Abstract: The objective of the present study was to evaluate the behavior of dairy cows confined in free-stall systems. Eighteen Holstein cows were evaluated in this research. The following frequencies were evaluated at 10-min intervals: stall occupancy, corridor occupancy, feeding, moving and being milked. The free-stalls were covered with rubber mattresses. Thermal variables such as dry bulb temperature, humid bulb temperature, black globe temperature and air velocity were recorded hourly. The data collections were made for 13 days in May, during autumn. Dynamics of social hierarchy was observed for 18 animals. The animals preferred to occupy the stalls located in quadrant 1, between the north and east axis, where there was less movement of people, tractors and vehicles. The cows occupied the free-stalls during the early morning and feeding occupancy was higher during the morning. Higher temperatures in the afternoon caused the longer occupation of the corridors by the cows during this period. Some dairy cows housed in a free-stall barn expressed dominant and/or hierarchical behaviors. |

Some genes affect meat quality in chickens. We looked for polymorphisms in the Gallus gallus α-RyR gene (homologous to RyR 1) that could be associated with PSE (pale, soft and exudative) meat. Because RyR genes are over 100,000 bp long and code for proteins with about 5000 amino acids, primers were designed to amplify a fragment of hotspot region 2, a region with a high density of mutations in other species. Total blood DNA was extracted from 50 birds, 25 that had PSE meat and 25 normal chickens. The DNA samples were amplified by PCR, cloned, sequenced, and used to identify single nucleotide polymorphisms (SNPs). The amplified fragment of α-RyR was 604 nucleotides in length; 181 nucleotides were similar to two exons from a hypothetical turkey cDNA sequence for α-RyR. A non-synonymous nucleotide substitution (G/A) was identified in at least one of the three sequenced clones obtained from nine animals, six PSE (HAL+) birds and three normal (HAL-) birds; they were heterozygous for this mutation. |
