Cowpea Varieties

ABSTRACT Cowpea is an herbaceous legume susceptible to several insects and diseases; and the beetle Callosobruchus maculatus is the main pest causing direct losses in the production of this crop. The objective of this work was to assess the physical and bromatological characteristics of beans of cowpea varieties (Bico-de-Ouro, BRS-Novaera, BRS-Guariba and BRS-Tumucumaque) preferred by C. maculatus. Adults of C. maculatus were obtained from a storage unit of cowpea beans. The physical and bromatological characteristics and attractiveness of cowpea beans to insects were evaluated in laboratory. The preferences for oviposition with no choice and attraction to cowpea beans by C. maculatus are not related to the high protein content or physical characteristics of the bean seed coat (thickness and fiber content), since the insects were more attracted to beans of the variety Bico-de-Ouro, which had low crude protein content, the thickest seed coat and high NDF content.

Abstract Feed is one of the factors determines the success of a fish farm. Feed-quality feed stuffs that require high quality also, which still rely on imports, especially fish meal and soybean oilcake. Effort to reduce dependence on import of feed stuff is searching for alternative feed stuffs that the quality is quite good, cheap, easily obtained and can reduce cost of production. One of the feed stuff as an alternative source of animal protein feed that need to be examined is the prawn waste. Prawn waste meal enough potential to be used as fish feed with a crude protein content 45.29% and 17.59% crude fiber was alternative feed stuff for fish meal. The usage of prawn waste as a feed stuff should be through the handling and processing to further improve the nutrient value of waste. Prawn waste processing in this research consists of two ways, that is waste cooking prawn on the high pressure (100 kpa), and conducted fermentation by using probiotic. The existence of microorganisms activity during the fermentation process will cause changes of feed stuffs either through physically and chemicals. Probiotic is a microbe colony that is rich in celulolytic, lignolytic and proteolytic bacteria. The aim of this research is to know the influence probiotic on the prawn waste cooked with high pressure to increase the protein content and to decrease the crude fiber content. Method as used in the research is experimental method. Experiment design that used at research is Completely Randomized Design with 4 treatments and replicates 5 times. To get the data is conducted procsimat analysis on the crude protein content and crude fibers from each experimental unit. That result data analyzed with the Analysis of Varian continued with Duncan’s Multiple Range Test. The results of research is known that dosaged probiotic at process of prawn waste cooked fermentation not different to crude protein contents of the waste cook fermented prawn. Crude fiber content of the waste cook fermented prawn using probiotik (P1, P2, P3) has decreased if compared with waste cooking fermented prawn without using probiotic (P0)

Metabolisable Energy

A study determined the effects of differing rates of nitrogen fertiliser [0 (N0), 25 (N1), 50 (N2) and 75�kg N/ha (N3)] during late autumn (T1) and mid- (T2) and late (T3) winter on the nutritive characteristics of perennial ryegrass over a 28-day period after each application. All nitrogen applications were made to pastures with a post-grazed residual mass (dry matter) of 1400 kg/ha. Changes in metabolisable energy followed similar patterns for all treatments within a given period. Metabolisable energy was highest in T1, ranging from 11.8 to 13.1 MJ/kg dry matter, followed by T2 (11.5-12.3 MJ/kg dry matter) and T3 (10.6-11.5 MJ/kg dry matter). Changes in crude protein for all treatments at each application time were similar, irrespective of rate of nitrogen application. At the commencement of treatment application times, the existing crude protein content (%DM) was highest in N3 (T1�19, T2 23, T3 22), followed by N2 (T1 18, T2 21, T3 21), N1 (T1 17, T2 20, T3 20) and N0 (T1 16, T2 17, T3 18). During both T1 and T2, neutral detergent fibre content decreased by 4 percentage units and increased by a similar amount during T3. Generally, neutral detergent fibre content (%DM) was highest during T3 (53-58%), followed by T2 (45-54%) and T1 (43-49%). Water-soluble carbohydrate content (%DM) increased during all treatment periods with the highest level observed during T1 (18-31%) followed by T2 (3-14%) and T3 (1-6%). Nitrate content (measured as nitrate-nitrogen) decreased throughout T1, primarily due to dry conditions, while during T2, levels for N3 and N2 were significantly (P<0.05) higher than for N1 and N0 following nitrogen fertiliser application. During T3, nitrate content increased for all treatments throughout the 28-day period, with highest nitrate levels being observed during T3. The effect of applied nitrogen on mineral content was variable within and across treatment periods. The study indicates that nitrogen fertiliser did not affect metabolisable (apart from N3 elevating metabolisable energy during T3), neutral detergent fibre or water-soluble carbohydrate contents of perennial ryegrass during the 28 days after nitrogen application, but increased crude protein content. Also, nitrogen fertiliser elevated nitrate content in perennial ryegrass. While the elevated nitrate content observed may result in subclinical effects, these levels are not considered fatal for dairy cows. Crude protein content was generally above 20% of dry matter throughout the study and close to 30% of dry matter for short periods during T2. Minimising the effect of excess nitrogen ingested by the grazing animal may require appropriate supplementation of low crude protein containing feeds such as cereal grains. It is argued that the effects of rain and temperature, which impact on soil nitrogen mineralisation, may have a greater influence on perennial ryegrass nitrate content than nitrogen fertiliser.

The study was conducted to determine forage quality criteria of Salvia multicaulis VAHL. species collected from different locations of Southeastern Anatolia Region of Turkey in 2018. Results of statistical analysis of the study data revealed that there were significant differences among the locations for all of the investigated traits. Additionally, among the locations the investigated traits were changed as following; dry matter content (DM) 88.66-91.58%, crude protein content (CP) 16.47-25.37%, insoluble protein content in acid detergent (ADP) 0.8%-1.10%, acid detergent fiber content (ADF) 22.08-29.54%, neutral detergent fiber content (NDF) 29.71-%43.85%, calcium (Ca) content 1.22-1.82%, phosphor (P) content 0.23-0,40%, Ca:P ratio 3.05-6.87, potassium (K) content 1.20-2.58%, magnesium (Mg) content 0.28-0.46% and K/(Ca+Mg) ratio 0.55-1.44. Results of the study revealed that dry forage of Salvia multicaulis species is both rich in terms of crude protein content and having a high digestibility level and its macro minerals content and K/(Ca+Mg) ratio to be sufficient for animal feeding. However, due to its too high level Ca:P ratio than critical top level (2:1), it is important to be careful against the risk of poisoning of animals when the forages of this species are used in animal feeding. Hence, additional research is required to determine the harmful effect of the species on the livestock health.

Low Protein

The effectiveness of cattle breeding is mostly determined Forage base. Currently, cattle productivity in the Russian Federation is increasing, and this requires a more careful approach to assessing the quality of feed. This primarily applies to such types of feed like hay, silage, haylage, which make up 60-85% in the average daily diet of livestock. The nutritional value of these types of feed depends mostly on the content and ratio of crude protein and crude fiber in perennial grasses when they are harvested. In the early phases of plant development, crude protein predominates in its composition, and the fiber content is insufficient. Therefore, mowing perennial grasses in these terms is irrational. With the growth and development of the plant, its transition to the heading stage, the crude protein content decreases with increasing fiber content. Harvesting perennial grasses at a time when they contain a large amount of fiber and low protein is also irrational since the low protein content in feed does not contribute to the growth of animal productivity. The optimum time for harvesting herbs is considered to be the time when the crude protein content is 14-16%, and crude fiber – 26-28%. Determination the content of these elements is a rather laborious and expensive process, the analysis lasts about three days. Only large agricultural enterprises can afford to carry out such analyses. At the same time, today, there are technologies for remote sensing of crops, which in this case can be carried out using unmanned aerial vehicles (UAVs). Currently, with their help, the nitrogen content in plants is determined. The authors of this paper propose a digital technique for remote determination of crude fiber and crude protein, which determines the optimal timing of the harvesting herbs.

The objective of this study was to evaluate the chemical composition and protein and carbohydrate fractions in three forage species (Andropogon gayanus Kunth, Cenchrus ciliares L. and Panicum maximun x Panicum infestum) at four cutting ages: 21, 35, 49 and 63 days. Experiments were carried out at the Federal Institute of Education Science and Technology of Rio Grande do Norte - IFRN, located in the municipality of Apodi- RN, Potiguar West Meso-region. Materials collected in the field were analyzed in the Laboratory of Animal Nutrition (LANA), Federal Rural Semiarid University (UFERSA), Campus Mossoró, RN. Samples were processed, phenated, and analyzed. The analysis conducted included fractionation of nitrogen compounds and carbohydrates and chemical composition (dry matter, mineral matter, crude protein, lipids and fibers) was determined. The forages evaluated showed decreasing crude protein content with increasing cutting age, ranging between 14.9 and 6.2%. Andropogon grass showed the highest crude protein content. The fiber content increased with age. Fiber consisted of 62.4%–70.0% NDF and 30.07%–33.03% ADF. Highest fiber content was recorded for Massai grass, in which case, these two component species showed the highest fractions of intermediate degradation protein (B2), while Andropogon and Buffel Capins showed higher fractions of non-fibrous carbohydrates (A and B1). An increase in the concentration of cell-wall material in the detriment of the cellular content with increasing plant age was observed in the fodder studied. We also observed an increase in the indigestible fraction (C) of proteins and carbohydrates in the species studied.

In the dryland areas of southern Australia, summer-active forage crops have been traditionally grown to provide additional home-grown feed during a period when pasture is often in short supply. Dry matter (DM) yields are often variable and the use of nitrogen (N) fertiliser is considered a viable option to increase such yields. The effect of applying N fertiliser to the summer-active species, forage brassica cv. Hunter (Brassica campestris L. × Brassica napus L.), forage brassica cv. Winfred (Brassica napus L.), turnips (Brassica rapa L. cv. Barkant), chicory (Chichorium intybus L. cv. Grouse), plantain (Plantago lanceolata L. cv. Tonic), sorghum sudangrass hybrid cv. Sweet Jumbo [Sorghum bicolour (L.) Moench × Sorghum sudanese (Piper) Stapf.], millet (Echinochloa utilis Ohwi & Yabuno) and a mixture of Winfred and millet (1 : 5) over two summer periods were measured. N was applied at 0, 40, 80, 120, 160 and 200 kg N/ha with half of the N being applied ~5–6 weeks after sowing for all crops and the remainder immediately following the first grazing of regrowth crops and at 9 weeks after sowing for turnips. DM yield responses to applied N were variable, with increases only being observed in the first year. For the regrowth forages (all forages except turnips), the DM yield increase occurred during the second growth period and reflects higher than average rainfall during that period. The crude protein content of all forages generally increased with increasing N application in both years, with the highest response being 0.14% per kg N applied. In contrast, the water-soluble carbohydrate content of forages decreased with N application. The results from this study indicate that the effect of applying N fertiliser to summer forages is limited by available moisture and subsequent active growth of the forage. Where there is adequate moisture, N application can improve DM yield and also the crude protein content of most summer forages. Application of N to summer forages should be seen as a tactical decision based on available soil moisture and active plant growth to ensure N uptake and subsequent DM accumulation.
