An evaluation of the effectiveness of sumac and molasses as additives for alfalfa silage: Influence on nutrient composition, in vitro degradability and fermentation quality
In conclusion, sumac prevents proteolysis depending on its tannin content. It improves silage fermentation positively thanks to its organic acid content, while the molasses additive is effective in silage fermentation, mainly depending on the WSC level. However, it was determined that neit her additive could reduce the silage pH to the appropriate value ranges due to the low doses, and they could not mainly prevent the formation of BA.

Investigation of Factors Associated with Subclinical Infections of Giardia duodenalis and Cryptosporidium canis in Kennel-Housed Dogs ( Canis lupus familiaris )
Comp Med. 2024 Apr 2. doi: 10.30802/AALAS-CM-24-000007. Online ahead of print.ABSTRACTGiardia duodenalis and Cryptosporidium spp. are zoonotic protozoal pathogens, spread by a fecal-oral route, which can infect a wide range of hosts including but not limited to dogs and humans. Giardia was recently estimated to be present in 37% to 50% of kennel-housed dogs. Cryptosporidium infections in kennel-housed dogs have been reported in 7% to 21% of the population. The goal of this study was to define demographic factors and fecal scores associated with positive screening test cases of Giardia and Cryptosporidium in kennel-housed l...

Analysis of blood biochemistry and non-targeted metabolomics of endometritis in dairy cows
In this study, the differential markers and metabolites of healthy cows and cows with endometritis were analyzed by measuring blood biochemical indicators and immune factors using biochemical and enzyme-linked immunosorbent assay kits combined with nontargeted metabolomics. The LC-QTOF platform was used to evaluate the serum metabolomics of healthy cows and cows with endometritis after 21-27 days of calving. The results showed that glucose, free fatty acid, calcium, sodium, albumin, and alanine aminotransferase levels were significantly lower in the serum of cows with endometritis than in healthy cows (P < 0.05). Howeve...

No evidence tube entrapment distresses rodents in typical empathy tests
Anim Cogn. 2024 Apr 1;27(1):29. doi: 10.1007/s10071-024-01863-9.ABSTRACTIn the first two experiments an empty tube open at one end was placed in different locations. Male hamsters, tested one at a time, tended to stay close to the tube or in it. During the first minute of the first 4 sessions of Experiment 3, the hamster was unrestrained. If it entered the tube, it was locked within the tube. If it did not enter the tube during the first min, it was placed in it, and the tube was locked. Fifteen min later, the tube was opened, and the hamster was unrestrained for a further 20 min. The tube remained open during Session 5. H...

A preliminary analysis of the effect of individual differences on cognitive performance in young companion dogs
In this study, companion dogs under 12 months of age were tested once on two tasks purported to measure aspects of executive function: the delayed-search task (DST) and the detour reversal task (DRT). Owners also filled out the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) to evaluate how temperament influenced task performance. Contrary to prior research, performance did not improve with age on either task. However, the lack of age effects was likely the result of small sample sizes and individual differences across other factors influencing performance. Specifically, temperament differences as measured...

 Chlamydia muridarum Associated Pulmonary and Urogenital Disease and Pathology in a Colony of Enzootically Infected Il12rb2 Deficient and Stat1 Knockout Mice
Comp Med. 2024 Apr 1. doi: 10.30802/AALAS-CM-24-000002. Online ahead of print.ABSTRACTChlamydia muridarum (Cm), an intracellular bacterium of historical importance, was recently rediscovered as moderately prevalent in research mouse colonies. Cm was first reported as a causative agent of severe pneumonia in mice about 80 y ago, and while it has been used experimentally to model Chlamydia trachomatis infection of humans, there have been no further reports of clinical disease associated with natural infection. We observed clinical disease and pathology in 2 genetically engineered mouse (GEM) strains, Il12rb2KO and STAT1KO, w...
