Dry matter (DM) degradation of wheat straw (WS), barley straw (BS), lucerne hay (LH) and maize silage (MS) was determined using two different techniques: (i) in vitro gas production and (ii) nylon bag degradability technique. In vitro gas production and in situ DM disappearance were measured after 3, 6, 12, 24, 48, 72 and 96 hours of incubation. In situ and in vitro DM degradation kinetics was ...
this research was conducted to determine the effect of gamma ray (gr) (100 and 150 kgy), sodium hydroxide (50 g/kg dm) and calcium oxide (160 g/kg dm) on gas production parameters and in vitro digestibility of soybean straw. all treatments, except for the gamma ray (100 and 150 kgy) did not have gas production up to 4 hours after incubation and there was a lag time. from 8 to 96 hours of incuba...
the effect of inclusion of garlic essential oil (eo) at 33, 66 and 100 μg ml-1, raw garlic (gar) at 5, 10 and 15 mg ml-1 and monensin (mon) at 7.5 μg ml-1 of incubation medium on organic matter digestibility (omd) was studied with in vitro gas production, ankom daisyii and conventional in vitro (ivomd) methods. the material was incubated with sheep ruminal fluid and the experimental design was ...
this study was conducted to evaluate the effects of different heating treatments (autoclaving, roasting, steam flaking and microwave irradiation) on chemical composition, anti- nutritional compounds (tannin and phenolic), in situ dry mater (dm) and crude prate in (cp) degradability. three fistulated bull in a complete randomized block design and in vitro gas production kinetics (complete random...
the effect of three levels of eucalyptus leaf (0, 28.65 or 57.37mg/200mg substrate), which were either oven, freeze or air dried on in vitro ruminal fermentation characteristics was assessed. the studied parameters were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability, partitioning factor (pf) (ratio of substrate truly degr...
background to current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (ivep). objectives the aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on ivep yield. materials and methods ovaries from slaughtered ewes in breeding sea...
This study investigated the effect of chilling and freezing (for 24 h) canine feces on in vitro gas production kinetics and fermentation end product profiles from carbohydrate-rich (in vitro run 1) and protein-rich (in vitro run 2) substrates. Feces were collected from 3 adult retriever-type dogs fed a canned diet for at least 2 wk. Each fecal sample was divided into 3 portions: 1 portion was u...
17-35 ABSTRACT Rumen fermentation kinetics of grass and silage, differing in age and yield (1500 -7900 kg DM ha), were studied in sacco and in vitro, using the gas production test and the Tilley and Terry technique. An increasing yield increased the content of NDF and lignin in grass and decreased protein content, in vitro degradability measured by the Tilley and Terry method, and rate of ferme...
this study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (p-pb) on in vitro gas production using fistulated sheep. one portion of p-pb was mixed with four portions of water for 48 h. the extracted product was sprayed on soybean meal (sbm) or canola meal (cm) with an equal ratio (1:1 v/w) and dried in the shade. the expe...
