EFFECT OF SUPPLEMENTAL RATION ON CHANGES IN BLOOD COMPONENTS OF STEERS GIVEN ACCESS TO LUSH PASTURE

Prepasture feeding of low quality hay versus hay and grain had no subsequent effect on rumen fluid ammonia, blood urea, or plasma calcium, glucose and lactic acid concentration in steers turned out on lush pasture. Steers previously fed hay and grain had lower plasma magnesium levels on the first day on unsupplemented pasture than those fed hay prior to pasture. Supplemental feed on pasture partly alleviated the depression in plasma magnesium on the first day on pasture. Feeding supplemental hay with pasture tended to lower rumen fluid ammonia, blood urea and plasma lactic acid compared with feeding no supplement during the initial days on pasture, indicating the desirability of hay feeding during this time. A hay and grain supplement with pasture had a similar effect to the hay supplement on rumen-fluid ammonia, and plasma lactic acid, but a lesser effect on blood urea concentration. Neither supplemental hay nor hay plus grain affected plasma calcium or glucose levels. All steers showed an increase in rumen fluid ammonia, blood urea and plasma lactic acid on the first day and a decrease in plasma calcium and magnesium on the second day on pasture. Blood urea, plasma magnesium and plasma calcium concentrations had not returned to prepasture levels by 21 days on pasture.

Muriate Of Potash

1. Muriate of potash applied at rates of 0, 1 and 2 cwt./acre to herbage which had also received similar treatments in the previous year did not influence plasma magnesium or calcium values in lactating ewes.2. 24 Cheviot ewes had slightly lower plasma calcium and magnesium levels than 24 Half-bred ewes of the same age both before and after lambing.3. 6·6 g. of magnesium oxide given as a daily drench did not increase plasma magnesium values as measured by blood samples taken 24 hr. after drenching. Values were however increased by 0·5 mg. Mg/100 ml. four hours after drenching.4. No clinical cases of hypomagnesaemic tetany occurred, even although the mean plasma magnesium level of all the ewes in the experiment was only about 1·0 mg./lOO ml.5. Plasma magnesium values of ewes before lambing were significantly (P < 0·001) correlated with post-lambing levels. Values for the ewes during 1962 were equally significantly correlated with levels for the same sheep at comparable dates in 1961.

2. Rumen fluid was sampled before feeding from cows given hay, diluted with an anaerobic salt solution and added (20 ml) to different amounts (mostly 1 g) of maize gluten meal, maize, citrus pulp, tapioca, beet pulp, coconut expeller or soya bean oilmeal for incubation at 39 deg C. After at least 4 h of incubation there were large differences in pH and lactic acid concentration. The acidotic index of the feeds was influenced by increasing concentration of the substrate. Except with maize meal, there was little effect of particle size on pH and lactic acid concentration. There were differences in effect on pH and lactic acid concentration between different batches of the same feeds, especially with maize meal. Incubations with mixtures of concentrate ingredients showed different pH and lactic acid concentrations from values expected from results with the single ingredients.

This study was conducted to investigate the effect of malic acid and 20% palm kernel meal (PKM) on ruminal characteristics. A total of 32 growing lambs were randomly distributed into control (barley and alfalfa ha), total mixed ration (T1), TMR + 20% PKM (T2), TMR + PKC 20% + 4 mL/day malic acids (T3). Lambs were fed these diets ad libitum for 84 days. The results showed that propionic acid in the rumen fluid increased significantly (p < 0.05) in T1 and T3. Lactic acid concentration of rumen fluid increased significantly (p < 0.05) in T2 while the pH increased significantly. The coloration of rumen and reticulum was improved in T3. In addition, most of the histomorphological features were higher in T3 and T2. We concluded that the addition of malic acid supplementation to lambs fed PKC caused a significant improvement in the rumen pH and decreased lactic acid concentration in growing Naemi lambs.

1. An experiment is described which investigated the effects of potassium fertilizer, age of ewe, and a small magnesium supplement, on the plasma magnesium and calcium levels of ewes shortly after lambing.2. Three potassium treatments (0, 1, and 2 cwt. muriate of potash/acre) were used, each being replicated six times, which gave a total of eighteen plots. Each plot was grazed by two old and two young ewes. One ewe of each age in every plot was given supplementary magnesium in the form of two magnesium heavy pellets, which released a total of 150 mg. Mg/day.3. 22% of the ewes had plasma magnesium values below 1·0 mg. Mg/100 ml. on at least one sampling occasion during the experimental period. There was only one clinical case of tetany.4. Neither potassium fertilizer use, nor magnesium supplementation influenced plasma magnesium and calcium levels of the ewes. Old ewes had greater temporary falls in plasma magnesium values and had consistently lower plasma calcium values.5. Attention is drawn to the large individual variation between animals and the consequent need for providing adequate statistical analysis of experiments of this type.

Plasma Magnesium

Recent investigations suggest that there may be an abnormality of calcium and magnesium in depressive illness. Flach (1964) followed the urinary excretion of calcium in depressed patients maintained on a constant intake of calcium before and during recovery. Those patients that recovered showed a significant decrease in the excretion of calcium. Coiraultet al.(1959) reported an increase in ionized calcium and a decrease in total plasma calcium on recovery from depression. Cade (1964) reported considerably raised total plasma magnesium levels in depressed patients both before and after recovery. A connection between affective disorders and calcium metabolism is suggested by the common occurrence of such states in both hypo- and hypercalcaemia (Denco and Kaelbling, 1962; Rookus and Speelman, 1961). The present paper reports an investigation into total and ionized plasma calcium and magnesium in a group of depressed patients both before and after recovery. The effects of lithium carbonate, a compound used in the treatment and prophylaxis of affective disorders (Baastrup and Schou, 1967; Schou, 1963) on plasma concentrations of magnesium and calcium was also investigated.

This study aims to investigate the influence of concentration and soaking time of lactic acid toward glucose and quality of canna’s starch (Canna Edualis Kerr). The research method using a completely randomized design (CRD) with 3x3x3 factorial and three replications. The repetition are K1L1, K1L2, K1L3, K2L1, K2L2, K2L3, K3L1, K3L2, first K3L3. The first factors is variations of concentration (K) include 1%, 1.5%, 2%, the second factor is soaking time (L), there are 60 minutes, 90 minutes, 120 minutes. Collecting data by calculating the glucose level using titration method with Na. Organoleptic tests include color, odor, texture and level of preference to the 15 panelists using a closed questionnaire. Best organoleptic test are K3L3 treatment (2% of lactic acid concentration with 120 minutes soaking time) with a total value of 82.5 while the lowest are K3L1 treatment (2% of concentration with a 60 minutes of soaking time) with 48.5 of values. Data analysis shows the variation of concentration affect on glucose levels (P = 0.000 <0.05). Soaking time affect on glucose levels (P = 0.000 <0.05) .There are any interaction effect of concentration and soaking time on glucose levels. Based on the results showed that the highest glucose levels found in K1LI treatment with 1% of lactic acid concentration and 60 minutes of soaking time. As for the glucose concentration was lowest for K3L3 treatment with 3% of lactic acid concentration and 120 minutes of soaking time. The results of this study are used as material preparation Biochemistry lab manual.

Concentrate ingredients (maize meal, coconut oilmeal, maize gluten feed, citrus pulp, tapioca and soya bean oilmeal) were given daily at 0900 h into the rumen of 4 cows for 5 successive days. Hay was given freely at 1300 h. Between experimental periods there were intervals of at least 17 days when hay was given at 0800 and 1700 h. In a second experiment 6-kg amounts of 1:1 mixtures of 2 ingredients were given. Lowest pH and highest concentrations of D- and L-lactate in rumen fluid were reached 2 to 3 h after ingredients were given. Lowest pH and highest D- and L-lactate concentration in rumen fluid relative to the situation after citrus pulp was given, taken together as the potential risk of lactic acid acidosis (RLA), was best correlated with the content of glucose plus fructose (GF) and soluble protein (SPROT); RLA = 1.47GF + 0.49SPROT + 22.50 (r = 0.89). When combined ingredients were given, pH and D- plus L-lactate concentrations differed from values calculated from results after the same ingredients had been given separately.

ABSTRACT Intravenous infusion of isotonic magnesium chloride into young cats with a resultant mean plasma magnesium concentration of 7.7 meq./100 g protein was followed by a significant lowering of the plasma calcium concentration in 90 minutes. The rate of decrease of plasma calcium is consistent with the hypothesis that calcitonin is released by magnesium in high concentrations. There was no decrease in the plasma calcium concentration in cats of the same weight thyroparathyroidectomized 60 min before an identical magnesium chloride infusion or an infusion of isotonic sodium chloride at the same flow rate. The hypercalciuric effect of magnesium could not account for the hypocalcaemic effect of magnesium. Plasma magnesium concentration during magnesium infusion into cats with an intact thyroid-parathyroid gland complex was slightly, but not significantly higher than in acutely thyroparathyroidectomized cats.
