Introduction to Animal Husbandry and Livestock in Haryana

  • Animal husbandry is the branch of agriculture dealing with breeding, feeding, housing, health care and economic use of domesticated animals.

  • Haryana's livestock economy is dominated by dairy: buffaloes outnumber cattle in milk contribution, and crossbred cattle (Holstein Friesian and Jersey crosses) supply most of the bovine milk from cattle.

  • Haryana districts with the largest livestock concentrations include Hisar, Bhiwani, Jind, Sirsa, Karnal and Kurukshetra; Hisar hosts the state veterinary university (Lala Lajpat Rai University of Veterinary and Animal Sciences) and a central buffalo research institute.

  • Major livestock species of the state in order of economic importance: buffalo, cattle, goat, sheep, poultry, pig, camel (sparse, mainly in dry western tracts) and equines.

  • Livestock census data are collected every five years by the Government of India; the 20th census was conducted in 2019, so state planners quote 2019 figures until the next census.

  • Haryana's Murrah buffalo and Hariana cattle are the state's internationally recognised indigenous breeds; both are also exported as breeding stock.

  • Mixed crop-livestock farming is the norm: wheat-rice and wheat-mustard rotations supply straw (bhusa) and fodder, while dung supplies farmyard manure.

  • Livestock contributes roughly one-third of the state's agricultural gross value output; milk alone is the single largest livestock product by value.

  • Institutional support in Haryana includes the Department of Animal Husbandry and Dairying, Haryana Dairy Development Cooperative Federation (Vita), and the Haryana Livestock Development Board.

Breeds of Cattle and Buffaloes

  • Murrah: premier Indian buffalo breed, black coat with white switch, tightly curled horns, heavy body; average lactation yield about 1500-2500 kg with 6.5-7% fat; origin Rohtak, Hisar and Jind tracts of Haryana.

  • Nili-Ravi: riverine buffalo of Punjab (Pakistan) and adjoining Indian Punjab; black coat with white markings on face and legs, wall eyes; high fat milk, good for canal-irrigated areas.

  • Surti: Gujarat buffalo, medium size, two white chevron collars on the neck, horns sickle-shaped; fat about 7%, moderate yield.

  • Jaffarabadi: heaviest Indian buffalo, Gujarat (Saurashtra), long drooping horns, high milk yield but later maturity.

  • Hariana: dual-purpose Haryana cattle, white to grey coat, compact body, medium milk yield (about 1000-1500 kg per lactation) with good draught capacity.

  • Sahiwal: red-brown cattle of Punjab (Pakistan) and Indian Punjab, loose skin, heavy dewlap; best indigenous milch cattle for hot climates, high fat milk.

  • Gir: Gujarat zebu, red with white patches, prominent forehead, long pendulous ears, disease-resistant; widely used in crossbreeding for tick resistance.

  • Red Sindhi and Tharparkar: red and white-grey milch zebu breeds respectively; Tharparkar (Rajasthan) is dual-purpose with good heat tolerance.

  • Crossbred cattle in Haryana are mainly Holstein Friesian x Hariana and Jersey x Hariana; crossbreds yield far more milk but need more concentrate and are less heat- and tick-tolerant than zebu cattle.

Breeds of Sheep, Goats, Pigs, Poultry and Other Livestock

  • Nali and Chokla: Rajasthan sheep breeds; Chokla is a carpet-wool breed with fine wool, Nali gives medium wool; both are found in adjoining Haryana areas.

  • Hissardale: sheep breed developed at Hisar by crossing Bikaneri (Nali-type) ewes with Australian Merino rams for fine wool.

  • Beetal: large dairy goat of Punjab and Haryana, red-brown with black patches, long pendulous ears, high milk yield (about 2-3 kg/day) and prolificacy.

  • Jamunapari: tall, white dairy goat of Uttar Pradesh (Chakarnagar); long ears, Roman nose, high milk yield, but low prolificacy.

  • Sirohi, Barbari and Black Bengal: Sirohi (Rajasthan) is dual-purpose meat and milk; Barbari is a small prolific goat of Uttar Pradesh; Black Bengal is a high-prolificacy meat goat of eastern India.

  • Pigs: exotic breeds used in India include Large White Yorkshire, Landrace and Hampshire; indigenous Ghungroo (West Bengal) and Niang Megha (Meghalaya) are native breeds.

  • Poultry: indigenous Aseel (fighting type, heavy), Kadaknath (black meat, Jhabua, Madhya Pradesh) and Bursa; commercial layers use White Leghorn-type hybrids and broilers use Cornish x White Plymouth Rock crosses.

  • Turkey, duck, quail and guinea fowl are minor poultry species; ducks (Khaki Campbell) are suited to waterlogged and coastal areas.

  • Camel breeds in India include Bikaneri, Jaisalmeri, Kachchhi and Bamel; camels are a state animal of Rajasthan, not a major Haryana species.

Feeding and Nutrition of Livestock

  • Balanced ration: a feed mixture supplying all nutrients in the proportion and amount needed for 24 hours; a ration is the total feed given per day, a feed is any single ingredient.

  • Maintenance requirement of a dairy animal is roughly 1 kg of total digestible nutrients (TDN) per 100 kg body weight per day; a common thumb rule is 2 kg dry matter per 100 kg body weight.

  • Concentrate allowance for milk production commonly follows 1 kg concentrate per 2.5 kg milk for buffalo (higher fat) and per 2.5-3 kg milk for crossbred cattle, over and above maintenance.

  • Crude protein requirement is about 12-14% of dry matter for growing and high-yielding animals; urea-treated straw and bypass protein improve nitrogen supply.

  • Urea molasses mineral block (UMMB) is a supplementary lick containing urea, molasses, minerals and binding agents; urea must be introduced gradually to avoid ammonia toxicity.

  • Mineral mixture is essential for high producers; calcium-to-phosphorus ratio of roughly 2:1 is recommended, with salt and trace minerals (zinc, copper, cobalt, iodine, selenium) included.

  • Green fodder (berseem, lucerne, maize, sorghum) supplies carotene and protein; dry straw supplies energy but is low in protein and minerals, so it must be supplemented.

  • Water intake of a dairy animal is roughly 3-5 litres per litre of milk produced, in addition to maintenance needs; water should be clean and available ad libitum.

  • Anti-nutritional factors: sorghum and sudan grass can release cyanide (HCN) when young or drought-stressed; karanj and castor cake must be detoxified or avoided; cottonseed cake gossypol limits use in young stock.

Housing, Care and Management of Livestock

  • Loose housing: animals are kept in an open paddock with a covered shed and a common feeding and watering area; it is cheaper and allows free movement, and is recommended for dairy herds.

  • Floor space standards: about 40 sq ft covered area and 80-120 sq ft open area per adult cattle/buffalo in loose housing; cubicles in conventional barns are about 4-5 ft wide and 7 ft long per animal.

  • Mangers should be about 2.5-3 ft high for cattle and buffalo, with a feeding space of about 2.5-3 ft per animal; water troughs must be cleaned daily.

  • Orientation: sheds should have a long axis running east-west to reduce direct sun on the long walls, with adequate ridge ventilation and a height of about 10-12 ft at the ridge.

  • Dairy calf management: colostrum (first milk) must be fed within the first 1-2 hours of birth, about 10% of body weight in the first 24 hours, because it provides immunoglobulins.

  • Dehorning and disbudding are done in calves (disbudding by 2-4 weeks); castration of non-breeding males is done by Burdizzo or elastrator at 2-4 weeks to 3 months.

  • Deworming schedule: calves are dewormed at about 2-4 weeks and then every 3-4 months; adults are dewormed at least twice a year, more often in high-humidity areas.

  • Identification and records: ear tagging, tattoo or branding for identification; a daily record of milk yield, feed, breeding and health events is maintained per animal.

  • Summer management includes shade, fans, foggers and wallowing; heat stress in buffaloes shows as reduced feed intake, increased respiration and lower milk yield.

Animal Health, Common Diseases and First Aid

  • Foot-and-mouth disease (FMD): viral, highly contagious; vesicles on tongue, gums and hooves, salivation, lameness, high fever; vaccination of all cloven-footed animals every 6 months is the main control measure.

  • Haemorrhagic septicaemia (HS): bacterial (Pasteurella multocida), acute septicaemia with high fever, swelling of the throat and neck, death within 24-48 hours; annual vaccination before the monsoon is standard.

  • Black quarter (BQ): Clostridium chauvoei infection causing crepitating muscle swelling, especially in young cattle; vaccination is given annually before the rainy season.

  • Brucellosis: bacterial (Brucella abortus) causing abortion in the last trimester, retained placenta and infertility; calfhood vaccination with S19 or RB51 in female calves and test-and-slaughter control.

  • Mastitis: inflammation of the udder, commonly bacterial; diagnosis uses the California Mastitis Test (CMT) or somatic cell count; control relies on teat dipping, dry-cow therapy and clean milking.

  • Milk fever (parturient paresis): hypocalcaemia near calving, recumbency with cold extremities and lowered head; treatment is slow intravenous calcium borogluconate.

  • Ketosis and bloat: ketosis is energy deficiency in early lactation (sweet smell of acetone on breath); bloat is ruminal gas accumulation treated by passing a stomach tube or trocarisation in emergencies.

  • Parasites: ticks (Babesia, Anaplasma), liver flukes (Fasciola) in waterlogged areas, and gastrointestinal nematodes; control by rotational grazing, acaricides and strategic deworming.

  • First aid basics: control bleeding with pressure, immobilise suspected fractures, keep the animal warm and quiet, and call a veterinarian; do not administer antibiotics without advice, and observe milk withdrawal periods.

Breeding, Reproduction and Improvement of Livestock

  • Puberty in buffalo heifers is about 15-18 months (delayed compared with cattle at 12-15 months); first calving in buffalo is typically at 3-3.5 years.

  • Oestrous cycle: about 21 days in cattle (range 18-24), about 21 days in buffalo; oestrus duration is about 12-18 hours in cattle and 24-36 hours in buffalo, with silent heats common in buffalo.

  • Ovulation occurs about 10-14 hours after the end of oestrus in cattle; the best time to inseminate is the AM-PM rule, i.e. inseminate in the afternoon if seen in heat in the morning and vice versa.

  • Gestation period: about 280-285 days in cattle, about 305-310 days in buffalo, about 150 days in goats and sheep, about 114 days in pigs.

  • Artificial insemination (AI) uses frozen semen at -196 degrees Celsius in liquid nitrogen; post-thaw motility should be at least 50% for acceptable semen quality.

  • Selection and breeding methods: purebreeding, inbreeding (increases homozygosity but risks inbreeding depression), outcrossing, crossbreeding (e.g., Holstein x Hariana for milk) and grading up for upgrading nondescript stock.

  • Pregnancy diagnosis: rectal palpation from about 45-60 days, or ultrasonography earlier; non-return to heat at 21 days is only presumptive evidence.

  • Buffalo oestrus detection aids include teaser bulls, pedometers and heat-detection patches; the cervix is grasped rectally during AI in buffalo.

  • Reproductive disorders: repeat breeding, anoestrus (common in buffalo, treated with hormonal therapy and improved nutrition) and retained placenta; the calving interval target is about 12-13 months.

Milk Production, Dairy Practices and Value Addition

  • Milk composition of cow milk: about 87% water, 3.5% fat, 3.3% protein, 4.8% lactose and 0.7% minerals; buffalo milk has about 7% fat and 4% protein, giving higher total solids.

  • Specific gravity of cow milk is about 1.028-1.030 and of buffalo milk about 1.030-1.032; adulteration with water lowers specific gravity.

  • Milk is a good medium for bacteria, so it must be cooled to about 4 degrees Celsius within 1-2 hours of milking; the methylene blue reduction test and standard plate count assess bacteriological quality.

  • Clean milk production: wash udder and hands, use dry wiping and foremilk stripping in a strip cup, use stainless steel utensils sanitised with hot water or chlorine, and exclude the first few streams of foremilk from the bulk.

  • Pasteurisation: HTST at 72 degrees Celsius for 15 seconds or LTLT at 63 degrees Celsius for 30 minutes; the phosphatase test confirms effective pasteurisation.

  • Value-added dairy products: ghee, paneer, curd (dahi), khoa, butter, flavoured milk, ice cream and cheese; paneer yield is roughly 18-20% from buffalo milk and 14-16% from cow milk.

  • Ghee is clarified butterfat; its quality is judged by the Reichert-Meissl (RM) value, Butyro-Refractometer reading and free fatty acid content.

  • Cream separation by gravity (cream layer) or centrifugal separator; the fat content of cream is expressed as a percentage, and standardised milk adjusts fat to a target.

  • Milk marketing channels: cooperative (Vita, Amul pattern with village dairy cooperatives), private processors and direct sale; the cooperative model pays members on a fat and solids-not-fat basis.

Poultry and Piggery Enterprise Management

  • Brooding temperature for chicks: about 95 degrees Fahrenheit (35 degrees Celsius) in the first week, reduced by about 5 degrees Fahrenheit per week until 70 degrees Fahrenheit or ambient temperature.

  • Broiler performance targets: market weight of about 2-2.2 kg at 42 days with a feed conversion ratio (FCR) of about 1.6-1.8; layer performance is judged by hen-housed egg production and feed per dozen eggs.

  • Floor space: about 1 sq ft per broiler up to market age and about 2-2.5 sq ft per layer; cage systems give higher density but need careful ventilation.

  • Ventilation and litter: litter (paddy husk, sawdust) should be 2-3 inches deep and kept dry; ammonia levels above 25 ppm irritate the respiratory tract and cause ascites and poor growth.

  • Lighting: continuous light for the first 2-3 days, then 20-23 hours per day for broilers; layers need 14-16 hours of light per day to sustain egg production.

  • Vaccination schedule: Marek's disease at day-old in the hatchery, Newcastle disease (Ranikhet) at 5-7 days (F1 or LaSota) and again at 28 days, infectious bursal disease at 14 and 21 days, and fowl pox at 6-8 weeks.

  • Biosecurity essentials: footbaths, restricted visitor entry, all-in all-out batches, rodent and wild-bird control, and disposal of dead birds by deep burial or incineration.

  • Piggery: gestation about 114 days, litter size 8-12 piglets, weaning at 6-8 weeks; a boar-to-sow ratio of about 1:10 for natural service; iron injection for piglets to prevent anaemia.

  • Economics: feed accounts for about 65-70% of poultry production cost, so FCR and feed price dominate profitability; pig feed is similarly dominated by energy and protein cost.

Entrepreneurship, Marketing and Extension in Animal Husbandry

  • A dairy unit of 10 crossbred cows or buffaloes is a common bankable project size; project reports must include capital cost, working capital, projected income, depreciation and repayment schedule.

  • Institutional credit sources: NABARD refinance, Kisan Credit Card (extended to dairy and fisheries), and state-level schemes such as the National Livestock Mission and Rashtriya Gokul Mission.

  • Subsidy norms: the National Livestock Mission and Dairy Entrepreneurship Development Scheme (DEDS) provide capital subsidy, typically 25% for general and 33% for SC/ST/women beneficiaries, subject to scheme ceilings.

  • Marketing: milk is sold to cooperatives on a fat and SNF basis, to private processors on a per-litre basis, or directly to consumers; value addition (paneer, ghee, flavoured milk) raises margin but needs licensing and cold chain.

  • Extension methods: individual contact (farm visits, office calls), group contact (demonstrations, field days, farmer interest groups) and mass media (radio, television, print, mobile advisory services).

  • Key extension concepts: the diffusion of innovations model (innovators, early adopters, early majority, late majority, laggards) and the adoption process (awareness, interest, evaluation, trial, adoption).

  • Livestock insurance is available under the Livestock Insurance Scheme with premium subsidy; animals are identified by ear tag, and claims require post-mortem certification.

  • Registration and compliance: FSSAI licence for dairy processing, Pollution Control Board consent for piggery and poultry, and vaccination and veterinary health certificates for animal movement.

  • Farmer producer organisations (FPOs) and self-help groups improve bargaining power, input purchase and collective marketing of milk and meat.
