the present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. in the in situ experiment dacron bags were filled with 3 g alfalfa hay. this was incubated in the rumen of three ruminally cannulated ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...

in this experiment, fermentation parameters of a tmr ration determined with different levels of phosalone as an organophosphate pesticide (0, 100, 250, 500, 750 and 1000 ppm) and bentonite (0, 1 and 2 %dm of tmr) using in vitro batch culture and gas production techniques. the results from gas production showed that cumulative gas production for 96h after incubation significantly decreased with ...

Background: Sulphur is rapidly being recognized as fourth key nutrient for plants after nitrogen, phosphorus and potassium. It functions in several critical metabolic physiological processes, such Chlorophyll synthesis, Protein Activation of enzymes, Stress tolerance Seed production. This study was carried to investigate the effect synthesized nano sulphur combination with organic amendment ava...

The aim of the present study was the decolourisation of mixture of two dyes belonging to different groups by two Pseudomonas fluorescens strains (Sz6 and SDz3). Influence of different incubation conditions on decolourisation effectiveness was evaluated. Dyes used in the experiment were diazo Evans blue (EB) and triphenylmethane brilliant green (BG). Another goal of the experiment was the estima...

The hypothesis was proposed that the improved embryonic livability observed when higher incubation temperatures were imposed on eggs stored for 15 d prior to setting might have basis in energy metabolism. To test the hypothesis, fertilized turkey eggs were incubated either for the first 2 wk of development (experiment 1) or only the first week of development (experiment 2) at 37.8 degrees C com...

The objectives of this study were to explore whether heparin-binding proteins, separated by fast protein liquid chromatography from boar seminal plasma influence the release of prostaglandins F2α, (PGF2α), E2 (PGE2) and interleukin-6 (IL-6) by porcine endometrial and cervical cells and even bovine endometrial cells. In Experiment I, we showed that release of PGF2α by endometrial epithelial, end...

In oceanic communities, picophytoplankton often dominates phytoplankton biomass and productivity. Diel variations in abundance growth have been well documented. the current study, we used flow cytometry to assess short-term (3 h) of most dominant picophytoplankton, Synechococcus spp. picoeukaryotes, coastal regions northeastern Taiwan. To explore change mortality rate daytime over 24 h incubati...

during subsequent incubation in two experiments. Treatment groups had four replicate incubation trays of 150 eggs each. As expected, hatchability of fertile eggs declined with length of egg storage in both experiments (P<0.01). This was due to increases in both percentage early and late dead embryos in both experiments. Hatchability of fertile eggs was increased by SEU storage and turning durin...

Mangrove ecosystems are important for carbon storage due to their high productivity and low decomposition rates. Waterways have experienced increased nutrient loads as a result of anthropogenic activities it is unclear how this may affect cycles in downstream mangroves that receive these nutrient-rich waters. Using laboratory-based incubation experiment, study aimed assess the effects addition ...
