Animal science studies the biology of animals. Animal nutrition, animal breeding, animal structure and function, animal agribusiness, and animal reproduction are some of the topics that are covered in the development of tools in animal science.

iLactating Sow Minerals Version 1.0

Given the liveweight(kg), obligatory losses (calcium, g/100 kg W), milk production per day(kg), amount of calcium in the milk (g/kg), and gross efficieny of utilisation of calcium, iLactating Sow Minerals Version 1.0 estimates the calcium requirement(g/kg). The tool also plots the variation of calcium requirement(g/kg) against the liveweight(kg).

iPerformance Growing Cattle Version 1.0

iPerformance Growing Cattle Version 1.0estimates the liveweight gain of a ration given the food intake (kg), dry matter (DM, g/kg), metabolisable energy of the food (ME, MJ/kg DM), concentrate intake(kg), concentrate dry matter (DM, g/kg), metabolisable energy of the concentrate (ME, MJ/kg DM), energy requirements for maintenance(MJ NE/day), and energy requirements for liveweight gain(MJ/kg gain). iPerformance Growing Cattle Version 1.0 also plots the variation of liveweight gain(kg) against the food intake(kg).

iRation Con Version 1.0

iRation Con Version 1.0estimates the amount of concentration of a ration given the food intake (kg), dry matter (DM, g/kg), metabolisable energy of the food (ME, MJ/kg DM), concentrate dry matter (DM, g/kg), metabolisable energy of the concentrate (ME, MJ/kg DM), energy requirements for maintenance(MJ NE/day), and liveweight gain(kg gain). iRation Con Version 1.0 also plots the variation of concentration intake(kg) against the food intake(kg).

iCost Version 1.0

iCost Version 1.0estimates the total cost of a ration given the food intake unit price(USD/kg), concentration intake unit price(USD/kg), food intake (kg), dry matter (DM, g/kg), metabolisable energy of the food (ME, MJ/kg DM), concentrate dry matter (DM, g/kg), metabolisable energy of the concentrate (ME, MJ/kg DM), energy requirements for maintenance(MJ NE/day), and liveweight gain(kg gain). iCost Version 1.0 also plots the variation of total cost(USD) against the food intake(kg).

iRation Version 1.0

iRation Version 1.0estimates the amount of food intake(kg) and concentrate intake(kg) of a ration given the total intake(kg DM/day), milk yield(l/day), protein content of the milk(g/kg), fat content of the milk(g/kg), dry matter (DM, g/kg), metabolisable energy of the food (ME, MJ/kg DM), concentrate dry matter (DM, g/kg), metabolisable energy of the concentrate (ME, MJ/kg DM), energy requirements for maintenance(MJ NE/day), and efficiencies of utilisation of metabolisable energy for maintenance and milk production. iRation Version 1.0 also plots the variation of food intake(kg) against the total intake(kg DM/day).

iMilky Version 1.0

iMilky Version 1.0estimates the gross energy of milk(MJ/kg) given the milk protein content(g/kg), gross energy of protein(MJ/kg), milk fat content(g/kg), gross energy of fat(MJ/kg), milk carbohydrate content(g/kg), and gross energy of carbohydrate(MJ/kg). iMilky Version 1.0 also plots the variation of gross energy of milk(MJ/kg) against the milk fat content(g/kg).

iMetabolisability Version 1.0

iMetabolisability Version 1.0estimates the metabolisability of a ration given the food intake (kg), dry matter (DM, g/kg), metabolisable energy of the food (ME, MJ/kg DM), concentrate intake(kg), concentrate dry matter (DM, g/kg), and metabolisable energy of the concentrate (ME, MJ/kg DM).
