The purpose of our research was to study the effects of dietary addition of Clostridium butyricum (CB) on performance, immunocompetence and digestive function of poultry. Using single factor experiment design, 720 one-day-old and healthy AA broilers were divided into 6 groups with 6 replicates in each group and 20 broilers in each replicate. Broilers in control group were fed a basal diet, while broilers of other experimental group were fed the basal diet supplemented with CB 250 mg/kg, 500 mg/kg, 750 mg/kg, 1000 mg/kg and 1250 mg/kg. The results showed as follows: The 1000mg/mg group had the best effect on immunity enhancement, with the thymus index, spleen index and bursa index increased by 18.38 % (P < 0.05), 16.00 % (P < 0.05) and 8.03 % (P > 0.05) in 1–21 days, and 6.45 % (P < 0.05), 12.92 % (P < 0.05) and 13.94 % (P < 0.05) in 22–49 days. The 1000 mg/kg group and 1250 mg/kg group had the best effect on improving the digestive function, with the VH/CD value increased by 27.56 % (P < 0.05) and 29.56 % (P < 0.05) in 1–21 days, and 29.48 % (P < 0.05) and 30.80 % (P < 0.05) in 22–49 days, with the number of harmful bacteria Escherichia coli and Salmonella decreased significantly (P < 0.05). These results indicated that the addition of CB in diets of broiler can improve the production performance, enhance immunity and improve digestive function, and the optimal dosage is 1000 mg/kg.

An experiment was conducted to investigate the effect of supplementing of exogenous phytase enzyme on productivity of commercial broilers. Four strains of commercial broiler such as Fast feather, Arbor acres, Cobb-500 and Hubbard classic each having 78 numbers were reared for a period of 5 weeks. A total number of 312 day old broiler chicks were distributed into two dietary treatments i.e. basal diet (Control-T0) and basal diet supplemented with phytase enzyme 1g/kg feed (supplemented-T1). The results indicated that broilers fed on diets supplemented with phytase have gained more body weight when compared with control group (P<0.05). The first and second highest body weights were recorded for the strains Cobb-500 and First feather broilers, respectively, which feed on diet containing phytase.   Feed consumption varied significantly between the broilers on different dietary regimes. Significant differences (P<0.01) were found in feed conversion ratios among the birds fed on diet with phytase enzyme. The lowest feed conversion ratio was in Cobb-500 fed on phytase diet where as the highest was in Fast Feather provided with only basal diet during the 5th week of age. Average feed conversion ratios were 1.73 and 1.86 for the supplemented and control group respectively. Use of phytase as feed additive in the diet resulted in high profitability/ broiler. Net profit per live broiler was the also higher in treatment group compared with control groups of birds. The highest net profit per live broiler was observed in Arbor Across strains fed on phytase diet. The result of the present study suggests that the addition of dietary phytase enzyme in the diet of broiler may increase the production performance and reduce the cost of production.Bang. J. Anim.

The main approach to curbing mastitis is to prevent the entry of microorganisms from the outer environment into the mammary gland, which is achieved by the use of papilla disinfection following every time of milking. The objective of this work was to examine the antimicrobial activity of the disinfectant dodicin hydrochloride, in fact the preparation that contains this disinfectant (DESU? M), against bacteria, the most frequent causes of mastitis in cows. The efficacy of modified DESU? Mwas examined under laboratory conditions using the quantitative test against the following microorganisms: Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae and Streptococcus uberis, under the conditions in the field. The udders of an experimental group of 20 cows of the Holstein-Friesian breed were immersed in a solution of the modified preparation DESU ? M following every time of milking over a period of three months. In the second group of 10 cows of the Holstein-Friesian breed, marked as the control group, no disinfection was applied following the milkings. The preparation DESU? Mexhibited satisfactory antimicrobial efficacy against the most frequent causes (Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae and Streptococcus uberis) of mastitis in cows under laboratory conditions. With the application of the preparation DESU? M, following every time of milking over a period of three months, the number of somatic cells was reduced by almost one half in comparison with their number at the start of the experiment. No residue of the modified preparation DESU ? M were found in any sample of milk from the experimental group of cows.

Probiotics are a group of active microorganisms, which benefit the host by colonizing and changing the composition of host flora. It is of great significance to promote the development of human gastrointestinal nutrition and health by regulating the host mucosal and systemic immune function or regulating the balance of intestinal flora. The purpose of this study is to analyze the production activity of the enzyme, evaluate its biological characteristics and safety as a preventive drug, and provide reference for the research of enzyme production and compound enzyme preparation by probiotics. In this study, four groups of probiotics were set up: Clostridium butyricum experimental group, Lactobacillus plantarum experimental group, drinking water control group, and Bacillus licheniformis experimental group. In addition, a variety of complex enzyme experiments were set up to study the influence on the digestive tract and single factor experiment. The results showed that probiotics and compound enzyme preparations could significantly promote the intestinal digestibility. Under the effect of probiotics, the weight of the chicken was almost 1 Jin heavier than that of the control group, and the average digestibility was increased by 4.3%. The effect of the enzyme on digestibility is stronger than that of probiotics, but the final effect tends to be stable.

Forty female chickens were allocated to four groups of ten birds each. The control group (K) was fed a basal diet without supplementation. The second control group received a basal diet with humic acid (HA) at a dose of 0.5 g per chicken/day. The first experimental group was fed the basal diet with methyl-mercury (MeHg) at a dose of 0.02 mg per chicken/day and the group of chickens MeHg + HA received 0.5 g HA per chicken/day. After slaughter, mercury levels were assessed in liver, kidney, brain and muscle tissue samples. After 10-day treatment of the chickens with MeHg, significantly increased (<I>P</I> < 0.001) Hg concentrations were detected in all examined tissues in comparison with the groups K and HA. The average concentrations in liver, kidneys, brain and muscle tissues were 424, 398, 81.6 and 79.2 µg Hg/kg, respectively. After concurrent treatment with HA and MeHg, Hg concentrations were lower by 20.6%, 23.8%, 23.0% and 18.6% in liver, kidneys, brain and muscle tissues (<I>P</I> < 0.001). Biological accumulation of Hg was 25.5% and 20.4% in MeHg and MeHg + HA groups, respectively.

AbstractThe aim of this study was to determine the percentage of participation of particular species of microorganisms, isolated from the uterus of cows with endometritis and from cows without inflammatory lesions of the uterus, in the same postpartum period. The aim of the study was also to examine how long after parturition non-treated endometritis persists. Moreover, antibiotic susceptibility tests were carried out of the bacterial isolates dominating in the uterus. Forty cows were included in the study: 20 cows with endometritis (experimental group) and 20 cows without any inflammatory condition of the uterus (control group). The material for cytological and bacteriological tests was collected on the 5th, 26th, 40thand 60thday after parturition, using an intrauterine brush adapted for cows. The total number of collected isolates was 149, including 120 isolates from the uterus of cows with endometritis and 29 isolates from the uterus of cows without endometritis. The following species of microorganisms were isolated from the material collected from cows with endometritis: T. pyogenes (49.2%), E.coli (22.5%), F. necrophorum (11.7%), Staphylococcus sp. (6.7%), B. melaninogenicus (5.8%), and Streptococcus sp. (4.1%). The participation percentage of particular species of bacteria in the material collected from the uterus of cows without endometritis was as follows: T. pyogenes (27.6%), E.coli (24.2%), Staphylococcus sp. (20.7%), Streptococcus sp. (20.7%), B. melaninogenicus (3.4%) and F. necrophorum (3.4%). The highest percentage of T. pyogenes isolates was susceptible to ceftiofur (89.6%); cefoperazone (85.1%) and amoxicillin combined with clavulanic acid (79.1%). E. coli isolates were most susceptible to amoxicillin combined with clavulanic acid (100%), cefoperazone (94.1%) and oxytetracycline (82.3%).

The article gives scientific substantiation of using silicon-containing new feed additive “Energosil” for replacement gilts. The studies were conducted in pig-breeding complex of the Center for Practical Training of Agricultural Specialists in Mordovia Republic. There were three experimental groups of replacement gilts (10 animals each). The effect of various dosages of Energosil (5.0, 7.5, and 10 mg per kg of body weight) on digestibility, nutrient utilization, and animal growth energy was studied. The most optimal dosage of a new feed additive in their rations was revealed, which constituted 5 mg / kg of the animal live weight. It was established that the animals from the first experimental group, who received silicon-containing feed additives of this amount digested the nutrients of the diet better than their counterparts from the other groups. Compared to the control group, the digestibility of dry matter increased by 3.62% (p<0.05), organic matter by 3.29% (p<0.01), crude protein by 4.09% (p<0.001), fat by 4.30% (p<0.01), cellulose by 3.79% (p<0.01) and nitrogen-free extractives by 2.03% (p>0.05).Replacement gilts of the first experimental group, who were given Energosil in the amount of 5 mg / kg body weight in addition to the basic ration, retained nitrogen in their bodies by 17.1%, calcium by 55.9% and phosphorus by 69.7% more than their counterparts from the control group. It contributed to an increase in body weight of gilts from the first group compared to control counterparts by 10.8%. Increased dosages of Energosil (7.5 and 10 mg / kg body weight) also had a better effect on the growth energy of gilts compared with the control group. The feed additive in the amount of 7.5 mg kg of animal  live weight contributed to an increase in animal weight compared with control counterparts by 6.21 kg or 4.8% (p<0.05), with a third experimental group by 4.4 kg or by 3.4% (p<0.05). When given Energosil in the dosage of 10 mg/kg, the body weight of gilts from the third experimental group was higher by 1.81 kg or 1.4% (p> 0.05) compared with the control counterparts.

Abstract The study was designed to investigate the effect of mannan-oligosaccharide (MOS) supplementation on intestinal histomorphology, immunity against Newcastle disease virus (NDV) and productive parameters of broilers. A total of 1800 day old broiler chicks of Cobb-500 strain were selected and randomly assorted into 6 treatment groups: T1 (basal diet without antibiotics as negative control); T2 (basal diet plus antibiotics as positive control group); T3 (basal diet plus 200g/ton MOS); T4 (basal diet plus 400g/ton MOS); T5 (basal diet plus 600g/ton MOS) and T6 (basal diet plus 800g/ton MOS). Each treatment was having 6 replicates and the feed intake, body weight gain and feed conversion ratio (FCR) were recorded on weekly basis. Results showed that, MOS supplemented birds have significantly higher feed intake, weight gain and FCR (P < 0.05). Similarly, supplementation of MOS showed positive effect on villus height and crypt depth both in jejunum and ilium. Goblet cell density was unaffected by MOS addition (P < 0.05). Furthermore, birds fed with diets containing MOS, exhibited better productive performance in comparison to positive and negative control groups. In conclusion, MOS can replace antibiotic growth promoters (AGPs) as non-microbial performance-enhancing feed advocates.

The current study investigated the effect of dietary supplementation with probiotics and Yucca schidigera extract on physicochemical parameters, proximate composition, mineral content and fatty acid profile of broiler breast and thigh muscles. In total, 240 one-day old broilers were randomly allocated into two dietary treatments groups: 1) Control (basal diet), 2) experimental (basal diet with two probiotics Pediococcus acidilactici and Saccharomyces cerevisiae and Yucca schidigera extract). The results showed that the pH value was higher in the experimental group than in the control group (p < 0.05). However, drip, cook and thaw losses were not influenced by dietary treatment (p > 0.05). A significant increase in protein, Fe, Zn, Na, P and a significant decrease in lipid, Cu and Cr contents was exhibited in experimental group relative to control group (p < 0.05). The proportion of stearic acid and saturated fatty acids was significantly (p < 0.05) reduced, whereas linoleic acid and polyunsaturated fatty acids contents were significantly (p < 0.05) increased in breast and thigh muscles of fed the experimental diet. We concluded that additive supplementation of the diet with probiotics and Yucca schidigera extract could improve meat quality.
