The biofuel industry is expanding rapidly resulting in an increase in coproducts that can be used by the livestock industry. These coproducts are dietary sources of nitrogen and phosphorus that need to be efficiently converted to milk and meat and limit losses in manure. This projects examines nutrient utilization of dairy cattle fed diets using biofuel coproducts to reduce losses …

O tamanho de partícula deve ser monitorado durante todo o processo de colheita com o uso do conjunto de peneiras "Penn State Particle Size Separator". Partículas de tamanho maior dificultam a compactação impedindo a expulsão do ar (oxigênio) provocando aumento da temperatura da massa e consumo de carboidratos solúveis.

Fluid catalytic cracking, or FCC, is the last step in the evolution of cracking processes-- also introduced in 1942, just like TCC or Thermafor Cracking, during the Second World War in an effort to make high-octane number gasoline. Remember that high-octane number relates to high power as you can have higher compression ratios in the ...

Adaptação do método Penn State Particle Size Separator para capins tropicais. Lavezzo (1985) recomendou que a trituração de capim visando a ensilagem deveria procurar obter tamanho médio de 3 a 5 cm, para permitir uma melhor compactação e, por conseguinte garantindo um ambiente anaeróbico, mais rapidamente.

Samples of diets and orts were also collected on d 40 of both years of the study for determination of particle-size distribution, which was performed by sieving using the Penn State Particle Size Separator and reported on an as-fed basis as described by Heinrichs and Kononoff (1996).

Corn Silage Processing Score • Sample of corn silage is placed on sieves and shaken for 10 minutes (Ro-Tap Shaker) • Cost is $16 per sample of corn silage • Not an on-farm field test at chopping • After shaking, sub-samples are tested for starch (NIR or wet chemistry) compared to the total starch – Coarse (19, 13,9.5, 6.7, and 4.7 mm) – Medium (3.35, 2.36, and 1.18 mm)

The particle size distribution of silages and diets was determined by dry sieving using a Penn State Particle Separator equipped with three screens (diameter openings = 19 mm, 8 mm, plus the bottom pan). Approximately 250 g of feed sample was placed on the upper screen of the separator and sieved according to the procedure described by .

The Penn State Particle Separator has led to widespread measurement of forage and total mixed ration (TMR) particle size. However, a large proportion of small particles may pass through both sieves when a TMR is analyzed, and field research has suggested that both shaking frequency and sample dry matter may affect the results. The objectives of this project were to …

particle size distribution of feeds is an important part of ration formulation and nutrition management on dairies. Until recently it has been very difficult to measure the particle size on dairies (3). The Penn State forage particle size separator box consists of three or four boxes that are stacked on top of one another.

Figure 1. The Penn State Particle Separator Box consists of three boxes that are stacked on top of one another. The top box retains particles of feed or forage that are greater than 3/4 inch. The middle box retains particles between 5/16 and 3/4 inch. The bottom box has a solid bottom and retains particles under 5/16 inch.

The Penn State TMR and Forage Particle Separator (PSPS) has become a routine technique used in forage and TMR particle size evaluation. The objective of this paper is to outline the procedure to estimate particle size using the PSPS and to briefly describe how it may be used to further understand rumen fermentation and feeding behavior.
