This study investigated the effects of inorganic and organic minerals on physiological responses, oxidative stress reduction, and rumen microbiota in Holstein bull calves (123.81 ± 9.76 kg; 5 months old) during short-term heat stress (HS) and recovery periods. Eight Holstein calves were randomly assigned to four treatment groups: no mineral supplementation (Con), inorganic minerals (IM), organic minerals

Gut microbiota intervention attenuates thermogenesis in broilers exposed to high temperature through modulation of the hypothalamic 5-HT pathway J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-21 Sheng Li, Xiaoqing Li, Kai Wang, Yansen Li, Kentaro Nagaoka, Chunmei Li
Broilers have a robust metabolism and high body temperature, which make them less tolerant to high-temperature (HT) environments and more susceptible to challenges from elevated temperatures. Gut microbes, functioning as symbionts within the host, possess the capacity to significantly regulate the physiological functions and environmental adaptability of the host. This study aims to investigate the

Enterogenic Stenotrophomonas maltophilia migrates to the mammary gland to induce mastitis by activating the calcium-ROS-AMPK-mTOR-autophagy pathway J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-20 Zhaoqi He, Caijun Zhao, Yuhong He, Zhuoyu Liu, Guyue Fan, Kun Zhu, Yiqi Wang, Naisheng Zhang, Yunhe Fu, Xiaoyu Hu
Mastitis is an inflammatory disease of the mammary gland that has serious economic impacts on the dairy industry and endangers food safety. Our previous study found that the body has a gut/rumen-mammary gland axis and that disturbance of the gut/rumen microbiota could result in ‘gastroenterogenic mastitis’. However, the mechanism has not been fully clarified. Recently, we found that long-term feeding

Gut microbiota affects the estrus return of sows by regulating the metabolism of sex steroid hormones J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-20 Min Liu, Jia Zhang, Yunyan Zhou, Shuqi Xiong, Mengqing Zhou, Lin Wu, Qin Liu, Zhe Chen, Hui Jiang, Jiawen Yang, Yuxin Liu, Yaxiang Wang, Congying Chen, Lusheng Huang
Sex hormones play important roles in the estrus return of post-weaning sows. Previous studies have demonstrated a complex and bi-directional regulation between sex hormones and gut microbiota. However, the extent to which the gut microbiota affects estrus return of post-weaning sows is largely unknown. In this study, we first screened 207 fecal samples from well-phenotyped sows by 16S rRNA gene sequencing

Amino acid and mineral digestibility, bone ash, and plasma inositol is increased by including microbial phytase in diets for growing pigs J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-10 Liz Vanessa Lagos, Mike Richard Bedford, Hans Henrik Stein
The effect of microbial phytase on amino acid and energy digestibility is not consistent in pigs, which may be related to the phytase dosage or the adaptation length to the diet. Therefore, an experiment was conducted to test the hypotheses that increasing dietary phytase after an 18-day adaptation period: 1) increases nutrient and energy digestibility; 2) increases plasma P, plasma inositol, and bone

Single-cell transcriptomic atlas of goat ovarian aging J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-06 Dejun Xu, Shuaifei Song, Fuguo Wang, Yawen Li, Ziyuan Li, Hui Yao, Yongju Zhao, Zhongquan Zhao
The ovaries are one of the first organs that undergo degenerative changes earlier in the aging process, and ovarian aging is shown by a decrease in the number and quality of oocytes. However, little is known about the molecular mechanisms of female age-related fertility decline in different types of ovarian cells during aging, especially in goats. Therefore, the aim of this study was to reveal the

miR-423 sponged by lncRNA NORHA inhibits granulosa cell apoptosis J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-05 Yuqi Li, Zhuofan Zhang, Siqi Wang, Xing Du, Qifa Li
Atresia and degeneration, a follicular developmental fate that reduces female fertility and is triggered by granulosa cell (GC) apoptosis, have been induced by dozens of miRNAs. Here, we report a miRNA, miR-423, that inhibits the initiation of follicular atresia (FA), and early apoptosis of GCs. We showed that miR-423 was down-regulated during sow FA, and its levels in follicles were negatively correlated

Does the provision of live black soldier fly and yellow mealworm larvae improve Muscovy duck welfare? J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-04 Marta Gariglio, Sihem Dabbou, Manuela Renna, Ilaria Biasato, Sara Bellezza Oddon, Marco Meneguz, Raul Daniel Miazzo, Stefania Bergagna, Elena Colombino, Elisabetta Macchi, Achille Schiavone
The provision of environmental enrichments to Muscovy ducks could reduce the expression of the aggressive behaviors. The aim of the present study was to evaluate the effects of black soldier fly (BSF) and yellow mealworm (YM) live larva provision on Muscovy duck performance, excreta corticosterone metabolites (ECM), behavior, and blood parameters. A total of 126 3-day-old female Muscovy ducklings were

Improving the nutritional values of yellow mealworm Tenebrio molitor (Coleoptera: Tenebrionidae) larvae as an animal feed ingredient: a review J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-03 Linggawastu Syahrulawal, Magnhild Oust Torske, Rumakanta Sapkota, Geir Næss, Prabhat Khanal
Yellow mealworm larvae (YML; Tenebrio molitor) are considered as a valuable insect species for animal feed due to their high nutritional values and ability to grow under different substrates and rearing conditions. Advances in the understanding of entomophagy and animal nutrition over the past decades have propelled research areas toward testing multiple aspects of YML to exploit them better as animal

Anti-methanogenic potential of seaweeds and seaweed-derived compounds in ruminant feed: current perspectives, risks and future prospects J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-02 Ailbhe McGurrin, Julie Maguire, Brijesh K. Tiwari, Marco Garcia-Vaquero
With methane emissions from ruminant agriculture contributing 17% of total methane emissions worldwide, there is increasing urgency to develop strategies to reduce greenhouse gas emissions in this sector. One of the proposed strategies is ruminant feed intervention studies focused on the inclusion of anti-methanogenic compounds which are those capable of interacting with the rumen microbiome, reducing

Enhancement of porcine in vitro embryonic development through luteolin-mediated activation of the Nrf2/Keap1 signaling pathway J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-12-01 Se-Been Jeon, Pil-Soo Jeong, Min Ju Kim, Hyo-Gu Kang, Bong-Seok Song, Sun-Uk Kim, Seong-Keun Cho, Bo-Woong Sim
Oxidative stress, caused by an imbalance in the production and elimination of intracellular reactive oxygen species (ROS), has been recognized for its detrimental effects on mammalian embryonic development. Luteolin (Lut) has been documented for its protective effects against oxidative stress in various studies. However, its specific role in embryonic development remains unexplored. This study aims

Insights into genetic diversity and phenotypic variations in domestic geese through comprehensive population and pan-genome analysis J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-11-24 Guangliang Gao, Hongmei Zhang, Jiangping Ni, Xianzhi Zhao, Keshan Zhang, Jian Wang, Xiangdong Kong, Qigui Wang
Domestic goose breeds are descended from either the Swan goose (Anser cygnoides) or the Greylag goose (Anser anser), exhibiting variations in body size, reproductive performance, egg production, feather color, and other phenotypic traits. Constructing a pan-genome facilitates a thorough identification of genetic variations, thereby deepening our comprehension of the molecular mechanisms underlying
