The aim of the study was to determine the effect of different levels of DL-methionine in feed for broiler chickens on the quality of vacuum-packed breast muscles stored under refrigeration. The material for the study was 72 breast muscles from 35-day-old broiler chickens fed diets with varying content of DL-methionine. The control group received a basal diet without additional DL-methionine, while the experimental groups received compound feeds supplemented with 0.08% or 0.24% DL-methionine. At 35 days of age, 24 birds from each group were randomly selected and experimentally slaughtered. After the carcasses were dissected, 8 right breast muscles were selected from each feeding group and analysed immediately after cooling. The remaining muscles were vacuum-packed and after 7 and 14 days of storage physicochemical and sensory analyses were performed to assess the influence of storage time on changes in their quality. The methionine level was not found to affect the sensory properties of the breast muscles, but the meat of birds receiving a higher level of this amino acid had better shear force and water-holding capacity in comparison to the control group. After just 7 days, the results of the analyses of vacuum-packed refrigerated muscles showed a negative effect of storage time on the capacity of the muscle tissue to bind water, as well as changes in the proportion of red colour in the muscles. However, it is worth noting that the sensory quality of the muscles deteriorated only after 14 days of storage.

This study was conducted in the Poultry Field of the College of Agriculture, Basrah University for the period from 20/9/2019 to 24/10/2019 to investigate the effect of adding different levels of Portulaca oleracea L. seeds and leaves powder on some physiological characteristics of broilers. A total 216 one day old unsexed Ross-308 broiler chicks were used in this study. The chicks were randomly distributed into six treatments replicated three times (12 chicks each replicate). The experiment was designed as a completely randomized design (CRD). The first treatment was control (basal diet), P. oleracea seed powder was added as 5 & 10 g.kg-1 for the 2nd and 3rd treatments. Leaves powder was added as 5 and 10 g.kg-1 to the basal diet in treatment 4th and 5th. In the 6th treatment 5 gm of seed and 5 gm of leaves powder was added to the basal diet. The results showed that there was a significant (P <0.05) decrease in serum glucose, cholesterol and triglyceride concentrations in all additive treatments compared to control. There was also a significant decrease (P <0.05) in Escherichia coli bacteria count, as well as a significant improvement (P <0.05) in the number of Lactobacilli bacteria in all addition treatments compared to the control group. The addition of P. oleracea seeds and leaves powder had no significant effect on some haematological indices and on the total protein concentration in the serum. The study confirms the importance of adding powder of seeds or leaves in the broiler diet because it has a positive role in improving some of the physiological and microbial blood characteristics of the broiler.

AbstractIt was postulated that administration of a probiotic to chickens can stimulate their antioxidant status while at the same time inhibiting oxidation processes. The objective of the study was to determine whether and how different levels and durations of application of a probiotic preparation containing live cultures of Enterococcus faecium and enriched with cholecalciferol and ascorbic acid influences indicators of lipid status and the redox reaction in the blood of broiler chickens. Four hundred day-old Ross 308 chickens were raised until their 42nd day of age. The animals were assigned to five experimental groups of 80 broilers each: a control group that did not receive the probiotic, T1 groups, which received the probiotic at 0.25 (E-0.25) or 0.1 g/l (E-0.1) throughout the rearing period, and T2 groups, which received the probiotic at the same levels, but during days 1–7, 15–21 and 29–35 of life. The probiotic preparation reduced the level of peroxides (LOH), malondialdehyde (MDA), cholesterol (TC), low density (LDL) cholesterol, and non-esterified fatty acids (NEFA), and the activity of catalase (CAT), gamma-glutamyltransferase (GGT), acid phosphatase (AC), alkaline phosphatase (ALP) and 3-hydroxybutyrate dehydrogenase (HBDH), while ferric reducing ability of plasma (FRAP) and glutathione (GSH + GSSG) levels were increased in the blood plasma of the chickens. The results obtained indicate that administration of this probiotic to chickens, especially in the amount of 0.25 g/l for the entire rearing period, stimulates synthesis of low-molecular-weight antioxidants responsible for maintaining redox homeostasis, without exerting a negative effect on liver metabolism in chickens.

This study was conducted to examine the effect of two humic substances (HS) supplemented in broilers’ diet on the breast meat quality of broiler chickens. In this experiment, 120 pieces of one-day-old COBB500 broiler chickens were used. Broilers were divided into three groups, each containing 40 birds with three replications (13, 13, and 14 per one pen). Fattening lasted 38 days. The first experimental diet was supplemented with 0.7% of HS (HS0.7) and the second was enriched with 0.7% of acidified HS (HSA0.7). The control group of broilers (C) was fed a basal diet without the addition of any supplements. HS0.7 samples had the highest total protein content and the lowest content of fat (p < 0.01). The effects of broiler diet and storage had a significant impact on the pH of breast samples, p < 0.001 and p < 0.05, respectively. Supplementation of HS in broiler diet positively affected the lipid oxidation of breast meat samples, as indicated by the lower malondialdehyde content (p < 0.05). HSA0.7 samples had significantly better juiciness after the storage period (p < 0.001). The quality of meat produced with supplementation of HS in broilers’ feed can be considered as valuable in human nutrition due to improved protein and fat content with decreased lipid oxidation.

In this paper the effect of extruded rapeseed meal on the performance and sensory quality of the breast meat of broilers was investigated. The experiments were performed with hybrid line ROSS 308. The control group was fed soybean meal, and two levels of extruded rapeseed meal were added in experimental groups, 4% and 8% during a period of 42 days. Final body masses of chicken in the experimental groups were lower for 1.79% and 3.05% than the control group. Conversion of feed was satisfactory in all groups, and the best in the control group. Including extruded rapeseed meal in the meal did not show negative effect on the sensory quality, the smell and the colour, of fresh breast meat. Sensory quality (smell, taste and sensitivity) of heat-treated breast meat of the chickens in the control and experimental groups was marked as "very good", or optimal.

ABSTRACT Objetive. In the present study a completely randomized 3×3 factorial design was used to analyze the effects of different levels of L-Carnitine, lysine(Lys) and methionine (Met) on the blood concentrations of energy, protein and lipid metabolites of male broiler chickens. Materials and methods. A total of 270 newly hatched male broiler chickens (Ross 308) were randomly assigned to 9 groups (ten broilers per replicate and three replicates per treatment). The control group was fed a basal diet, whereas the treatment groups were fed basal diets supplemented with L-Carnitine (0 mg/kg, 75 mg/kg and 150 mg/kg) and lysine-methionine (0, 15 and 30%) for 42 days. On day 42, one bird was randomly chosen per replication, a blood sample was taken and the blood concentrations of glucose (GLU), uric acid (UAc), triglyceride (TG), VLDL, HDL, LDL, total protein (TP), albumin (Alb) and total cholesterol (TC) were analyzed. Results. Dietary L-carnitine supplementation had a significant effect (p<0.05) on uric acid (UAc), HDL, LDL, and total cholesterol (TC). The birds feed L-carnitine plus Lys and Met presented the highest plasmatic UAc level and the lowest plasmatic TC and LDL level. Moreover, L-carnitine significantly reduced total cholesterol (TC) when compared with both the control group and the birds feed Lys and Met without L-carnitine. Conclusions. A diet with 150 mg/kg L-carnitine plus 15% Lys and Met seems to be enough to sustain low plasmatic TC, LDL and HDL concentrations on male broiler. RESUMEN Objetivo. Se realizó un estudio para determinar el efecto de la suplementación deL-carnitina, lisina (Lys) y metionina (Met) sobre los metabolitos sanguíneos de pollos de engorde. Materiales y métodos. Se utilizaran 270 pollos de la línea Ross 308 de un día de edad y se dividieron en 9 tratamientos en un diseño al azar con arreglo factorial 3x3: tres niveles de L-carnitina (0 mg/kg, 75 mg/kg y 150 mg/kg) y tres de lisina-metionina (0, 15 y 30%) durante 42 días. Cada tratamiento constó de 3 repeticiones con 10 pollos por repetición. El día 42 de edad, se tomaron muestras de sangre de tres aves por tratamiento para cuantificar niveles séricos de glucosa (GLU), ácido úrico (UAc), triglicéridos (TG), VLDL, HDL, LDL, proteínas totales (PT), albúmina (Alb) y colesterol total (TC). Resultados. La suplementación de L-carnitina en la dieta tuvo un efecto significativo (p<0.05) en los niveles de ácido úrico en suero (UAC), HDL, LDL y colesterol total (CT). Las aves alimentadas con L-carnitina más Lys y Met mostraron niveles séricos más altos de UAc y menor TCy LDL. Por otra parte, la L-carnitina redujó significativamente el colesterol total (CT), cuando se comparó con el grupo control y con los pollos alimentados con Lys y Met, sin L-carnitina. Conclusiones. Una dieta con 150 mg/kg de L-carnitina y 15% Lys y Met parece ser suficiente para mantener bajas concentraciones plasmáticas de TC, LDL y HDL en pollos de engorde.

Abstract The objective of this work was to evaluate the effect of the use of hybrid phytase, alone or combined with carbohydrases, in poultry diets with nutritional reductions of calcium, available phosphorus, and metabolizable energy on the nutrient digestibility and bone quality of broiler chickens. A total of 1,875 broilers were distributed in five treatments in a completely randomized design, with 15 replicates of 25 chickens each. The treatments consisted of a positive control feed (T1) and of four negative controls (T2 to T5): T1, basal diet (BD) with corn and soybean; T2 and T3, BDs with reductions of 70 and 100 kcal kg-1 metabolizable energy, respectively, and both with reductions of 0.16% Ca and 0.15% available P; and T4 and T5, BDs with the same nutritional reductions, but supplemented with enzymes, i.e., T4 = T2 + 500 phytase units (FTU) per kilogram and T5 = T3 + 500 FTU kg-1 + 560 xylanase units (TXU) per kilogram + 250 glucanase units (TGU) per kilogram. The use of 500 FTU kg-1 hybrid phytase in pelleted corn-soybean meal diets allows a good digestive performance by broilers and replaces the nitrogen-corrected apparent metabolizable energy at 70 kcal kg-1, as well as 0.16% Ca and 0.15% available P.

The effect of edible coating of gelatin (1, 2 and 3%) containing aqueous extract of rosemary (1% and 2%) on physiochemical (pH, total volatile nitrogen, peroxide values and water holding capacity) and microbiological (psychrotrophic) properties of duck fillet were evaluated. The pH of coated samples were significantly (plessthan0.05) lower than that of untreated sample. TVN (total volatile nitrogen) value increased with storage period in all the samples but coatings significantly decreased production of TVN compared to the control. Also the coatings decreased lipid oxidation of the meat as rosemary postponed primary oxidation of fillet, while this parameter in control group was sharply increased by time. WHC (water holding capacity) increased significantly (plessthan0.05) with storage period and level coatings. Coating had a significant reducing effect on growth of psychrotrophic bacteria during 9 days at 4°C. In conclusion, gelatin edible coating enriched with rosemary could retard chemical and microbial reactions related to spoilage of meat during refrigerated storage.

Marine algae polysaccharides have been shown to regulate various biological activities, such as immune modulation, antioxidant, antidiabetic, and hypolipidemic. However, litter is known about the interaction of these polysaccharides with the gut microbiota. This study aimed to evaluate the effects of marine algae Enteromorpha (Ulva) prolifera polysaccharide (EP) supplementation on growth performance, immune response, and caecal microbiota of broiler chickens. A total of 200 1-day-old Ross-308 broiler chickens were randomly divided into two treatment groups with ten replications of ten chickens in each replication. The dietary treatments consisted of the control group (fed basal diet), and EP group (received diet supplemented with 400 mg EP/kg diet). Results showed that chickens fed EP exhibited significantly higher (P &lt; 0.05) body weight and average daily gain than the chicken-fed basal diet. In addition, significantly longer villus height, shorter crypt depth, and higher villus height to crypt depth ratio were observed in the jejunal and ileal tissues of chickens fed EP. EP supplementation upregulated the mRNA expression of NF-κB, TLR4, MyD88, IL-2, IFN-α, and IL-1β in the ileal and jejunal tissues (P &lt; 0.05). Besides, we observed significantly higher (P &lt; 0.05) short-chain volatile fatty acids (SCFAs) levels in the caecal contents of the EP group than in the control group. Furthermore, 16S-rRNA analysis revealed that EP supplementation altered gut microbiota and caused an abundance shift at the phylum and genus level in broiler chicken. Interestingly, we observed an association between microbiota and SCFAs production. Overall, this study demonstrated that supplementation of diet with EP promotes growth performance, improves intestinal immune response and integrity, and modulates the caecal microbiota of broiler chickens. This study highlighted the application of marine algae polysaccharides as an antibiotic alternative for chickens. Furthermore, it provides insight to develop marine algae polysaccharide-based functional food and therapeutic agent.

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.

Enzyme supplementation in diets based on corn and soybean meal can improve the productive performance of broilers. Thus, we aimed to evaluate the effect of the inclusion of different levels of an enzyme complex consisting of phytase, protease, xylanase, ?-glucanase, cellulase, amylase, and pectinase, for diets based on corn and soybean meal, on the parameters of carcass yield and meat quality of broilers. Six hundred broiler chicks were used, and the animals were females with one day of age, from the Cobb 500 strain, and distributed in a completely randomized design, with five levels of inclusion of the enzyme complex (0, 100, 200, 300 and 400), and six repetitions, with twenty animals each. The carcass yield and meat quality were evaluated at 35 and 42 days of age. We evaluated the characteristics of weight loss by cooking (WLC), shear force (SF), water holding capacity (WHC), pH, lightness (L*) and color (a* and b*). The parameters of performance, carcass yield and carcass parts, and meat quality were not affected by the enzyme supplementation of diets fed to broiler chickens (P >0.05), except for the performance characteristics of the breast and the wings at 42 days of age (P < 0.05).
