Sheep urination frequency, volume, N excretion and chemical composition: Implications for subsequent agricultural N losses [PDF]

, 2020
Ruminant urine patches are potential sites of reactive nitrogen (N) loss to the environment. Quantification of N losses from grazed grasslands requires measurement of the frequency of urine deposition, as well as its volume and chemical composition ...

Ecotoxicological Evaluation of Soil Irrigated With Cattle Slaughter Effluent Disinfected With Peracetic Acid Using the Bioindicators Eisenia fetida and Vibrio fischeri

CLEAN – Soil, Air, Water, Volume 54, Issue 2, February 2026.
Cattle slaughter effluent disinfected with peracetic acid increased toxicity to E. fetida and V. fischeri and increased soil degradability. Cattle slaughter effluent did not demonstrate toxicity to V. fischeri. ABSTRACT The increasing volume of effluents generated by slaughterhouses is driving studies that seek sustainable alternatives for their reuse ...

Agronomic Characteristics, Chemical Composition, and Digestibility of Different Biomass Sorghum Hybrids

Advances in Agriculture, Volume 2026, Issue 1, 2026.
Biomass sorghum is notable for its high dry matter (DM) yield, making it suitable for silage production. However, hybrids with higher biomass production often show lower nutrient digestibility due to a greater proportion of stems. This study aimed to evaluate the agronomic performance, chemical composition, and fiber digestibility of five biomass ...

A Dietary Blend of Synbiotic and Organic Acids has been Demonstrated to be Beneficial for Nile Tilapia Fingerlings

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
Abstract Zootechnical additives are widely used in animal diets to enhance health and performance throughout different production stages. This study evaluated the effects of a blend of synbiotic and organic acids on Nile tilapia fingerlings. The investigation assessed growth performance, enzyme activity, proximate composition, and tissue histology.
