Evaluation of Ketamine Hydrochloride in Combination with Midazolam, Dexmedetomidine and Butorphanol as Balanced Anaesthesia in Cats

Background: As cats undergo stress at the time of presentation before surgery and therefore sedation is required often. It is very difficult to choose a balanced anaesthetic protocol during the surgical intervention in the case of a cat. Therefore, the present study was undertaken to evaluate the effect of ketamine hydrochloride in combination with midazolam, dexmedetomidine and butorphanol as balanced anaesthesia on clinico-physiological, haematological, serum biochemical profile in the surgical management of cats undergoing neutering. Methods: The study was performed on 18 clinical cases of cats which were brought to the Teaching Veterinary Clinical Complex, College of Veterinary Sciences and Animal Husbandry (CVSc and AH), Central Agricultural University (CAU), Selesih, Aizawl, Mizoram for elective surgery such as neutering. Cats were randomly divided into 3 equal groups, i.e. Gr. A, Gr. B and Gr. C. Animals were premedicated with glycopyrrolate @ 0.01 mg/kg, i/m. After 10 minutes of premedication, in Gr. A ketamine hydrochloride @15 mg/kg and midazolam @ 0.5 mg/kg, in Gr. B ketamine hydrochloride @10 mg/ kg and dexmedetomidine@ 5 mcg /kg and in Gr. C ketamine hydrochloride @ 5 mg/kg, dexmedetomidine@ 5 mcg/kg and butorphanol @ 0.2 mg/kg was administered intramuscularly. Clinico-physiological and haemato-biochemical profiles were evaluated at 0 minute (baseline), then at 15, 30 and 60 minutes after administration of anaesthetic agents to evaluate their anaesthetic effect. Result: In the case of time for induction, the quality of induction, assessment of peri-operative analgesia, depth of anaesthesia and quality of recovery there was no significant difference among all three groups. In Gr. B, animals showed significantly higher duration of recumbency (DOE) and recovery. The assessment of peri-operative analgesic effect among the groups revealed that analgesia during the perioperative period appeared best in Gr. C protocol. In regards to depth of anaesthesia, ketamine hydrochloride in combination with dexmedetomidine and butorphanol group showed a better result. Rectal temperature decreased significantly (P greater than 0.05) up to 60th minutes in Gr. A, but it remained within the physiological range. Heart rate raised significantly (p less than 0.05) from the baseline (0 minutes) onwards and decreased significantly (p less than 0.05) till the end (60 minutes) of the study in Gr. C. The respiration rate was significantly (p less than 0.01) different in between time intervals for all three groups. No significant difference was observed on haemato-biochemical observation except glucose level which significantly increased after induction of anaesthesia. In conclusion, treatment with ketamine hydrochloride in combination with dexmedetomidine and butorphanol led to acceptable sedation and mild changes in clinico-physiological, haematological, serum biochemical profile in comparison to the other two groups.

​Genital Changes, Haemato-biochemical Profile and Therapeutic Management of Endometritis in Crossbred Dairy Cows

Background: Reproductive performance is one of the major determinants for the economic improvement of a dairy farm. Endometritis and other uterine complications cause decrease the pregnancy rate. In this study, the genital changes and haemato-biochemical profile of crossbred dairy cows affected with endometritis was studied to evolve a suitable treatment protocol in order to improve reproductive efficiency. Methods: Crossbred cow affected with endometritis were selected based on mucopurulent vaginal discharge at estrus and tested positive for white side test. Animals were divided randomly into 8 groups with 24 animals in each group. Different therapeutic regimens fortified with supportive treatment were opted. The therapeutic regimens were supportive therapy having bypass fat, vitamins and minerals, Lugol’s iodine, Lugol’s iodine with supportive therapy, intrauterine (IU) antibiotic, IU antibiotic with supportive therapy, E. coli. LPS, E. coli. LPS with supportive therapy and control group respectively. Efficacy of each treatment regimen was based on first service conception rate (FSCR). Result: Of all the therapeutic regimens, fortification of Lugol’s iodine with supportive therapy resulted in higher FSCR (83.33%) indicating better applicability as a treatment tool for endometritis in crossbred cows.

Laboratory-Based Cytological and Biochemical Profile of Cerebrospinal Fluid for Children With Acute Bacterial Meningitis in Bangladesh

An attempt was made to analyze the cerebrospinal fluid (CSF) for a cytological and biochemical profile to identify etiological agents from children with suspected acute bacterial meningitis. The cerebrospinal fluid (CSF) samples from 371 suspected meningitis cases were examined, and the highest bacterial meningitis was found in 52(14.0%) cases in this study. Among a total of 371 samples of CSF, 272(73.3%) were crystal clear, 52(14.0%) were moderately turbid, 47(12.7%) highly turbid. The total leukocyte cell count of the CSF was proportionate to the turbidity. In the case of crystal clear CSF’s, total leukocyte counts (TLC) were normally ranging from <5 to 45 per mm3 with predominant lymphocytes. Moderately turbid fluid showed 46 to 500 cells per mm3 and highly turbid fluid showed from 501 to more than 10,00 cells/mm3. In the latter cases, differential counts demonstrated polymorphonuclear predominance. In addition, about 100% (52 cases) of positive and 12.5% (40/319) of negative cases had CSF protein concentration >100 mg/dL. CSF protein concentration greater than 100 mg/dl and sugar level below 40 mg/dl were considered as suspected bacterial meningitis in this study. Surprisingly, the C-Reactive Protein (CRP) values were found to be >40 mg/dL in both culturally positive and negative cases. Most of meningitis positive cases showed increased total cell counts as well as protein concentration, and decreased serum sugar concentrations. J. Asiat. Soc.

The Role of Feed Restriction on DNA Methylation, Feed Efficiency, Metabolome, Biochemical Profile, and Progesterone Patterns in the Female Filial Generation (F1) Obtained From Early Feed Restricted Ewes (F0)

Deficient management of replacement animals in the farm during early developmental windows may promote adverse programming effects on reproductive traits and subsequent transmission to the next generation. In this sense, DNA methylation profiles allow researchers to decode epigenetic regulation mechanisms in mammals and identify novel candidate genes correlated with phenotype differences in both dams and offspring. Therefore, improving knowledge in the field of epigenetics and intergenerational effects caused by prenatal and postnatal early nutritional events (e.g., feed restriction) is crucial for refining strategies dedicated to animal breeding. In this study, we determined differences in the global blood methylation patterns, biochemical profile, and metabolome of ewe lambs (F1) born from either early feed restricted dams (F0-RES) or fed ad libitum (F0-ADL). Our data show that functional categories such as those related to cellular processes, phosphorylation, nervous system, immunity response, or reproductive function were enriched significantly in the F1-RES lambs due to differences in the methylation of genes in these categories. These F1-RES lambs did not show differences in feed efficiency during the replacement period but presented higher levels of insulin and triglycerides and reduced concentration of progesterone, whereas the metabolome profile demonstrated variations in the bile acid composition when compared with the F1-ADL lambs. Taken together, all these results suggest that intergenerational effects caused by early feed restriction of dams (F0) may persist in the F1 female lambs with negative consequences on genes involved in cellular processes and reproductive traits.

Dampak Trichinella sp. dalam Daging Babi Terhadap Kesehatan Masyarakat

Trichinellosis/Trichinosis is one of the most common zoonotic parasites in the world caused by infection with Trichinella nematodes. The infection occurs after the larvae have been eaten in the muscles of the infected animal. Due to its spread and spread, several outbreaks of trichinosis have occurred around the world, which has caused serious public health problems. The main risk factor for trichinosis is the consumption of raw or undercooked meat from pigs and hunted meat. In the first stage of infection, adults nematode in the intestine can cause transient gastroenteritis, but the most serious symptoms are associated with the larval formation and muscle migration. a study conducted in India to investigate at the clinical and biochemical profile of Trichinella infection stated that clinical symptoms first appeared at 2-3 weeks after consuming pork and the symptoms would gradually disappear at 4-5 weeks, but there were also some who experienced myalgia. Supervision and implementing proper biosecurity in livestock areas by monitoring and surveillance of the risk of Trichinella infection in pig products and their derivatives as well as preventing transmission to humans.

Ancient Wheat Species: Biochemical Profile and Impact on Sourdough Bread Characteristics—A Review

In recent years, the attention of farmers, bakers and consumers towards ancient wheat species has been increasing. Low demands of pedo-climatic growth factors, the suitability for organic cultivation along with their high nutritional quality and their content in pro-health compounds make them extremely attractive for bakers and modern consumers, equally. On the other hand, in recent years, sourdough has gained attention due to its ability to produce new functionally active molecules with higher bioaccessibility and thus to produce bread with enhanced nutritional quality. This paper highlights the relevant nutritional profile of einkorn, spelt, emmer and Khorasan which could lead to bread with improved textural, sensorial, microbial and nutritional characteristics through sourdough fermentation. The ancient wheat species could be used as promising substitutes for common wheat flour for the design of innovative types of bread, even for special needs.

Inclusion of milled canola grain in the diet of broilers

The effect of milled canola grain (MCG) in the diet of broiler chickens, from 1 to 42 days old, on performance, organ weight, biochemical profile, and carcass yield was evaluated. A total of 660 one-day-old male Cobb® broilers were distributed in a completely randomized design with six levels of inclusion of MCG in the diet (0; 5; 10; 15; 20, and 25%), totaling six treatments with five replicates of 22 birds. The canola used for the experiment was ground using a hammer mill with a 4.5 mm sieve to obtain a DGM of 955 µm. Performance data, organ index, blood biochemical profile, carcass yields, and cut up weights were evaluated. The data were analyzed by analysis of variance (ANOVA), and when there was significance Dunnett’ test was used to compare the inclusion levels the control diet. An effect was seen on mean weights and on feed conversion based on the inclusion level of MCG in the diets. The birds that received 20 and 25% inclusion of canola in the diet presented a worse performance in relation to that of the control. For the other variables analyzed, no effect of the treatments was observed when compared with the control (p > 0.05). It was concluded that the inclusion level of MCG in the diet of up to 15% can be used without losses to the performance of birds and without influencing the metabolism of the birds.

Effects of Periodic Religious Fasting for Decades on Nutrient Intakes and the Blood Biochemical Profile

The aim of the present study was to examine differences and correlations in nutrient intakes and serum parameters related to nutrient intake (lipid profile, vitamins, and trace elements) in 200 lifelong Christian Orthodox Church (COC) fasters with periodic abstinence from certain foods (predominantly of animal origin) for approximately half of the year and 200 non-fasting controls, all of whom did not take dietary supplements. Nutrient intakes were assessed through three-day dietary recalls. Blood samples were drawn for the analysis of potential biomarkers of nutrient intake. Fasters had lower energy intake, due to lower fat and protein intake, compared to non-fasters (p < 0.05). Fasters also had lower intakes of vitamins A, B1, B2, B6, B12, D, folate, pantothenate, sodium, calcium, zinc, and phosphorus. Most participants (in both groups) did not meet the recommended dietary allowances of most vitamins and elements. Most serum biochemical parameters did not reflect the differences in nutrient intakes between groups, and none exhibited a correlation coefficient above 0.5 with nutrient intakes. Our findings suggest that COC fasting is associated with reduced intake of many nutrients, although this does not seem to have an impact on the blood biochemical profile.
