Six mature wethers (BW 72 kg) with ruminal, duodenal, and ileal cannulas were fed a basal (no added soybean meal [SBM]) diet or diets containing unheated SBM or SBM roasted at 165 degrees C for 75, 150, 180 or 210 min in a 6 x 6 Latin square experiment. Concentrations of indicators of heat exposure (NDF, ADF, and ADIN) in SBM increased with increasing roasting time. Organic matter digestion cha...

Efforts are being made to express toxin genes from the bacterium, Bacillus thuringiensis (Bt) in chickpea for minimizing the losses due to the pod borer, Helicoverpa armigera. However, there is an apprehension that acidic exudates in chickpea leaves may influence the protoxin-toxin conversion in the insect midgut, and thus, reduce the efficacy of Bt toxins. Therefore, we studied the influence o...

The effects of diets (i.e., high fibre, HF and high concentrate, HC) supplemented with either fumaric acid (FUM; 8 mmol/L) or maleic acid (MAL; 8 mmol/L) and different plant oils (35.0 g/kg dry matter; sunflower, SO; rapeseed, RO; and linseed, LO) on rumen sheep fatty acids (FA) concentration and biohydrogenation (BH) in batch cultures were examined. The oils rich in linoleic acid (SO, 535 g/kg...

There is considerable interest in the pathways by which carbon and growth-limiting elemental and biochemical nutrients are supplied to upper trophic levels. Fatty acids and sterols are among the most important molecules transferred across the plant-animal interface of food webs. In lake ecosystems, in addition to phytoplankton, bacteria and terrestrial organic matter are potential trophic resou...

The effects of two sugar alcohols on feed utilization, digesta retention, gut fermentation and serum lipid profiles were compared in normal and cecectomized rats to examine the possibility of the cecectomized rat as an experimental animal with relevance to humans. Semi-purified diets containing no sugar alcohol, 7% sorbitol or 7% lactitol were fed to normal and cecectomized rats for 16 days. Th...

The objective of a 2 × 2 factorial study with laying hens was to evaluate the effect of dietary energy and DL-methionine (Met) supplementation in a high protein but sulphur amino acid deficient organic diet for laying hens on egg production, egg quality, and N retention and N excretion in manure. The model trial was conducted with 72 Bovans Brown hens from 24 to 53 weeks of age, allocated to 4 ...

A 84 day experiment was conducted to evaluate the effect of sodium diformate NDF ® as commercial feed additives on growth performance and feed utilization of hybrid tilapia (♀ O. niloticus X ♂ O. aureus) fingerlings. Four treatments were applied; three levels of NDF ® (1 g kg -1 , 3 g kg -1 and 5 g kg -1 ) in addition to the control. The experimental diets containing (320 g kg -1 crude protein ...

The aim of this thesis was to increase our understanding about chicory (forage and root) as fibre source for pigs, by studying the effects of diets with inclusion of chicory on digestibility, digestion site, performance, gut microbiota and environment. In total 62 pigs were used, including newly weaned and growing intact pigs and growing post valve t-caecum (PVTC)-cannulated pigs. The weaned pi...

To study the effects of dairy production system on milk macromineral and trace element concentrations, samples were collected monthly in 2019 from 43 conventional 27 organic farms. Organic contained more Ca (1049.5 vs. 995.8 mg/kg), K (1383.6 1362.4 P (806.5 792.5 mg/kg) Mo (73.3 60.6 ?g/kg) but less Cu (52.4 ?g/kg), Fe (0.66 vs 2.03 Mn (28.8 45.0 Zn (4.51 5.00 Al (0.32 1.14 than milk.
