The article presents a study which examined the presence of cryptorchidism in a Marwari stallion based on the biometry of scrotum and level of testosterone. The variables considerfed include the level of blood testosterone which is validated by electrochemiluminescence method, semen sampling through artificial vaginal method and sperm concentration. A comparison of testosterone level in monorchid stallion, normal Marwaei stallion and exotic Poitou jacks is offered.

The article describes the case of a seven-year old Marwari mare with post-partum endometritis. Observations showed the results of the rectal and ultrasonographic examinations on the Marwari mare. The mare receive intrauterine treatment and parenteral antibiotic treatment, as well as oxytoxin and Prostaglandin for uterine clearance.

The article presents a study on seminal plasma protein from three different breeds of equines, namely, Marwari stallions, Zanskari stallions and exotic jacks or martina franca. Eight semen ejaculates were obtained from the equines. The gel portion of the semen was removed by filtration while the seminal plasma was separated by centrifugation. The Lowry method was used in order to estimate the total protein from the seminal plasma.

The article discusses a study conducted in 2005 at Livestock Research Station in Andhra Pradesh, India, to assess the ejaculate characteristics and fertility in Ongole bulls. The fertility and ejaculate parameters were evaluated using nine Ongole bulls of 3-6 years age and 10 ejaculates and 20 insemination doses from each bull. Significant difference between bulls and collections were noted in relation to overall mean ejaculate volume, mass activity, sperm concentration, and initial motility.

The article discusses a study that examined the size of the testes in terms of scrotal circumference and its relation with the age and body weight in Marwari stallions. The mean age of the two groups of Marwari stallions were two to five years and six to 13 years. The body weights ranged from 280 to 443 kilograms. Findings showed a correlation between age and body weight, age and scrotal circumference, body weight and scrotal circumference and age and right testicular length.
