Planning forage needs in beef cattle enterprises is necessary for efficient utilization of genetic and environmental resources in pastoral systems and to generate economic benefits in an environmentally sound way. Production risk evaluation is essential in feed planning for cow-calf operations in pastoral systems. The proposed method to accomplish with production risk in these systems is based on the time biological system is maintained in an acceptable state under adverse climate conditions. This is coined "buffering time". The buffering time is calculated for both animals and pasture using an energetic approach. For cows, the buffering time is the minimum period the animal takes to reach the lowest acceptable body weight. for pasture, it is period for herbage mass to decrease to its mininum acceptable pasture buffering time indicated that increasing stocking rates put grazing systems at a higher risk. |

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. |
