Background: The development of local Bali cattle in ex-situ areas allow for the formation of new qualitative phenotypic characteristics. The aim of this study is to characterize Bali cattle that have been created in Jambi Province’s ex-situ environment in several of rearing areas. Methods: A research sample of 478 Bali cattle from Muaro Jambi (MJB) district, Sarolangun (SLG) district, Tanjung Jabung Timur (TJT) District, Jambi City (KJB) and PTPN VI were surveyed. The qualitative phenotype characteristic observed were pattern of head color, dominant head color, inner-ear color, forehead color, side-lip color, horn shape, body-color pattern, dominant body color, back-line color, under-belly color, sock color, rump color and tail color. The frequency and percentage of each qualitative characteristic were calculated using the PROC FREQ function of SAS software version 9.0, resulting in a cross-tabulation of the qualitative characteristics observed in Bali cattle at various locations. Then, PROC CORESP performs multiple correspondence analysis (MCA) between the qualitative characteristics of the variables. The resulting plot depicts the graphical relationship between variables. Result: Research results based on sex showed that only white lower lip and black inner ear were characteristic of the head found to be common, while black backline, light-brown underbelly, white rump and black tail hair were common characteristics for the body. Head phenotype based on district showed that white lower lip and white-black inner ear could be found in male Bali cattle while white lower lip and abnormal horn characteristic could be found in females. Body characteristic analysis showed three-color pattern to be common in male Bali cattle while black backline, white feet and white rump were common characteristics found in females. These characteristics can therefore be seen as differentiating characteristics between sex and district of origin of Bali cattle.
Background and Aim: Among several factors, the sperm quality of poultry is affected by the rooster's body size and the availability of antioxidants like vitamin E. This study aimed to determine the effect of dietary vitamin E supplementation on rooster sperm quality through a meta-analysis. Materials and Methods: After verification and evaluation, a total of 19 articles were included in this study. Data, including dietary vitamin E, semen volume, concentration, total sperm cells, pH, motility, viability, percentage of dead and abnormal sperm, vitamin E sperm content, malondialdehyde (MDA) content, and testosterone levels, were tabulated in a database; these were subsequently analyzed using mixed modeling with vitamin E dose as a fixed effect and study identity as a random effect. Results: Dietary supplementation level of vitamin E significantly (p<0.001) affected sperm concentration, significantly affected motility (p<0.001), significantly affected sperm vitamin E (p<0.001), significantly affected viability (p<0.001), and significantly affected chicken sperm fertility (p=0.001). Vitamin E administration also significantly reduced the number of sperm cell deaths (p<0.001); however, increased dietary levels of vitamin E did not affect semen volume (p=0.853), pH (p=0.951), MDA (p=0.542), the percentage of abnormal sperm cells (p=0.343), nor testosterone levels (p=0.063). Conclusion: Dietary vitamin E supplementation is recommended for male chickens since it generally enhances the quality of their sperm.
West Sulawesi Province has oil palm plantation areas that have the potential to be integrated with beef cattle. This study aims to collect data on feed availability from oil palm plantation waste and the carrying capacity of beef cattle development in West Sulawesi Province. The research method used is the desk study method that uses secondary data from Statistics Indonesia in 2022 related to oil palm plantations, palm oil production, and beef cattle populations, as well as research data relevant to this study. The data collected were analyzed descriptively. The results showed that West Sulawesi Province has oil palm plantation areas in 4 districts (Polewali Mandar, Mamuju, Central Mamuju, and Pasangkayu). The availability of dry matter from the plantation and palm oil processing waste is 479,554.04 Tons DM/year with a capacity of 210,330.72 LU/Year and can meet the needs of 317.61% of the beef cattle population from four districts. The index of feed availability from palm oil waste was highest in Pasangkayu Regency, with dry matter production of 11,298.8 tons DM/year. West Sulawesi Province has the potential to support the development of beef cattle with an integrated system of palm oil and cattle.
Indonesia is a tropical country with a hot climate. In tropical nations such as Indonesia, heat stress is a key reason for the reduced productivity of dairy cattle. Heat stress is a combination of internal and external stimuli that affects an animal, raises its body temperature, and causes it to react physiologically. Most Indonesian dairy cattle are Friesian Holstein (FH), imported from European nations with a temperate environment with low temperatures in the range of 5°C–25°C. Indonesia has a tropical climate with a high ambient temperature that can reach 34°C during the day and the local relative humidity varies between 70% and 90%. Temperature and humidity are two microenvironment factors that may impact the production and heat release in FH cattle. More than 98% of the entire dairy cattle population in Indonesia is found on Java Island. On Java Island, there are between 534.22 and 543.55 thousand heads of cattle, while the dairy cattle population outside Java Island is just 6.59 thousand heads of cattle. The milk output climbs by an average of 3.34% per year, or approximately 909.64 thousand tons and the average annual growth in whole milk consumption was 0.19 L/capita. Indonesian cow milk output has been unable to keep pace with the country’s increasing demand. This study aimed to review the strategies to mitigate heat stress in FH dairy cattle in Indonesia. Keywords: dairy cattle, heat stress, Indonesia, tropical country.
Background and Aim: The quality of frozen bull sperm after thawing is influenced by the primary diluent and antioxidant. This meta-analysis was conducted to determine the effect of supplementing L-cysteine and its group analogs on the quality of frozen bull sperm. Materials and Methods: A total of 22 articles obtained from Google Scholar and Scopus were integrated into metadata. The effects of adding L-cysteine and its analogs (e.g., cysteine HCl and N-acetyl-L-cysteine), both of which are known as L-cysteine, were evaluated in this meta-analysis. The following parameters were examined: Abnormality, acrosome damage, acrosomal integrity, DNA damage, DNA integrity, malondialdehyde (MDA) content, plasma membrane integrity, pregnancy rate, progressive motility, sperm viability, and total motility. Data were analyzed using the mixed model methodology, with L-cysteine dosage as a fixed effect and different studies as random effects. Results: L-cysteine supplementation significantly increased the total motility (p < 0.05) and MDA content of semen, following a linear pattern. Progressive motility, acrosomal integrity, and plasma membrane integrity were significantly increased, showing a quadratic pattern (p < 0.05). Abnormality and acrosome damage were significantly decreased (p < 0.05), following a quadratic and linear pattern, respectively. Other parameters remained unaffected by L-cysteine supplementation. L-cysteine and cysteine HCl significantly inhibited (p = 0.001) acrosome damage in thawed frozen sperm compared with control sperm. Conclusion: Supplementing L-cysteine and its analog groups are recommended for freezing bull semen as it generally improves sperm quality.
A constant supply of feed is critical for the sustainability of cattle and buffalo ranching. Therefore, this study aims to collect data on the availability of feed made from agricultural waste to aid in the expansion of cattle and buffalo populations in the West Aceh District. It was conducted in September and October 2021 at Aceh Barat District. The secondary data were collected through the website of the Central Bureau of Statistics Indonesia and West Aceh. Furthermore, feed potential data from agricultural waste were collected from West Aceh District, cattle, and buffalo population data from the 2011 collection for buffalos, beef, and dairy cattle (PSPK). Also, cattle and buffalo population data were collected from the 2016 Central Bureau of Statistics (BPS). The data collected were then analyzed descriptively. The results showed that the West Aceh District provides only digested dry weight (BKC) from agricultural waste to meet 74.27% of the livestock population’s total BKC requirements. Additionally, only Woyla and West Woyla Sub-districts meet feed needs from agricultural waste, with 135.12% and 266.42%, respectively, based on livestock populations. Conclusively, the growth of the livestock population will result in a decrease in agricultural waste’s carrying capacity as animal feed.
