The objective of this study was to compare the proximate and mineral compositions of Moringa oleifera and Moringa ovalifolia grown together at Neudamm Experimental Farm in central Namibia. Moringa oleifera is well known for its rich nutritional value and was compared to the nutritional value of M. ovalifolia, a native plant of Namibia and Angola, which is less studied. Namibia being a semi-arid country, many plants in the rangelands are low in nutrients essential for livestock nutrition. This creates the necessity for planting fodder trees like moringa that withstand the harsh climatic conditions and retain their nutritional quality for the production of sustained livestock supplement. Leaves of both Moringa species were harvested with twiglets, shade dried fortnightly and taken to the laboratory where they were ground and passed through 1 mm sieve for proximate and mineral analysis. Statistically, M. oleifera nutrient values were significantly different (P < 0.05) in moisture, ash, crude protein (CP) and crude fiber (CF) from M. ovalifolia, but had no differences in fat, acid detergent fiber (ADF) and neutral detergent fiber (NDF). Also, M. oleifera was significantly different (P < 0.05) from M. ovalifolia in potassium (K), magnesium (Mg), copper (Cu) and zinc (Zn), but there were no differences in calcium (Ca), sodium (Na), phosphorus (P), iron (Fe) and manganese (Mn) values. This implies that both Moringa species have similar quantity of Ca, Na, P, Fe and Mn in their leaf tissues. The almost identical nutrient values of the two Moringa species, suggests that M. ovalifolia could serve as an alternative supplement for livestock since there is a known human-livestock competition for M. oleifera, and since M. ovalifolia is native and well adapted to the harsh environmental conditions of Namibia.

Background: India ranks first in global livestock production and it is an important subsidiary enterprise that support more than 75 per cent of the rural community. But fodder production is not well practiced in our country and animals generally consume naturally grown grasses and shrubs which are of low quality in terms of protein and available energy. Hence, there is an urgent need to look for new fodder resources that are sustainable in nature and cover our fodder deficit. Keeping the above in view, the present study has been proposed to evaluate the predominant tree fodders and shrubs of Southern Kerala as a quality livestock feed. Methods: The study was conducted in College of Agriculture, Vellayani, Thiruvananthapuram during January-September, 2020 to assess the nutritional value of predominant tree fodders and shrubs in Southern Kerala as a quality feed for cattle. Ten different fodder trees and shrubs that locally fed to the cattle viz., Agathi (Sesbania grandiflora), erythrina (Erythrina indica), Drumstick (Moringa oleifera), Coconut (Cocos nucifera), Glyricidia (Glyricidia maculate), Matti (Terminalia elliptica), Subabul (Leucaena leucocephala), Cassava (Manihot esculenta), Banana (Musa acuminate) and Mango (Mangifera indica) were selected and analysed for proximate composition, crude fiber and mineral status. Result: The result revealed that mean values for dry matter, crude protein, crude fiber, ether extract and total ash in tree fodders were 37.07±4.02, 18.52±1.72, 18.56±2.07, 4.68±0.51, 8.72±0.66, respectively. The study also proved that Sesbania grandiflora (Agathi) is nutritionally superior to other tree fodders with high crude protein (25.24%) and lower crude fiber (8.43%) content. The Neutral Detergent Fiber content of fodder tree leaves varied from 17.34- 65.32 per cent and that of Acid Detergent Fiber from 11.10-48.69 per cent. Phosphorus and potassium status of top feeds comes under the range of 0.26-0.93 per cent and 1.0-2.7 per cent respectively. However the highest amount of Calcium as well as magnesium was found in Moringa oleifera (2.75 and 0.60 per cent respectively).

Moringa oleifera Lam., commonly found tree in sub-Himalayan tracts of India, Pakistan, Bangladesh and Afghanistan has a high nutrition value. The leaves, flowers and immature pods of Moringa are used as a vegetable in many countries. The leaves are highly nutritious and medicinal in nature. They are a rich source of iron, calcium, vitamin A, vitamin C, proteins, and essential amino acids. Hence Moringa leaves can be a good source of protein for the vegetarians and the under-nourished population. Present investigation deals with the study of monthly variation in the nutritional value of Moringa leaves from the month of June 2015 to January 2016. Impact of urban sewage pollution and roadside vehicular pollution on the amount of reducing and total sugars, chlorophylls (a, b and total), proteins, vitamin-C and pH of the leaves, was also studied. Results revealed that the highest amounts of reducing sugars, total sugars, chlorophyll b and total chlorophyll during October 2015 whereas proteins, chlorophyll a, vitamin C and pH were highest during January 2016. Leaf samples collected from all the study sites exhibited minimum amounts of reducing sugars, chlorophylls (a, b and total) and pH during July 2015 whereas total sugars were lowest during December 2015. Proteins and vitamin C values were lowest during August and June 2015 respectively. Sewage and vehicular pollution showed an adverse effect on the nutritional contents of Moringa oleifera leaves. Of the two polluted sites, samples from near the sewage flow showed higher impact.

Moringa oleifera leaves (MOL) have gained great interest as a non-traditional feed ingredient due to their unique nutritional value. Therefore, the objective of the current study was to evaluate the effects of graded dietary supplementation levels with MOL on performance, carcass characteristics, antioxidant capacity, blood biochemical constituents, meat quality, and fatty acids profile of growing rabbits. A total of 120 weaned New Zealand white rabbits (6 weeks old) were randomly allotted into 4 dietary groups with 5 replicates each (n = 6), which were fed for 42 days with a basal diet as control or 3 experimental diets supplemented with 5, 10, or 15 g/kg MOL. The results showed that, compared to the control group, the dietary inclusion of MOL at a level of 10 and 15 g/kg DM linearly increased (p < 0.01) final live weight (2403.3 and 2498.2 vs. 2166.6) and average daily weight gain (36.5 and 35.51 g/d vs. 28.72 g/d), and enhanced feed conversion ratio (2.49 and 2.50 vs. 3.14). The dietary supplementation with MOL linearly increased dressing out percentage, spleen index, intestinal length, and decreased abdominal fat index (p < 0.01). Greater serum levels of total protein and globulin, but lower alanine aminotransferase and aspartate aminotransferase were observed in the MOL-fed rabbits (p < 0.01). Serum levels of total triglycerides, cholesterol, and low-density lipoprotein (p < 0.05) were decreased linearly and quadratically in the MOL groups compared with the control. Glutathione peroxidase activity increased (p < 0.01), whereas malondialdehyde decreased (p < 0.01) linearly and quadratically in both serum and meat, in response to dietary MOL supplementation. Dietary MOL supplementation increased the meat crude protein content but lowered the relative content of ether extract in the meat (p < 0.05). The relative content of the meat n-3 PUFA was increased by about 33.71%, 29.46%, and 24.36% for the MOL0.5%, MOL1%, and MOL1.5% groups compared to control. In conclusion, MOL could be used at a level of 1.5g/kg of the growing rabbits’ diets with beneficial impacts on performance, antioxidant capacity, and the nutritional value of the meat.

The reuse of solid and liquid wastes has become a viable practice for the sustainability of agricultural production, because it meets the nutritional needs of crops and also allows the use of nutrients present in these residues. The objective of this work was to analyze the nutritional value of Tifton 85 irrigated with treated domestic wastewater and fertilized with nitrogen doses from poultry bed in four successive cuts, with frequency of 35 days. The experiment was set up in a protected environment, arranged in a completely randomized experimental design, in a 5 × 2 factorial scheme, with four replications. Five doses of nitrogen were tested through organic fertilization from avian beds (0, 15, 30, 45 and 60 kg N ha-1) and two irrigation water qualities (treated domestic well and artesian well). After the cuts the material was dried and sent to the laboratory to determine the following parameters: crude protein (CP), neutral detergent fiber (NDF) and Tifton 85 acid detergent fiber (ADF). The highest values of crude protein were obtained using the domestic wastewater treated in the irrigation, as well as using the higher doses of nitrogen from poultry litter. Just as the NDF and ADF contents presented the best values when treated domestic wastewater and the highest nitrogen doses. Indicating that irrigation with wastewater and the use of organic fertilizer may substitute for conventional manures by promoting satisfactory levels of concentrations for fodder.

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower silages were determined. In both silages there was increment of dry matter, non-fiber carbohydrates and total digestible nutrients (TDN) added to a reduction of crude protein, neutral detergent fiber and acid detergent fiber due to the glycerol inclusion. The corn silage required 45% glycerol to achieve the TDN level of the sunflower silage. The glycerol addition contributed to the increase in the nutritional value, offsetting loss of quality in the ensiling process.

The goal of this study was to assess the dehydration curve and nutritional value of Tifton 85 bermudagrass at two cutting heights from ground level (4 and 8 cm) during 120 days of storage in a closed shed. The dehydration curve was determined using samples from the entire plant at eight different times. The experimental design consisted of randomized blocks with plots subdivided per times and five replicates. The second step consisted of assessing the nutritional value of the stored Tifton 85 bermudagrass in randomized blocks with plots subdivided per times and two treatments per plot: cutting height of four and eight centimeters from the ground, and five different times for the subplots, with five replicates. Dehydration of Tifton 85 bermudagrass at the two heights occurred in 48 hours, considered an ideal time for hay drying. The dry matter content responded quadratically to the time of storage of the two heights, only differing during baling and after 120 days of storage. Crude protein content had a quadratic behavior in the two cutting heights, with the smallest value after 30 days of storage (107.0 g kg-1) and the largest after 90 days (147.8 g kg-1) in the cutting height of eight centimeters. The ether extract exhibited a quadratic behavior in the two cutting heights, only differing after 90 days of storage. The neutral detergent fiber content had linear positive response according to the time of storage, with no difference between the cutting heights. For the neutral detergent fiber content in the two cutting heights, the quadratic regression model was the best fit to the data, differing between the heights after 30 and 60 days of storage. In vitro dry matter digestibility and in vitro cell wall digestibility values of the stored hay were lower than the values obtained at the time of cutting. Cutting performed at four centimeters from the ground was the most suitable for hay production due to higher dry matter production and nutritional value without difference between bailing treatments. Hay storage caused undesirable changes in the nutritional value, especially in fiber content and in vitro digestibility.

<p>Para cuantificar la degradación <em>in situ </em>de tejidos vegetales y su relación con la composición química de especies forrajeras se seleccionaron láminas foliares de las gramíneas <em>Bouteloua repens </em>y <em>Bothriochloa pertusa </em>y foliolos de las leguminosas <em>Stylosanthes scabra</em>, <em>Desmodium barbatum </em>y <em>Tephrosia cinerea</em>. En el rumen se incuba­ron muestras de 10 mm de largo durante 0, 12, 24, 48 y 72 horas; para la lectura del área residual se digitalizaron ocho tejidos. A las 24 y 48 h de incubación <em>B. pertusa </em>presentó relaciones positivas entre la degradación de la epidermis adaxial (EA) y la FDN (R2= 90,2), entre el mesófilo y la DIVMS (R2=80,1), y entre los tejidos len­tamente degradables (TLD) y la FDA (R2= 83,9); y relaciones negativas entre EA y DIVMS (R2= –73,1), los TLD con la DEF (R2= –74,3), la EA con la PC (R2= –87,6), y el esclerenquima con la DIVMS y la PC (R2= –84,3 y R2= –90,8). Después de 72 horas de incubación las mayores áreas residuales en gramíneas fueron la estructura kranz entre 34,2% y 36,5%, el mesófilo entre 20,9% y 21,4%, el xilema de 11,5% a 17,1% y la EA entre 11,8% y 13,9%; no obstante el esclerénquima se relacionó estrechamente con indicadores de calidad nutricional. Las gramíneas obtuvieron mayores porcen­tajes de tejidos no degradables que las leguminosas; por lo tanto, la DIVMS y la DEF fueron menores. Entre las leguminosas, <em>S. scabra</em>, presentó la mayor digestibilidad de los tejidos rápidamente degradables, tanto en sequía como en lluvia; en la época seca se incrementó en 134,6% la degradación de estos tejidos. Adicionalmente, en esta especie el área residual de los taninos no presentó relación directa con la degra­dación del mesófilo. En leguminosas la tasa y extensión de la degradación de las epidermis se incrementaron marcadamente a mayor tiempo de incubación, presen­tándose diferencias entre especies, situación que no exhibieron las gramíneas. En <em>D. barbatum </em>la degradación de la EA se asoció con la DIVMS y la DEF, explicando en 77,4% y 72,95% estos porcentajes; de igual manera se reportaron relaciones negati­vas entre la degradabilidad de la epidermis y los porcentajes de FDN, FDA, lignina y taninos (R2= –0,76; R2= –0,79; R2= –0,53 y R2= –0,76, respectivamente).</p><p> </p><p><strong>Microbial <em>in situ </em>degradation of grasses and legumes leaf tissues and its realtionship with nutritional quality and precipitation</strong></p><p>A study was conducted to measure the <em>in situ </em>de- gradation of plant tissues and its relationship with forage chemical composition in leaves of the grasses <em>Bouteloua repens </em>and <em>Bothriochloa pertusa </em>and of the legumes <em>Stylosanthes scabra</em>, <em>Desmodium barbatum </em>and <em>Tephrosia cinerea</em>. Forage samples of 10 mm in length were incubated in the rumen for 0, 12, 24, 48 and 72 h and tissue residual area was determined by reading the residual area in eight digitalized leaf samples per forage. In <em>B. pertusa</em>, after 24 and 48 h of incubation there were positive relations between the degradation of adaxial epidermis (AE) and the neutral detergent fiber (NDF, R2 = 90.2), between mesophyll and in vitro dry matter degradability (IVDMD, R2 = 80,1), and between slowly degradable tissues (SDT) and the acid detergent fiber (ADF, R2 = 83.9); and negative relationships between AE and IVDMD (R2 = -73,1), between SDT and effective dry matter degradation (EDMD, R2 = -74,3), between AE and crude protein (CP, R2 = -87,6), and between sclerenchyma and IVDMD with CP (R2 = -84,3 and R2 = -90,8, respectively). After 72 h of incubation, the greater residual areas in grasses were the Kranz structure (34.2% to 36.5%), mesophyll (20.9% to 21.4%), xylem (11.5% to 17.1%) and AE (11.8% to 13.9%). The area of sclerenchyma was related close­ly to indicators of nutritional quality. Overall, the grasses had greater content of non-degradable tis­sues than the legumes; therefore, their IVDMD and EDMD were lower. Among the legumes, <em>S. scabra </em>showed the greater digestibility of rapidly degrada­ble tissues, both during the rainy and dry seasons. At the dry season, the degradation of these tissues increased by 134.6%. Additionally, in this legume, the content of tannins did not have a direct relation­ship with the degradation of mesophyll. The rate and extension of the degradation of epidermis in legumes, were noticeably increased with increasing length of incubation, existing differences between species, a situation which was not observed in the grasses. In <em>D. barbatum</em>, the degradation of the AE was positively associated with both the IVDMD and EDMD (R2 = 77,4% and 72,95%, respectively). On the other hand, the degradability of epidermis and the percentage of NDF had negative relations with ADF, lignin and tannins (R2 = -0,76; R2 = -0,79; R2 = -0,53 and R2 = -0,76, respectively).</p>

Moringa oleifera is a foliated tree widely cultivated in tropical latitudes, which is highly adaptable to climatic conditions and dry soils. Every part of the plant has nutritional, therapeutic or industrial benefits. This is due to its phytochemicals such as glucosinolates, phenolic compounds, alkaloids, terpenoids and tannins, high values of crude protein, carbohydrates, starch and lipids. In addition, the use of the leaves has increased considerably by the agro-food and biochemical industries since they are a valuable source of dietary proteins and essential amino acids. This work aimed to characterize three types of leaf from Moringa oleifera seeds with different origins (Thai (C1), Ghana (C2) and India (C3)), grown in the same plot, but with different cultural practices (intended for leaf production (C1 and C2) or sheath production (C3). For this, water content and optical properties were determined in the fresh leaves. Later the leaves were dried (50 °C for 8 h) and pulverized, analyzing their water content, antioxidant capacity, color and amino acid content. No significant differences were observed in fresh leaves in terms of humidity and color. In dry powder, a higher antioxidant capacity was registered in moringa type C2, with a% DPPH inhibition of 83.7%, although in all cases, it exceeded 60%, showing the high persistence of the antioxidants after drying. Serine, glutamic acid and alanine were the major amino acids with values of 373 ± 78, 301 ± 51 and 248 ± 9 mg/100 g of powder, respectively, without influencing the applied field treatment or origin.

The research aimed to identify the most productive hybrids selected by the All-Russian Research Institute of Maize to cultivate by the cereal seed technology in the natural conditions of the Middle Cis- Urals. Methodology. Maize was cultivated for seeds and green fodder for farm animals in the conditions of the Middle Cis-Urals. The maize green mass, consisting mainly of stems and leaves, usually contains up to 88-90% water. Silage being prepared for it has less dry matter and protein. Such fodder has low nutritional value and poor return from livestock products. The most high quality and nutritious feed can be received from maize seeds or its above-ground mass with seeds of milky-wax and wax ripeness. To select early-maturing hybrids with high nutritional value is the primary concern for the studied area. Results. The results demonstrate that the productivity of maize hybrids ranges from 2.50 to 6.76 t/ha depending on soil and climatic conditions. When maize hybrids are grown by seed technology, the above-ground mass of the studied crops is 30.68-68.80 t/ha. Conclusions. It is necessary to select earlier ripening and highly productive hybrids to increase the quality and nutrition of corn feed. The recommended hybrids for grain production are Ural 150 (5,45 t/ha), Baikal (5,38 t/ha) and Mashuk 170 MV (4,98 t/ha); K-170 (56,7 t/ha), Shihan (55,67 t/ha) and Mashuk 170 MV (54,99 t/ha) that provided a higher output of the green mass at milky-wax ripeness of grain are best for silage production. The resulting data make it possible to select maize hybrids with high yields and nutritional value for farms with similar soil and climate conditions and to develop diets for highly productive dairy and beef cattle.
