A study was conducted to determine the effects of water temperature and rations size on growth performance, feed utilization and carcass biochemical composition of juvenile Benni. Six treatments representing a combination of two water temperature (24 and 28 °C) and three feeding rations (1%, 3% and 5%) were tested with three replicates. Each replicate was stocked with 12 fish (30.66±0.81 g aver...

A feeding trial of 120 days duration was conducted to study the effect of replacing 20 and 25 % of camel ration by poultry litter (PL) on the performance and some blood biochemical parameters. Fifteen healthy one–humped camels were allotted into three groups (5 animals / group). The first group was fed a basal ration and considered as control, while the second and third groups were fed rations ...

previous work by other investigators indicates a direct relation between the amount of protein in the diet and the level of urea in the blood . however, the present report shows that the type of protein , apart from its level in the ration , also has an effect on blood urea concentrations. when adult male or female rats of two strains were fed a ration in which the only source of protein was wh...

I . Four wether sheep, each fitted with re-entrant duodenal cannulas and a rumen cannula, were used to determine the relative quantitative importance of digestion in the stomach compared with that in the intestines when diets of low (HMI) and high starch (CMI) content were fed at 0.9 times maintenance and when the high-starch diet was fed at 1.7 (CMz) and 2.3 (CM3) times maintenance. Paper, imp...

Coronary atherosclerosis developed in normolipemic swine fed a basal ration supplemented with 125,000 IU, 62,500 IU and 31,250 IU of vitamin D3/kg of diet for 3 months and subsequently only the basal ration for the following 3 months. Lesions consisted of intimal atheromata and calcified internal elastica and caused luminal narrowing. The incidence of atherosclerotic lesions was proportional to...

In a brief preliminary report’ we described a faulty ration and its effects on t,he skeleton of the growing rat, which corresponded in all essential details to rickets as that disease manifests itself in the skeleton of the human being. The faulty ration in question, No. 3127, was deficient in phosphorus and fat-soluble A.2 In other respects it was, apparently, satisfactorily constituted. It co...

p ERRY et al. (1957)and Neumann (1960) reported that steers fed an all-concentrate ration developed vitamin A deficiency even though carotene was present in the diet in excess of requirements (N.R.C., 1958). Jordan et al. (1963) found similar results when steers were fed principally on corn silage. Steers fed a "high" nitrate silage were depleted of their liver vitamin A reserves more rapidly t...

Man-hour ration is an important work in process planning, it influences on the production cost and production plan. According to the practical requirements of rotary bearing manufacturing enterprise, a function framework of man-hour ration management system is proposed in the paper. Some key techniques are discussed, involving UML modeling, man-hour calculation method based on the general proce...

the effect of temperature on the main feeding parameters of mnemiopsis leidyi from the southern caspian sea was studied in 2002. the clearance rates and daily rations were estimated from laboratory experiments in a wide range of temperatures from 12 to 27 ?c for m. leidyi of 12?17 mm in length. clearance rate values changed from 52.5 to 107.3 ml ind-1 h-1. the coefficient q10 in temperature 12 ...

The influence of nutrition during the last trimester of pregnancy and the early postpartum period on postpartum LH secretion was evaluated in two-year-old Hereford and Simmental heifers maintained on a high or low plane of nutrition (experiment 1) or in Hereford heifers fed a high or low energy (150% vs 100% NRC) ration (experiment 2). Amount of LH released with 10 mg estradiol benzoate (IM) at...
