AbstractAutomatic cluster remover (ACR) settings regulate the end of milking by detaching the clusters based on milk flow dropping below a preset level, which needs to be standardised for different breeds of dairy animals based on their production. A study was conducted to find out the best ACR setting for milking Indian crossbred cows based on milkability, milking irregularities and milk quality. Fifty six crossbred dairy cows in lactations 1 to 4 were categorised into three groups based on the level of production; low (N = 16; <12 kg/d), medium (N = 32; 12–18 kg/d) and high (N = 08; >18 kg/d). The ACR settings tested were 0.1, 0.2, 0.3 and 0.4 kg/min, keeping the vacuum level and pulsation settings constant. The ACR settings significantly (P < 0.01) affected the milk yield at all levels of production with a significant effect (P < 0.01) on machine-on time at 0.4 kg/min. The yield during the first 2 min of milking, average flow and peak flow rates were not affected at any level of production. The average electrical conductivity in milk was significantly (P < 0.01) lower for the low and medium yield cows without affecting the mean somatic cell count. At 0.4 kg/min, more cluster reattachments were needed because of significant amount of milk remaining in the udders post-cluster removal.

The productive and reproductive performances of dairy animals have direct effect to milk production and profitability of dairy enterprise. The present study was carried out to analyse the productive and reproductive performance of cattle and buffaloes reared under farmers’ management in three states of differential dairy progress in India. Haryana, Maharashtra and Odisha states were purposively selected from highly, moderately and least dairy progressive states, respectively. The total sample size was 900 containing 300 dairy farmers from each state. The finding shows that the productive and reproductive performances of buffalos in Haryana are better than Maharashtra and Odisha. The productive and reproductive performances of Crossbred were found better in Haryana as well as Maharashtra than Odisha. In Haryana, very few farmers reared Indigenous cattle but the performances were better than Maharashtra and Odisha. The better performance of Haryana may be due to being home track of elite Murrah buffalo, Tharparker and Sahiwal breeds of Indigenous cattle, agro-climatic situations, veterinary services and managerial skills of dairy farmers. To improve the productive and reproductive performance of dairy animals in the moderately progressive (Maharashtra) and least progressive (Odisha) states efforts should be focused on breed improvement, better veterinary infrastructure and enhance the managerial skills of the farmers

Main Factor

Background: In lactating animals, the majority of factors like nutrient intake, physiological health, housing management and atmospheric conditions affect reproductive performance of the animal. In dairy animals the main factor affecting reproduction is nutrition status that too trace minerals. So to have a good return from the livestock trace minerals with balanced feeding of the animals must be done. Optimum feeding of minerals with respect to the various stages of reproductive life cycle must be done to increase the reproductive performance. Methods: Hence, present research trial was carried out at the Dairy farm of Banaras Hindu University, Dist. Varanasi (Uttar Pradesh). 24 Cross bred (Sahiwal × HF) non-cyclic, non-pregnant cattle, ranging 3 - 6 years of age were randomly selected to assess the role of trace minerals in fertility of infertile cows. Result: It is observed from the study, total 24 infertile crossbred cows were selected to induce oestrus taken for correction of anoestrosity with incorporated minerals. Total 8 out of 24 animals exhibited oestrus symptoms after the treatment. Among the animals received incorporated mineral (treatment group) 50% showed the oestrus symptoms. Among the animals under control 16.66% came into heat.

Offspring Health

Nutritional status can have major implications for animal health and production. Energy balance is easily determined using a body condition scoring system. This allows producers to readily adjust diets to meet an animal’s needs. Far less obvious is an animal’s trace mineral status, which is typically not assessed until an animal’s performance falls below expectation or illness is detected. Trace mineral toxicities and deficiencies can manifest as reduced thriftiness and/or poor reproductive performance, resulting in economic consequences for producers. Maternal mineral status not only impacts dam heath, but also the health of subsequent offspring. Both the oocyte and embryo are susceptible to changes in maternal mineral status. This susceptibility is maintained throughout fetal development via placental control of nutrient transfer to the fetal system. Furthermore, maternal mineral status continues to impact offspring health via colostrum and milk quality. Herein we discuss the roles of trace minerals in bovine reproductive performance, maternal health, colostrum and milk quality, and offspring health.

Intramammary infection (IMI), comprises a group of costly diseases affecting dairy animals worldwide. Many dairy parlours are equipped with on-line computerised data acquisition systems designed to detect IMI. However, the data collected is related to the cow level, therefore the contribution of infected glands to the recorded parameters may be over estimated. The present study aimed at evaluating the influence of single gland IMI by different bacteria specieson the cow's overall milk quality. A total of 130 cows were tested 239 times; 79 cows were tested once and the others were examined 2–8 times. All of the analysed data refer to the number of tests performed, taking into account the repeated testing of the same cows. Of the cows tested ~50% were free of infection in all 4 glands and the others were infected in one gland with different coagulase negative staphylococci (CNS), Streptococcus dysgalactiae, or were post infected with Escherichia coli (PIEc), i.e., free of bacterial infection at the time of sampling but 1–2 months after clinical infection by E. coli. Overall, infection with bacteria had significant effects on somatic cell count (SCC) and lactose concentration. Examining each bacterium reveals that the major influence on those parameters was the sharp decrease in lactose in the PIEc and curd firmness in PIEc and Strep. Individual gland milk production decreased ~20% in Strep. dysgalactiae- and ~50% in PIEc-infected glands with respect to glands with no bacterial findings. Significant differences were found in lactose, SCC, rennet clotting time and curd firmness in the milk of infected glands and among those, these parameters were significantly higher in Strep. dysgalactiae and PIEc than in CNS infected cows. The current results using quarter-milking reinforces the importance of accurate IMI detection in relation to economic and welfare factors, and moreover, emphasises the need for technical sensing and constant reporting to the farmer about changes in the milk quality of every animal.
