    Estimation of Repeatability for Certain Reproductive Trait in Various Grade of Jersey × Red Sindhi Crosses
    (The Association of Mastitis, 2024-10) Singh, R.; Singh, R.P.; Neeraj; Prabhakar, P.
    Estimation of genetic parameters is important to determine the selection criterion and future breeding strategies. Jersey × Red Sindhi crosses are milk-purpose breeds of cattle and are popular among farmers for their high milk yield and efficient reproduction. The term “repeatability” refers to an animal’s likelihood of performing similarly to or better than the herd average in her next lactation than she did in her previous lactation. It’s usually calculated as an intra-herd correlation or a correlation between recordings from the same animal over multiple lactations. To maximize the profitability of dairy crossbred cattle, getting a better understanding of the factors that influence reproduction is critical. Skilled people raised and cared for the animals in identical feeding and management conditions. Calving interval (CI), service period (SP), dry period (DP), and days- open were the reproductive features investigated. The data revealed that the repeatability (r) with standard error (SE) for the calving interval (0.60± 0.71), service period (0.20, 0.140), dry period (0.14, ± 0.33) and days-open (0.94 0.14), had moderate repeatability. The calving interval, service period with low repeatability, dry period, and days open with high repeatability are all variables to consider.

    Investigating the Efficacy of Herbal Preparation (Phyllanthus emblica and Curcuma longa) Powder Supplementation on Caged Broilers
    (The Association of Mastitis, 2023-11) Gautam, A.; Neeraj; Pandey, R.; Sushma; Singh, R.P.; Singh, A.K.
    Research study was conducted at the Department of A.H. and Dairying, Sam Higginbottom University of Agriculture, Technology and Sciences, Small animal Nutrition laboratory at Prayagraj, India. The aim was to evaluate the efficacy of herbal preparation (Phyllanthus emblica and Curcuma longa) powder supplementation on caged broilers. The experiment involved four sets of day-old chicks, with each set comprising four groups: T0, T 1, T 2 and T3 . The chicks in group Treatment0 were provided with a basic diet (as per FSSAI Specification), whereas chicks in Treatment1, Treatment 2 , and Treatment3 were fed a Controlled diet enriched with Indian gooseberry powder and Haldi powder, each single chick of them with an amount of 0.50%, throughout a four-week study period. Quantity of feed consumed each week and weekly records of the weight growth of the birds in each group were kept, and the feed conversion ratio (FCR) was calculated. The results of the study indicated significant variations in the average weight gain and FCR among the different treatment groups. Further analysis and interpretation of the data provided valuable insights into the efficacy of (Phyllanthus emblica and Curcuma longa) powder supplementation on the expansion efficiency of caged broilers.

    Serological Evidence of Foot-and-Mouth Disease Virus Nonstructural Protein Antibodies in Indian Elephants (Elephas maximus indicus)
    (The Association of Mastitis, 2023-09) Rout, M.; Deka, P.; Nair, N.S.; Karikalan, M.; Manjunatha, V.; Sahoo, N.; Sharma, A.K.; Mohapatra, J.K.; Singh, R.P.
    Foot-and-mouth disease (FMD) remains one of the most economically devastating menace in livestock due to its highly contagious nature with multispecies involvement. In the present study, a serological survey to detect antibodies against structural and non-structural protein (NSP) of FMD virus (FMDV) in elephants was conducted. A total of 255 elephant serum samples from 5 different states of India were collected with due permission from the competent authorities. A competitive ELISA using commercial kit PrioCHECK� FMDV NS (Prionics AG, Switzerland) was performed to assess antibodies against FMDV 3ABC non-tructural protein. A total of 2.74% (7/255) animals were found positive indicating their previous exposure to FMDV. The serum samples were also subjected to in-house liquid phase blocking ELISA to assess the level of protective antibody against FMDV serotypes O, A and Asia 1, where none of the animals was found to have protective antibody (log10 titre of ?1.8) against all three serotype strains used in the vaccine formulation. In conclusion, the study gathered a low level of serological evidence of virus activity as well as lack of protective antibody against FMDV in the sampled elephants. Further investigations into the dynamics of anti-FMDV antibodies supplemented with virological examination should be carried out to understand the virus ecology and disease epidemiology. In order to establish absolute freedom from infection, oesophageal-pharyngeal fluid collected from the NSP-positive animals could further be examined for the presence of viral genome by polymerase chain reaction or for virus isolation to understand the carrier status in this species.
