“…The morphological indices used in this study were able to characterize the phenotypic and production potential of M N lambs using the T PRI , A I , B CI "1" and B CI "2" variables, enabling the classification of breeding groups in high thoracic development, ability to produce meat, weight gain, feeding efficiency and breathing capacity, infusing greater breed rusticity and adaptability for both genetic groups (CONTRERAS et al, 2011;RAMOS, I. O. et al, 2019;SILVA-JARQUIN et al, 2019). These characteristics are in agreement with other studies which evaluated adaptability and productive potential of the M N breed, especially the red variety which has greater potential for meat production (LEITE et al, 2020;MELO et al, 2018;REZENDE et al, 2014), in addition to breaking The superiority observed in some morphometric and productive characteristics in crossbred lambs are justified by the fact that this crossbreed brought together intrinsic characteristics of the white group, meaning that we still observe the result of the heterosis process and complementarity of characteristics between genetic groups, even within the same breed. This is mainly because the M NW breed is larger when compared to the M NR (NUNES et al, 2020).…”

“…Morphometry was measured in the last week prior to slaughtering the animals with a tape measure and a biometric rod adapted according to (ARAÚJO, et al, 2014;BIANCHINI et al, 2006;REZENDE et al, 2014). The lambs were kept in the correct upright position on a horizontal concrete floor without slope during the measurements.…”

Morada Nova lambs’ meat production potential description through morphometric evaluation

et al. 2023

Morada Nova breed has a low effective herd, and its white variety is in risk of extinction. The selection of individuals based on breed standard without correlation with productive aptitude is predominant today. We believe that the best way to rescue this valuable genetic resource is to describe its productive potential for commercial use. Thus, this study described the meat production potential of Morada Nova lambs through morphological and zoometric data, performance and carcass characteristics. Twenty-four non-castrated male lambs from two genetic groups were used: Morada Nova red (MNR) and crossbreed Morada Nova (red x Morada Nova white-MNF1) distributed in a completely randomized design. Univariate and multivariate analysis were used. The yields of commercial cuts and the physicochemical characteristics and qualitative measurements of the carcass were similar between the genetic groups. Seven of the 28 characteristics of the carcass were greater in MNF1 lambs. The chest height, rump height and anamorphosis index showed to be important variables in the choice of MN lambs with meat production potential. Based on factor and hierarchical cluster analysis, the Morada Nova beef morphometric index (MNBMI) was created. Both of groups have high thoracic development, ability to produce meat, weight gain, feeding efficiency and breathing capacity, infusing greater rusticity and adaptability; however, the application and validation of the developed index showed superiority for meat production in the crossed lambs. Thus, the MNF1 lambs are a sustainable option for sheep production in drylands.

“…These measurements were combined to calculate the following indexes for conformity, production suitability (milk and meat), and ethnology (Marchiani Dubuc, 1991;Contreras et al, 2011;Rezende et al, 2014a): anamorphic index (thoracic perimeter squared divided by withers height, multiplied by 100); pelvic index (rump width divided by rump length, multiplied by 100); withers-to-rump ratio (withers height divided by rump height); body index (body length divided by thoracic perimeter); lateral-body index (withers height divided by body length, multiplied by 100); relative body index (body length multiplied by 100, divided by withers height); body capacity index 1 (quotient between weight and body length); body capacity index 2 (quotient between weight and thoracic perimeter); transversal pelvic index (rump width divided by wither height, multiplied by 100); longitudinal pelvic index (rump length divided by withers height, multiplied by 100); and thoracicperimeter-to-withers ratio (thoracic perimeter divided by withers height).…”

“…For instance, the evaluation of the pelvic area of buffalo cows can contribute to identify animals with not as many delivery problems. Another tool for phenotypic evaluation can be the combined use of body measurements to develop zootechnical indexes, which has been reported as an efficient strategy to investigate the suitability of domestic animals (Cerqueira et al, 2011;Contreras et al, 2011;Meneses et al, 2013;Rezende et al, 2014aRezende et al, , 2016.…”

-The objective of this work was to estimate the phenotypic diversity in Jafarabadi, Murrah, and Mediterranean buffalo cows (Bubalus bubalis). Thoracic perimeter, withers-and-rump height, body length, and biiliac, external biischiatic, external ilioischiatic, sacropubic, and mean biiliac diameters were measured. The following indexes were calculated: anamorphosis index, pelvic index, withers-to-rump ratio, body index, lateral-body index, relative body index, body capacity indexes 1 and 2, transversal pelvic index, longitudinal pelvic index, and thoracic-perimeter-to-withers ratio index. The effect of breed was evaluated using univariate (mean tests) and multivariate (size-free discriminant analysis and Fisher's linear discriminant function) analyses. The diversity among the breeds and their correlation with the variables were also evaluated using biplot graphs developed from principal component analysis. The breeds evaluated show a rectilinear, midline body model with similar capacity of muscular tissue development in body parts from which the most valuable cuts are extracted, and intermediate suitability for meat and milk production. The Jafarabadi breed has a larger body size, with a rear portion wider than longer, while the Murrah and Mediterranean breeds show similar biotypes, mainly differentiated in the pelvic region.Index terms: Bubalus bubalis, biometric measurements, pelvimetry, zootechnical indexes. Diversidade fenotípica em búfalas Jafarabadi, Murrah e MediterrâneoResumo -O objetivo deste trabalho foi estimar a diversidade fenotípica em búfalas (Bubalus bubalis) das raças Jafarabadi, Murrah e Mediterrâneo. Mensuraram-se perímetro torácico, altura de anterior e de garupa, comprimento do corpo e diâmetros do biilíaco, biisquiático externo, ilioisquiático externo, sacropúbico e biilíaco médio. Calcularam-se os seguintes índices: de anamorfose, pélvico, relação cernelha-garupa, corporal, corporal-lateral, corporal relativo, capacidade corporal 1 e 2, pélvico transversal, pélvico longitudinal e relação perímetro torácico-cernelha. Avaliou-se o efeito de raça por meio das análises univariada (teste de médias) e multivariada (análise discriminante independente do tamanho e função discriminante linear de Fisher). Também avaliaram-se a diversidade entre as raças e a sua relação com as variáveis, por meio de gráficos biplot, elaborados a partir da análise de componentes principais. As raças apresentam modelo corpóreo retilíneo, mediolíneo e com capacidade igual para desenvolvimento de tecido muscular em locais de onde são extraídos cortes nobres, com aptidões intermediárias para produção de carne e leite. A raça Jafarabadi apresenta maior porte corporal, assim como uma porção traseira mais larga do que comprida, enquanto a Murrah e a Mediterrâneo apresentam biótipos próximos, diferenciados principalmente na região pélvica.Termos para indexação: Bubalus bubalis, medidas biométricas, pelvimetria, índices zootécnicos.

“…Certain body measurements are limited by the physiological maturity of the animal (Sakamoto et al, 2014), in which measurements such as body length and croup height are directly related to, and limited by, the development of bone tissue, while thoracic girth, foreleg circumference, and body weight are mainly related to the development of muscle and adipose tissue, and follow their variation curves (Lee & Kim, 2010). As such, high, positively correlated responses between thoracic girth and body weight are to be expected (Rezende et al, 2014).…”

The objective of this work was to assess the effect of genetic group and heterosis on the relationship between body weight and morphometric measurements, in purebred and crossbred animals from the second (G2) and third (G3) generations of Nellore and Charolais calves. Body weight (BW), average daily weight gain (ADG), foreleg circumference (FC), thoracic girth (TG), body length (BL), and croup height (CH) were measured at birth and at 63, 210, and 365 days of age in animals from G2 and G3. Charolais animals were superior to Nellore ones for gains BW, ADG, BL, and TG, as well as for the ratio between BW gain and CH gain; Nellore animals were superior for CH gains. Crossbred animals of both generations were superior to the purebred animals for gains of BW, BL, and CH. In G2, the predominance of Charolais genes resulted in greater gains of BW, ADG, FC, and TG. The G3 animals were superior to the purebred animals for ADG, FC, and TG. No differences were found for the ratio between gains of weight and morphometric measurements. Heterosis and complementarity are apparent for weight and body measurements of crossbred calves from rotational crossings.
