El objetivo del este trabajo fue comprobar la influencia del sistema de cría de los cabritos (diferentes sistemas de alimentación de las madres y lactoreemplazante) sobre la calidad de carne y en la correlación entre el contenido de retinol de la grasa y estos parámetros de calidad de carne. Se utilizaron 55 cabritos machos de raza Payoya divididos en cuatro grupos, uno alimentado con lactoreemplazante (LA) y tres de lactancia natural con madres con diferente manejo de alimentación: pastoreo de montaña (PM), pastoreo en pradera cultivada (PC) y estabuladas con ración mixta total (RMT). Los cabritos se sacrificaron al alcanzar los 8 kg de peso vivo, alrededor del mes de vida. Se midieron la concentración de retinol en la grasa intermuscular, el pH, composición proximal (CP), color y textura (TPA) en el longissimus thoracis y lumborum. Los cabritos PC proporcionaron una carne con menor pH, mayor luminosidad (L*), menor índice de rojo (a*) y mayor índice de amarillo (b*) y tono (h°) que el resto. Los animales PC y RMT alcanzaron en menor tiempo el peso de sacrificio y su carne se diferenció de la de los cabritos PM y LA por el contenido de retinol, composición proximal y textura. Se comprobó que no es el tipo de lactancia (natural o lactoreemplazante) lo que determina las diferencias entre grupos sino el manejo de la alimentación de las cabras.

Abstract

The objective of this study was to verify the influence of the rearing system of the kid goats (different feeding systems of the mothers and milk replacer) on the quality of meat and the correlation between the retinol content of the fat and these quality parameters of meat. Fifty-five Payoya breed male kids were used, divided into four groups: one group fed milk replacer (LA) and three groups fed natural lactation with different feeding managements of the goats: mountain grazing (PM), cultivated pasture grazing (PC) and stabled goats with total mixed ration (RMT). The kids were slaughtered when they reached 8 kg of live weight, around one month old. Retinol concentration in intermuscular fat, pH, proximal composition (CP), color and texture (TPA) were measured in longissimus thoracis and lumborum. The PC kids provided meat with a lower pH, higher luminosity (L*), lower red index (a*) and higher yellow index (b*) and hue (h degrees) than the rest. PC and RMT animals reached slaughter weight earlier and their meat differed from that of PM and LA kids due to retinol content, proximal composition and texture. It was found that it is not the type of lactation (natural or milk replacer) that determines the differences between groups but rather the feeding management of the goats.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Itea-Informacion Tecnica Economica Agraria, and although the journal is classified in the quartile Q4 (Agencia WoS (JCR)), its regional focus and specialization in Agronomy, give it significant recognition in a specific niche of scientific knowledge at an international level.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-07-16:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 6.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 11 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.5.
  • The number of mentions on the social network X (formerly Twitter): 3 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: http://hdl.handle.net/10532/6843
