of the animals. Grade 3 lesions (corneal ulceration) were observed in 2% of the calves but few animals had irreversible damage. Only 2% of animals had keratoconus with ocular substance loss (grade 4) which caused permanent blindness (Fig. 3A). Among the calves which presented lesions in one sampling, most showed signs of improvement during subsequent observations with total remission of the... beef herd with a high prevalence of lesions caused by Mb. Sampling was carried out in six stages and included conjunctival swabs for isolating Mb as well as blood samples for identifying antibodies specific for BHV-1. A score for IBK lesions after observing each eye was determined. The findings of this study showed a high prevalence of BHV-1 virus infection (100% of animals were infected at the end of the trial); 67% of animals were culture-positive for Mb, but low rates of clinical IBK (19% of... -

Lead content was determined by inductively coupled plasma atomic emission spectrometry. Of the 60 analyzed samples, 21 had values greater than 30 ppm (range less 1.6 to 460 ppm), which is the maximum concentration recommended [3,14]. These findings show the necessity for careful industrial monitoring because some mineral mixtures contain sufficient lead to cause toxicity in animals. -

the highest quality grade (only grade 1) according to the Guide of the International Embryo Transfer Society [17]. On day 7, a single blastocyst was loaded into the medium designed through the pilot experiments and transferred nonsurgically to the uterine horn, ipsilateral to the corpus luteum of each recipient. For pregnancy diagnosis, recipients who did not return to estrus were initially... Bovine embryos (day 5) were cultured to day 10 with or without 100 ng/mL PGF2α in medium supplemented with control; 100 nM Dex; 1,000 U/mL recombinant human leukemia inhibitory factor (rhLIF); or Dex+rhLIF. Although the rates to development to the blastocyst were not significantly different among groups, the hatching rate after additional culture with Dex +/or rhLIF was significantly higher in all supplemented groups than the control (p ＜ 0.05). In the presence of PGF2α, the hatching rate was... -

The body condition score (BCS) system is a subjective scoring method of evaluating the energy reserves of dairy animals to provide better understanding of biological relationships between body fat, milk production and reproduction. This method helps in adopting the optimum management practices to derive maximum production and maintain optimum health of the livestock. In this study, a new BCS system was developed for Murrah buffaloes. The skeletal check points were identified by studying the... -

μl of 100% HPLC grade methanol (Sigma-Aldrich, Germany) by vortexing. Samples that were not analyzed were immediately stored at -20 o C until analysis. Extracted AFB1 samples were diluted with 70% methanol and aflatoxin assay was done using the AgraQuant Total Aflatoxin Test Kit (4-40 ppb) (Romer Labs, Singapore). Sample assay procedure One hundred μl of aflatoxin test kit standards (0 ppb,... The aflatoxin B1 degrading abilities of two different ruminants were compared in this study. One set of experiments evaluated the aflatoxin B1 degradation ability of different rumen fluid donors (steers vs. goats) as well as the rumen fluid filtration method (cheese cloth filtered vs. 0.45 Ռm Millipore) in a 2 × 2 factorial arrangement. Additional studies examined aflatoxin B1 degradation by collecting rumen fluid at different times (0, 3, 6, 9 and 12 h) after feeding. Cannulated... -

with graded doses of chromium Laboratory reagent grade chromium chloride hexahydrate (CrCl 3. 6H2O; Hi-Media Lab, India; molecular weight 266.45; minimum assay 97%) was the source of supplemental Cr (molecular weight 52) in this study. A solution containing 1.0248 mg CrCl 3. 6H2O equivalent to 0.2 mg elemental Cr was prepared by dissolving 512.4 mg CrCl 3. 6H2O in 500 ml triple distilled water. 1... Black Bengal bucks (Capra hircus) were supplemented with 0, 0.2 or 0.4 mg elemental chromium (Cr) as chromium chloride hexahydrate per day for 70 days. Intake of dry matter (p <0.001), crude protein (p < 0.001) and neutral detergent fiber (p <0.01) increased due to Cr supplementation. The apparent total tract digestibility of dry matter (p <0.01), organic matter (p <0.05), crude protein (p <0.001) and acid detergent fiber (p <0.01) improved and the total body weight gain and the live weight gain... -

Macrolides are frequently used in veterinary medicine as therapeutic and preventive agents for various diseases. It is difficult to determine macrolides simultaneously with conventional methods due to their similar structures. A simultaneous analysis for erythromycin, roxithromycin, tiamulin and tylosin with LC/MS has been developed. Separation was performed on C18 reversed phase column. Mobile phase was gradiently flowed with 10 mM ammonium acetate and methanol. The mass spectrometer was run in...
