Forage Yields

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.

Forage Yields

Annual grasses and legumes offer potential as forages in the northern Great Plains region of the USA during late summer when perennial cool-season grass pastures are unproductive. The objective of this study was to evaluate the forage yield, in vitro digestible dry matter (IVDDM), and crude protein concentration of four annual species planted in May, June, and July at two South Dakota locations in 1989 and 1990. The species evaluated were cowpea (Vigna unguiculata (L.) Walp.), mungbean (Vigna radiata (L.) Wilczek), soybean (Glycine max (L.) Merr.), and Siberian foxtail millet (Setaria italica (L.) Beauv.). In 1989 cowpea, soybean, and millet produced similar yields at Highmore when planted in May, whereas in 1990 soybean had the highest forage yield of 8.3 t ha−1. Forage yields for the July planting were lower than those of the May planting, except for mungbean grown at Highmore in 1989 where the July planting produced 2.2 t ha−1 more forage than the May planting. Cowpea had significantly greater IVDDM than the other species for all three planting dates at Beresford in 1989, whereas at Highmore IVDDM for cowpea was not greater than that of mungbean for the May and June planting dates. Cowpea had the greatest crude protein concentration for all planting dates at Highmore in 1989, the greatest crude protein concentration for May and June planting dates at Beresford, and similar crude protein concentration to soybean for the July planting date. Millet, with the exception of the May planting at Highmore in 1990, consistently had lower IVDDM and crude protein concentrations than all three legumes each year at each location. The highest soybean forage yields at each location were always obtained from the May plantings. Cowpea forage yields were highest for the May planting at Highmore in 1989 and the June planting in 1990. Since cowpea often had higher forage yields, IVDDM, and crude protein concentrations than the other species it appears to be a viable alternative forage crop for this region.Key words: Annual forage legumes, millet, yield, quality

Paraquat, cultivation, or cultivation plus oat interseeding (56 or 84 kg/ha) into established alfalfa were evaluated for their effect on weeds, forage yield, and forage composition at Santa Ynez, Lancaster, and Stockton, CA. Treatments were applied during the winter to dormant alfalfa and evaluated in the subsequent harvest season. Paraquat reduced first harvest total forage yields 20 to 33% compared to untreated alfalfa, whereas oat interseeding increased total forage yields 16 to 36%. Cultivation reduced total forage yield in the first cutting by 26% at Lancaster but did not affect forage yield at the other sites. Total or component forage yields were not affected by any treatment in the second and subsequent harvests, with the exception of weeds. Paraquat reduced weed biomass in the first harvest by 45 and 49% at Lancaster and Stockton. Oat interseeding reduced first harvest weed biomass by 80% at Lancaster but did not affect weed biomass at Stockton or Santa Ynez. Oat interseeding or paraquat treatment reduced weed biomass in the second harvest at Stockton, but did not affect weeds in any other harvest at any of the sites. Oat interseeding was comparable to paraquat treatment for weed control, with the advantage of also increasing first harvest forage yield.

The effects of weed control measures in established alfalfa (Medicago sativaL.) on forage yield and quality were investigated at three sites with varying alfalfa densities and weed populations. Herbicide treatments were 0.56 and 1.12 kg/ha metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] applied in fall or spring, respectively, 1.68 kg/ha pronamide [3,5-dichloro (N-1,1-dimethyl-2-propynyl)benzamide] applied in fall, and combinations of these treatments. First-harvest forage yields (weeds plus alfalfa) were either reduced or unchanged by herbicide treatments. Total forage yield was not altered by the herbicide treatments, but first-harvest and total alfalfa yield as well as first-harvest forage protein content were increased by several treatments, depending on stand density and weed pressure. Little effect was observed on in vitro digestible dry matter or acid detergent fiber content.

Abstract Background Treatment of a child who has an anxiety disorder usually begins with the question of which treatment to start first, medication or psychotherapy. Both have strong empirical support, but few studies have compared their effectiveness head-to-head, and none has investigated what to do if the treatment tried first isn’t working well—whether to optimize the treatment already begun or to add the other treatment. Methods This is a single-blind Sequential Multiple Assignment Randomized Trial (SMART) of 24 weeks duration with two levels of randomization, one in each of two 12-week stages. In Stage 1, children will be randomized to fluoxetine or Coping Cat Cognitive Behavioral Therapy (CBT). In Stage 2, remitters will continue maintenance-level therapy with the single-modality treatment received in Stage 1. Non-remitters during the first 12 weeks of treatment will be randomized to either [1] optimization of their Stage 1 treatment, or [2] optimization of Stage 1 treatment and addition of the other intervention. After the 24-week trial, we will follow participants during open, naturalistic treatment to assess the durability of study treatment effects. Patients, 8–17 years of age who are diagnosed with an anxiety disorder, will be recruited and treated within 9 large clinical sites throughout greater Los Angeles. They will be predominantly underserved, ethnic minorities. The primary outcome measure will be the self-report score on the 41-item youth SCARED (Screen for Child Anxiety Related Disorders). An intent-to-treat analysis will compare youth randomized to fluoxetine first versus those randomized to CBT first (“Main Effect 1”). Then, among Stage 1 non-remitters, we will compare non-remitters randomized to optimization of their Stage 1 monotherapy versus non-remitters randomized to combination treatment (“Main Effect 2”). The interaction of these main effects will assess whether one of the 4 treatment sequences (CBT➔CBT; CBT➔med; med➔med; med➔CBT) in non-remitters is significantly better or worse than predicted from main effects alone. Discussion Findings from this SMART study will identify treatment sequences that optimize outcomes in ethnically diverse pediatric patients from underserved low- and middle-income households who have anxiety disorders. Trial registration This protocol, version 1.0, was registered in ClinicalTrials.gov on February 17, 2021 with Identifier: NCT04760275.

Cassava Residue

The feeding value of replacing concentrate with cassava (Manihot esculenta) residue in the feed of Holstein cows was confirmed using an in vitro gas test. The treatments consisted of 0% (control, CON), 5%, 10%, 15%, 20%, 25%, and 30% inclusion of cassava residue in fermentation culture medium composed of buffer solution (50 mL) and filtrated rumen fluid (25 mL). The parameters analyzed included the kinetics of gas production and fermentation indexes. Forty-eight hours later, there were no significant differences on in vitro dry matter disappearance (IVDMD), pH, and microbial crude protein (MCP) content among treatments (p > 0.05). However, the “cumulative gas production at 48 h” (GP48), the “asymptotic gas production” (A), and the “maximum gas production rate” (RmaxG) all increased linearly or quadratically (p < 0.01). The GP48 was significantly higher in the 25% treatment compared to the other treatments, except for the 30% (p < 0.01). The A was significantly larger in the 25% treatment compared to the other treatments, except for the 20% and 30% (p < 0.01). The RmaxG was distinctly larger in the 25% treatment compared to other treatments (p < 0.01); moreover, the “time at which RmaxG is reached” (TRmaxG) and the “time at which the maximum rate of substrate degradation is reached” (TRmaxS) were significantly higher in the 25% treatment than the CON, 20%, and 30% treatments (p < 0.01). Additionally, the content of ammonia-N (NH3-N) in all treatments showed linearly and quadratically decreases (p < 0.01), whereas total volatile fatty acid (VFA), iso-butyrate, butyrate, and iso-valerate contents changed quadratically (p = 0.02, p = 0.05, p = 0.01, and p = 0.02, respectively); all of these values peaked in the 25% treatment. In summary, the 25% treatment was associated with more in vitro gas and VFA production, indicating that this cassava residue inclusion level may be used to replace concentrate in the feed of Holstein cows. However, these results need to be verified in vivo.

Abstract This investigation involves study of independent variable that influences the Young modulus of thermoplastic mango starch (TPS) as dependent response factor. The experiment was design using the Taguchi orthogonal technique with four independent variables; plasticiser type; glycerol (G), and Triethanolamine-(TEA) (T), percentage plasticiser (40 and 120 %), percentage carboxymethyl cellulose-CMC (10 and 50 %), and concentration of HCl (0.05 and 0.15 M). The result of the main effect plots for mean indicated that the gTPS-CMC1 with 268.85a MPa is a better outcome compared to gTPS-CMC3 with 280.31a MPa, since no significance difference was observed due to less composition requirement of CMC for gTPS–CMC1, making it more cost effective to produced with better optimum conditions. The interaction plot of the independent variables showed that for plasticiser types; when glycerol (G) was utilised a higher young modulus is observed than TEA (T) and only interacts with TEA (T) at 0.015 M HCl; 10 % CMC gives a higher response compared to 50 % CMC and showed no interaction even as the other independent variables fluctuates, and similar effect was observed for percentage plasticiser. Study concluded that the predicted mean (young modulus) is substantially consistent with the experimental observation (R2 = 0.6283).

The data for a total of seventeen digestion trials with sheep receiving grasses, legumes, two mixtures of these, and low protein synthetic mixtures as sole rations are reported. The biological values for the proteins of the cow pea increase as the plant passes from the just before blooming stage through the full bloom to the full pod stages of maturities. The biological values for proteins are also higher for the grasses than for the legumes when fed singly. The grasses studied during the last three years can be arranged in the following order of decreasing net-protein values: Guinea, Merker, Para, Elephant, Guatemala and Yaraguá. The nutritive ratio for the Yaraguá grass is very wide due to the low digestible protein, as is shown in the data. Alfalfa hay yields more total digestible nutrients, more crude fiber and more ether soluble extract than any of the other legumes studied. The percentage intake of protein stored is greater with a mixture of Merker grass and pigeon pea than when the grass is fed alone. The vitamin A activities of some grasses and legumes are reported.

SUMMARYModifying the extent of fatty acid (FA) biohydrogenation (BH) in the rumen through diet formulation is an effective strategy for changing the content of unsaturated FAs (USFAs) in meat. The present study investigated the effects of different sources of forage in high-concentrate diets on intake, digestibility, rumen fermentation, ruminal BH, duodenal flow of FAs and rumen microbiota in Nellore steers. Intake of neutral detergent fibre (NDF) was higher in animals fed with maize silage (MS) than in those fed with sugar cane (SC) and sugar cane bagasse (SB). Higher digestibility of dry matter and NDF was found in animals fed with MS than in those fed with the other diets. In addition, higher crude protein digestibility was observed in animals fed with sugar cane bagasse than in those fed with SC. Non-fibre carbohydrate (NFC) digestibility was higher in animals fed with sugar cane than in those fed with the other diets. Intake of total and individual FAs such as C18 : 1cis-9, C18 : 2, and C18 : 3 was similar between animals fed with MS and SB, but decreased in animals fed with SC. Diets containing MS and SB showed higher total digestibility of saturated FAs (SFAs) and USFAs, respectively and total FAs and ruminal BH of C18 : 1 and USFA. Intestinal digestibility of overall FAs did not differ among treatments, except for C18 : 3, which increased in animals fed with SC and SB. The profile of FAs in duodenal digesta and faecal outputs did not differ among treatments. However, the flow of NDF was higher in animals fed with SC than in those fed with MS and SB. Animals fed with SB showed higher values of pH than those fed with MS and SC. Animals fed with SC showed lower values of ammonia-nitrogen. Protozoan counts were only influenced by diet for species that belonged to the generaDasytrichaandIsotricha. Populations of fibrolytic bacteria (Ruminococus flavefaciens, Ruminococus albusandFibrobacter succinogenes) were similar among diets. Populations ofSelenomonas ruminantiumincreased 2·5 and 5 times in animals fed with MS when compared with those fed with SC and SB, respectively. The use of MS increased intake and digestibility of NDF, and the use of SC decreased ruminal BH of total USFA without changing the flow of FAs to the duodenum. Thus, different sources of forage in high-concentrate diets do not modify the duodenal flow of USFA or fibrolytic bacteria. This must be taken into account when formulating diets to modulate ruminal upsets without altering intake.

Forage Yields

A mixture of timothy, orchard grass, red clover, alfalfa and Ladino clover was seeded on areas of upland and dikeland soil at Nappan, N.S. Over a 3-year period plots were cut at 3-, 4- and 8-week intervals to stubble heights of [Formula: see text] and 3 inches. Comparisons were made of forage yields and species contribution under the various cutting intensities on the two soils. Forage yield was 20 per cent greater on dikeland and seasonal distribution of forage was better on dikeland than the upland area with which it was compared. Similar responses between treatments were obtained on both dikeland and upland. Timothy contribution fluctuated widely between high spring values and low fall values while orchard grass regularly contributed about 40 per cent of the forage material. Alfalfa contributed reasonably well initially, but failed to persist under more intense clipping, particularly on dikeland. Ladino clover increased in relative value during the 3 years, performing better on upland under more intense clipping.

Agropyron cristatum, Agropyron intermedium, Agropyron riparium, Elymus junceus and Stipa viridula were studied in relation to clipping effects on productivity and longevity. All species, except Elymus junceus, produced progressively less as number of clippings increased. Agropyron intermedium yielded the most forage, especially when harvested only once per season, followed closely by Agropyron cristatum. Crude protein yield was less variable under various frequencies of clipping than forage yield, and differences between species were also smaller. Elymus junceus and Agropyron cristatum displayed the strongest competitive ability, especially under frequent clipping and Stipa viridula the lowest. The amount of root produced varied significantly between species. Agropyron cristatum and Elymus junceus produced the most root and Stipa viridula the least. Fertilizer applied in the fourth and fifth crop years increased the yield by 30 to 200 per cent. It was concluded that Agropyron cristatum and Elymus junceus were about equally persistent under frequent clipping and should be more useful long-term pasture grasses than the other three in dry cold climates.
