A study was conducted in four flood-prone villages at Krishi Vigyan Kendra, Assam Agricultural University, Dhubri to assess the production performance of Khaki Campbell ducks and the economics of rearing them under NICRA (National Innovations in Climate Resilient Agriculture) project. A total of 10 farmers were selected from Dhubri village on the basis of their experience in duck farming. Two hundred day-old Khaki Campbell ducklings, twenty numbers irrespective of sex per household, were distributed and reared up to 72 weeks. On attaining 30th week of age, the male ducks were sold out. The data including body weight, mortality, age at first egg and egg production were recorded. The average age at first egg was 163.0±3.6 days, and 30th week mean body weight was 1.8±0.1 kg. The mean egg production and mortality rate were 180.8±4.1 and 13% respectively during the study period. It was found from the study that Khaki Campbell duck farming has contributed notably to the livelihood of the rural farmers with benefit-cost ratio of 1.87.

2024
D.C. Roy | R. Gogoi
The present study was undertaken to detect residues of Tetracycline in marketed pork using a High Performance Liquid Chromatography (HPLC) System and a UV-Vis Spectrophotometer. 300 samples of marketed pork were collected for the study. The samples after collection were preserved at -20°C. Analyses of the samples using High Performance Liquid Chromatography with UV-Vis Detector were done as per the method of Oka et al., 1985 while analyses of the same samples using UV-Vis Spectrophotometer were done as per the method of Yongnianian et al, 2010. Recovery ranged from 85-93% (HPLC) and 68-83% (Spectrophotometer). Out of the tested samples, 4 samples were detected to be positive for trace residues of tetracycline using Spectrophotometer while 6 samples were detected for tetracycline residues using HPLC method which were well below the Maximum Residue Limit (MRL) value. The method of HPLC is more sensitive than the Spectrophotometric one. Thus, the HPLC method is useful for monitoring of tetracycline residues in pork.

We estimated the incidence of clinical mastitis (CM) and antimicrobial agent (AMA) usage for its treatment in an organized dairy farm over a period of six months. The incidence of mastitis at different stages of lactation was also quantified. The incidence of mastitis was higher in Sahiwal cows (9.52%) compared to crossbred cows (3.61%). Among different AMA usage, enrofloxacin (22%), ampicilin with cloxacillin (18.57%), gentamicin (18.29) and ceftriaxone (12.57%) drugs were most commonly used against CM cases. Penicillin group and their combinations (29.43%) was found to be the most commonly used AMA for CM followed by fluoroquinolone (22%), aminoglycosides groups (21.43%) and cephalosporins group (16.86%) of drugs. Tetracyclines (9.14%) and chloramphenicol (1.14%) were least choice as evidenced by less frequent usage. From the findings of the study it may be concluded that the incidence of mastitis was high in Sahiwal cows milked with machine milking system and mastitis animals needed an average of five days treatment for clinical cure. Further, â-lactam group of antimicrobial drugs were predominantly used in mastitis treatment, despite entry of new AMA in the market.

A. Sangaran | S. Arunkumar | Lalitha John
Hydatidosis, caused by the larval stage of the dog tapeworm, Echinococcus granulosus is considered to be an important condition in herbivores such as cattle, buffaloes, sheep and goats. Due to its presence in the food animals meant for meat purpose, the disease is considered to be of economic and public health significance owing to the impact it produces on the meat industry by condemnation of the affected organs. Food animals such as sheep, goats get infected by accidental ingestion of contaminated feed and water with the eggs of the tapeworm. Development of the cysts in the intermediate host such as sheep and goats occurs in the lungs, liver and other visceral organs. The disease remains asymptomatic in most cases in spite of the presence of the hydatid cysts for a long period. A study was undertaken to find out the incidence of the hydatid cysts in sheep and goats in the Corporation slaughter house by examination of the carcasses of the slaughtered sheep and goats. By the study, an overall incidence of 6.5% in sheep and 5.8% in goats were observed with the sheep harbouring more number of fertile hydatid cysts which plays a major role in dissemination of infection to dogs.

The genus Capripoxvirus (CaPV) comprises three members namely, sheep pox virus (SPPV), goat pox virus (GTPV) and lumpy skin disease virus (LSDV) affecting sheep, goats and cattle, respectively. Capripoxvirus infections produce similar symptoms in sheep and goats, and the three viruses cannot be distinguished serologically. The Capri pox virus disease is an economically important notifiable disease of cattle, sheep and goats (OIE, 2018). This article reviews about the current scenario of Capri pox disease and the better opportunities for prevention and control of disease. Recent outbreaks of the disease have caused the major economic loss in most of the countries including India.

Follicle like structures with a minimum of 17 mm diameter and persisting for more than 6 days in the absence of corpus luteum is called as follicular cyst. It is the hypothalamo-hypophyseo gonadal axis that governs the reproductive events primarily. Plasma is a medium that reflects the changes in any organ apart from providing nutrients and draining the metabolic wastes. Cows brought for infertility treatment were screened and cows which were diagnosed as follicular cyst randomly allotted in to four groups of eight cows each. Different groups were subjected to different treatment protocols viz, Regular co-synch protocol, modified co-synch protocol, Trans-gluteal follicular cyst evacuation technique and trans-gluteal follicular cyst evacuation technique cum modified co-synch protocol for Group I, II, III and IV, respectively. Blood samples were collected from all the cows of different groups on day 0 (initiation of treatment), 7 and 9 of treatment and were analyzed for biochemical parameters. Cholesterol, triglyceride, total protein, calcium and phosphorus concentration was quantified using an automatic analyser UV-VIS spectrophotometer. There was no significant difference (P > 0.05) noticed between the mean concentration of biochemical parameters of different treatment groups, on days 0 and 7 in serum. The mean concentrations of cholesterol were 116.13±20.28, 59.67±10.50, 70.88±6.57 and 64.00±8.36 mg/dl in Group I, II, III and IV cows, respectively and were significantly (P < 0.05) higher in Group I. The mean concentration of all other biochemical parameters were non-significant (P > 0.05) between all treatment groups, on day 9 in serum. This might be due to steroid bio transformation of cholesterol.

Leptospirosis is a zoonotic disease caused by pathogenic species of Leptospira interrogans. Dogs can act as maintenance host for some serovars and transmit to other animals and humans through direct and/or indirect contact with urine or contaminated water and soil. A study was conducted to identify the presence of Leptospira and assessment of seroprevalence in apparently healthy dogs in Cauvery delta region (Thanjavur, Thiruvarur and Nagapattinam districts) of Tamil Nadu. Serum (n=50) and urine (n=50) samples were collected randomly from 50 dogs with history of non vaccination to leptospirosis. Dark field microscopic (DFM) examination revealed the presence of Leptospira in 12.0 per cent of serum and 24.0 per cent of urine samples. Serological screening was done by microscopic agglutination test (MAT) using a battery of 12 Leptospira serovars (representing the serogroups of Australis, Autumnalis, Ballum, Canicola, Grippotyphosa, Hardjo, Hebdomadis, Icterohaemorrhagiae, Javanica, Pomona, Pyrogenes and Tarassovi), which revealed 56.0 per cent seropositivity to either one or several serovars, which was Icterohaemorrhagiae (46.4 per cent), Grippotyphosa (32.1 per cent), Australis (32.1 per cent), Canicola (25.0 per cent) and Autumnalis (17.9 per cent) with highly significant difference (p<0.05) in seropositivity between serovars. The predominant serovar detected in dogs in this study was Icterohaemorrhagiae followed by Grippotyphosa. It is concluded that presence of leptospirosis in dogs in Cauvery delta regions of Tamil Nadu poses the risk of transmission to animals and humans and dogs can be used as sentinel animals for identification of leptospirosis.
