Abstract:
The researches which are the present work paper object was
performed to I.C.D.O.C. Palas – Constanta, it was used like biological
material 20 sheep from Palas milk production specialized population,
maintain in permanently stabulation by 215 days. During the performed
researches the sheep given feed ration had used the volume forage (maize
forage silo whole plant harvesting to the milk-wax stage and Lucerne hay)
and concentrate forage (maze grains and soy oil meal). Based on calculated
forage standards depending on sheep physiological stage, it was made the
feed rations for each individually category. Based on crude chemical
composition and on the digestibility coefficients from specialized literature, it
had calculated the nutritive value of the forages, which are included in sheep,
feed rations. In order to emphasizing the capitalization percent of given food
for dairy production, it has calculated sheep feed consumption during the
lactation: dry matter, energy, protein, calcium and phosphorus consumption
/sheep/day, dry matter consumption/100 kg live weight and dry matter
consumption/metabolic weight, energy and protein consumption/milk litre
and on dry substance kilo from milk, energy and protein consumption/fat and
protein kilo from milk. Nutritive matter consumption/sheep/day and for milk
and for its components synthesis too, has values which show an efficient and
constant utilization of energetic substances (expressed by UNL) but
especially of protein substances from forages (expressed by PDIN and PDIN)
by animal body used for milk production.
