Four breed types with 12 cows/breed-type (Hereford x Angus, AHx; Charolais and Angus and Charolais x Hereford, Cx; Jersey x Angus, Jersey x Hereford, Jx and Simmental x Angus, Simmental x Hereford, Sx) were used to estimate nutrient requirements for zero daily weight change. Four nonpregnant, nonlactating cows of each breed type were assigned to one of three feeding levels [90 kcal metabolizabl...

Five trials in five locations in the United States involving 512 steers were conducted to evaluate the effect of monensin [200 mg/d in .9 kg of supplement (Ru mensin )] and estradiol-controlled release implants ( Compudose ) administered alone and in combination on average daily gain (ADG) in steers on pasture. The effect of energy supplementation on rate of gain was also evaluated in these sam...

Wether sheep were fitted with rumen fistulas and polyethylene tubes to the abomasum and were given all nutrients by intragastric infusion. In Expt 1 volatile fatty acids (VFA) were given at 340, 450 and 630 kJ gross energy (GE)/kg metabolic weight (W0-75) and protein at 0, 150, 300, 600, 900 and 1500 mg nitrogen/kg W0-75. In Expt 2 VFA were infused at 450 kJ GE/kg W0-75 and protein at 0 and 300...

A study has been made of the effect of diphenylhydantoin (DPH) upon the levels of gamma aminobutyric acid (GABA) and succinic dehydrogenase in rat Purkinje cells. DPH was administered over 26 days in chronic experiments using controls receiving the same injection vehicle without DPH. Animals in this group received daily 1.25 mg/kg body weight, 12.5 mg/kg body weight, and 50 mg/kg body weight DP...

The effects of air dried ginger powder (0.1g/kg body weight, po, for 75 days) were studied on experimentally induced atherosclerosis in rabbits by cholesterol feeding (0.3g/kg body weight, po). Cholesterol feeding for 75 days lead to distinct development of atheroma in the aorta and coronary arteriesof the rabbits and this was significantly inhibited by about 50% following ginger administration...

This study was conducted to evaluate the effects of replacing maize in quail diets with graded levels of rumen filtrate-fermented cassava meal (FCM) on growth and egg production performances. Cassava meal (CM) was mixed with dried manure of layer at 75 g/kg CM, which was mixed with freshly collected rumen filtrate (at 1 L/5 kg CM), and finally fermented in sealed bags for 14 days. It was then s...

abstract salinity is one of the major abiotic challenges influencing plant productivity worldwide. to examine the response of two alfalfa cultivars (bami and hamedani) to six levels of water salinity (0, 25, 50, 75, 100, 125 mm l-1 nacl), a glasshouse experiment was conducted at the college of agriculture, shiraz university, shiraz, iran in 2008. the results showed that in bami (which appeared...

This paper studies two types of attacks on the hash function Shabal. The first attack is a low-weight pseudo collision attack on Shabal. Since a pseudo collision attack is trivial for Shabal, we focus on a low-weight pseudo collision attack. It means that only low-weight difference in a chaining value is considered. By analyzing the difference propagation in the underlying permutation, we can c...
