ABSTRACT

The North Eastern (NE) India is renowned for its preference for animal-based food. This region is known for its traditional meat products. However, the popularity of these products remains confined to the specific community/location. The knowledge on the traditional preparation methods is generally passed across generations through practice and word of mouth. The traditional style of preparation and the specific ingredients added to each product makes them unique. In this review, an attempt has been made to identify the initiatives, opportunities, and market potential for commercialization of the traditional meat products. These unique features and properties of the traditional meat products have been highlighted. The commercialization of these products will enhance entrepreneurship development and ensure quality ethnic products to the consumer in the NE hill region of India.

ABSTRACT

Aim: Mortality in a broiler chicken farm was investigated for identifying the cause of mortality.

Materials and Methods: A broiler farm with a population of 16000 succumbed to a disease outbreak. Clinical signs, vaccination history and mortality, were recorded. Necropsy examination and microscopic examination were carried out along with toxicological and molecular studies.

Results: The clinical signs in the affected broiler birds were of non-specific nature with a total mortality of 26.39%. Postmortem examination and microscopical findings revealed hepatitis with basophilic intranuclear inclusion, splenitis, myocarditis, and nephritis. Glomerulonephritis was the prominent renal pathology recorded in this study. Polymerase chain reaction test confirmed the presence of fowl adenovirus (FAdV) genome in the target organs, and toxicological examination by thin-layer chromatography revealed the presence of a toxic level of citrinin in the feed samples.

Conclusion: Based on various diagnostic investigations, the mortality in the flock was attributed to inclusion body hepatitis (IBH) complicated with citrinin mycotoxicosis. Thus, apart from liver pathology which occurs in a classical IBH cases, glomerulonephritis too occurs which are also a prominent finding which pathologists often miss. Thus, kidneys should also be examined histologically to assess the microscopic tissue alterations in poultry suspected for IBH along with a mycotoxicological analysis of feed. This will definitely throw light on the synergistic pathology elicited and exhibited by FAdV and mycotoxins in the poultry.

ABSTRACT

Aim: The objective of the study was to detect Shiga toxin-producing Escherichia coli (STEC) and develop a quantitative polymerase chain reaction (qPCR) assay to quantify the bacterial DNA present in different food matrices.

Materials and Methods: A total of 758 samples were collected during a period from January 2015 to December 2016 from Kozhikode, Thrissur, and Alappuzha districts of Kerala. The samples consisted of raw milk (135), pasteurized milk (100), beef (132), buffalo meat (130), chevon (104), beef kheema (115), and beef sausage (42). All the samples collected were subjected to isolation and identification of STEC by conventional culture technique. Confirmation of virulence genes was carried out using PCR. For the quantification of STEC in different food matrices, a qPCR was standardized against stx1 gene of STEC by the construction of standard curve using SYBR green chemistry.

Results: The overall occurrence of STEC in raw milk (n=135), beef (n=132), buffalo meat (n=130), chevon (n=104), and beef kheema (n=115) samples collected from Kozhikode, Thrissur, and Alappuzha districts of Kerala was 19.26%, 41.6%, 16.92%, 28.85%, and 41.74%, respectively. PCR revealed the presence of stx1 and stx2 genes in 88.46 and 83.64 and 30.77 and 40.00% of STEC isolates from raw milk and beef samples, respectively, while 100% of the STEC isolates from buffalo beef and beef kheema samples carried stx1 gene. Real-time qPCR assay was used to quantify the bacterial cells present in different food matrices. The standard curve was developed, and the slopes, intercept, and R2 of linear regression curves were -3.10, 34.24, and 0.99, respectively.

Conclusion: The considerably high occurrence of STEC in the study confirms the importance of foods of animal origin as a vehicle of infection to humans. In the present study, on comparing the overall occurrence of STEC, the highest percentage of occurrence was reported in beef kheema samples. The study shows the need for rigid food safety measures to combat the potential pathogenic effects of harmful bacteria throughout the production chain from production to consumption.

ABSTRACT

Aim: In the recent past, few studies have been carried out about sea buckthorn (SBT) and giloe in chicken as a part of the quest for suitable alternatives to antibiotics. However, studies in turkeys are lacking. Hence, the present study was conducted to evaluate the effects of SBT and giloe leaf meal by dietary feed supplementation in turkey poults.

Materials and Methods: A total of 1-day-old turkey poults (n=84) of small white variety were distributed into four dietary treatments having three replicates each with seven birds. The study was conducted in turkey poults during 0-8 weeks of age. During the experiment, the poults were fed basal ration (28% crude protein [CP], 2800 Kcal/kg ME) T1, T2-basal ration was supplemented with SBT leaf meal powder at 0.5%, T3-basal ration was supplemented with giloe leaf meal powder at 0.5%, and T4-basal ration was fed along with supplementation of both SBT at 0.5% and giloe leaf meal powder at 0.5%.

Results: T2 turkey poults had a significantly higher (p<0.01) body weight gain than T3 and T4 at 7th week of age. Weekly body weight gain was significantly higher (p<0.05) in T2 than T3 during 5th-8th week and 0-8th week of the growth phase. Feed conversion ratio (FCR) was significantly better (p<0.01) in T2 than other treatment groups during 4th-8th week phase of growth (2.09 vs. 2.36, 2.29 and 2.31). Further, FCR was significantly better (p<0.01) in T2 group as compared to other treatment groups during 0-8th week of growth phase (1.95 vs. 2.21, 2.21 and 2.12). Plasma uric acid was found significantly increased (p<0.05) in T1 than T3 and T4, and alkaline phosphatase value was significantly higher (p<0.05) in T1 and T3 than T2. Zinc content of breast (pectoralis major) muscles was significantly higher (p<0.05) in T2 and T4 as compared to T1, while ether extract (EE) in thigh (ilio tibialis) muscles was significantly higher (p<0.05) in T2 as compared to the other treatment groups.

Conclusion: It may be concluded that supplementation of SBT leaf meal at 0.5% may improve production performance of turkey poults. Supplementation of 0.5% SBT leaf meal may result in higher levels of zinc and EE in the breast and thigh cuts of turkey poults.

ABSTRACT

Aim: The aim of the present study was to compare the body weight (BW) gain and physiological parameters such as temperature, respiratory rate (RR), and heart rate (HR) of Angora rabbit reared in different housing systems.

Materials and Methods: A total of 30 angora rabbits (age 4-6 months), weight 1.5 kg in average were divided into three groups, i.e., (outdoor control [OC], indoor in cages [IC], and indoor open [IO]). All rabbits were reared for 10 weeks. Feed and water were given ad libitum. BW gain and physiological parameters such as temperature, RR, and HR were recorded.

Results: All parameters showed some degree of variations. The BW differed significantly (p<0.05). The mean BW in kilogram (kg) of OC group was 1.59±0.03 obtained during the experimental period, while the BW of IC group shows a decrease of 1.43±0.05 and IO group it was 1.49±0.06 kg. The body temperature (BT) of the control group was 38.83±1.07°C, but IC and IO groups show increased in BT (39.10±0.78°C) and (39.33±1.24°C), indicated no significant difference among the groups (p=0.05). The RR in breaths/min of OC group recorded was 40.3±5.20, but the RR recorded for IC and IO groups was 41.2±7.29 and 39.3±6.30 breaths/min, respectively, showed less variation. The HR obtained in beat/min of OC group was 136.9±15.22, IC group (139.1±16.42) and IO group were (139.6±19.90 beat/min) showed less substantial variation.

Conclusion: The present study clearly indicates that housing rabbits in cages and stress condition is a cause of poor welfare due to movement constraint, it will affect the body biotic parameters such as normal temperature, respiration as well as it can reduce the growth performance of animals significantly but housing system may not affect HR.

ABSTRACT

One Health is an emerging global key concept integrating human and animal health through international research and policy. The complex relationships between the human and animal have resulted in a human-animal-environment interface since prehistorical times. The people, animals, plants, and the environment are so intrinsically linked that prevention of risks and the mitigation of effects of crises that originate at the interface between humans, animals, and their environments can only improve health and wellbeing. The “One Health” approach has been successfully implemented in numerous projects around the world. The containment of pandemic threats such as avian influenza and severe acute respiratory syndrome within months of outbreak are few examples of successful applications of the One Health paradigm. The paper begins with a brief overview of the human-animal interface and continues with the socio-economic and public health impact caused by various zoonotic diseases such as Middle East respiratory syndrome, Influenza, and Ebola virus. This is followed by the role of “One Health” to deal the global problem by the global solution. It emphasizes the interdisciplinary collaboration, training for health professionals and institutional support to minimize global health threats due to infectious diseases. The broad definition of the concept is supposed to lead multiple interpretations that impede the effective implementation of One Health approach within veterinary profession, within the medical profession, by wildlife specialists and by environmentalists, while on the other side, it gives a value of interdisciplinary collaboration for reducing threats in human-animal-environment interface.
