Conducted research on the chemical composition and nutritional value of haylage from a mixture of triticale and vetch. The optimal ratio of components of triticale in the mixture with vetch in haylage, ensuring maximum yield of nutrients per unit area was set.

In recent years in Ukraine problem of feed protein – one of the main in fodder production. Overrun feed per unit of livestock production primarily related to low-digestible protein in fodder units and imbalance in fodders for other nutrients.

Therefore, increasing the production of high quality ensilage fodder, and feed and fodder grain is one of the important problems of agriculture, these problems decisions should be solved by the full improvement of production technology with current science achievements and best practices.

In order to create a stable fodder base, increasing the volume of livestock production and improve its quality, high-yielding forage crops are used for the production of green fodder, silage, haylage, hay. But it is not take into account the priority of these crops on land use efficiency, reduce energy costs, labor and material resources.

In this regard, it is important to study the chemical composition and nutritional value of haylage containing the mixture of triticale and vetch and efficiency of its use in the fodders in the steppe zone of Ukraine.

So, the objective of the research is to substantiate the effectiveness of the harvesting of ensilage fodder mixed with green mass grass-legume mixture which includes triticale vetch.

According to the objective the following tasks were set:

– to examine the chemical composition, nutritional value of haylage mass in different ratios for silage;

– to determine the content of organic acids of haylage mass of triticale and vetch mixture;

– to give organoleptic assessment of silage fodders mixed with green mass grass-legume mixture.

Experimental work was conducted in the educational farm "Trofimova" Ovidiopil district of Odessa region. Laboratory studies on organoleptic and chemical composition of haylage were performed in the Yampolsk laboratory of veterinary medicine in Vinnytsia region.

During the research it was studied the optimal ratio of components of triticale in the mixture with vetch in haylage, ensuring maximum yield of nutrients per unit area.

As the basic component during silage harvesting we used green mass grass-legume mixture which includes triticale vetch. Filled laboratory glassware was opened after 210–220 days of keeping then nutritional study of organoleptic characteristics and chemical composition of haylage was conducted.

Chemical analysis of canned fodder green mass of triticale and vetch mixture collected in the flowering stage showed that the highest amount of protein, fat, calcium, carotene and less fat is stored in clean winter vetch crops compared with a pure crops of winter triticale.

Mixed crops with the use of triticale contain protein and carotene in 1.5–2.0, phosphorus and calcium in 1.5–3 times more and fiber 10–20 % less than in pure triticale. Increasing the ratio of triticale to vetch it is noted some reduction in protein and carotene. Most high-quality haylage is received by the ratio triticale to vetch 50:50 60:40 %. These mixtures contain the maximum amount of digestible protein per kilogram of fodder.

The results of organoleptic assessment and chemical analysis of the content of free acids showed that pure legume haylage with vetch fermentation processes occur slowly pH of haylage is high 5.6–5.8 at humidity 47–50 %.

Organic acids where 30–33 % are acetic accumulate in haylage. At this humidity anti nutrients of vetch are inhibited.

In grain-vetch haylage at 48–53 % moisture fermentation processes were more intense. 65–71 % of lactic acid, 27–29 % acetic acid and 0.22–0.24 % of butyric acid were accumulated in the fodder.  

Thus, the above data on quality characteristics and nutritive value of triticale-vetch haylage mixture allow to prove that this fodder can be used for feeding cattle.
