- 2. Basic Definitions and Terminologies Balanced Diet → One which provides different kinds of nutrients in certain quantities and proportions of all the required nutrients Optimizing → Make the best use of a resource (or) Most effective use of a resource Animal Production → Meat, milk and eggs Animal Productivity → Birth rate, mortality rate, off-take rate, etc. Diet Ration Balanced Ration
- 3. Nutrients Macro Nutrients Micro Nutrients Vitamins Minerals Water
- 4. Importance of Minerals Minerals are inorganic elements Required for the metabolic functions, growth, milk production, reproduction and health Animal cannot synthesize minerals inside its body, it needs to supplement through diet Feed and fodders are very poor source of minerals; do not provide all the minerals required for an animal Animal should be supplemented with adequate amount of good quality mineral mixture in their ration
- 5. Use of Nutrients Feed or Diet Water CHO Protein Lipid Vitamin Mineral Nutrients to tissue (in blood) Maintenance Growth Work Milk, egg & meat etc. (Production functions) Digestion Faeces Metabolism Urine Gas Heat
- 6. Use of Nutrients Importance of feed and fodder Feed and fodder Essential for life To exploit maximum genetic potential Underfeeding → Deficiency disorders and ill health (reduced immunity) Underfeeding → Reduced growth, reproduction and production Fodders (green and dry) → Play a major role in Ruminant ration Provides bulkiness & source of fibre Green fodder → cooling effect Available in plenty → ↓ concentrate feeding → ↓ production cost Poor availability → ↑ concentrate feeding → ↑ production cost
- 7. Need of Ration Balancing Concentration of nutrient is extremely variable between feed ingredients Forages are rich in fibre Grains are rich in energy and Oil cakes are rich in protein Sole feeding of one particular feed ingredient may not be capable of meeting all the nutrient needs of an animal Phytates and oxalates → Reduces dietary mineral (i.e., calcium, phosphorus and zinc) availability Therefore, preparation of balanced ration using different feed ingredients and supplementing deficit nutrients is vital for augmenting the productivity of an animal In livestock rearing, 65-70% of the total cost is attributed to feeding Minimizing the expense towards feeding increases the profit Roughages are low in TDN Concentrates are high in TDN
- 8. Desirable characteristic of a ration The Ration should be properly balanced The ration must be Palatable Variety of Feed in the Ration The Ration should contain enough of mineral matter The Ration should be fairly Laxative The Ration should be fairly bulky The ration should contain sufficient green fodder Avoid sudden changes in the ration Maintain regularity in Feeding The Feed must be properly prepared A Ration should not be too bulky Economy in Labour and Cost
- 9. Current Scenario in Balanced Feeding - India Dairy cows → Poorly adopted (70 % dairy farmers are landless and marginal farmers) Sheep and Goat → Poorly adopted Swine → Poorly adopted (Non-availability of commercial feeds in the market) Poultry → Comparatively well adopted (Integration system) Fish and Shrimp → Comparatively well adopted Problems Solutions Very poor awareness of quality feed, which hinders productivity Farmers training → Through experts Farmers lack information on feeding & management practices Farmers not interested in quality feed because of the low price of milk and other livestock products Good price for milk Good price for other livestock products Low capability of purchasing feeds and fodder Preparation of concentrate mixture at farm gate level reduces the production cost Inadequate feeding / Underfeeding Training on ration balancing Ensuring quality feed supply
- 10. Why Balanced Ration? Dairy cows Prior to white revolution Low milk yield Mainly for manure, plowing and bullock carting Very good pastures, grazing lands → Nutritional needs are met After white revolution → Dairying became an industry Genetic improvement (Cross breeding) → ↑ milk yield and faster growth rate Mainly for milk production Lack of pastures and grazing lands Transition of production practice → Free-range grazing to confined housing Concentrate feeding is essential to meet the requirements Poultry → Backyard to deep litter or cage system Faster growth rate of broilers → from 9 weeks it came to 6 weeks Layers → from 100 eggs to 300 eggs Other species → for the better production and productivity
- 11. To acquire maximum genetic potential → “Nutritionally balanced diet” is indispensable Livestock should be fed with balanced ration based on its body weight and production performance → To acquire maximum genetic potential Imbalanced feeding Leads to excess feeding of some nutrients whilst others remain deficient Affects various physiological functions; including long term animal health, fertility and productivity Feeding a well-balanced ration can lead to greater returns in the long term, in areas such as immune function, reproduction, growth and maintained body condition Why Balanced Ration?
- 12. Consequence of Imbalanced Feeding in Dairy Cows Slow growth & Delayed age at 1st calving Poor growth and Reproduction Longer calving intervals & Shorter lactation length Low milk production Shorter productive life ↑ Metabolic disorders (Milk fever, ketosis, etc.) ↑ Carbon foot print Excess feeding Waste of nutrients, nutrients excreted in faeces, environmental pollution, more feeding cost and less profit Under feeding Drain of stored nutrients from the body (ATM machine) Short term → Deficiency symptoms Long term → Deficiency diseases and disorders High concentrate feeding → SARA or Acidosis Low energy diet → Ketosis (Cattle & Pregnant sheep) Low protein diet → Poor growth (Broilers) Low calcium diet → Milk fever Low calcium diet → Leathery eggs, weak bones & rubbery beak (Laying hens)
- 13. Benefits of Balanced feeding – Dairy cows Improvement in milk production & quality (fat and Solids-not-fat (SNF)) Possible reduction in daily feeding cost → ↑ in net daily income Improvement in reproduction efficiency of animals Reduction in calving interval and as a result increase in productive life Improvement in the growth rate of calves → early maturity & calving Better immune response, hence better resistance against diseases (↑ IgG, IgM and IgA) Reduction in methane emission (15 – 20 percent per kg milk produced) Reduction in nitrogen excretion
- 15. Better utilization of Available Resources Fodder and crop residue utilization Rice straw → baling → avoid burning Rice straw → bulky feeds for ruminants Paddy straw / wheat straw → urea treatment Green / dry fodder → chaffing → reduce wastage and improves digestibility Chaff cutter (hand/power operated) Hydroponic fodder production Surplus green fodder → silage making
- 16. Total Mixed Ration (TMR) Complete feed → Roughage and concentrate are blended together, formulated to specific nutrient concentration, and fed free-choice The main advantages to TMR feeding are: Cows consume the desired proportion of forages when two or more forages are offered Cows consume the desired amount of forage relative to the amount of grain offered There is less risk of digestive upsets Feed efficiency improves There is potential to reduce labour required for feeding It allows for greater accuracy in formulating and feeding TMR Feeding →Video links https://www.youtube.com/watch?v=lS802qYRVMU https://www.youtube.com/watch?v=hOQLI0Di4is
- 17. Thumb Rule for Feeding Dairy Cattle Water 3 kg water for every kg of dry matter intake (winter and summer variation) 1.5 to 1.8 kg water for every kg milk produced DMI → 2.5 kg per 100 kg body weight Green fodder → 3 to 5 kg per 100 kg body weight Dry fodder → 1 to 2 kg per 100 kg body weight Concentrate For maintenance → 1.5 kg per day per cow (for indigenous crossbred cattle) First 2.5 kg milk produced → Maintenance ration is sufficient (1.5 kg per day per cow) > 2.5 kg milk produced → every kg milk produced 0.4 kg additional concentrate + M Pregnancy → Last trimester (>month of pregnancy) → (M + P + 1 to 1.5 kg per 100 kg bwt)
- 18. Summary In livestock rearing, 65-70% of the total cost is attributed to feeding Minimizing the expense towards feeding increases the profit Majority of diseases, reproductive problems and less milk production of the animals are related with the faulty nutrition of the animals Knowledge on newer ration balancing tools, identifying newer raw materials and knowing their nutritive value is important Ration formulation based on lab analyzed values rather than book values Feed according to their physiological state with balanced ration To achieve maximum genetic potential and optimum productivity → balanced feeding
- 19. Take home message To optimize productivity in large farms → grouping of animals according to their production state (2 or more groups) and feeding (2 or more rations) based on production is very important One calf per year Balanced nutrition/feeding is the key → profitable livestock production Genetics has created the potential, nutrition has failed to deliver that potential, “irrespective of the type of system practiced” Faster dissemination of ration balancing technology is essential
