Mitigation of NH emission from pig house using a rice husk biochar column and fertilizer potential of collected biochar.

NH emissions have significant implications for ecosystems and human health. Pig houses are important sources of NH emissions. This study aimed to evaluate the NH adsorption capacity of rice husk biochar (RHB), its effectiveness in mitigating NH emission from pig house using a RHB column, and the fertilizer potential of the collected RHB for maize growth.

Genetic Diversity and Conservation Priority of Korean Chicken Breeds Using Single-Nucleotide Polymorphism Markers.

Maintaining genetic diversity is vital for biodiversity and livestock sustainability, with monitoring serving as a prerequisite for conservation strategies. As an initial step for developing future strategies, we analysed the genetic diversity and conservation priorities of 16 chicken breeds managed by a government institute in this study. The breeds were classified as native or locally adapted per FAO definitions and grouped by origin (i.

Mitochondrial Genomes of Korean Native Black Goats Reveal Shared Phylogeographic Patterns and Demographic History.

This study explores the phylogeny of Korean native black goats through analysis of their complete mitochondrial DNA. The National Institute of Animal Science has gathered genetic material on purebred goats from isolated regions such as Tongyeong, Dangjin, and Jangsu, and is actively breeding them on a national level. These populations, however, are small and exhibit high inbreeding rates, highlighting the urgent need to preserve genetic diversity.

Effects of Short-Term Differences in Concentrate Feeding on the Recovery of In Vivo Embryos in Hanwoo Donor Cows through Superovulation Treatment.

Superovulation is a technique used to increase the number of oocytes released for fertilization. This study investigated the effects of short-term differences in concentrate feed intake on in vivo embryo production through superovulation in indigenous Korean (Hanwoo) cows. The cows were given fresh water and hay ad libitum and randomly divided into three groups (control (CON, n = 9): 2.
