RESUMO
A trial was conducted to investigate the effects of dietary Coriandrum sativum seeds on carcass performance, immune system, blood metabolites, rumen parameters and meat quality of Lambs. 16 Sanjabi lambs of 27 ± 5.1 kg during post-weaning (97 d of age) period were randomly selected. Four diets including 0, 1, 3, and 5% coriander seeds, replaced by Alfa alfa in the diet, were considered. A 30:70 alfalfa hay: concentrate diet for a period of time (97 to 187 d of age) was used. The results showed that feed intake was significantly increased by adding coriander seeds, linearly. There was no significant difference for apparent digestibility of crude protein, crude fat, neutral and acidic detergent fiber, crude ash, rumen fluid pH and ammonia nitrogen at 0, 2 and 4 h after feeding, Meat dry matter, ash, crude protein and fat, and the meats fatty acid profile (p > 0.05). Dietary coriander seeds had a significant effect on neutrophils, lymphocytes, monocytes and eosinophils (in days 7 and 14 of trial) and blood metabolites at the middle of trial. Obtained results suggested that supplementation of coriander seed may have limited effects on nutrient digestibility, ruminal parameters, meat quality, blood cells and metabolites.

Os testes de vigor são essenciais em programas de controle de qualidade de sementes e, o de envelhecimento acelerado é considerado como um dos mais difundidos para a avaliação do vigor das sementes de várias espécies cultivadas, sendo capaz de proporcionar informações com alto grau de precisão. Nesse sentido, a pesquisa teve como objetivo estudar a metodologia do teste de envelhecimento acelerado, visando à identificação de diferentes níveis de vigor de lotes de sementes de coentro (Coriandrum sativum L.). Para isso, quatro cultivares (Português, Super Verdão, Taboca e Verdão), representadas por três lotes de sementes cada, foram submetidas às seguintes avaliações: germinação, primeira contagem do teste de germinação, emergência de plântulas, índice de velocidade de emergência, altura de plântulas, massa da matéria seca da parte aérea da plântula, envelhecimento acelerado pelos procedimentos tradicional e em solução saturada de NaCl (38 e 41ºC durante 48, 72 e 96 horas) e grau de umidade no início dos testes e, após a incubação para o teste de envelhecimento acelerado. O delineamento estatístico utilizado foi o inteiramente casualizado, no esquema fatorial 3 x 2 x 3 (lote x temperatura x período de envelhecimento), com quatro repetições para cada cultivar e teste. O teste de envelhecimento acelerado no procedimento tradicional a 41ºC/48 horas e em solução saturada de NaCl por...(AU)
The vigor tests are essential in programs of quality control of seeds, and the accelerated aging test is one which can be used for this purpose. In this sense, this paper aimed to study the methodology of the accelerated aging test, in order to identify different levels of vigor seed lots of coriander (Coriandrum sativum L.). To do so, four cultivars (Português, Super Verdão, Taboca and Verdão), each represented by three lots of seeds, they were subjected to the following assessments: germination, first count of germination, seedling emergence, speed of emergency seedling height, dry mass of the aerial part of the of seedlings, accelerated aging by traditional procedures and saturated NaCl (38 and 41C for 48, 72 and 96 hours) and moisture content at the beginning of the tests and, after incubation to accelerated aging test. The statistical design was completely randomized in a factorial 3 x 2 x 3 (lot x temperature x aging period), with four replications for each cultivar and test. The accelerated aging test at 41C/48 hours (traditional procedure) and 41C/72 hours (saturated NaCl) was sensitive to evaluated of physiological potential of coriander seeds.(AU)
