“…Therefore, the dietary supplementation with SOP at 70 g/cow per day (about 0.35% DMI/day) could not remarkably improve milk productivity and quality under Vietnam dairy husbandry conditions. In agreement with our study, Newton et al (2021) showed that the diet with a small amount of seaweed supplementation (0-158 g/cow per day) for dairy cows was not adequate to improve considerably these parameters. It was also demonstrated that the dietary seaweed supplementation for dairy cows did not affect milk productivity and basic compositions (Lopez et al, 2016;Antaya et al, 2019;Hein, 2021).…”

“…In addition, Baek et al (2004) and Lee et al (2005) indicated that seaweed added 4% DMI/day (800 g/cow per day) into diets of dairy cows significantly increased milk yield, but not milk compositions. Interestingly, Newton et al (2021) revealed that the low supplementation of seaweed (13-40 g/cow per day) did not increase milk yield and quality whereas the dietary high seaweed concentration (26-158 g/cow per day) improved considerably some milk quality parameters (milk protein and casein) without a difference in milk yield and other milk compositions (milk fat, lactose, free fatty acids, SCC). Therefore, there was a wide variation in the effectiveness of SOP supplementation on milk performance and quality in the various supplemented concentrations in recent studies (Baek et al, 2004;Lee et al, 2005;Newton et al, 2021) and only a noticeable enhancement with seaweed supplementation from 90 g/cow per day (equivalent to 0.4% DMI/day) (Cruywagen et al, 2015).…”

The objective of this study was to evaluate effects of dietary supplementation of a seaweed-originated product (SOP) on milk productivity, milk quality and health of milking cows under Vietnam weather conditions at the dairy farm of One Member Dairy and Beef Joint Stock Company HCMC, Vietnam from October 2019 to February 2020. A total of 40 Holstein Friesian crossbred cows were randomly allotted into 2 treatments in a randomized complete block design. The 2 dietary treatments included (1) cows fed a basal ration without SOP supplementation (control) and (2) control plus 70 g SOP/cow per day (about 0.35% dry matter intake/day). Parity, days in milk, body weight, and milk yield of cows in both treatments were almost equal (P > 0.05). The results showed that the average milk yield of cows over the experimental period was not different between the two treatments (P > 0.05), but the lactation stability curve was better in SOP group. The SOP supplementation also did not improve milk quality indicators (fat, protein, solids not fat, lactose, somatic cell count) as compared with the control (P > 0.05). The blood ketone level of cows in the control group was higher than that of cows in the SOP group (P < 0.05), although there were no differences in the blood levels of AST, ALT, protein, glucose, cholesterol, cortisol (P > 0.05). The SOP supplementation did not affect BW, body condition score, and locomotion score as well as the prevalences of lameness and digestive diseases (P > 0.05). Briefly, these results suggest that the dietary SOP addition of 70 g/cow per day appears not to improve milk productivity, milk quality and health of milking cows.

“…In the current experiment, the iodine concentration was 35 mg/kg DM for treatment AN2.5 and 2.75 mg/kg DM for treatment FV2.5. Additionally, it was shown that the iodine concentration in milk follows a dose-response relationship with iodine intake ( Antaya et al, 2015 ; Newton et al, 2021 ). Humans, especially children, are even more sensitive to iodine poisoning than ruminants ( Zimmermann et al, 2005 ).…”

This study aimed to investigate the effects of two brown Icelandic seaweed samples (Ascophyllum nodosum and Fucus vesiculosus) on in vitro methane production, nutrient degradation, and microbiota composition. A total mixed ration (TMR) was incubated alone as control or together with each seaweed at two inclusion levels (2.5 and 5.0% on a dry matter basis) in a long-term rumen simulation technique (Rusitec) experiment. The incubation period lasted 14 days, with 7 days of adaptation and sampling. The methane concentration of total gas produced was decreased at the 5% inclusion level of A. nodosum and F. vesiculosus by 8.9 and 3.6%, respectively (P < 0.001). The total gas production was reduced by all seaweeds, with a greater reduction for the 5% seaweed inclusion level (P < 0.001). Feed nutrient degradation and the production of volatile fatty acids and ammonia in the effluent were also reduced, mostly with a bigger effect for the 5% inclusion level of both seaweeds, indicating a reduced overall fermentation (all P ≤ 0.001). Microbiota composition was analyzed by sequencing 16S rRNA amplicons from the rumen content of the donor cows, fermenter liquid and effluent at days 7 and 13, and feed residues at day 13. Relative abundances of the most abundant methanogens varied between the rumen fluid used for the start of incubation and the samples taken at day 7, as well as between days 7 and 13 in both fermenter liquid and effluent (P < 0.05). According to the differential abundance analysis with q2-ALDEx2, in effluent and fermenter liquid samples, archaeal and bacterial amplicon sequence variants were separated into two groups (P < 0.05). One was more abundant in samples taken from the treatment without seaweed supplementation, while the other one prevailed in seaweed supplemented treatments. This group also showed a dose-dependent response to seaweed inclusion, with a greater number of differentially abundant members between a 5% inclusion level and unsupplemented samples than between a 2.5% inclusion level and TMR. Although supplementation of both seaweeds at a 5% inclusion level decreased methane concentration in the total gas due to the high iodine content in the seaweeds tested, the application of practical feeding should be done with caution.

“…For example, no data exist regarding the effect of key aspects of organic feed (such as white clover) on milk-iodine concentration, or whether the seasonal effects seen in the past are as pronounced today with the increasing practice for year-round housing for dairy cows on large farms. Furthermore, seaweed is starting to be used in farming (e.g., to reduce greenhouse gas emissions), either given to cows or used as a fertilizer on grassland; seaweed use in the dairy industry has been shown to increase milk-iodine concentration ( 78 , 79 ) but further research on ways to incorporate it without risking iodine excess is required.…”

This narrative review summarizes key concepts in dairy nutrition for supporting human health throughout the life course. Milk and dairy products have been a staple component of our diet for thousands of years and provide a wide range of important nutrients that are otherwise difficult to obtain from dairy-free diets. In this review, we provide a broad perspective on the nutritional roles of iodine and dairy protein in supporting human health during pregnancy and early life, childhood and adolescence, mid- and later-life. New methodologies to identify biomarkers of dairy intake via high-throughput mass spectrometry are discussed, and new concepts such as the role of the food matrix in dairy nutrition are introduced. Finally, future policy and research related to the consumption of dairy and non-dairy alternatives for health are discussed with a view to improving nutritional status across the lifespan.
