Evaluation of in vitro digestibility of Aspergillus oryzae fungal biomass grown on organic residue derived-VFAs as a promising ruminant feed supplement J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-10-01 Clarisse Uwineza, Mohammadali Bouzarjomehr, Milad Parchami, Taner Sar, Mohammad J. Taherzadeh, Amir Mahboubi
As demand for high quality animal feed continues to raise, it becomes increasingly important to minimize the environmental impact of feed production. An appealing sustainable approach to provide feed fractions is to use organic residues from agro-food industry. In this regard, volatile fatty acids (VFAs) such as acetic, propionic and butyric acids, derived from bioconversion of organic residues can

A particular type of site fidelity is faithfulness to the nest site, where birds are not only reoccupying breeding territories but also reusing nests built in previous breeding seasons. Staying faithful to the nest site is believed to be an adaptive strategy, and based on the ability to predict an individual's own breeding success, a hypothesis of “win-stay:loose-switch” was proposed.

Autophagy can inhibit ovarian senescence induced by oxidative stress and regulate follicle development and atresia, but its mechanism is still unclear. Exogenous spermidine can induce autophagy and scavenge reactive oxygen species (ROS). In this experiment, oxidative stress in Sichuan white geese ovaries and follicular granulosa cells (GCs) were caused by 3-nitropropionic acid (3-NPA) and spermidine

Dietary supplementation of laminarin improves the reproductive performance of sows and the growth of suckling piglets J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-09-10 Pengguang Zhang, Guoyuan Jiang, Chenghong Ma, Yubo Wang, Enfa Yan, Linjuan He, Jianxin Guo, Xin Zhang, Jingdong Yin
Maternal nutrition is essential in keeping a highly efficient production system in the pig industry. Laminarin has been shown to improve antioxidant capacity, reduce the inflammatory response, and favor the homeostasis of intestinal microbiota. However, the effect of dietary supplementation of laminarin on the reproductive performance of sows and the growth of suckling offspring remains unknown. A

Dietary supplementation of sodium butyrate enhances lactation performance by promoting nutrient digestion and mammary gland development in dairy cows Anim. Nutr. (IF 6.3) Pub Date : 2023-09-09 Jing Zhang, Lijun Bu, Yapeng Liu, Wenjie Huo, Chengqiang Xia, Caixia Pei, Qiang Liu
This experiment was to evaluate the influence of sodium butyrate (SB) addition on milk production, ruminal fermentation, nutrient digestion, and the development and metabolism regulation of the mammary gland in dairy cows. Forty Holstein dairy cows averaging 710 ± 18.5 kg body weight, 72.8 ± 3.66 d in milk (DIM), and 41.4 ± 1.42 kg/d milk production were divided into four treatments blocked by DIM

Cranial osteology of the Brazilian dinocephalian Pampaphoneus biccai (Anteosauridae: Syodontinae) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2023-09-10 Mateus A Costa Santos, Voltaire D Paes Neto, Cesar L Schultz, Juan Cisneros, Stephanie E Pierce, Felipe L Pinheiro
The Anteosauridae (Dinocephalia) were the largest predators of Guadalupian (Middle Permian) land communities. The, thus far, only known South American anteosaurid is the medium-sized syodontine Pampaphoneus biccai. This taxon was, until now, known only by its holotype, recovered from an outcrop of the Rio do Rasto Formation, Southern Brazil. Here we describe in detail an almost complete Pampaphoneus

Comparison of methods for deriving phenotypes from incomplete observation data with an application to age at puberty in dairy cattle J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-09-09 Melissa A. Stephen, Chris R. Burke, Jennie E. Pryce, Nicole M. Steele, Peter R. Amer, Susanne Meier, Claire V. C. Phyn, Dorian J. Garrick
Many phenotypes in animal breeding are derived from incomplete measures, especially if they are challenging or expensive to measure precisely. Examples include time-dependent traits such as reproductive status, or lifespan. Incomplete measures for these traits result in phenotypes that are subject to left-, interval- and right-censoring, where phenotypes are only known to fall below an upper bound

New insights into the unfolded protein response (UPR)-anterior gradient 2 (AGR2) pathway in the regulation of intestinal barrier function in weaned piglets Anim. Nutr. (IF 6.3) Pub Date : 2023-09-09 Feng Zhang, Mengxian Chen, Xiaodan Liu, Xu Ji, Shenghe Li, Erhui Jin
Sustained dysfunction of the intestinal barrier caused by early weaning is a major factor that induces postweaning diarrhea in weaned piglets. In both healthy and diseased states, the intestinal barrier is regulated by goblet cells. Alterations in the characteristics of goblet cells are linked to intestinal barrier dysfunction and inflammatory conditions during pathogenic infections. In this review

Heat Shock Protein 27 Regulates Myogenic and Self-renewal Potential of Bovine Satellite Cells Under Heat Stress J. Anim. Sci. (IF 3.3) Pub Date : 2023-09-09 Won Seob Kim, Jayasimha R Daddam, Boon Hong Keng, Jaehwan Kim, Jongkyoo Kim
While satellite cells play a key role in the hypertrophy, repair, and regeneration of skeletal muscles, their response to heat exposure remains poorly understood, particularly in beef cattle. This study aimed to investigate the changes in the transcriptome, proteome, and proliferation capability of bovine satellite cells in response to different levels of heat stress (HS) and exposure times.

Ochratoxin A induces abnormal tryptophan metabolism in the intestine and liver to activate AMPK signaling pathway J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-09-08 Weiqing Ma, Yang Fu, Shanshan Zhu, Daiyang Xia, Shuangshuang Zhai, Deqin Xiao, Yongwen Zhu, Michel Dione, Lukuyu Ben, Lin Yang, Wence Wang
Ochratoxin A (OTA) is a mycotoxin widely present in raw food and feed materials and is mainly produced by Aspergillus ochraceus and Penicillium verrucosum. Our previous study showed that OTA principally induces liver inflammation by causing intestinal flora disorder, especially Bacteroides plebeius (B. plebeius) overgrowth. However, whether OTA or B. plebeius alteration leads to abnormal tryptophan-related

Integrins and their potential roles in mammalian pregnancy J. Anim. Sci. Biotechnol. (IF 7.0) Pub Date : 2023-09-08 Gregory A. Johnson, Robert C. Burghardt, Fuller W. Bazer, Heewon Seo, Joe W. Cain
Integrins are a highly complex family of receptors that, when expressed on the surface of cells, can mediate reciprocal cell-to-cell and cell-to-extracellular matrix (ECM) interactions leading to assembly of integrin adhesion complexes (IACs) that initiate many signaling functions both at the membrane and deeper within the cytoplasm to coordinate processes including cell adhesion, migration, proliferation

Evolutionary trade-off between innate and acquired immune defences in birds Front. Zool. (IF 2.8) Pub Date : 2023-09-08 Piotr Minias, Wei-Xuan V. -H. Peng, Kevin D. Matson
The development, maintenance, and use of immune defences are costly. Therefore, animals face trade-offs in terms of resource allocation within their immune system and between their immune system and other physiological processes. To maximize fitness, evolution may favour investment in one immunological defence or subsystem over another in a way that matches a species broader life history strategy.
