🐄 Livestock Health & Production Guide
Science-based tools for the health and productivity of your cattle, sheep, goats and other livestock. Reproduction, nutrition, health and economic analysis combined.
Gestation & Calving Calendar
Calculate estimated calving date from insemination date. Species-specific gestation periods and critical periods for cattle, sheep, goats, horses and pigs.
Colostrum Management
Calculate the vital colostrum amount for newborn calves, lambs and kids. Adequate colostrum intake within the first 6 hours is critical for immunity.
Calculate ColostrumLive Weight Estimation
Estimate live weight using heart girth and body length measurements without a scale. Scientific formulas for cattle, sheep and goats.
Milk Yield Analysis
Calculate 4% FCM (Fat-Corrected Milk) to compare milk at different fat levels. Measure profitability over feed cost with IOFC.
Fattening Performance (ADG)
Calculate average daily gain (ADG) and feed conversion ratio (FCR). Evaluate fattening performance and estimate time to reach target slaughter weight.
Heat Stress Index (THI)
Assess your animals' heat stress risk based on temperature and humidity. Milk yield drops above THI 72, serious health risks start above 78.
Calculate THIDrug Withdrawal Period
Calculate withdrawal periods of antibiotics and other veterinary drugs in meat and milk. Compliance with legal waiting periods is critical for food safety.
Economic Analysis
Measure your farm's profitability with breakeven analysis and dairy economics. Cost-revenue analysis, scenario comparison and VetKriter Brain assessment.
Ration Calculation Tools
Meet your animals' nutritional needs with NRC-compliant ration calculation tools.
