Over the past fifty years, most poultry in the UK have been managed in specialist indoor systems and excluded as a significant enterprise from most other farm types. This meant that there was little information on how to integrate poultry into land-based systems such as organic production. This Defra project OF0163 aimed to assess methods of integrating organic poultry into crop rotations, taking into account the need to meet the birds’ nutritional and physiological requirements for health and performance, the recycling of nutrients between soil, plants and birds and practical limitations of the system. Objectives 1. To review the scientific literature available on home grown protein sources so as to identify their maximum inclusion rates in organic... |

Em decorrência do contínuo crescimento da avicultura no Brasil, tanto de corte quanto de postura, ocorre concomitantemente um aumento de alojamento de matrizes e, portanto, dos resíduos formados pela incubação de ovos férteis. Em contrapartida no Estado de São Paulo criou-se, recentemente, a Lei no 12.300, de 16 de março de 2006, obrigando os incubatórios a dar um destino adequado aos seus resíduos. Devido ao custo de manejo dos resíduos, tem-se a oportunidade de se estudar novas alternativas, que possam eventualmente agregar valor ao produto, possibilitando sua comercialização. Objetivou-se neste estudo analisar quais os destinos dados aos resíduos de incubatórios no Estado de São Paulo. Um grupo de cinco empresas representativas foi entrevistado.... |

Poultry are considered to be the main reservoir of Campylobacter spp. bacteria, an important pathogen for humans. Many studies have reported a rapid selection of fluoroquinolone-resistant strains following the widespread use of these antimicrobials in poultry production and human medicine. The main mechanism of fluoroquinolone resistance in Campylobacter is a mutation in the Quinolone Resistance Determinant Region (QRDR) in the gyrA gene, which codes for the subunit of the enzyme DNA gyrase, the target for fluoroquinolone. The aim of this study was to investigate the mutation in QRDR in the gyrA gene of Campylobacter strains previously isolated from broiler carcasses and feces of laying hens. Thirty-eight strains of C. jejuni and 19 C. coli strains (n=57),... |

ABSTRACT Environmental temperatures currently considered within comfort zone for broiler rearing may be misleading or even obsolete from actual values. Some factors such as animal genetics, nutrition and poultry management, mainly acclimatization to tropical and subtropical conditions, influence in determining the comfort zone for birds. This study aimed to evaluate the effects of five different thermal environments on animal welfare and rearing performance of broiler chickens, setting an ideal temperature range (comfort zone) for each of the first three weeks of poultry breeding. The chicks (375) were randomly placed into five climatic chambers set to distinct thermal conditions, being: one as recommended by the literature, another as stated by Cassuce... |

The objective of this study was to estimate the true digestibility coefficients of amino acids and digestible amino acid values of some poultry feedstuffs. The feedstuffs were: babassu meal, sunflower meal, corn gluten meal, babassu starchy meal, meat and bone meal, common beans, pearl millet and residues of cookies, pasta and bread. The precise feeding method of Sibbald was used with adult cecectomized Leghorn roosters distributed in a completely randomized design, consisting of ten treatments and six replications with a rooster in each. The treatments were represented by the feedstuffs evaluated. The roosters were kept in a period of fasting for 36 hours and then fed 30 grams of feed. Samples were collected during 56 hours. Simultaneously, six roosters... |

Brazilian poultry production is very efficient and demands maximum broiler performance. Therefore, digestive system pathologies have a relevant role. Considering it is difficult to obtain consistent information on intestinal morphometric analysis, this study aimed at establishing essential and clear criteria for the collection of intestinal segments for morphometric analysis. Fifteen 13-d-old broilers were sacrificed and three intestinal segments were collected per bird. Two 3-cm long sections were obtained from each of the intestinal segments. Samples were collected open or closed. The closed samples were transversely, hemicylindrically, or longitudinally sectioned. Samples were processed and stained with hematoxylin and eosin. The number of microscopic... |

Adhesion proteins from Mycoplasma gallisepticum (MG) encoded by cytadhesion genes mgc1 and mgc2 were cloned into plasmid vectors and transformed into E. coli. Seventeen groups of specific-pathogen free (SPF), birds at four weeks of age were used to inoculate these two proteins (MGC1 and MGC2) mixed into an oil emulsion creating a novel MG vaccine. Six different protein concentrations (50, 100, 200, 400, 800, and 1000µg/bird) were tested with two equal concentration doses at four and seven weeks of age. In addition, many control groups were needed such as bacterin, membrane, no vaccine or challenge, oil emulsion alone, and no vaccine but challenged. Three weeks following the second vaccination, 50% of the birds in each treatment group were challenged with... |

This report was presented at the UK Organic Research 2002 Conference. Because conventional production of chickens has gone further than any other animal production system towards complete control of the animal’s brief lives, development of effective silvo-poultry systems seems particularly necessary for these essentially woodland birds. The objective is to develop a production system that closely matches the physiological and behavioural needs of the animals being reared. For the example of chickens, this means trying to mimic a woodland/forest-clearing environment. By providing a wide range of trees, shrubs and herbs, it should be possible to provide shelter, nutrition and medicinal benefits for the birds. At the same time, the system needs to fulfil... |

Artgemäße Legehennenhaltungssysteme zeichnen sich durch verschiedene Funktionbereiche, wie erhöhte Standorte und Sitzstangen, ausreichend Scharraum, Staubbademöglichkeit, Nester, Außenklimabereich und Auslauf aus. Die Ställe sind mit Tageslicht ausgeleuchtet und die Tiere werden nicht schnabelkupiert. Konventionell in Dunkelställen, ohne erhöhte Sitzstangen aufgezogene Tiere zeigen Verhaltensänderungen und häufig Federpicken, das bis hin zum Kannibalismus führen kann. Eine Verringerung der Schäden wird durch eine Lichtreduktion des Kunstlichtes bis auf 10- 15 LUX erreicht. Junghennen aus konventioneller Aufzucht sind aus diesen Gründen nicht für die Einstallung in artgemäße Legehennenhaltungssysteme mit Tageslicht geeignet. Ziel dieser Untersuchung... |

This research was aimed to evaluate the effect of dietary supplementation of either powdered or encapsulated probiotic on relative carcass, giblet weight and intestinal morphometry of local duck. One hundred twenty male day old duck (DOD) were distributed to 6 different dietary groups, included 2 probiotic forms of either powdered (T1) or encapsulated (T2) and 3 levels: 0% (L0), 0.2% (L1), 0.4% (L2). They were reared using pen cages for 42 days (6 weeks). Observed variables were relative carcass, giblet weight (gizzard, heart, liver) and intestinal morphometry (villus height, villus width, crypt depth). Data were analyzed by Nested of Completely Randomized Design ANOVA and if there was significant effect followed by Duncan’s Multiple Range Test (DMRT). The... |

Surface area (SA) of poultry is an important parameter for heat and mass transfer calculations. Optical approaches, such as the moiré technique (MT), are non-destructive, result in accuracy and speed gains, and preserve the object integrity. The objective of this research was to develop and validate a new protocol for estimating the surface area (SA) of broiler chickens based on the MT. Sixty-six Ross breed broiler chickens (twenty-seven male, thirty-nine female, ages spanning all growth phases) were used in this study. The dimensions (length, width and height) and body mass of randomly selected broiler chickens were evaluated in the laboratory. Chickens were illuminated by a light source, and grids were projected onto the chickens to allow their shape to... |

Sedan 1 augusti 2000 är det inte längre tillåtet att tillsätta syntetiskt metionin till ekologiskt värphönsfoder, vilket komplicerar sammansättningen av ett fullvärdigt foder. För att metioninrestriktionen inte ska påverka djurens välbefinnande negativt så finns det, som vi ser det, två lösningar. Antingen kan mängden utfodrad metionin ökas genom att öka proteininnehållet i fodret, vilket leder till en icke önskvärd överutfodring av protein, eller så kan man med avelsarbete genetiskt anpassa hönorna till ett foder med lägre metionininnehåll. Del 1: Ekologisk äggproduktion är vad beträffar djurmaterial, foder, djurhälsa och effektivitet långt ifrån fulländad. Ett djurmaterial vid SLU har under ca 25 generationer selekterats för goda hälso-... |

The aim of this experiment conducted at four sites in Switzerland was to investigate the transmission and infectivity of the two main helminth parasite species of poultry (Ascaridia galli and Heterakis gallinarum) in outdoor runs with two different stocking rates. Additionally, the influence of a simplemanagement practice (mowing of run) on helminth transmission was studied. Three run types were created on each site: runs C served as control (stocking rate 10 m2/hen, no management), runs B corresponded to runs C but were managed (10 m2/hen, management). In runs A stocking rates were doubled compared to control runs (5 m2/hen, no management). During two subsequent layer flocks, a set of parasitological parameters (faecal egg counts (FECs), prevalence, worm... |

Sheepdrove Organic Farm wanted to know whether the source of day old chicks and brooding and production period would have an impact on their enterprise. Sheepdrove Organic Farm wanted to know whether the source of day old chicks and brooding and production period would have an impact on their enterprise. An experiment was undertaken using two different sources of day old chicks and on two sites. 1000 day old chicks from Maurice Millard were exchanged with 1000 organic chicks from Devon Foods. These chicks were then put through the Sheepdrove (SOF) and Devon Foods Bradbury Barton (BB) organic production systems and weighed every week until depletion. The two systems were not identical and there were slight variations between the SOF and BB systems. BB had... |

NORSØK fikk i oppdrag fra Regelverksutvalget for økologisk landbruk å undersøke om det er forhold i økologiske driftssystemer for slaktekyllingproduksjon som kan bidra til å redusere risikoen for sykdom med påfølgende antibiotikabehandling, og samtidig imøtekomme krav om økt andel egenprodusert fôr og utfasing av konvensjonelle proteinfôrmidler. I Norge er det liten økologisk fjørfeproduksjon, men fjørfe er husdyret som har størst forskjell i dyrevelferd når man sammenligner økologisk og konvensjonell produksjon. NORSØK har vurdert velferd hos produsenter med økologisk slaktekylling, intervjuet produsenter, sendt ut spørreskjema til andre aktører og gjennomført litteraturstudie. Saktevoksende raser, miljøberikelser, lav dyretetthet og tilgang til et... |
