“…Triglyceride values higher than measured in this study were observed in induced crossbreed cows (Oliveira 2017), and they associated this increase with the reduction of lipase lipoprotein activity in adipose tissue due to the use of estradiol during the protocol. The BCS reflects the energy balance of the animal (Jeong et al 2015). Values similar to those obtained here were reported in cyclic postpartum cows (Jeong et al 2015) and for induced crossbreed cows (Oliveira 2017).…”

The objective of this study was to determine the biochemical profile of dairy cows with induced lactation. For comparison, another group of normally calved cows was used as control. Lactation was induced in multiparous Holstein cows (n=10) with two norgestomet implants (3mg each implant) on day 1. The testing continued with intramuscular norgestomet (3mg/animal) on days 1, 3, 5, 7, 9, 11, 13 and 15. On days 1, 9, 16 to 18 and then every 14 days, bSTr (500mg/animal) was added. On day 16, the intravaginal implant was removed and intramuscular prostaglandin F2α (0.530mg/animal) and intramuscular estradiol benzoate (5mg/animal) were added. On days 16 to 18 dexamethasone (10mg/animal) was added, and from days 18 to 20 intramuscular metoclopramide (100mg/animal) was added. Milking began on day 19 of the induction. Blood was collected for a biochemical profile after 21 days in milk. It was found that urea and triglyceride concentrations were significantly higher in the induced cows (P<0.05). Therefore, it was concluded that the animals that had lactation induced did not present disorders related to the biochemical profile indicating that the hepatic function, renal function and lipidogram of the animals were not affected by the use of the drugs to induce lactation.

“…In contrast with this evidence, we did not observe statistical differences in NEFA due to the addition of the organic RPF. Regarding NEFA concentrations, this study population seems to have lower NEFA levels compared to some studies that have evaluated the role of NEB on post-partum diseases [30, 31]. However, a comparison of NEFA concentration should consider the productive system to which cows are subject.…”

The effect of an organic rumen-protected fat supplement on performance, metabolic status, and health of dairy cows

et al. 2019

BackgroundNegative energy balance during the transition period is a concern for both conventional and certified organic dairy systems. During early lactation, supplemental strategies are used to cope with nutrient deficiencies that are associated with impaired health, production, and reproduction. As organic certified dairies in the United States face restricted access to dietary supplements, the evaluation of products especially formulated for organic production is needed. Our objective was to assess the effect of supplementing 0.45 kg/d of an organic rumen-protected fat (RPF) on health, metabolic status, and productive and reproductive performance of organic certified Holstein cows from 1 to 150 days in milk (DIM). Two-hundred and two cows were enrolled in a randomized blocked controlled trial conducted from January to July 2017 in a certified organic dairy located in Northern Colorado (USA). Two groups were randomly assigned to be individually supplemented with organic RPF (ORG; n = 100) or control pellets (CON; n = 102) once per day, in addition to the total mixed ration (TMR). Outcomes of interest included milk yield (kg/d) and milk components, serum concentration of glucose, and non-esterified fatty acids (NEFA), resumption of cyclicity, time-to-first artificial insemination (AI), conception at first AI, and conception within 150 DIM, disease occurrence, culling, mortality.ResultsA significant effect for the inclusion of RPF was found in daily milk yield; RPF supplemented cows had greater milk yield (1.6 kg/d) compared to CON cows up to 150 DIM (P = 0.03). During grazing, multiparous (MP) ORG cows had greater milk yield compared to MP CON cows, whereas no effect was found in primiparous (PP) cows. Health outcomes, serum metabolite concentrations, and reproductive performance were not affected by the inclusion of RPF. Body condition loss was smaller in the ORG group up to 80 DIM; however, there was no effect on body condition during the grazing season and in the overall study period.ConclusionsThese results indicate that supplementation of RPF increased daily milk yield and prevented body condition loss during at 90 DIM. However, RPF supplementation did not affect health, serum metabolite concentration, milk components, and reproductive outcomes.

“…However, average cholesterol concentrations between weeks 5 and 6 were comparatively less in cyclic cows. Jeong et al [4] reported that non-cyclic cows had lower total cholesterol than the cyclic cows. Cholesterol is a precursor of ovarian steroidogenesis.…”

“…In early lactation stage, the nutrient demand may increase and the body reserves are usually utilized which ultimately creates a great problem for reproduction, production, and general welfare in high-yielding dairy cows [3]. Delayed resumption of postpartum cyclicity (RPC) has been associated with severe NEB which ultimately negatively affects the postpartum metabolism and reproductive efficiency [4]. Cow fertility is directly related to health during the early postpartum period.…”

Changes in postpartum metabolites and resumption of ovarian cyclicity in primiparous and multiparous dairy cows

2018

The postpartum period in high-yielding dairy cows creates an enormous drain of nutrients in favor of milk yield which antagonizes the resumption of ovulatory cycles. Therefore, a study was undertaken to evaluate the association of changes in postpartum serum metabolites with resumption of ovarian cyclicity. A total of 24 clinically healthy, freshly parturated primiparous (P-1) and multiparous (P-2) Holstein Frisian cows was selected. Cows were further divided on the basis of body condition score (BCS) 1 and 2 having BCS 3 or above 3, respectively. Weekly blood samples were collected and serum glucose, cholesterol, triglycerides, progesterone, and cortisol concentrations were determined for a period of 7 weeks. The glucose concentration was significantly (P \ 0.05) higher in cows in P-2 during week 7. Cows in parity 2 had significantly (P \ 0.05) high cholesterol during week 6 and 7. The serum triglyceride concentration in multiparous animals having BCS-2 during week 6 was increased significantly (P \ 0.05). Serum cortisol was significantly (P \ 0.05) high in P-1 during week 1 and 2 and significantly (P \ 0.05) high in P-2 during week 7. Serum progesterone was significantly (P \ 0.05) higher in cows during week 7 in P-2 having BCS-2. The increased serum progesterone concentration during postpartum period was associated with decreased levels of serum cortisol and more availability of cholesterol and glucose. The multiparous cows maintained the postpartum blood metabolite concentration and showed better adaptability to reproductive cyclicity during the postpartum period as compared to primiparous cows.
