Variabilidad morfoestructural, zoométrica y faneróptica de machos cabríos locales del norte de México

Abstract: El objetivo fue caracterizar la variabilidad morfoestructural, zoométrica y faneróptica de machos cabríos locales del norte de México. Se utilizaron 46 machos que se manejan como sementales que cubren aproximadamente a 1670 hembras en 4 municipios de Coahuila, México. Se asignaron a tres grupos [(1) Jóvenes (n = 9); (2) Adultos jóvenes (n = 20) y (3) Adultos maduros (n = 17)]. Se registraron 15 variables cualitativas con 50 variantes y 20 variables cuantitativas. Se encontró un fenotipo heterogéneo, con animal… Show more

“…The results found are similar to those reported by Sheriff et al (2021), for Arab and Oromo kids regarding morphostructural characteristics. Likewise, the observed diversity is considered as "Mosaico Lagunero", which is an undefined phenotype, characteristic in crossbred animals (Amills et al, 2017;Moyao-Ariza et al, 2022). Regarding morphostructural composition due to coat color (Table 2), the highest values (p < 0.05) were found in dark kids for PV, LCue, ACue, CPe and PFl; while for light kid differences (p < 0.05) were only found in LO.…”

“…The PV was taken fasting with an electronic hanging scale with a capacity of 45 kg±5 g (Metrology, Nuevo Leon, Mexico). The zoomometric measurements were (Figure 1): face length (LCa-1), face width (ACa-2), ear length (LO-3), ear width (AO-4), neck length (LCu-5), neck width (Acu-6), body length (LCor-7), height at withers (ACruz-8), chest circumference (CPe-9), barrel circumference (CBa-10), flank depth (PFl-11), sacrolumbar height (ASL-12), leg length (LPi-13), shank circumference (PCn-14) (Moyao-Ariza et al , 2022). The magnitude of the development of the animals in the different age groups was analyzed, which means the development of each anatomical part of the animal was quantified, since they do not have the same growth speed, therefore, this analysis is proposed to identify critical growth points in developing kids.…”

“…Some reports indicate that, in agro-pastoral production systems, such as the ones described in places from Africa and Mexico, the selection of bucks is made by appearance, with a predilection to spotted or mottled animals and flat colored [88][89][90] (Figure 1). In addition, several factors of social nature have a principal role in the definition of selection criteria.…”

“…Some efforts have been made in northern Mexico [94] that have shed light on a possible effect of coat and skin color on local goats' longevity and phenotypic differentiation. Nevertheless, these data need to be corroborated and studied in more detail, and, in the case that results are verified, this would be advantageous as an indirect selection criterion, since greater ease of recognition of desirable animals and greater longevity are directly related to a longer productive life [90,94]. The animal's color is one of the most important means of identification between and within herds [64].…”

“…In this sense, the coat color in goats (Capra hircus) is known as a genetic adaptation propelled by environmental conditions [10], therefore, the changes that are perceived in the climate suggest a deeper interaction between traits such as skin and hair color with productive and reproductive aspects and the general behavior of the animals [7]. However, the studies that consider these characteristics and their effect in both productive and reproductive traits in local goats are scarce, particularly in Mexico, since all these studies are merely descriptive [9,14,15]. Therefore, the objectives of this research were to evaluate the effects of the number and diversity of colors; coat pattern, and skin color of goats on longevity; ethnological and functional indices in local goats from Comarca Lagunera in Northern Mexico.…”
