CHARACTERIZATION OF THE REPRODUCTIVE ACTIVITY OF SOWS BELONGING TO A MANGALITA SWINE POPULATION

V. Miclea, M. Zahan, Ileana Miclea

Abstract
The number of pigs belonging to the Mangalita breed is currently under rapid decline. As a consequence is the need for a conservation program presents itself. It should include the breed’s characterization from a morphological and productive point of view. Therefore, our aim has been to establish reproductive indexes for 25 sows belonging to a population kept at SUINPROD Roman. Research on these animals will continue, the final goal being to preserve it ex situ. Following bibliographical investigations we have concluded that an intensive rearing system reduces the age of the first mating to 9.2 months, the sows having 106.52 kg and the number of piglets is above breed average. The mean number of piglets increases from the first birth (7.96 piglets) to the third (8.46 piglets) without any negative influence on their weight which is between 1.0 – 1.04 kg. Mortality rates are the highest for young sows (13.56%) decreasing steadily as the animals get older. With optimum rearing and feeding piglets are weaned at 30-32 days. The total weight of the piglets at weaning rises, due to improvement in sow ability to feed them.

CARACTERIZAREA ACTIVITATII DE REPRODUCTIE A SCROAFELOR APARTINĀND UNEI POPULATII DE SUINE DIN RASA MANGALITA

Rezumat
Mangalita este una din rasele autohtone de suine a caror efective se reduc numeric īn ritm rapid. Conservarea se impune ca si o consecinta a situatiei mentionate fiind o activitate complexa care include si cercetari privind caracterizarea rasei din punct de vedere morfo-productiv. Pornind de la aceste considerente ne-am propus sa determinam principalii indici de reproductie la un efectiv de 25 scroafe si scrofite provenite dintr-o populatie crescuta la SUINPROD Roman. Acest material biologic se va utiliza īn alte lucrari de cercetare care vor urmari conservarea ex situ a rasei. Īn urma efectuarii investigatiilor apreciem ca asigurarea conditiilor de īngrijire si hranire caracteristice tehnologiei intensive tineretului femel Mangalita reduce la 9,2 luni vārsta primei monte fecunde scrofitele ajungānd la 106,52 kg. De asemenea numarul purceilor la prima fatare este peste media rasei. Numarul mediu al purceilor creste de la prima (7,96 capete) la fatarea a treia (8,46 capete) fara a influenta negativ greutatea lor corporala care este cuprinsa īntre 1,0 – 1,04 kg. Mortalitatea purceilor din perioada de alaptare este maxima la scrofite (13,56%), dupa care scade treptat. Īntarcarea purceilor se poate realiza la 30-32 zile īn conditiile de crestere si furajare optime. Greutatea totala a lotului de purcei la īntarcare are o dinamica ascendenta demonstrānd īmbunatatirea treptata a capacitati de alaptare a scroafelor.
