“…GP 24 from leaf was inversely proportional to lignin and EE concentrations. Interestingly GP 24 values in the present study (12.0-36.8 mL/200 mg DM) were lower than those reported by Kara (2019) for fibrous feedstuffs (36.7-75.8 mL/200 mg DM) determined using rumen fluid of Damascus goats. Negative values for gas production from the immediately fermented fraction (a) (as low as -21.5 mL/200 mg DM), recorded in this study, are in accordance with those reported (from -3.0 to -1.7 mL/200 mg DM) in shrubs by Selmi et al (2010) in north Tunisia.…”

“…While lignin concentration tended to vary with seasons with lower values in spring, differences between seasons were not great and were unlikely to affect intake and nutritive value of most species in all seasons. Lignin concentrations in the current study (range 2.2 % for C. pallida to 13.9 % for G. angustifolium) range from low to high according to Anele et al (2009) and Kara (2019). Further studies should examine biomass production of available forage to assess the potential of these feed sources for maintenance of small ruminants in rangelands of northeastern Mexico.…”

“…Although differences were seen in nutrient concentrations in leaves of C. pallida, C. suaveolens, F. angustifolia, G. angustifolium and P. aculeata, seasonal mean CP concentrations in leaf samples ranged from 18.8 to 26.0 %, which far exceeds the requirements of 7-10 % (NRC 2007) for maintenance and growth of whitetailed deer, adult range goats and sheep, with C. pallida providing the highest CP concentration. Ramı ŕez et al (2000) and Domínguez-Gómez et al (2011) Kara (2019). However, it would provide adequate energy to support small ruminants.…”

This study aimed to determine seasonal chemical composition, metabolizable energy (ME) concentration, in vitro gas production patterns, in vitro organic matter digestibility (IVOMD) and in vitro true organic matter digestibility (IVTOMD) of foliage from 5 native shrub species (Celtis pallida, Croton suaveolens, Forestiera angustifolia, Guaiacum angustifolium and Parkinsonia aculeata) growing in semi-arid areas of northeastern Mexico between July 2018 and June 2019 at 2 research sites. Crude protein (CP) concentrations (>13.2% DM) found in leaf material should meet or exceed the requirements for maintenance of small ruminants; C. pallida provided the highest CP% (20.8‒29.3%). While CP% varied with season and site, species had a greater effect than either of those factors overall. ME concentrations ranged between 1.2 and 2.0 Mcal/kg DM. Neutral detergent fiber and acid detergent fiber concentrations ranged from 29.8 to 51.7% DM and 9.8 to 33.0% DM, respectively. Data obtained for IVOMD (34.5‒58.8%) and IVTOMD (64.1‒88.7%) demonstrate the high nutritive potential of leaf of browse species under study, especially C. pallida, as useful feed supplements for small ruminants in the semi-arid region of northeastern Mexico. Further studies could examine DM yields of browse from the various species, acceptance by small ruminants and their sustainability under regular defoliation under grazing.

“…It is known that improvements in animal performance from feeding inoculated silage are difficult to explain (Muck et al, 2018), therefore, in this study, the greater production could be explained by the better content of NDF, ME and rumen fermentation in treated silage group and probably by the inhibition of detrimental microbes and toxin production (Ellis et al, 2016), interaction of LAB with rumen microbes, and alteration of rumen fermentation (Weinberg et al, 2003). The greater NDF concentration of SB+additive is not necessarily related to poorer animal performance, as NDF of sugar-beet (Michel et al, 1988) and therefore highly digestible in the rumen (Kara, 2019). Loucka (2012) observed that sugar beet pulp silages without additives have a more of alcoholic fermentation and with higher proteolysis, factors that can negatively affect milk production.…”

Sugar-beet (Beta vulgaris L. subsp. vulgaris) pulp is a valuable by-product from the manufacture of beet sugar fresh which is normally preserved in the form of silage. The aim of the present research was to evaluate the effect of adding a homofermentative lactic acid bacteria silage additive during the ensiling period on fermentation and quality of sugar-beet (SB) pulp silage and the animal performance of dairy cows given restricted daily access to pasture. Twelve Holstein × Friesian crossbred cows were assigned to two groups according to milk yield, body weight, days in milk, parity and body condition score. Groups were randomly allocated to two treatments: silage of SB pulp without additive (control diet, SB) and silage of SB pulp with additive (SB+additive). The experiment was carried out in two periods of 28 d each. Once finished each period, cows were crossed for treatments. Chemical composition of SB silage was modified by the additive: Neutral detergent fiber (41.8% vs. 45.7% DM) and metabolizable energy (2.54 vs. 2.55 Mcal kg -1 DM) were greater and butyrate lower (0.34 vs. 4.10 mmol L -1 ) for SB+additive compared with SB. However, milk production (24.6 and 25.2 kg d -1 ) and composition were not affected (P > 0.05) by treatments. Similarly, rumen volatile fatty acids were similar between treatments. In conclusion, the use of homofermentative lactic acid additive on SB silage modified the chemical composition of silage and reduced the pasture intake, however, no changes in milk production and composition were detected.

“…The production of SCFA which was based on carbohydrate fermentation was closely related with in vitro gas production from different class of feed (Blummel et al, 1990). The molarity of ruminal short chain fatty acid was positively correlated with ruminal digestibility of feed (Kara, 2019). Availability of quality of forage to livestock is the main influencing factor for animal performance (Lazzarini et al, 2009;Woolley et al, 2009).…”

The study was carried out to evaluate the forage yields, nutritive values and in vitro fermentation parameters of herbaceous legumes. Five varieties of introduced herbaceous legumes; Stylosanthes guianensis cv. Ubon stylo, Macrotyloma axillare cv. Archer, Centrosema brasilianum cv. Ooloo, Stylosanthes guianensis cv. Stylo 184 and Macroptilum bracteatum cv. Cadarga were evaluated at the research farm, University of Veterinary Science, Yezin, Myanmar. No fertilizer and no irrigation were applied for cultivation to test drought resistance. Dry forage yield, nutritive values and gas production at four harvesting times were measured with 4×5 factorial arrangement (5 legumes and 4 harvesting time) in randomized complete block design. There was no interaction between legumes and harvesting time on forage yield, nutritive values and fermentation parameters but they were affected by the main effects of legume types and harvesting time. Among the legume forages, the highest dry forage yields were found in Ooloo, Ubon stylo, and Stylo 184, and followed by the DM yield of Archer and Cadarga. The DM yield of the second harvest was significantly higher (p<0.05) than those of the first, third and fourth harvest which were not significantly different from each other. As a chemical composition, the DM content of Archer was lower (p<0.05) than those of other varieties. Among the legumes forages, the lower CP content was found in Cadarga. The higher NDF was observed in Ooloo. Ooloo, Ubon stylo and Cadarga showed higher ADF in comparison with the other two varieties. Among the harvesting time, the lowest DM content was found at the first harvest. The highest CP content was found at third harvest. The NDF content was not significantly different. The lowest ADF content was found in fourth harvest. According to the dry forage yield, Ubon stylo and Ooloo had the highest dry forage yield and in term of nutritive values, Stylo 184 and Archer had higher nutritive values. As the main effect of forages, Stylo 184 and Archer had higher gas production in comparison with the other varieties. As the main effect of harvesting time, the fourth harvest had the highest gas production in comparison with other harvesting time. It could be better for cultivation by application of fertilizer and irrigation to get more forage yield and quality.
