Himachal Pradesh Public Service Commission, known commonly as HPPSC, is a government agency and topmost constitutional body of Government of Himachal Pradesh. Here is a detailed syllabus for HPAS Main Exam Optional Paper 2.
Optional Paper – Animal Husbandry And Veterinary Science
PAPER-I
- Animal Nutrition: energy sources, energy metabolism and requirements for maintenance and production of milk, meat, eggs and work.
- Advanced studies in nutrition-protein- source of protein, its metabolism and synthesis, protein quality in relation to requirements. Importance of energy protein ratio in rations.
- Advanced studies in nutrition-minerals- sources, functions, requirements and their interrelationships including trace minerals.
- Vitamins, hormones and growth stimulating substances-sources, functions, requirements and interrelationship with minerals.
- Advanced ruminant nutrition-Dairy cattle – nutrients and their metabolism with reference to milk production and its composition. Nutrient requirements for calves, heifers, dry and milking cows and buffaloes.
- Advanced non-ruminant nutrition-poultry- nutrients and their metabolism with reference to poultry meat and egg production. Nutrient requirement and feed formulation for broilers at different ages.
PAPER-II
- Principles of Animal Breeding: Introduction to Animal Breeding; probability; HardyWeinberg law, its application and significance; phenotypic variance and its partitioning; heritability and its estimation; repeatability; principles of inbreeding; coefficient of relationship; out breeding and heterosis.
- Population Genetics Applied to Animal Breeding: Measured variance of population; approach to equilibrium under random mating; genetic and environmental sub-divisions of phenotypic variance; contrast between Mendelism and blending inheritance; genetic nature of differences between groups; resemblances between relatives in population; mating at random; forces affecting gene frequency; their impact in animal breeding; heritability and repeatability, methods and precision of estimation; aids to selection; breeding for threshold characters; selection index selection.
- Breeding Systems: Biometrical relations between relatives; mating systems; inbreeding; out breeding; phenotypic assortative mating; general and specific combining ability; choice of effective breeding plans; calculation of inbreeding coefficients using Wright’s and Malacot’s approach; co-variance among relatives; decreases of heterozygosity on inbreeding; problems of detection of non-additive genetic variance.
