- Phenotypic correlations between milk production and conformation traits in goats Mauricio Valencia-Posadas José Eleazar Barboza-Corona César Andrés Ángel-Sahagún Abner Josué Gutiérrez-Chávez Oscar Alejandro Martínez-Jaime Hugo H. Montaldo Multidisciplinarias (Ciencias Sociales) Type dairy goats nonlinear relationships In this work, we use the records from 643 goats in order to evaluate the phenotypic relationships between conformation traits and milk production in goats. Correlations were estimated using data on goats which included fifteen conformation traits and first lactation milk yield adjusted for age, calving month and 305 milking days (MY1). We also compared the average scores for type traits on the goats under study with those on a sample of goats from the United States of America (USA). Correlations between conformation traits and MY1 were estimated and an analysis was performed to evaluate the nonlinear relationships between them. The highest correlations were found between milk production and udder depth (–0.22), stature (0.18) and rear udder side view (0.12) (p < 0.05), non-linear (cubic) effects for stature and strength being significant (p < 0.05). American goats had a better overall conformation than the Mexican ones but results indicated that goats with better body conformation were not the best for milk production. 2017 artículo científico 0188-6266 https://www.redalyc.org/articulo.oa?id=41652062001 en http://www.redalyc.org/revista.oa?id=416 Acta Universitaria application/pdf Universidad de Guanajuato Acta Universitaria (México) Num.3 Vol.27
