Stocking density, restricted trough space, and implications for sheep behaviour and biological functioning

Frontiers in Veterinary Science, 2022
Stocking density and trough space allowance can potentially impact sheep welfare during live export voyages. The aim of this study was to assess the welfare implications for sheep housed at five allometric stocking densities, with either unrestricted or ...

Size-structured populations: immigration, (bi)stability and the net growth rate [PDF]

, 2009
We consider a class of physiologically structured population models, a first order nonlinear partial differential equation equipped with a nonlocal boundary condition, with a constant external inflow of individuals. We prove that the linearised system is

A Comparison of Stocking Methods for Pasture-Based Growing-Finishing Pig Production Systems

Animals, 2020
Two alternative stocking methods (rotational and strip-grazing) were compared to continuous stocking at a stocking rate of 47 pigs ha−1 in tall fescue pastures.

Terminação de cordeiros em pastagens de azevém anual manejadas em diferentes intensidades e métodos de pastejo Finishing of grazing lambs on ryegrass swards (Lolium multiflorum Lam.) under different grazing intensities and methods

Revista Brasileira de Zootecnia, 2007
Avaliou-se o desempenho de cordeiros em pastagem de azevém anual (Lolium multiflorum Lam.) manejada em duas intensidades (moderada e baixa, 2,5 ou 5,0 vezes o potencial de consumo) e dois métodos de pastejo (lotação rotacionada ou contínua) durante 113 ...

Índice de área foliar, interceptação luminosa e acúmulo de forragem em pastagens de Cynodon spp. sob diferentes intensidades de pastejo Canopy characteristics and herbage accumulation of Cynodon spp. submitted to different grazing intensities

Scientia Agricola, 1999
Avaliou-se o índice de área foliar (IAF), interceptação luminosa (IL) e acúmulo de matéria seca em três cultivares de Cynodon spp. (Tifton-85, Florakirk e Coastcross) submetidos a quatro intensidades de pastejo (5, 10, 15 e 20 cm) estabelecidas com ...

Recria de cordeiras em pastagem nativa melhorada submetida à fertilização nitrogenada: 1. Dinâmica da pastagem Rearing of lambs in improved native pasture submitted to nitrogen fertilization: 1. Pasture dynamic

Revista Brasileira de Zootecnia, 2008
Avaliou-se o efeito da fertilização com duas doses de nitrogênio (100 e 200 kg/ha, na forma de uréia) sobre as variáveis produtivas de uma pastagem nativa melhorada (3,12 ha divididos em piquetes de 0,52 ha), tendo como controle áreas sem aplicação de N.

Effects of Grazing Management on Sediment and Phosphorus Losses in Run-off (A Progress Report) [PDF]

, 2003
In 2001 and 2002, pastures at the ISU Rhodes Research and Demonstration Farm were grazed to determine the effects of stocking treatment on nutrient and sediment loss from pastureland.
