Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

Desulfovibrio of the sheep rumen [PDF]
A sulfate-reducing bacterium has been isolated in pure culture from sheep rumen contents. Its properties agree in all respects tested with those ascribed to Desulfovibrio desulfuricans. The populations observed (about 10(8)/ml) are sufficient to account for published rates of ruminal sulfide production.

Nelore (N) and Nelore × Pantaneiro (NP) heifers exhibited similar grazing times, which were higher compared with Nelore × Angus (NA) heifers. Nelore heifers showed higher wither height and hip height values compared with NP heifers. The average values for NA heifers did not differ from the other genotypes. It was observed that chest depth, heart girth,

In ruminants, early rumen development is vital for efficient fermentation that converts plant materials to human edible food such as milk and meat. Here, we investigate the extent and functional basis of host-microbial interactions regulating rumen ...

Toxin Degradation by Rumen Microorganisms: A Review
Animal feeds may contain exogenous compounds that can induce toxicity when ruminants ingest them. These toxins are secondary metabolites originating from various sources including plants, bacteria, algae and fungi.

We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market
