Abstract
The research findings on the productive characteristics in the “Balotesti” eggs-meat quail population raised and selected at „S. C. Nova Farm S.R.L.” Bucharest, upon an initial number of 2,000 quails, studied individually or on cage, in function of the productive characteristic, indicated that the average body weight at the age of 42 days was of 205.3 g and the daily average weight gain in the period of 1-6 weeks of raising was of 4.65 g, the daily average feed consumption and the specific consumption was of 15.63 g, respectively 3.46 g and the viability was of 90.5 %. In the first 48 weeks of the laying period of the quails raised for reproduction, it was obtained an average laying percent of 63.03, the daily average feed consumption and the average specific consumption being of 37.35 g, respectively 68.25. The daily consumption for the 1-6 weeks period of raising the youth quails was of 46.53 kcal ME and 3.30 g crude protein. In 48 weeks of laying the daily consumption was of 103.72 kcal ME and 7.32 g crude protein. The performances are superior to other populations in our country, raised in majority only for eggs, and similar to that exploited in others countries with tradition in quail raising, being suited to continue the selection in the direction of obtaining lines specialized for eggs or as broiler mother.

STUDIU PRIVIND CARACTERISTICILE PRODUCTIVE ALE TINERETULUI SI PREPELITELOR OUATOARE DIN POPULATIA MIXTA DE OUA-CARNE “DE BALOTESTI”

Rezumat
În urma cercetarilor efectuate pentru stabilirea caracteristicilor de productie ale prepelitelor din populatia de „Balotesti” crescuta si selectionata la „S.C. Ferma Nova S.R.L. Bucuresti” pe un numar initial de 2000 prepelite, urmarite individual sau pe cusca, în functie de parametrul productiv, s-a determinat ca greutatea vie medie la vârsta de 42 de zile si sporul mediu zilnic în primele 6 saptamâni de crestere a fost de 205,3 g, respectiv de 4.63 g/cap/zi, consumul mediu zilnic de furaje si consumul specific fiind de 15,63 g si, respectiv, de 3,46 iar viabilitatea a fost de 90.5 %. În primele 48 de saptamâni de ouat ale prepelitelor, crescute pentru reproductie, s-a obtinut un procent mediu de ouat de 63,03 %, consumul mediu zilnic de furaje si consumul specific mediu fiind de 37.35 g, respectiv de 68.25 g. Consumul de energie si proteina la tineret pentru perioada 1-6 saptamâni de crestere a fost de 46.53 kcal, respectiv 3.30 g proteina bruta. În 48 de saptamâni de ouat, consumul de energie metabolizabila si proteina (pe cap/zi) a fost de 103.72 Kcal EM si, respectiv de 7,32 g proteina. Performantele sunt superioare populatiilor de prepelite din tara noastra, care se cresc în majoritate doar pentru oua si apropiate de cele exploatate în alte tari cu traditie în cresterea acestei specii, pretându-se pentru continuarea selectiei în directia obtinerii de linii specializate pentru oua sau ca mama de broiler.
