“…Ndlovu and Muchenje (2009) stated that BCS is the best indicator of cattle nutritional status by practitioners. Therefore, the low BCS values obtained in October could be due to poor pasture available in the month of October in Zambia leading to poor nutrition available for the proper nourishment of the animals during this period (Sitali et al, 2016).…”

“…Body condition was scored using a score from 1 to 5 as described by Penny, (2016); Sitali et al (2016). A score of 1 denoted a very thin bull (poor), while 5 denoted an extremely fat bull (obese) and 3 as an average BCS (good).…”

“…Variability of results from various species showed a possible influence of species or even individuals in terms of the response given to the transrectal massage method that affected the characteristics of the semen produced. Other factors such as genetics, breed, age, stress, and environmental factors have also been reported to affect the quality of the semen of bulls (Enciso et al 2011;Sitali et al 2016).…”

“…Those may cause variations in spermatozoa quality. Other factors contributing to the high proportion of spermatozoa abnormalities are breed, body condition score, age, scrotal circumference, feed quality, and stress (Sitali et al 2016). Since we could only use one banteng in this study, specific factors cannot be identified.…”

Abstract. Yoelinda VT, Arifiantini RI, Solihin DD, Agil M, Setiadi DR, Hastuti YT, Manansang J, Sajuthi D. 2023. Short Communication: Characteristics of the endangered Javan banteng (Bos javanicus) spermatozoa. Biodiversitas 24: 759-766. Morphology and morphometry of spermatozoa become essential fertility parameters in domestic and wild animals. Such morphological abnormalities can arise from genetic or environmental origins and cause fertility deprivation. Semen collection using transrectal massage has been used in several domestic and wild animals and is known to be simpler, safer, and less painful than artificial vaginas and electro-ejaculation. This study aimed to evaluate morphological and morphometrical features of the banteng spermatozoa head. The objective of this study was also, to evaluate the use of transrectal massage as a semen collection protocol. This study was conducted in Taman Safari Indonesia, Cisarua, Bogor, West Java, involving one banteng (Bos javanicus) bull. Semen samples were collected weekly, smeared, and stained with a modified Williams' staining method. This study found ten types of head morphological abnormality, comprising several major defects, with several types known to be the genetic origin. There were also nine types of spermatozoa tail abnormalities and teratoid form abnormalities. The total normal spermatozoa proportion in this study was 54.30±1.74%. Morphometric dimensions of length, width, and area head of banteng spermatozoa were 9.88±0.01 µm, 4.91 µm, and 38.12±0.05 µm2, respectively, with a tail length of 60.48±0.03 ?m. Although our result was limited by the number of samples available for the study, this first report on the banteng bull's sperm morphology and morphometry still need to be considered. The possibility of transrectal massage use for banteng semen collection protocol demonstrated in this study may be helpful to support the conservation approach in terms of breeding program strategy.
