    Studies on Genetic and Phenotypic Parameters of Some Economic Traits and Construction of Selection Indices in Black Bengal And Its Beetal Half-Bred Goats
    (Birsa Agricultural University, Ranchi, 1997) Devesh Kumar Singh; Dr.S.K.Verma
    1. Beetal halfbreds were superior to purebred Black Bengal with respect to growth under farm condition of management. II. Males were significantly heavier than females at birth. III. The body weight and body biometries were more in single barn kids than that of twins. IV. Winter born kids were significantly heavier than that of summer and monsoon barn kids in both the genetic groups. V. All growth traits were significantly better during early years of establishment of farm. VI. Body weights, biometries and daily gain in weight during 0-3 and 3-6 months of age had generally significant positive linear association with birth weight and dam's weight at kidding. VII. Beetal halfbreds were superior to that of pure bred Black Bengal goats in most of the milk production and reproduction traits.
