    Poultry :

    1. Mapping of frizzle gene using microsattelite markers was done in White Leghorn breed and OPP-9, OPB-19, OPA-6 and CC-10 random promers were used for polymorphoism in analysis in white naked neck broilers and coloured broiler developed at CVRI, Izatnagar. Frizzle locus has shown a linkage 3.18 LOD score with ROS-54 and 2.56 LOD score with MCW 188 microsatellite markers.The study has indicated that Na / na (Naked neck heterozygous) or na / na (normally feathered) broilers are genetically similar and genetic distance is less among naked neck and normal broilers.

    2. The relative performance of naked neck and normally feathered broilers were evaluated in white and coloured lines for growth, viability. Generally the naked neck broilers were superior to normally feathered broilers for growth, feed efficiency, carcass traits, viability, immunocompetence and blood biochemical parameters for lipid profile in both the lines. The naked neck broilers exhibited higher dressing percentage, ratio of meaty to none cuts along with lower concentration of blood biochemical parameters (Total cholesterol, HDL, Triglycerides, VLDL & LDL) and significantly higher abdominal fat compared to normally feathered broilers. and CMI response against PHA-P exhibited a significant superiority for homozygous & heterozygous naked neck over normally feathered broilers. The RAPD-PCR profile revealed that the genetic polymorphism exist in the broiler population with respect to 0 random primers used in the study. The naked neck broilers produced equal or more number of bands compared to normally feathered broilers. The line specific bands have been produced by naked neck & normally feathered broilers with indication of little genetic distance between the birds of same genetic group.

    3. Various restricted and unrestricted multi-trait selection indices incorporating the egg production to 40 weeks of age, egg weight, ASM, 18 & 32 weeks body weights in different combination were constructed and evaluated for improving the egg production in a closed flock of White Leghorn. The unrestricted multitrait multisource selection index incorporating the individual information for all the five traits and individual plus full and half sibs information for egg production only with an accuracy of 0.7058 and expected aggregate genetic gain of 4.0296 eggs per generation was found to be the most desirable for improving the egg production. With a moderately low estimate for egg production the heritability for ASM and BW32 were moderately high. However, the egg weight and 18-week body weight were highly heritable. The estimates of heritability from dam component were higher than sire component for almost all the traits indicating the importance of non additive genetic and / maternal effects for inheritance of EP40, ASM, BW18, & BW32. genetic correlations of egg production from sire component with EW35, ASM, BW18 & BW32 were - 0.554±0.208, -0.222±0.259 & 0.630±0.211, respectively. In most of the cases, the estimates of genetic correlations from sire component were higher than dam component indicating the importance of sex linked effect in influencing the genetic co-variances among these traits.

    4. Feed efficient broilers, layers and dual purpose chickens were developed for distribution among farmers.

    Buffalo :

    1. Morphological characteristics of Tarai buffalo has been detailed as 87% of animals are black in colour with grayish brown hairs, which remains straight. Some of the animals have white marking on the poll. Horns are sickle shaped and black in colour with backward orientation. Body is compact. Body length, pouch girth, height at withers, length of fore limb and hind limb of young males are 60.61± 1.38 cm, 81.64±1.92 cm, 73.92±1.29 cm, 49.24± 0.78, 13.13±0.38 cm respectively while that of females it is 56.22± 0.75 cm, 80.04± 1.13 cm, 71.74± 0.56 cm, 50.24± 0.41 cm and 12.41± 0.14 cm respectively.

    2. Karyo-typing of Tarai buffalo indicated that X-chromosome is the fourth largest acrocentric while Y-chromosome is smallest acrocentric as in Murrah breeed. The relative length of 50 chromosomes ranged from 1.49± 0.8 to 7.84± 0.15 and 1.41± 0.02 to 7.99± 0.09 for smallest to largest Tarai Murrah buffalo respectively.

    3. Various grades of crossbred cattle incorporating indigenous cattle were developed with a production potential of 2800-3200 kg of milk.

    4. Murrah buffaloes were improved to produce 1800 kg of milk.
