Abstract. The aim of the study was to determine the dose of a nanotechnological-mineral preparation based on nanosilver and vermiculite for an effective ammonia reduction, and the influence of the preparation on physical properties of litter and air. The preparation used was obtained by spreading water nanosilver suspension on vermiculite with an addition of 5 % of humodetrynite. Research animals were broiler chickens divided into three groups. The particular groups were differentiated regarding the prepared application. The measurements of ammonia concentrations were conducted in upper litter layer and about 30 cm above the litter. Litter temperature, humidity and pH, and air humidity and temperature were monitored. The measurements were conducted at day 5, 10, 15, 20 and 25 of the experiment. Ammonia content above the litter was reduced in group I and II. The highest ammonia concentration was observed in the control group at sampling four while the lowest one was noted in group II at sampling two. In all groups an influence of the preparation on ammonia content above the litter was visible. Decrease in ammonia concentration in experimental groups compared to the control group was more distinct than in the case of ammonia concentration above the litter. Based on the results it is difficult to determine unequivocally an influence of the preparation on litter temperature, pH and humidity, and also on air temperature and humidity. Taking into account the level of ammonia reduction, the results may be a premise for further studies in the range of nanosilver application for the sanitization of animal buildings.

"Linhas de pesca"* em diâmetros de 0,15mm; 0,20mm; 0,25mm; 0,30mm foram divididas em quatro grupos, contendo dez amostras de cada diâmetro: grupo I - controle; grupo II - linhas colocadas em frasco com pastilhas de formalina; grupo III - um ciclo de autoclavagem (30 minutos à 121 C, seguido por 10 minutos de secagem à 37 C em estufa); grupo IV - dois ciclos de autoclavagens. Foram avaliadas quanto: comprimento, calibre, resistência no nó e alongamento. Comparativamente foram examinados fios de náilon cirúrgico nas numerações 0, 1-0, 2-0, 3-0, 4-0 e 5-0 (10 amostras de cada um). Pelos resultados da análise estastística, verificou-se que a esterilização pelo calor úmido exerceu um efeito adverso na resistência da "linha de pesca". Por outro lado não houve diferenças na resistência, calibre e alongamento da "linha de pesca" entre o primeiro e segundo ciclo de autoclavagem. As “linhas” mantidas em pastilhas de formalina mantiveram na sua maioria suas características originais de resistência, comprimento, diâmetro e alongamento quando comparada ao grupo controle, entretanto, cabe lembrar que o formaldeído é considerado irritante para pele e membrana mucosa. Foi possível concluir que a "linha de pesca" apresenta características semelhantes ao fio cirúrgico, podendo ser mantida em pastilhas de formalina ou esterilizada em autoclave, lembrando que a autoclavagem altera algumas de suas propriedades físicas. Abstract A comparative study has been carried out between fishing lines and nylon thread in regard to their applicability as surgical thread. Four groups of 10 fishing lines in each of the following diameters = 0.15, 0.20, 0.25 and 0.30 mm = were subjected to the following treatments: group I, control; group II sterilized with formalin tablets; group III, autoclaved 30 minutes at 121oC; group IV, autoclaved twice 30 minutes at 121oC. The following parameters were then considered: length, caliber, resistance at the knot, and elongation. Ten samples of each surgical 0, 1.0, 2.0, 3.0, 4.0 and 5.0 nylon threads were used in comparatively similar experiments as the ones carried out with the fishing lines. According to the statistical analyses of the experimental results, it has been found that the sterilization by means of the humid heat exerts an adverse effect on the resistance of the fishing line. However, no differences were found between the effect displayed by two cycles sterilization compared with the fishing lines subjected to only one cycle. The threads maintained in formalin kept the majority of their original properties of resistance, length, diameter and elongation when compared with the control group. It is known, however that formaldehyde is an irritant chemical towards the skin and the mucous membranes. It was possible to conclude: a. fishing lines display characteristics similar to that ones of the nylon surgical thread; b. they can be maintained in formalin solution; c. autoclave sterilization alters some of their physical properties.

Abstract An experiment was conducted on 600 broiler chickens to determine the effect of using Camelina sativa oil as a dietary component on meat quality indicators. Broiler chickens were raised on litter under standard conditions of feeding and maintenance. In the second period of rearing, the control group (I) received a diet containing 6% rapeseed oil. Experimental groups were fed on a diet containing 3% rapeseed oil and 3% Camelina sativa oil (group II) and 6% camelina oil (group III). At the end of rearing 8 chickens from each group were slaughtered. A simplified analysis of the carcasses was conducted. Blood samples were taken to determine the content of total fat, triglycerides, total cholesterol and its fractions. Muscle samples were analysed for the content of dry matter, total protein and crude fat, fatty acid composition and malonic aldehyde (TBA). The meat was subjected to sensory evaluation. It was found that the introduction of Camelina sativa oil to the grower diet for broiler chickens does not have a negative effect on rearing parameters and carcass quality. What was observed was a tendency to reduce the proportion of abdominal fat in the carcass with increasing level of oil used in compound feed and increases in the total protein content of breast meat in group II receiving 3% of camelina oil. The addition of 6% of Camelina sativa oil to compound feed significantly decreased the content of total cholesterol and its fractions in the blood plasma of chickens in comparison to the other groups. The introduction of 3% and 6% of Camelina sativa oil to chicken diets enriched the breast meat in n-3 PUFA, mainly α-linolenic acid (ALA) and did not impair the flavour qualities of the cooked meat. The meat from chickens fed on a diet containing 6% of camelina oil was characterized by a greater increase of ALA.

The effect of different litter materials on ammonia concentration of the air ambient stall and broiler performanceABSTRACT. The study was conducted to observe the effect of ammonia concentration of broiler chicken coop air to the treatment various types of litter. High ammonia concentrations would interfere with performance of broiler chickens and become a problem for the environment. A good litter quality is expected to address the problem of ammonia that occur in the broiler chicken coop. This study uses a completely randomized, with 5 litter treatments. T0 without treatment repose only black plastic as litter, litter composition T1 100% bran, 50% T2 litter composition husks and Charcoal Shell 50%, T3 50% 50% husk litter composition and zeolite 50%, T4 25% husks litter composition, 25% charcoal, 25% zeolite and 25% of the land. Each treatment was repeated 3 times, each test consisted of eight chickens. Parameters observed in the form of ammonia concentration of air cages at week four, weekly feed intake, weight gain per week, the final weight, feed conversion, and mortality. The results indicate different types of litter treatment was very real influence of ammonia concentration of air enclosure. T4 treatment with a 1:1 blend of each component of the litter that is used successfully absorb such a large aerial ammonia, which indicates the ammonia content of the air is the smallest compared with other treatment 4. While the treatment without litter showed a very large aerial ammonia compared with the treatment. Feed consumption results also showed that the treatment that produces a small value causes ammonia to be markedly higher consumption. Values for weight gain, final weight, feed conversion, and mortality are not significantly affected by various types of litter treatment.

The health of farm poultry depends on the balance between normal and potentially pathogenic intestinal microflora. Any changes in this equilibrium are accompanied by functional impairments, which, in turn, lead to a decrease in productivity. The use of probiotics helps to avoid imbalance of intestinal microflora and death of young animals. In this connection, it is relevant to study the effects of probiotic drugs to improve the vitality and immune function of the poultry. The purpose of the research was to clarify the effect of BPS-44 and different amounts of yeast Saccharomyces cerevisiae on the activity of the humoral level of natural resistance in chicken broilers. Experiments were carried out on broiler chicks-308 grown in the Fedyuk M farm in the Zolochiv district of Lviv oblast. The maintenance of the chickens was cellular with free access to feed and water. Technological parameters of broiler cultivation (temperature and light regime) were in accordance with the norms of ONTP-2005. Experiments were conducted in 4 groups of broiler chickens of 100 chicks in each according to the scheme: the control group was fed with the standard feed (SC) according to the existing norms recommended for the ROSS-308 cross; the experimental group I in addition to the SC received a probiotic BPS-44 (registration certificate No. 2154-04-0254-06 dated November 24, 2006), based on the production strain of bacteria Bacillus subtilis ssp. subtilis 44-p, dose 0.21 g/kg, the experimental group II – 1% yeast Saccharomyces cerévisiae; the experimental group III of chickens – 2% yeast Saccharomyces cerévisiae. Blood was taken from chickens in order to carry out immunological research at different age intervals: 11, 27, 34 and 41 days of age. Blood serum was determined by bactericidal and lysozyme activity and the content of circulating immune complexes. The stimulatory effect of BPS-44 and yeast Saccharomyces cerеvisiae in the composition of mixed fodder for broiler chickens on the dynamics of the formation of humoral protection factors in the bird organism was established. At the same time, in the conditions of use of yeast Saccharomyces cerэvisiae in the composition of mixed fodder, a higher level of indices of the humoral level of non-specific resistance was recorded, than the preparation BPS-44.

The effect of dietary supplementation of selenium in an organic form on performance, carcass traits and selenium content in tissues of broiler cockerels Ross 308 was studied. The soya-wheat-maize diet contained 50 mg vitamin E/kg. The experiment was conducted on 810 straight-run broiler cockerels randomly divided into 3 groups: group I – control, without selenium supplement; experimental group: II – 0.3 mg Se/kg, Se-enriched yeast was applied as a Se source; III – 0.3 mg Se/kg, Se-enriched alga Chlorella as a Se source. The broiler chickens were slaughtered at 42 days of age. In performance traits higher (P ≤ 0.05) live weight of broiler chickens was recorded in the experimental groups (II – 2 430.6 g and III – 2 425.2 g). There were no significant differences between the groups in feed conversion and mortality. Se-enriched alga had the best feed conversion, and selenium supplementation slightly increased mortality in both experimental groups. No significant differences between the groups were found out in carcass traits and dressing percentage. The content of selenium in breast and thigh muscle, feathers and excrements increased (P ≤ 0.05) in both experimental groups compared to the control group. Higher values in breast and thigh muscle and in feathers were measured in the group supplemented with selenium from Se-enriched yeast, also in comparison with the group supplemented with selenium from Se-enriched alga Chlorella. The broiler chickens receiving Chlorella had a higher (P ≤ 0.05) selenium content in excrements compared to the group with Se-enriched yeast. The selenium concentration in liver was higher (P ≤ 0.05) in both experimental groups compared to the control. The supplement of selenium from Se-yeast and Chlorella in the diet for broiler chickens increased the microelement concentration in muscle.

Introduction. In recent years, the production of feed additives of animal origin in Ukraine has declined sharply, and the cost of imported additives is very high. At the same time, in our country, the industry of industrial poultry farming has recently received intensive development, in particular, the cultivation and processing of broiler chickens for meat. At the same time, a significant amount of non-food waste from poultry slaughter in many poultry farms is not processed for feed purposes. Currently, an urgent problem is the organization of processing of non-food waste of poultry for feed purposes at poultry farms of industrial type of cultivation for meat of broiler chickens, primarily from blood and hydrolyzed raw materials. Processing of these wastes for feed purposes will not only give the opportunity to increase the production of high-grade protein feed, but also to significantly improve environmental safety. The purpose of our research is to study the meat productivity, safety, slaughter yield and quality of broiler chicken meat when feeding a combined feed additive from blood and hydrolyzed raw materials. Materials and methods of research. Development of an innovative technological line for the production of a combined feed additive from blood and hydrolyzed raw materials was carried out in LLC "Complex Agromars" (village of Havrylivka, Vyshgorod district of Kyiv region), and research on the effectiveness of feeding a combined feed additive from blood and hydrolyzed raw materials was performed in the production conditions of LLC "Bila Hora" Sniatynskyi district of Ivano-Frankivsk region. Research result. Development of innovative technological line was carried out in cooperation with engineering and technical staff of LLC "Complex Agromars". The innovative technological line is designed and installed using devices and mechanisms of the company "Haarslev Industries". In order to study the effectiveness of feeding a combined blood-feather feed additive for the experiment, four groups of broiler chickens of the Cobb 500 cross were formed, 50 heads in each, according to the following scheme: one group of broiler chickens was taken as a control group, and the next three groups – as research groups. Cultivation of broiler chickens in the experiment was carried out according to the traditional technology of feeding on standard compound feeds adopted in industrial broiler poultry farming, which, depending on the age and growth of chickens, includes 3 phases: "Start" – 14 days, "Growth" – 18 days, "Finish" – 12 days. According to the scheme of experience, the control group of chickens received standard feed without blood-feather feed additive. The difference in feeding of the broiler chickens of the experimental groups was in different levels of feeding with experimental combined feed additive from blood and hydrolyzed feather raw materials, which, depending on the age and growth of chickens, included in the feed of the I group from 4 to 12%, of the II group – from 3 to 10%, of the III group – from 2 to 8%. As a result of the studies it was found that at the end of the experiment at 44-day age the average live weight of broiler chickens of the control group was 2630 g, of the experimental group I – 2885 g, of the group II –2790 g, of the group III – 2680 g. For 44 days of experience the following amounts died: in the control group – 2 chickens, in the experimental group I – 1 chicken, in the group II – no chickens, in the group III – 1 chicken. Slaughter of broiler chickens and meat tasting was carried out in the company "Bilyi Bereh" of Ternopil region at the age of 44 days. It was established that the average slaughter yield of 1 carcass of broiler chicken meat was: in the control group – 1920, in the experimental group I – 2106 g, in the group II – 2037 g, in the group III – 1956 g. The difference in quality of meat of broiler chickens of control and experimental groups by results of tasting was not revealed. Summary: In LLC "Complex Agromars" (village of Havrylivka, Vyshgorod district of Kyiv region) designed and implemented an innovative technological line for production of ecologically safe combined feed additive from blood and hydrolyzed feather raw materials from non-food waste slaughter of broiler chickens when growing for meat. In the course of scientific and economic experiment it was found that the inclusion in the standard traditional feed in different phases of cultivation of broiler chickens for meat of about 4 to 12% of the combined feed additive from blood and hydrolyzed feather raw materials increased their average live weight from 2630g in the control group to 2885 g, and the average slaughter yield of 1 meat carcass – from 1920 g in the control group to 2106 g.

Abstract Faba bean (FB) seeds can be a good protein-energy component in animal feed. However, the presence of anti-nutritional substances is a negative feature of FB seeds. The aim of this study was to examine the influence of different levels of unprocessed FB seeds in feed on the gut-bone axis and metabolic profile in broilers. Ninety six, 1-day-old Ross 308 broiler chickens were randomly selected to one of the 3 dietary treatments (32 chickens in each, divided into 8 pens with 4 birds per each pen): the control group fed standard diet with soybean meal and without FB seeds, group I fed 8/15% (starter/grower) of high-tannin FB seeds, and group II fed 16/22% of high-tannin FB seeds. Bone mechanical examination, hematological and serum biochemical analysis as well histomorphometry of small intestine and liver tissue were performed. The intake of high-tannin FB seeds, irrespective of their amount, did not alter the bone geometric, mechanical and densitometric parameters nor influenced basal hematological parameters, however it resulted in: decreased serum concentration of total cholesterol and calcium; a reduced longitudinal myenteron of small intestine; increased mucosa and villus epithelium thickness, villus length, thickness and absorptive surface in duodenum; increased number of active crypts in jejunum; unchanged collagen area, intercellular space, and total cell number in the liver; decreased number of multinuclear hepatocyte cells. Moreover, the livers of birds fed the higher dose of high-tannin FB seeds had lymphocytic infiltrates in portal tracts and sinusoids. Feeding of unprocessed high-tannin FB seeds exerted an influence on the gastrointestinal tract by increased absorptive surface. In conclusion, the dietary inclusion of unprocessed high-tannin FB seeds had no negative effects on broiler growth, tibial bone mechanical properties and intestinal characteristics. Unprocessed high-tannin FB seeds may be used in broiler diets, but their dietary levels should not be higher than those discussed.

In poultry farming is increasing effort to increasing profitability and decreasing of feed cost. Behind the components that are part of the mixture, the most of cost makes processing of nutrients. Extrusion is process which is increasingly used in order to enhance the quality of different feed for poultry. The aim of this research was comparative testing of nutritional value of extruded and nonextruded corn in nutrition of broiler chicken. The experiment was conducted under experimental growing conditions, in duration of 42 days. The following parameters were measured: growth, feed intake and vitality of broilers. The experiment was divided into two groups of chickens hybrid Ross-308, which were grown separately by sex with 8 replication. The first group was fed standard pelleted mixtures for growing chickens, in which the entire amount of corn in the mixture was extruded, and the second, control group was fed the same food in which corn was not extruded. In the second week of rearing the body weight was 437 g in both groups. In 4th week of age the average body weight was 1439g in group I, and 1419 in group II. For the first group conversion was 1,69 and for the second it was 1,71. The final body weight amounted 2595g for the first group and 2609 for the control group. In the first group conversion was 1,91, mortality 4,39% and the production index had a value of 309, and in the second 1,92; 4,56% and 306. In this study excellent production effects were achieved, so it was not expected that extrusion could achieve better production effects. These results showed that extrusion process does not always give the expected effects.

Abstract We studied the dietary effects of probiotic and fisetin supplementation on performance parameters, carcass characteristics and small intestinal morphology in broiler chickens. Sixty (one-day-old) Arbo Acre breed of broiler chickens were allotted into 4 groups of 15 each randomly: Group I, Control was administered only distilled water; Group II, fisetin (5 mg/kg); Group III, probiotic (4.125×106 cfu/100 mL); and Group IV, probiotic and fisetin (4.125×106 cfu/100 mL and 5 mg/kg, respectively) for the first one week of life. All administrations were performed orally through gavage. Broiler chickens supplemented with probiotic and probiotic+fisetin had greater feed intake significantly (P<0.05) at weeks 5 and 6, when compared respectively with those of the control and fisetin groups which had lesser feed intake values. Body weight gain was of great significance (P<0.05) in the probiotic-supplemented broiler chickens, while that of the control was less. Carcass quality of the probiotic-supplemented group was higher in significance (P<0.05) than any other treatment group which had lower qualities. The pH changes in the breast muscle was lesser significantly (P<0.05) in the probiotic+fisetin group, when compared with those of the control group which had greater changes. The villus height/crypt height ratio was higher in significance (P<0.05) in the treatment groups, while that of the control group was lower. In conclusion, dietary supplementation of probiotic may enhance broiler chickens’ productivity, by improving performance, carcass weight, pH, and small intestinal morphology as compared to fisetin supplementation.
