| ABSTRACT The routine use of antimicrobials in animal production for the treatment of infections, disease prevention, or as growth promoters is a predisposing factor for the development and dissemination of antimicrobial resistance. In food industries, sanitizers are used for the control of microbial colonization, and their efficacy depends on contact time and on the dilution of the products used. The present study assessed the effect of 12 antimicrobials and four commercial sanitizers on 18 Salmonella spp. strains isolated from poultry processing plants. None of the evaluated antimicrobials was 100% effective against the tested Salmonella spp. strains; however, 94% of the isolates were susceptible to ciprofloxacin, 77% to amoxicillin + clavulanic acid and... |

| 1. This study examined whether a free range with roofed boxes with sand to structure the hen run had an effect on the numbers of hens going outside and on the distribution of the hens in the hen run. 2. On a poultry farm with 8 flocks of laying hens of roughly 500 birds per flock, each flock was observed with and without roofed boxes with sand. 3. There was no difference in the number of hens on free range with and without roofed boxes but there was an influence on the distribution. 4. In free range with structures there was a higher percentage of the hens outside in the furthest quarter where the structures were located. 5. We conclude that structures in the free range have an effect on the distribution of laying hens. |

| Background Over the past fifty years broiler production accounted for almost all of the meat chickens produced in the UK. As a result, only broiler hybrids were available for use by UK producers, and these were not thought to be suited for use in some extensive production systems. This meant that when consumer demand for extensively produced chicken meat increased in the late 1990s producers were unable to quickly identify and source the most suitable hybrids for UK conditions. Furthermore, systems of extensive production were still being developed, and little was known about design and management factors affecting range usage. Project OF0153 aimed to characterise breed suitability for extensive production (free-range, traditional free-range and... |

| The effect of the organic production system on broiler carcass and meat quality was assessed. Two hundred and fifty Ross male chickens were assigned to two different systems of production: conventional, housing in an indoor pen (0.12 m2/bird); organic, housing in an indoor pen (0.12 m2/bird) with access to a grass paddock (4 m2/bird). At 56 and 81 days of age twenty chickens per group were slaughtered to evaluate the carcass traits and the characteristics of breast and drumstick muscles (pectoralis major and peroneus longus). The organic chickens had carcasses with a higher breast and drumstick percentages and lower level of abdominal fat. The muscles had lower pHu and water holding capacity. Instead cooking loss, lightness values, shear values, Fe,... |

| Abstract This research was conducted to assess the compensatory gain in birds that have suffered severe food restriction and a reduced growth in its initial phase. A total of 144 birds were used in the Label Rouge lineage with average initial weight 239.90 ± 76.80 g, from 28 to 49 days. The experimental design used was a completely randomized design, where the birds were distributed in 18 boxes, containing 3 treatments and 6 replicates of 8 birds per cage. The treatments were as follows: birds with body weight of 150.73 ± 12.62 g, between weighing from 239.79 ± 13.14 g and heavy weight of 329.17 ± 24.89 g in different periods, from 28 to 35, 35 to 42 and 42 to 49 days of age, respectively. In relation to weight gain, the heavy birds, obtained better... |

| Production of entire male pigs could be a future strategy for organic pig production. However, production of entire males leads to increased risk of carcasses with elevated boar taint levels. It is hypothesized that skatole levels in pig meat are affected by soiling with manure and that organic housing facilities can increase the risk of pigs being heavily soiled. Therefore the overall aim of this study was to investigate if increased pig and pen soiling increases skatole concentration in entire male pigs. In 5 herds, 1174 organic entire male pigs were reared in four batches across two seasons, summer and winter. Measurements of pig and pen soiling, as well as fat skatole and androstenone concentration and human sensory tests of fat odour, were performed.... |

| To decrease dioxin uptake by the general population the European Union (EU) has set limits to the dioxin content of many foodstuffs including eggs. Eggs from free foraging chickens are known to have a higher dioxin content as compared to confined laying hens and it is the question whether these eggs can adhere to current EU regulations. The aim of the study was to investigate parameters that are involved in the contamination of eggs from chickens raised under “organic” conditions. Samples from 34 organic farms including soil and earth worm samples were collected between September and December of the year 2003. Dioxin levels were assayed by GC/MS. Various parameters were collected by on farm interviews. Egg dioxin content varied between 0.4 and 8.1 pg... |

| BACKGROUND: A sensory panel evaluated the sensory profile of eggs from hens from three experimental systems: (1) an indoor system × normal layer diet (InL), (2) a grass–clover forage system × normal layer diet (GrL), and (3) a grass–clover forage system × whole wheat and oyster shells (GrW). RESULTS: The taste of the albumen was significantly more ‘watery’ and the yolks a darker yellow/orange in the eggs from the GrL and GrW groups. The yolk was darkest from the GrW group. The yolks from the InL and GrW groups had a significantly more ‘fresh’, less ‘animal’, ‘cardboard’, and ‘intense’ aroma than the GrL group. The taste of the yolks from the InL and GrW groups was significantlymore ‘fresh’ and less ‘cardboard’-like compared to the GrL group. The yolks... |

| A total of 1,080 one-day-old broiler chicks were used, distributed into a completely randomized design in a 6 x 2 x 4 factorial scheme, with six replications of 30 birds each (15 males and 15 females). Chicks were classified into six breeds (Cobb 500 Slow, Cobb Fast, Ross 308, Ross 508, Hybro Plus and Avian 48), male or female and four slaughter ages (43, 45, 46 and 49 days). Ten birds from each experimental unit (5 males and 5 females) were slaughtered to evaluate carcass yield and commercial cuts. Cobb 500 Slow males showed the maximum potential for weight gain at 47 days old, while the other breeds, between 33 and 35 days old, regardless of sex. Carcass and breast fillet yield showed significant differences, independent of breed, sex and slaughter age,... |

| ABSTRACT The objective of the study was to investigate the influence of anise seed (Pimpinella anisum L.) powder supplemented to the drinking water on selected blood parameters of broilers. In total, 360 one-day-old Hubbard Classic chicks were randomly divided into four groups with three replicates of 30 birds each. Anise seed powder was added at 0, 500, 750, and 1000mg/L to the drinking water offered to the C (control), T1, T2, and T3 groups respectively. The supplement was supplied for 56 days. When broilers were 28 and 56 days old, blood samples were collected (30 birds per group) by brachial vein puncture to evaluate the cellular components of blood (RBC, WBC, Hgb, HCT, H/L). The following serum biochemical parameters were evaluated: CHOL, GLU, TP,... |

| Insect-based protein meals are in discussion as sustainable components in livestock and fish diets, with a potential to recycle wasted food materials and to replace partly feeds from arable land. Black Soldier Fly (BSF; Hermetia Illucens) is of particular interest in this context. Since insect production for animal feed appears as an additional trophic level in the food chain, it should either base on substrates, which are not directly edible for livestock and fish, or significantly improve feed efficiency or product quality to justify its application. Feed efficiency and product quality after replacing conventional protein sources by BSF meal were therefore tested in recent experiments with layers, broilers and trout. In a layer experiment, respectively... |

| In recent years, the United States has taken the lion’s share of the Chinese broiler meat import market, ranging from 53.0% to 84.9%. Under the threat of rising poultry imports from the United States Chinese producers asked for an investigation into chicken prices, accusing American poultry firms of dumping. The investigation led to antidumping duties on U.S. chicken imports as of February 13, 2010, ranging from 43.1% to 105.4%. This study is designed to evaluate U.S.-China poultry bilateral trade relations under the new tariff using an excess-supply-excess-demand model. The structural model is estimated using GMM with HAC (heteroskedasticity-autocorrelation) robust standard errors to obtain structural coefficients. The analysis focuses on chicken wings,... |

| Although several studies have estimated the costs of country-of-origin labeling (COOL), no previous study has documented how these costs will be distributed across the livestock sector or how producer and consumer welfare will be affected. This analysis presents an equilibrium displacement model of the farm, wholesale, and retail markets for beef, pork, and poultry that documents how producers and consumers will be affected by COOL. Findings reveal that as the costs of COOL are shifted from the producer to the processor and retailer, producers are made increasingly better off while consumers are made increasingly worse off. Further, an increase in aggregate consumer demand of 2% to 3% is likely sufficient to offset lost producer welfare due to COOL costs. |

| ABSTRACT This study was conducted to evaluate the effects of Curcuma longa on the growth performance, intestinal integrity, and antimicrobial activity of chicks colonized by Salmonella Typhimurium. The study included 672 one-day-old male chicks of the CobbTM lineage, which were divided into eight treatment groups with 14 birds per group and six repetitions, for a total of 48 experimental units per treatment. A randomized 4×2 factorial design scheme (C. longa levels × inoculation by Salmonella Typhimurium) was used. Chicks were orally inoculated with 1.2×104 cfu/mL of Salmonella Typhimurium in 0.5 mL of 0.85% buffered saline solution. Curcuma was added to the feed of chicks at 0, 1, 2, and 3% for 35 days. Data were analyzed by analysis of variance and... |

| The organic poultry production in Europe is increasing. The use of organic feed has been seen as one of the major constraint especially the protein sources, and efforts have been made to secure the future of this system. Access to outdoor area by organic chicken has been described as a means to partly compensate for their nutritional needs and the knowledge of feed items selected in the outdoor area can ease 100% transition to organic feed. An experiment was conducted to examine the effects of different feeding strategies on the foraging ability and nutrient digestibility of slow growing organic broilers with or without supplement. A total number of Seven hundred and twenty birds (RedBroja and Hubbard genotypes) have access to three different diets... |

| ABSTRACT The influence of different levels of expanded perlite on the performance and egg quality traits was studied in laying hens. Forty Lohmann Brown females at 30 weeks of age were randomly assigned to four groups consisting of five replicates with two hens in each. Four diet groups were supplemented with 0% (control group), 1%, 2%, and 3% perlite, respectively. Feed and water were provided ad libitum. There were no significant differences in final body weight, feed intake, egg yield, and egg weight. Feed conversion ratio and egg weight decreased with addition of 2% perlite. Dietary perlite supplementation has no significant effects on shape, yolk, and albumen index. Haugh unit was affected significantly by addition of 2% perlite. Fecal pH, dry matter,... |
