Description of lesions in lambs intoxicated with sodium selenite included in intraruminal boluses: Lambs intoxicated with selenium. [PDF]

Vet Med Sci
This study evidenced the main lesions related to selenium poisoning in lambs supplemented with selenium through intraruminal boluses. The main organs affected were the lung, heart, liver, kidney, thymus, thyroid gland and reticulo‐rumen. Abstract Selenium is an essential micronutrient for ruminants, which participates in the optimal functioning of ...

A pilot investigation on the effect of induced saliva flow on digestive parameters in sheep, and a comparison with cattle

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 5, Page 1176-1186, September 2023., 2023
Abstract Sheep with a relatively low methane yield were observed to have shorter fluid and particle mean retention times (MRT). Because the application of pilocarpine, a saliva stimulant, was successful in reducing retention times in ruminants in previous studies, we applied this substance to sheep, expecting a reduction in MRT and methane yield. Three

Effects of the density of extruded pellets on starch digestion kinetics, rumen fermentation, fiber digestibility and enteric methane production in dairy cows

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 4, Page 981-994, July 2023., 2023
Abstract Dynamics of starch digestion in dairy cows fed extruded pellets differing in physical functional properties were investigated by measuring starch digestibility, post‐prandial rumen fermentation patterns, and post‐prandial duodenal starch appearance.

Effect of induced saliva flow on fluid retention time, ruminal microbial yield and methane emission in cattle

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 3, Page 769-782, May 2023., 2023
Abstract Both in vitro and animal studies indicated that a higher dilution rate is related to a more efficient microbial synthesis and a lower methane (CH4) yield. The latter could be a consequence of the former, as an increase in microbial cell synthesis offers an alternative hydrogen sink competing with methanogenesis. To test this assumption in live

Study on manipulation of ruminal fermentation using a bioelectrochemical system

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 2, Page 357-366, March 2023., 2023
Abstract The purpose of this work was to develop a two‐chamber bioelectrochemical cell to modify the metabolic activity of rumen microorganisms by applying an electric potential to the ruminal liquid. Carbohydrate fermentation changes were evaluated along with a molecular characterization by DNA sequencing of the ruminal microbial community.

Prevalence of indigestible foreign bodies and its associated potential risk factors in rumen and reticulum of domestic ruminants at Bishoftu Elfora Export Abattoir

Veterinary Medicine and Science, Volume 8, Issue 6, Page 2623-2630, November 2022., 2022
Nowadays, ingestion of indigestible foreign bodies poses serious economic loss to domestic ruminants, in a developing country mainly during the dry season due to shortage of forage, its less biodegradability and negligent waste disposal. Cross‐sectional study design was conducted from May 2021 to September 2021 on 384 domestic ruminants (171 goats, 125

Feed digestibility, digesta passage and faecal microbial biomass in desert‐adapted goats exposed to mild water restriction

Journal of Animal Physiology and Animal Nutrition, Volume 106, Issue 4, Page 721-732, July 2022., 2022
Abstract In arid and semi‐arid environments, extensively managed ruminants regularly experience drinking water shortage, especially in the dry season. The present study therefore investigated the effects of mild drinking water restriction on feed intake, feed digestibility, solid digesta passage and composition of faeces including faecal microbial ...
