Evaluation of wheat or corn dried distillers' grains with solubles on performance and carcass characteristics of feedlot steers

[EN]A study was conducted on crossbred steers (n=275; 376±924 kg) to evaluate performance and carcass quality of cattle fed wheat or corn dried distillers’ grains with solubles (DDGS). The control ration contained 86.6% rolled barley grain, 5.7% supplement and 7.7% barley silage (DM basis). The four treatments included replacement of barley grain at 20 or 40% of the diet (DM basis) with wheat or corn DDGS. Steers were slaughtered at a common end weight of 645 kg with 100 steers randomly (n=20 per treatment) selected for determination of the retail yield of sub-primal boneless boxed beef (SPBBB). Data were analyzed as a completely randomized design using pen as the experimental unit. Feeding increasing levels of wheat DDGS led to a quadratic increase in dry matter intake (DMI) (P<0.01), whereas increasing levels of corn DDGS led to a quadratic decrease in DMI (P=0.01). Average daily gain was not influenced (P=0.13) by feeding wheat or corn DDGS, but cattle fed corn DDGS exhibited a quadratic increase (P=0.01) in gain:feed. As a result, a quadratic increase (P<0.01) in calculated NEg of the diet was observed as corn DDGS levels increased. A linear decrease (P=0.04) in days on feed (169, 166 and 154 d) was noted when increasing levels of wheat DDGS (0, 20 and 40%) were fed. Dressing percentage increased in a linear fashion with wheat DDGS (P<0.01) inclusion level and in a quadratic fashion (P=0.01) as corn DDGS inclusion level increased although other carcass traits were not affected (P=0.10) by treatment. The results indicate that replacement of barley grain with corn or wheat DDGS up to 40% of the diet (DM) can lead to superior performance (improved gain:feed or reduced days on feed, respectively) with no detrimental effect on quality grade or carcass SPBBB yield.

[EN]Traditionally writing skills have been given priority in language teaching and so, oral skills have been put aside. However, during the last years many voices have asserted the importance of oral skills. Therefore, they claim that oral language teaching must be emphasized at school. Also, the necessity of strengthening oral language is shown in the new curriculum. Nevertheless, those intentions are reflected in very different ways in textbooks. In this work we have looked into the treatment that oral language is given in teaching materials because, in our opinion, textbooks are one of the most important tools for teachers. The facts show that the importance given to oral language and the exercises and tools needed to work that skill are very different from one publishing house to another. Besides, we have confirmed that all the textbooks don’t satisfy the requirements proposed in the Basque official curriculum (e.g. didactic sequences) or that the approach to the text or the way to work with it are not always what they should be. Therefore, it is obvious that we have still a long way in the field of oral language and specially in the way of teaching oral skills
