Shakti Kant Dash Ashok Kumar Gupta Avtar Singh A. K. Chakravarty Manvendra Singh

Present investigation comprehends the study of the effect of genetic and non-genetic factors and estimation of genetic parameters of Karan Fries cattle with respect to production and reproduction traits across all lactations. Data consisted of a total of 5878 lactation records on 1988 cows over a period of 32 years (1981 to 2012), maintained at ICAR-NDRI, Karnal. Overall least-squares means for CFS(days), SP(days), LL(days), CI(days), 305MY(kg), TMY(kg), MY/LL(kg/days), MY/CI(kg/days) and DPR were found to be 78.21±1.59, 115.46±2.14, 326.57±2.60, 403.91±2.54, 3634.78 ± 30.91, 3976.77 ± 41.03, 12.19 ± 0.08, 10.28 ± 0.08 and 0.37 ± 0.80, respectively. Both production and fertility traits were significantly affected by different factors viz. season of calving, period of calving, parity and genetic group. LSANOVA heritability estimates of SP, CI, LL, CFS, DPR, 305MY, TMY, MY/LL, MY/CI were 0.18±0.08, 0.15±0.07, 0.11±0.05, 0.10±0.09, 0.07±0.07, 0.39±0.09, 0.26±0.07, 0.35±0.08 and 0.42±0.10, respectively. Heritability estimates indicated that fertility traits were less affected by additive gene action. Genetic correlation estimates indicated unfavourable positive correlation between fertility and production traits.

Research Square (Research Square) (2021)

Aadish Balouria Sidhartha Deshmukh Harmanjit Singh Banga M.M. Chawak Shakti Kant Dash

Abstract Introduction Avibacterium paragallinarum (Av.paragallinarum) is the causative agent of infectious coryza (IC) in chicken, an economically devastating disease of poultry industry. Despite the availability of effective vaccines against IC, the infection is rampant in unorganized poultry sector. Moreover, reports of wider host susceptibility in poultry farms and under field conditions are also emerging. Av.paragallinarum affects the upper respiratory tract of birds and has a predilection for the nasal turbinates. However, no study has systematically evaluated the early pathological changes and mucosal immune responses during Av. paragallinarum infection in the nasal turbinates of chicken. Furthermore, the use of Japanese quail as an alternate experimental animal model than chicken in IC remain unexplored. Here, we examined clinical signs, gross and histopathological changes at the nasal turbinates following experimental Av. paragallinarum infection in chicken and Japanese quail. MethodsWe developed a comprehensive scoring system for recording gross and histopathologic lesions during infection. ResultsOur data show that chicken have a higher susceptibility to Av.paragallinarum infection than the Japanese quail . Japanese quail had significantly lower gross as well as histopathology score in nasal turbinates as compared to infected chicken. Importantly, chicken at an early age i.e. 2.5 weeks were able to induce mucosal immune responses against Av. paragallinarum infection. ConclusionOur findings suggest that there are demonstrable differences in the disease pathology and host immune response to Av. paragallinarum infection in chicken and Japanese quail and warrant further investigation for the use of Japanese quail as an animal model for IC.

Culling pattern of Karan Fries (crossbred) males in an organised herd

Indian Journal of Animal Research (2016)

Achun Panmei Ashok Kumar Gupta Pushp Raj Shivahre Mukesh Bhakat Shakti Kant Dash

Information on culling pattern of animals helps in developing effective breeding plans for genetic improvement of the herd. Data on 292 reserved KF males out of 1740 male calves born, spread over a period of sixteen years from 1997 to 2012, were collected based on pedigree performance. The data were analysed using descriptive statistics considering the period of birth, season of birth, genetic group and age group. Study revealed increase in culling percentage with advancement in age. Culling in KF males for the different periods (1997-2000, P-1; 2001-2004, P-2; 2005-2008, P-3 and 2009-2012, P-4) were 75.93, 92.16, 64.44 and 28.26 percent, respectively. Maximum culling was observed in males born in summer season (76.12%) which could be due to inclement weather conditions exposure in young age and insufficient quality green leguminous fodder in subsequent months. Generally, upto the age of 3 years, culling in KF males were maximum in interbred and minimum in F1 but with advancing age, culling rate was found higher in F1 genetic group KF males where reproductive problems were the main causes. High culling rate in less than 1.5 yrs age groups was observed due to poor growth (3.42%) while in adult bulls of above 1.5yrs of age, main reasons of culling was surplus (33.22%) followed by poor semen quality (10.27%), poor libido (7.53%), and poor semen freezability (4.45%). It can be concluded that culling pattern study can help in formulation of better management strategy to reduce the problems associated with culling and better economic return for the farm.

Prediction of Market Weight in Caribro-Dhanraja Broilers with Different Plumage Colour Using Growth Traits

International Journal of Current Microbiology and Applied Sciences (2018)

T. K. Patbandha D. D. Garg D.G. Vaghamashi S. Marandi K. Ravikala

Present study predicted 6th week body weight of Caribro-Dhanraja broilers (n=75) with different plumage colour through backward elimination regression from 2nd week growth traits (weight, weight gain, chick length, weight: length2, shank length, toe length, breast length, breast girth, thigh length and wing length). Day old chicks were grouped into yellow, black and stripped colour groups based on plumage colour (25 chicks in each group) and traits were measured biweekly upto 6th week. Plumage colour significantly influenced shank, toe and thigh length, and breast girth at 2nd week; whereas, wing length at 4th week (Pï'£0.05). In yellow plumage group, weight, daily gain, weight: length2, shank, breast and thigh length at 2nd week were positively associated with 6th week body weight (Pï'£0.05). In black plumage group, weight, daily gain and weight: length2 of 2nd week were positively association with 6th week body weight, but thigh length was negatively associated (Pï'£0.05). Weight, daily gain and weight: length2 at 2nd week were positively associated with 6th week body weight in stripped plumage group (Pï'£0.05). Backward elimination regression model for prediction of 6th week body weight from 2nd week variables revealed higher R2 value (59.6%) in black plumage (predictor variables were weight, breast girth and thigh length). However, R2 value was 36% for stripped colour (predictor variables were weight and breast girth), 25.3% for yellow plumage (predictor variable was wing length) and 41% for pooled data (predictor variables were growth and breast girth). The results indicated lower accuracy for prediction of 6th week body weight based on variables from 2nd week.

Multiple linear correlation and prediction of lifetime performance on the basis of first lactation fertility and production traits in Karan Fries (Holstein Friesian crossbred) cattle

Indian Journal of Dairy Science (2015)

Shakti Kant Dash Ashok Kumar Gupta Avtar Singh T. K. Mohanty Ved Prakash

Higher productions along with superior fertility are the functions of greater stayability of dairy cattle in the herd. Present investigation was undertaken to evaluate lifetime traits and their prediction on the basis of first lactation traits in Karan Fries cows maintained at National Dairy Research Institute. Data of 5878 lactation records of 1988 adult cows pertaining to the period between 1978 to 2012, were collected for analysis. The phenotypic and genetic correlations of first lactation with lifetime traits were estimated and lifetime performance was predicted using backward elimination multiple linear regression models. Cumulative milk yield (CMY) analysis indicated that the Karan Fries cows achieved around 85% of their lifetime production by 4 th lactation. Phenotypic and genetic correlations of lifetime production traits were positive with first lactation production traits, whereas the association was negative with first lactation fertility traits. The coefficient of variation and mallows Cp criterion estimates of better fit models were lower and ranged between 12 to 18% and 2.51 to 6.00, respectively. Results indicated that the first lactation traits used for the prediction, best explained the variation in traits such as Lifetime yield upto two lactations (51.00%) and breeding efficiency (51.43%), on the basis of coefficient of determination (R 2 )estimates. Regression models for predicting lifetime yield upto three lactations, milk yield per day of productive life and lifetime daughter pregnancy rate had moderate coefficient of determination estimates.

Association of polymorphic variant of exons 6 and 11 of lactoferrin gene with mastitis in Murrah buffalo

The Indian Journal of Animal Sciences (2020)

Krishanender Dinesh Archana Verma I.D. Gupta Shakti Kant Dash

Lactoferrin is one of the important candidate genes for mastitis resistance in dairy animals. The gene is located on Bos taurus autosome (BTA) 22 and consists of 17 exons spanning over 34.5 kb of genomic DNA. The present study was undertaken to identify allelic variant in exons 6 and 11 of lactoferrin gene and to analyze association with incidence of clinical mastitis in Murrah buffalo. The amplification of exons 6 and 11 of lactoferrin gene yielded 301 and 131 bp amplicon size. Comparison of nucleotide sequence of exonic region of lactoferrin gene with Bos taurus (NCBI accession number AC_000179.1) revealed 6 mutations; among them 3 were in coding DNA sequence and remaining 3 were in flanking intronic region. All these mutations were found in exon 6 and synonymous in nature without affecting the sequence of amino acid. PCR-restriction fragment length polymorphism (RFLP) analysis of 301 bp amplicon using FokI restriction enzyme exhibited polymorphic pattern with two genotypes (AA and AB) with respective frequency of 0.625 and 0.375. The frequencies of two alleles, A and B were estimated as 0.81 and 0.19 respectively. RE Hpy188I and HinfI used for digestion of exon 11 had exhibited monomorphic pattern. The chi-square (χ2) analysis revealed significant association between incidence of clinical mastitis and genetic variant of exon 6 and animals with AA genotype were found to be less susceptible to mastitis. The findings indicate potential scope for incorporation of lactoferrin gene in selection and breeding of Murrah buffaloes for improved genetic resistance to mastitis.

The Indian Journal of Animal Sciences (2021)

Tavsief Ahmad Ankit Magotra A. Gupta Shakti Kant Dash Mohsin Ayoub Mir

The current study was undertaken with the objective of sire evaluation as well as studying the effect of genetic and non-genetic factors on growth performance in males of Tharparkar and Karan Fries Cattle. Data on body weights of Tharparkar and Karan Fries males born during the period 1994-2012 at ICAR-NDRI, Karnal, were utilized. The overall least squares means of birth weight and weights at one-month interval up to 12 months of age were 26.92±0.24, 35.55±0.22, 45.04±0.28, 57.56±0.40, 70.02±0.51, 82.62±0.66, 95.18±0.80, 105.11±1.55, 108.19±1.15, 114.20±1.15, 120.11±1.09, 130.35±1.11 and 136.91±4.13 kg respectively, in KF males. In TP males, least square means for birth and one-month were 21.34±0.77 and 25.63±0.67 kg, respectively. Effect of month and period of birth was highly significant on all traits except 1 month and 12-months for the former effect. The effects of genetic group and parity were mostly significant on body weights in KF males. Regression on birth weight was highly significant for all the weight traits. Effect of sire and birth-month was highly significant on all traits except one-month weight in KF. In Tharparkar, effect of season was highly significant on birth weight. Growth curves were linear, and deviations of average body weekly weight showed more divergence with increasing age. Growth rates from birth to three-months age in KF and TP males were 320 g/day and 226 g/day. Effect of non-genetic factors indicated the need of further improvement in feeding and management practices for augmenting growth, i.e. body weights especially in calves born to primiparous dams.

Analysis of genetic trend in fertility and production traits of Holstein Friesian crossbred cattle using BLUP estimation of breeding values

Indian Journal of Dairy Science (2015)

Shakti Kant Dash Ashok Kumar Gupta Avtar Singh A. K. Chakravarty Jamuna Valsalan

Selection to improve dairy cattle production leads to a decline in fertility performance due to unfavourable association between the traits. Analysis was carried out to study the genetic trend in the fertility traits of Karan Fries (Holstein Friesian crossbred) cattle due to selection favouring production traits. Data spread over a period of 34 years (1978 to 2012) were utilized to study the traits viz . first lactation 305 day milk yield (F305MY), first service period (FSP) and first lactation daughter pregnancy rate (FDPR). Heritability estimates were obtained using average information restricted maximum likelihood (AIREML) were 0.31±0.10, 0.12±0.06 and 0.02±0.05 for F305MY FSP, and FDPR, respectively. Significant phenotypic trend estimates obtained for F305MY, FSP and FDPR were 18.71±8.37 kg/year, 1.14±0.51 days and -0.0061±0.0018, respectively. Unfavourable genetic trend estimates of -0.0012±0.0004 was obtained for FDPR. The results indicated that continuous selection for production performance had negatively impacted fertility which was evident from a declining trend in fertility performance of Karan Fries cattle in contrast to an increasing trend in production performance.

Effect of Supplementation of Concentrate on Growth Performance of Grazing Ganjam Goats in its Native Tract

Animal Nutrition and Feed Technology (2012)

Usha Mohan Das R.K. Swain Snehasish Mishra P.K. Dehuri Shakti Kant Dash

In order to study the effect of supplementation of concentrates, 40 male kids were randomly divided into four equal groups and kept either on normal browsing (as per farmer’s practice; (G1) alone or with additional supplementation of concentrate mixture at 50 (G2) 100 (G3) and 150 (G4) g per day per kid. During the experimental period of 120 days, BW of kids was recorded fortnightly. Blood was collected at monthly interval. A digestibility trial was conducted at the end of experimental feeding period employing indicator method. Further, 27 top feed resources were identified in order to study the availability of top fodders to grazing Ganjam goats in the native tract. The average CP, EE, CF, NFE, total ash and Ca were observed to be 16.15±0.89, 5.59±0.34, 20.98±0.72, 48.68±1.25, 8.57±0.47 and 1.94±0.13 percent on DM basis, respectively. The ADG of the kids was 31.32±0.47, 41.45±0.38, 54.02±0.19 and 62.84±0.37 g in G1, G2, G3 and G4 respectively, with significant difference (P≤0.05) among all the groups. Blood glucose and cholesterol levels were significantly (P≤0.05) higher in G3 and G4 compared to G1 and G2; however, no differences (P≥0.05) were observed in serum levels of total protein, albumin, urea and calcium. The digestibility of DM and other nutrients were significantly (P≤0.05) higher in G4 compared to G1. It is concluded that, provision of 150g concentrate mixture significantly improved growth performance of Ganjam goats attributable to a more efficient utilization of the native pasture.
