RESUMO
PURPOSE: The feeding value and nutritional adequacy of two cereal fodder, viz. sorghum (Sorghum vulgare) and maize (Zea mays), were evaluated in spotted deer (Axis axis) and compared with that in sheep in two consecutive feeding trials of 35 days each. METHODS: Four spotted deer (2 years of age, 68.3 kg average body weight) and six sheep (1.5 years of age, 18.0 kg average body weight) were fed on the above two fodder types as sole feed. Nutrient digestibility and evaluations were made through two digestion studies that ended with each feeding period. RESULT: Both sorghum and maize fodder provided 11% CP and 4.4 kcal DE per gram of TDN in the two species studied. A lower intake of DM (40.6 vs 47.5 g/kg(0.75)) and other nutrients was observed in deer during maize feeding period. It was similar but lower in sheep compared to deer. The digestibility of nutrients from both fodder types was higher in deer (66-77%) than sheep (45-62%). Numerically, most of the nutrients from sorghum fodder were better digested than maize except CP and EE. Maize fodder provided a higher percentage of NDF (70.85% vs 67.90%) and ADF (37.22% vs 30.74%) with a digestibility depression of about two units in deer and three to five units in sheep. Deer and sheep lost body weight during both the sorghum (2.0 and 0.7 kg) and the maize (2.5 and 0.4 kg) feeding periods. CONCLUSION: Although the nutritive value of cereal fodder seemed optimum, a lower voluntary feed intake in both deer and sheep contributed to inadequate nutrient intake compared to standard recommendation.

Data from 27 feeding trials conducted on growing pigs from different research institutes across India were subjected to mixed model regression analysis to derive requirements of digestible energy (DE), crude protein (CP) and essential amino acids for maintenance and body weight gains. The ranges of maintenance requirements were determined to be: DE 516 to 702 kJ/kg M0.75, CP 6.98 to 11.62, lysine 0.431 to 0.664, methionine 0.265 to 0.458, methionine + cystine 0.327 to 0.466, cystine 0.055 to 0.184, threonine 0.205 to 0.511, arginine 0.377 to 1.21, isoleucine 0.241 to 0.775, leucine 0.604 to 1.54, phenylalanine + tyrosine 0.496 to 1.33, tryptophan 0.078 to 0.213, and valine 0.330 to 0.892 g/kg M0.75, respectively for different body weight ranges. The corresponding requirements for 1 g gain in body weight were: DE 28.6 to 38.6 kJ, CP 0.27 to 0.44 g, lysine 0.0071 to 0.0126 g, methionine 0.0047 to 0.0133 g, methionine + cystine 0.0151 to 0.0261 g, cystine 0.0043 to 0.0094 g, threonine 0.0052 to 0.0165 g, arginine 0.0045 to 0.0301 g, isoleucine 0.0023 to 0.0198 g, leucine 0.0150 to 0.0447 g, phenylalanine + tyrosine 0.0091 to 0.0382 g, tryptophan 0.0005 to 0.0044 g, and valine 0.0061 to 0.0222 g. Regression equations had high R2 values (ranging from 0.50 to 0.99 for different estimates), low coefficients of variation, low variance of error estimates and the coefficients were highly significant (P < 0.001). Regressed values were used to develop feeding standards. As the new standards derived in the present study are based on a thorough analysis of a larger database than previous Indian standards, the new feeding standard seems to be more appropriate for India and other tropical countries.
RESUMO
A survey was conducted in 10 districts of Northern India to record the copper deficiency in soil, fodder and serum samples. Significant deficiency of copper was observed in soil, fodder and serum samples of heifers. The copper deficient animals were listless, showed depigmentation of skin, stiff gait and were anaemic and diahorric. The purpose of the study was to evaluate the magnitude of copper deficiency in Northern India and to examine the various haematobiochemicals, enzymes, vitamin and immune function which are affected by the deficiency of copper, so as to identify the parameters which can be of diagnostic importance in copper deficiency. Forty hypocuperemic heifers were selected from these areas and were randomly divided into two groups A and B. The heifers in group A were provided with mineral mixture containing copper sulphate and in group B without copper sulphate. Significant improvement (P<0.01) was observed in the haemoglobin (Hb), total leukocyte count (TLC) and total erythrocyte count (TEC) level at the 30th day of treatment in the animals of group A. Significant (P<0.01) improvement in serum. Ceruloplasmin (Cp) level was observed within 30 days of treatment, while significant (P<0.01) improvement in monoamine oxidase and liver cytochrome oxidase was observed at the 60th day of treatment in group A animals. Regarding hormones significant improvement was observed in T(3) and T(4), in the animals of group A within 60 days of treatment. The values of vitamin A and E showed significant (P<0.01) improvement within 30th days of treatment. The phagocytic activity of neutrophils against Candida albicans significantly (P<0.01) improved in group A within 60 days of treatment. Similarly significant improvement in superoxide dismutase activity in RBC was observed at the 30th day, and WBC and whole blood at 60th day in group A animals. Significant improvement in liver Cu level was observed at the 30th day of treatment, while in group B the liver Cu was significantly (P<0.01) depleted at the 60th day of experimentation. Additional Cu supplementation improved growth performance significantly in group A.

In a 2 x 2 factorial design, 24 newborn, crossbred (Bos indicus x Bos taurus) calves were distributed in 4 equal groups involving dietary treatments of prestarter diets with (FM) or without fish meal (NFM) in a faunated (F) or ciliate-free (D) ruminal environment to study the ruminal fermentative development in pre-and postweaning periods. Defaunation was achieved by rearing calves in isolation and its effect was studied after first appearance of ciliate protozoa (observed after 8 wk of age) in the faunated animals. Calves were fed colostrum for 24 h and whole milk until weaning at 8 wk of age. Ruminal content samples were collected on d 4, 1 wk, weekly to 8 wk, and then biweekly at 9, 11, and 13 wk of age. The samples were analyzed for fermentation products [pH, total volatile fatty acids (VFA) and ammonia N] and enzyme [carboxymethyl (CM) cellulase, xylanase, beta-glucosidase, alpha-amylase, beta-galactosidase, proteases, and urease] activities. Weekly feed intake increased with age, but was similar in both groups. Ruminal pH declined steadily during 0 to 4 wk of age and then stabilized. The total VFA concentration increased with the age. The ammonia N (mg/dL) concentration increased from 14.9 on d 4 to 32.4 at 4 wk, decreased to 17.6 at 8 wk, and then steadied during the postweaning period. Samples collected on d 4 had no fibrolytic activity. Xylanase (U/dL) appeared first (1 wk) followed by beta-glucosidase (U/dL) and CM cellulase (U/dL), which increased steadily from a low of 4.69, 0.08, and 2.95 to 31.8 (6 wk), 5.92 (7 wk), and 19.8 (8 wk), respectively, and the concentrations showed nonsignificant alterations during postweaning periods. The concentration of alpha-amylase (U/dL) increased from 34.3 on d 4 to 87.2 at 8 wk, and then decreased to 56.6 (13 wk). beta-Galactosidase increased up to 6 wk then decreased to trace level (0.20 U/dL) at 13 wk of age. The concentrations of proteases and urease reached a steady state after 1 wk of age. The effect of diet type on ruminal fermentation products and enzyme parameters was nonsignificant. However, a steady and proportional alteration in both parameters in response to dry feed intake with the advancement of age was seen in all calves. Defaunation increased total VFA (97.3 vs. 75.8 mM/L) and alpha-amylase activity (80.3 vs. 61.4 U/dL) and decreased ammonia N (16.4 vs. 21.1 mg/dL), whereas the effect on other parameters was nonsignificant. Ruminal fermentative changes responded to dry feed intake, but did not differ in response to animal protein in prestarter diet.

AIMS: To test various microbial cultures as cattle feed additives. METHODS AND RESULTS: Four groups of newly born crossbred calves (average body weight 23.5 kg) were reared on green berseem and calf starter which was devoid of cereal grains. Milk was fed up to 8 weeks of age, starting with one tenths and gradually reducing to one twentieths of the body weight. One hundred millilitres of microbial feed additive or 100 g fermented feed was fed to the animals of group 2 (curd containing lactic acid bacteria at 10(8) cfu x ml(-1)), group 3 (Saccharomyces cerevisiae NCDC-49 at 10(6) cfu x ml(-1)) and group 4 (Lactobacillus acidophilus-15 at 10(8) cfu x ml(-1)). Group 1 served as control. The incidence and duration of diarrhoea was lower in the animals of probiotic fed groups as compared to control group. Out of three microbial feed additives, yeast feeding showed maximum suppression of diarrhoea followed by Lactobacillus and curd. CONCLUSIONS, SIGNIFICANCE AND IMPACT OF THE STUDY: There was no effect of probiotic feeding on the log number of cells of lactic acid bacteria, yeast and coliform bacteria in the faeces and rumen liquor at any age. The activities of carboxymethylcellulase, xylanase, beta-glucosidase, alpha-glucosidase, alpha-amylase, protease, urease and pH of the rumen liquor remained unaffected by probiotic feeding at all ages tested in this experiment.

Eight 6-9 month old calves, showing clinical signs of intermittent haemoglobinuria, even after treatment with an antipiroplasmal drug (4,4-diamidinodiazaminobenzene diaceturate), were examined for oxidative damage to their erythrocytes and the presence of hemoprotozoa in blood smears. Four calves without signs of haemoglobinuria served as controls. The blood smears from three of the eight calves contained piroplasms for Theileria annulata. Irrespective of the presence of piroplasms in their blood smears, the calves with haemoglobinuria had significantly (p < 0.01) lower haemoglobin concentrations (Hb) and packed cell volumes (PCV). The lipid peroxide level in the erythrocytes, but not in the plasma, of calves with red urine was significantly (p <0.05) higher than that for the controls. It is concluded that haemoglobinuria, irrespective of the presence of piroplasms in blood smears, is associated with oxidative stress to erythrocytes and peroxidation of polyunsaturated fatty acids of cell membrane.

Effect of lactobacillus supplementation was studied in eight Mongrel pups of about 10 weeks of age with a mean body weight of 5.2 kg divided into two equal groups, control (group C) and a probiotic supplemented group (group L). Both groups received the same feed (biscuit) which was for group L supplemented with 2 x 10(7) cfu of a Lactobacillus acidophilus strain. The feeding trial lasted 13 weeks and included a digestibility trial of six day during which feed and faeces were collected to assess intake and digestibility of nutrients. Growth was recorded as weekly live weight change and the physical, chemical and microbiological characteristics of stool were examined periodically to assess the effect of lactobacillus on intestinal health. The biscuits contained 89% DM, 32.6% CP, 5.8% ash and 12.7% EE with TDN, GE and ME content of 890 g, 19.6 MJ and 14.6 MJ per kg DM, respectively. The DM, OM, CP and GE digestibilities were between 76% to 79% and the EE digestibility was 93%. The CF digestibility was negligible (22%). There were no significant differences between the two groups. There was an appetite stimulation and a relatively higher DM intake (10 to 15%) which induced higher daily gain, 102 g in group L vs. 92 g in group C up to 19 weeks of age, the difference declined thereafter. The average daily gain during the whole period was 74.5 +/- 8.0 g and 81.6 +/- 6.0 g in group C and L, respectively, and the difference was statistically non-significant (P > 0.05). The stools showed similar physical properties and composition with acidic pH in both groups. Lactobacillus supplementation caused a competitive establishment in the gastrointestinal tract of pups. It can be concluded that lactobacillus supplementation shows a positive effect during active growth phase (up to 4.5 months of age), which became insignificant in the later period of life.

Drinking some types of tea and other caffaeinated drink is a part of our culture and everyday life. It is contained from the leaves and seeds of evergreen plant (Camelia thea). It is caffeine contained in so many drinks which really plays havoc with our body and mind. It is only when man exceeds they tea drinking that he experiences the ill effects. When taken in limited quantity tea is indeed very good for health.
RESUMO
Saccharomyces cerevisiae ITCCF 2094, NCIM 3052, 1031, 1032, NCDC 42, 45, 47, 49 and 50 were screened for their tolerance to pH 2.0-7.0, various concentrations (0.00, 0.10, 0.25 0.50 and 1.0%) of a mixture of acetic, propionic and butyric acids (70:20:10), and bile salts (0.00, 0.30, 0.60 and 0.90%). Low pH (2.0-4.0) and addition of organic acids or bile salts in the medium inhibited the growth of all the strains tested, but the percentage of inhibition was variable in the different strains of yeast. Two of the strains showing maximum tolerance, 42 and 49, were further tested for in vitro dry matter degradability (IVDMD) using green berseem, wheat straw and oat hay as substrates. Saccharomyces cerevisiae 49 enhanced the IVDMD of berseem and wheat straw whereas S. cerevisiae 42 was ineffective. Based on the results of the present experiment, S. cerevisiae NCDC 49 can be considered as the best strain which might tolerate the adverse conditions in the gastrointestinal tract when used as a live microbial feed supplement in the diet of the animals.

The three texts written by Charak, Sushrut and Vagbhat are considered as Vrihattrayee because of their original contributions to the basic tenants of Ayurveda and innovative uses of plants and medicine. But despite the possibility of exploring efficacious for mulations from among these classics, not much attempts have been made in this direction, due to the fact that now most of them are not in vogue in practice by majority of Ayurvedic physicians. As such, a glossary of plants as described in those texts for the management of prameha including diabetes has been collected which would be useful for studying these drugs from different angles.

Twenty 9-month-old crossbred calves were divided into 2 equal groups (A and B; n = 10). The feeding trial was conducted for 119 days to study the effect of concentrate supplementation on body immune response and blood metabolites in calves. The concentrate and roughage (wheat straw) ratio in the diet of Groups A and B was 60:40 and 30:70, respectively. Daily dry matter intake was significantly (P<0.01) higher in Group A than in Group B, which also resulted in significantly higher (P<0.01) total body weight gain in the former group. Protein, albumin, globulin, total and differential leukocyte count in blood were similar in the 2 groups but blood glucose level was higher (P<0.05) in the calves of Group A. There was no difference in body immune response between the groups, which indicated that body immune response of animals is not significantly influenced by restricted concentrate feeding.

Different enzymes were tested for isolation of intact protoplasts from pollen tetrads. About 80% isolation was achieved from pollen tetrads of Cajanus cajan and Zea mays and about 60% from Luffa cylindrica and Lycopersicon esculentum after 4 h of treatment with 5% cellulase. When these mononucleate protoplasts were incubated in presence of 0.05 M CaCl2 in 0.3 M glucose at pH 10.5, 70-80% fusion was achieved. Fusion was rare in sodium nitrate solutions.
