“…The highest increase in albumin, total protein, and globulin at 400 g/d could indicate amla fruit's positive effect on improving protein utilization efficiency, and may improve liver function. Moreover, our previous result using the same experiment animals also showed increased milk nitrogen efficiency and milk protein, while reducing NH 3 -N, milk urea nitrogen, and protozoa population counts at 400 g/d FAF dose [28]. Similarly, buffalo calves supplemented with phytogenic feed additives rich in tannins, saponins, and essential oils containing fruit pulp of amla as one component found higher values for total protein, albumin, and globulin compared to the control group [29].…”

“…In addition, Szczechowiak et al [54] reported that using a mixture of condensed tannins (Vaccinium vitis idaea) and oils blends for dairy cows significantly increased blood glucose levels. Increased blood glucose in this experiment may have been the consequence of elevated propionate production or organic matter (OM) digestibility for 200 or 600 g/d FAF dose from our previous published result [28]. Moreover, the high glucose concentration for 400 g/d FAF dose in the current experiment was probably due to greater amounts of absorbed amino acids in the gastrointestinal tract of animals, as noted by Zhang et al [73], which needs to be further investigated.…”

“…We previously reported that fresh amla fruit supplementation did not affect feed intake by Holstein dairy cows, but it had a dose-dependent effect on milk production, milk composition, apparent nutrient digestibility, milk nitrogen efficiency, milk urea nitrogen, ruminal short chain fatty acid production, ammonia production, and protozoal counts [28]. In a study performed on buffalo calves, phytogenic additives containing amla fruit enhanced immune status, and increased metabolite concentrations in the blood, such as total protein, albumin, globulin, aspartate transaminase, and alanine transaminase [29,30].…”

“…The eight cannulated lactating cows were randomly assigned to one of two treatments (control or supplemented) in a repeated crossover design. For all groups, we used the same total mixed ration (TMR) diet (Tables 1 and 2, previously used from Tilahun et al [28]), formulated using AMTS Cattle Pro version 4.14 (2018, AMTS LLC, Groton, NY, USA) and prepared using a feed mixer on a daily basis based on cows' nutritional needs to produce 25 kg milk daily with a target of 3.5% milk fat and 3.1% milk protein. Experimental treatments were: (1) control-TMR with no amla fruit (0 g/day); (2) supplemented group-TMR supplemented with fresh amla fruit (FAF) administered as a top dress, in sequential order at three dose levels (200 g/d, 400 g/d, or 600 g/d, as-fed basis) (Table 3).…”

The objective of this study was to investigate the effect of a diet supplemented with fresh amla fruit as a natural feed additive on blood metabolic parameters, milk antioxidant capacity, and milk fatty acid (FA) proportions in lactating dairy cows. Eight ruminally cannulated mid-lactation dairy cows were used in a repeated crossover design. The first group of four cows received total mixed ration (TMR) feed without fresh amla fruit (control group). The remaining four cows sequentially supplemented fresh amla fruit (FAF) at three levels (200, 400, then 600 g/d) (treatment group) at 14-day intervals. In second period, control and treatment groups were exchanged. The first ten days were adjusted to diet adaptation for each sub-period, and the last four days for sampling milk and blood. A total of 514 metabolites were detected from FAF using UPLC-ESI-MS/MS. The five main metabolites in FAF were phenolic acids (22%), flavonoids (20%), lipids (20%), amino acids and derivatives (9%), and tannins (7%). Amla fruit supplementation reduced total saturated fatty acid and the omega-6/omega-3 ratio at 200 or 400 g/d FAF dose compared to controls. In addition, amla fruit increased unsaturated FA, such as C20:5 (Eicosapentaenoic acid, EPA) and C22:6 (docosahexaenoic acid, DHA), and branched-chain FA in a dose-dependent manner at 200 or 400 g/d compared to controls. In addition, amla fruit increased the antioxidant capacity biomarkers in the blood, such as superoxide dismutase (SOD) and albumin; this confirms that amla fruit is an excellent antioxidant, inhibiting reactive oxygen species’ (ROS) metabolism, and can thereby protect cells from oxidative stress. Moreover, the most remarkable improvement of ferric reducing-antioxidant power (FRAP) and total antioxidant capacity (TAC) in milk was recorded at 400 g/d FAF doses compared to controls. Therefore, fresh amla fruit doses for lactating cows at 400 g/d on an as-fed basis can be used as an alternative additive feed in dairy cow diets to improve antioxidant capacity, protein efficiency, butter quality, and to produce more desirable milk fatty acid profiles for human consumption.

“…VFA concentration depends on nutrient digestibility (particularly that of carbohydrates), VFA absorption rate, the ruminal microbial community activity, and degradation rate (Tilahun et al 2022). The in vitro VFA means of beef cattle ration based on local feedstuffs obtained from ANOVA were T 5 = 150.5 mM, T 4 = 133.0 mM, T 3 = 130.5 mM, T 2 = 130.0 mM, and T 1 = 123.5 mM.…”

Background: Optimum productivity of beef cattle is achieved with adequate feed supply, both in quality and quantity. Consumption of local feedstuff Neptunia plena L. Benth and Leersia hexandra Swartz as a ration by the animal subject is expected to promote cost efficiency and production, as well as provide essential nutrition needs. Therefore, this research aimed to evaluate dry matter digestibility (DMD), organic matter digestibility (OMD), N-NH3 production, and volatile fatty acid (VFA) in beef cattle. Methods: Feed and rumen inoculum samples were prepared and analyzed for their proximate contents. There were five treatment groups based on the diet received by beef cattle. In vitro approaches were used to determine the DMD, OMD, N-NH3 production, and VFA in beef cattle. The research was conducted in the Laboratory of Feed Nutrient Science, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The data were analyzed using ANOVA at a significance level of 95%, and a Duncan Multiple Range Test. Results: The results showed that the highest DMD (P<0.05) was derived from T5 (56.47%), followed by T4 (56.45%) and T3 (55.90%). T5=62.40% significantly (P<0.05) generated the highest OMD followed by T4=61.95% and T3=60.82%. This treatment had the highest N-NH3 value, namely 5.02 mM, compared with T3=4.55 mM, T4=4.50 mM, T2=4.22 mM, and T1=3.99 mM. Furthermore, T5 had the highest VFA (P<0.05) compared with T4, T3, T2, and T1 with the value of 150.5, 133.0, 130.5, 130.0, and 123.5 mM, respectively. Conclusions: The local feedstuff-based ration contributed to beef cattle production.
