This study examined the reticulo-rumen characteristics of the microbial community and its fermentative characteristics in milk-fed, at weaning and finished lambs in a conventional fattening system. Five lambs were assigned to each of three groups: milk-fed lambs slaughtered at 30 days (T30), weaned lambs slaughtered at 45 days (T45) and 'finished lambs' slaughtered at 90 days (T90). At slaughte...

Particle size alterations during neutral detergent fiber (NDF) determination and in situ rumen incubation were analyzed by dry sieving and image analysis to evaluate the in situ procedure for estimation of NDF degradation parameters and indigestible NDF concentration in terms of particle size. Early-cut and late-cut grass silages, corn silage, alfalfa silage, rapeseed meal, and dried distillers...

the objective of this study was to investigate the effects of summer savory essential oil (sseo) with cereals (based on barley or corn) on performance, rumen volatile fatty acid concentrations and some blood parameters of west azerbaijan native kids. in a randomized complete block design with a 3×2 factorial (0, 200 and 400 mg/d of sseo × barley or corn grain based diets) arrangement with 6 rep...

the aim of this study was to assess the effect of several doses of spearmint essential oil (seo; 0, 250, 500, 750 or 1,000 µg ml-1 buffered rumen fluid) on the fermentation kinetic and digestibility using in vitro gas production technique. a total mixed ration (30% roughage: 70% concentrate) was incubated with buffered rumen fluid. in vitro gas production, asymptotic gas production (a), rate of...

A mechanistic model describing rumen digestion is presented. The model consists of 22 compartments for classical nutrients, microbes associated with either solids or fluid, and 8 amino-acid compartments. An empirical approach for volatile fatty acids production is used. Sensitivity and behavioural analysis on several parameters demonstrated the need to improve knowledge concerning certain facto...

Large (>1600 microm), ingestively masticated particles of bermuda grass (Cynodon dactylon L. Pers.) leaf and stem labelled with 169Yb and 144Ce respectively were inserted into the rumen digesta raft of heifers grazing bermuda grass. The concentration of markers in digesta sampled from the raft and ventral rumen were monitored at regular intervals over approximately 144 h. The data from the two ...

ABSTRACT Rumen acidosis is a fatal disease that reduces milk and pregnancy yield due to digestion of cattle when not detected. Diagnosis this can be achieved by monitoring the nutritional parameters cattle. Internet Things (IoT) technology used in these kinds processes such as tracking within scope Industry 4.0. Thanks IoT, data collection, analysis, processing stages are carried out instantly ...

It has been known for decades that microbial fermentation within the rumen is critical to postnatal rumen epithelial growth and maturation in ruminants, but the underlying mechanism is largely unknown. In this study, we determined the effect of rumen fluid, which should contain all products from rumen fermentation, on growth of rumen epithelial cells in vitro. Addition of 10% rumen fluid from c...
