Milking management practices and IMI in Jersey crossbred cows in changing scenario

Abstract

Experiment was conducted on Jersey crossbred cows (12) to compare 2 management practices viz. hand andmachine milking. Field investigations were also carried out on other milking management practices, IMI, hygienestatus and cleanliness in 3 stages. A total of 459 milk samples were analysed. Farm experimentation revealed thatSCC and MCMT were significantly higher in hand milking as compared to machine milking management. Butmilk yield and milk extraction rate were significantly lower in hand milking as compared to machine milkingmanagement. The time required for milking/animal was significantly higher in hand milking as compared to machinemilking management. The morning and evening milk samples of both hand and machine milking showed highervalues of SCC, MCMT, pH during evening as compared to morning session but milk yield and milk extraction ratewere lower during evening as compared to morning session whereas time required for milking/animal was higherin morning as compared to evening time. Almost similar trend of fat and SNF (%) were estimated in both milkingsession. Field investigation indicated that SCC, MCMT, pH were higher in IMI animal as compared to no-IMIanimal whereas fat and SNF were lower in IMI animal as compared to no IMI animal. Teat dipping and screeningof udders for mastitis were never followed by any farmer. Most of farmer having single cow, maintained goodhygiene status and cleanliness but most of the farmer having >3 cows, maintained poor hygiene status. Farmexperimentation concluded that the IMI can be reduced in machine milking practices in comparison to hand milkingpractices with higher milk quantity without affecting milk composition in Jersey crossbred cows. Field investigationconcluded that there is a significant association between animal keeping pattern and hygiene status/cleanliness atstudy area. So efforts should be made to increase cleanliness and hygiene status in milking cows itself, housing ofanimal and milkers of farmer’s house to reduce incidence of IMI in changing scenario.

Effect of reducing energy intake during the dry period on milk production, udder health, and body condition score of Jersey crossbred cows in the tropical lower Gangetic region

“…Kumari et al (2019) found that supplementation of trisodium citrate was an effective, easy, and cost-effective management practices to increase milk quality and quantity. Bhakat et al (2017b) reported that the intra-mammary infections (IMI) lead to changes in glandular tissue of the udder. So it is essential to monitor IMI in dairy cows in order to maintain milk quality and udder health.…”

“…The coefficients of correlation (− 0.358) indicated a negative and significant (P < 0.01) correlation between MCMT and milk yield of this study. Bhakat et al (2017b) reported that MCMT grade can be reduced in machine milking practices in Jersey crossbred cows at lower Gangetic region of tropic. Statistically analyzed data (Table 4) revealed that overall significantly (P < 0.01) lesser pH was recorded for treatment than control group milk samples.…”

Factors Affecting Hygienic Milk Production for Farmers of Nadia Dist.

“…The Range of Log SCC (cells / ml) greatly varied between SCM cows (5.01 to 7.56) and on-SCM cows (3.79 to 5.22). Farm experimentation revealed that SCC and MCMT were significantly (P<0.01) higher in hand milking as compared to machine milking management (Bhakat et al, 2017). Following factors in animal housing should be followed to get hygienic milk commercially.…”

Influence of pre and postpartum alpha-tocopherol supplementation on milk yield, milk quality, and udder health of Jersey crossbred cows at tropical lower Gangetic region

“…Adoption of good animal management may improve the overall production and health performance of dairy cows in tropical climate [ 3 - 5 ]. However, due to poor availability of good quality fodder and adverse climatic conditions, it becomes difficult to maintain proper nutrition and management conditions for dairy animals, the farmers of tropical climate [ 6 ]. An approach for Alpha-tocopherol supplementation to dairy cows during the pre and postpartum period has the ability to improve postpartum milk production, udder health, and body condition performance [ 7 ].…”

“…It is a global problem which adversely affects animal health, milk quantity, and milk quality [ 10 ], and every country, including developed ones also, suffers huge financial losses. Particularly for the backyard farmers in the developing world, SCM is one of the most economically devastating problems [ 6 ]. Increased milk demand has given emphasis to crossbred animals, but researches have shown that crossbred animals are more prone to the risk of intra-mammary infection (IMI) [ 11 ].…”
