Pełny tekst źródłaThis work does a study on dairy farms in western Parana in order to (1) form an understanding of the social, economic, managerial and technological characteristics present in the property; (2) implement in software an evaluation model of reproductive efficiency of dairy herds and (3) evaluate the acceptance of the producers to the use of software. For it was carried out a descriptive quantitative research with 100 producers of Medianeira, São Miguel do Iguaçu and Serranópolis do Iguaçu, in the western state, seeking, based on statistical analysis, identify, among others, the practice of zoo technical bookkeeping and use of information technology.. The results showed that 90% of manufacturers stated maintain some level of control livestock, however 72% do not evaluate any performance indicator. Among the producers who keeps some livestock control, 87% they do it on paper. On average, 74% of farmers unaware of the profit margin of the activity. Both in cost control, as the livestock control and use of information systems, no significant differences were identified in the behavior of younger producers. The software developed was used for ten months in a dairy property with 150 Holstein animals race, being updated weekly with the reproductive herd events. With the use of the model can analyze 68% of herd animals (100% of the animals at reproductive stage) an extent four times greater than the range obtained by calculation formula calving interval. Training was conducted with two groups of producers of different age groups to evaluate the acceptance of the software with an emphasis on performance expectation constructs, of performance, effort expectancy, attitude for the use, facilitating conditions, self-efficacy and anxiety during use of the system. Regarding the software acceptance, the performance expectations (utility) was the aspect best rated by the producers. The self-efficacy was the appearance of lower perception, showing greater concern for producers with possible difficulties that could face during the use.

Pełny tekst źródłaO presente trabalho teve como objetivo estimar parâmetros genéticos, em uma população de bovinos da raça Nelore, para as características probabilidade de parto até os 39 meses de idade (PC39), probabilidade de permanência no rebanho (stayability), considerando três partos até 5,2 (STAY5,2) e três partos até 6,2 anos (STAY6,2), e os quatro primeiros intervalos entre partos (IEP1, IEP2, IEP3 e IEP4), tratando- as como variáveis categóricas, e para os perímetros escrotais à desmama (PED) e ao sobreano (PES), tratando-as como variáveis contínuas. Foram usados procedimentos bayesianos, em análises unicaracterística e bicaracterística, por meio dos programas THRGIBBS1F90 e GIBBS2F90. Os dados utilizados pertencem ao programa de melhoramento genético Geneplus - Embrapa. As herdabilidades para PC39, STAY5,2, STAY6,2 , PED e PES em análise unicaracterística foram 0,15, 0,20, 0,23, 0,28 e 0,36, respectivamente. Para o intervalo entre partos as estimativas de herdabilidade, obtidas em análise unicaracterística, para IEP1, IEP2, IEP3 e IEP4 foram 0,13 0,13, 0,12 e 0,17, respectivamente. Estes valores indicam que os ganhos por seleção direta em quaisquer um dos intervalos seriam pequenos.Na análise bicaracterística as herdabilidades para PC39 e PES foram 0,14 e 0,38,respectivamente. As estimativas obtidas foram de baixa magnitude, indicando que os ganhos por seleção direta em qualquer uma das características mensuradas nas fêmeas seriam baixos. Já o PED e PES apresentaram maiores valores de herdabilidades. A correlação entre PES e PC39 foi positiva e de baixa magnitude (0,25), sugerindo que a seleção para o aumento do PES de touros possivelmente levaria a pequenas mudanças na PC39. De modo geral as estimativas de herdabilidade para as características medidas nas fêmeas apresentaram baixos valores, enquanto que para as características medidas nos machos se apresentaram de moderada a baixa, de maneira semelhante à maioria dos estudos com estas características. Entretanto, o modelo de limiar foi capaz de detectar variância genética aditiva para as características em estudo, permitindo promover ganhos, embora pequenos, por seleção direta.
In the present study were obtained, in a population of Nellore cattle, estimates of genetic parameters for the characteristics probability of calving up to 39 months at age (PC39), stayability, considering three calving until 5.2 (STAY5,2) and trhee calving until 6.2 years old (STAY6,2), and the first four calving interval (CI1, CI2, CI3 and CI4), treated as categorical traits, and scrotal perimeter at weaning (EPD) and at 18 months of age (EPS), treated as continuos trait. Were used Baeysian procedures, in single and two trait analysis, by using THRGIBBS1F90 and GIBBS2F90 programs. Information from Nellore animals belonging to the Geneplus-Embrapa program was used. The heritabilities for PC39, STAY3,1, STAY3,2, EPD and EPS in single trait analysis were 0.14, 0.20, 0.23, 0.28 and 0.36, respectively. For the calving interval estimates heritabilities for CI1, CI2, CI3 and CI4 were 0.13, 0.13, 0.12 and 0.017, respectively. These values indicate that genetic gains by direct selection in any of the intervals would be very small. In the two trait analysis the heritabilities for PC39 and EPS were 0.15 and 0.38, respectively. The low values of estimates showed that small gains would be obtained by direct selection in any of traits measured in females. EPD and EPS had higher heritabilities. The correlation between EPS and PC39 was positive with low magnitude (0.25), suggesting that the selection for the increase of EPS of sires could possibly lead to small changes in the PC39. In general, estimates of heritability for traits measured in dams were low and for traits measured in males were moderate to low. This result is likely those reported in most studies with the same traits. However, the threshold model was able to detect additive genetic variance for the traits under study and can permit to promote gains, albeit small, by direct selection.

Pełny tekst źródłaIn this paper, we will present the development of the prototype of the mobile application EQUIVAPP, which seeks to connect people working in the livestock and equine industry, thus facilitating communication with a portfolio of customers and specialized services in the sector, providing a high level of confidence by offering a variety of products valued and rated by the same users. In other words, to position ourselves within the customers as an application that helps them save time and losses by having a large number of potential partners with ratings that will ensure a premium quality of the services required. Likewise, all the services they want to access in the areas of reproduction, transport, sale of balanced or special feed and veterinary services will be present in the application. The development of this project is focused on putting an end to the high level of losses registered within the sector, since most of the contacts that many of the companies have are obtained through recommendations from neighbors or neighboring workers. Likewise, the implementation of technology in a rural sector is not a big problem, since most of the families dedicated to this sector have new generations that are up to date with the use of cell phones, computers, laptops and other technological devices.
