Strategic administration of antioxidant multiminerals and vitamins to transitional buffaloes augments antioxidant and udder defense mechanisms in early lactation. Res Vet Sci 2024; 172:105253. [PMID: 38579632 DOI: 10.1016/j.rvsc.2024.105253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 03/28/2024] [Accepted: 03/28/2024] [Indexed: 04/07/2024]
Abstract
The aim of the study was to examine the effects of repeated administrations of antioxidant multiminerals and vitamins in transition buffaloes on udder defense mechanism, antioxidant activity and occurrence of intramammary infection (IMI) in early lactation period. Forty clinically healthy pregnant buffaloes were enrolled 45 days before expected date of calving and randomly allocated into five different supplementation groups (n = 8): only basal ration (control), vitamin E and selenium (VES), multiminerals (MM), ascorbic acid (AA) and chromium (Cr) picolinate in basal diet. The udder defense mechanism was monitored by measuring phagocytic activity (PA), myeloperoxidase (MPO) and nitric oxide (NO) productions in milk leukocytes, antioxidant activity was evaluated by measuring total antioxidant capacity (TAC) in plasma and occurrence of IMI was assessed by milk cytology, bacterial count in milk and visible clinical signs of udder until day 28 post-calving. The results showed that the VES and MM supplementations exhibited significantly higher PA, MPO and NO productions of milk leukocytes till first week of lactation whereas, elevated mean TAC in plasma was maintained from day -7 to 1 of calving in MM supplementation group as compared to control group. Statistically, no significant difference in occurrences of subclinical or clinical IMI was noted across the groups until four weeks of lactation. Taken together, it is concluded that repeated administrations of VES and MM to transition buffaloes could be an effective strategy to maintain good udder health by augmenting milk leukocyte functions and antioxidant status and preventing incidence of IMI in early lactation.

Chromium in the Diet of Dairy Calves: Benefits for Growth Performance, Feed Efficiency, Digestibility, and Health. Biol Trace Elem Res 2024:10.1007/s12011-024-04063-1.

Abstract
Chromium (Cr) is a mineral that helps animals subjected to stressful conditions. The suckling period is characterized by several stressful episodes, particularly during the first hours after birth and at weaning. There is little consumption of concentrate by calves in the first weeks of life; consequently, consuming any supplement added to feed would be negligible. Thus, the hypothesis was that the calves would take it in earlier if Cr were consumed in a milk replacer instead. Therefore, our study aimed to determine whether including organic Cr in calf feed (via milk replacer or concentrate) during the suckling phase would improve calf health and growth performance. Twenty-four male Holstein calves with an average age of 8 ± 4 days and 39.8 ± 6.9 kg average body weight were used. Calves were randomly divided into three groups: (a) Chromium-Milk (CR-M), receiving 4 mg Cr/animal/day via milk replacer during the 60 experimental days of suckling (n = 8); (b) Chromium-Concentrate (CR-C), receiving 4 mg Cr/animal/day via concentrate (n = 8); (c) Control (C), animals that did not receive Chromium (n = 8). The experiment lasted 75 days, divided into two well-defined stages: suckling (1-60 days) and weaning (61-75 days). Body weight weekly, daily feed intake, and blood samples taken every two weeks during the experiment were evaluated. At the end of the experiment, the apparent digestibility evaluation was carried out, with the results of weight and consumption carried out, and a feed efficiency analysis was carried out. It was observed that the inclusion of organic Cr (regardless of whether it was milk or concentrate) increased body weight gain (kg) for the CR-C group: 41.8 kg, CR-M: 40.4 kg compared to the C: 34.2 kg (p = 0.01). The protein digestibility was higher in the CR-M group (52%, p = 0.05). Cr consumption increased Cr concentrations in the serum of the calves and was higher in the first week in the animals in the CR-M group. This did not happen for the C group; however, with higher concentrate consumption, Cr concentrations increased and remained high until the end of the experiment. Glucose concentrations were higher in the groups that consumed Cr. Total protein concentrations were higher in the CR-M and CR-C groups than in group C. Immunoglobulin A concentrations were higher in groups CR-C and CR-M than in group C (days 40 and 60). In conclusion, the adding Cr to calf feed improves their health, indirectly favors growth performance, and increases protein digestibility.

Malik MI, Jonker A, Raboisson D, Song B, Rashid MA, Sun X. Effects of dietary chromium supplementation on blood biochemical parameters in dairy cows: A multilevel meta-analytical approach. J Dairy Sci 2024; 107:301-316. [PMID: 37709042 DOI: 10.3168/jds.2023-23545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 08/17/2023] [Indexed: 09/16/2023]
Abstract
Chromium (Cr) has been reported to modulate blood biochemistry in dairy cows. However, there is a discrepancy in the literature regarding the effects of dietary Cr supplementation on various blood parameters. This meta-analysis aimed to evaluate the effects of Cr supplementation in dairy cows on blood glucose, insulin, glucagon, nonesterified fatty acid (NEFA), cortisol, and serum total protein (STP) concentrations. Following relevant literature data extraction, a 3-level meta-analytical random effect model was fitted to the data expressed as standardized mean difference (SMD) of outcome measures of control versus Cr-supplemented cows (i.e., difference in mean between control and treatment group or pooled standard deviation). The SMD can be categorized as having a small effect (0.20), a moderate effect (0.50), and a large effect (0.80). The meta-regression identified the potential sources of heterogeneity, including the body weight of cows, experimental duration/duration of Cr supplementation, blood sampling time (3 wk before parturition until 4 wk after parturition categorized as the transition period, else as the nontransition period), and form of Cr complexes. Blood glucose did not differ significantly between control and Cr-supplemented cows with an estimated SMD of μ = 0.0071 (95% confidence interval [CI]: -0.212 to 0.226). The effect of Cr supplementation on blood insulin was also nonsignificant with an SMD of μ = 0.0007 (95% CI: -0.191 to 0.193). Cows receiving Cr supplements had significantly higher levels of glucagon than controls (95% CI: 0.116 to 0.489), with an estimated SMD = 0.303. Combined transition and nontransition data suggest Cr supplementation did not affect the concentration of NEFA. However, in transition cows, Cr supplementation significantly decreased blood NEFA levels as compared with controls (95% CI: -0.522 to -0.0039), with estimated SMD = -0.263. The estimated SMD was μ = -0.1983 (95% CI: -0.734 to 0.337) for cortisol and -0.0923 (95% CI: -0.316 to 0.131) for total protein. In summary, Cr supplementation in the transition cows decreased NEFA concentration. Blood glucose, insulin, cortisol, and STP concentrations were unaffected. However, Cr supplementation increased glucagon concentration.

Abstract
This study was designed to determine the effects of dietary hazelnut oil (HO) and sunflower oil (SO) on the mineral composition of chicken femur and tibia bones. A 40-day trial was initiated with 600 1-day-old Ross 308 chickens. Initially, the chickens were randomly divided into four main groups of 150 each according to the proportion of SO and HO supplementation in their diets: control SO (25 g/kg SO), LHO (25 g/kg HO), HHO (50 g/kg HO), and MO (50 g/kg blend of 25 g/kg SO + 25 g/kg HO). Each group was further divided into six subgroups of 25 chickens. At the end of the trial, four chickens from each of the six subgroups were randomly selected and slaughtered. Their right tibia and right femur bones were isolated and analyzed for macro (Ca, P, Mg) and trace (Fe, Cu, Mn, Zn, Cr, Co, and Se) minerals in addition to ether extract and ash. The results suggest that the diets' fat concentration and fatty acid composition significantly affected the Ca, P, Mg, Fe, Cu, Cr, and Se composition of tibia bones (p < 0.01). The ether extract and ash contents of the femur bones were increased in both HHO and MO groups (p < 0.05), while Fe and Cr compositions were lower in all femur bones, except those from SO chickens (p < 0.05). The Se content of femur bones in the LHO group was higher than the other treatment groups (p < 0.05). In conclusion, the amount of oil and fatty acid in the diet affected the accumulation of Ca, P, Mg, Fe, Cu, and Cr minerals in the tibia bone. Moreover, the amount of Cr and Fe was lower in the femur and tibia bones in the group that received the HO supplement and all groups in which the amount of oil fed was increased.

Abstract
The objective of the current experiment was to determine the effects of sodium bicarbonate (SBC) and chromium propionate (Cr) supplementation on dry matter intake (DMI), growth performance, blood indices, feed sorting behavior, and digestibility of nutrients during the hot and humid condition in Beetal bucks. Twenty-eight Beetal bucks were randomly assigned to four concentrates treatments (n = 7 bucks/treatment) under 2 × 2 factorial arrangements. The factors were (1) chromium supplementation, basal diet without any supplementation (C) and basal diet with Cr @ 1.5 mg Cr/head/day (Cr), and (2) sodium bircbonate supplementation, basal diet supplemented with SBC @15 g/kg of DM (SBC) and diet containing SBC @ 15 g/kg of DM) and Cr @ 1.5 mg/day/animal (SBC + Cr). Chromium was drenched to each animal during the morning feeding. The average daily noon temperature-humidity index (THI) was 86.37 ± 4.01. The daily DMI and ADG was higher (P < .0001) in the SBC, and trend for daily DMI was observed (P < 0.01) for the Cr. The feed to gain ratio was tended to improve (P = 0.056) by the supplementation of Cr. Plasma glucose, cholesterol, and catalase concentration were lower (P < 0.05) in the Cr supplemented, whereas plasma BUN and TPP were not influenced (P > 0.05) by the Cr or the SBC supplementation. The feed selection index indicated that supplementation of Cr and SBC had no effects on selection or rejection of feed particles. In Cr-supplemented bucks, there was a trend for higher ADF digestibility. Digestibility of dry matter, organic matter, NDF, and ADF were not affected by Cr or SBC supplementation. In conclusion, co supplementation of Cr @ 1.5 mg/d and SBC @ 15 g/kg resulted in highest DMI, ADG and improved the feed efficiency in heat-stressed fattening bucks by alleviating negative impacts of HS.

Abstract
Cow's milk is a highly-nutritious dairy product part of human diet worldwide. Rumen-protected methionine (RPM) is widely used to improve lactation performance of dairy cows, but understanding of the effects of RPM on milk nutrients composition are still limited. In this study, twenty mid-lactating dairy cows were supplemented with 20 gm/day RPM for 8 weeks to investigate the responses of milk nutritional composition to RPM. Metabolomics was applied for analyzing milk metabolites and 16S rRNA gene sequencing was used for analysis of rumen microbial composition. Milk fat content and yield were significantly increased after RPM supplementation. Totally 443 compounds belonging to 15 classes were identified, among which 15 metabolites were significantly changed. The functional nutrient α-ketoglutaric acid were significantly increased in the milk after RPM supplementation. We found 48 significantly differing bacterial genera in the rumen after supplementing RPM. Multi-omics integrated analysis revealed the higher abundance of Acetobacter, unclassified_f_Lachnospiraceae and Saccharofermentan contributed to the improved milk fat. In addition, the enriched abundance of Thermoactinomyces, Asteroleplasma, and Saccharofermentan showed positive correlations with higher α-ketoglutaric acid of milk. Our results uncover the metabolomic fingerprint and the key functional metabolites in the milk after supplementing RPM in dairy cows, as well as the key rumen bacteria associated with them. These findings provide novel insights into the development of functional dairy products that enriched the functional nutrient α-ketoglutaric acid or high milk fat.

Abstract
Chromium may regulate dairy cow metabolism; a chelated formation of chromium methionine (Cr-Met) is available to the feed industry. The objective of this study was to investigate the effect of Cr-Met supplementation on lactation performance, hepatic respiratory rate and anti-oxidative capacity in early-lactating Holstein dairy cows. 64 multiparous cows were assigned to 16 blocks based on parity and milk yield and then the four cows in a block were randomly allocated to four treatment groups with 0, 4, 8 or 16 g/d of Cr-Met per cow supplemented to a basal diet. Cows were moved from an open dry lot to a naturally ventilated tie stall barn 2 weeks before treatment to adapt to this facility, fed and milked at 0630, 1400, and 1930 h every day. The experiment lasted for 12 weeks. Milk yield and composition were recorded weekly. Dry matter intake was measured every 2 weeks for a total of six times throughout the trial. The plasma variables were measured in weeks 4, 8 and 12 of the experiment. Supplementation of Cr-Met did not affect DM intake of cows. As the supplementation of Cr-Met increased, yields of milk, fat, energy corrected milk (P < 0.01) and lactose (P = 0.01) increased in a linear manner. In terms of plasma variables, insulin concentration decreased in a linear manner with Cr-Met supplementation. As for variables relating to hepatic respiration rate, concentrations of pyruvate and NAD in the plasma were increased in quadratic manners, and lactic dehydrogenase activity was linearly increased as Cr-Met feeding levels increased. Moreover, plasma glutathione peroxidase and superoxide dismutase activity were increased in a linear manner. In conclusion, our study suggested that Cr-Met supplementation improved lactation performance of early-lactating dairy cows through enhancing antioxidant capacity and hepatic cellular respiration.

Abstract
Chromium is a micronutrient which has found frequent use as supplements during pregnancy and could have a role in altering the antioxidant status in the brain. The present study was undertaken to estimate chromium levels in the brain, antioxidant enzyme activity with their gene expression, and learning and memory parameters on F1 and F2 generation mice when the F0 was exposed to chromium. The chromium levels in the brain were estimated using atomic absorption spectrophotometer. The enzyme activity of glutathione-s-transferase (GST) and catalase (CAT) was estimated and their gene expression was evaluated using RT-PCR. The spatial memory was tested using Morris water maze. The learning and recall memory was tested using the step down latency paradigm. The chromium levels were significantly raised in animals treated with Cr per se in F1 generation and quercetin cotreatment reduced the Cr levels in brain significantly. The enzyme activity of GST was significantly less in Cr-treated animals of both generations and this effect was significantly reversed on cotreatment with quercetin. The gene expression of GST matched the enzyme activity. However, catalase activity did not show significant decrease with Cr but cotreatment with quercetin resulted in significant decrease compared with control and this effect was not matched by its gene expression. We observed no significant change in learning and memory parameters in both generations following Cr exposure. Thus, this study demonstrates that chromium exposure in gestation causes changes in enzyme activity especially GST and this change was matched by change in gene expression in GST but not CAT. There was no effect on memory at the given dose.
