Breeding and Performance Potential of Puławska Pigs – A Review

AbstractThe aim of the study was to discuss breeding of pigs of the Puławska breed, which is included in a Genetic Resources Conservation Programme, and to analyse performance parameters that are useful in domestic pig production. The Puławska breed is the oldest native breed of pig in Poland. Since 1996 it has been protected by a genetic resources conservation programme, owing to breeding traditions and the production traits characteristic of the breed. The use value of these pigs is currently at the level of maternal breeds: number of live piglets born per litter – 10.54; number of piglets reared per litter – 9.37; daily weight gains – 569 g for breeding boars and 562 g for breeding gilts; meat content – 54.6% for breeding boars and 54.9% for breeding gilts. An important element in favour of the use of this breed in domestic production of fresh pork and pork products is its meat quality parameters. The mean values for physical traits (WHC 22.42%, pH45 6.47, pH24 5.63) and chemical parameters (protein 22.70%, fat 2.65%) are characteristic of meat of normal quality. The Puławska breed can be used to produce high-quality fresh meat and meat products, including traditional and regional ones. Puławska pigs are bred and reared according to the principles of sustainable agriculture, which reduces the negative impact of pig production on the natural environment.

Abstract The material for the study consisted of 80 samples taken from the longissimus lumborum (LL) and semitendinosus (ST) muscles of young bulls of five breeds (8 samples of each muscle per breed), including three native breeds included in the genetic resources conservation programme, i.e. Polish Red, White-Backed and Polish Black-and-White, which together with the Simmental and Polish Holstein-Friesian breeds. The content of the elements (K, Na, Mg, Ca, Zn, Fe, Mn, and Cu) analysed in the meat of the young bulls (fattened in a semi-intensive system on fodder from permanent grassland) was found to depend (in varying degrees) on the breed of cattle. The greatest differences (P<0.01 and P<0.05) were noted between the Polish Holstein-Friesians (PHF) and the remaining breeds, mainly in the content of Mg, Ca, Zn and Mn. The results obtained in the four other breeds for most of the macro- and microelements were more uniform, with the highest content noted in the muscles of the young bulls of the native breeds.

Nutritional Value and Technological Suitability of Milk from Cows of Three Polish Breeds Included in the Genetic Resources Conservation ProgrammeThe study included milk obtained from cows of three native cattle breeds, i.e. White-backed (BG), Polish Red (RP) and Polish Black-and-White (ZB) kept under conventional conditions. The reference group consisted of milk from Polish Holstein-Friesian cows (PHF) maintained in the intensive system and milk from Simmental cows (SM) kept under conventional conditions. The following parameters were determined in 976 samples of milk: content of fat, protein, casein, lactose and solids; acidity (pH value); heat stability; rennet coagulation time; content of α-lactalbumin, β-lactoglobulin, serum albumin, lactoferrin and lysozyme. Additionally, a certain proportion of samples was investigated for fatty acid profile and content of macro- and microelements. Cows of native breeds produced milk of higher nutritional value (higher content of whey proteins and polyunsaturated fatty acids, including CLA) and more suitable for processing as compared to PHF cows. Milk from cows of the Polish Red breed was the most valuable in terms of these parameters, which can be associated with a distinctive phylogenetic origin of this breed. The favourable parameters in regard to the nutritional value and technological suitability of milk obtained from analysed population of cows of 3 breeds included in the programme of genetic resources conservation are therefore an important reason of validity for subsequent implementation of this programme.

Abstract The aim of this study was to conduct genetic analysis of 219 cold-blooded Sztumski mares, which were enrolled in the genetic resources conservation programme in 2008. The inbreeding level in the mares, their average genetic relationship with the population, and the average coefficient of kinship were analysed, as well as the number and origin of common ancestors (founders of the population) were determined. The age structure and coat colour in the mares, as well as the size and geographical distribution of the herds were also determined. Over 97% of the mares enrolled in the conservation programme were inbred. The average inbreeding coefficient was 1.93% and ranged from 0% to 32.6%; the average relationship coefficient (2.38%) for the population was the highest in the group of mares aged 9 to 11 years (2.63%); the average kinship within the population was 2.89% and ranged from 5 to 5.99% in the case of five mares. The mares descended from 785 founders, including 561 mares (mainly cold-blooded Sztumski and Sokólski breeds) and 224 stallions (mainly Ardennes and Belgian breeds). Distribution of the herds does not fully reflect the historic region from which the breed originated, while the population itself is scattered and kept in many herds, most of which have 2 (occasionally up to 6) mares.
