Última An overview on the Brazilian orange juice production chain Rev. Bras. Frutic. Santos,Renato Marcio dos; Nääs,Irenilza de Alencar; Mollo Neto,Mario; Vendrametto,Oduvaldo. Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA) showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry....

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-29452013000100025 Assessing locomotion deficiency in broiler chicken Scientia Agricola Nääs,Irenilza de Alencar; Paz,Ibiara Correia de Lima Almeida; Baracho,Marta dos Santos; Menezes,Adriana Gomes de; Lima,Karla Andrea Oliveira de; Bueno,Leda Gobbo de Freitas; Mollo Neto,Mario; Carvalho,Victor Ciaco de; Almeida,Ianê Correia de Lima; Souza,Anderson Luiz de. Locomotion deficiencies in broiler production cause poor welfare and lead to change in drinking and feeding behavior with consequent loss in weight gain. This research aimed to assess locomotion deficiencies in broiler chicken by analyzing the vertical peak force on both feet during walk. A chamber was built with an inlet ramp, a horizontal walkway in the middle and an outlet ramp. In the walkway a thin mat with piezoelectric crystal sensors was placed to record the step vertical peak force of the feet while walking on the force platform. The measurement system consisted of a mat with electronic sensors and software that allowed real time recording of the forces and the processing and analysis of data. Footage was taken from two digital video cameras and... Tipo: Info:eu-repo/semantics/article Palavras-chave: Poultry production; Gait scoring; Feet force measurement; Welfare.

Broiler chickens in Brazil are generally reared from 1 to 42 days when they are exposed to procedures such as fasting, harvesting, crating and transport to slaughter. Maintaining homeostasis is of great importance for broiler survival under harsh environment especially prior to slaughter. Heat loss varies in the distinct parts of the body during the growth period, and it is related to the air temperature of the environment and to the amount of feather covering. This research aimed to study the surface temperature distribution using infrared thermographic image processing to characterize 42 day old broiler chicken surface temperature prior to slaughter. Broilers were reared for 42 days and prior to harvest and transport to slaughter the infrared surface...

Moura,Rafael de; Caldara,Fabiana Ribeiro; Foppa,Luciana; Machado,Simone Pereira; Nääs,Irenilza de Alencar; Garcia,Rodrigo Garófallo; Gonçalves,Liliane Maria Piano. ABSTRACT This study aimed to assess the prevalence and influence of urinary tract infection on the reproductive performance of sows. The animals underwent urine tests using reagent strips and diagnosed as positive or negative. They were then divided into two groups of 30 positive and 30 negative sows for urinary tract infection. Each sow was considered an experimental unit and was followed from labor to weaning. The animals were assessed for their reproductive performance (labor duration, number of live births, mummified piglets, and stillbirths, and postpartum diseases). After weaning, the weaning-estrus interval and rate of return to estrus were assessed. A thermographic camera was used to identify hyperthermia of the mammary system and its relation with...

Heat waves usually result in losses of animal production since they are exposed to thermal stress inducing an increase in mortality and consequent economical losses. Animal science and meteorological databases from the last years contain enough data in the poultry production business to allow the modeling of mortality losses due to heat wave incidence. This research analyzes a database of broiler production associated to climatic data, using data mining techniques such as attribute selection and data classification (decision tree) to model the impact of heat wave incidence on broiler mortality. The temperature and humidity index (THI) was used for screening environmental data. The data mining techniques allowed the development of three comprehensible...

Production of one day-old chick production is one of the most important segments in the poultry production business. Broiler chicken incubation environment needs to be homogeneous and adequate so hatchability and final product quality are not affected. This research aimed at evaluating environmental conditions inside a multi-stage setter in a commercial hatchery house. The incubator was split into six areas and data loggers placed in the geometric center to register temperature and relative humidity data; carbon dioxide concentration and number of colony forming units (CFU) of fungi were also sampled and analyzed; Kruskal-Wallis non-parametric test was used for statistical analysis; significant differences in temperature and relative humidity distribution...

O Brasil é o sexto maior produtor de leite do mundo, sendo que essa produção cresce a uma taxa anual 4% superior aos demais países produtores. Parte desse aumento na produção de leite deve-se ao uso de diversas tecnologias desenvolvidas para o setor, principalmente, aquelas relacionadas à genética e ao manejo do rebanho. A detecção acurada do cio em vacas é um fator limitante na eficiência reprodutiva do rebanho leiteiro, sendo considerada uma das principais deficiências na reprodução bovina. Falha na identificação do estro com eficiência ocasiona perdas para o produtor. Métodos quantitativos preditivos, baseados em dados históricos e conhecimento especialista, permitem, a partir de uma base de dados organizada, a predição de padrões com baixa percentagem...

Global warming is affecting agribusiness in its economic aspects. Therefore, the prediction of the evolution of Brazilian beef cattle production cost was made using the IPCC forecast scenario for global warming. The methodology consisted of two steps: (i) the development of a fuzzy model that estimated the grazing land capacity (RP) decrease risk as a function of the changes in the average total rain index, air temperature and increase in extension of the dry season; and (ii) the design of an algorithm for predicting the decrease in production as function of the RPfuzzy model, that results in the impact in beef cattle productivity, and consequent increase in production costs.

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-90162010000100001 Improving detection of dairy cow estrus using fuzzy logic Scientia Agricola Brunassi,Leandro dos Anjos; Moura,Daniella Jorge de; Nääs,Irenilza de Alencar; Vale,Marcos Martinez do; Souza,Silvia Regina Lucas de; Lima,Karla Andrea Oliveira de; Carvalho,Thayla Morandi Ridolfi de; Bueno,Leda Gobbo de Freitas. Production losses due to lack of precision in detecting estrus in dairy cows are well known and reported in milk production countries. Nowadays automatic estrus detection has become possible as a result of technical progress in continuously monitoring dairy cows using fuzzy pertinence functions. Dairy cow estrus is usually visually detected; however, solely use of visual detection is considered inefficient. Many studies have been carried out to develop an effective model to interpret the occurrence of estrus and detect estrus; however, most models present too many false-positive alerts and because of this they are sometimes considered unreliable. The objective of this research was to construct a system based on fuzzy inference functions evaluated with a...

The objective of this work was to evaluate the effects of alkaline solution marinades on the characteristics of pork subjected to post-mortem pH decrease in pig muscle. The pH of carcasses was measured in a commercial slaughterhouse (n = 526), 45 min after slaughtering (pH45) and, then, the carcasses were divided into the groups with pH45<5.7 or pH45&gt;5.7. Ten samples of the longissimus dorsi muscles of each group were collected and distributed in an entirely randomized design, in a 2x4 factorial arrangement, with two conditions (pH45<5.7 or pH45&gt;5.7), and four marinade solutions: TC, no marinade; TM1, sodium bicarbonate and sodium chloride; TM2, sodium tripolyphosphate and sodium chloride; TM3, sodium bicarbonate, sodium...

The relationship between thermal environment and chick performance has widely been evaluated, however the consideration that the assessment of the comfort may be estimated by interpreting both amplitude and frequency of bird vocalization under tropical housing conditions is a new concept. This research had as objective of estimating thermal comfort for chicks during the heating phase using this new concept. An experiment was carried out inside a climate controlled chamber (A) for establishing the behavioral pattern related to environmental temperature limits. Forty five chicks were reared inside a 2.3 m² box. A video camera was placed 2.0 m above the birds and the images were captured and registered in a computer. From the pattern determined in the...
