ABSTRACT: The objective of this research was to characterize the efficiency and convenience of sheep identification system and its implementation costs. Therefore we quantified the time for implementation, reading and data transfer to a management program in a manual system (earrings) and electronic system (subcutaneous transponders). Furthermore, it was evaluated the implementation costs of the traceability systems by analysis of the absorption costs and comparison between systems. It was observed that the implementation time for the manual system was shorter (2.2 s animal−1) than the electronic system (4.67 s animal−1). As for reading time, the electronic system presented shorter time (2.89 s animal−1) than the manual system (4.67 s animal−1). As for the...

SHEEP PRODUCTION IN HUNGARY – IS IT A SUSTAINABLE SECTOR?
Provedor de dados: 31
Autores: Madai,   Hajnalka; Nabradi,   Andras; Lapis,   Miklos.
The question of sustainability of agricultural production especially animal production and events leading to its development can be dated back to the second part of the last century. Sustainability is a priority subject matter as it is a core element in our existence and in the survival of the forthcoming generations. The notion of sustainability comprises three aspects: ecological, social and political and economic target systems, which by now have been supplemented with cultural and regional elements including the protection of environment, local traditions, scale of values, cultural and historical heritage. The principles of sustainable development also include the improvement of human and animal health and the maintenance of vital rural communities....

ANÁLISE ECONÔMICA E CUSTOS DE PRODUÇÃO APLICADOS AOS SISTEMAS DE PRODUÇÃO DE OVINOS
Provedor de dados: 31
Autores: Viana,   Joao Garibaldi Almeida; Silveira,   Vicente Celestino Pires.
Conhecer as diferentes metodologias, classificações, composições dos custos e indicadores econômicos se torna primordial na gestão dos sistemas produtivos. Desta forma, o objetivo do presente trabalho é apresentar uma revisão teórica sobre análise econômica e custos de produção, destacando as terminologias, etapas e composição dos custos, métodos de apropriação, indicadores econômicos e medidas de desempenho agrícola, além de exemplificar uma metodologia específica para a análise econômica da ovinocultura. Os custos de produção são variáveis desconhecidas pela imensa maioria dos produtores brasileiros. Sistema de custos é um conjunto de procedimentos administrativos que registra, de forma sistemática e contínua, a efetiva remuneração dos fatores de...

Multivariate techniques in the analysis of carcass traits of Morada Nova breed sheep
Provedor de dados: 65
Autores: Guedes,Déborah Galvão Peixôto; Ribeiro,Maria Norma; Carvalho,Francisco Fernando Ramos de.
ABSTRACT: This study aimed to use multivariate techniques of principal component analysis and canonical discriminant analysis in a data set from Morada Nova sheep carcass to reduce the dimensions of the original data set, identify variables with the best discriminatory power among the treatments, and quantify the association between biometric and performance traits. The principal components obtained were efficient in reducing the total variation accumulated in 19 original variables correlated to five linear combinations, which explained 80% of the total variation present in the original variables. The first two principal components together accounted for 56.12% of the total variation of the evaluated variables. Eight variables were selected using the...

Carcass characteristics of sheep fed with castor bean hulls in replacement of tifton 85 hay
Provedor de dados: 64
Autores: Urbano,Stela Antas; Ferreira,Marcelo de Andrade; Dutra Junior,Wilson Moreira; Andrade,Rafael de Paula Xavier de; Siqueira,Michelle Christina Bernardo de; Félix,Sabrina Carla Rodrigues.
Castor bean hulls (CBH), co-products of castor oil extraction, are high in dry matter (DM) and fiber and are emerging as alternative roughage in sheep feed. This could reduce feed costs since other sources of roughage can be more expensive. The effects of replacing Tifton 85 hay with CBH at 0, 33, 66 and 100% in the diet of sheep on the carcass characteristics, weights and yields of retail cuts and carcass measurements were studied. Twenty-eight non-castrated sheep averaging 7 ± 1.4 months of age with an initial weight of 19.5 ± 4.3 kg were slaughtered after 70 days of confinement. There was a linear decline (P ≤ 0.05) in slaughter body weight, empty body weight, hot and cold carcass weight and longissimus muscle area (LMA) as the percentage of dietary CBH...
