  • This study presented a measure for turning by-products, released from land farming sites, into resources. The measure involved adding food by-products such as rice bran and nonfat soybean to the sludge, released from the eel farming sites, inoculating the lactic acid bacteria, Aspergillus oryzae, and Bacillus subtilis by step, fermenting them, and measuring the changed ingredients of the fermented fodder. The water content of the fermented fodder by the step of preparation was the first-step fermented product (14.6%) using the lactic acid bacteria, and the second and third-stage fermented product (33.0% and 34.0% respectively) using Aspergillus oryzae and Bacillus subtilis. The pH level was found to be 5.38 in the first-step fermented product due to the secretion of lactic acid caused by the lactic acid bacteria, and the pH level of the second and third-stage fermented products was 5.66 and 7.26, respectively, showing that the pH level increased. The phytic acid content was 0.126g/100g in the first-step fermented product, 0.004g/100g in the second-stage fermented product, and 0.093g/100g in the third-stage fermented product. The measurement of nitrogen content revealed that the amino nitrogen content was high with 1226.37mg% in the second-stage fermented product, and a little lower with 710.18mg% in the third-stage fermented product. The ammonium nitrogen content increased from 0.988mg/kg in the first-stage fermented product to 1.502mg/kg in the third-stage fermented product. Total nitrogen content increased to 2.78% in the first-stage fermented product, 4.08% in the second-stage fermented product, and 4.85% in the third-stage fermented product. As fermentation continued with the three microbes, the phytic acid decreased, and the protein decomposition rate increased. Also, due to the 3 step fermentation, the low-molecule nitrogen ingredient content increased, suggesting that the fodder was developed to offer high digestion and absorption.

  • Two promising varieties of forage sorghum viz. HD-15 and J. Sel-10 were identified for their higher forage yield (350-400 quintals per hectare) compared to traditional/existing variety, HC-136 at Indian Grassland and Fodder Research Institute, Jhansi. Silage of these three forage sorghum varieties viz., HD-15, J.Sel-10 and HC-136 were prepared in three concrete silos for their nutritional evaluation in sheep. Twelve adult Muzaffarnagari Ewes, divided into three equal groups of 4 each, were offered a particular variety of sorghum silage ad libitum over a period of 30 days followed by a 6 day metabolism trial and a collection of rumen liquor and blood samples. The HD-15 variety of forage sorghum silage contained higher crude protein (CP) than both the J.Sel-10 and HC-136. Average daily dry matter (DM) intake (% of live weight) differed significantly (p<0.05) in sheep that were fed the different varieties of silage, with the maximum amount in HD-15 (2.55) followed by J.Sel-10 (2.49) and HC-136 (1.84). The average apparent digestibility of all the nutrients was low in the sheep that were fed the HC-136 variety of sorghum silage when compared to both HD-15 and J.Sel-10. However, digestibility of organic matter (p<0.05) and crude protein (p<0.01) was significantly low in the HC-136 variety. The average daily nitrogen retention was-0.19, 2.15 and 0.42 g in HC-136, HD-15 and J.Sel-10, respectively which differed significantly (p<0.01). The average digestible crude protein and total digestible nutrient (TDN) contents (%) of the silage varieties were higher in HD-15 (3.14 and 55.3) than HC-136 (0.25 and 58.6) and J.Sel-10 (1.58 and 55.3) varieties. On comparing to the maintenance requirements (ICAR, 1985) for dry matter, crude protein and total digestible nutrients, both the improved varieties (HD-15 and J.Sel-10) almost met the requirements except crude protein, which met only 73.3% of the requirement by J.Sel-10, while the HC-136 variety was unable to meet the requirements. The average rumen pH and total volatile fatty acids concentrations were comparable among the groups. However, concentrations of nitrogen metabolites were higher in the animals fed the HD-15 variety of silage. Varieties of sorghum silage also did not have any influence on the concentration of the blood metabolites. It was concluded that the HD-15 variety of sorghum silage was nutritionally superior to both J.Sel-10 and HC-136 silage.

  • Barley is an important cereal gain which is traditionally used in some nations of Asia and North Africa, and there has been growing interest in using barley as an ingredient in food due to their nutritional value and high content of phyto-constituents. However, no study report on comparative feed value between sprouted barley, cornflake and alfalfa hay. Therefore, in this study we aimed to evaluate the chemical composition, amino acid profile and mineral content of 6 day sprouted barley fodder (SBF) compared with cornflake and alfalfa hay using by AOAC method, as an alternative feed ingredient. Results showed that SBF had higher content of crude protein, acid detergent insoluble crude proteins and neutral detergent insoluble crude protein than alfalfa hay and cornflake; cornflake had higher crude fiber, neutral detergent fiber content than SBF and alfalfa hay; alfalfa hay had higher crude fiber, crude ash, acid detergent fiber, neutral detergent fiber and lignin level than SBF and cornflake. Also, significant differences were found on amino acid content among them (p<0.01). The most abundant amino acid in SBF was glutamate (123 g/kg DM), which is higher than in alfalfa hay (1.27%) or cornflake (1.58%). However, methionine (1.33%) and cysteine (1.53%) were the least abundant amino acids in SBF compared with cornflake or alfalfa hay. Furthermore, our study results exhibited that SBE comprise a good sources of minerals including ferrous (90.01 mg/kg) followed by zinc (20.50 mg/kg), magnesium (0.20 mg/kg) and sodium (0.03 mg/kg) as compared to cornflake and alfalfa hay. The present research findings, confirmed that the nutritional values of SBF are comparable to those of cornflake and alfalfa hay. Hence, SBF can be a better alternative feed ingredient for cornflake or alfalfa hay. However, feeding trials will be required to determine acceptability of SBF for ruminant production.

  • Pearl millet (Pennisetum americanum (L.) Leeke) is a promising forage crop that is resistant to biotic and abiotic stresses, and has a capability to grow well not only in the fertile soil, but also in the poor and dry soil, The objective of the study was to investigate the effects of increased fertilizer application level on the productivity and Quality of pearl millet in the old and newly reclaimed upland soils of Suwon, Chungju, Jeonju, Jinju and Jeju in Korea from 1986 to 1988, Plant height, green fodder yield, protein content and digestibility were increased by the increased fertilizer application level. However, the increased fertilizer application caused lodging, so that the plants grown above one meter in canopy height would be desiable to be clipped remaining 20cm above the ground surface before lodging, and fed to cattle, Mean green yields of the N 45-60kg/l0a application were 12.7-13.4t/l0a in the old upland soil. Increased phosphorus and potash fertilizer application also increased productivity, especially with potash fertilizer effect being higher than that of phosphorus fertilizer, In the newly reclaimed upland soil, improved and doubled fertilizer application plot of 60-60-40-4000kg/10a in N-P$_2$O$\sub$5/-K$_2$O-Compost was 38% higher being 12.6t/10a of green fodder yield as compared with standard fertilizer application plot, Pearl millet productivity and Quality were higher than those of maize and sorghum/sudan grass hybrids, particularly in green fodder yield, protein content and digestibility.

  • The objective was to evaluate the effect of fodder tree species (FTS) with condensed tannin contents: Cordia elaeagnoides, Platymiscium lasiocarpum, Vitex mollis, and Haematoxylon brasiletto, on in vitro methane ($CH_4$) production at 24 h post incubation. The analysis was performed using the in vitro gas production technique, with three levels of inclusion/species: 600, 800, and 1,000 mg and with 4 replicates/species/level of inclusion. The substrate was incubated at $39^{\circ}C$, and the gas and $CH_4$ production were recorded at 4, 8, 12, and 24 h post incubation. The data collected was analyzed through Pearson correlation, polinomial regression and fixed effects models. There were negative correlations between FTS-total gas volume (r = -0.40; p<0.001); FTS-volume of $CH_4$ produced (r = -0.40; p<0.001) and between the inclusion level-volume of $CH_4$ produced (r = -0.20; p<0.001). As well as a positive correlation between hours post incubation-total gas volume (r = 0.42; p<0.001) and between hours post incubation-volume of $CH_4$ produced (r = 0.48; p<0.001). The FTS: C. elaeagnoides, V. mollis, and H. brasiletto have potential, in the three inclusion levels analyzed, to reduce $CH_4$ emission on in vitro trials (>32.7%), taking into account the total $CH_4$ production at 24 h of the forage used as reference (Avena sativa). It's suggested that C. elaeagnoides-according to its crude protein, neutral detergent fiber, and condensed tannins content- is the best alternative within the FTS analyzed, for feeding ruminants and for the control of $CH_4$ emissions during the dry season.

  • Twenty small-scale farms of two villages (A and B) were surveyed to identify the feeding traits, milk productivity and nutritional status of lactating cattle and buffalo in Terai, Nepal. Constituents and dry matter (DM) of feed supplied, body condition score (BCS), heart girth (HG), bodyweight (BW), milk yield (MY) and plasma metabolites were obtained in the pasture-sufficient, pasture-decreasing and fodder-shortage periods. Milk yield of 305-day lactation was estimated by the daily MY. The supplies of rice straw and native grass were lower and higher in the pasture-sufficient period than in the other periods, respectively (5.5 kg/day vs. 9.8 kg/day and 3.2 kg/day vs. 0.4 kg/day, respectively, p<0.01). The roughage-supplement rates of the animals were higher in village A than in village B (5.0 vs. 2.2 in cattle and 9.3 vs. 1.8 in buffalo, p<0.01). The variance of feed constituents among the periods and between the villages induced different supplies of CP, NDF and TDN. The concentrations of CP and TDN in the cattle feed were higher in the pasture-sufficient period than in the other periods (9.1% vs. 7.3% and 57.4% vs. 51.0%, respectively, p<0.01). The supplies of CP for cattle and buffalo, and of TDN for buffalo were lower in village A than in village B (7.5% vs. 8.7% and 6.6% vs. 9.1% [p<0.01], and 53.1% vs. 56.2% [p<0.05], respectively). The BCS, HG and BW of the animals were lower in village A than in village B (2.51 vs. 2.86, 156 cm vs. 170 cm and 300 kg vs. 318 kg, respectively in cattle, 2.83 vs. 4.00, 186 cm vs. 216 cm and 429 kg vs. 531 kg, respectively in buffalo, p<0.01). The cattle yielded more milk in the pasture-sufficient period than in the other periods (7.9 liters/day vs. 6.6 liters/day, p<0.01). The 305-day MY of cattle that calved in the fodder-shortage period was lower than that of cattle that calved in the other periods (1,900 liters vs. 2,251 liters, p<0.01). The MYs of cattle and buffalo were lower in village A than in village B (6.2 liters/day vs. 8.1 liters/day and 3.7 liters/day vs. 7.7 liters/day, respectively, p<0.01). The 305-day MY of cattle was lower in village A than in village B (1,935 liters vs. 2,409 liters, p<0.01). The concentrations of plasma albumin and urea nitrogen in cattle were lower in village A than in village B (3.2 g/dl vs. 3.4 g/dl [p<0.01] and 7.4 mg/dl vs. 10.2 mg/dl [p<0.05], respectively). The different supplies of CP, NDF and TDN among the periods and between the villages might have affected MY and nutritional status in cattle and buffalo. It was likely that the lower supplies of CP and TDN for cattle that calved in the fodder-shortage period and in village A lowered the 305-day MY of cattle.

  • The suitability of female cattle ($Brahman{\times}Holstein$) and buffaloes (Murrah / Jafarabadi) for work on a sugarcane crusher was tested. The animals were fed chopped sugarcane tops and elephant grass supplemented with rice bran and urea-molasses blocks. In experiment 1, six cattle and six buffaloes, (with three animals seven to eight months pregnant at the start of the experiment in each group), worked individually, alternate weeks for 90 minutes a day for 6 d/week. Within the 90 min, cattle did more work than buffaloes (p < 0.05), and non-pregnant animals did more than pregnant animals, but cattle crushed significantly (p < 0.05) more cane per day than buffaloes. During work animals lost weight, but gained the weight back during resting weeks, when fodder intakes were higher. There were no significant differences in live weight change and fodder intakes between pregnant and non-pregnant animals during the six weeks. In experiment 2, four pairs of lactating cows and buffaloes crushed sugarcane for 3 h/d, 6 d/week for three weeks. Work done was higher in cattle than buffaloes, but cane crushed was marginally lower. All animals lost weight during work, particularly in the first week, but gained weight during the week after work. Daily milk yield was lower during the working weeks ($-0.55{\pm}0.15kg$) than in the week before work. Butter fat yield showed no significant change. One buffalo showed ovarian activity and oestrus behaviour during the work. Two cows showed ovarian activity within one month after the work. It was concluded that pregnant and lactating cows and buffaloes can effectively operate a cane crusher, however a temporary reduction in milk yield can be expected in the working period, and ovarian activity may be suppressed.
