In the present study, chemical composition and in situ rumen dry matter degradability (DMD) of some tree species (cherry, apricot and almond tree leaves) were determined. Crude protein (CP) concentration varied from 6.76% for almond tree to 2.76% for cherry tree, neutral detergent fiber (NDF) and acid detergent fiber (ADF), from 29.2, 20.8% for apricot tree to 20.8 and 15.8% for almond tree lea...

The present study was carried out to evaluate the effect of prill fat and rumen protected choline supplementation on daily dry matter intake, body weight changes and economics in lactating Murrah buffaloes (n=18) divided into three equal groups (Control, T1 and T2). Buffaloes in all the three groups were fed similar basal diet as total mixed ration comprising of berseem green fodder, wheat stra...

The effect of two levels of fishmeal substitution (50 (FM1) and 150 (FM2) g/kg) of a grass silage control diet (C) on the rumen digestion of organic matter and nitrogen, and the small intestinal disappearance of amino acids was examined in young growing cattle each equipped with simple PVC cannulas in the dorsal sac of the reticulo-rumen, the proximal duodenum and the terminal ileum. The silage...

Without any doubt, the polyester-bag method is a very useful and common tool when evaluating ruminal utilization of feed. The first-order kinetic model as described by 0rskov & McDonald (1979), McDonald (1981) and Dhanoa (1988) is widespread and commonly used for description of disappearance curves. The model has two drawbacks clearly identified: (a) the assumption of fraction A being totally a...

The nutritive values of non-processed and processed pistachio peel with Neurospora sitophila were evaluated. The chemical composition of samples was evaluated by laboratory analysis. An in vitro digestibility study was done to determine digestibility coefficients of dry matter (DM), organic matter (OM). Digestible organic matter in the dry matter (DOMD) to estimate the metabolizable energy (ME)...

The present study aimed to evaluate the use of biochar as a feed additive on nutrient utilization and livestock performance by employing meta-analysis method. Various in vitro vivo studies regarding effects rumen fermentation, disappearance, total gas, methane production, microbial population, intake, growth performance, blood constituents, digestibility nitrogen retention were tabulate...

The aim of this experiment was to determine the effects of conjugated linoleic acid (CLA) on milk production and composition, and milk fatty acid profile of dairy Holstein cows. Three lactating Holstein cows (203 ± 9 DIM; mean ± SD) fitted with rumen fistula were used in a 3 × 3 Latin square experiment with 21-d periods, including a 14-d adaptation period followed by a 7-d sampling period. Trea...

Because of the complexity of the interactions involved very few attempts have been made to trace the fate of ingested food in the course of its digestion and absorption along the alimentary tract of the ruminant. Elsden, Hitchcock, Marshall & Phillipson (1946) made a comparative study of the weights of the digesta and their dry-matter and volatile fatty-acid content in the consecutive parts of ...

The study aimed at assessing the prevalence of poor rumen development, presence of rumen plaques, rumen papillae hyperkeratinization, and abomasal lesions in veal calves and to investigate risk factors for their occurrence at the farm level. Within a wide cross-sectional study, a sample of 170 veal farms representative of the European veal meat production systems was considered in the 3 major p...

Hominy feed (HF) has been evaluated in feedlot and dairy rations but not as a supplemental energy source for lactating beef cows. The objective of this study was to determine the effect level HF supplementation on intake, digestibility, ruminal fermentation characteristics, situ dry matter (DM) disappearance bermudagrass hay. Five ruminally cannulated cows (body weight (BW) = 596 kg, SE 13.9) w...
