“…Furthermore, concentration of milk preformed FAs was higher than in mid-lactation dairy cows, as reported by Rico et al (2014). These findings may be the consequence of greater body fat mobilization and NEB of early lactation cows included in the current experiment, as a similar scenario had been reported by Daneshvar et al (2021). Also, estrogens are crucial hormonal regulators of systemic energy homeostasis via regulating adipose tissue metabolism.…”

“…In the present study, milk FAs profile and ketone bodies were evaluated by the FTIR analysis. This method could be useful for evaluating the energy status of cows (McParland and Berry, 2016), especially in early lactating period (Daneshvar et al, 2021). Lower preformed and higher de novo and mixed FAs in milk of FSP-fed cows might be associated with less BW mobilization than 0FSP cows.…”

“…Milk samples were submitted to Ideh Sazan Rojan Alvand Co. (Alborz, Iran) for fat, true protein, lactose, solids not-fat (SNF), total solids (TS), milk urea nitrogen (MUN), NEFA, BHBA, and FAs analyses using Fourier-transform mid-infrared spectroscopy (FTIR) of CombiScope FTIR 600 HP (Delta Instruments, Drachten, The Netherlands). This method could be helpful for evaluating the energy status and NEB in early lactating cows (McParland and Berry, 2016;Daneshvar et al, 2021). Milk composition for each day was calculated from the composite of each milking corrected for milk yield.…”

IntroductionAromatic and herbal plants usage as feed additives have become a new tendency in dairy cows’ nutrition to enhance animal performance. This experiment was performed to study the effects of supplementing fennel seed powder (FSP) to diets during early lactation on performance, milk fatty acid (FA) profile, and rumen fermentation of Holstein dairy cows.MethodsTwenty-four primiparous Holstein dairy cows (10 ± 3 d in milk, 30 ± 2.1 Kg of milk/d, 610 ± 31 Kg body weight; mean ± SE) were balanced for actual milk yield and calving date (n = 8 per treatment) in a complete randomized design. Animals were allocated randomly to diets containing 0 g/d (0FSP), 25 g/d (25FSP), or 50 g/d (50FSP) FSP, individually top-dressed over the total mixed ration. The experimental period was 45 d consisting of the first 15 d for adaptation and the final 30 d for data collection and sampling.Results and discussionDry matter intake responded quadratically to FSP feeding, and cows fed 25FP treatment had greater DMI than 0FSP treatment. The average ruminal pH value decreased linearly as FSP increased in diets. Ruminal valerate and isovalerate proportion increased linearly as FSP inclusion in diets increased, while acetate proportion decreased and acetate:propionate ratio tended to decrease linearly. Increasing FSP in diets linearly increased serum glucose, globulin, and total protein concentrations. Milk yield increased linearly as FSP inclusion in diets increased, whereas milk composition was unaffected. Increasing FSP in diets linearly increased de novo and mixed FA and decreased preformed FA in milk. Dietary treatments did not affect saturated FA, whereas unsaturated FA, mono and poly unsaturated FA linearly decreased with increasing FSP inclusion in diets. Moreover, the content of C18:0 tended to decrease, and C18:1 cis-9 decreased linearly as FSP inclusion increased. Also, increasing the FSP level in diets decreased linearly non-esterified fatty acids and acetone concentrations in the milk. It could be concluded that FSP addition at 50 g/d could enhance performance of early lactating cows.
