The effects of caponization on growth performance, carcass characteristics, meat quality and fatty acid profile of breast and drumstick of Mos and Sasso genotypes, reared in free-range production system were examined. A total of 47 birds of Mos breed (19 Castrated and 25 Entire) and 37 of Sasso X-44 (18 Castrated and 19 Entire) slaughtered at 32 weeks were used in this trial. The growth of broilers and the differences between genotypes and caponization effects were modelled by Weibull-growth equation. Capon's growth was higher than that obtained by roosters and Sasso weight was greater than Mos results (P<0.05). For both genotypes the chemical composition of breast and drumstick cuts showed significantly higher values of intramuscular fat (P<0.0001) and lesser values of moisture (P<0.0001) in capons in comparison with intact ones. In Mos breed, capons exhibited significantly (P<0.0001) higher values of breast and drumstick luminosity and yellowness, as well as lower values of redness. Regarding Warner-Braztler test (WB), there were no significant differences (P>0.05) by caponization effect, but hardness measured using textural profile analysis was lesser in meat from capons. Finally castration of animals led to important modifications in the intramuscular fat because meat from capons showed significantly lower values for total saturated fatty acids (SFA) and higher polyunsaturated fatty acids (PUFA). Nutritional indices were also more favorable in capon's meat, so overall fatty acid profile of capons was desirable from the viewpoint of human nutrition. © 2016, Walter de Gruyter GmbH.

In this work we study the growth and feed intake of male Galiña de Mos breed to reach the socalled minimal commercial weight stipulated by many authors and the market at around 2.1 kg weight, in two different seasons of the year, winter and spring, compared with a blonde chicken strain commonly used in Galicia, Sasso T-44. A hundred and thirty male, sexed, chicken T-44 and 400 Mos chicken unsexed (until to 4 weeks of age, when males were separated for the study) were raised in the Centro de Recursos Zooxenéticos de Galicia under extensive conditions. It was observed a significantly higher feed intake, both in the native breed and the industrial hybrids, in chicken reared in winter compared to those of spring, due to the influence of different temperatures observed. There were no major differences in the age at which reached 2.1 kg weight, since Mos's reached the 87 and 89 days in spring and winter respectively and 68 and 70 days in the T-44.

The Ovella Galega is a endangered sheep breed and is protected by a Conservation and Recovery Programme, in order to keep the genetic variability. A growth and carcass study was made on Ovella Galega lambs, whose main objetive is its characterization. Ten male lambs from single birth and fed solely on their mother's milk, all of them registered in the Record of Births of Stud-Book, were slaughtered at 45 days old. The growth and average dayly gain are in accordance to results published in other breed studies. The results show a high commercial yield (59%), apart from appropriate percentages in 1st and 2nd market categories.

The aim of this research was to study the Mos rooster breed growth performance, carcass, and meat quality. The breed effect (Mos vs. Sasso T-44) and finishing feed in the last month (fodder vs. corn) on animal growth, carcass characteristics, meat quality, and fatty and amino acid profiles were studied using a randomized block design with initial weight as covariance. In total, 80 roosters (n = 30 of Sasso T-44 line and n = 50 of Mos breed) were used. They were separated by breed and allocated to 2 feeding treatment groups (concentrate and corn). Each feeding treatment group consisted of 15 and 25 roosters, for Sasso T-44 line and Mos breed, respectively. Finishing feeding did not affect growth parameters in the 2 genotypes of rooster tested (P > 0.05). Nonetheless, the comparison between both types of roosters led to significant differences in growth parameters (P < 0.05). Regarding carcass characteristics, no significant influences of finishing feeding treatment (P > 0.05) were found, and as expected, carcass weight clearly differed between genotypes due to the lower growth rate of Mos roosters. However, drumstick, thigh, and wing percentages were greater in the Mos breed than in the hybrid line. In color instrumental traits, roosters feeding with corn showed breast meat with significantly (P < 0.001) higher a* and b* values than those of cocks feeding with commercial fodder. Values of shear force were less than 2 kg for both genotypes, thus it can be classified as very tender meat. Finishing with corn significantly increased (P < 0.001) the polyunsaturated fatty acid content in the breast; the Mos breed had a polyunsaturated to saturated fatty acid ratio of 0.73. The amino acid profile of the indigenous breed was not similar to that of the commercial strain. Finishing feeding treatment had a greater influence than breed effect on amino acid profile. © 2012 Poultry Science Association Inc.

The aim of this research was to make a full study of the meat from Mos-breed roosters (Spanish indigenous chicken). To achieve this purpose, the type of breed (Mos vs. a hybrid line, Sasso T-44) and the effect of finishing treatment in the last month (corn vs. commercial fodder) on growth performance, carcass and meat quality (physicochemical and textural traits), fatty and amino acid profile, and sensorial description were studied. The finishing feeding effect did not modify the growth, but the differences between genotypes were statistically significant (P < 0.05), in where Sasso T-44 was the genotype that generated the best growths and associated parameters. With regard to carcass characteristics, no significant influences of finishing feeding treatment (P > 0.05) were found, and carcass weight clearly differed between genotypes due to the lower growth rate of Mos roosters. Drumstick, thigh, and wing percentages were greater in Mos breed than in Sasso T-44 birds, whereas breast (15.2%), that is the most highly valued piece of the chicken, was similar for both genotypes. Significant differences in pH, protein, and ash content between genotypes have been found, whereas finishing feeding treatment had an effect on myoglobin and redness index (P < 0.01), showing meat from roosters fed with corn had a higher luminosity. Despite the fact of the slaughtered age of birds, values of shear force were slightly higher than 2 kg (2.11 kg) for both genotypes, thus it can be classified as very tender meat. Mos breed showed a higher percentage of polyunsaturated fatty acids (25.90 vs. 22.74; P < 0.001) and a lower percentage of monounsaturated fatty acids (35.14 vs. 38.95; P < 0.001) than Sasso T-44 chicken muscles. Surprisingly, birds finishing with the corn diet (2 times higher in linolenic acid than fodder) did not increase their polyunsaturated fatty acid level in the breast, obtaining in the Mos breed a polyunsaturated to saturated fatty acid ratio of 0.69. The amino acid profile of the indigenous-breed breast was not similar to that of the commercial-strain breast; besides, finishing feeding treatment had more of an effect on amino acid profile, affecting the majority of amino acids, with the exception of phenylalanine and threonine. © 2012 Poultry Science Association Inc.

The goals of the current work were to analyse the population structure of 11 Spanish ovine breeds and to detect genomic regions that may have been targeted by selection. A total of 141 individuals were genotyped with the Infinium 50K Ovine SNP BeadChip (Illumina). We combined this dataset with Spanish ovine data previously reported by the International Sheep Genomics Consortium (N=229). Multidimensional scaling and Admixture analyses revealed that Canaria de Pelo and, to a lesser extent, Roja Mallorquina, Latxa and Churra are clearly differentiated populations, while the remaining seven breeds (Ojalada, Castellana, Gallega, Xisqueta, Ripollesa, Rasa Aragonesa and Segurea) share a similar genetic background. Performance of a genome scan with BayeScan and hapFLK allowed us identifying three genomic regions that are consistently detected with both methods i.e. Oar3 (150-154Mb), Oar6 (4-49Mb) and Oar13 (68-74Mb). Neighbor-joining trees based on polymorphisms mapping to these three selective sweeps did not show a clustering of breeds according to their predominant productive specialization (except the local tree based on Oar13 SNPs). Such cryptic signatures of selection have been also found in the bovine genome, posing a considerable challenge to understand the biological consequences of artificial selection.
