The organization of animal feeding in the summer and
procurement of fodder for the winter are of great importance.
The sowings of sugar sorghum can become a
reliable and stable source of fodder even in the regions
with insufficient humidity. It is a unique drought tolerant
crop, which can be used as green mass, hay, silage,
grain, mono fodder, briquettes. The article gives the
study results of green mass and absolutely dry substance,
and the assessment of cultivation efficiency of such sugar
sorghum varieties and hybrids grown in FSBSI ‘I.G.
Kalinenko ARRIGC’ as ‘Zernogradsky yantar’, ‘Debyut’,
‘Listvenit’, ‘Zersil F1’, ‘Elisey F1’. The productivity
of green mass and dry substance of the new variety
‘Listvenit’ and the hybrid ‘Elisey’ exceeded the standard
variety on 7,0-5,0 t/ha and 2,30-0,74 t/ha respectively.
The cultivation technologies of sweet sorghum varieties
and hybrids produced the high net energy of 69,6-121,9
GJ/ha with the coefficient of energy efficiency of 3,72-
5,08. As for the energy, the cultivation technology of the
sweet sorghum hybrid ‘Elisey’ can be considered as the
most efficient variant, as it produced the maximum net
energy of 121,9 GJ/ha with the coefficient of energy efficiency
of 5,08
Sorghum is a source of concentrated, succulent and
coarse forage. Its grain is used for making the mixed
fodder and as the concentrated forage for swine, cows,
sheep, horses and poultry. Sweet sorghum is successfully
used for silage and haylage. Green chop of Sudan grass
is used as fresh food for domestic animals and it’s used
for making hay and silage. The nutritional value of the
fodder is the way to meet the animal needs in nutrients,
necessary for living. To determine the nutritional value
of the fodder, oat fodder units and energy fodder units or
exchange energy are used. At present the assessment of
nutritional value according to fodder units is being
revised, because it doesn’t give the true picture of the
value of fodder nutrition and animal needs in nutrients.
The general energetic nutritional value of fodder is
considered as contents of all organic substances, supplied
with fodder or with its energy. The nutritional value of
fodder is valued according to the characteristics of its
chemical composition, digestion of nutrients and general
(energetic) nutritional value. The purpose of the work is
to assess the nutritional value of fodder, obtained from
the best sorghum varieties, as the food for different kinds
of agricultural animals. Sorghum, used as fodder for
poultry possesses the largest nutritional value. Among
the grain sorghum varieties, the variety ‘Zernogradskoe
88’ has got the biggest value of fodder units. The green
chop of Sudan grass and green fodder for silage of sweet
sorghum possess the greatest nutritional value for swine.
The varieties of Sudan grass ‘Krasava’ and ‘Arkadiya’
and the variety of sweet sorghum ‘Listvenit’ are the best
varieties according to the contents of fodder units
