Metabolic disorders in the transition period indicate that the dairy cows' ability to adapt is overstressed

Metabolic disorders are a key problem in the transition period of dairy cows and often appear before the onset of further health problems. They mainly derive from difficulties the animals have in adapting to changes and disturbances occurring both outside and inside the organisms and due to varying gaps between nutrient supply and demand. Adaptation is a functional and target-oriented process involving the whole organism and thus cannot be narrowed down to single factors. Most problems which challenge the organisms can be solved in a number of different ways. To understand the mechanisms of adaptation, the interconnectedness of variables and the nutrient flow within a metabolic network need to be considered. Metabolic disorders indicate an overstressed ability to balance input, partitioning and output variables. Dairy cows will more easily succeed in adapting and in avoiding dysfunctional processes in the transition period when the gap between nutrient and energy demands and their supply is restricted. Dairy farms vary widely in relation to the living conditions of the animals. The complexity of nutritional and metabolic processes Animals 2015, 5 979 and their large variations on various scales contradict any attempts to predict the outcome of animals’ adaptation in a farm specific situation. Any attempts to reduce the prevalence of metabolic disorders and associated production diseases should rely on continuous and comprehensive monitoring with appropriate indicators on the farm level. Furthermore, low levels of disorders and diseases should be seen as a further significant goal which carries weight in addition to productivity goals. In the long run, low disease levels can only be expected when farmers realize that they can gain a competitive advantage over competitors with higher levels of disease.

Identifying the factors governing attitude towards the e-Agriservice among dairy farmers in Maharashtra, India

Information and communication technology (ICT) projects have a great potential to revolutionise the information delivery system by bridging the gap between farmers and extension personnel. aAQUA (Almost All Questions Answered) portal was launched by the Developmental Informatics Laboratory (DIL) at Indian Institute of Technology (IIT) Mumbai, Maharashtra, India in 2003 as an information providing system to deliver technology options and tailored information for the problems and queries raised by Indian dairy farmers. To measure the effectiveness of this service the attitudinal dimensions of the users of aAQUA e-Agriservice were investigated using a 22 item scale. A simple random sampling technique was used to select 120 dairy farmers from which data were collected and subjected to factor analysis to identify the underlying constructs in this research. From the attitude items, four components were extracted and named as the pessimistic, utility, technical and efficacy perspective, which influenced the development of varied level of attitudinal inclination towards the e-Agriservice. These components explained 64.40 per cent of variation in the attitude of the users towards the aAQUA e-Agriservice. This study provides a framework for technically efficient service provision that might help to reduce the pessimistic attitude of target population to adopt e-Agriservice in their farming system. The results should also be helpful for researchers, academics, ICT based service providers and policy makers to consider these perspectives while planning and implementing ICT projects.

Meat yield and quality of Tanzania Shorthorn Zebu cattle finished on molasses/maize grain with agro-processing by-products in 90 days feedlot period

This study was conducted to evaluate the effects of feeding molasses or maize grain with agro-processing by-products on yield and quality of meat from Tanzania shorthorn zebu (TSZ) cattle. Forty five steers aged 2.5 to 3.0 years with 200 +/- 5.4 kg body weight were allocated into five dietary treatments namely hominy feed with molasses (HFMO), rice polishing with molasses (RPMO), hominy feed with maize meal (HFMM), rice polishing with maize meal (RPMM) and maize meal with molasses (MMMO). Ad libitum amount of each dietary treatment and hay were offered to nine steers for 90 days. Cooking loss (CL) and Warner Bratzler shear force (WBSF) values were determined on M. longissimus thoracis et lumborum aged for 3, 6, 9 and 12 days. Steers fed on HFMO diet had higher (P < 0.05) nutrient intake (86.39 MJ/d energy; 867 g/d CP), weight gain (919 g/d) and half carcass weight (75.8 kg) than those fed other diets. Meat of steers from all diets was tender with average WBSF values of 47.9 N cm^(−2). The CL (22.0 +/- 0.61%) and WBSF (53.4 +/- 0.70 N cm^(−2)) were highest in meat aged for 3 days followed by 6, 9 and 12 days. WBSF values for meat aged for 9 and 12 days from steers fed HFMO and RPMM diets were similar and lower than those on other dietary treatments x aging periods. Overall, molasses and hominy feed can be used to replace maize meal in feedlot finishing diets to spare its use in animal feeds.

Análisis de la competitividad del sub sector lechero de los pequeños y medianos productores frente al TLC con la Unión Europea

A través de los años y en busca de ser partícipes del fenómeno de la globalización y de la integración económica entre países, Colombia ha buscado establecer acuerdos comerciales estratégicamente adecuados para transformar la economía interna, expandirse a nivel internacional e intercambiar productos en los que no se es especializado. Ante esto, Colombia firmó el Tratado de Libre Comercio con la Unión Europea en Junio del 2012, que entró en vigencia en Agosto del 2013, y hasta el momento la situación del sector lechero ha sido crítica, pues carece del nivel de competitividad suficiente para garantizar la perdurabilidad de los pequeños y medianos productores de leche. El diagnóstico del sector lechero colombiano permite tener una visión más clara sobre las principales características de los sistemas de producción del país, es aquí donde se conocen las falencias que se presentan en el sector, pues la productividad es baja, los costos de producción son altos y los precios tienen una tendencia al alza, colocando a los productos nacionales en desventaja frente a la gran oferta internacional que invade el mercado interno con precios reducidos y con mejor calidad. Además, se identifica también que gran parte de los productores de leche son informales y por lo tanto es difícil consolidar la información referente al sector y convertirla en conocimiento para efectuar planes de cambio y transformación para mejorar la situación. Del lado contrario y actuando como principal competidor en este caso de estudio, se encuentra la Unión Europea. Su diagnóstico ubica esta zona geográfica en una posición indudablemente privilegiada: precios bajos, mejor calidad, alta productividad, entre otras características que hacen de la UE una verdadera amenaza para los pequeños y medianos productores colombianos. La sobreproducción que se presencia en esta asociación económica y política crea la necesidad de explorar otros mercados para poner a disposición dicha producción, y el Tratado de Libre Comercio con Colombia es una opción para compensar esa oferta con una demanda insatisfecha. Con el fin de conocer profundamente las implicaciones del TLC con la Unión Europea y cómo afecta este acuerdo a los pequeños y medianos productores de leche en Colombia, fue necesario abordar algunos puntos clave en la negociación establecida y a partir de estos determinar si este tratado es realmente una oportunidad para el campesino informal que se dedica a la producción de leche para el autoconsumo y/o la comercialización en veredas y pueblos, o por el contrario, es una plataforma que afecta negativamente a las 450 mil familias que viven de este oficio y que no tienen los niveles de competitividad exigidos para enfrentar una competencia extranjera tan fuerte como lo es la Unión Europea. Por último, el análisis DOFA permite crear estrategias coherentes y viables relacionando las fortalezas y debilidades de Colombia con las oportunidades y amenazas que implica tener un acuerdo de libre comercio con la Unión Europea. Estas estrategias contribuyen a mejorar la competitividad del sector en busca de garantizar una mayor perdurabilidad de los pequeños y medianos productores de leche, y de esta manera se logrará no sólo aprovechar este acuerdo comercial, si no también conquistar otros mercados internacionales con un producto de mejor calidad.
