The Government

Armenia is a typical highland country with an average altitude of 1800 m. More than half of its territory is occupied by natural pastures and hay producing areas which form an important source of feed material for animal husbandry. However, in recent years the country has been experiencing an acute shortage of feed materials and as a result the total number of livestock and animal derived products has drastically dropped. During the transition to a market economy the government has been unable to import additional forage materials, therefore there is a need to utilise local resources more rationally. Limited studies of the nutritive value of Armenia’s forage plants has been carried out. Moreover, in previous studies the fundamental criteria for measuring forage quality has been largely limited to an assessment of crude protein (CP), total ash (TA), crude fat (CF), nitrogen-free extractable substances (NFS) and crude cellulose (CC) contents. Only recently have studies been undertaken to assess gross energy (GE) and in-vitro digestible organic matter (OM) in the dry matter (DOMD) contents, and OM digestibility (OMD) and digestible energy (DE) value of OM. The objective of this work was to summarize the published studies on chemical composition and to discuss the results of recent measurements of energy value and in-vitro digestibility of native forages in Armenia in order to facilitate the selection and utilisation of high quality forages by farmers.

In this study, Chinese yam starch-water suspension (8%) were subjected to high-pressure homogenization (HPH) at 100 MPa for increasing cycle numbers, and its effect of on the physicochemical properties of the starch was investigated. Results of the polarizing microscope observations showed that the starch granules were disrupted (i.e. greater breakdown value) after HPH treatment, followed by a decrease in cross polarization. After three HPH cycles, the crystallinity of starch decreased, while the crystal type remained unaltered. Meanwhile, the contents of rapidly digestible starch and slowly digestible starch were increased. On the contrary, resistant starch content was decreased. Our results indicate that HPH treatment resulted in reduction of starch crystallinity and increase of starch digestibility.

Abstract Background The study highlighted the potential of three common and under-utilized tropical leguminous seeds (Tomentosa nilotica, Dioclea reflexa and Monodora myristica) to be used as supplementary feed to ruminant livestock. These seeds (their plants inclusive) are valuable sources of food and medicine for the prevention of illness and maintenance of human health. The medicinal properties of these seeds include antimicrobial, anti-inflammatory, anti-oxidant and immuno-stimulant. Trypsin inhibitors, which are common anti-nutritional factors in legumes and for monogastric animals, do not exert adverse effects in ruminants because they are degraded in the rumen. Hence, the crux of this study is to examine the effect of processing methods on the nutritional composition (proximate, fibre fractions, minerals, anti-nutrients) and in vitro digestibility of Tomentosa nilotica, Dioclea reflexa and Monodora myristica seeds and their suitability as feedstuff (protein sources) in small ruminant feed, particularly during off-season. Results From the results, raw Tomentosa nilotica and Monodora myristica have the highest crude protein (30.35% CP) and fat (22.40% EE), respectively. It is noteworthy that roasting best improve the mineral and significantly reduce the anti-nutrients observed in this study better compared to boiling and soaking methods. The highest organic matter digestibility, short-chain fatty acids, metabolizable energy and in vitro dry matter digestibility values were obtained in Dioclea reflexa compared to other test seeds. Roasting best improved the nutritive values, while Dioclea reflexa seed was rated highest for all the nutritional attributes and in vitro digestibility. Conclusions Dioclea reflexa could be incorporated in ruminants’ diet as protein source, particularly during the off-season, for improved ruminant production in Nigeria. However, in vivo study is therefore recommended to validate this report.

Protein-based biodegradable packaging films are of environmental significance. The effect of oxidized ferulic acid (OFA)/tannic acid (OTA) on the crosslinking and film-forming properties of whey protein isolate (WPI) was investigated. Both of the oxidized acids induced protein oxidation and promoted WPI crosslinking through the actions of quinone carbonyl and protein sulfhydryl, and amino groups. OTA enhanced the tensile strength (from 4.5 MPa to max 6.7 MPa) and stiffness (from 215 MPa to max 376 MPa) of the WPI film, whereas OFA significantly increased the elongation at break. The water absorption capability and heat resistance of the films were greatly improved by the addition of OTA. Due to the original color of OTA, the incorporation of OTA significantly reduced light transmittance of the WPI film (λ 200–600 nm) as well as the transparency, whereas no significant changes were induced by the OFA treatment. Higher concentrations of OTA reduced the in vitro digestibility of the WPI film, while the addition of OFA had no significant effect. Overall, these two oxidized polyphenols promoted the crosslinking of WPI and modified the film properties, with OTA showing an overall stronger efficacy than OFA due to more functional groups available.

Abstract A study was conducted to determine the effects of the period of predigesting whole stillage (WS; slurry material that is dried into DDGS) with multi-enzyme and composition of the multi-enzyme on porcine in vitro digestibility of dry matter (IVDDM) of the WS. Four samples of whole stillage from 4 different sources were freeze-dried and divided into 13 subsamples to give 52 sub-samples. Thirteen treatments were applied to the 48 sub-samples within source. The treatments were undigested WS (control); or pre-digested with 1 of 3 multi-enzymes (MTE1, MTE2, and MTE3) at 55 °C for 6, 12, 18 or 24 h in 3 × 4 factorial arrangement. The MTE1 contained xylanase, β-glucanase, cellulase, mannanase, protease, and amylase; MTE2 contained xylanase, α-galactosidase, and cellulase; and MTE3 contained xylanase, cellulase, β-glucanase, and mannanase. The 52 subsamples were subjected to porcine in vitro digestion. The IVDDM of untreated WS was 73.3%. The IVDDM increased (P< 0.05) with an increase in the predigestion period. However, a rise in the predigestion period from 0 to 12 h resulted in greater (P< 0.05) response in mean IVDDM than an increment in the predigestion period from 12 to 24 h (11 vs. 0.83 percentage points). Predigestion period and multi-enzyme type interacted on IVDDM such that the improvement in IVDDM between 0 and 12 hours of predigestion differed (P< 0.05) among the 3 multi-enzyme types (13.3, 11.1, and 8.5 percentage points for MTE3, MTE2, and MTE1, respectively). The LS means by multi-enzyme treatment were modeled and resulted in unparallel curves (P< 0.05). The estimated maximum response of IVDDM for MTE1, MTE2 and MTE 3 were 82.4%, 84.7% and 87.1% at 15.8, 13 and 13.1 hours, respectively. In conclusion, the optimal time of predigestion of WS with multi-enzymes (with regard to improvement in its IVDDM) was approximately 14 h.
