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: Despite the importance of dairy farming in Uruguay,little information on dairy systems in this country is available in the scientific literature, and management practices that influence calf welfare at the herd level have not been explored. The aims of this study were to
(1) describe the prepartum and calf-rearing systems, as well as the management practices that may influence calf welfare in pastured dairy herds in Uruguay, (2) estimate the annual calf mortality risk from birth to weaning, and (3) identify the primary clinical disease syndromes shown by the calves before death. A survey comprising a farm visit and a questionnaire was conducted on 225 randomly selected dairies with >30
milking cows, in 3 strata (31?99, 100?299, and ?300 milking cows) of 6 Uruguayan departments where dairies are concentrated. Retrospective information from July 2013 to June 2014 was collected. A descriptive analysis was performed and results were inferred into
the national dairy cattle population. Several management practices that could contribute to poor calf welfare were identified in a large proportion of farms. The annual calf mortality risk (calves that died between birth and weaning/calves born death or alive × 100,
n = 149 farms) was 15.2%. Age at weaning averaged 75 d. Farmers reported that the most common clinical syndromes were diarrhea and respiratory disease in 85.2% and 47.5% of the farms, respectively. There was no continuous veterinary advice in 61.3% of the farms, 20.0% lacked data records, 38.5% had poor drainage in the prepartum area with waterlogging after rainfall, 52.1% monitored the prepartum area ?2 times per day MenosABSTRACT: Despite the importance of dairy farming in Uruguay,little information on dairy systems in this country is available in the scientific literature, and management practices that influence calf welfare at the herd level have not been explored.
