Abstract

Ancient wheat species attracts more attention recently due to their health benefits and suitability for organic farming. With this attention, the possibilities of using ancient wheat species and especially their by-products in animal nutrition are emerging. Unlike modern wheat varieties, emmer is known as one of the ancient wheat varieties, has hull covering its grains. Approximately 70% of the total plant weight consists of hulls and stalks. Looking at the literature, limited studies has been conducted regarding the evaluation of the hull and stalk parts of emmer wheat as feed. Herein, this study aims to determine the nutritional values of emmer wheat and its by-products. The feed value of the plant was analyzed in five parts (hulled grain, stalk of plant, hull, naked grain and flour). For each part, dry matter (DM), crude protein (CP), ether exract (EE), crude ash (CA), starch, crude fiber (CF), acid detergent fiber (ADF), neutral detergent fiber (NDF), acid detergent insoluble crude protein (ADICP), neutral detergent insoluble crude protein (NDICP), lignin and mineral analyzes were made. In addition, non-fiber carbohydrate (NFC), digestible dry matter (DDM), dry matter intake by animal body weight (DMIBW), total digestible nutriton (TDN1X), net energy lactation (NEL3X), metabolic energy (ME), net energy maintanence (NEM), net energy gain (NEG), energy and digestibility calculations were performed. The protein content of emmer grain was observed higher than that of modern wheat. ADF and NDF values of the emmer wheat stalks are lower than modern wheat stalks and therefore have better digestibility values. Additionally, the higher resistance to starch digestion compared to modern wheat varieties may be a reason for preference in ruminant feeding.
