      A survey was conducted in order to study changes in body measurements in the Chiapas sheep breed. For this purpose 66 males and 79 females of various ages were measured: body weight, chest girth, knee perimeter, cannon ...
    • Biometrical multivariate study of the Zambian indigenous Fat-tailed sheep. 

      Parés Casanova, Pere-Miquel; Mwaanga, Edwell S.; Caballero-Sala, Marta; Sabaté, J.; Valenzuela, Sílvia (Academic Journals, 2013-11-12)
      Body weight and twelve body measurements taken on fifteen ewes and five rams of the Zambian indigenous Fat-tailed were analysed. The sheep were extensively managed in the Southern and driest part of Zambia. The aim of the ...
    • Comparación de modelos no lineales para describir curvas de crecimiento según sexo en el borrego Chiapas 

      Parés Casanova, Pere-Miquel; Caballero-Sala, Marta; Perezgrovas Garza, Raúl (Universidad Nacional Mayor de San Marcos. Facultad de Medicina Veterinaria, 2015-01-01)
      The aim of this study was to establish the growth curves in ovine Chiapas breed according to sex. Three models were used: logistic, von Bertalanffy and Gompertz. Body weight data were obtained from 66 males and 79 females ...
    • Crecimientos diferenciales según fenotipos en el Borrego de Chiapas 

      Parés Casanova, Pere-Miquel; Caballero-Sala, Marta; Perezgrovas Garza, Raúl (Red CONBIAND, 2013)
      Growth curves in the Chiapas sheep breed were assessed for males and females, comprising a wide age range of animals (3 to 156 months). Animals encompass 4 different phenotypes (white n=30, black n=77, tan n=28 and paint ...
    • Estimating live weight of Chiapas breed for males and females 

      Parés Casanova, Pere-Miquel; Caballero-Sala, Marta; Pérezgrovas, R. (Medlife Scientific Press, 2014-11-24)
      Weight tapes and body weight estimation formulas are routinely used to determine the body weight of domestic mammals when a scale is not available. A sample of 145 animals (79 females and 66 males) of different ages (from ...
    • Estimating live weight of sheep of Guatemala by a simple formula 

      Parés Casanova, Pere-Miquel; Caballero-Sala, Marta; Vilà, L. (Economy Computing Optimization Risks Finance Adminsitration Net Business, 2014-12-20)

    • Live weight estimation of fat-tailed indigenous ewes from Southern Zambia 

      Parés Casanova, Pere-Miquel; Mwaanga, Edwell S.; Caballero-Sala, Marta; Valenzuela, Sílvia; Sabaté, J. (Indian Council of Agricultural Research, 2013)
      Body measurements can be used to predict live weight fairly well in a situation where weighbridges are not available (Goonerwardene and Sahaayuraban 1983). The accuracy of functions used to predict live weight or growth ...
    • Live weight estimation of Gwembe goat (Capra hircus) from measurement of thoracic girth 

      Parés Casanova, Pere-Miquel; Mwaanga, Edwell S.; Caballero-Sala, Marta; Sabaté, J.; Valenzuela, Sílvia (African Association of Veterinary Anatomists, 2012)
      Thoracic girth was taken and corre-lated with live weight from 41 goats (30 females and 11 males) in South Zambia under on farm condition. Live weight was estimated using a linear model. Coefficient of determination (R2) ...
    • Possible tendency of polled cattle towards larger ears 

      Parés Casanova, Pere-Miquel; Caballero-Sala, Marta (Universidad de Antioquia. Facultad de Ciencias Agrarias, 2014)
      Background: the anatomy and physiology of bovid horns are consistent with their thermoregulatory function. Objective: to evaluate a possible correlation between ear and horn size, as key factors for body thermoregulation. ...
