| dc.description.abstract | Malhado de AlcobaƧa (MA) is a swine breed from center west Portugal, recognized in 2003. Herdbook (LGMA) has information of >17,000 animals (1985-2022). ItĀ“s a very endangered breed with only 244 sows, 18 boars and 12 breeders. Within the scope of MAās genetic conservation plan, for genetic evaluation, genetic parameters and fixed effects were estimated for birth weight (PN), for adjusted weight at 30 d (P30) and at 90 d (P90). Pedigree records (n=16,883) and weighing records (nPN=9,198; nP30=5,799; nP90=2,429) from LGMA of 362 litters were compiled. Genetic parameters and fixed effects, genetic values and precisions were predicted for PN, P30 and P90, through BLUP, with a mixed model including fixed effects of breeder Ć year of birth, season of birth, sex, age of mother (linear / quadratic effect) and as random effects genetic value of animal, maternal genetic effect and permanent environmental effect of litter. Fixed effects of prolificacy and number of weaned piglets were included as covariates, respectively, in PN and P30/P90 analyses. Mean values for PN 1.32Ā±0.28 kg, 7.16Ā±1.6 kg P30 and 34.1Ā±6.4 kg P90 were recorded. For PN, P30 and P90, respectively, a heritability for direct effects of 0.170Ā±0.156, 0.145Ā±0.161 and 0.293Ā±0.175; a maternal heritability of 0.084Ā±0.109, 0.124Ā±0.173 and 0.250Ā±0.186 and a genetic correlation between direct and maternal effects of -0.344, -0.524 and -0.174 was estimated. Permanent environmental effect of litter was 0.395Ā±0.056 PN, 0.403Ā±0.086 P30 and 0.129Ā±0.047 P90. In fixed effects, a superiority was observed for males of +0.031 kg PN, +0.046 kg P30 and +0.201 P90. Breeder Ć year effect showed maximum differences of 0.93, 5.21 and 19.25 kg for PN, P30 and P90, respectively, with Spring being the best season of birth. Sow age at farrowing had a quadratic effect for all traits. For each increase of 1 piglet in prolificacy, PN, P30 and P90 were reduced by 4, 7 and 58 g, respectively. | pt_PT |
