Abstract:

Integrating trees into pasture may be an effective management tool to improve water, nutrient, and light allocation and increase total system productivity in Appalachia. We tested this hypothesis in a silvopasture near Blacksburg, VA. In 1995, black walnut and honey locust trees were planted within plots (r=3) of predominantly tall fescue pasture. Across a 12% slope, trees were planted to create treatments of low, medium, and high tree densities at shoulder, mid, and toe slope positions within plots of honey locust and black walnut. Sampling sites (n=54) under tree density and slope position c

Abstract:

Two experiments using lambs were conducted to obtain additional information on the potential nutritional value of halophyte forages for ruminants. In experiment one, Salicornia bigevolii Torr. planted in mid-March and harvested at three dates (July, August and September) replaced wheat straw (30%) in a 65% forage diet. Nutrient composition and digestibility of Salicornia forage declined with advancing maturity. Forage from the July cutting was superior to wheat straw, while that from later cuttings was approximately equal to straw. In experiment two, digestion coefficients were lower when Atri

Abstract:

This experiment examined the forage potential of hemp (Cannabis sativa) and kenaf (Hibiscus cannabinus). The objectives were to evaluate yield and forage nutritive value (i.e. NDF, ADF, ADL, IVTD, and CP) fluctuations over the course of a growing season based on planting date, morphological composition, and management. Three types of hemp (grain, fiber, and a dual- purpose type) and kenaf were planted on two dates and were sampled approximately every two weeks throughout the growing season at the University of Kentucky (UK) Research Farm in Lexington, KY.

Abstract:

Shortage of quality feed is the major constraint in livestock production, particularly under smallholder subsistence farmer s conditions in sub-Saharan Africa. Livestock production under smallholder subsistence farmers depends predominantly on communal grazed natural pastures, which are often inadequate in both quantity and quality, particularly during the dry season. In order to improve livestock production in these areas, shortage of feed must be addressed in terms of quantity and quality.

Abstract:

Mob stocking is a variation of rotational stocking known for restricting a large number of animals to a small area before being moved to new grass after a few hours. This method allows a long (90-day) recovery period but was hypothesized to diminish the nutritional value of herbage relative to continuous and rotational stocking with lesser stocking density at similar stocking rates. This thesis summarizes two studies conducted in Blacksburg and Raphine, and in Steeles Tavern, VA, respectively, at a single beef cattle stocking rate of 12 animal unit months per hectare live body weight.

Abstract:

Regardless of studies demonstrating that continuous and rotational stocking can promote equivalent animal productivities, rotational stocking is still commonly associated with the idea of intensification of production systems. Moreover, studies evaluating agronomic responses of plants to stocking methods are scarce. The objectives of the present study were to explain the effects of three stocking methods (continuous stocking - CS, lenient rotational stocking - LRS, and severe rotational stocking - SRS), combined by factorial combinations with two mean canopy heights (20 and 30 cm), on forage a

Abstract:

Thesis (MScAgric (Animal Sciences))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: Ruminants have a compound stomach system that enables them to utilize forages more efficiently than monogastric animals. However, forages alone do not contain sufficient nutrients to meet the requirements of high producing dairy cows. Forages are high in fibre and their nutrient availability depends on the degree of cell wall degradability. Improvements in forage fermentation would increase energy intake and subsequently milk production and performance by dairy cows. It is therefore important to fin

L’ensilage de maïs, fourrage principal dans les rations hivernales des ruminants à haut niveau de production, est composé de deux fractions énergétiques : l’amidon et les parois végétales. Les proportions relatives de ces deux fractions varient selon le stade de maturité de la plante à la récolte, la variété cultivée et les conditions de culture. Proposé dans les années 1990, le système de prévision de la valeur nutritive de l’ensilage de maïs, basé sur l’estimation de la digestibilité de la matière organique (dMO) dans le tube digestif total, nécessite d’être amélioré pour prendre en compte d

Abstract:

Métodos de pastejo, tanto por lotação contínua quanto rotativa, visam controlar a altura do dossel, que tem sido relacionada de maneira consistente com respostas em produtividade e valor nutritivo da forragem. O presente estudo teve como objetivo descrever e explicar variações em acúmulo e valor nutritivo da forragem, assim como em estrutura do dossel forrageiro de Brachiaria híbrida Convert HD 364 (cv. Mulato II) sob lotação contínua e rotativa, com taxas de lotação variável. O experimento foi realizado em área do Departamento de Zootecnia da Escola Superior de Agricultura \"Luiz de Queiroz\"

Abstract:

As pastagens são o principal recurso alimentar para pecuária brasileira, sendo fundamentais na viabilização dos sistemas produtivos. Fatores climáticos como temperatura e fotoperíodo têm grande importância no crescimento das plantas forrageiras, influenciando o acúmulo de forragem a distribuição estacional da produção e do valor nutritivo, fatores de grande impacto no sistema produtivo como um todo. Dessa forma, o desenvolvimento de ferramentas que racionalizem o processo produtivo das plantas possibilitando a sua predição em função dos parâmetros ambientais que o condicionam são importantes p

Der Stumpfblättrige Ampfer (Rumex obtusifolius) ist eine häufig auftretende Schadpflanze des Grünlandes. Er verdrängt wertvolle Futtergräser und beeinträchtigt die Grundfutterqualität und Futterkonservierung negativ. Zahlreiche Publikationen beschäftigten sich mit der Botanik und der allgemeinen Schadwirkung, zu den wirtschaftlichen Auswirkungen wurden bisher kaum belastbare Aussagen veröffentlicht. In 2-jährigen Felderhebungen wurden an 3 Standorten in Sachsen und Thüringen zu jeweils 4 Aufwüchsen die Parameter Abundanz, Deckungsgrad, Ertragsanteil, Trockenmasseertrag sowie Futterwert und Inh

Abstract:

This research compared the influence of pre-commercial thinning (PCT) and fertilization on forage and timber values in three managed lodgepole pine (Pinus contorta Dougl. Var. latifolia Engelm.) forests in the Interior of British Columbia (BC). Cattle (Bos taurus) were grazed in two of the forests. The respective values of treatments were compared using their land expectation value (LEV). Timber values were calculated using the Tree Interpolation Program for Stand Yields (TIPSY) growth and yield model. Cattle use was calculated by relating estimated grazing densities with TIPSY-derived canopy

Thesis (MScAgric (Animal Sciences))--University of Stellenbosch, 2011.<br>ENGLISH ABSTRACT: In vitro and in situ methods using the in sacco technique have a wide application in ruminant nutrition as they allow the degradability and quality of forages and ruminant diets to be determined quicker and at a lower cost than in vivo methods. These trials make use of artificial fibre bags, made of polyester (dacron) or nylon which are available in variable pore sizes. Results from such degradability trials are of great value to feed formulation programs such as AMTS.cattle and CPM Dairy and the m
