Molecular strategies to enhance the keratinase gene expression and its potential implications in poultry feed industry Poul. Sci. (IF 4.4) Pub Date : 2024-03-05 Muhammad Saeed, Mingchen Yan, Zhong Ni, Nazar Hussain, Huayou Chen
The tons of keratin waste are produced by the poultry and meat industry which is an insoluble and protein-rich material found in hair, feathers, wool, and some epidermal wastes. These waste products could be degraded and recycled to recover protein, which can save our environment. One of the potential strategy to achieve this target is use of microbial biotreatment which is more convenient, cost-effective

Investigating antibiotic free feed additives for growth promotion in poultry: effects on performance and microbiota Poul. Sci. (IF 4.4) Pub Date : 2024-03-04 Ana Fonseca, Sophia Kenney, Emily Van Syoc, Stephanie Bierly, Francisco Dini-Andreote, Justin Silverman, John Boney, Erika Ganda
The poultry industry is evolving towards antibiotic-free production to meet market demands and decelerate the increasing spread of the antimicrobial resistance. The growing need for antibiotic free products has challenged producers to decrease or completely stop using antimicrobials as feed supplements in broiler diet to improve feed efficiency, growth rate, and intestinal health. Natural feed additives

Signaling pathways and regulatory networks in quail skeletal muscle development: insights from whole transcriptome sequencing Poul. Sci. (IF 4.4) Pub Date : 2024-03-01 Wentao Zhang, Jing Liu, Ya'nan Zhou, Shuibing Liu, Jintao Wu, Hongxia Jiang, Jiguo Xu, Huirong Mao, Sanfeng Liu, Biao Chen
Quail, as an advantageous avian model organism due to its compact size and short reproductive cycle, holds substantial potential for enhancing our understanding of skeletal muscle development. The quantity of skeletal muscle represents a vital economic trait in poultry production. Unraveling the molecular mechanisms governing quail skeletal muscle development is of paramount importance for optimizing

Ileal phosphorus digestibility of soybean meal for broiler chickens remains consistent across institutions in a collaborative study regardless of non-phytate phosphorus concentration in the pre-experimental starter diet Poul. Sci. (IF 4.4) Pub Date : 2024-02-29 V.S. Haetinger, J.Y. Sung, S.A. Adedokun, W.A. Dozier, C.M. Parsons, M. Rodehutscord, O. Adeola
The same experimental protocol was used in 4 institutions to evaluate the impact of non-phytate phosphorus () concentration in the starter diet on regression method-derived ileal P digestibility of soybean meal () during the subsequent grower phase. A total of 1,536 Ross 308 male broiler chickens on d 0 post hatching were allotted to 2 pre-experimental starter diets that contained 3.5 or 4.5 g nPP/kg

Effects of dietary Artemisia annua supplementation on growth performance, antioxidant capacity, immune function, and gut microbiota of geese Poul. Sci. (IF 4.4) Pub Date : 2024-02-28 Yizhe Cui, Xinyang Leng, Yujie Zhao, Yu Zhao, Qiuju Wang
This experiment aimed to study the effect of 1% added to the diet on growth performance, antioxidant capacity, immunity and intestinal morphology, and gut microbiota of geese. Seventy-two 35-day-old male geese () with similar body weight were selected and randomly divided into 2 groups. Each treatment group of 36 geese was divided into 6 subgroups, each having 6 male geese. The experiment lasted for

Genome-wide association studies of anserine and carnosine contents in the breast meat of Korean native chickens Poul. Sci. (IF 4.4) Pub Date : 2024-02-28 Minjun Kim, Jean P. Munyaneza, Eunjin Cho, Aera Jang, Cheorun Jo, Ki-Chang Nam, Hyo Jun Choo, Jun Heon Lee
Histidine-containing dipeptides (), such as anserine and carnosine, are enormously beneficial to human health and contribute to the meat flavor in chickens. Meat quality traits, including flavor, are polygenic traits with medium to high heritability. Polygenic traits can be improved through a better understanding of their genetic mechanisms. Genome-wide association studies () constitute an effective

Deoxynivalenol and fumonisin predispose broilers to bacterial chondronecrosis with osteomyelitis lameness Poul. Sci. (IF 4.4) Pub Date : 2024-02-28 Khawla Alharbi, Nnamdi Ekesi, Amer Hasan, Andi Asnayanti, Jundi Liu, Raj Murugesan, Shelby Ramirez, Samuel Rochell, Michael T. Kidd, Adnan Alrubaye
Bacterial chondronecrosis with osteomyelitis () lameness is the most critical animal health and welfare issue facing the broiler industry worldwide. It is estimated that 1 to 2% of bird condemnation at marketing age is caused by BCO lameness, resulting in tens of millions of dollars in annual losses. Fast-growing broilers are prone to mechanical stress that triggers bacterial translocation across epithelial

Preening cups in duck housing are associated with an increase in central dopamine activity that suggests a negative affective state Poul. Sci. (IF 4.4) Pub Date : 2024-02-28 M.M. Bergman, J.M. Schober, E.M. Oluwagbenga, D. Frey, H. Parnin, G.S. Fraley
Preening cups are a form of environmental enrichment that provides Pekin ducks a semi-open water source to express their natural behaviors. We recently observed that preening cups may increase feather pecking behaviors in ducks. Thus, we set out to determine if this form of enrichment can impact the affective state of Pekin ducks. To accomplish this goal, we evaluated the effect of preening cups on
