Cattle rations calculation

The software product “NIVA-Ration” is supposed to automate compiling of cattle feed rations and was developed by the “LICC Minagriculprod” UE in association with the “SPC of Livestock breeding” RUE (Zhodino) by order of the Ministry of agriculture and food products. As the basis for this software product’s development a modern theory of cattle feeding was provided, taking into consideration physiology of animals which is based on the animals satisfaction of wants not for food units but for energy units.

The software package can be used by experts who compile cattle feed rations – selection of feed and feed ingredients, their weighing and appraisal of the ration cost. The program scans not only optimal types of rations that can satisfy physiological needs of the cattle and their maximum productivity, but also suggests economically the most appropriate variants.

Calculation of the feeding ration is made for milking herds and young cattle, taking into consideration physiological phases of the growth. Thus, the following periods are considered for a milking herd:

  • Increasing the milk yield 45 days (upon weeks of lactation)
  • Freshly calved period 46-100 days
  • Midlactation 101-200 days
  • End of lactation  201-305 days
  • Far off dry period for 39 days
  • Preparation period for 21 days – i.e. covers the whole calendar year.

Besides, during calculation of the ration it’s necessary to take into consideration an animal’s weight and its yielding capacity (for milk cows it is a milk yield, its fatness and protein; for animals in farming and fattening it is a daily weight gain).

While planning the ration first of all it’s necessary to calculate needs of the chosen animal group (in a certain phase of growth) in quality indicators, whose values depend on the physiology of animals:

  • Requirement of Net Energy of Lactation (for support of existence and production of outputs)
  • Requirement of Usable Crude Protein (for support of existence and production of outputs)
  • Requirement of feed dry matter

Hereafter, depending on the chosen fodder and index correlations, determined by scientifical methods, quantitative and qualitative compositions of the ration are calculated. Proposed index correlations, their minimum and maximum doses for every phase of animal growth are shown in the reference books and can be corrected by the User as and when necessary.

The User chooses a criterion of defining optimum of the ration at the stage of the exact ration’s calculation.

If it's necessary to add some concentrated feeding stuff, the program makes opportunity to estimate a feed formula with defined quality indexes.

The software package is supplied with a unique in its completeness catalogue of feeding stuff with detailed indications of every position's quality indexes. The catalogue can be enlarged and corrected so far as necessary on the ground of the data received during laboratory studies of the feed.

The software solution allows accomplishing of target-focused (differentiated) feeding of the cattle.
