Carcass Characteristics of Purebred Tsurcana Lambs and F1 Crossbreds (Tsurcana X Vendeen)

The data presented in this article is included in a larger research regarding the improvement of the Romanian lamb towards the meat production. The study has been carried out from 2015 to 2016. The lambs included in this study were obtained following a protocol of estrus synchronization in Tsurcana ewes and the grouped lambing. The research is a pilot study conducted on a representative sample for the selected groups of animals and further research is needed to complete the research. The research aims to compare carcass characteristics of purebred Tsurcana lambs and Tsurcana crossed with Vendeen lambs. The criteria assessed were: the chemical composition of purebred and crossbred meat, the live body weight, the slaughtering performance and the weight of different carcass cuts. For almost all criteria chosen the crossbred individuals recorded better results.

THE RACES MANGALITZA RED VARIETY AND BAZNA BREED IN CLUJ COUNTY

Mangalitza race, it is a races of old formation, ab out it`s origin there are many opinions: some authors consider that it was formed from Sus-scrofa ferus, by others from a cross between roman pigs and local primitive ones, wich resulted from Sus-sc rofa ferus, and others consider it`s a domestic for m of the wilde Sus mediteraneus.

The heads is middle in size, the snout is cylindrical and light concave by profile. The back is convex, the croup is wry. The skin is thick, with the specific color for each var iety. The robe is formed by curly hair and abundant down. It has a reduce prolificity (5 – 6 suckling pigs a t one farrowing); the sows are not good mothers. Besides their low capacity of suckling, th ey crush the pigs. It si a middle precocious race reaching the maturity at 3.5 – 5 years (the sexual maturity is installed at 11 – 12 months). It is ver y resistant and is suitable for the maintenance on th e pasture, being very demanding for the stable conditions. Mangalitza race it is suitable for extensive breed ing, but because the fat consumption has diminished, the perspective of breeding are reduce to only maintaining some nuclei as genetic stock of pure race. Bazna race. It was formed by a cross of Mangalitza and Berk races, 100 years ago, around Bazna area. During the passing of the time it has s uffer infusions of Yourk race. It belongs to the meat – fat productive type, the exterior aspect and the productions are variable, with the breeding conditions. It is middl e large, and the weight can reach to 140 – 200 kg a nd even more, till 230 kg. The head is small till middle, with a concave profi le, and ears have variable size (small or large). The body is middle in length (in some indiv i uals small), cylindrical the back line is light convex (sometimes right). The hams are middle sized .

It’s color is black with white belt which surround the body in the shoulders and anterior legs area, with a width vary between 2 – 3 cm to 30 – 40 cm. The prolificity is 8 – 9 pigs per farrowing, t he sows are good mothers. The precocity is good at 11 – 2 months are good for reproduction; they reach maturity at 3 – 3.5 years. The Bazna pig is suitable for breeding in private f armstead and can satisfy the consum needs of population. It has even that more reduce perspec tive of breeding comparing with white races, which are more economically.
