Texto completoTo elaborate mathematical models, aiming the optimization of cost-benefit ratio and define nutritional strategies considering performance, carcass caracteristics and market variables, was carried out an experiment with female broilers chickens. It was evaluated six nutritional programs for each phase of growth (pre-starter, starter, growth I, growth II and withdrawal). The treatments were based on six levels of metabolizable energy corrected to nitrogenm balance (AMEn), keeping the AMEn:nutrients ratio. Using as a control treatment (T4), nutritional levels acording to Rostagno et al. (2005), the others were calculated - -15%(T1), -10%(T2), -5%(T3), +5%(T5) and +10%(T6) compared to the standard program. For each treatment, was used six replicates with thirty birds, in a completely randomized design. Carcass and performance characteristics were evaluated at 35, 42 and 49 days of age and, after obtained the regression equations, it was elaborated an economic analysis to establish the best nutritional levels in each market situation. It was concluded that the improvement in performance due to increased nutrient density of diets of broilers female should not be interpreted as increased profitability. Thus, mathematical models are useful to establish the relationship between variables of importance and essential for evaluating and determining nutritional programs and manner of commercialization of birds suitable for profit maximization. The developed mathematical models are an important tool, because they allow prediction of variables such as weight gain, feed intake and feed conversion and the optimization through nutritional levels and slaughter age, according to market situations.

Texto completoThis study was carried out to elaborate surface response models, by using data from literature obtained through systematic review, to predict weight gain, feed intake and feed conversion according to metabolizable energy levels, slaughter age, rearing temperature and broiler chickens sex. The equations were used to develop a program in Microsoft Excel® and, with Solver tool, determine the values of the model variables that promote maximum profits and performance. After, it was carried out two experiments, the first one with males and the second one with females, to elaborate mathematical models, by using empiric data, to optimize the cost-benefit relationship and define nutritional strategies considering performance, carcass characteristics and market variables. The treatments were based on six levels of metabolizable energy correct to nitrogen balance (AMEn) in each feed phase, keeping the AMEn:nutrients relationship following Rostagno et al. (2005) recommendations. Carcass and performance characteristics were evaluated at 35, 42, 49 days of age and, after obtained the regression equations, it was elaborated an economic analysis to establish the best nutritional levels in each market situation. In conclusion, feed formulations that look for maximum performance and/or minimum cost result in different diets that those formulated to look for maximum economic outcome. The developed mathematical models, based on either data from literature or experimental data, are an important tool, because they allow prediction of variables such as weight gain, feed intake and feed conversion. Besides, they are useful to optimize profit through nutritional levels, slaughter age and rearing temperature adaptation, according to market situations and birds sex.

Texto completoIt was evaluated six different nutritional plans based for each phase of growth of broilers (pre-starter, starter, growth I, growth II and slaughter) and with the obtained data were developed regression equations to predict weight gain, feed intake, feed conversion, productive efficiency index, energy consumption, caloric conversion and stock-breeding feasibility in terms of nutrient levels in the diet. Nutrition programs accounted for -15%, -10%, -5%, control, +5% and +10% with the control treatment based on nutritional levels indicated by Rostagno et al. (2005) and the others were calculated from the control. The experimental design was completely randomized with six treatments and six replicates of thirty birds each, totaling 1080 birds. To perform the economic analysis a program was developed in Microsoft Excel ® for, with the help of the Solver tool, optimize the relation cost-benefit and to define nutritional strategies considering performance characteristics, carcass and market variables. It was evaluated the performance characteristics and carcass at 35, 42 and 49 days old and, after obtaining the regression equations was carried out economic analysis, through simulations of market scenarios, to establish the most appropriate nutritional levels in each situation. It was concluded that the increase in nutrient levels of diets promote improved performance in broilers, although the yield of carcass and commercial cuts are little influenced. In addition, the formulation that provides maximum profit increased profitability in the production of broiler chickens and are mainly influenced by the variables age at slaughter and product to be marketed. The improved performance of birds with increasing levels of nutritional food does not mean an improvement in economic outcomes. Thus, mathematical models are useful to establish the relationship between variables of importance and essential for evaluation and determination of rearing conditions and adequate nutrition for greater profitability in the productive system.

Texto completoThe Artificial Neural Networks have been used with success for the description and modeling of processes in the most several areas of the knowledge, from economy, administration, artificial intelligence and even control of complex industrial processes. The process of chilling of chickens for immersion in cold water ("chillers") is complex and difficult to be modeled phenomenologicaly, because it involves transfer of heat, mass and transient regime, besides a great number of variables. In this work several architectures of artificial neural networks were used in the description and modeling of the process of chilling of the chickens, foreseeing the final temperature and the growth of weight of the carcasses. Also for comparison effect they were used an empiric model proposed by CARCIOFI & LAURINDO (2007) to describe the absorption of the water for the carcasses and the chilling model according to Newton's Law for the temperature of the carcasses. Different situations were tested changing the numbers of neurons of the entrance and hidden layers, and the number of layers. The data used were supplied by the SADIA - Toledo company for training and validation of the net. For the model twenty-five entrance variables were selected, as weight of the carcass, temperature before the chillers, temperature of the propilenoglicol shirt, flow of water in each module of the tanks, time of chilling and temperature of the renewal water, bubble intensity and amount of ice. The results obtained by the neural network and for Newton's Law they were not efficient to represent the final temperature of the carcass. The neural networks and the empiric model of CARCIOFI & LAURINDO (2007) went very efficient to esteem the amount of water absorbed for the carcasses. The obtained results showed that the net type with 4 x 12 x 4 neurons in the entrance layer, first and second hidden layers respectively was the best to represent the investigated system.
As Redes Neurais Artificiais têm sido empregadas com sucesso para a descrição e modelagem de processos nas mais diversas áreas do conhecimento, desde economia, administração, inteligência artificial e até controle de processos industriais complexos. O processo de resfriamento de frangos por imersão em água gelada ( chillers ) é complexo e difícil de ser modelado fenomenologicamente, pois envolve transferência de calor, massa e regime transiente, além de um grande número de variáveis. Neste trabalho foram empregadas diversas arquiteturas de redes neurais artificiais na descrição e modelagem do processo de resfriamento dos frangos, prevendo a temperatura final e o ganho de peso das carcaças. Também para efeito de comparação foram empregados um modelo empírico proposto por CARCIOFI & LAURINDO (2007) para descrever a absorção da água pelas carcaças e o modelo de resfriamento segundo a Lei de Newton para a temperatura das carcaças. Foram testadas diferentes situações alterando-se os números de neurônios das camadas de entrada e intermediária, e o número de camadas. Foram utilizados dados fornecidos pela empresa SADIA Toledo para treinamento e validação da rede. Para o modelo foram selecionadas vinte e cinco variáveis de entrada, como peso da carcaça, temperatura antes do resfriamento, temperatura da camisa de propilenoglicol, vazão de água em cada módulo dos tanques, tempo de resfriamento e temperatura da água de renovação, borbulhamento e quantidade de gelo. Os resultados obtidos pelas redes neurais e pela Lei de Newton não foram eficientes para representar a temperatura de saída da carcaça. As redes neurais e o modelo empírico de CARCIOFI & LAURINDO (2007) foram muito eficientes para estimar a quantidade de água absorvida pelas carcaças. Os resultados obtidos mostraram que a rede tipo 4 x 12 x 4 neurônios na camada de entrada, primeira intermediária e segunda intermediária respectivamente foi a que melhor representou o sistema investigado.

Texto completoThis experiment was carried out to evaluate the effects of supplementary with Sodium Bicarbonate (NaHCO3) and Potassium Chloride (KCl). In the preslaughter drinking water for broilers, on evolutions were performed or emptying of the gastrointestinal tract, water intake and carcass parameters. It was used CobbXCobb 500, 648 birds, receiving the following treatments: (T1) no salts, (T2) 0.15% NaHCO3, (T3) 0.30% NaHCO3, (T4) 0.45% NaHCO3, (T5) 0.15% KCl, (T6) 0.30% KCl, (T7) 0.45% KCl and (T8) with no water access, adding up to 8 treatments with 9 repetitions each. The diet utilized for all treatments was isonutritive, with formulation based on corn and soy. The experimental period started on the 46th day of age with treatment being administered 12 hours prior to beginning the slaughter. To standardize the feed intake, broilers were left 3 hours without feed gaining access again for one hour before starting the slaughter. After the standardization period, the food was again withdrawn to process the slaughters. At this point each broiler was weighed individually, and gastrointestinal content conditions and carcass parameters were set at zero time. From this moment on, one broiler per repetition was again weighed and slaughtered with 2, 4, 6, 8, 10 and 12 hours of fasting, respectively. With the exception of T8, water supply was unlimited during all the experiment. Measurements of water consumed was done through graded reservatories. Water intake increased significantly with the addition of the salts, no matter which one, at the end of 24 hours (P=0.0463). Weight loss increased linearly with the fasting period, it was greater in broilers with no access to water (P<0.0001, r²=0.75) when completing 12 hours of fasting. Regarding carcass parameters there were no difference between significant treatments, as well as differences found in the emptying of the digestive tract sections, crop plus gizzards and intestines, did not suffer significant effect during the treatments. The content of the total dried matter of the section of crop plus gizzard, regression of analyses, considering the treatments with and without water (T1 and T8), (T1) presented a quadratic regression (P=0.0005, r²=0.60) and (T8) was linear along the time (P=0.0001, r²=0.28). For the content of total dried matter of the intestines, both the broilers that received water (T1) and those that did not, presented a quadratic regression on the emptying with (P=0.0326, r²=0.53) and (P=0.0092, r²=0.52) respectively. This shows that under the conditions this experiment was performed, the use of salts increase water intake, and the dried matter content in the digestive tract as well as the bodily weight loss suffer significant influence as the broiler’s fasting time increased.

Desde 2004 o Brasil é o líder nas exportações de carne de frango. Dada a importância deste setor na economia brasileira, é fundamental garantir a inocuidade desse alimento, através do controle e monitoramento das etapas de produção suscetíveis à contaminação, como o pré-resfriamento. O presente trabalho objetivou avaliar as alterações da carga microbiana nas carcaças de frango e na água residente do chiller em um sistema de pré-resfriamento por imersão em água após 8 horas e 16 horas de processamento industrial, e embasar discussão sobre a determinação do Ministério da Agricultura, Pecuária e Abastecimento de esvaziamento completo, limpeza e desinfecção de cada tanque desse sistema ao final de cada 8 horas. Foram colhidas para as análises, carcaças antes e após o pré-resfriamento (mesófilos, Enterobacteriaceae, coliformes a 35°C e E. coli), além de amostras de água tratada usada no abastecimento do sistema e de água residente do chiller (mesófilos, coliformes a 35°C e E. coli). Foram colhidas amostras (carcaças e água) ao final de 8 horas e de 16 horas de trabalho. Os resultados obtidos não justificam a determinação de se esvaziar o chiller após 8 horas, podendo esse período ser prolongado para 16 horas, já que todas as análises microbiológicas, tanto das carcaças quanto da água, mostraram não haver diferença estatística significativa nas contagens dos indicadores microbiológicos avaliados. Tais dados conferem um suporte técnico-científico para discussão sobre alteração da legislação federal no tocante à etapa de préresfriamento por imersão de carcaças de frangos em água
Since 2004 Brazil remains the leading exporter of chicken meat. Due to the importance of this sector in the Brazilian economy, it is essential to ensure the food safety produced by controlling and monitoring the production stages susceptible to contamination, such as the chilling. This study aimed to evaluate changes in microbial load on chicken carcasses and chilling water residing in immersion chilling system in water after 8 and 16 hours of industrial processing. It is also an objective to underlie the discussion on the Brazilian Ministry of Agriculture Livestock and Food Supply normative that determines complete empty, clean and disinfection of each tank of the system at the end of every 8 hours. Prechill and postchill carcasses were obtained and analyzed for mesophiles, Enterobacteriaceae, coliforms at 35°C and Escherichia coli. Samples of clean water consumed in the system and the chiller water were also taken and analyzed for mesophiles, coliforms at 35°C and E. coli. The results obtained do not justify a determination to empty the tank after 8 hours and thus this period could be extended to 16 hours, as all microbiological testing of both the water and the carcasses showed no statistically significant difference in scores of microbiological indicators evaluated. These data give a technical and scientific support for discussion of change in federal law regarding the management of the water in a immersion chilling system during poultry slaughter

Este estudo foi realizado para avaliar o efeito da temperatura ambiente sobre o desempenho e características de carcaça de frangos de corte dos 22 aos 42 dias de idade. Foram utilizados 336 frangos machos da linhagem Avian Farm, com peso médio inicial de 624 g, distribuídos em delineamento experimental inteiramente casualizado, com quatro tratamentos (16, 20, 25 e 32 oC), sendo o tratamento 1 constituído de 12 e, os demais, 24 repetições, todos com quatro aves por unidade experimental. Os tratamentos influenciaram o ganho de peso, o consumo de ração e o consumo de energia metabolizável, que aumentaram, de forma quadrática, até as temperaturas estimadas de 24,4; 19,1; e 19,1 oC, respectivamente. A conversão alimentar também variou de forma quadrática, reduzindo-se até a temperatura estimada de 26,3 o C. Os tratamentos influenciaram, de forma quadrática, os pesos absolutos da carcaça, do peito e da coxa, que aumentaram até as temperaturas estimadas de 25,3; 24,0; e 26,3, respectivamente. O rendimento de carcaça aumentou e o de peito reduziu, de forma linear, com a elevação da temperatura de 16 até 32 oC. O ambiente térmico influenciou o rendimento de coxa, que variou de forma quadrática, aumentando até a temperatura estimada de 18,7 oC. Os pesos absoluto e relativo de proventrículo não foram influenciados pelo ambiente térmico. No entanto, os pesos absolutos do coração, do fígado e da moela e os relativos do coração e da moela foram influenciados pelos tratamentos, sendo mais pesados no ambiente frio (16 oC) e mais leves no ambiente quente (32 oC). Os pesos relativos do fígado e do coração diminuíram, de forma linear, com o aumento da temperatura de 16 até 32 o C. Concluiu-se que os melhores resultados de desempenho e de pesos absolutos de carcaça, peito e coxa são obtidos quando as aves são criadas em temperaturas ambientes entre 23,6 e 26,3 oC e que temperaturas ambientes abaixo ou acima desses valores influenciam, negativamente, o ganho de peso e os pesos absolutos de carcaça, peito e coxa.
This study was carried out to evaluate the effect of environmental temperature on the performance and carcass characteristics of male broilers from 22 to 42 days of age. Three hundred third six Avian Farm male broilers, with average initial weight of 624g were used. The animals were distributed in a randomized experimental design with four treatments (16 , 20, 25 and 32o C). Treatment 1 was constituted by twelve replications with four birds per experimental unity, and the others were constituted by twenty four replications with four birds per experimental unity. The environmental temperatures influenced the weight gain, and the feed and metabolizable energy intakes, that increased in a quadratic way up to the estimated temperatures of 24.4, 19.1, 19.1oC respectively. The feed:gain ratio also changed in a quadratic way, decreasing up to the estimated temperature of 26.3o C. The treatments influenced in a quadratic way the absolute weight of carcass, breast and thigh that increased up to the estimated temperature of 25.3, 24.0 and 26.3oC respectively. The carcass yield increased while the breast yield decreased in a linear way with the increase of the environmental temperature from 16 to 32o C. The thigh yield changed in a quadratic way, increasing up to the estimate temperature of 18.4o C. The absolute and relative weights of proventriculus were not influenced by the treatments. However, the absolute weights of heart, liver and gizzard, and the relative weight of heart and gizzard, were influenced by the treatments, being greater in the cold environment (16oC), and smaller in the hot environment (32oC). The relative weight of liver and heart decreased in a linear way with the increase of temperature from 16 to 32oC. It was concluded that the best results for performance and the absolute weight of carcass, breast chest and thigh are obtained when the birds are raised in environmental temperatures between 23.6 and 26.3o C, and that environmental temperatures bellow or above these values influence negatively the weight gain and the absolute weight of carcass, breast and thigh.

Texto completoThe objective was to evaluate the performance and carcass yield of different strains and sexing of broilers. The study was conducted at UTFPR with 576 birds of Cobb, Ross and Hubbard, arranged as male, female or mixed sexing, arranged in a completely randomized design (DIC) in a 3 x 3 factorial (strains x sexing), with four replications in each treatment and 16 birds in each experimental unit. Conducted daily monitoring, with weighing and calculation of feed intake and feed conversion weekly. At slaughter, carcass yield and cuts of each treatment was performed. Data were used from 141 slaughtered batches from February a December, 2012, relating to integrated poultry cooperative in the Southwest Region of Paraná, with the performance data of the same lines and sexagens producers in other comparative. For data analysis using the statistical program Assistat. Body weight, weight gain, feed intake and feed conversion were significantly on over the course of the evaluated phases differences, but in the end there were no significant differences. The performance of male presented superior in all parameters. Carcass yield was not observed significant differences between strains and sexagens birds but for some highlights cuts to Cobb. On data from the batches Hubbard provided higher mortality, body weight, daily weight gain, feed efficiency, productive efficiency and density. There was interaction between strain and sexing, presenting the best male Hubbard animal performance. There are differences between animal husbandry and sexing strains used in poultry production.
