RESEARCH ON BODY DEVELOPMENT DYNAMIC OF CARABASH LAMBS IN SUCKLING PERIOD

Cristina Lazar, Rodica Pelmus, Elena Ghita

Abstract
Our research conducted in the experimental farm of INCDBNA Balotesti monitored the evolution of Carabash lambs body weight from lambing to weaning, with the purpose to determine the performance of this breed to produce milk lambs, compared to other sheep breeds reared in Romania. The average live weight of the lambs from simple lambing was 5.40 kg for the male lambs and 5.08 kg for the female lambs. The average live weight of the lambs from twin lambing was 4.88 kg for the male lambs and 4.65 kg for the female lambs. At the age of one month, the male lambs from simple lambing weighed in average 15.65 kg, while the male lambs from twin lambing weighed in average 12.33 kg. At the same age, the female lambs from simple lambing weighed in average 14.51 kg, while the female lambs from twin lambing weighed in average 10.94 kg. At weaning (2 months) the male lambs from simple lambing weighed in average 23.15 kg, while the male lambs from twin lambing weighed in average 18.031 kg. The female lambs from simple lambing weighed in average 22.32 kg, while the female lambs from twin lambing weighed in average 17.38 kg. The average daily weight gain was 296 g for the male lambs from simple lambing and 219 g for male lambs from twin lambing. Prolificacy of Carabash sheep was 152%. The analysed parameters recommend this breed mainly for meat production, but also for milk production.

Key words: suckling period, body weight, average daily gain, prolificacy

Rezumat
Īn cadrul cercetarii noastre efectuate īn ferma INCDBNA Balotest am urmarit evolutia greutatii corporale a mieilor din rasa Carabasa de la fatare si pāna la īntarcare pentru a evidentia performanta acestei rase comparativ cu celelalte rase de ovine din tara noastra pentru producerea de miei de lapte. Media greutatii vii la fatare a mieilor masculi proveniti din fatari simple a fost de 5,40 kg, iar la femele de 5,08 kg. Mieii masculi proveniti din fatari gemelare au īnregistrat o medie a greutatii corporale la nastere de 4,88 kg, īn timp ce femelele au avut 4,65 kg. La vārsta de o luna masculii din fatari simple au prezentat o medie a greutatii corporale de 15,56 kg, iar cei proveniti din fatari gemelare o medie de 12,33 kg. La aceeasi vārsta femelele din fatari simple s-au evidentiat cu o greutate medie de 14,51 kg, iar cele din fatari gemelare au prezentat o greutate medie de 10,94 kg. La īntarcare (2 luni) mieii masculi din fatari simple au atins o greutate medie de 23,15 kg,iar cei din fatari gemelare au avut ogreutate medie de 18,031kg.Femelele din fatari simple au inregistrat o greutate medie de 22,32 kg,iar cele din fatari gemelare17,38 kg. Sporul mediu zilnic obtinut a fost de 296 g la masculii din fatari simple si de 219 g la cei din fatari gemelare. Prolificitatea obtinuta la ovinele Carabasa din populatia analizata a fost de 152 %.Parametrii analizati recomanda aceasta rasa pentru productia de carne īn principal dar si pentru cea de lapte.
