ABSTRACT.- Objective: Our objective was to evaluate 2 methods of external marker dosing, at 2 levels of forage allowance, to estimate forage intake in beef cattle. Materials and Methods: Sixteen Aberdeen Angus steers (mean age of 18 mo; 350 +- 9 kg BW), kept in individual pens, were used in a quadruplicated 4 × 4 Latin square design experiment, in a 2 × 2 factorial arrange-ment. The factors were forage allowance level (4 vs. 7 kg DM/d of alfalfa plus orchard grass haylage) and supple-ment feeding method (manual vs. automatic). A supplement consisting of 2 kg DM of pelleted corn with 1% ti- tanium dioxide (TiO2) per day was offered to each steer. Total DMI and diet DM digestibility were estimated using the dual-marker technique, with acid insoluble ash (AIA; 2 different methods) or ADL used as the internal marker. Fecal output was estimated by TiO2 concentration using feces from the daily total fecal collection (TFC) samples and others from a morning subsample. The TFC was carried out individually and daily during the last 4 d of each 21-d period. Results and Discussion: The overall mean recovery of TiO2 was 104% (SD: 0.05; range: 101-107%). Fecal subsamples obtained in the morning overestimated fecal production with no difference between dosing methods. The DM digestibility was overestimated with AIA and ADL. The estimation of DM digestibility by ADL was closer than AIA to those obtained by TFC, without differences between the 2 AIA techniques. The overestimation of forage intake using the dual-marker technique was more affected by the overvalued DM digestibility using the internal markers than by fecal production using the external marker, without the effect of the dosing method. Implications and Applications: It is viable and reliable to automatically supply pelleted corn with TiO2 for fecal production estimation. The accuracy could be improved by obtaining at least 2 fecal samples during the day. Under the current experimental conditions, ADL is more accurate than AIA for estimating DM digestibility when the diet offered to cattle is based on alfalfa plus orchard grass haylage and concentrate. © 2024 The Author MenosABSTRACT.- Objective: Our objective was to evaluate 2 methods of external marker dosing, at 2 levels of forage allowance, to estimate forage intake in beef cattle.

Abstract: Silicon (Si) can adversely affect insect herbivores, particularly in plants that evolved the ability to accumulate large quantities of Si. Very rapid herbivore-induced accumulation of Si has recently been demonstrated, but the level of protection against herbivory this affords plants remains unknown. Brachypodium distachyon, a model Si hyperaccumulating grass, was exposed to the chewing herbivore, Helicoverpa armigera, and grown under three
conditions: supplied Si over 34 d (+Si), not supplied Si (-Si), or supplied Si once herbivory began (-Si +Si). We evaluated the effectiveness of each Si treatment at reducing herbivore performance and measured Si-based defenses and phenolics (another form of defense often reduced by Si). Although Si concentrations remained lower, within 72 h of exposure to Si, -Si +Si plants were as resistant to herbivory as +Si plants. Both +Si and -Si ? +Si treatments reduced herbivore damage and growth, and increased mandible wear compared to Si. After 6 h, herbivory increased filled Si cell density in -Si ? +Si plants, and within 24 h, -Si ? +Si plants reached similar filled Si cell densities to +Si plants, although decreased phenolics only occurred in +Si plants. We demonstrate that plants with short-term Si exposure can rapidly accumulate Si-based antiherbivore defenses as effectively as plants with long-term exposure. |
