Provedor de dados: 32
Autores: Chan Díaz, David Jesús.
Se realizaron dos experimentos para evaluar dietas suplementadas con arginina (ARG), vitamina E (VE) y manano-oligosacáridos (MOS) en la inmunidad de pollos. En el primero, 700 pollos (1 día de edad), fueron divididos en 28 grupos y recibieron una de cuatro dietas: T1 = 1.31 % ARG y 10 mg de VE/kg;  T2 = T1 + 0.3% de ARG; T3 = T1 + 70 mg de VE y T4 = T1 + 0.3 % ARG + 70 mg de VE. A los 12 días de edad, recibieron las vacunas contra Newcastle (EN), bronquitis, influenza (IA) y viruela; las variables evaluadas fueron la reacción postvacunal y la respuesta inmune. En el segundo experimento, 200 pollos (1 día de edad) fueron divididos en ocho tratamientos con arreglo factorial 2 x 4, los factores fueron: La vacuna contra coccidiosis (aplicada o no), y cuatro...

Aceite de orégano (Lippia graveolens) como antioxidante en la peroxidación lipídica de la carne de pollos de engorda
Provedor de dados: 32
Autores: Zacatula Mier, Heriberto.
En la alimentación humana, la carne es una parte importante de la dieta, representa  aproximadamente 11% del total del consumo de alimentos. La carne de pollo, por su alto valor  nutrimental, bajo costo y alta disponibilidad, es uno de los productos de origen animal de mayor  consumo y aceptación. Lo que ha resultado que a nivel mundial, en los últimos 30 años su  producción se haya cuadruplicado, mientras que la de otras especies, como la de cerdo, sólo ha  duplicado su volumen (FAO, 2007).   En las últimas décadas una parte importante de la investigación en el ámbito de la nutrición  animal se ha dirigido a mejorar el valor nutritivo de los alimentos de origen animal, para ofrecer al  consumidor un producto de acuerdo a su demanda y necesidades, con...

Provedor de dados: 70
Autores: Ponciano,Patrícia F.; Yanagi Junior,Tadayuki; Ferraz,Gabriel A. E S.; Scalon,João D.; Schiassi,Leonardo.
The air dry-bulb temperature (t db),as well as the black globe humidity index (BGHI), exert great influence on the development of broiler chickens during their heating phase. Therefore, the aim of this study was to analyze the structure and the magnitude of the t db and BGHI spatial variability, using geostatistics tools such as semivariogram analysis and also producing kriging maps. The experiment was conducted in the west mesoregion of the states of Minas Gerais in 2010, in a commercial broiler house with heating system consisting of two furnaces that heat the air indirectly, in the firsts 14 days of the birds' life. The data were registered at intervals of five minutes in the period from 8 a.m. to 10 a.m. The variables were evaluated by variograms...

Polymorphism analysis of the hsp70 stress gene in Broiler chickens (Gallus gallus) of different breeds
Provedor de dados: 74
Autores: Mazzi,Carmen Maria; Ferro,Jesus Aparecido; Ferro,Maria Inês Tiraboschi; Savino,Vicente José Maria; Coelho,Antonio Augusto Domingos; Macari,Marcos.
The promoter region and the beginning of the coding region of the hsp70 stress gene were analysed in broiler chickens of a commercial breed (Hubbard-Pettersen), a breed selected for weight gain (PP1) and a non-selected breed (naked-neck Label Rouge). The naked neck gene (Naked neck, Na), which reduces feathering in birds and is thus related to heat resistance, was present in both PP1 and Label Rouge breeds. Genomic DNA was restricted with PstI and Southern blotting analysis of the samples revealed the absence of polymorphic sites for that enzyme in the promoter region and beginning of the coding region of the hsp70 gene of studied birds. PCR-SSCP analysis of these regions, however, indicated the presence of polymorphisms in the beginning of the coding...

Public Attitudes to the Welfare of Broiler Chickens
Provedor de dados: 31
Autores: Hall,   Clare; Sandilands,   Victoria.
This paper reports results from two workshops held in York, England that investigated public attitudes towards the welfare of broiler chickens. At the outset the majority of participants admitted that they knew little about how broiler chickens are reared and were shocked at some of the facts presented to them. Cognitive mapping and aspects of Q methodology were used to reveal the range of variables that participants believed affected chicken welfare, the causal relationships between those variables, and what variables were considered most and least important. While some participants focused on the importance of meeting basic needs such as access to food, water, light and ventilation, others highlighted the role of welfare regulations and public opinion....

AN APPROACH TO A MICROBIOLOGICAL RISK ASSESSMENT IN THE POULTRY SECTOR IN TRINIDAD
Provedor de dados: 31
Autores: Dookeran,   Mark M.; Baccus-Taylor,   Gail S.H.; Akingbala,   John A.
International studies and epidemiological data have revealed a strong association between salmonellosis and chicken meat.  This association provides serious challenges for food safety and international trade.  Microbiological Risk Assessment is a food safety tool that is used to determine the incidence of food borne illnesses.  The procedure identifies a microbiological hazard in the entire food continuum (from farm to fork), and estimates the adverse effects to human health, of ingesting the microbial hazard. The Assessment integrates four steps, hazard identification, hazard characterisation, exposure assessment and risk characterisation, to produce a practical estimate of risk. In each step, knowledge of the prevalence and concentration of the pathogen,...

Autores: Oliveira,JE; Albino,LFT; Rostagno,HS; Páez,LE; Carvalho,DCO.
Three experiments were conducted to determine the nutritional requirements of potassium (K) for male Ross broiler chickens, from 8 to 21, 22 to 42 and 43 to 53 days of age. The following parameters were evaluated: body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR). In each experiment, a completely randomized experimental design was used, with six treatments (K levels), and six, eight and eight numbers of replicates, and eight, five and four birds per pen, respectively. The experimental diets were basal diets deficient in K but supplemented with K carbonate to result in levels of 0.30, 0.44, 0.58, 0.72, 0.86 and 1.00% K. Estimated requirements for BWG were 0.628, 0.714 and 0.798% K, for the periods 8-21, 22-42 and 43-53 d, respectively.

In the present study we have investigated the effects of heat acclimation on brain and hepatic Hsp70 protein levels and body temperature of broiler chickens in response to gradual heat stress. Two groups of broilers were raised up to 47 days of age under distinct temperature conditions: thermoneutral (TN, according to bird age) or hot environmental (HS, 31-33°C). At 46 days of age, the birds reared at high ambient temperature were transferred to thermoneutrality conditions. After 18 h, these birds and the birds reared at thermoneutral temperature were submitted to gradual heat stress in a climatic chamber so that environment temperature was increased from 28 to 40ºC at a rate of 2ºC/h. Colonic temperature was measured using a thermometer sensor probe at...

Autores: Rosa,PS; Faria Filho,DE; Dahlke,F; Vieira,BS; Macari,M; Furlan,RL.
In order to evaluate the effect of energy intake and broiler genotype on performance, carcass yield, and fat deposition, 600 one-day-old male chicks from two different genetic groups (AgRoss 308 - commercial line and PCLC - Embrapa non-improved line) were fed diets with different metabolizable energy level (2950, 3200 and 3450 kcal/kg). A completely randomized experimental design in a 2X3 factorial arrangement with four replications of 25 birds per treatment was applied. In order to ensure different energy intake among treatments within each strain, feed intake was daily adjusted by pair-feeding schemes. AgRoss 308 broilers had better performance and carcass yield, and presented lower abdominal fat deposition rate. In both genetic groups, the highest...

Autores: Moreira,J; Mendes,AA; Garcia,RG; Garcia,EA; Roça,RO; Nääs,IA; Dalanezi,JA; Pelícia,K.
This study evaluated the effects of strain, stocking density and dietary energy level on the feathering of broiler chickens. Four trials were carried out between September 2000 and April 2002. There were 10,685 broiler chicks from the strains Ross 308, Cobb 500, Hybro PG, Hubbard, MPK, and Isa Vedette. The bids were reared at stocking densities varying between 10 and 16 birds/m² and were given diets containing different metabolizable energy levels. Broiler feathering was evaluated either by atrributing scores from 1 to 10 to feather covering along the thigh and back (visual inspection), or by determining the percentage weight of the feathers at 28 and 42 days of age. Increasing rearing densities resulted in poorer feathering, mainly if 12 or 13 birds/m²...

Autores: Altaher,YW; Jahromi,MF; Ebrahim,R; Zulkifli,I; Liang,JB.
Although the use of probiotics especially Lactobacillus and Bifidobacteria species on growth and feed utilization in poultry production has been extensively studied, the results were inconsistent presumably because the mode of action of probiotic is multi-factorial and each probiotic strain may affect the host in a specific manner. This study investigated the probiotic effect of two strains of Lactobacillus (Lactobacillus pentosus ITA23 and Lactobacillus acidophilus ITA44; 109 cells/kg feed) isolated from mulberry (Morus Alba) silage on the growth performance, cecal microbial population, and blood cholesterol of broiler chickens.

This study evaluated the effect of different probiotics and prebiotics on the performance of broilers. One-day-old male broiler chicks from the Cobb strain (n=1,260) were randomly distributed in a 3 x 3 factorial arrangement, considering 3 probiotics and 3 prebiotics sources. Nine treatments with 4 repetitions and 35 birds per parcel were used. The results showed that there was no influence of treatment on feed intake at the different rearing phases. Better weight gain (p&lt;0.05) was seen when diet was supplemented with the phosphorylated mannanoligosaccharide-based prebiotic (MOS) compared to diets without prebiotics. Feed conversion of birds fed diets with probiotics and prebiotics was better than feed conversion of birds not receiving such additives....

Does low-protein diet improve broiler performance under heat stress conditions?
Provedor de dados: 89
Autores: Furlan,RL; Faria Filho,DE de; Rosa,PS; Macari,M.
Nutrition for broilers under high temperatures is extremely important for brazilian broiler chicken industry because the amounts of consumed nutrients and environmental temperature have great effects on bird performance and carcass quality. Among diet nutrients, protein has the highest heat increment; thus, during many years, diets with low protein level were recommended in order to reduce heat production in broiler chickens under heat stress. However, reports have shown that low-protein diets have negative effects on broiler performance when environmental temperature is high, because during heat stress, low food intake associated to a low diet protein induce amino acid deficiencies. Other studies have shown that broilers fed low-protein diets increase...

Provedor de dados: 89
Autores: Huang,S.
ABSTRACT Toll-like receptors (TLRs) are well-characterized in mice and rats, but little is known on their role in broiler chickens during acute heat stress (AHS). The aim of the present study was to estimate the change in TLR4 mRNA expression in the liver, kidney's pleen, heart, and small intestine of broiler chickens under AHS. A total of 240 healthy Arbor Acres (AA) broiler chickens were randomly divided into four groups: control group (22±1°C; 0h), HS2, HS5 and HS10 (38±1°C; 2h, 5h and 10h of heat stress, respectively). As AHS duration increased, TLR4 mRNA expression slightly decreased at HS2 and HS5, but was dramatically elevated in HS10 (p&lt;0.001) compared with the control group in the small intestine, as well as in the spleen at HS2 (p=0.001) and...

Autores: Tamehiro,Claudia Yurika; Alfieri,Alice Fernandes; Médici,Cristina; Alfieri,Amauri Alcindo.
Segmented double-stranded RNA (dsRNA) viruses were identified by polyacrylamide gel electrophoresis (PAGE) technique in fecal samples from broiler chicken. A total of 378 fecal samples from 1-7 weeks old chickens were analyzed. dsRNA with migration profile characteristic of avian rotavirus (AvRV), reovirus (ARV) or picobirnavirus (PBV) was identified in 32 (8.5%), 7 (1.8%) and 13 (3.4%) samples, respectively. AvRV and ARV occurred more frequently in chickens up to 1 month old and were related with enteritis signs. Considering only fecal samples of chickens with diarrhea, the AvRV was detected in 37.8% (14/37) and the ARV in 13.5% (5/37) of analyzed samples. AvRV was identified in only 1.5% (4/274) and ARV was not detected in normal feces collected from...

This study was carried out during 2002/2003, aiming to determine the prevalence of virulent Newcastle disease virus strains (NDV) in Brazilian commercial poultry farms. Clinical samples were obtained from the Southeastern, Southern and Central-Western regions, which comprise the main area of the Brazilian poultry production. Serum samples and tracheal and cloacal swabs of 23,745 broiler chickens from 1,583 flocks, including both vaccinated chickens and those with no vaccination information, were tested for NDV using a diagnostic ELISA kit. The seropositivity was 39.1%, and the isolation percentage by flock varied from 1.0 to 7.6%, and by region from 6.5 to 58.4%. Higher isolation rates (74.3-83.3%) were obtained after three passages in embryonated chicken...

Provedor de dados: 65
Autores: Scheuermann,Gerson Neudí; Cunha Junior,Anildo; Cypriano,Lucas; Gabbi,Alexandre Mossate.
This study evaluated a phytogenic feed additive for broiler chickens. A total of 1,632 broiler chicks were distributed into four treatments: negative control (without growth promoter); positive control (avilamycine, 10ppm + colistin, 15ppm); and two alternative treatments with 150ppm of phytogenic additive, one with a reduced Ca and P levels diet (PA-R1) and the other with lower energy, and amino acids, besides Ca and P (PA-R2). The trial was conducted with 12 replicates, each consisted of a pen with 34 birds. The alternative diets showed body weight intermediate to the two controls at 42 days, with no significant (P&gt;0.05) treatment effect on feed conversion ratio. No treatment differences (P&gt;0.05) on carcass yield and composition was observed. There...

Cryptosporidium spp. in bursa of Fabricius of broiler chickens from Uruguay
Provedor de dados: 65
Autores: Casanova,Susana; Verdes,José Manuel; Okada,Kosuke.
The presence of Cryptosporidium spp. was detected in broiler chickens of 32-40 days of age, colonizing the bursa of Fabricius. The histologic study with haematoxylin and eosin staining was done on specimens of trachea, complete intestinal tract and bursa. Samples of intestinal content were also studied using Kinyoun staining technique. All birds with signs of illness were positive to the presence of parasite, showing a hypertrophic bursa of Fabricius, filled with caseous content. The bursal epithelial cells were full of different developmental stages of Cryptosporidium spp. This note describing the presence of Cryptosporidium spp. in industrial flocks of broiler chickens, is the first report of this parasite in Uruguay

Aflatoxins and fumonisins in feed from a broiler operation system from São Paulo state, Brazil
Provedor de dados: 65
Autores: Kobashigawa,Estela; Corassin,Carlos Humberto; Franco,Larissa Tuanny; Uliana,Rômulo Dutra; Oliveira,Carlos Augusto Fernandes de.
ABSTRACT:  The aim of the present study was to assess the occurrence of aflatoxins (AFs) and fumonisins (FBs) in feed ingredients (corn and soybean meal) and finishing feed in a broiler operation system, as well was to evaluate their effect on the productivity of 20 batches of broilers produced and the histology status of broilers’ liver after slaughter. Corn samples presented the highest frequencies of AFs and FBs, at mean levels of 29.1 and 2,100µg/kg, respectively. Soybean samples presented mean levels of 1.5 and 70µg/kg for AFs and FBs, respectively. Batches of broilers receiving feed containing FB levels higher than 1,000µg/kg had lower weight gain and higher mortality rates, while those fed rations with AFs equal or above the limit of quantification...

Provedor de dados: 65
Autores: Barros,Victor Ramos Sales Mendes de; Lana,Geraldo Roberto Quintão; Lana,Sandra Roselí Valerio; Lana,Ângela Maria Quintão; Cunha,Fabio Sales Albuquerque; Neto,João Virgínio Emerenciano.
The study aimed to evaluate the use of β-mannanase and mannan oligosaccharides (MOS) to replace growth promoters in broiler diets. Four hundred male Cobb broiler chicks were used, with initial weight of 45±1g, distributed in a completely randomized design with five treatments and eight repetitions of ten birds. The treatments were: basal feed; basal feed without growth promoter; basal feed without growth promoter + β-mannanase; basal feed without growth promoter + MOS; and basal feed without growth promoter + β-mannanase + MOS. The feed intake of the birds increased in response to dietary treatments compared to basal diet during the period 1-21 days of age. A higher weight gain and improved feed conversion was found at 42 days of age among birds that had...
