The use of betaine can influence the resistance, production performance and quality of broiler carcass, and potentially it can reduce the need for choline and methionine in food due to the mutual correlation of these three substances in the organism. Objective of the paper was to investigate the effect of full substitution of added DL-methionine with betaine in diets for broilers on production and slaughter parameters in conditions of optimal amount of choline in the feed. Study was carried out on 1725 one day old broiler chickens of Cobb 500 hybrid divided into 3 groups: Control group (C) fed complete forage mixtures with usual addition of DL methionine and two trial groups where methionine was substituted by 1g (B1group), and by 2g of betaine per kilogram of mixture (B2 group). Research results indicate that the full substitution of supplemented methionine with betaine in feed can have positive and negative impact in broiler fattening. Negative effects on final body mass, gain and feed conversion were determined in broilers fed mixtures where 1g of synthetic methionine was replaced with 1g of betaine preparation, and at the same time positive influence on mortality was observed, especially in broilers fed diets containing 2g of betaine. Production index showed no significant differences between trial groups, as well as studied broiler carcass quality parameters.

Abstract Background Intestinal epithelial cells are challenged by mycotoxins and many bacterial pathogens. It was previously shown that the mycotoxin deoxynivalenol (DON) as well as Campylobacter (C.) jejuni have a negative impact on gut integrity. Recently, it was demonstrated that DON increased the load of C. jejuni in the gut and inner organs. Based on this finding, it was hypothesized the DON metabolite (deepoxy-deoxynivalenol, DOM-1) should be able to reduce the negative effects of DON on colonization and translocation of C. jejuni in broilers, since it lacks the epoxide ring, which is responsible for the toxicity of DON. Methods A total of 180 broiler chickens were housed in floor pens on wood shavings with feed and water provided ad libitum. Birds were divided into six groups (n = 30 with 5 replicates/group): 1. Control, 2. DOM-1, 3. DON, 4. DOM-1 + C. jejuni, 5. DON + C. jejuni, 6. C. jejuni. At day 14, birds of groups 4, 5 and 6 were orally inoculated via feeding tube (gavage) with 1-ml of a PBS suspension containing 1 × 108 CFU of C. jejuni NCTC 12744. The performance parameters: body weight (BW), body weight gain (BWG), and feed intake of the birds were determined. At 7, 14, and 21 days post infection, samples from liver, spleen, duodenum, jejunum and cecum were aseptically collected and processed for bacteriological investigations. Finally, at each killing time point, segments of duodenum, jejunum and cecum were harvested and prepared for Ussing chamber studies to measure the paracellular mannitol fluxes. Results A significant decrease in body weight was observed for chickens receiving the DON diet with or without C. jejuni compared to the other groups. Furthermore, it was found that the co-exposure of birds to DON and C. jejuni resulted in a higher C. jejuni load not only in the gut but also in liver and spleen due to increased paracellular permeability of the duodenum, jejunum and cecum. On the contrary, DOM-1 supplementation in the feed improved the birds’ performance and led to a better feed conversion ratio throughout the trial. Furthermore, DOM-1 did not negatively affect gut permeability and decreased the C. jejuni counts in the intestine and internal organs. Conclusion Altogether, the presence of DOM-1 in the feed as a result of the enzymatic biotransformation of DON leads to a lower C. jejuni count in the intestine and better feed conversion ratio. Moreover, this study demonstrates that the detoxification product of DON, DOM-1, does not have negative effects on the gastrointestinal tract and reduces the Campylobacter burden in chickens and also the risk for human infection.

Abstract Climate change and the lack of conventional feed ingredients have made edible insects a highly nutritious alternative to feed production. The use of insects as food may help solve socio-economic and environmental problems around the world and be in line with the United Nations Sustainable Development Goals. In this study, the growth performance and intestinal morphology of broiler chickens were evaluated under the influence of adding different levels of Tenebrio molitor larvae meal (TM meal) to their diets. One hundred eighty day-old broiler chickens were divided into 3 treatments and 5 replications (12 chickens/pen). The experimental diets included a control diet and treatments containing 2.5 and 5% TM meal, which were fed to birds in the starter (0-10 days) and grower (11-25 days) stages, and during the final period (26-42 days), all birds were fed a regular finisher diet. The results showed that the diet containing TM meal had no remarkable effect on the mortality rate and feed intake (FI) of broilers (P > 0.05). In the period of starter, the addition of 2.5% TM meal to broilers diet increased body weight gain (BWG) than the control group (P £ 0.05). Also, the use of 2.5% TM meal in the starter period showed a significant effect on reducing the feed conversion ratio (FCR) compared to the birds fed by the control diet (P £ 0.05). Besides, the height of the villus, the depth of the crypt, and the ratio of them were not altered among the different treatments (P > 0.05). Overall, it can be concluded that TM meal could improve growth performance in the starter period, and had no negative effects on broilers' performance and intestinal morphology in all the periods of the experiment.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.

The objective of the study was to determine the effects of probiotic bacteria Bacillus licheniformis and Bacillus subtilis on microbiological properties of feed mixtures and on the digestive tract content as applicable to production traits and carcass characteristics of fatteners. The experiment was performed on 83,838 fatteners from four successive (insertions) productions in two groups. From the seventy eighth day of age till marketing to the slaughter plant, the pigs were supplied with BioPlus YC probiotic (Chr. Hansen) in the amount of 400 g/t. The preparation contained a complex of probiotic bacteria Bacillus licheniformis DSM 5749, and Bacillus subtilis DSM 5750 spores in a 1:1 ratio. From the fourth insertion, after reaching a body weight of approximately 112 kg, 60 fatteners were selected from each group to measure carcass quality and half of them for meat quality evaluation. Moreover, microbiological analyses in feed and colon were performed. The study showed that BioPlus YC probiotics supplementation resulted in a significantly higher count of B. subtilis and B. licheniformis in the feed, a higher count of B. subtilis, B. licheniformis and LAB, as well as a lower count of Enterobacteriaceae, Enterococcus, Clostridium and Bacillus sp. in the mucosa and in the colorectal content of the test pigs. Our work has shown that supplementation with the BioPlus YC probiotic had a positive effect on the production traits of pigs mainly by reducing mortality (2.83%, p = 0.010), lowering feed conversion ratio—FCR (2.59 kg/kg, p = 0.013), better average daily gain—ADG (0.95 kg/day, p = 0.002) and shorter fattening period (77.25 days, p = 0.019) when compared to the control group (4.19%; 2.79 kg/kg; 0.89 kg/day; 92.8 days, respectively). The addition of the specific Bacillus bacteria did not influence carcass and meat characteristics of the test fatteners.

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 aim of this study was to investigate the effect of dietary garlic powder addition on productive performance and blood lipid status of broiler chicken. At the beginning of experiment, three treatments of 150 one day old broiler chickens of hybrid line Hubbard per treatment, on a total of 450 chickens were formed. Every treatment was divided in four groups which represents four replicates of the experiment. Control treatment (T1) was fed with mixtures without addition of garlic powder, while experimental treatments were fed with addition of 0.5% (T2) and 1.0% (T3) of dietary garlic powder, respectively. Experiment lasted 42 days. After the completion of experimental period the highest achieved body weight of chicken was at treatment T2 (2371.1g) which was followed by treatment T3 (2336.1 g) with statistically significant differences (p<0.05) compared to control treatment. For the entire experimental period, feed conversion ratio was lowest in treatment T2 (1.8 kg/kg) and the highest in control treatment T1 (2.1 kg/kg), without statistically significant (p>0.05) differences. Addition of garlic powder led to a statistically significant (p<0.05) increase in values of EBI in compare to a control treatment T1. The highest mortality rate (5.1 %) and the lowest EBI (220.4 %) were recorded in control treatment. Addition of garlic powder in the amount of 1.0% (T3) significantly (p<0.05) decreased LDL concentrations in blood serum. The lowest concentration of total cholesterol was recorded at treatment T2 (p<0.05). The highest concentration of HDL (44.8 and 39.6 mg/dl) was recorded in treatments T3 and T2. It could be concluded that the addition of garlic has positive influence on chicken production and blood lipid status, but the further investigation of their mode of action is still necessary.

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amaranth grain (AP) or dried above-ground biomass (AB). Control groups (C) received the diet containing animal proteins. The results obtained in the experimental groups of broiler chickens can be compared to the control group in all the production indicators under investigation. On day 42 of the experiment, live weight (g) of female broilers ranged from 2 205.1 &plusmn; 152.5 (AP) to 2 254.0 &plusmn; 136.5 (C), and that of male broilers from 2 375.1 &plusmn; 233.0 (AC) to 2 506.0 &plusmn; 286.0 (C). Feed conversion ranged from 1.80 kg in control group of male broiler chickens to 1.91 kg in experimental group of male broilers (AB). Percentage yield in female broiler chickens ranged from 70.8 &plusmn; 1.74 (AB) to 72.4 &plusmn;3.34(AC) or 72.4 &plusmn; 1.98 (C), and in male broilers from 72.8 &plusmn;3.55(AP) to 75.1 &plusmn;2.44(AB). Our results showed that amaranth can fully replace meat-and-bone meals in the diets for broiler chickens.

This study was done to determine the impacts Yucca schidigera supplementation to drinking water on the excretion of nitrogen, and subsequently the level of ammonia, intestinal bacterial count, hematological and biochemical parameters, and some performance parameters. A total of 270 one-day old Cobb 500 chicks were equally divided into three groups (90 chicks/group). The first control group (G1) was fed on the basal diets without any yucca supplementation. The 2nd and 3rd groups (G2 and G3) were fed on basal diets with Yucca Plus liquid®, at an 8 h/day supplementation rate of 0.5, and 1 mL/L to drinking water, respectively. The chicks that received yucca showed significant decreases in litter nitrogen content, when compared to controls. The chicks that received liquid yucca had reduced counts of total bacteria (TBC) (p < 0.05), Escherichia coli, and a non-significant increase in the number of lactic acid producing bacteria. They also showed increased activity of antioxidant enzymes, increased levels of immunoglobulins M and G, and decreased levels of lipid peroxidation biomarkers, without a harmful effect on liver and kidney function. The chicks that received yucca showed a better feed conversion ratio. In conclusion, the use of natural additives is necessary to decrease nitrogen losses, feed cost, and environmental pollution; without adverse impacts on animal performance. Liquid supplementation of saponins is valuable for the performance, gut health, and welfare of broiler chickens.
