Morphological measurements and body indices for Cuban Creole goats and their crossbreds

Abstract

-In this work, linear body measures were taken and production indices calculated for 100 Cuban Creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in Cuba. Low variation was found for all indices of the Creole goats, showing homogeneity between the groups of animals studied. Most of the functional indices are related to the milk biotype which is in agreement the possible origin of the breed from animals of the Iberian Peninsula and Canary Islands. The crossbreds were more varied, mostly due to undesigned disorganized crossing. These data may help in identifying a commercial niche for the breed and contribute to in situ conservation of the Cuban Creole goat.

Caracterização fenotípica de ovelhas dos humedales de Ite, sul do Peru: dados preliminares

“…Esta suposta miscigenação do rebanho B aparentemente influiu no maior tamanho corporal, assim como relata Chacón et al (2011) em caprinos mestiços da raça Anglonubiana.…”

“…Assim se resgataria os ovinos crioulos em núcleos de conservação, e exploraria os animais mestiços para aproveitar possíveis vantagens zootécnicas produto da heterose, lembrando que cada biótipo possui exigên-cias diferentes, as quais devem estar de acordo com a realidade dos criadores (Chacón et al, 2011).…”

Classification of goat genetic resources using morphological traits. Comparison of machine learning techniques with linear discriminant analysis

“…The Florida, Murciano Granadina and Azpi Gorri breeds were the poorest differentiated breeds in all the methods employed (hierarchical and non-hierarchical), The inclusion of an index that relates the size of the head and the body as a variable could be important to classify the Florida and Azpi Gorri breeds. Herrera et al (2003) noted that the cephalic index was particularly high in the Florida and Azpi Gorri breed and are related to the milk biotype (Chacón et al, 2011). The good rates of breed classification and the improvement of hierarchical system over those obtained using the LDA system, validate the effectiveness of these methods for classification problems.…”

Development and validation of a visual image analysis for monitoring the body size of sheep

“…Generally, the parameters of body size consist of four type indicators: body length, body width, body height and circumference (Mayaka et al 1996;Chen et al 2008;Shi et al 2008;Chacón et al 2011;Wang et al 2011;Bingöl et al 2012). In order to achieve sufficient accurate measurements, multiple views from different angles must be used.…”
