“…However, it has been reported that blood P concentration was lower in multiparous Holstein cows [ 50 , 51 ]. Additionally, P concentration showed no significant correlation between blood and milk, and further discussion is needed to investigate it [ 14 ]. Likewise, K concentration in multiparous buffaloes also exhibited variations compared with primiparous (18.41 g/100 g versus 16.20 g/100 g) ( p = 0.05).…”

Colostrum is a vital performance for buffaloes and potentially functional foods in the future. Therefore, this study aimed to evaluate the difference between the parity of buffalo colostrum and mature milk. Twenty pregnant buffaloes (primiparous = 10; multiparous = 10) were assigned to the same diet prepartum and milking routine postpartum. Calves were separated from the dams immediately after birth and colostrum was harvested within 2 h, whilst mature milk was harvested at 7 days postpartum. The colostrum was analyzed for immunoglobulin G and milk composition as the mature milk. The results showed that there was a higher level of protein, solid not fat, and milk urea nitrogen (p < 0.05), with a tendency for higher total solids (p = 0.08) in primiparous buffaloes’ colostrum compared with multiparous. No parity effect was observed in colostrum immunoglobulin G, fat, lactose, and yields of colostrum and composition (p > 0.05). There was no difference in mature milk composition and yield by parity affected (p > 0.05). Compared with mature milk composition, colostrum had a higher content protein, total solids, solid not fat, and milk urea nitrogen (p < 0.05); however, fat and lactose were lower than that of mature milk (p < 0.05). For minerals, multiparous buffaloes’ colostrum had a higher concentration of Fe (p = 0.05), while the mature milk had higher concentrations of K and P compared with primiparous. Buffalo colostrum had higher concentrations of Na, Mg, Co, Fe, and K with a lower concentration of Ca relative to mature milk (p < 0.05). It was observed that parity affected colostrum characteristics rather than mature milk and caused subtle variations in minerals in colostrum and mature milk of buffaloes. As lactation proceeded, both milk composition and minerals in the milk changed drastically.

“…The mineral content of mature milk is also related to milk quality and physicochemical indicators [ 12 ]. Although studies have shown changes in the minerals of Holstein cows’ milk [ 13 , 14 ], parity as an influencing factor in buffaloes has not been studied.…”

“…This is the main source of nutrition for baby mammals, including humans, before they can digest other types of food [1]. Early lactation milk contains colostrum [2], which carries maternal antibodies to its young and can reduce the risk of many diseases [3]. It contains many other nutrients, including protein and lactose [4], [5].…”

The background of this research is to understand the operation process, which is the main goal of developing the process model. This model is often used for operator training, process design, safety system analysis, or control system design. The dynamic model of the milk cooling process from 36˚C to 4˚C using chilled water available at 2˚C was performed. Chilled water was maintained at a constant temperature by using a refrigerant unit. The process being investigated was a Packo brand milk cooling tank belonging to KUD SAE Pujon (Malang -Indonesia). A fundamental heat balance method was used to derive the model, leading to a first-order transfer function process. For a 2-hr cooling process, the gain and time constant values are 1.00 and 42.3548 mins, respectively. Heat balance was then extended to continuous processes so that its transfer function could also be obtained. This study simulated and investigated the behavior of batch and continuous processes. Process Identification via input-output data was also introduced for continuous process. The process model obtained from the system identification toolbox was very useful in control, such as for determining tuning parameters via the Ziegler-Nichol method for Proportional-Integral control. However, a small delay was required to be introduced to the system as the first order process without time Ziegler Nichol method cannot be implemented. Further research may include other system identification methods, such as ARX, ARMAX, Output-Error, Box Jenkins etc., or implementing advanced process control for milk cooling.

“…Processes such as colostrogenesis, milk synthesis, immune activation, or inflammation challenge the homeostatic and homeorhetic mechanisms responsible to maintain blood calcium (Ca) concentration, and may lead to low blood Ca concentration during the peripartum period ( Horst et al, 2020 ; Valldecabres and Silva-del-Río, 2022 ). Low blood Ca concentration postpartum has been associated in epidemiological studies with undesired outcomes such as increased risk of diseases and reproductive inefficiency ( Rodríguez et al, 2017 ; Valldecabres and Silva-del-Río, 2021a ).…”

Graphical Abstract Summary: Meta-analytical methods were used to quantify the associations between prophylactic blanket postpartum oral Ca bolus supplementation and milk yield and risk of pregnancy to first service in dairy cows. Nine relevant studies were identified following a systematic review of the literature published between January 2010 and September 2021. Eight of the eligible studies reported feeding low or negative dietary cation-anion difference diets prepartum. The meta-analyses revealed a lack of evidence for a group level response on milk yield or risk of pregnancy to first service after prophylactic blanket postpartum oral Ca bolus supplementation. Future research should study and report the production, reproduction, and health estimates of cow-level conditional factors of interest for the evaluated response, and investigate alternative regimens of oral Ca bolus supplementation.
