RESUMEN Este estudio contribuye al análisis de un ciclo anual de ganadería extensiva desde una perspectiva transversal. En el trabajo se estudian los estadíos del pastoreo invernal en el semidesierto de las Bardenas, los usos y disfrutes de los puertos de la montaña y ambas cabañeras de desplazamiento entre las dos regiones geográficas y climáticas. En los resultados gráficos del análisis se observa no solo su componente de permanencia en las costumbres locales sino también las rápidas trasformaciones actuales palpables en su significación dentro del paisaje cultural de esta sociedad pirenaica. Se logra contextualizar un sistema pastoril que imperó hasta hace no mucho, no solo en Navarra sino en toda la señalada cordillera montañosa y en la depresión del Ebro. LABURPENA Azterlan honek abeltzaintza zabala urteko zikloa zeharkako ikuspegitik ikertzen laguntzen du. Lanean neguko artzaintzaren egonaldiak aztertzen ditugu Bardeako basamortuan edo mendiko larretan erabilerak eta gozamenak eta bi eskualde geografiko eta klimatikoen arteko abelbideak. Ikerlanaren emaitza grafikoetan, tokiko ohituretan iraunkortasunaren egiturak eta egungo eraldaketa azkarrak ere ikusten dira. Pirinioetako gizarte honetako kultura paisaian, aldaketa hauek haien garrantzia ikusgai daude. Ikuspuntu integraletik, artzain-errealitatearen bilakaera maila grafikoan eta antropologikoki testuinguruan ahala da. Horrela, Nafarroan eta beste toki batzuetan, gaur egungo abeltzaintza ereduaren bilakaeraren ebaluazioarekin amaitu da. ABSTRACT The work analyzes the annual cycle of extensive livestock farming from a transversal perspective. This paper concerns the studies of the stages of winter grazing in the semi-desert of the Bardenas, the uses and enjoyments of the mountain pastures and the cattle routes between the two geographical and climatic regions. Paper aims to contextualize by graphs the analysis of the customs and anthropological level the evolution of this pastoralist reality from an integral perspective and clear expository discourse. Thus, the study concludes with an assessment of the evolution, loss or conservation of character traits of this stock model in the mountain range and the Ebro Lowland.

Winter Grazing

ABSTRACT: Remnant areas of Pampas grassland have a distinct double structure. Efficiency of livestock farming on these grasslands depends on practices that are synchronized with natural variation. This study examined the changes in vegetation composition and forage mass during winter to understand the effects of grazing methods in a natural pasture with a double structure that was grazed by heifers. An experimental area in the municipality of Bagé, Rio Grande do Sul, was subjected to continuous or rotational grazing treatments, with two replicates each. Frequency of the structural composition and forage mass of the lower stratum and animal weight was measured at the beginning and end of the experimental period (June 7 to October 7, 2016, respectively). Data were analysed with PCA ordination, regression and variance analysis. Both structural composition and forage mass changed during the experimental period. Axonopus affinis and Paspalum notatum were characteristic of continuous grazing, while Mnesithea selloana and Axonopus argentinus characterized rotational grazing (the latter had the highest levels of forage mass). Although, grazing methods changed the composition of forage mass in winter, they did not affect average daily gain of the animals.

The annual cycle in coat growth and shedding rates was investigated in Holstein and Syrian x Holstein cattle (3.1-6.2% relationship to the Syrian) under natural conditions in three different climatic regions of Israel. Hair quantity, coat thickness, and hair diameter were tested monthly on an area of 100 cm2 on the thigh. 541 samples were taken during 1 year. Cows were tested in two herds in the Jordan Valley (mean annual temperature 23�C), one herd in the Coasral Plain (mean annual temperature 20.4�C), and one in the Jerusalem area (mean annual temperature 17.5�C). Hair quantity and coat thickness in the Jordan Valley were very- significantly smaller than in the other two regions. A clear cycle was observed in these three factors. Weight of hair reached the peak In January, then decreased to 50% of the maximum weight during April-Nay and increased again during May-June, reaching 75% of the maximum weight. From October hair growth continued, to the peak in January. Variations in coat thickness differed from those in weight of hair during summer, when coat thickness stayed lox and stable until autumn. Hair fibre diameter was lowest between December and March, then increased sharply until June. Hair quantity and coat thickness decreased more and faster in the Jordan Valley. These results show that day length is not the only factor influencing the annual cycle of hair quantity and coat thickness but that, apparently, the air temperature? are of influence too. In this experiment hair diameter was influenced only by variations in day length.

The Past

This subject, is like observing the panorama of a mountain range, magnificent towering peaks, but it doesn't take much duration of observation to recognize that they are still in the process of formation. The mountains consist of approaches, materials and methods and the rocky substance of information has accumulated to such a degree that I find myself concentrating on the foothills in the foreground in order to keep up with the advance; the edifices behind form a wonderous, substantive background. It's a short history for such an accumulation and much of it has been moved by the members of the societies that make up this International Federation. My panel of speakers are here to provide what we hope is an interesting scientific fare, based on the fact that there is a continuum of biological organization from biochemical molecules through macromolecular assemblies and cellular membranes to the cell itself. Indeed, this fact explains the whole range of towering peaks that have emerged progressively during the past 25 years.

Slow Decline

Conversion of native vegetation into farmed grassland in the Lake Taupo catchment commenced in the late 1950s. The lake's iconic value is being threatened by the slow decline in lake water quality that has become apparent since the 1970s.

Hill Farming

This paper is not a formal review of hill farming literature. Rather, it is my view on the critical challenges and changes that we need to deal with if mixed livestock farming on hill lands is to be successful over the next 20 years. It is my hope that industry leaders, policy makers and agribusiness managers will give consideration to these views. Some people say that it is not smart to look into the rear-vision mirror, but I do not agree. Having a better understanding of the consequences of past events can help guide future decisions and changes.
