Seasonal assessment of mastitis using thermogram analysis in Sahiwal cows

Research in Veterinary Science, 2023
"India is the world's leading producer of milk" and demands a non-invasive diagnostic tool like infrared thermography (IRT) to identify the costliest production disease, mastitis. It can form the basis of precision dairy farming. Therefore, the present study focuses on thermal imaging of the udder and teat quarters of Sahiwal cows during different ...

Genetic analysis of growth performance of Sahiwal cows

Indian Journal of Animal Research, 2014
In the present investigation, genetic analysis for early growth traits of Sahiwal cows were performed using mixed linear model. The overall least squares means for body weights at birth (BW), 6 (W6), 12 (W12), 18 (W18), 24 (W24), 42(W30) months and weight at first service (WFS) were 20.59±0.27, 82.29±2.64, 136.98±3.26, 204.83±2.77, 252.27±3.24, 314.16 ...

Prevalence and Diagnosis of Subclinical Mastitis in Sahiwal Dairy Cows

International Journal of Livestock Research, 2018
The present study was conducted on 102 Sahiwal dairy cows to assess the prevalence of subclinical mastitis, type of bacteria present and ability of different parameters to diagnose subclinical mastitis. The prevalence of subclinical mastitis was found to be 43.12% animal wise and 18.14% quarter wise. The coagulase negative staphylococci (CNS) were the

Colostrum and milk composition during postpartum period in Hill cow, sahiwal and crossbreds cow

Indian Journal of Animal Research, 2015
The study was undertaken to determine the composition of colostrum and milk of Hill cattle during postpartum period and compared them to Sahiwal and crossbred cow. Fifteen colostrum samples per day from each group of cow (as per availability) were collected during first five postpartum days while as milk samples were collected from eight cow each of ...

Influence of environment and heredity on the shape of lactation curves in Sahiwal cows

The Journal of Agricultural Science, 1979
SummaryThe shape of the lactation curve of Sahiwal cows was estimated by fitting a gamma function to 2034 lactations made by 681 cows at two farms in Indo-Gangetic plains of Northern India. The persistency of lactation yield was estimated by three methods: P1, the coefficient of variation among weekly yields; P2, ratio of lactation yield to peak yield,

Prospects of raising Sahiwal cow calves for veal production under tropical environment

Tropical Animal Health and Production, 2012
The objective of present study was to evaluate the growth potential of Sahiwal calves for veal production on whole milk or whole milk and milk replacer combined in a ratio of 50:50 (MMR). For this purpose, 48 Sahiwal calves (both male and female) were assigned to four dietary treatments having 12 animals/treatment. Calves in the treatments A and B were

Behavioural Pattern as Indicator of Different Stages of Estrus in Sahiwal Cows

Indian Journal of Animal Production and Management
The reproductive efficiency of dairy animals  is having a direct impact on productivity and  profitability of dairy farms. Therefore, reproduction  management is a major concern in dairy industry.  Communication of the timing of physiological event  of ovulation and coordination of sexual behavior are  important for successful fertilization.

Genetic Evaluation of Reproductive Performance and Milk Production in Sahiwal Cows

Indian Journal of Animal Research
Background: Genetic parameter and covariance component estimation is an important aspect of animal breeding, as it helps to quantify additive and non-additive genetic variances. The precise estimation is also essential for reliable prediction of breeding values.

Effect of Different Synchronisation Protocols on Embryo Transfer in Sahiwal Cows

UTTAR PRADESH JOURNAL OF ZOOLOGY
The present study was conducted to compare CIDR + Ovsynch, Double PG protocol’s synchronisation effect on recipient cows after IVF-ET (Invitro Fertilization - Embryo Transfer). Since there is a positive effect of synchronisation on conception rate, protocol with higher synchronisation efficiency and conception rate can be determined under this study ...
