In study are determined effects of four different mean lengths of corn silage, alfalfa haylage and total mixed ration (TMR) for lactating cows on physical effectiveness (pef), physically effective fiber content (peNDF) and total chewing activity. High correlations were found between mean particle length of forages and TMR and their physical effectiveness in lactating cows nutrition as also with physically effective fiber content. Significant effect of ration particle size on stimulating total chewing activity of lactating cows was determined.

ABSTRACT: This study evaluated the effects of the physically effective fiber (peNDF) content on nutrient composition of the total mixed ration (TMR), orts and fecal parameters in 15 commercial beef feedlots. The particle size distribution of TMR was measured adopting Penn State Particle Size Separator (PSPS). Samples were evaluated for dry matter (DM), ash, ether extract (EE), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and starch content. Fecal samples were also evaluated for pH and score. The feedlots were categorized into peNDF<20% and peNDF ≥ 20%. Data were analyzed by a model that included fixed effects of treatment and covariates (sex and genetic groups). Levels of DM, CP, EE and starch were lower in TMR with peNDF ≥ 20% (P<0.05). Fecal dry matter was higher and morning fecal pH was lower for TMR with peNDF<20% (P<0.05). Physically effective fiber changed nutrient levels in TMR, orts, fecal pH and DM. So, using PSPS and fecal parameters are practical and indirect tools for measuring fecal starch and assessing the effectiveness of the diet supplied to ruminants.

Abstract This in vitro study assessed the effects of three pine-based engineered biocarbons (CP002, CP016, CP023) that differed in particle size (&lt; 0.5, 0.5–2.0, &lt; 2.0 mm) at two inclusion levels (0.25 mg/ml and 0.5 mg/ml) on total gas and CH4 production as well as rumen fermentation parameters when added to a barley silage-based total mixed ration diet. Biocarbon products differed in bulk density, surface area, pore volume, and pH but had similar chemical compositions. The control consisted of the barley-silage diet only. In each jar, 0.5g DM of the total mixed ration was supplemented with the above biocarbon treatments. These jars were incubated for 48 hr at 39 °C. Gas samples were collected at 3, 6, 9, 12, 24, 36 and 48 hr. Data were analysed by using PROC MIXED in SAS in a randomized complete block design with treatment, rate, and particle size as fixed effects and run and replicate as random effects. Methane production was not affected by treatment (P = 0.37), inclusion rate (P = 0.57) or particle size (P = 0.39). Gas production linearly increased (P &lt; 0.01) with biocarbon. Digested DM was not affected (P = 0.23) by biocarbon addition. Additionally, treatment, rate and particle size had no effect (P &gt; 0.05) on pH, VFA and ammonia N concentrations. In conclusion, the amount of biocarbon differing particle sizes at different rates did not affect CH4 emissions but did increase gas production.
