“…Intestinal health has also been enhanced with gluconic acid and its salt [26], avoiding the occurrence of a "leaky gut" [27]. In fact, gluconate supplementation has been shown to enhance the performance and health of piglets [28] and its inclusion before weaning enhanced the growth of heifers after the end of supplementation [29].…”

We compared the effects of milk-feeding in 288 Holstein calves (72 per group) which were fed twice (2F) or thrice (3F) daily, with or without the addition of hydrogenated fat-embedded calcium gluconate (G) supplemented in the starter food and in the daily diet up to the age of 9 months, on the calves’ metabolism, growth, health, and reproductive efficiency up to first pregnancy. The calves received 6 L of milk replacer (130 g/L) and had ad libitum access to water and textured calf starter with or without gluconate. Gluconate supplementation promoted a “catch-up” in growth in supplemented calves compared to their counterparts that did not receive gluconate. Gluconate appeared to reduce animal metabolic stress during key events, such as weaning and transfer into open-door pens, reducing fructosamine (352.61 vs. 303.06 in 3FG and 3F, respectively; p = 0.028) and urea (3F revealed the highest values compared with the other three groups: 19.06 for 3F vs. 13.9 (2F), 13.7 (2FG), and 14.3 (3FG), respectively, p = 0.002) from weaning onwards. The feeding of dairy calves with milk replacer three rather than two times per day tended to be associated with better health from weaning to 4 months old; parameters such as ultrasound lung score and calf health score improved over time (p < 0.001). Thrice-daily feeding with milk replacer tended to reduce the number of artificial inseminations per pregnancy in heifers by 0.2 points (p = 0.092). We confirmed significant correlations between early health and growth parameters and reproductive efficiency and a positive correlation between body weight and average daily weight gain and the thickness of the back fat layer in young heifers (r = 0.245; p < 0.0001; r = 0.214; p < 0.0001 respectively). Our study was conducted on a commercial farm with reasonably effective animal management, so baseline welfare was likely satisfactory.

The research was carried out in “Udmurtia” agricultural produc-tion co-operative (collective farm) of the Vavozhsky district of the Udmurt Republic". A complex for keeping 1200 cows with loose cubicle technolo-gy for cow keeping with milking in the milking parlor using the rotary milking equipment was built on the farm for the first time in the Udmurt Republic. In the course of the study, technological operations during keep-ing, feeding, milking cows at the rotary milking unit were studied; the tim-ing of the cow milking process and the sequence of operations were carried out. Based on the research results, specific recommendations were given to the farm.
