“…For example, milk recording enables the monitoring of individual production, which ensures that cows are grouped in batches according to production, in addition to provide subsidies for culling of cows with low lactation persistence. It was observed that the use of name was the main method of animal identification in the family economy properties studied (43.5%), which may be related to the small size of the herds, since the conventional ear earring is the main method of identification in larger herds (LOPES et al, 2013). Another limiting factor for zootechnical control was the absence of routine weighing of calves, identified in 95% of the properties of this study.…”

The aim of this study was to characterize the factors associated with the growth phase of dairy cattle used in family farming. We investigated 20 family-run milk production systems located in the Conceição de Ipanema municipality, MG, Brazil. Farmers were interviewed using a semi-structured survey form containing 152 questions. The questions were aimed at characterizing the farmer, herd, and husbandry system at pre-and post-weaning phases. Data were processed by using Sphinx ® software, and descriptive analyses were performed in MS Excel ® software. The results showed strengths, including navel healing (100%), location of the calf housing above (45%) or next to the pen (35%), and existence of a sanitary calendar (90%). However, several limitations in the management of calves and heifers were identified, such as lack of zootechnical bookkeeping (55%), manual milking with calf at the foot (65%), absence of herd sizing (100%), no routine weighing of calves (95%), incorrect colostrum management (80%), non-supply of transition milk to calves (85%), and likely failure to diagnose diseases by a fraction of the farmers. Thus, training regarding adequate management practices by extension technicians is imperative, along with the formulation of public policies that comply with the aspirations of family farmers, while promoting their economic and social sustainability.

“…As a disadvantage, electronic identification of cattle has a higher fixed cost, which highlights the need to optimize the device because these costs do not depend on the number of animals identified. The higher cost of the electronic ear tag method, due to the cost of the reading device itself, may hinder its implementation in many farms (LOPES et al, 2013b). To make the implementation of the device feasible, the technological level and the number of animals on the farm must be evaluated to ensure that the costs from using the device are justified by the optimization of labor usage.…”

“…If the reading is performed twice a year, this number decreases to 175 (Table 5). The values are lower when this method is used because, according to Lopes et al (2013b), due to some peculiarities and details of the method, it demands a greater amount of labor and time. Compared to other methods studied, the minimum numbers are 487 and 244 animals, for one and two readings per year, respectively.…”

We aimed to evaluate the technical efficiency and economic viability of the implementation and use of four cattle identification methods allowed by the Brazilian traceability system. The study was conducted in a beef cattle production system located in the State of Mato Grosso, from January to June 2012. Four identification methods (treatments) were compared: T1: ear tag in one ear and ear button in the other ear (eabu); T2: ear tag and iron brand on the right leg (eaib); T3: ear tag in one ear and tattoo on the other ear (eata); and T4: ear tag in one ear and electronic ear tag (eael) on the other. Each treatment was applied to 60 Nelore animals, totaling 240 animals, divided equally into three life stages (calves, young cattle, adult cattle). The study had two phases: implementation (phase 1) and reading and transfer of identification numbers to an electronic database (phase 2). All operating expenses related to the two phases of the study were determined. The database was constructed, and the statistical analyses were performed using SPSS ® 17.0 software. Regarding the time spent on implementation (phase 1), conventional ear tags and electronic ear tags produced similar results, which were lower than those of hot iron and tattoo methods, which differed from each other. Regarding the time required for reading the numbers on animals and their transcription into a database (phase 2), electronic ear-tagging was the fastest method, followed by conventional ear tag, hot iron and tattoo. Among the methods analyzed, the electronic ear tag had the highest technical efficiency because it required less time to implement identifiers and to complete the process of reading and transcription to an electronic database and because it did not exhibit any errors. However, the cost of using the electronic ear-tagging method was higher primarily due to the cost of the device. Key words: Automation. Cattle farming. Electronic identification. SISBOV.

Cada tratamento foi aplicado em 60 animais da raça Nelore, totalizando 240 animais, igualmente divididos em três categorias animais (bezerros, novilhos e vacas adultas).

“…Two researchers recorded the time, using two stopwatches, to decrease the chance of error. The stopwatches began timing when the cattle were led to the cattle chute, continued timing during the entire weighing procedure, and were only stopped after notes had been made in the field book and the animal had completely left the trunk, as recommended by Lopes et al (2013).…”

The objective of this study was to evaluate the technical and economic efficiency of different methods of cattle weighing, and to develop mathematical equations to estimate the breakeven point for the adoption of electronic weighing, i.e., to estimate how many animals are required for the acquisition and use of an electronic scale to be economically viable. The survey was conducted in confined beef cattle, from the Federal Institute of Education, Science and Technology in the south of Minas Gerais, IFSUL DE MINAS, Muzambinho Campus, from July to December 2014. Two methods of weighing cattle were evaluated: an electronic scale and a tape measure, using a barimetric tape for dairy cattle and a barimetric tape for beef cattle, and a conventional tape measure involving the conversion of centimeters into body weight using a specific table. Thirty-three animals identified with plastic ear tags were weighed using each method. Animals of the Nellore, Senepol, Girolando, and Red-angus breeds, aged 0-1, 1-2, and 2-3 years, were weighed 402 times in total. The time taken to weigh animals with the electronic scale was the lowest, followed by that with the barimetric tape, and that with conventional tape measure with conversion. The electronic scale exhibited the greatest technical efficiency, owing to the lack of error and the lowest time required to weigh animals. However, the costs associated with the use of this equipment were the highest, which depended on the purchasing cost. The mathematical equations developed will help technicians and cattle farmers to rapidly and precisely estimate the minimum number of animals that should compose a production system to ensure economic viability for the adoption of an electronic method to weigh cattle. ResumoObjetivou-se avaliar a eficiência técnica e econômica da implantação e utilização de diferentes métodos de pesagem de bovinos e desenvolver equações matemáticas que permitam estimar o ponto de equilíbrio para utilização do método eletrônico de pesagem, ou seja, estimar a partir de quantos animais é viável economicamente a aquisição e utilização da balança eletrônica. A pesquisa foi realizada no setor de gado de corte, em regime de confinamento, do Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais, IFSUL DE MINAS-Campus Muzambinho, no período de julho a dezembro de 2014. Foram avaliados dois métodos de pesagem de bovinos: balança eletrônica e fita métrica, sendo essa nas modalidades fita barimétrica para gado de leite e fita barimétrica para gado de corte e fita métrica convencional com conversão de centímetro em peso vivo (PV), utilizando-se tabela específica para essa finalidade. Cada método foi aplicado em 33 animais, identificados com brincos plásticos auriculares, das raças Nelore, Senepol, Girolando e Red-angus, com diferentes faixas etárias (0 a 1; 1 a 2; 2 a 3 anos), sendo realizadas 402 pesagens. O tempo necessário para pesagem dos animais pelo método balança eletrônica foi o mais rápido, seguido pela fita barimétrica e fita métrica con...
