Object of research – bull-calves
Kazakh white-head breed of large horned livestock planted in the west of
Kazakhstan.
The aim of the research – The quality of the constituent bodies of offal in
the process of intensive fattening of bulls, the growth of their mass and
improve the quality of raw meat products.
Research methods: Feeding and meat
qualities, a chemical compound of compound bodies of an offal, young growth of
large horned livestock were defined by technique VASHNIL (1983), VNIIZH (1968),
factors of growth of bodies were studied by R.T.Berg, R.M.Batterfild's
technique (1979). Marketability of the hulk, lethal qualities, an organoleptic
estimation of meat products were defined on GOST 5110-55 and 9959-91. Biometric
processing of digital materials was spent by N.A.Plohinskij's technique (1980).
Results of research. At 100-day
fattening bull-calves with use local and nonconventional (grain of safflower)
forages owing to intensive growth of the hulk (in 1,24-1,41 times) and internal
fat (1,48-2,56 times), an offal ²² categories have
slightly decreased from 10,7% to 10,2-10,4%.
In process of
fattening at bull-calves ²² the skilled group,
using grain of safflower, growth of an offal ² and ²² categories occurs more
intensively (1,38 and 1,32 times), than at bull-calves ² the skilled group, eating only local forages and
control group of the bull-calves fattened in economic conditions (1,21-1,30 and
1,19 - 1,25).
For the period of
fattening at bull-calves among the bodies which are a part of an offal ² of a category, higher intensity the liver
(1,03-1,09), a diaphragm (0,91-1,01), meat-bone a tail (0,94-0,98) and low -
brains (0,90-0,93), language (0,89-0,91) and kidneys (0,77-0,90) differed.
Growth of these bodies (except kidneys) at bull-calves ²² skilled group occurs more intensively, than at
contemporaries ² skilled, especially from
control group.
In process of
fattening young growth LHL (large horned livestock) among the bodies which are
a part ²² of a category of an offal,
more intensive growth the hem, ears, lips (1,01-1,03), and rate of growth of
the book differed, abomasums it
has appeared low (0,77-0,87). At bull-calves ²² groups intensity of growth of abomasums (0,97
against 0,90), lips (1,23 against 1,09) and ears (1,09 against 1,05) it has
appeared high, and spleen growth (1,03 against 0,84), a gullet (0,91 against
0,86) - low, than at bull-calves from ² skilled group.
Power value of the
bodies which are a part ² of a category,
especially at a liver, kidneys, tail and diaphragm meat-bone has appeared high
at bull-calves ²² groups, than at
contemporaries from ² skilled,
especially from control group.
At bull-calves ²² skilled group in bodies ²² categories of an offal (on 0,8-2,1 units above)
especially in abomasums, a hem, ears, head pulp (on
1,5-2,1 units above) the fat maintenance was above, than at contemporaries ² skilled group.
In the course of
intensive cultivation and îòêîðìà the gain of an
offal at increase of live weight of bull-calves with 225 to 260 kg has made 5,1
kg, with 260 to 295 kg – 5,5 kg and with 295 to 330 kg – 2,3 kg, that is last
periods of preparation of bull-calves on meat the gain of an offal in
connection with intensive growth of weight of the hulk has decreased. The gain
of an offal ² categories with increase of
weight categories was in limits of 0,81-1 kg, and ²² categories–1,8-4,6 kg. In this connection the exit ² and ²² categories of an
offal with increase of weight categories of bull-calves has a little decreased
according to 3,5% and 10,7% to 3,1 and 10,2 %.
New sausages and
canned food made from offal I and II categories, obtained from slaughter taken
from fattening bulls with aromatic herbs, have received high ratings (4,2-4,4
points), which indicates the possibility of full utilization the production of
meat products.
The basic constructive,
technological and tehniko-operational characteristics. On the basis of studying of dynamics of growth of
weight and quality of the bodies which are a part of an offal of bull-calves in
process, local and nonconventional forages and manufacturing from them meat
products reveal more effective methods of improvement of quality of an offal
and meat products.
The recommendation about
introduction or results of introduction of research work. Results of
research work are recommended to be used in the economy which are engaged in
cultivation of large horned livestock both the processing enterprises and
shops.
Economic entities
of different forms of ownership, distributing cattle and processing enterprises
and shops.
Intensive fattening
young growth of large horned livestock with use of local and nonconventional
forages (safflower’s grain) promotes reception from 1 head of bull-calves
12888-15782 tenges of profit at profitability of 25,5-36,6 %.
With intensive
fattening bulls II in the experimental group compared with their peers from ² experimental and control groups received respectively
from 1 head 641 and 2,894 tenge, with an offal - 221 and 448 tenge profits.
Intensive fattening
bull-calves aulieatin breeds, with use of local and nonconventional forages,
promotes finishing of a daily average gain of animals with 690-720 ã to 1010-1060 ã, to an exit of the
hulk with 50,4% to 52,3%; growth of weight of an offal with 34,6 kg to 46,1 kg,
and to improvement of quality of an offal ² and ²² a category the sausage products made of them and
canned food.
