in this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. the results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .the tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

Two experiments were conducted to measure the energy and nutrient digestibilities in NutriDense corn and other cereal grains. An additional objective was to evaluate the effect of balancing diets with AA on the values measured for DE and ME of corn varieties. In Exp. 1, 6 growing pigs were fitted with a T-cannula in the distal ileum and allotted to a 6 x 6 Latin square design to measure apparen...

weight resulted in a slight reduction in the true metabolizable energy content of corn.! Since corn's primary contribution to swine diets is energy, we generally think that low-test-weight corn is of lower feeding value than normal-test-weight corn. However, the 1992 corn crop did not exhibit nutrient content typical of lowtest-weight corn. Field observations failed to demonstrate a consistent ...

Three trials evaluated the protein and energy value of high-lysine corn for finishing calves. In Trial 1, 60 finishing steer calves were used to evaluate corn source (high-lysine vs control) and protein source (urea, blood meal [BM], corn gluten meal [CGM]) and level (BM and CGM addition; low, medium, high). Calves were individually fed using Calan gates for 102 d, and then were pen-fed (two pe...

Two experiments were conducted to determine DE and ME and the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of CP and AA in corn and corn coproducts (high-fat corn germ [HFCG], corn bran, liquid corn extractives [LCE], and a mixture of corn germ meal and LCE [CGM-LCE]) fed to growing pigs. In Exp. 1, 40 growing barrows (initial BW: 33.4 ± 5.77 kg) were housed...

Three experiments were conducted to measure energy, P, and AA digestibility in 2 novel co-products from the ethanol industry [i.e., high-protein distillers dried grains (HP DDG) and corn germ]. These products are produced by dehulling and degerming corn before it enters the fermentation process. Experiment 1 was an energy balance experiment conducted to measure DE and ME in HP DDG, corn germ, a...

Objective In previous studies, the relaxant, anticholinergic (functional antagonism), antihistaminic and its stimulatory effects on b-adrenoceptors of Nigella sativa have been demonstrated on guinea pig tracheal chains. In the present study, the relaxant effects of hydro-ethanolic, macerated aqueous (MA) and lipid-free macerated aqueous (LFMA) extract of Nigella sativa on tracheal chains of gu...

Many herbaceous lignocelluloses suitable for ethanol production have high extractives contents, such as some straws and corn stover. The high extractives content might affect pretreatment or enzymatic hydrolysis. In this study, extractives were removed from corn stover, and then extractives-free corn stover and ordinary corn stover were respectively pretreated using a liquid hot water (LHW) met...

A feeding trial evaluated the hypothesis that wet corn gluten feed would improve growth performance of cattle fed steam-flaked corn-based finishing diets and supply required degradable intake protein (DIP). The trial used 360 steer calves (initial BW = 288 +/- 11 kg) housed in 36 pens for 166 d in an incomplete 4 x 3 factorial arrangement of treatments. Pens of steers were assigned to treatment...

Two experiments were conducted to evaluate modified wet distillers grains (DGS) as a supplement for roughages. Wet DGS was superior to a mixture of corn and wet DGS as a supplement with tub-ground grass hay for growing steer calves in a 112-d study. Performance of steers fed the grass hay supplemented with DGS or the mixture of corn and DGS was superior to calves fed corn silage. However when D...
