Schleid.,) as a natural antioxidant <p><strong>Objective</strong>: Lipid oxidation of meat is one of the most important factors affecting shelf life and is one of the decisive factors in the consumer's purchase decision of the product. Therefore, information related to lipid oxidation using rosemary (<em>Salvia rosmarinus </em>(L.) Schleid.) as a natural antioxidant is described and analyzed.</p> <p><strong>Design/methodology/approach: </strong>Mechanisms of oxidation were explored and described, as well as the alternatives to stop this process and different methodologies to measure antioxidant activity and innovative alternatives that are currently being investigated.</p> <p><strong>Results:</strong> Appling antioxidants is one of the most widely used methods to counteract the oxidation process in meat. Currently, using herbs and spices has gained great acceptance, as in the case of rosemary. Its usage obtained satisfactory results for inhibiting and delaying lipid oxidation.</p> <p><strong>Limitations of the study/implications:</strong> Using rosemary may have some drawbacks such as incorporating a strong flavor to the meat and the effects that its active compounds may have when exposed to oxygen, heat and humidity. Therefore, it is necessary to research for alternatives that will allow better preservation and availability of its compounds.</p> <p><strong>Findings/conclusions:</strong> Nanoencapsulation of rosemary may be an alternative to the drawbacks of its use, working as a protective barrier for improved performance and improving food safety. However, this innovation is just being explored and is therefore not possible to have a certainty of success when using these new technological alternatives.</p> Veronica Resendiz-Cruz, J.

However, it is in the fall, the reproductive season of seasonal sheep, when their behavior is much more complex and complete. It begins with smelling the external genitals of the female, goes through the flehmen response and ends with mating, intromission and ejaculation. It is necessary to consider the anatomical and physiological aspects of the ram and its meticulous management to avoid reproductive failures in the flock. Frequently, the rams are less important for the flock’s handler during the season of reproductive rest. Monitoring their diet and parasite and disease control is necessary to keep them apt for reproduction. The evaluation of the reproductive aptitude of the ram before mating is convenient and can be planned as part of its management; and once mating begins, considering the adequate proportion of rams/females, in addition to monitoring their performance during this event.</p> <p><strong>Study Limitations/Implications:</strong> To consider that the ram shows a good capacity for mating, capacity for service, libido, quality of semen, since it is responsible for a proportion of lamb production.</p> <p><strong>Findings/Conclusions:</strong> Reproduction in sheep is regulated by the photoperiod, genetic potential, nutritional status, health status and other factors, which are important both in the ram and in the female. Some sheep breeds have potential of prolificacy; a good reproductive management of the ram can influence these factors and increase the reproduction rate in the flocks.</p> Francisco Cruz-Espinoza Jaime Gallegos-Sánchez Tamara Alejandra Mendieta-Galán Christofer I.

Postpartum anestrus occurs mainly as a result of suckling, since the latter inhibits the pulsating secretion of the gonadotropin-releasing hormone (GnRH) and the luteinizing hormone (LH). The exact path of this inhibition is unknown, although it seems that endogenous opioid peptides and kisspeptin are intermediaries. Controlled suckling and the male effect are management strategies that improve the reproductive behavior of postpartum ewes. Kisspeptin regulates the influence of the male effect through the secretion of GnRH/LH.</p> <p><strong>Study Limitations/Implications:</strong> To understand the impacts of suckling and the male effect on the duration of postpartum anestrus, as well as the participation of kisspeptin in the regulation of both effects, will allow designing management strategies to improve the reproductive efficiency of the ewes.</p> <p><strong>Findings/Conclusions</strong>: Controlled suckling and the male effect reduce postpartum anestrus and improve the reproductive behavior of the ewes; advancing knowledge of the kisspeptin effect could improve the effectiveness of both techniques.</p> José M.

Presently there is a large variety of biotechnologies that can be applied in the production units, to potentiate the reproductive activity of the goat.</p> <p><strong>Study Limitations/Implications</strong>: The lack of knowledge and the lack of consulting and technical training limit the productive and reproductive potential of goat breeding in Mexico.</p> <p><strong>Findings/Conclusions</strong>: Knowledge of the reproductive physiology of the goat and understanding of the means available to manipulate it guarantees its reproduction at the time and in the conditions desired by the producer and the market</p> J.

Through the dissemination of audiovisual capsules on social<br />networks, places with tourist potential were made known and together with the implementation of the offer of<br />biodegradable co-products, it was demonstrated that plantain leaf can be used alternately.<br /><strong>Study Limitations/Implications:</strong> Due to the SARS-CoV-2 (COVID-19) coronavirus pandemic, the dissemination of our findings and products were restricted.<br /><strong>Conclusions</strong>: Novel biodegradable products can be manufactured from plantain leaves, which created a<br />special interest of local tourists to visit Monte Salas and enjoy the agrosystemic landscape.</p> Esthefania Bonilla-Gutiérrez Fernando Carlos Gómez-Merino, Libia Iris I.
