietary levels of lactose (LAC) originating from conventional dried whey (DW) and the duration of these treatments (from 8 to 21 or to 42 days of age) on growth performance, basic post-slaughter traits and excreta quality of broiler chickens kept in cages. A secondary purpose was to investigate the effect of LAC level on some parameters of the caecal micro-environment and gross morphology in these birds. A total of 560 Ross 308 chickens (sex ratio 1:1) were assigned to 7 dietary combinations with 10 replicate cages of 8 birds per cage. The control group was fed basal diets consisting of maize, wheat and soybean meal. The other 6 groups received the same basal diets with DW added in amounts equivalent to a LAC dietary levels of 1, 2 or 3%. Only continuous feeding (day 8 to 42) with 1% and 2% levels of LAC was found to yield the overall body weight gain (BWG) during the whole 42-day rearing period, which was significantly higher than that on the control diet, with a larger share of breast meat in carcass at a 2% LAC. However, these effects were associated with greater faecal score values indicating more watery excreta compared with the control. Increasing levels of LAC augmented the relative caecal weight and length. A reduction in the caecal pH was confirmed at day 21 for birds fed 1% and 2% of dietary LAC. The lower pH values were correlated to an increased sum of total volatile fatty acids (VFA), causing large increases in the concentration of undissociated forms of individual VFA. The decline in plate counts of coliform bacteria was observed with 2% and 3% LAC, whereas the counts of lactic acid-producing bacteria (LAB) were higher at these two LAC levels. The present findings lead to the conclusion that the dietary level of 2% LAC originated from DW is the most effective in enhancing the productivity of broilers, with moderate occurrence of undesirable side effects.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

This study was to evaluate the effects of supplementation of ethanol extracts of chive (CE) and ginger (GE), and their combination (CG) in diets of broiler chickens on their growth, health performance and economic efficiency. Totally 180 male Egyptian broilers from one-day age were randomly assigned to 6 dietary treatments consisting of 3 replicates of 10 chicks each, of which in the diet of the control group (CT) neither ginger nor chive preparation were introduced, meanwhile the diets of birds in the 5 trial groups (CE1, CE2, GE1, GE2 and CG) were supplemented with 0.5% CE, 1% CE, 0.5% GE, 1% GE and 0.5% CE plus 0.5% GE preparations, respectively. In general, supplementation of CE and GE did not significantly affect feed consumption, mortality, performance efficiency index (PEI), and respiratory syndrome in chickens. However, the herb extract preparations could reduce the incidence of diarrhea in broiler chickens during five to-ten-week age periods. Microscopic examination of small intestinal mucosa showed that the heights of villi and the depths of crypts of chicks in the CE2 treatment as well as the diameters of villi of chicks in the CG treatment were significantly (p < 0.05) higher than in the others. In general, supplementation of 1% CE and the combination of 0.5% CE and 0.5% GE preparations improved the growth performance of broilers, and the combination can be an alternative to antibiotics as growth promoters in feeding chicken.

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

A total of 100 one-day-old healthy broiler chicks were used to study the effects of lincomycin and bacitracin on some hematobiochemical and immunological parameters. Chicks were divided into four equal groups, 25 each. The first group was kept as control; the 2nd group was received 0.5 g of lincomycin per liter; the 3rd group was received 100 mg bacitracin per liter and the 4th group was administered both lincomycin and bacitracin, each at the above-mentioned dose. Drugs were given in drinking water for 5 successive days from 20th to 25th day of age. Bodyweight was recorded at the beginning of the experiment and at 1st-day post administration where body performance was recorded. One day post administration, blood samples were collected for estimation of hematobiochemical and immunological alterations. The obtained results revealed that broiler chicks administered lincomycin or bacitracin or both revealed a marked increase in bodyweight, weight gain, phagocytic activity, phagocytic index, erythrocytic count, hemoglobin level, packed cell volume, total leukocytic count, serum total protein, albumin, total globulin, α, β and γ globulin. Furthermore, a significant elevation in malondialdehyde associated with a marked reduction in albumin-globulin ratio, serum total lipid, cholesterol and triglyceride and a significant decrease in catalase and superoxide dismutase, were recorded, compared with the control group. In conclusion, lincomycin and bacitracin either alone or in combination have positive impacts on growth performance, immunological and hematobiochemical parameters of broiler chickens. So, it is recommended to use both drugs as growth promoters in broiler chickens.

This study was performed to evaluate the comparative effects of dietary supplementation of dried purslane powder (PP), purslane aqueous extract (PAE) and purslane methanolic extract (PME) on performance, antioxidant status, carcass traits and selected plasma lipid parameters in broiler chickens. In total, 420 1-day-old male broiler chicks were divided into seven treatments for 49 days as follows: control (basal diet), basal diets plus 1500 or 3000 mg/kg of PP (PP1500 and PP3000 respectively), basal diets plus 150 or 300 mg/kg of PAE (PAE150 and PAE300 respectively) and basal diets plus 150 or 300 mg/kg of PME (PME150 and PME300 respectively). During the total period of the experiment (0–49 days of the experiment), birds receiving the PP3000 diet had higher (P &lt; 0.05) bodyweight gain and a lower feed conversion ratio compared with those fed other diets. At 24 and 49 days of the experiment, birds receiving the PP3000 diet showed greater (P &lt; 0.05) plasma and liver activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx), and lower (P &lt; 0.05) plasma and liver levels of malondialdehyde compared with other dietary treatments. Additionally, at 24 days of the experiment, birds receiving the PP3000 diet had a greater (P &lt; 0.05) liver catalase activity than those receiving other dietary treatments. In addition, groups receiving the PP1500, PAE300 or PME300 diets showed greater (P &lt; 0.05) plasma and liver activities of superoxide dismutase, catalase and glutathione peroxidase, as well as lower (P &lt; 0.05) plasma and liver levels of malondialdehyde compared with the control group. At 24 days of the experiment, birds receiving the PP1500 or PP3000 diets showed greater (P &lt; 0.05) jejunal activities of superoxide dismutase, catalase and glutathione peroxidase than other groups. At 49 days of the experiment, birds receiving the PP3000 diet showed greater (P &lt; 0.05) jejunal activities of superoxide dismutase and glutathione peroxidase compared with the control group. Additionally, at both 24 and 49 days of the experiment, groups receiving the PP3000 diet had lower (P &lt; 0.05) jejunal levels of malondialdehyde compared with the control group. At 49 days of the experiment, birds receiving the PP3000 diet had a lower (P &lt; 0.05) relative weight of abdominal fat compared with those receiving the other dietary treatments. Moreover, groups that consumed the PP1500, PAE300 or PME300 diets showed lower (P &lt; 0.05) relative weights of abdominal fat compared with the control group. Groups fed PP, PAE or PME treatments showed lower (P &lt; 0.05) plasma levels of triglycerides, total cholesterol and low-density lipoprotein cholesterol, and higher (P &lt; 0.05) plasma levels of high-density lipoprotein cholesterol than the control group at 24 and 49 days of the experiment, with the most pronounced effects observed in those receiving the PP3000 treatment. In conclusion, PP showed more beneficial effects than PAE and PME, and 3000 mg/kg was the best inclusion level of PP in broiler chicken diets.

AbstractA total of 608 Ross 308 broiler chickens of both sexes were studied to determine the effect of Lactococcus lactis 847 bacteria compared to probiotic bacteria Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 on body weight, feed consumption and conversion, mortality, dressing percentage, postmortem carcass traits, composition of breast muscle tissue, and blood plasma traits. Feeding diets with bacteria to chickens did not increase body weight at 42 days of age or improve feed conversion compared to control chickens. It significantly reduced chicken mortality compared to the control group, from 3.3% to 1.4% (P<0.01). No significant differences were found in feed consumption and conversion. There were no significant differences in the weight of carcasses and their parts. Lactococcus lactis 847 and Lactobacillus plantarum 837 bacteria significantly increased dressing percentage (P<0.05). Lactococcus lactis 847 significantly increased liver weight (P<0.05). No significant differences were observed in carcass fatness, and in the dry matter, protein and fat content of breast muscles. Feeding diet with Lactobacillus plantarum 837 to chickens significantly decreased plasma triglyceride levels, and feeding diet with Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 significantly decreased the level of high-density cholesterol (P<0.05). In conclusion, Lactococcus lactis 847 bacteria in diet significantly reduce losses due to digestive disorders while having no effect on the quantity and proportion of saleable cuts in the carcass, the composition of breast muscles and basic blood parameters.
