Assessment of Livestock Production Technologies and Package of Practices through Multivariate Typology: A Case of Maharashtra, India
(Association of Mastitis, 2020-02) Pathade, Santosh S.; Singh, B.P.; Chander, Mahesh; Dubey, D.
The study was carried out in four different agro-climatic zones of Maharashtra. A typology was developed applying multivariate statistical techniques i.e. Cluster analysis (CA) to classify groups of farm households with similar farm characteristics into four homogenous clusters, (i) households possessing small landholding, a larger high yielding dairy stock with small goat flock size (37.5%), (ii) households having small landholding with a small stock of high yielding dairy animal and small goat flock size (39%), (iii) households having large landholding with large high yielding dairy stock and small flock size (13.5%) and (iv) households possessing small landholding with small high yielding dairy stock and large flock size (10%). An assessment in terms of awareness, knowledge and adoption of dairy technologies and goat production practices were carried out across the clusters which was found significantly high within the household of cluster 3 and 4. The overall adoption index was found to be 65.16 per cent across the whole clusters. Multiple regression analysis revealed that total SAU, flock size, occupation, innovative proneness, scientific orientation, awareness of technology and knowledge of technology contribute positively (P<0.01, P<0.05) to the adoption of technology. The coefficient of determination was found (R2 =0.66) across the whole clusters

(Association of Mastitis, 2020-02) Sharma, Vikas; Jhirwal, Arun Kumar; Goswami, Subhash Chander; Choudhary, Vijay Kumar; Singh, Vikramjit; Meena, Budhi Prakash
The present investigation was carried out with the total of 18 Sahiwal cattle of 1st to 4th parity were selected for the study and distributed into three different groups based on their pre calving BCS (before 15 days of expected date of calving) namely G1 (2.50 - 3.00), G2 (3.25 - 3.75) and G3 (4.00 and above) with six animals in each group. The average fortnight milk yield increased up to 60th day and thereafter declined up to 90th day in G1, G2 and G3 group of animals, which was significant (p<0.05) up to 75th day. G3 group animals had highest average fortnightly cumulative Milk yield (Kg) in entire study period. Highest 305 days predicted lactation milk yield (2462.66 Kg /lactation) and average peak yield (16.50 Kg/ animal) was obtained in G3 group animals and the lowest predicted lactation milk yield (1870.68 Kg/lactation). The 305 days predicted lactation milk yield in G2 group animals was 2356.75 Kg /lactation and average peak yield was 14.90 Kg/ animal. The G3 group animals also attained their peak yield in 46 days compared to G2 and G1 group animals with 51 and 54 days, respectively. The persistency of milk production was highest in G2 group animals with 65.63 % followed by G3 and G1 group animals. The studied revealed that BCS had a significant (P<0.05) effect on post-partum estrus and service period in experimental animals

(Association of Mastitis, 2020-02) Gill, Amandeep Kaur; Gursimran, Filia; Leishangthem, Geeta Devi; Narang, Deepti; Singh, Sikh Tejinder; Singh, Charan Kamal
Bovine tuberculosis, a chronic disease of animals is caused by species of Mycobacterium tuberculosis complex (MTC) and it remains a potential threat to animals as well as humans. Differentiation of the species of MTC is required for epidemiological and diagnostic purpose. The present study evaluated the presence of different species of MTC in bovines using gyrB-restriction fragment length polymorphism analysis. In this study, blood and milk samples from 50 milch animals which were positive reactors of comparative intradermal tuberculin test were collected. Screening of MTC was done by IS6110-PCR using primers INS1/INS2 specific for MTC. The positive samples were further identified using gyrB- Restriction fragment length polymorphism analysis. Out of 50 positive reactors to CITT, only 4 (8%) animal were positive for MTC by IS6110-PCR. And gyrB-RFLP analysis using RsaI and SacII showed two positive for M. bovis and two animals for M. tuberculosis. Thus, gyrB-RFLP could be used as an additional tool in differential diagnosis of mycobacterial diseases thereby able to differentiate species of MTC

(Association of Mastitis, 2020-06) Saharan, Vivek; Pathak, A.K.; Sharma, Neelesh; Sharma, R.K.; Kumar, Himalaya
Present study was conducted in 240 day-old broiler chicks to assess the effect of condensed tannins (CT) containing guava leaf meal (GLM) supplemented diet on nutrient composition, litter metabolites viz. pH, moisture and ammonia concentration) and microbial counts after completion of feeding trial of 42 days. Chicks were randomly allocated into 4 dietary treatments, with 4 replicates of 15 chicks in each pen in a completely randomized block design (CRD). Chicks were fed basal diets supplemented with GLM @ 1.5, 2.5 and 3.5 percent, in T1, T2 and T3 groups, respectively, while, T0 group fed only basal diet. Litter materials of chicks showed good nutrient profiles and properly sterilized litter material act as alternative feed ingredient for ruminants feed. Supplementation of GLM in the diets of chicks significantly (P<0.05) reduced moisture, pH, NH3 concentration, harmful Eschericia coli and Clostridia spp. counts in the litter materials and reduced environmental pollution. The litter material of GLM supplemented (T1, T2 and T3) chicken showed significantly higher (P<0.05) CP contents as compared to un-supplemented control. It can be concluded that properly sterilized litter material of GLM supplemented chicks act as cheaper alternative feedstuffs for ruminant’s ration and reduce environmental pollution by lowering NH3 concentration, harmful E. coli and Clostridia counts in broiler litter material

(Association of Mastitis, 2020-06) Gupta, Rohit; Sahoo, Saroj Kumar; Kaur, Simarjeet; Dash, Shakti Kant; Malhotra, Puneet; Bansal, Baljinder Kumar
The present study was carried out using first lactation monthly test-day milk yield records of 466 crossbred (HF × Sahiwal) cattle calved from 2000 to 2018 sired by 89 bulls maintained at Directorate of Livestock Farms, GADVASU, Ludhiana. Mixed model analysis was carried out by least-squares maximum likelihood programme to study the effects of non-genetic factors on first full lactation milk yield (FFLMY), first lactation 305-day milk yield (FL305MY) and monthly test-day (TD) milk yield records of crossbred cattle. The least squares means of different monthly TD milk yields (1st to 11th) were 12.05 ± 0.42, 15.65 ± 0.42, 15.38 ± 0.44, 14.44 ± 0.43, 13.79 ± 0.41, 12.88 ± 0.40, 12.27 ± 0.42, 11.83 ± 0.37, 10.85 ± 0.42, 10.64 ± 0.45 and 10.28 ± 0.50 kg, respectively. For FFLMY and FL305MY the means were 4979.60±184.45 and 3818.17±103.26 kg. The effects of different AFC groups were non-significant on TDs and FL305MYs, whereas it was significant (p≤0.01) for FFLMY. The season was significant (p≤0.01) for all the monthly TDs whereas it was non-significant for FFLMY and FL305MY. The sire was significant (p≤0.01) for most of the TDs and FL305MYs except the later TDs (9th, 10th and 11th TD) and FFLMYs. The present investigation revealed the importance of non-genetic factors in performance evaluation of crossbred cattle based on monthly test-day milk yield, FL305MY and FFLMY records

(Association of Mastitis, 2020-06) Zargar, M.A.; Pathak, A.K.; Sharma, R.K.; Daing, M.I.
Present study was conducted in 120 day-old unsexed broiler chicks. They were randomly distributed into 4 dietary treatments (T1, T2, T3 and T4) supplemented with leaf meal mixture (LMM) of Eugenia jambolana and Psidium guajava@ 0, 2.5, 5.0 and 7.5 % of diet, respectively of 30 birds per treatment, each having 3 replicates (10 chicks per replicate) in a complete randomized block design (CRD). Significantly (P<0.05) higher mean body weight was observed in T1 as compared to T2, T3 and T4 groups. Carcass yields viz. live weight, de-feathered weight, slaughtered weight and eviscerated weights (in gram and % LWt.) were statistically non significant (P>0.05) with and without LMM supplemented diets. However, weights of spleen and liver were significantly (P<0.000, P<0.026) higher in LMM supplemented groups as compared to un-supplemented control (T1). Dietary supplementation significantly reduced abdominal fat content in T4 compared to T1, whereas, T2 and T3 have an intermediate values between T1 and T4 and increased the net profit, it ranged from ` 30.41 to 34.24 per bird

(Association of Mastitis, 2020-06) Lachungpa, Chopel G.; Chandrasekaran, D.; Thilagar, M.B.; Kumar, T.M.A. Senthil
Immune-mediated hemolytic anemia (IMHA) is the most common autoimmune disease in dogs. This study was conducted to evaluate prednisolone and azathioprine therapeutic protocols for the management of idiopathic IMHA in dogs. The anaemic dogs brought with clinical signs such as pale or icteric mucous membranes were screened for IMHA by saline agglutination and spherocyte count and confirmed by flow cytometry. The positive cases were further subjected to haematology, biochemistry, coagulation profile, MAT and polymerase chain reaction (PCR) for the diagnosis of underlying secondary causes like Babesia spp, Ehrlichia canis and Leptospira spp (secondary IMHA). Thirty two cases were positive for IMHA, out of which thirteen cases were primary (Idiopathic) IMHA (17.3 %) and remaining nineteen cases were secondary IMHA (82.7 %) due to underlying causes such as Babesia gibsoni (13), Ehrlichia canis (3) and Leptospira spp. (3) respectively. Immunosuppressive therapy with prednisolone and prednisolone in combination with azathioprine and specific therapy of etiological agent with supportive therapy was used. Significant increase in Hb, PCV, RBC and thrombocyte count, significant decrease in leucocyte, neutrophil, monocyte and total protein and significant increase in ALT activity was recorded after therapy. Prednisolone was found to be effective in the management of canine IMHA than prednisolone combined with azathioprine

(Association of Mastitis, 2020-06) Anandh, M Anna
Pickle from native desi chicken meat was prepared and stored at room temperature (32±5ºC) in polyethylene teraphthalate (PET) bottles. The samples were evaluated for physico-chemical parameters, microbial quality and sensory attributes at regular intervals of 0, 5, 15, 30, 45,60, 75 and 90 days of storage. Non significantly increase in pH values were observed with increasing storage period and value remained below 5.0 up to 60 days of storage period. Non significantly increase in titrable acidity (% acetic acid) and free fatty acids (as % oleic acid) values were observed with increasing storage period. However, significantly decreased in moisture (%) values were observed with increasing storage period. A significant (P<0.05) and progressive increase in Thiobarbituric Acid (TBA) values (mg malonaldehyde / kg) were observed with increasing storage period and increase in TBA values between 0 and 60 days of storage did not turn out to be statistically significant. Microbiological counts were nonsignificantly increased between day 0 to 60, thereafter significantly (P<0.05) increased with the advancement of storage period and throughout the storage period, all microbial counts were within the acceptable limits. Sensory evaluation scores indicate that native desi chicken meat was very acceptable up to 60 days of storage and thereafter native desi chicken meat pickle was moderately acceptable between 60 to 90 days of storage at room temperature (32±5°C)

(Association of Mastitis, 2020-06) Sawai, Dhiraj; Jadhao, Gajanan; Pawar, Kalpana; Dhok, Atul; Sarode, Roshan
The experiment was conducted to study the effect of dietary supplementation of critical amino acids and multi-enzyme with reduced levels of energy and protein diet on carcass and blood biochemical performance in broiler chicken. Three hundred broiler chicks were allotted to five dietary treatments of three replications and 20 birds in each replication. The control (T0) were fed with standard diet, T1 (5% low CP and energy than standard with balancing of lysine and methionine), T2 (T1 + Multi-enzyme), T3 (10% low CP and energy than standard with balancing of lysine and methionine), T4 (T3 + Multi-enzyme).The dressing percentage and edible meat percentage were significantly more in T2 group. The breast meat percentage of the control group was comparable with T2 group. The result showed that the significantly higher (P<0.05) gizzard weights in groups receiving enzyme combination supplementation as compared to control group (T0) irrespective of the energy-protein levels. The mean value of total protein, albumin, globulin and blood urea nitrogen of all the experimental birds were found to be statistically similar with that of the control group. The treatment group T2 found to be effective and economical

(Association of Mastitis, 2020-06) Chauhan, S.S.; Sharma, R.K.; Singh, B.; Shukla, S.K.; Palod, J.; Singh, M.K.
The present study was evaluated the effect of dietary inclusion of various feed supplements and their combination on the performance index, glucose and serum cholesterol for 6 weeks. Day-old broiler chicks (n=252) were randomly assigned to seven treatment groups, each with 3 replicates. The first treatment was designated as control (T0) in which no supplement was added to the feed, while in treatments T1; organic mineral mixture (Organomin forte), T2; organic mineral mixture (Vannamin), T3; probiotics (Microguard), T4; enzyme (Brozyme -XPR) and probiotics, T5; emulsifier (Lipigon) were provided through feed. In the T6 group, 3 percent less energy was given through feed. The weight of vital organs viz. heart, liver, gizzard, and spleen were significantly (P<0.05) increased by the feed supplements of which were in the normal range. The gut morphology was also favorably altered due to feed supplementations. This indicates that the organic mineral mixtures, probiotics, enzymes and emulsifiers, and their combinations can be used as a growth promoter in broiler diets and can improve gut health. These products show promising effects as alternatives for antibiotics as pressure to eliminate growth-promoting antibiotic use increases

(Association of Mastitis, 2020-06) Soman, Swathi; Sharma, R.K.; Sharma, Varsha; Gautam, Vidhi; Shrman, K.; Sawarkar, Alka; Kewat, Rituraj; Kumar, Manish
Drug resistance in bacteria is becoming an alarming problem in recent years. Post-antibiotic era is not so far. The need for novel antibiotics, chemotherapeutic agents and agrochemicals are utmost. Endophytes are microorganisms that reside in the tissues of living plants which are relatively unstudied and are potential sources of novel natural products for exploitation in medicine, agriculture and industry. The endophytes of medicinal plants participate in biochemical pathways and produce novel bioactive compounds. The aim of the study was to isolate, identify and to assess antibacterial activity of endophytic bacteria from leaves of Acacia catechu. 18 endophytic bacteria had been isolated and identified by sequencing 16S rRNA gene. The isolated endophytic bacteria were identified as Bacillus humi. Considerable in vitro antibacterial activities against a panel of human pathogenic microorganisms (Staphylococcus aureus, Streptococcus pyogenes, Bacillus cereus, Klebsiella pneumoniae, Salmonella Typhimurium and Escherichia coli) were recorded. Among 18 isolates, 15 isolates had shown inhibitory activity against Staphylococcus aureus and Salmonella Typhimurium and 10 isolates had shown inhibitory activity against Klebsiella pneumoniae
Conservation Priorities for Indian Goat Breeds Based on Microsatellite and Analytical Data
(Association of Mastitis, 2020-06) Sah, Rajkumar; Dixit, S.P.
The demographic and microsatellite data on 25 markers along with non genetic information such as distribution, adaptation and utility pertaining to 24 Indian goat breeds were used to assess their conservation priorities. The effective population size (Ne) of Gohilwadi, Jharkhand Black and Sangamneri was greater than 200 and that of Black Bengal, Kutchi, Mehsana, Sirohi, Malabari and Zalawadi ranged from 100 to 200 but it was below 100 for rest (60%) of the breeds with Ganjam having the least value of 17.5 based on microsatellite data. All goat breeds whose effective population size is greater than 100 based on markers did have population size between 0.1 and 0.2 million except in few cases. The Ne based on microsatellite and demographic data revealed almost same order of ranking of goat populations. It was also revealed that Attappady and Kutchi were at highest risk of extinction probability (0.63) and more than half of the Indian goat breeds were having less than 50% extinction probability. Therefore, Attappady and Kutchi should be given top priority for conservation

(Association of Mastitis, 2020-06) E., Venkatesakumar; G., Vijayakumar; G.A., Balasubramaniam; J., Johnson Rajeswar
Seventy two cattle with bacterial pneumonia and twelve healthy cattle were studied in detail for haemato-biochemical examination, radiography and tracheobronchoscopy. Haematobiochemical examination revealed leukocytosis with neutrophilia. Radiographic examination showed increased pulmonary infiltration. Tracheobronchoscopic examination of affected animals revealed inflammation, haemorrhage, mucus to mucopurulent exudates in nasal cavity, trachea, bronchi and bronchioles. Bronchoalveolar lavage (BAL) collected through endoscope was subjected to cytology and cultural examination. Cytology of the affected animals showed increased total cell counts and predominant neutrophils. Pasteurella multocida, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli were isolated from BAL and confirmed with PCR studies
Metabolic Profiling of Normal and Lame Karan Fries Cows and its Association with Lameness during Transition Period
(Association of Mastitis, 2020-06) v, Pragya; Lathwal, S.S.; Jadoun, Y.S.; Gupta, Rohit
In high yielding dairy cows, one of the major cause of lameness during transition period is the altered nutritional status of pregnant animal. Concentrations of essential nutrients get varied and often decrease around calving due to physiological factors and thus extra-supplementation is recommended in these animals. Blood measures are frequently used in assessment of the vital nutrients for predicting the risk of lameness during this period. The objective of this study was to investigate the nutritional status of healthy and lame Karan Fries (KF) cows and their association with lameness score during transition period. For this fifteen high-yielding crossbreed (KF) healthy cows and fifteen high yielding crossbreed (KF) lame cows were randomly selected from the Livestock Research Centre (LRC) of National Diary Research Institute, Karnal for pooled blood sample collection. Samples were collected 60d, 15d pre-partum, on the day of calving, and 60d, 15d post-partum. The results revealed that the mean plasma biotin, zinc (below critical level) and calcium (within range) levels were significantly lower (P<0.05) in lame KF cows while β-hydroxybutyrate (BHBA) concentrations was significantly higher, however no significant difference in plasma copper, glucose and non-esterified fatty acids (NEFA) concentrations was found in lame cows as compared to normal KF cows during this period. There was also significant (P<0.05) variation of blood biochemical profiles (glucose, NEFA and BHBA) and plasma biotin concentration among different lameness scores (1-5) whereas no relation of mineral profiles (calcium, zinc and copper) was seen with lameness score
