“…Most of the blood metabolites were influenced over time in the present study. Previous studies clarified that as pre-weaned ruminant aged, the blood glucose concentration decreased and blood β-hydroxybutyrate concentration increased (51) which is correlated with the greater solid feed intake (52) and consequently rumen development. Overall, we found that there was no interaction between LOS supplementation and RUP:RDP ratios on growth performance of dairy calves showing individual mode of action for each of them in young dairy calves' metabolism.…”

AbstractThe present study evaluated the interaction effects of n-3 fatty acids (from linseed oil (LSO), 0 v. 2·5, % DM basis) with rumen undegradable:degradable protein (RUP:RDP) ratios (low ratio (LR) 27:73; high ratio (HR) 38:62 based on crude protein %) in dairy calves’ starter diet. Forty-eight 3-d-old female Holstein dairy calves (41·5 kg of body weight (BW)) were allocated in a 2 × 2 factorial arrangements in the following treatments (n 12 calves/each): (1) no supplementation of LSO with LR (NLSO-LR); (2) no supplementation of LSO with HR (NLSO-HR); (3) supplementation of LSO with LR (LSO-LR) and (4) supplementation of LSO with HR (LSO-HR). The calves were weaned on day 53 of the experiment and remained in the study until day 73. Intake was not affected by LSO and RUP:RDP ratio. However, average daily gain (ADG) was improved with LSO supplementation. Feeding the HR diet increased ADG compared with the LR diet during the entire period. Final BW was greater in calves fed on the LSO than those fed the NLSO diet. Microbial protein production did not differ among treatments. Calves fed on LSO diets had greater feed efficiency than those which were not fed on LSO diets. The calves supplemented with LSO had greater wither and hip heights compared with the unsupplemented calves. The glucose, cholesterol, HDL and insulin concentrations increased in calves supplemented with LSO. In conclusion, the HR diet improved calves’ performance post-weaning; however, LSO could enhance growth performance of dairy calves during the pre-weaning period.

“…Additionally, the amount of sodium butyrate fed to the treatment animals may not have been optimal. Sodium butyrate was found to have significant effects on in vitro evaluation of intestinal microbiota of weanling pigs and on in vivo rumen function characteristics of weanling lambs fed sodium butyrate at rates ranging from 1 to 4 g/kg intake (Biagi et al, 2007;Soltani et al, 2017). The current study provided the equine treatment subjects with coated sodium butyrate at a rate of approximately 18 g/kg intake.…”

The in vitro gas production technique (IVGPT) has been a valuable tool in ruminant nutrition research for decades and has more recently been used in horse nutrition studies to investigate fermentation activities of the equine hindgut though primarily using feces as inoculum. This study was conducted to evaluate the use of equine rectal content in the IVGPT system as a viable inoculum that can be considered representative of the activities throughout the equine hindgut. Additionally, the study was conducted to measure the effects on fermentation kinetics and end-product production using inoculum from horses fed supplemental levels of coated sodium butyrate in an IVGPT system. Eight warmblood horses were fed a diet consisting of haylage (1% DM intake based on ideal body weight [BW]) and a mash concentrate formulated to provide 2.5 g nonstructural carbohydrate (NSC)/kg BW per meal. The diet was intended to create a NSC challenge to the microbial populations of the hindgut. The horses were randomly assigned to treatment or control group and after a 1-wk diet-adaptation period, the treatment group received 0.4 g/kg BW per day of a coated sodium butyrate supplement, while the control group received a placebo (coating only). After a 3-wk treatment period, the animals were sacrificed and digesta from the cecum, left ventral colon, right dorsal colon, and the rectum were collected within 30 min postmortem and used as inocula for the IVGPT trial. Haylage and concentrates fed to the test animals were also used as substrates in vitro. Sodium butyrate supplementation was not significant for gas production parameters or VFA measured suggesting no effect of sodium butyrate supplementation on the extent or kinetics of gas production or microbial end-product production (P ≥ 0.073). Differences in inocula were significant for organic matter corrected cumulative gas production (P = 0.0001), asymptotic gas production of the second phase (A2) (P < 0.0001); and maximal rate of OM degradation of the second phase (Rmax2) (P = 0.002). Inocula had a significant effect on total VFA (P = 0.0002), butyrate (Bu) (P = 0.015), branched chain fatty acids (P < 0.0001), pH (P < 0.0001), and ammonia (NH3) (P = 0.0024). In conclusion, based on observed results from this study, total tract digestibility may be overestimated if using rectal content inoculum to evaluate forage-based feeds in an IVGPT system.

“…Feeding diets high in NDF and low in NFC resulted in increase in acetate and decrease in propionate in the rumen et al, 2017;Soltani et al 2017). However, the absence of a difference in propionate concentrations between the control and experimental groups at day 56 in this study could be attributed to the similar starter feed intake of calves.…”

The objective was to evaluate the effect of free-choice provision of different forage sources [(alfalfa hay (AH) or grass hay (GH)] in preweaning period on performance and rumen fermentation of dairy calves. Twenty-one Individually housed Simmental calves (46.69 ± 4.14 birth weight, 3 days old) were randomly divided into 3 treatments of 7 calves each: Control: pelleted starter without forage, GH: pelleted starter + GH and AH: pelleted starter feed + AH. The study continued from 3 days of age to 56 days of age. All calves were fed 2 × 2.6 L of whole milk (5.2 L/day) until the end of the experiment. Starter and forage were offered ad libitum in different buckets during the experiment. Feed intake was monitored daily and body weight was measured at the begining and end of the experiment. Ruminal fluid samples were taken from calves on the last day of the experiment. Inclusion of forage in the diet had no significant effect on starter intake, final body weight, body structure, average daily gain (ADG) and feed conversion ratio. Fecal scores were also not affected by the treatments. At the end of the study, calves fed pelleted starter had lower rumen pH than calves fed forage supplemented diets (P<0.001). On the other hand, calves fed with forage-supplemented diets had higher acetate and acetate to propionate ratios than calves fed starter diets alone (P<0.01). The results of this experiment indicate that consumption of 5.74% GS and 6.60% AH of total DMI can improve the rumen environment without affecting starter feed consumption and animal performance, but If larger scale, on-farm studies confirm the results of this study, to achieve maximum growth in the preweaning period, it may be recommended to give the calves GH or AH separately from the starter feed.
