Knowledge of the feeding value of the various ingredients in swine diets is important for accurate feed formulation and to estimate the value of these ingredients. Typically, it is not very accurate to use average values to estimate feed values of individual ingredient samples. The 1992 Saskatchewan crop is an example of how nutrient value can vary and was expected to vary considerably because of weather conditions. This crop presented a unique opportunity to estimate feeding value in different samples of various cereal grains, and more importantly, to identify relationships between feeding value and simple repeatable measurements on representative sub-samples. A study was conducted to determine feeding value of 16 different wheat samples for growing pigs.
\nSixteen wheat samples expected to vary in feed value were collected in Saskatchewan. Each sample was submitted for chemical analysis to determine dry matter, energy, protein, amino acid, starch, crude fibre, acid detergent fibre, neutral detergent fibre and ash content. The samples were also evaluated in a digestibility study to determine digestible energy content and digestibility of various nutrients. Of the 16 samples, 14 samples had been exposed to drought during the growing season. Differences in nutrient content between extreme samples were close to 30% for protein, 30% for lysine and 10% for digestible energy content. The durum wheat sample evaluated seemed quite different than the other wheat samples, and was therefore excluded from most of the statistical analysis. The current studies support the anticipated variation in feeding value between the different wheat samples of the 1992 crop in Saskatchewan.<\/p>\n","protected":false},"excerpt":{"rendered":"
