Applied Nutrition Problem No 1 Spring 2018Feeding Triticale to Dairy Cows- Brianna ParmentierSoil quality needs to be rejuvenated and protected. Planting corn to feed animals is no longer the only choice; it has been found that feeding triticale silage is both safe and a nutritionally comparable feed to use in dairy cattle production.Triticale is described as a hybrid crop of rye and wheat (Stalcup, 2009). When feeding this crop it is important to note that the maturity at harvest effects the nutrient quality such as protein levels in feed but with more maturity comes issues with corporeality of the feed (Castells et al., 2012). A feed analysis performed on triticale harvested during the soft dough stage contained levels of protein around 11.6% in the silage (McCartney and Vaage, 1993).When Triticale is in a high maturity state when fed as a silage it has resulted in decreased dry matter intake and a lower average daily gain during a trial done with heifers (McCartney and Vaage, 1993). When higher maturity feed particle size is chopped to be 8mm in length such as it was in a calf feeding study, the overall amount of triticale silage feed that was consumed was the greatest out of all feedstuffs offered due to its increased palatability (Castells et al., 2012). Lactating animals fed triticale silage had decreased milk yields which was a correlation with the old maturity of the feedstuff. (Harper et al., 2017). Milk yields in a study done presented overall lower yield in feeding triticale silage then feeding corn silage (Cosentino et al., 2015).Feeding triticale to lactating dairy cows is a safe practice but this product is high in fiber and therefore shouldn’t be fed in high quantity’s like in the study where they used only 10% in diet (Harper et al.,2017). Based on the readings, feeding lower maturity silage will make the feed higher in protein, palatability and increase dry matter consumption. Depending on other ingredients in the diet and the maturity of the silage chosen will impact amount fed in the ration.
