This behavior is mainly triggered by hormone concentration changes and their interactions with their respective receptors in the brain, particularly oxytocin. These chemical signals also influence mother–young bonding, a critical process for neonatal survival that develops during the first postpartum hours. Currently, dairy buffalo behavior during parturition has rarely been studied. For this reason, this review aims to analyze the existing scientific evidence regarding maternal behavior in water buffalo during calving. It will address the mechanisms of imprinting, maternal care, and allosuckling strategies that may influence the survival and health of calves.

The goals are to define the scope and areas of opportunity for IRT use in evaluating physiological processes and identifying potential applications in reproductive events associated with andrological traits in males and the detection of estrus and udder health in females. IRT has allowed the development of diverse perspectives regarding the comparative physiology of events like thermogenesis, peripheral blood flow, respiratory physiology, and mechanisms that reduce body temperature. The case of the river buffalo is no exception. According to the information analyzed, the temperatures of the orbital area, muzzle, and vulva have proven efficient for evaluating thermal comfort, a particularly important aspect of this species given its limited thermoregulating capacity and constant exposure to extreme temperatures. Evaluating scrotal temperature has been revealed as an appropriate tool for evaluating semen quality, while the surface temperature of the udder is useful in assessing mammary development in female buffaloes, two aspects of great zootechnical importance. In future studies, IRT will play a fundamental role in enhancing our understanding of the river buffalo's mechanisms of vascular microcirculation, with applications in productivity and behavior.

The objectives were to obtain a broader profile of this system and capture values related to buffalo breeding in that area. The study identified a group of producers with high levels of education (17 ± 1.15 years) and years of experience in agricultural systems (28.75 ± 10.81), especially with buffaloes (9 ± 1.83 years). Land tenure is private, and the average surface area of ranches is 428.75 ± 245.57 hectares, located mainly (92%) in flatlands and floodplains with an average number of animals per hectare 2.03 ± 0.69 AU/h. The area has various vegetable strata (grasses, bushes, trees). Feeding is based on the consumption of vegetable species like Camalote grass (Paspalum fasciculatum), West Indian Azuche grass (Hymenachne amplexicaulis), and Aleman grass (Echinochloa polystachya), complemented with minerals. Production units (PU) 2 and 3 add a low proportion of balanced feed. The ...

In recent years, buffalo production has been incorporated into the region, with possibilities for development in profitable and sustainable models. To study this option in depth, a broad bibliographic review was carried out focusing on the ecological characteristics of tropical zones and the physiological and productive characteristics of buffaloes. We also investigated the structure and functioning of dual-purpose systems that have worked in cattle and that can be optimized with this alternative animal species. The possibility of taking sustainable advantage of abundant forage resources in the region was detected through intensive grazing models, as well as agrosilvopastoral systems, due to the gregarious qualities of buffaloes and responding to their the...

En este artículo se analizan resultados de investigaciones que documentan la viabilidad de los sistemas de producción de búfalos de agua en un ambiente propicio y exigente como el trópico mexicano, siguiendo los preceptos de la agroecología. Se examinan los principios básicos de la agroecología aplicada a la ganadería, para identificar la interacción suelovegetación-búfalos y potenciar procesos de resiliencia. Se caracterizaron los aspectos físico-bióticos de la región tropical, en especial sus recursos forrajeros. También se estudian las características anatómicas y fisiológicas de los búfalos para prosperar en este ambiente, bajo la modalidad de doble propósito, produciendo carne y leche. Finalmente, se aportan elementos para diseñar sistemas de pastoreo intensivo, incluyendo los silvopastoriles, en ...

Celui-ci signifie l'abandon d'une forte regulation etatique et l'acceleration du processus d'internationalisation tout en affirmant un objectif d'autosuffisance nationale. Le sous-systeme tropical, qui s'est distingue jusqu'alors par sa capacite d'expansion en conditions de crise et est devenu le principal axe productif du pays, represente un espace d'observation des strategies individuelles. Pour etudier les rapports entre les dynamiques lourdes et les strategies d'adaptation, il a ete adopte une approche meso-analytique. De cette facon, trois filieres, chacune articulee autour d'un pole dominant, ont ete definies en fonction des formes de production, de coordination et, en derniere instance, de gestion de la flexibilite. La flexibilite, principale caracteristique des filieres tropicales, semble s'accentuer avec la montee des risques, les tensions creees par leur repartition et l'augmentation de la concurrence. Ainsi, a l'intervention de l'etat se substituent des strategies et des processus d'adaptation d'acteurs individuels, moyens insuffisants pour permettre une coordination correcte des filieres tropicales. Leur fonctionnement met en question l'autosuffisance

A este último se conjuga un activo dispositivo institucional, centrado en capacitación, transferencia de tocologías sencillas y, en especial, la dotación de centros de acopio donde se aglutinan los ganaderos. También ha influido la inclusión de nuevas formas contractuales, basadas en la comercialización de leche fría y en estrictas normas de calidad controladas por las agroindustrias. Este análisis se concreta en un estudio comparativo entre dos organizaciones lecheras, que permiten concluir sobre un notable proceso de modernización (más) incluyente y sostenible del sistema lechero hidrocálido

The paper analyzes the new contractual relations on the basis of three main aspects: a) the new quality standards for milk implemented by stockbreeders without being given adequate compensation, b) the management of seasonal production surpluses, in which stockbreeders have also assumed greater risks and c) the actual prices offered to producers and consumers, summarized in the fact that improvements in the quality and efficiency of the chain are not reflected in benefits for these agents but instead remain at the processing and distribution stages. It concludes that restructuring translates into a new hegemonic position of the agro-industries-without sharing risks and benefits-thereby jeopardizing the sustainable development of this localized production chain.

La presente obra fue generada en el marco de la interdisciplina por especialistas en el tema de los Sistemas Nacionales Lecheros. Sin embargo, se provilegio el analisis desde las Ciencias Sociales, dado que han estado muy poco vinculadas al estudio de la lecheria y de los actores sociales que participan en ella, a pesar de que en este ambito se han identificado los principales obstaculos para su desarrollo. Ademas se observa el surgimiento de nuevos agentes sociales y formas de actuar de parte de los sectores involucrados. El resultado se enmarca en la consideracion de que en los tres paises la actividad lechera desempena un papel estrategico en la economia nacional en terminos de seguridad alimentaria, empleo rural, articulacion de sectores productivos y comercio exterior. Los tres SNL presentan diferentes problematicas. Canada y Estados Unidos cuentan con una produccion excedentaria y Mexico se distingue por ser un pais deficitario, pero con potencialidades de desarrollo.

Para ello se analizan las nuevas relaciones contractuales a partir de tres aspectos fundamentales: a) las nuevas normas de calidad de la leche incorporadas por los ganaderos, pero sin que por ello reciban una contribución adecuada; b) la gestión de los excedentes estacionales en la producción, en la que también los ganaderos han asumido los mayores riesgos, y c) los precios reales ofrecidos al productor y al consumidor, que sintetizan que las mejoras de la calidad y de la eficiencia de la cadena no se reflejan en beneficios para estos agentes, sino que se queda en las fases de procesamiento y distribución. Se concluye que la reestructuración se traduce en una nueva posición hegemónica d...
