Resumen
Fielded data from 40 sows together with obtained data from 1999 to 2005 we analysed to determine the performance of sows fed enriched diet from weaning to a service in a commercialflock. The data were on litter size at birth (LTZVT), litter size at weaning (LTZWN), weaning age (WNAGE) forrowing interval (FRINT), purity (PRTY) and reproductive life (PRODLF). Mean value of 9.44(no), 6.04(no), 31.874, 453.58d and 3.65yrs were obtained for LTZBT, LTZWN, WNAGE, FRINT and PRODLF respectively.

Resumen
In summer high temperatures are stress for sows mostly. This situation often affects the reproduction physiology in animals strongly. As a result of that the fertility and reproduction performance of sows can be reduced. High environmental temperatures and especially heat accumulation in body of the animals affect the metabolism in high performance sows. That is important in very sensitive phases in reproduction cycle of sows like heat, pregnancy and lactation. Young sows (gilts and primiparous sows) are more sensitive than older sows. This situation demands zoo- and biotechnical activities ex

The safe passage of farrowing has the big influence on the prolificacy of sows, since many piglets die directly during farrowing. Therefore, in modern industrial enterprises that use highly productive hybrid sows it is necessary to constantly monitor the passage of farrowing sows. Researches have been carried out in the reprod

AbstractThe aim of the study was to analyze infection of sows with endoparasites depending on their physiological phase and length of exploitation, as well as to determine the effects of infection on selected parameters of reproductive performance. 300 fecal samples collected from the same 75 sows in 4 phases of the production cycle (dry sows, low pregnancy, high pregnancy, lactation) were tested in the experiment.

Resumen
Abstract The modern lactating sow is a highly productive female capable of producing large quantities of milk to support large, rapidly growing litters. The associated high energy and nutritional demands are challenging to meet, especially during heat stress, when tissue loss is extensive. Supplemental lipids are efficient energy sources with a high energy density and low heat increment associated with digestion and metabolism. Besides serving as concentrated energy sources, unsaturated lipids are important sources of essential fatty acids (EFA; linoleic acid, C18:2n-6; and α-linolenic acid, C

Resumen
Thirty to forty per cent of sows in Irish herds are culled annually, one third of which are for reproductive problems such as anoestrus, anovulation and small litter size. Causes of reproductive failure include genetic, nutritional, environmental and behavioural factors. Failure to meet the nutritional requirements of sows during lactation and after weaning results in losses of liveweight and body fat (due to mobilization of body reserves) which can subsequently compromise reproductive performance. Although sows normally exhibit oestrus within one week of weaning, Sterning et al. (1990) observ

Resumen
New biotechnological procedures and the use of hormones in swine breeding are aimed at increasing the number of piglets in the litter. In small herds and groups, selected sows with 16 mammary complexes (tits) can yield up to 32 piglets, or porkers, per year per sow. In order to achieve such reproduction results, special, individual stalls for sow deliveries are used, in addition to biotechnological methods, with a warm core and floor heating, phased diet and clean facilities. The ovulation value in swine is determined by their genetic and paragenetic effects, and it is often provoked and incre

Age at puberty was delayed in gilts fed LE and ME. Backfat thickness was significantly reduced in LE and ME groups. Puberty onset was more determined by age and backfat thickness than by weight. In experiment II, all gilts that had shown normal heat within 240 days of age, were inseminated on the second estrus and given the same diet as received during their growing period.

The 1830s to the 1930s saw the rise of large-scale industrial mining in the British imperial world. This book examines how literature of this era reckoned with a new vision of civilization where humans are dependent on finite, nonrenewable stores of earthly resources, and traces how the threatening horizon of resource exhaustion worked its way into narrative form. Britain was the first nation to transition to industry based on fossil fuels, which put its novelists and other writers in the remarkable position of mediating the emergence of extraction-based life.

Texto completo
Resumen
Over the past three decades, efficient breeding and management have almost doubled the litter size of sows. Simultaneously, duration of farrowing has increased markedly. The expulsion phase of parturition in the hyper prolific sow is now 3 to 5 times longer than it was in the early 1990s. There has also been a constant downward trend in piglet birth weight, along with a similar trend in colostrum intake, which is an important risk factor for piglet mortality. Together with these trends, an increase in farrowing complications, such as postpartum dysgalactia and retention of placenta, has been reported. This paper investigates group housing of sows during gestation, farrowing and lactation, focusing on management strategies of the sow. In short, the sow needs to be given space and enrichment materials for adequate expression of nest-building behavior. Maternal characteristics may be utilized to improve the success rate of reproductive management during farrowing and early lactation. The lower piglet birth weight and compromised immunity of newborn piglets warrant investigation in the search for novel management tools. Robust breeds with somewhat lower litter size, but improved resilience and increased birth weight may be needed in the near future.

Resumen
The actions and state of an individual in one generation can affect the state of offspring in the next generation, and hence the ability of these offspring to leave offspring themselves. This chapter deals with games in this multigenerational setting. Projection matrices are used to keep track of the state and number of descendants in successive years and generations. Invasion fitness is then defined in terms of the leading eigenvalue of the projection matrix. Simple examples illustrate these concepts and show how to apply them. Reproductive value is a function that measures how the ability to leave descendants in future generations depends on the current state. The Nash equilibrium condition is reformulated in terms of reproductive value maximization. This new criterion is used to justify the fitness proxy used in the analysis of sex allocation earlier in the book. The analysis is extended to the case where offspring may inherit aspects of their mother’s quality, with a focus on the question of whether high-quality mothers should produce sons or daughters. As a second application of reproductive value maximization, the co-evolution of female preference for a particular male trait and the trait itself is analysed, with the evolution of tail length in the widowbird as an illustrative application. Mean lifetime reproductive success is used as a fitness proxy in much of the book. Its use is finally justified in this chapter, where the fitness proxy is used to analyse the evolutionarily stable age of first reproduction in a population.

Resumen
In case of significant technogenic geochemical loads on agricultural landscapes, the issue of ecological forecasting of environmental management is particularly important. Scientific studies of this issue are aimed at establishing the critical values for the components of the ecosystem, the classification of technogenic sources of hazardous substances, levels of soil contamination. This study presents a research to determine the content of heavy metals in the soils of the Ryazan region (Russia) and analyzed the level of their pollution. In the experiments organic, organomineral and mineral fer

Resumen
Los megadesarrollos turísticos de sol y playa han sido impulsados por el Banco Interamericano de Desarrollo (BID) como proyectos de estrategia de desarrollo turístico, en México nacen los Centros
 Integralmente Planeados (CIP´s) para dar orden urbano, descentralizando grandes inversiones turísticas principalmente de origen extranjeros. Son identificados ante la promoción turística por la inversión de
 insumos y tecnología. Los emplazamientos turísticos de sol y playa han crecido y destinan espacios para el hospedaje turístico temporal y permanente. Este tipo de emplazamientos destaca
