2024
K. Naga Raja Kumari | T. Susmita
The study was carried out to evaluate the effect of Saccharomyces boulardii (Sb) on performance and intestinal integrity in broilers. A total of 300 day old Vencobb chicks were randomized in 5 groups, each with 6 replications (5x6) 10 birds per replicate. Groups provided with Sb ( 2 × 108 cfu/kg) in 0,0.02,0.04,0.08 and 0.16 mg/L in D1, D2, D3, D4, D5 respectively through water up to 42 days of age with adlibitum isonitrogenous and isocaloric ration. The results revealed, a significant (p<0.05) improvement in body weight gain, better FCR with increased concentration of Sb in water (D5). No significant variation was observed in feed intake with the level of Sb in water. Intestinal villus height, cryptal depth increased in groups with increased Sb. The results suggest that supplementation of Sb at 0.16mg/L through drinking water improved the performance of the broilers by increasing the absorption capacity in the gut.

M. Anandachitra
Coagulase negative Staphylococci were considered as commensal organisms or contaminants with limited pathogenic potential. However, they are becoming more frequently associated with nosocomial infections in human and skin infections in animals. In this study, we attempted to isolate and identify the Staphylococci species that causes dermatological infections in dogs. Out of 35 isolates, 27 were identified as S.pseudintermedius and 3 as S.schleiferisubspschleiferi. Among three S.schleiferi isolates, 2 were closely related to S.schleiferi ATCC strain in pta gene sequences. Methicillin resistant gene (mecA) was not detected in these isolates. All three isolates were susceptible to oxacillin, amikacin, gentamicin and tetracycline, intermediate susceptibility to ceftriaxone and resistant to Penicillin, ampicillin, sulphadiazine. S.schleiferi is an emerging cause of infections in veterinary patients. None of the isolate produced biofilm in microtitre tissue culture plate adherence method. This is the first report of isolation and identification of S.schleiferi from canine skin infections from India. Further studies are needed for early detection and virulence factors of S.schleiferi in the pathogenesis of pyoderma and otitis in dogs.

The socioeconomic importance of nomadic donkey rearing, perception on health benefits of donkey milk and the marketing channels involved remain unexplored. This paper aims at providing details on nomadic donkey rearing, a traditional system prevailing in Tamil Nadu. Donkey played a significant role in the livelihood of its owners who had migrated throughout Tamil Nadu for selling donkey milk. They traversed around 30 – 40 km per day to sell the donkey milk besides meeting the grazing needs of the donkeys. Majority of the nomadic donkey rearers were young to middle aged and were scheduled tribes. Two third of the respondents were involved in nomadic donkey rearing for nearly eight months in a year and for the remaining four months they earned their livelihood as agricultural labourers. The study revealed that on an average, lactating jenny yield milk for six months. At the end of the lactation period, the donkey rearers sold the dry jenny to the traders and in turn purchased the lactating jenny from them. The nomadic donkey rearers believed that the donkey milk had medicinal benefits to cure ailments such as ulcer, indigestion, pneumonia, jaundice, leukorrhea and hypernatremia. The respondents preferred institutional support in marketing donkey milk so that they could settle in one place and thrive better.

An experiment (97 days) was conducted to investigate the dietary lauric acid (LA) supplementation on performance, digestibility and faecal microflora counts in Large White Yorkshire cross piglets. A basal diet was (BD) prepared as a negative control without supplementation and a positive control with an antibiotic (chlortetracycline at 0.05%) supplementation (BDA). Another two diets were prepared by supplementing LA at 0.2 and 0.4% levels to the basal diet. Dietary inclusion of LA or antibiotic significantly (P<0.01) improved the body weight and feed efficiency and recorded highest (P<0.01) body weights with 0.4% LA, while lowest (P<0.01) weight gain with control group. Significantly higher FCR (P<0.01) was observed in LA fed animals and the lowest (P<0.01) was recorded in the BD and BDA groups. The improved (P<0.05) digestibility of organic matter, crude fiber, ether extract and nitrogen free extract was observed with 0.4% LA. The faecal total bacterial count and E.coli count were lowered (P<0.01) with LA supplementation, while highest count was observed in control group. Hence, it was concluded that, supplementation of LA at 0.2 to 0.4 % in the diets of LWY piglets showed increased weight gain, feed efficiency and nutrient digestibility by reducing faecal microflora count in LWY piglets.

The present study aimed to develop and standardize RTD dal payasam prepared with coconut milk by replacing bovine milk by cooking dal (moong dal/ split yellow lentils) in coconut milk with added nuts, sugar and shredded coconut. The product was prepared with total solids of 22-23% as per commercial purpose. Three different trials (P1, P2 and P3) with varying quantities of dal (150g, 200g and 250g), jaggery (250g, 150g and 200g) and coconut milk of 200ml (based on preliminary study) was studied. The optimized dal payasam was filled in cans and retort processed at 121.1ºC and overpressure of 1.29 bar with steam pressure of 1 bar. Lethality time (F0) of 16.7 min and Total Process Time of 34.2 to 38.7 min was calculated by predictive thermal process modeling. Sensory evaluation of P1, P2 and P3 concluded that P3 with 250g moong dal, 200g jaggery, 200 ml coconut milk was highly preferred by sensory panelists. The finalized trial was further studied for its physico-chemical properties for 60 days at refrigerated (4±2ºC) and room temperature (25±2ºC). The study concluded that retort processed Ready-to-Drink dal payasam packed in cans was safe to consume upto 60 days of storage.

A six-year-old Siberian husky bitch was presented to Small Animal Gynaecology and Obstetrics Unit, Madras Veterinary College Teaching Hospital, with a history of proestrus bleeding and prolonged breeding failure due to shyness. Based on progesterone value (8 ng/mL, artificial insemination was done. On day 45 post AI, ultrasonographic examination revealed the presence of a viable foetus and lateral abdominal radiography showed the presence of a single foetus. Based on the observations, the owner was made aware of chances of risk of dystocia due to single puppy syndrome and the case was kept under observation. However, the case was presented on day 65 of gestation with signs of inappetence and greenish black vaginal discharge for the past 6 hrs. Based on the Ultrasound examination, Radiography and progesterone concentration, the case was diagnosed as dystocia due to single puppy syndrome. Under local anaesthesia, episiotomy was performed and a viable foetus (650 gm) was delivered. The episiotomy wound was closed in simple interrupted suture pattern using polyamide (1-0). After one week of postoperative care, the bitch had an uneventful recovery.

2024
M. Pradeep
Animal body reacts to all kinds of injuries and stress to keep the homeostasis. Such resistance can be specific or non specific. Non specific innate resistance of the body like cytological and cytokine reactions including fever, leukocytoses etc. are known as acute phase response. In this response, there will be increase or decrease of serum concentration of particular proteins. These proteins are known as acute phase proteins. Measurement of serum concentration of these acute phase proteins are found to be useful in assessment of health status and prediction of diseases of the man and animals. Acute phase proteins like Serum amyloid A, C- reactive proteins, Haptoglobin, alpha 1 acid glycoprotein etc. are found to be more sensitive and specific than the routine diagnostic methods like white blood cell count. Use of acute phase proteins as biomarkers for animal disease diagnosis and health status assessment has got high potential in modern veterinary practice. Usefulness of the acute phase protein analysis in veterinary practice especially in dog, cat, cattle and pig practices is discussed in this review.
