ALGORITHM FOR APPLICATION OF COMPLETE RATIO COMBINED FEED UNDER CONDITIONS OF INTENSIVE RABBIT PRODUCTION

Abstract

The article contains materials on the calculation of recipes for full-ration compound feed for conditions of intensive production of rabbit meat, built on the use of the Microsoft Excel program. The norms approved by the 8th International Congress on Rabbit Breeding (2004) are used as the basis for rationing rabbit
feeding. The recipes do not use feed of animal origin. The compound feed recipes are designed for young animals aged 18-42 and 42-70 days, adult breeding herds under conditions of intensive reproduction (more than 50 rabbits per queen during the production year), semi-intensive (less than 40 rabbits), as well as a single feed for all age groups of rabbits. Rationing was carried out according to the content of
the rabbits' metabolic energy, crude protein, crude fat, crude fiber, lysine, methionine + cystine, threonine, tryptophan, calcium, phosphorus, sodium, potassium, magnesium and sulfur. Enrichment compound feed with amino acids, vitamins and trace elements occurred due to the use of a premix.
It was established that the most "concentrated" nutrition was characterized by the feed for feeding the main herd during intensive breeding, which was achieved due to the increased amounts of soy cake and sunflower introduced into the recipe. In semi-intensive breeding (less than 40 rabbits per female rabbit), the
same recipe contained less exchangeable energy - on 3.0%, crude protein – by 3.4%, crude fat – by 6.0%, lysine – by 6.1% and threonine – by 1.5%.
The nutritional content of a single universal feed for all age groups was: exchangeable energy - 9.9 MJ, crude protein - 162.9 g, crude fat - 38.8 g, crude fiber - 149.7 g, lysine - 7.8 g, methionine + cystine – 6.2 g, threonine – 6.5 g, tryptophan – 2.2 g, calcium – 11.2 g, phosphorus – 5.0 g, sodium – 2.1 g, potassium – 7.5 g, magnesium – 3.0 g and sulfur – 2.2 g. Its nutritional value is lower than for feeding brood stock during intensive reproduction: in terms of exchangeable energy – by 4.8%, in terms of crude protein – by 2.1%, by crude fat tryptophan – by 4.3%, calcium – by 6.7 %, phosphorus – by 10.7% and sulfur – by 47.6%.
The results of research on the development of recipes for full-rational granulated compound feed according to international standards with intensive rabbit meat production technology have shown the possibility of using Excel calculation tables, which, in turn, gives specialists free access to relevant calculations without the use of expensive specialized programs. The development of recipes can be carried out in Excel both on personal computers and on tablets or smartphones running on Android. Such recipes of compound feed without the introduction of ingredients of animal origin can be used on rabbit farms in conditions
of intensive production, which, in turn, will contribute to the improvement epizootic
situation and increase of quality indicators of meat.
