Novel gene-editing (GE) technologies provide promising opportunities to increase livestock productivity and tackle several global production sustainability food security challenges. However, these technologies, as with previous genetic modification in production, are very likely generate social controversy opposition toward their use the meat industry. Here, we explored public attitudes consumption predisposition gene-edited products potential added benefits farming. Our results show that societal perception currently comes a package, where of technology acts an extrinsic cue quality, is used make range inferences about all quality facets at once. Although consumers anti-GE attitudinal positions generally were not sensitive price discounts or benefits, increased most moderate pro-GE consumers, related animal welfare had larger effects than those relating environment human health issues.

Genome-editing opportunities to enhance cattle productivity in the tropics

CABI Agriculture and Bioscience, Год журнала: 2022, Номер 3(1)

Опубликована: Фев. 14, 2022

Abstract The livestock performance in tropical regions has been limited by environmental conditions that causes heat stress and favors the development of parasites diseases, impairing animal health. Heat disturbs homeostasis affects production fertility, with negative impacts on meat milk quality. Flies ticks proliferate easily under hot-humid weather, which makes difficult control their population, resulting an increased parasitism. Tropical pastures usually have high dry matter production, but it is challenging to keep quality different throughout year, constraining performance. Several strategies adopted attempt overcome such hurdles regions, definitive solutions are yet be implemented. In last 20 years, biotechnologies, as vitro embryo genomic selection, played important role cattle countries. Genome editing (GnEd) novel tool toolbox for production. GnEd selection offers opportunity boost genetic gain breeding programs fewer generations. It can applied disease resistance, parasite improve pasture tolerance biotic abiotic stresses, favoring health nutrition. Moreover, there a perspective use methane emission genes methanogens present rumen. Although already some traits, studies still required identification candidate animals, pastures, parasites, microorganisms targeted gene order offer robust contribution improvement hot regions. Some examples presented this review, focusing new perspectives using increase challenges environments.

Sustainable Food Production: The Contribution of Genome Editing in Livestock

Sustainability, Год журнала: 2021, Номер 13(12), С. 6788 - 6788

Опубликована: Июнь 16, 2021

The growing demand for animal source foods to feed people has been pushing the livestock industry increase productivity, a tendency that will continue throughout this century. challenge coming years is food supply ensure equity in access high quality food, while maintaining global sustainability including combating climate change, avoiding deforestation, and conserving biodiversity, as well ensuring health welfare. question is, how do we produce more with less? Classical methods enhance productivity based on improvement of health, nutrition, genetics, reproductive technologies management have made important contributions; however, not going be enough thus disruptive approaches are required. Genome editing CRISPR may powerful contributor transformation. This article focused scope perspectives application technology, which includes improving production traits, enhancing welfare through adaptation resilience, conferring resistance infectious diseases, suppressing pests invasive species threaten livestock. main advantages concerns should overcome by science, policy discussed aim technology can make real contribution our collective future. review part special issue “Genome Editing Animal Systems Support Sustainable Farming Pest Control”.

Review: Development, adoption, and impact of assisted reproduction in domestic buffaloes

animal, Год журнала: 2023, Номер 17, С. 100764 - 100764

Опубликована: Май 1, 2023

The domestic buffalo (Bubalus bubalis), also known as water buffalo, comprises two sub-species the River (B. bubalis ssp. bubalis; 50 chromosomes) and Swamp (ssp. carabanensis; 48 chromosomes). Domestic buffaloes are a globally significant livestock species. In South Asia, is primary source of milk meat has very important role in food security. supports high-value, differentiated production Europe Americas. an draft animal Southeast Asia East Asia. growing importance requires that they undergo accelerated rate genetic gain for efficiency production, product quality, sustainability. This will involve increased use assisted reproduction. initial application reproductive technology had variable success it relied on adoption procedures developed cattle. included artificial insemination (AI), sperm cryopreservation, embryo technologies such cloning vitro (IVEP). Reproductive been progressively refined buffaloes, today, AI IVEP comparable to Ovarian follicular superstimulation (superovulation) combined with vivo results low recovery limited practical application. contribution elite female future improvement therefore rely mainly oocyte pickup IVEP. include from females before puberty reduce generation intervals. review provides first time clear chronology development, adoption, impact, reproduction buffaloes.

Effects of Rumen-Protected L-Tryptophan Supplementation on Productivity, Physiological Indicators, Blood Profiles, and Heat Shock Protein Gene Expression in Lactating Holstein Cows under Heat Stress Conditions

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(2), С. 1217 - 1217

In this study, we examined the effects of rumen-protected L-tryptophan supplementation on productivity and physiological metabolic indicators in lactating Holstein cows under heat stress conditions. The study involved eight early (days milk = 40 ± 9 days; yield 30 1.5 kg/day; parity 1.09 0.05, p < 0.05), four per experiment, with environmentally controlled chambers. each two distinct conditions were created: a low-temperature low-humidity (LTLH) condition at 25 °C 35-50% humidity high-temperature high-humidity (HTHH) 31 80-95% humidity. During adaptation phase, subjected to LTLH HTHH for 3 days. This was followed by 4-day phase then 7-day stress, which complemented (ACT). findings revealed that ACT increased dry matter intake as well protein decreased water intake, heart rate, rectal temperature group (p 0.05). For plateletcrit (PCT, 0.0600), eosinophil percentage (EOS, 0.0880) showed tendency be lower, while monocyte (MONO) large unstained cells (LUC) amounts both groups Albumin glucose levels lower gene expressions shock proteins 70 90 peripheral blood mononuclear higher (HTHH, These results suggest improved productivity, indicators, characteristics, expression heat-stress particular, objectively relieved these animals, suggesting has potential viable solution combating heat-stress-induced cattle dairy farming.
