Abstract: The objective of this work was to assess the nutritive value of four elephant grass (Pennisetum purpureum) genotypes. The chemical composition, intake by sheep, and digestibility of different genotypes (G1, G2, G3, and G4) were evaluated. A dry matter (DM) digestibility assay was performed with total leftovers and feces collected from 20 sheep kept in metabolic cages. G3 had lower DM intake in grams per animal per day compared with G1 and G2, and it had greater digestibility, crude protein, neutral detergent fiber, and acid detergent fiber values. G1, G2, and G4 have the best nutritive values among the evaluated genotypes.

Plot Design

This study evaluated the inclusion of increasing contents (0; 35; 70; 105 and 140 g kg-1) of dried acerola fruit (Malpighia glabra, Linn.) by-product (DABP) in the ensilage of elephant grass (Pennisetum purpureum, Schum.) considering the in situ degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose. Plastic drums with 210 L capacity were used as experimental silos. After 45 days of ensiling, silos were opened and silage samples were collected for the degradability trial and laboratory analysis. For the in situ degradability trial, was used one rumen-fistulated adult male cattle. The five by-product inclusion contents were tested in three replicates, with five incubation times, in a randomized complete split-plot design in which the contents of DABP were the treatments (plots), the different silos were the replicates and the incubation times were the sub-plots. Longer incubation times significantly increased (P < 0.05) the disappearance rates of DM, CP, NDF, ADF and hemicellulose. The effective degradability of the DM, NDF and hemicellulose was higher in the silages with 35 g kg-1 of DABP in the rumen passage rates of 0.02; 0.05 and 0.08 h-1. Dried acerola fruit by-product can be added to elephant grass ensiling up to 35 g kg-1 without reducing the effective degradability of nutrients.

Cassava Peel

In this study, elephant grass ((Pennisetum purpureum) was ensiled with varying levels of poultry dropping and cassava peel (CSP). Silage characteristics and chemical composition of the silage mixtures were determined in the laboratory while preferences of West African Dwarf (WAD) goats for the mixtures were assessed using eighteen (18) WAD goats. The treatments were: T1: P. purpureum (60%), poultry dropping (40%), dry cassava peel (0%); T2: P. purpureum (60%), poultry dropping (30%), dry cassava peel (10%); T3: P. pupureum (60%), poultry dropping (20%), dry cassava peel (20%); T4: P. purpureum (60%), poultry dropping (10%), dry cassava peel (30%); T5: P. purpureum (60%), poultry dropping (0%), dry cassava peel (40%) and T6: P. purpureum (100%). All the mixtures formed good silage, except the silage with the highest proportion of poultry dropping (T1) and acidity (pH) ranged from 6.75 to 3.80 (T1 and T5 respectively) while colour varied from pale to light green with dark brown and white speckles as proportion of cassava peel in the silage mixture increased. All silages had firm texture with pleasant and slightly alcoholic smell. Dry matter (DM) content of silage increased as proportion of cassava peel in the mixture increased while crude protein (CP) and (NDF) reduced. DM, CP and CF varied from 27.00 to 54.00%, 8.46 to 10.72% and 28.52 to 60.52 %, respectively. The preference by goats was 11.22, 20.44, 20.71, 21.78, 22.56 and 32.28% for T5, T4, T6, T3, T2 and T1 respectively. These results revealed that the silage properties, chemical composition and acceptability of elephant grass silage by WAD goat were enhanced by the addition of cassava peel and poultry dropping to elephant grass

Matter Basis

The effect of using conventional urea (CU) or slow release urea (SRU) was evaluated by replacing soybean meal (SBM) in concentrated supplements in levels of 2, 4 or 6% (dry matter basis) on productive performance of crossbred Holstein x Zebu lactating dairy cows (499±61kg body weight and 167 days of lactation) grazing on elephant grass (11.5% CP and 60% NDF) under rotational grazing during the rainy season. A supplement control (no urea) was used containing SBM as a protein source. A total of 21 cows were distributed an incomplete randomized block design with three periods of 21 days each (14 days of adaptation and seven days of collection). The animals entered the paddocks with a pasture height of 110-120cm and left when the grass reached the height of 40-50cm. The concentrated isonitrogenous supplements (24% crude protein, dry matter basis) were provided in the amount of 3.2kg/cow/day (fed basis). There was no effect (P>0.05) on source of crude protein (SBM vs source NPN), source NPN, level of NPN, interaction between source NPN and level of NPN on milk production (10.0kg/day), fat milk production corrected to 3.5% (10.7kg/day), levels of fat (4.01%), protein (3.66%), lactose (4.16%), total solids (12.86%) and non-fat solids (8.60%) in milk. The replacement of CU by SRU does not promote improvement in the productive performance of crossbred dairy cows grazing on elephant grass during the rainy season. Urea (CU or SRU) can be included in up to 6% of the DM concentrated supplements, replacing SBM, without affecting the productive performance of crossbred cows (Holstein x Zebu) in pasture during the rainy season.

The objective of this experiment was to evaluate the effects of adding cassava scrapings on gas and effluent losses, dry matter recovery, pH, contents of N-NH3, organic acids and volatile fatty acids and the bromatological composition of elephant grass silages. It was used a randomized complete design, with four levels of cassava scrapings (0, 7, 15 or 30% natural matter) each one with four replications per level. The grass was cut at 50 days of regrowth and ensiled in 15-L silos, equipped with a Bunsen valve to allow gas outflow. The gas losses decreased quadratically with the addition of cassava scrapings, whereas effluent losses decreased linearly. Dry matter recovery increased quadratically with the addition of cassava scrapings. Dry matter (DM) concentration increased but crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose (HEM) decreased linearly with the addition of cassava scrapings. The pH value and lactic acid concentration increased quadratically with the addition of cassava scrapings. Contents of N-NH3 and butyric acid decreased quadratically with the addition of cassava scrapings, whereas acetic acid content decreased linearly. Addition of cassava scrapings reduced gas and effluent losses and improved the fermentation profile of elephant grass silages and the level of 7% already ensures this improvement.

AbstractThis study examined whether work applied at different stages of lactation had any effect on reproduction of cows under two feeding regimes. Twenty-four F1 crossbred dairy cows (12 Friesian × Boran and 12 Simmental × Boran) were allocated one of two diets (H + 3: natural pasture hay + 3 kg concentrate per day; and H + 5: natural pasture hay + 5 kg concentrate per day) and one of three work treatments — starting 45 days (D45), 90 days (D90) and 135 days (D135) post partum — using a principal component analysis score based on milk yield, live weight, calving interval and parity. Cows pulled sledges for 50 days (pull = 108 N per 100 kg live weight). Over the experimental period of 315 days, cows on diet H + 5 travelled a similar distance and produced amounts of fat-corrected milk (FCM) similar to those of cows on diet H + 3. Total intake of dry matter per kg live weight 0·75 was higher for cows on diet H + 5 than for cows on diet H + 3 and was similar across work times. Hay dry-matter intake was greater for the H + 3 group than for the H + 5 group at 180 days post partum and thereafter. Cows on diet H + 5 lost less weight in early lactation and gained more in mid and late lactation than cows on diet H + 3. During the work period, live-weight change was similar across diets but it was different between work treatments D45 and D135. The interval from calving to conception decreased by 63 and 101 days when start of work was delayed from D45 to D90 and from D45 to D 135, respectively. Output/input ratios of metabolizable energy equivalents were 0·35 for H + 3 and 0·37 for H + 5 diet, and 0·34, 0·37 and 0·40 for work times D45, D90 and D135, respectively. These results indicate that work started in early lactation significantly increased days to conception and decreased overall productivity of lactating working cows. Farmers must weigh the relative importance and cost of delayed ploughing against those of delayed oestrus or against the cost of borrowing draught power.

"Shika" (indigenous, V,) and "Ngala" (introduction, V2) varieties of elephant grass (Pennisetum  purpureum Schum.) field planted at 60 x 90, 60 x  60 or 60 x 30 cm spacing and fertilized at 0, 100,  200 or 400kg N/ha/yr, were examined for dry matTer (DM) yield, crude protein (CP) content, CP  yield, nitrogen (N) recovery and stand persistence at  Shika during the 1975 and 1976 growing seasons.  The highest DM yield resulted from 60 x 30 cm  spacing/400kg N combination but the 60 x 60 cm  spacing (27,800 plants/ha) with 200kg N appeared  optimum for yield. V produced 4.3 to 21.0t DM  and V2 2.8 to 17.41 DM/ha/yr over the range of  population densities and fertilizer levels investigated. DM yield per kg N applied rose with increasing population density (V, only) and decreasing  N rate, the highest value of 49kg being recorded for V t. Mean herbage CP content varied from 7.0% without N to 9.7% with 400kg N/ha but the highest value of 11.0% was obtained from V2 planted at 60 x 90cm. For both grasses, N increased annual CP yield 1.2— 4.5—Fold. The highest apparent fertilizer N recovery of 76.3% occurred at 200kg N/ha while plants survived best at 60 x 60cm spacing.

Changes in the colostrum nutritive value were studied in dairy cows of the Czech Red Pied x Holstein (n = 10) from the 2nd to 72nd hour post partum. Of them, five and five animals were in the first and the second (or higher) lactation, respectively. Dry matter (DM) content ranged from 20.37 to 13.78% (mean value 15.61%). Within the first 12 and 72 hours after parturition, the shares of crude protein in DM were more than 60% (14.33 – 9.71%) and nearly 50% (6.34 – 4.06%; mean 5.61%), respectively. Milk fat made one quarter (2.29 - 5.16%; mean 3.72%) and lactose approximately 22% (2.74 - 3.93%; mean 3.43%) of DM content, respectively.

Community farms mostly only use the main products of the farm alone, did not see many more opportunities of byproducts such as feces and urine of livestock. Byproducts can be used for very useful organic fertilizers from crops especially forage for animal feed such as mini elephant grass (Pennisetum purpureum schamach) which is able to grow in various types of soil and is a grass of high nutritional value of fiber favored by livestock. The purpose of this study was to examine the effects from the provision of feces and urine buffalo mud and cutting intervals on the production and nutritional content of Pennisetum purpureum schamach. This research has been conducted at the Faculty of Agriculture, University of Sumatra Utara from July to October 2015. This study used Split Plot Design, consisting of cutting interval (4 weeks and 6 weeks) as main plot and type of fertilizer (control / no fertilizer application, mud buffalo feces, buffalo feces + non fermented urine buffalo and feces from buffalo mud + urine fermentation) as subplot. The observed variables were plant height, fresh production, dried production, number of tillers, crude protein and crude fiber from Pennisetum purpureum schamach forage. Cutting intervals have a significant effect on improving nutritional content such as crude protein and crude fiber of mini elephant grass. The interaction of the results showed that the provision of impurities from mud buffalo (feces and urine) gave a real effect to increase fresh production, dry matter production, plant height and number of mini elephant grass. The interaction of the results showed that the provision of impurities from mud buffalo (feces and urine) gave a real effect to increase fresh production, dry matter production, plant height and number of tillers mini elephant grass.. Provision of mud buffalo dung (feces and urine) showed a real interaction with fresh production, dry matter production, plant height, number of tillers, crude protein and crude fiber.Keywords:Pennisetum purpureum Schamach, feces, urine, and and forage productivity
