RESEARCH ON SEMIINTENSIVE FATTENING SYSTEM OF HYBRIDS OBTAINED BY INDUSTRIAL CROSS BREED OF PALAS MERINO WITH SPECIALIZED MEAT SHEEP BREEDS PUBLISHED

P. G. VICOVAN, Daniela JITARIU, Maria STANCIU
Researches aimed the increasing and improving of the quantitative and qualitative sheep meat,the meat skills production determination of hybrids obtained by industrial cross breed of Palas Merinowith breeds specialized in meat production- Texel and Suffolk. The experiments were performed at theInstitute for Research and Development Institute for sheep and goat breeding Palas-Constanta and thebiological material was represented by: adult sheep, 3 lots - 3 x 50 head., F1 crossbred lambs resultingfrom the crossing specialized meat breed rams Suffolk and Texel with Merino sheep breed, n = 2 x 25heads; control lot consisting of young male Merino sheep breed, n = 1 x 25 head. Weighing lambs atbirth was performed at 28 days and at weaning (60 days), registering growth in weight made throughoutthe period and per day. After weaning, young sheep was introduced to fattening, it was weighed at thebeginning and the end of each phase of fattening, calculating the total gain and average daily gain perperiods and per each phase separately. When fattening youth achieved average body weight of 35 kg, itwas considered a complete fattening period and control slaughter were performed for each experimentalvariant and for the control group. Statistical parameters were calculated, Fisher test was applied. Byindustrial cross breed it has been obtained an improvement of growth rate, precocity and specificconsumption.
