Kebumen Ongole Grade cattle represent a distinctive local breed of beef cattle in Indonesia known for their adaptability to tropical climates and low-input farming methods. These cattle, which are descended from Indian Ongole cattle, have a long history of development. While these cattle have many similarities to their ancestors, they have evolved unique features and performance traits, particularly in the Kebumen region. Despite their recognized value, the population has declined as a result of crossbreeding with other cattle breeds and uncont...

Subclinical mastitis (SCM) remains a significant challenge in buffalo farming across Asia, impacting both animal welfare and economic productivity. In this review, we assessed the status, pathogenesis, risk factors, antimicrobial resistance (AMR) and therapeutic measures associated with SCM in buffalo populations. This study revealed a pooled prevalence of SCM in Asia at 41.51% (2,513/6,054; 95% CI: 40.26–42.76) with considerable variation observed across different regions. Notably, Turkey exhibited the highest pooled prevalence at 61.1% (95%...

Prospects of feed additive incorporation in laying hen diets: a narrative review of principal biological effects and recent developments

Elijah Ogola Oketch, Jung Min Heo

J Anim Sci Technol 2026;68(1):50-71.
https://doi.org/10.5187/jast.2500369

Selected feed additives (probiotics, prebiotics, synbiotics, postbiotics, phytogenics, feed enzymes, and organic acids) are reviewed for reported biological responses, and some recent developments when incorporated into laying hen diets. Several feed enzymes (phytase, carbohydrase, protease, and multi-enzymes) have been adopted to improve the nutritive quality of feedstuffs by mitigating inherent digestive function inefficiencies, complementing endogenous enzyme activity, and cleaving anti-nutritional factors abundant in vegetable-based poultry...

https://doi.org/10.5187/jast.2024.e104

Mohair, an important source of fiber, is only obtained from Angora goats. The important characteristics that determine the economic value of mohair are fiber diameter and quantity. In countries where mohair is produced, efforts are made to improve these characteristics. It is stated that hair follicle characteristics and/or genetic regulation mechanisms that form animal fibers directly affect fiber production and quality. In this study, it was aimed to determine the genes affecting mohair development in two varieties of Angora goat and the mole...

https://doi.org/10.5187/jast.2024.e108

Glucose-regulated protein 78 (GRP78), which belongs to the heat shock protein 70 family, is a chaperone essential for maintaining cellular balance in the endoplasmic reticulum. It acts as a receptor on the cell surface, affecting cell growth and survival. Recent research has emphasized the involvement of GRP78 in protein folding, endoplasmic reticulum stress signaling, and cancer cell proliferation and highlighted its presence on sperm cells, where it contributes to spermatogenesis and sperm capacitation. Despite these findings, the association...

This study was conducted to determine the optimal standard ileal digestible (SID) arginine (Arg) to SID lysine (Lys) ratio in broilers under cyclic heat stress. Additionally this study tested whether citrulline (Cit) can replace Arg under cyclic heat stress, based on the report that a large amount of Arg is metabolized in the liver while Cit can by-pass metabolism in the liver. A total of 360, one-day-old Arbor Acres broiler chickens with initial body weight of 34.50 ± 0.87 g were placed in 24 pens. The 24 pens were randomly assigned to four...

J Anim Sci Technol 2026;68(1):181-196.
https://doi.org/10.5187/jast.2500128

Weaned piglets are highly susceptible to infections caused by enterotoxigenic Escherichia coli (ETEC), and phytobiotic supplementation has been explored as a potential strategy to prevent or mitigate such infections during the weaning period. However, comprehensive studies on the specific effects of phytobiotics on pig gut health and microbiota composition remains limited.

J Anim Sci Technol 2026;68(1):219-235.
https://doi.org/10.5187/jast.2024.e103

Respiratory diseases have been recognized as a significant cause of reduced livestock productivity since 1995. Respiratory diseases in the swine industry caused by both biological and non-biological factors are collectively referred to as porcine respiratory disease complex (PRDC). However, there is a lack of eco-friendly anti-inflammatory drugs (AIDs) that can effectively control lung inflammation caused by PRDC. P2Y purinoreceptor 14 (P2Y14) has been identified as a key regulator of macrophage inflammatory responses; however, its regulatory r...
