Comportamento de consumidores de carne de cordeiro na região norte do Paraná

For many years the marketing of sheep meat was disorganized, with slaughter of low quality animals. This has created an image unfavorable to the product. As this scenario changes, sheep meat is more prominent, especially lamb meat that serves market niches in large urban centers. The objective of this work was to measure the consumption and acceptability of sheep meat in the region of Londrina PR, according to the gender, age, level of schooling and family income of the persons interviewed, as well as to evaluate the sensorial parameters of sheep meat according to consumers without the information of the animal species, aiming to indicate guiding actions for the productive chain of sheep. A total of 951 inhabitants were interviewed and a consumer study was conducted with 134 inhabitants, both from Londrina and region, during the Agricultural and Industrial Exhibition of Londrina, in the year 2014. The main reasons for not consuming the meat is the lack of custom 44.1% followed by the fact of not liking 39.8%. Constantino et al. 2 PUBVET v.12, n.1, a19, p.1-7, Jan., 2018 The reason they do not like meat is the strong smell of the animal 44.8% followed by the sweet taste 20.2%. Regarding the acceptability of the sample, 47.01% of the consumers marked the meat as much as they liked, followed by 26.87% that tasted extremely, only 2.25% of consumers marked the meat as unpleasant. It is observed that the great barrier to increase the consumption of the sheep meat is the lack of custom and bad experiences that lead to the non consumption.

Desempenho, consumo de nutrientes e comportamento ingestivo de cordeiros alimentados com diferentes teores de torta de soja em substituição ao farelo de soja

The objective of this study was to evaluate the effect of replacing soybean meal by soybean cake in diets for feedlot Santa Ines lambs, evaluating performance, nutrient intake, ingestive behavior and biometric measures. Thirty intact males were used, weighing 23.63 ± 2.44kg, distributed randomly in five treatments, with 6 animals each, with the treatments being the levels of substitution of soybean meal for soybean cake, by 0; 25; 50; 75 and 100%. The ingestive behavior was assessed by visual observations every 10 minutes, during 24 hours. No significant effects were found on the parameters of performance, DM intake, and ingestive behavior. The average daily weight gain was 312,73g, and the average dry matter intake was 1,44kg/day. The inclusion of soybean cake led to a significant linear increase in ether extract intake in grams/day, in percentage of body weight and in percentage of metabolic weight. Cubic effects were observed in the parameters of acid detergent fiber intake. The rumination, feed intake and idleness time observed were 425,85; 194,50 e 789,29 min/day, respectively. Regarding biometric measurements, there was no significant effect of replacing soybean meal with soybean cake. The soybean cake can be used in replacement of soybean meal, but is important to pay attention on the content of residual lipids present in this byproduct of the biodiesel industry.
