Pastocare is a direct-fed microbial, vitamin and mineral supplement developed for sheep and goats. It is used to complement the daily ration by supporting digestive microbial balance, nutrient utilization, normal growth, reproductive performance and overall animal condition. How does Pastocare benefit sheep and goats? Pastocare supplies beneficial microbial cultures together with vitamins A, D3 and E and selected trace-mineral sources. These nutritional components help support digestive function, nutrient metabolism, healthy development, reproductive function and the animal’s natural immune defences. Product performance will depend on the quality of the total diet, forage availability, animal health and farm-management conditions. Is Pastocare suitable as a feed supplement for sheep? Yes. Pastocare is designed for use as one of the feed supplements for sheep and contains no intentionally added copper. It should nevertheless be used as part of a properly balanced feeding programme because sheep are sensitive to inappropriate mineral supplementation. The complete ration should be reviewed to account for minerals already supplied through forage, concentrates, water and other supplements. Can Pastocare improve feed conversion efficiency? Pastocare may support more efficient feed utilization by helping maintain digestive microbial balance and supporting normal nutrient metabolism. However, feed conversion efficiency is also influenced by feed quality, forage digestibility, genetics, animal health, environmental conditions and general herd management. Pastocare should therefore be positioned as nutritional support rather than as a guarantee of a specific feed-conversion result. Is Pastocare suitable for regular use? Pastocare can be incorporated into a regular feeding programme when used according to the approved product label and as part of a nutritionally balanced ration. Before combining it with other vitamin or mineral products, review the total dietary intake to avoid unnecessary duplication or excessive supplementation. For specialised breeding, pregnancy, lactation or intensive growth programmes, consult an animal nutritionist or veterinarian. Dosage & Application Pastocare is intended for inclusion in the daily feeding programme of sheep and goats. Mix the recommended quantity thoroughly with compound feed, concentrate, total mixed ration or another suitable feed material to ensure uniform distribution throughout the ration. The appropriate inclusion rate should be determined according to: Animal species and body weight Age and stage of production Growth, breeding, pregnancy or lactation requirements Existing vitamin and mineral content of the diet Forage quality and local feeding conditions Always follow the dosage stated on the approved product label or the recommendation provided by an animal nutritionist, veterinarian or IndoGulf BioAg technical representative. Provide animals with continuous access to clean drinking water. Avoid combining Pastocare with other highly fortified vitamin or mineral supplements unless the complete ration has been reviewed. Additional Info Product type: Direct-fed microbial, vitamin and mineral feed supplement Target animals: Sheep and goats Application method: Mixing with the daily feed ration Formulation: Beneficial microbial cultures combined with vitamins and trace-mineral sources Pastocare is formulated to complement balanced small-ruminant nutrition. Its microbial cultures help maintain a balanced digestive environment, while the included vitamins and minerals support normal growth, nutrient metabolism, reproductive function and immune-system performance. The product contains no intentionally added copper. Because the mineral requirements of sheep and goats may differ, the total copper, molybdenum, sulphur, iron, selenium and other mineral content of the complete diet should be considered before use. Pastocare is a nutritional feed supplement and is not a substitute for good-quality forage, balanced feed, proper veterinary care or effective herd-management practices. Storage and Handling Store in a cool, dry and well-ventilated location, away from direct sunlight, excessive heat and moisture. Keep the package tightly closed after opening to protect the microbial cultures and maintain product quality. Always use clean, dry equipment when measuring or handling the product. Keep out of reach of children. Use only as an animal feed supplement.

Sulfur Oxidation Pathway Primary Biochemical Mechanism: Acidithiobacillus thiooxidans employs a multi-enzyme network to oxidize reduced inorganic sulfur compounds (RISCs) into sulfate. Elemental Sulfur Oxidation: Initiation enzyme: Sulfur dioxygenase (SDO; EC 1.13.11.18) Reaction: 2S⁰ + 3O₂ + 2H₂O → 2H₂SO₄ Rate: 2-8 mg S/g dry biomass/day (soil conditions); up to 100 mg/L in culture pH change: Gradual reduction from neutral to acidic conditions Intermediate Sulfur Oxidation: Thiosulfate oxidation: Involves thiosulfate dehydrogenase and tetrathionate intermediate formation Polysulfide oxidation: Direct oxidation of polysulfide chains Sulfite oxidation: Complete oxidation via sulfite oxidase enzymes Energy Generation: The oxidation reactions serve as the exclusive energy source for A. thiooxidans, powering ATP production through electron transport chain mechanisms: Electrons derived from S⁰ oxidation flow through cytochrome complexes Oxidative phosphorylation generates ATP for biosynthetic processes CO₂ fixation via the Calvin cycle provides organic carbon from atmospheric CO₂ 2. Acidification Mechanism Sulfuric Acid Production: The complete oxidation of elemental sulfur to sulfate produces sulfuric acid, which dissociates in soil solution: H₂SO₄ → 2H⁺ + SO₄²⁻ pH reduction: Typically 7.0-8.0 (alkaline) → 5.5-6.5 (slightly acidic) Localized vs. bulk: Bacterial aggregation creates micro-acidic environments around sulfur particles Controlled Acidification Advantage: Unlike rapid chemical acidification (e.g., adding mineral acids), biological sulfur oxidation provides: Gradual pH change preventing root damage Localized acid production concentrated around sulfur particles Sustained effect throughout growing season pH regulation prevents over-acidification through buffering interactions with soil minerals Soil Buffering and Sustainability: The acidification process continues as long as elemental sulfur particles remain available and moisture and oxygen conditions are adequate. In alkaline soils, acid production is partially neutralized by carbonate reactions: CaCO₃ + H₂SO₄ → CaSO₄ + H₂O + CO₂ Net effect: Sustained pH reduction despite buffering capacity 3. Nutrient Mobilization Mechanisms Primary and Secondary Micronutrient Release: Iron Mobilization: Lowered soil pH converts insoluble ferric hydroxide (Fe(OH)₃) to soluble ferrous iron (Fe²⁺) Ferrous iron is readily absorbed by plant roots and transported through vascular tissues pH-dependent availability: Each 1.0 pH unit decrease increases Fe availability 10-100 fold Zinc Mobilization: Zinc silicates and oxides become soluble at pH <7.0 Complexation with organic acids (produced during sulfur oxidation) further enhances Zn bioavailability 25-40% increase in Zn concentration in soil solution Manganese and Copper Mobilization: Similar pH-dependent solubility increases Chelation effects from organic acids enhance bioavailability 20-35% increase in plant-available micronutrients Phosphorus Availability: Improved soil pH reduces phosphate fixation by iron and aluminum oxides Secondary effect improving overall nutrient balance 4. Biofilm Formation and Rhizosphere Colonization Biofilm Architecture: A. thiooxidans forms biofilms on elemental sulfur particles and soil mineral surfaces, enhancing sulfur oxidation efficiency: Extracellular polymeric substances (EPS): Polysaccharides and proteins trap water and nutrients Cell aggregation: Biofilms can reach 10⁸-10⁹ CFU per gram of biofilm Oxygen gradient management: Biofilm structure enables anaerobic bacterial zones with access to oxygen at biofilm surface Nutrient concentration: Localized nutrient accumulation in biofilm matrix Rhizosphere Persistence: Colonization density: 10⁶-10⁸ CFU per gram of rhizosphere soil Persistence period: 8-16 weeks under favorable conditions; periodic re-inoculation recommended for sustained benefit Root surface colonization: Bacteria attach to root epidermis; hyphal invasion not observed (non-pathogenic) 5. Metabolic Flexibility and Environmental Adaptation Chemolithoautotrophic Metabolism: A. thiooxidans survives on inorganic substrates exclusively: Energy source: Elemental sulfur or sulfide minerals Carbon source: CO₂ (fixed via Calvin cycle) Electron acceptor: Oxygen (aerobic); some studies suggest ferric iron under oxygen-limited conditions Nutrient requirements: Minimal (nitrogen, phosphorus, trace metals) Acid Tolerance Mechanisms: pH homeostasis: Internal pH maintained at ~6.0-6.5 despite external pH <2.0 Proton pumps: ATP-driven expulsion of excess H⁺ ions Protective proteins: Acid-resistant structural proteins in cell wall and membrane DNA repair: Enhanced mechanisms preventing acid-induced damage Optimal Growing Conditions: pH range: 2.0-7.0; optimal 3.0-5.0 Temperature: 5-45°C; optimal 25-35°C Moisture: Requires adequate soil moisture (60-80% field capacity) Oxygen: Obligate aerobe; requires dissolved oxygen >0.5 mg/L Nutrient availability: Nitrogen, phosphorus, trace metals required for biosynthesis Additional Info Recommended Crops: Cereals, Millets, Pulses, Oilseeds, Fibre Crops, Sugar Crops, Forage Crops, Plantation crops, Vegetables, Fruits, Spices, Flowers, Medicinal crops, Aromatic Crops, Orchards, and Ornamentals.
