In Bharatiya culture (संस्कृति), Gau is worshiped. Her calf is also worshiped. They are never separated. Take any visual depiction, calf will always be there.
On the other hand, greedy dairy industry, promoted and supported by we the moron society, separates calf from mother within 24 hrs.
Here is the paper that talks about detrimental impact. The stress induced in both mother and calf make them immunological weak.
“Research has shown that the early social environment affects behaviour, stress reactivity and the ability to cope with different challenges in various animal species,” says project leader Susanne Waiblinger from the Institute of Animal Husbandry and Animal Welfare. Waiblinger and first author Kathrin Wagner studied these effects in dairy cows. A previously published substudy by the researchers already showed that rearing with maternal contact gives rise to adults with higher social competence.
Animals reared with maternal contact are more active in stress situations
“Cattle are herd animals. As expected, all animals, whether they were reared with or without mothers, produced higher levels of the stress hormone cortisol when being isolated from the herd, ” Waiblinger explains. Cattle which grew up with their mothers expressed the highest levels of cortisol during isolation, but the heart rate measured in these animals was the lowest. Waiblinger explains: “There are fundamentally different reaction types. Some animals respond to stress situations with an increased heart rate, others produce cortisol. It is possible that the different rearing treatments result in different reaction types.”
So those friends who while looking at modern dairy, criticizing ancient gau-seva practices are wrong. They should correct their stand and be open about symbiotic relation between humans and Bos Indicus. I am completely against domesticating wild species like Bos Taurus (European exotic breed).
Mother yielding milk under stress is as good as poison.

Effects of mother versus artificial rearing during the first 12 weeks of life on challenge responses of dairy cows
http://www.appliedanimalbehaviour.com/article/S0168-1591(14)00329-3/abstract
Abstract
We investigated the effects of mother versus artificial rearing on the responses to a social and a non-social challenge in adulthood. Rearing of treatment groups only differed during the first 12 weeks of life. Artificially reared animals were separated from their mothers within 24 h after birth and fed via an automatic milk feeder six times (A6, n = 6) or twice (A2, n = 5) a day. They were housed together with calves suckled by their mothers twice a day for 15 min (M2, n = 9) or with permanent access to the cow barn and thus to their mothers and the cow herd via selection gates (MP, n = 6). After weaning animals of all rearing treatments were kept together until integration into the dairy cow herd. About 4.5 months after calving (age 31 ± 1.4 months), cows were subjected to an isolation test and two novel objects tests (first: traffic cone, second: ball). ANOVA (behaviour; heart rate of novel object tests) and GLMM (heart rate and cortisol responses to isolation) were used for statistical analyses. During isolation, MP cows were more active: they walked significantly longer (P = 0.036), tended to enter more squares in the middle area of the test arena (P = 0.059), and to explore the arena or the outer environment for longer (P = 0.056) than cows of the other three treatments. In addition, MP and A6 cows had the lowest mean heart rate during isolation, whereas after return into the herd the MP cows showed the lowest heart rate. Cortisol levels differed between groups dependent on sampling time (P = 0.001), with MP cows having the lowest basal values but the highest after the isolation test. In the novel object tests, A6 cows tended to explore the traffic cone later (P = 0.051), focused the ball earlier (P = 0.040) and tended to use the area farther away from the ball more often than cows of the other three treatments (P = 0.100). These results in 2.5-year-old cows suggest that rearing with permanent access to the mother and the herd increases sociality leading to higher behavioural activity during isolation and affects physiological stress reactions so that they resemble a reactive coping style, while reaction to novel objects in the home environment is not affected by mother rearing.
Early separation of cow and calf has long-term effects on social behaviour
http://www.vetmeduni.ac.at/en/infoservice/presseinformation/press-releases-2015/early-separation-of-cow-and-calf-has-long-term-effects-on-social-behaviour/
Calves of dairy cows are generally separated from their mothers within the first 24 hours after birth. The majority of the milk thus enters the food market and not the stomachs of the calves. However, growing up without a mother has consequences. Scientists at the Vetmeduni Vienna studied the long-term effects of early maternal deprivation. Their study shows that calves which have contact to their mothers or to other cows during rearing become more sociable adults. The results of the study were published in the journal Applied Animal Behaviour Science.
