Size sexual monomorphism in Barroso-Salmeco cattle from Guatemala
MetadataShow full item record
Sexual dimorphism in size (SSD) is a widespread phenomenon in animals. Its causes remain obscure, as well as its allometric relationship with body size (Rensch's hypothesis). Here, in order to contribute a better description of the Barroso-Salmeco cattle from Guatemala, we analyze SSD in 5 bulls and 49 females aged more than 3 years, using 23 lineal morphostructural traits and body weight. It was detected no SSD, and only cannon thickness appeared different between genders. Results of sexual dimorphism analyses discard male-biased sexual size differences in this breed and they point rather towards a sexual monomorphism.

Morphostructural characters of the domestic Bacyard Creole Duck (Cairina moschata) in three communities of Guatemala Jáuregui, R.; Gonzáles, Mario E.; Lorenzo, C.R.; Folgar, Ana M.; Isern, Ana; Parés Casanova, Pere-Miquel (Red CONBIAND, 2020-11-27)Domestic Creole ducks (PCDs) are hardy, less nutritionally demanding, less susceptible to disease, and promising among native species due to their rapid growth rate. In Guatemala, PCDs are part of the biological heritage ...
