Abstract The study aimed to examine the meat quality of chickens from a dual-purpose cross and its parent lines. The trial was conducted in the experimental poultry farm of the Institute of Animal Science-Kostinbrod, Bulgaria. The dual-purpose chickens were obtained by crossing female layers (Line L) and dual-purpose cocks (BB, based on Bresse Gauloise). At the age of 9 weeks the male chickens from the parent lines and the dual-purpose cross were slaughtered. Six chickens of each genotype were subjected to breast and thigh meat quality analysis. The crossbred chickens tended to have lower pH in breast but the values of this parameter were higher in their thighs. The BB line showed the poorest water-holding capacity (WHC) in both breast and thigh meat cuts. This line and the crossbreed showed lighter meat compared to the L line. Except the ash content of the breast and thigh meat that was higher in the BB line, the proximate composition did not differ between the examined lines and their cross. The L and dual-purpose chickens tended to have higher intramuscular fat (IMF) but lower protein in thigh meat than the BB line. The correlation analysis revealed clear relationships between the meat quality traits and the proximate composition, however they differed for the breast and thigh meat.

Abstract The experiment studied the effects of different levels of Rumex patientia spp. leaf powder inclusion in laying hens’ diets on their physical parameters and yolk color intensity. The study was conducted on 168 Hy-line laying hens (30 weeks aged), assigned in 3 treatment groups (C, E1 and E2) and housed in an experimental hall equipped with Big Dutchman cages, placed on 3 tiers with digestibility cages (3 treatments × 28 replicates × 2 birds per cage). Feed and water were administrated ad-libitum. During the entire 5 weeks experimental period (one week of accommodation), performance parameters were recorded: average daily feed intake(g/day/hen), feed conversion rate (g feed/g egg), laying rate intensity (%) and average egg weight (g). Eggs yolk color is generated by carotenoids as a nutritional response, which depends on their amount, type, and ratio. One of the most important aspects in how consumers rate the quality of food is color. The experimental results demonstrated that an inclusion rate of 1.5% and 3% Rumex patientia species leaves powder improved the yolk color intensity without negative effects on production performances and egg quality parameters.

Abstract It was studied the main indicators of the functionality of reproductive system and their interrelation with the productivity indices of imported cows populations Holstein breed, belonging to 3 ecological types: the Dutch, the French and the German and our indigenous Moldovian type Black-Motley breed. The service period, was the shortest in cows of Moldovian type of Black-Motley breed with 38.1 days (P˂0.001), 30.2 days (P˂0.001) and by 14.5 days (P˂0.01.), compared to the Holstein German, Dutch and French ecological types, respectively. The difference of the duration of calvings interval between indigenous population and French ecological type was 18.2 days (p<0.01), compared to the German 46 days (P<0.001) and to the Dutch 36,5 days (P<0.001). There has been a difference of 9,9% in birth coefficient, between Moldovian type and Holstein German ecological type (p˂0.05). The best result of the coefficient of reproductive capacity has the indigenous type, opposite of German ecological type, which has the lowest performance (P˂0.001). Between the service period and the productivity indicators of the milk, regardless of the origin of the animal populations, were predominantly established, authentic positive correlative interrelationships, from weak to strong and statistically negative between productivity indices and the coefficient of the reproductive capacity of cows.

Abstract Food occupies a principal role in human life, having a major impact on health status and representing diverse characteristics that ensure valuable nutrient intake. Ensuring human nutrition has become one of the essential problems facing mankind, and quantity, quality and proper use of food have a major effect on the human body. Many raw materials and food products spoil easily, considerably shortening their shelf life. Extending the shelf-life of food is required to remove seasonal consumption, enlarge availability to the consumer and decrease losses in perishable food products, resorting to some procedures to preserve their properties. If natural antioxidants are used as alternatives for synthetic antioxidants, customer claims for food without damaging residual substances can be satisfied, and the poultry industry would benefit considerably. The principal objective of this review was to describe and under light the current situation regarding the role and importance of the use of antioxidant compounds obtained from natural sources in order to improve the nutritional qualities of eggs following their inclusion in the feed of laying hens. Data from bibliographic sources are analyzed and presented. The characteristics of a number of 9 plants with antioxidant potential are described with an emphasis on their characteristics, utilization, and possible effects on egg quality, performance, and health.

Abstract The post-weaning period is very stressful for piglets, leading to a transitory inflammation, alterations in the intestinal barrier, oxidative stress and a higher susceptibility to intestinal diseases with economic losses. The finding of new nutritional alternatives with anti-inflammatory, anti-bacterial, anti-oxidant properties is a challenge in post-weaning piglet’s nutrition. Of these strategies, those based on agro-industry wastes rich in bioactive compounds are promising, the increasing number of studies focusing on the use of these wastes as successful modulators of post-weaning – associated disturbances in piglets. This review describes the role of grape by-products in the modulation of inflammation, reinforcement of the intestinal barrier and their role as antioxidant factors. Also, their in-depth intracellular mechanisms of action related to their anti-inflammatory, antioxidant properties are described.

Abstract A six-week study was conducted to evaluate the effects of partial replacement of maize with Orange Fleshed Sweet Potato (OFSP) root meal on the haematological parameters and serum biochemistry of broiler chickens at finisher phase. One hundred and eight (108) day old broiler chicks were randomly allotted into 4 dietary treatments (T1, T2, T3 and T4) with 3 replicates each and 9 birds per replicate. The test ingredient, OFSP root meal was included in broiler finisher diets as replacement for maize at 0%, 6%, 12% and 18% in the dietary treatments respectively. The study revealed no effect on all the haematological parameters. The result of the serum biochemistry also showed no significant differences (P>0.05) on all the parameters measured with the exception of triglycerides, globulin and blood urea nitrogen with significant decrease in the triglycerides (mg/dl) and globulin (g/dl) content of T2(24.80 and 0.37), T3(47.01 and 1.07) and T4(48.50 and 1.41) respectively as compared with the control group (61.54 and 1.95 respectively). Therefore, inclusion of OFSP root meal up to 18% did not negatively affect the haematological parameters of the birds and also reduced the risk of metabolic diseases in the birds while improving the cardiovascular health of the birds.

Abstract The study aimed to assess the effect of dietary inulin (1% dietary inclusion) supplements on broiler chickens’ meat antioxidant compounds. The experiment was carried out under heat-stress conditions, on 60 Ross 308 broiler chickens. The study took place in an experimental hall with digestibility pens and controlled humidity, ventilation and light regime. Each treatment (2 groups, C and E) was replicated 6 times with 5 chicks per replicate pen with ad libitum feeding and free water access. At 42 days old, 6 birds from each group were slaughtered and breast and thigh meat samples were collected. The presence of inulin in broiler chickens’ diets had a beneficial effect by increasing the iron and zinc concentrations in thigh samples. Regarding liposoluble antioxidants, the presence of inulin in diets from tissue samples had an antagonistic effect: increased concentrations of xanthophylls were registered in thigh meat and an adverse effect was noticed in breast meat while an inverse effect was noticed for vitamin E. At the thigh meat level, the antioxidant capacity was significantly improved under inulin influence. In conclusion, the nutritional quality of broilers meat (thigh meat) was improved, for the group fed with inulin-supplemented diets.

Abstract The paper investigated the phytochemical content and antioxidant activity of poplar buds (Populus nigra L.), turmeric (Curcuma longa) and ginger (Zingiber officinale) extracts. Proximate composition, total polyphenols, ß-carotene, vitamin E, minerals and antioxidant capacity were tested for all selected plants. The proximate analysis of selected plants showed that poplar buds had a higher content of crude protein, fat and fiber than turmeric and ginger. The extract of poplar buds had a significantly higher content of total polyphenols (87.20 mg of gallic acid/g) and vitamin E (210.53 μg/g) than in the extract of turmeric and ginger. The polyphenol content was found to be in the order: poplar buds>turmeric> ginger. The beta carotene content was significantly higher in poplar buds (2.99 μg/g) than in turmeric (1.67 μg/g). Regarding mineral content, turmeric showed the highest content in iron and copper; ginger showed the highest content in manganese and poplar buds had the highest content in zinc. Moreover, poplar buds possessed the highest antioxidant capacity both on vitamin C and E calibration curve, evidencing the rich content in such antioxidants. Therefore, based on the valuable nutritional composition confirmed through this study, poplar buds, turmeric and ginger can be recommended as phytogenic feed additives for poultry nutrition.

Abstract This study was conducted to test the effect of two levels of rosehip meal used together with flaxseed meal on weekly production performances and blood parameters of laying hens. For that, we conducted a trial for 5 weeks on 120 laying hens (Tetra SL hybrid), aged 29 weeks. All three diets had 17.50% crude protein and 2780Kcal/kg metabolizable energy, but compared to the control diet (Con) the experimental diets contained 1.5% rosehip meal and 7% flaxseed meal (Diet1) or, 3% rosehip meal and 7% flaxseed meal (Diet2). The results revealed that only feed intake was significantly (P=0.0001) affected, being lower in experimental groups. Among the haematological parameters, the heterophile were significantly higher (P=0.0377) in both Diet1 and Diet2 groups versus the Con group. From the biochemical parameters analysed, in the lipid profile, glucose and triglycerides were significantly lower in the Diet2 group compared with both the Diet1 and Con groups. Total bilirubin was significantly higher (P=0.0020) in the Diet1 group compared to the Con and Diet2 groups, while the lactate dehydrogenase was lower (P=0.0414) in the samples of the Diet2 group. Overall, the studied ingredients had a slight influence on production performances and improved some blood parameters, especially the lipid profile of the Diet2 group.

All three diets had 17.50% crude protein and 2780Kcal/kg metabolizable energy, but compared to the control diet (Con) the experimental diets contained 1.5% rosehip meal and 7% flaxseed meal (Diet1) or, 3% rosehip meal and 7% flaxseed meal (Diet2). The results revealed that only feed intake was significantly (P=0.0001) affected, being lower in experimental groups. Among the haematological parameters, the heterophile were significantly higher (P=0.0377) in both Diet1 and Diet2 groups versus the Con group. From the biochemical parameters analysed, in the lipid profile, glucose and triglycerides were significantly lower in the Diet2 group compared with both the Diet1 and Con groups. Total bilirubin was significantly higher (P=0.0020) in the Diet1 group compared to the Con and Diet2 groups, while the lactate dehydrogenase was lower (P=0.0414) in the samples of the Diet2 group. Overall, the studied ingredients had a slight influence on production performances and improved some blood parameters, especially the lipid profile of the Diet2 group.","PeriodicalId":170796,"journal":{"name":"Archiva Zootechnica","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132623636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Enterococcus faecium (NCIMB 11181) was evaluated for survivability, safety, and capacity as probiotics utilization. Gram-positive, catalase-negative test, antibiotics susceptibility, hemolysis activity, pH and bile salts resistance were screened using selective microbiological media. The strain was phenotypically assessed for its principal probiotic properties. The capacity of fermentation based on biochemical tests was evaluated by API 20STREP and interpretation by apiwebTM Biomerieux (France) software (99.2% very good identification). After incubation at 37°C for 22-24 h in aerobic conditions, E. faecium involves 13.96 Log10 with an optical density (OD 600 nm) from 0.2 in the first 2 hours of growth to 0.9 value. The safety assessment on TSA agar showed that the strain revealed α-hemolysis. Resistance to 16 clinically relevant antibiotics, presented for our strain a range from intermediate (81.25%) to susceptible (6.25%), followed by resistance to erythromycin and colistin sulfate. The strain exhibited tolerance to acidic conditions and simulated gastric environment. Therefore, E. faecium NCIMB 11181 can be considered a safe strain without creating a risk to animal health status. It may be used as a probiotic preparation product for application in animal nutrition.
