1. The fate of glucosyl urea (GU), lactosyl urea (LU) and corresponding mixtures of the free sugars and urea and their degradation products were examined during in vitro incubation of the compounds with rumen contents taken from donor sheep and steers at various stages of adaptation to these compounds.2. The sugar–urea bond was virtually unattacked in rumen contents from unadapted sheep and steers but generally a slow release of the galactose moiety occurred. After feeding LU or GU to animals for a period of approximately 10 d, the rates of disappearance of both bound urea and sugar had increased, but were still markedly slower than those of the corresponding free sugars and urea. In vitro rates of degradation of both free lactose and urea also increased in response to the feeding of lactose and urea to rumen contentdonor animals.3. Ammonia accumulation in rument contents when GU or LU were the substrates was notably lower than when equivalent amounts of glucose and urea or lactose and urea were the substrates.4. Bacterial growth was estimated using an vitro method based on incorporation of32P into bacterial nucleic acids. Markedly different patterns of bacterial growth were observed depending on whether LU or lactose and urea were the substrates.

Abstract Per unit energy, fiber is among the most expensive components of the ruminant diet. Wastes from human enterprises may represent the next step in feedstuff investigation. In an effort to minimize the anthropogenic waste contribution, and as a means to find a more cost-efficient resource to feed ruminant animals, our objective was to determine the nutritive value of disposable coffee cups and warmer sleeves in relation to ruminant nutrition. Discarded cups and warmer sleeves were collected from employees at Tarleton State University in fall of 2017. Cups were obtained from five sources, and warmer sleeves were obtained from two sources. Cups and sleeves were dried at 55°C for 72 h and ground to pass through a 2-mm screen. Ground samples were subjected to a batch-culture in vitro true digestibility (IVTD) assay. Original samples and incubated residues were then assayed for DM, NDF, ADF, and CP. Data were analyzed as a random effects model completely randomized design using the MIXED procedure of SAS. There was no effect (P > 0.05) of source (n = 5) or type (cup or sleeve) for contribution to variance of NDF, ADF, IVTD, and in vitro NDF digestibility (IVNDFD). Mean values for NDF, ADF, IVTD, and IVNDFD across samples were 89.5, 81.4, 24.5, and 18.7%, respectively. Results indicate a low digestibility coefficient for these waste products, thus meaning its use as a feedstuff could be questionable. However, such results provide insight into niches where this product and other anthropogenic wastes may fit in the larger picture of ruminant nutrition

There are small number of tables that show digestibility and energy contents of compound feeds produced by feed factory in different regions of Turkey. Thus, in this paper, four different compound feed types (dairy cattle, beef cattle, calf and lamb growing feeds), totalling 78 compound feeds were analysed to determine their feeding value, dry matter (DM), organic matter (OM) digestibility and energy content (digestible energy (DE), metabolisable energy (ME) and net energy for lactation (NEL). As a result of this study, the crude fiber (CF) levels were higher than standard values in calf and lamb compound feeds and beef cattle compound feeds; however, in the dairy cattle and calf and lamb compound feeds, the crude protein (CP) values were lower than standard values. These findings are considered highly important for the region’s animal feeding. According to our results, the compound feeds for dairy cattle and lamb being used for ruminant nutrition in Diyarbakir Province of Turkey were found to have low nutrient qualities; however, in the calf feed both the metabolisable energy level and nutrient quantities were low.

Forage Legumes

Fresh, dried or preserved, forage legumes are highly suitable for use as roughage in the animal diet because of their richness in protein, vitamins, and mineral matter. Previous work on forage legumes breeding for improved quality has mostly focused on increasing the crude protein content of these crops. Another major parameter of forage legume quality, especially from the point of view of ruminant nutrition, is the in vitro digestibility of dry matter. Values of both these parameters decrease with age in all forage legumes due to a reduced leat to stem ratio and lignification. The decrease in digestibility after budding comes as a result of an increased lignin content and a rise in the proportion of starch polysaccharides. In the context of forage quality, especially important from the point of view of ruminant nutrition is the relation between structural and nonstructural carbohydrates. Structural carbohydrates include neutral detergent fiber (NDF) and acid detergent fiber (ADF), while non-structural ones are mostly starch. The latest efforts in forage legume breeding should encompass certain specific traits in order to completely fulfill the needs for safe feed in animal husbandry.
