Abstract

Testes are male reproductive organs which are responsible for producing spermatozoa and steroid hormones. This study aims to determine the histology and histomorphometry structure of bali duck testes in the grower phase at the age of 12 weeks in one of the farms in Mengwi District, Badung Regency. The number of samples used in this research was 10 male bali ducks that were in good health. There are two examination methods carried out, namely the qualitative descriptive anatomical structure and histology examination method and the quantitative histomorphometry examination method of bali duck testicles which are analyzed using the One-Sample T-test with a confidence level of 95%. The results of this study show the anatomical structure of the bali duck testicles which are located in the abdominal cavity, between the kidneys and the lungs. The pair of testicles have the shape of a bean and are cream colored. The results of research on the histological structure of bali duck testes consist of seminiferous tubules, interstitial tissue, leydig cells, and tunica albuginea. The results of histomorphometry measurements of bali duck testes showed that the wall thickness of the seminiferous tubules was 23.6760 ± 1.4425 (µm), the number of seminiferous tubules was 421.1000 ± 56.1396 and the thickness of the tunica albuginea was 29.5000 ± 5.048 (µm). Considering the importance of knowledge about the structure of bali duck testicles, it is recommended for future researchers to examine the structure and histomorphometry of bali duck testicles at different ages in the growing phase.

Abstract

Each organ, tissue, or body part of balinese cattle in each phase has a different speed or growth rate. The growth rate of the animal's body can be known based on the growth pattern of each body size. This study aims to determine the growth rate of male balinese cattle during fattening. The research sample used was 20 male balinese cattle from Abdi Pertiwi Livestock Farmer Group, Gerokgak, Buleleng, Bali. This study used purposive sampling method and data collection was done with saturated sampling technique. Measurements were taken once a month with three measurements as replicates for three months. The data obtained were analyzed by power regression with the equation model used is Y = aXb. The results of the power regression analysis showed a significant difference (p<0.05) in each growth rate of body length and height of male balinese cattle. The highest growth rate or has the greatest growth potential is head length, followed by neck length, body length, hip height, and shoulder height. Based on the results obtained, it can be concluded that there are significant differences in the growth rate of body length and height of male balinese cattle during fattening. Further research needs to be conducted on the growth rate of body length and height of male balinese cattle until the time the cattle are slaughtered, so that it can be known with the help of a researcher.

Abstract

Bali cattle are native Indonesian germplasm originating from the island of Bali, and are widely kept by farmers due to their many advantages. Growth can be assessed as an increase in height, length, weight, and body circumference, which occurs in young cattle. This study aims to determine the growth rate of body circumference of male Balinese cattle during fattening and to describe the growth of muscle and fat in the cattle's body. A total of 20 male Balinese cows aged 11-22 months were used as research samples. Data were collected using saturated sampling technique, namely measuring the body circumference of fattened male Balinese cattle in Abdi Pertiwi Livestock Farmer Group, Gerokgak, Buleleng. The data obtained were analyzed with power regression analysis to determine the growth rate of body size of Balinese cattle. The results of power regression analysis showed that the overall correlation coefficient was very significant (p<0.05) in each size of front neck circumference, back neck circumference, chest circumference and hip circumference of male Balinese cattle. Each dimension of body circumference has a different growth rate. Based on these results, it can be concluded that there are differences in the growth rate of body circumference of male Balinese cattle during fattening. The growth rate of body circumference of male balinese cattle shows that the back neck circumference and front neck circumference have higher growth potential than hip circumference and chest circumference.
