AbstractImproving the nutrition of livestock is an important aspect of global food production sustainability. This study verified whether lactic acid bacteria (LAB) inoculant could promote ensiling characteristics, nutritive value, and in vitro enteric methane (CH4) mitigation of forage sorghum (FS) mixture silage in attacking malnutrition in Zebu beef cattle. The FS at the soft dough stage, Cavalcade hay (CH), and cassava chip (CC) were obtained. The treatments were designed as a 4 × 2 factorial arrangement in a completely randomized design. Factor A was FS prepared without or with CH, CC, and CH + CC. Factor B was untreated or treated with Lactobacillus casei TH14. The results showed that all FS mixture silages preserved well with lower pH values below 4.0 and higher lactic acid contents above 56.4 g/kg dry matter (DM). Adding LAB boosted the lactic acid content of silages. After 24 h and 48 h of in vitro rumen incubation, the CC-treated silage increased in vitro DM digestibility (IVDMD) with increased total gas production and CH4 production. The LAB-treated silage increased IVDMD but decreased CH4 production. Thus, the addition of L. casei TH14 inoculant could improve lactic acid fermentation, in vitro digestibility, and CH4 mitigation in the FS mixture silages.

Fermentation Quality

This study was carried out to assess the effects of adding Lactobacillus plantarum, molasses or/and ethanol on the fermentation quality, in vitro digestibility and aerobic stability of total mixed ration (TMR) silage, which is well accepted in small-scale dairy farms in Tibet. Total mixed ration were ensiled in laboratory silos (1 L) and treated with (1) no additive (Control), (2) ethanol (E, 25 ml/kg fresh weight (FW)), (3) molasses (M, 30 g/kg FW); (4) Lactobacillus plantarum (L, 106cfu/g FW); (5) ethanol + molasses (EM); and (6) ethanol + Lactobacillus plantarum (EL). After 45 days of ensiling, six silos per treatment were opened for the fermentation quality and in vitro digestibility analyses, whereas 18 silos were used for the aerobic stability test for the following 9 days. All TMR silages were well preserved with dominant lactic acid (LA), low pH and ammonia nitrogen, and negligible propionic and butyric acid. The L and EL silages had the lowest pH and highest LA concentrations. The addition of ethanol did not inhibit silage fermentation as there were no significant differences for the pH, LA, acetic acid, negligible propionic acid or ammonia nitrogen content, lactic acid bacteria and yeast counts between Control and the E silage. During the aerobic stability test, pH increased by 1.39, 1.67, 1.69 and 0.74 for the Control, M, L and EM silages, but only 0.40 and 0.34 for E and EL silages, respectively. Upon exposure to air, the LA concentration in the L silage was evidently (P < 0.05) decreased, whereas LA concentration in the EL silage remained the highest value after the third day of aerobic exposure. Mean populations of aerobic bacteria and yeast in the E and EL silages were lower (P < 0.05) than those of the Control. These findings suggested that L. plantarum is effective in improving fermentation quality of TMR silages. Although the addition of ethanol in our study did not depress the fermentation of the TMR silages, it showed potential to inhibit the aerobic spoilage of TMR silages, either alone or in combination with the L. plantarum. It is concluded that L. plantarum combined with ethanol not only ensures better fermentation but also could improve aerobic stability.

Cornus Mas

Cornus mas was used in this study as a rich source of health-promoting bioactives. The cornelian cherries were used to extract the polyphenols and anthocyanins. The chromatographic profile of the Cornus mas fruit extract revealed the presence of several anthocyanins, mainly delphinidin, cyanidin and pelargonidin glycosides. The extract was co-microencapsulated with Lactobacillus casei ssp. paracasei in a unique combination of whey protein isolates, inulin and chitosan by freeze-drying, with an encapsulation efficiency of 89.16 ± 1.23% for anthocyanins and 80.33 ± 0.44% for lactic acid bacteria. The pink-red colored powder showed a total anthocyanins content of 19.86 ± 1.18 mg cyanidin-3-glucoside/g dry weight (DW), yielding an antioxidant activity of 54.43 ± 0.73 mMol Trolox/g DW. The viable cells were 9.39 × 109 colony forming units (CFU)/g DW. The confocal microscopy analysis revealed the microencapsulated powder as a complex one, with several large formations containing smaller aggregates, consisting of the lactic acid bacteria cells, the cornelian cherries’ bioactive compounds and the biopolymers. The powder was tested for stability over 90 days, showing a decrease of 50% in anthocyanins and 37% in flavonoids content, with no significant changes in antioxidant activity and CFU. The powder showed a significant inhibitory effect against the α-amylase of 89.72 ± 1.35% and of 24.13 ± 0.01% for α-glucosidase. In vitro digestibility studies showed a significant release of anthocyanins in gastric juice, followed by a decrease in intestinal simulated conditions. The functional properties of the powder were tested by addition into a yogurt, highlighting a higher and more stable antioxidant activity at storage when compared to the control.
