Managing Dairy Cattle for Fertility

Journal of Dairy Science, 1970
Abstract High reproductive efficiency in dairy herds is dependent upon good management. Accurate records on the reproductive status of each cow are essential for efficient management and for diagnoses by veterinarians. No single nutrient is required specifically for reproduction alone.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Handling errors in the response: Considerations for leveraging unsupervised or incomplete data for genetic evaluations

JDS Communications
Accurate genetic evaluations rely on high-quality phenotypic data; however, measurement errors and data inconsistencies—such as those arising from unsupervised or incomplete sources—pose challenges to their reliability. This study investigates the effect

Water Metabolism of Dairy Cattle

Journal of Dairy Science, 1992
Lactating dairy cows metabolize large amounts of water and are affected rapidly by water deprivation. Total body water, half-life of body water, size of component pools, and exchanges among them have been quantitated in several studies. The data underscore the dynamic nature of water metabolism in lactating cows.

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

Journal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Nitrogen Fertilizer Application in Grass–Clover Elevated Nitrate Leaching in the Follow‐on Maize Crop

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Grass–clover and silage maize are key for dairy feed production and frequently occur within the same crop rotations. Fertilizer management in grass–clover may leave residual effects that influence both environmental outcomes and the performance of subsequent maize crops.

Perspectives of High‐Resolution Mass Spectrometry in Soil Science

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Dietary management and feeding considerations of pediatric aerodigestive and upper gastrointestinal motility disorders: A position paper by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) Neurogastroenterology and Motility Committee

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective Pediatric aerodigestive and upper gastrointestinal (UGI) motility disorders are common and may be associated with compromised nutritional status and decreased quality of life. Traditional dietary recommendations for aerodigestive and UGI motility disorders have been rudimentary and largely based upon experience and common sense ...

Separation of trichothecene mycotoxins in a matrix of hemp (Cannabis sativa L.) seed, and quantification of deoxynivalenol in hemp grain infected with Fusarium graminearum

JSFA reports, EarlyView.
Abstract Background Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production

In vitro and in sacco determination of neutral detergent fibre digestibility of treated cereal straw

JSFA reports, EarlyView.
Abstract Background Cereal straw is hardly digestible due to its complex bonds of lignin, cellulose and hemicellulose. That is why chemical treatments, such as with sodium hydroxide, may help to loosen the bonds and thus increase ruminal digestibility. Neutral detergent fibre (NDF) digestibility is a good predictor of feed intake.
