Procedures for the diagnosis of Br. ovis infection in rams were evaluated by examining 10 rams artificially infected by preputial inoculation. Observations were undertaken at weekly intervals for 1 year to follow changes in clinical, bacteriological and serological findings. Clinical lesions were detected in 1 ram 3 weeks after inoculation and in all rams by 8 weeks; lesions were undetectable in 3 rams at the completion of the trial. The presence of inflammatory cells in semen samples was the earliest indication of infection being demonstrated in 2 rams at 2 weeks and in all rams by 8 weeks; subsequently 86% of samples were positive. Br. ovis was detected in semen smears from 3 rams at 4 weeks but only one in all rams (at 27 weeks); overall 52% of semen smears were positive from 4 weeks onwards. Br. ovis was cultured from semen of 5 rams after 4 weeks and from all rams at 5 weeks; therafter 97% of samples were positive. All rams developed significant titres to the CFT between 2 and 9 weeks; therafter the CFT was a reliable indication of infection in 6 rams, highly suggestive in 3 and unreliable in one. By 8-10 weeks all rams developed significant titres to the IHA which were then maintained in all rams for the remainder of the trial.

Effects of Breeding for Short-Tailedness in Sheep on Parameters of Reproduction and Lamb Development.
Vet Med Sci
January 2025
Veterinary Clinic for Reproductive Medicine and Neonatology, Justus-Liebig University of Giessen, Giessen, Hessen, Germany.
Background: Sheep's tail docking is a widespread practice, which is banned or critically discussed in some countries to improve animal welfare.
Objective: The aim was to determine the influence of breeding for short-tailedness (ST) or long-tailedness (LT) in sheep on the development of reproduction parameters and lamb performance.
Method: One hundred forty-nine ewes were mated with four rams according to tail length.

Introduction: A slower adoption rate of fixed dose combinations (FDC) in diabetes management is partly due to insufficient data. This study evaluates the safety and efficacy of an FDC of dapagliflozin + sitagliptin + metformin hydrochloride extended release (XR), compared to a dual FDC of sitagliptin + metformin hydrochloride XR among patients with type 2 diabetes mellitus (T2DM) with poor glycemic control when treated with metformin monotherapy.
Methods: A total of 274 patients with T2DM were randomized (1:1) to either arm X, receiving FDC of dapagliflozin (10 mg) + sitagliptin (100 mg) + metformin hydrochloride XR (1000 mg) (Dapa + Sita + Met) tablets, or arm Y, receiving sitagliptin phosphate (100 mg) + metformin hydrochloride XR (1000 mg) (Sita + Met) tablets, and treated for 16 weeks.
RAM2: animal study for safety evaluation of the new artificial urinary sphincter uroactive on a castrated RAM model.

Article Synopsis
- The study aimed to evaluate the safety of a new electronic artificial urinary sphincter (UroActive™) in castrated rams to treat severe urinary incontinence.
- Twenty rams were implanted with the device and monitored over various time frames, while a sham group was also included for comparison.
- The results showed successful implantation with minimal complications; only two rams developed infections, but overall, the device was deemed suitable for implantation without signs of significant adverse effects.
Changes in fatty acids, vitamins, cholesterol and amino acid profiles of ram semen by freeze-thawing process.

The objective of this study was to examine the impact of freeze-thawing on the levels of oxidative stress, fatty acids, vitamins A, D, E, and K, cholesterol, and amino acids, as well as on spermatological parameters, in ram semen. Semen was collected and pooled from each of the seven rams twice a week for three weeks. The mixed semen was diluted with tris + egg yolk diluent at 38 °C (Group 38 °C) and the temperature was reduced to 5 °C (Group 5 °C).

Article Synopsis
- Environmental heat stress negatively impacts reproductive efficiency in farm animals, specifically prepubertal Ossimi ram lambs exposed to severe heat conditions in this study.* -
- The study assessed the effects of melatonin and nano melatonin treatment on various reproductive parameters, finding that both treatments improved testicular function and structure compared to a control group.* -
- Results showed significant increases in testicular volume, echotexture, and antioxidant levels in the treated groups, although testosterone levels remained unchanged.*
