The yield, intake and animal production of four grass species namely: Cynodon nlemfuensis var. robustus, Pennisetum purpureum Schum; Cynodon nlemfuensis var nlemfuensis (Ib8) and Panicum Maximum Jacq., designated as treatments M, N, P, and respectively, were studied over a period of 1,226 days. Each treatment was grazed at three stages of growth - at four, six and eight week intervals. Total dry matter yields for the experimental period ranged from approximately 22 tons for treatment N grazed at intervals of four weeks to 65 tons for treatment Q grazed at eight week intervals. The mean daily dry matter yield varied between approximately 18 kg for treatment N to 53 kg for treatment Q grazed at four and eight week intervals respectively. With the exception of treatment N, dry matter intake by sheep per kg of metabolic size per day decreased with increased maturity and ranged from 43 kg in treatment N to 86 kg in treatment P grazed every four weeks. Treatment means of liveweight increases of grazing White Fulani (Zebu) steers were 392 g, 360 g, 337 g and 226 g per head per day for treatments Q, N,P and M respectively. Though the protein content of the pastures was high enough even in the dry season to maintain the grazing animals, dry matter production and intake were usually very low.

SUMMARYThe yields of four tropical grass/legume pasture mixtures were studied over a 4-year period. These mixtures had the following composition: H, Cynodon nlemfuensis var. robustus, together with the legumes Centrosema pubescens (Benth.), and Stylosanthes gracilis (H.B.K.); J, Pennisetum purpureum (Schum.) plus the two legumes in H; K, treatment J mixture plus Panicum maximum (Jacq.); and L, a mixture of treatments H, J and K. Each treatment paddock was grazed in rotation between 19 April 1966 and 21 November 1969.The mean annual dry-matter yields over the 4 years of grazing were approximately 37 ± 5·7, 41 ± 2·6, 44 ± 10·2 and 47 ± 8·7 t/ha for treatments H, J, K and L respectively. The overall mean for the four treatments was 42 ± 5·1 t/ha/annum.It was observed that the dry-matter yield of the three mixtures in J, K and L, containing the tall grass species, was significantly superior to that of treatment H; however, they were not statistically different among themselves.After the second year of grazing Stylosanthes gracilis diminished gradually and it was almost absent from the swards by the final year of grazing, while Centrosema pubescens maintained its stand throughout the experimental period.With the exception of phosphorus and sodium, levels of mineral elements in the pastures were above the recommended allowances for various classes of livestock.The average level of zinc was only slightly below the recommended value.

SUMMARYThe organic-matter intake and the digestibility of grazed tropical pasture mixtures were assessed by the chromic oxide-faecal organic matter-nitrogen technique in five digestion trials. The pasture treatments were designated as: H, Cynodon nlemfuensis var. robustus in a mixture with the legumes Centrosema pubescens and Stylosanthes gracilis; J, Pennisetum purpureum in a mixture with the two legumes in H; K, treatment J plus Panicum maximum; L, a mixture of all the grass and legume species in treatments H, J and K.The mean organic-matter digestibility of the herbages was determined in indoor digestion trials during the experimental period and varied from approximately 60·0 ± 1·73% to 62·7 ± 4·18% in treatments K and H respectively, with treatments J and L falling between these two values. The mean digestibility of the herbage as grazed, however, was approximately 66·8 ± 1·72, 69·7 ±7·68, 67·1 ± 4·40 and 67·4 ± 4·15 % for treatments, H, J, K and L respectively.The estimated mean intake of organic matter was somewhat lower, while that of the digestible organic matter was appreciably lower than those reported for animals of corresponding live weights in temperate countries. Grazed pastures were better digested by 4·1 digestibility units in treatment H, by 7·1 in both J and K, and by 5·3 units in L, compared with the indoor digestion trials.More intensive studies are still needed to warrant any justifiable conclusion as to whether the low intake of herbage by tropical cattle is due primarily to the high crude fibre and the low nutritional values of the pastures, or to the inherent capacity of the animals conditioned to grazing poor·quality pastures.

Four grass species namely: Cynodon nlemfuensis var robustus (M); Pennisetum purpureum Schum (N); Cynodon nlemfuensis var nlemfuensis (P); and Panicum maximum Jacq. (Q), each between the 4th and 5th, 6th and 7th, and 8th and 9th week of regrowth, was cut in the fourth and fifth years of grazing for hay (i. e. in 1972 and 1973). Digestion trials with West African dwarf sheep showed that there were significant differences in the extent to which the dry matter of the different grass species was digested (P 0.001) and among the stages of growth (P 0.01). The differences between animals within and between treatments and the interactions between treatments and periods of cutting were statistically not significant. The differences among treatment means indicated that treatment Q (68.5 ± 2.73%) was digested better than treatment M (54.9 ± 7.18%, P 0.001), and treatments N and P (60.3 ± 5.37% and 58.7 ± 5.30% P 0.01) respectively. The digestibility of crude protein was generally low in each of the grass specie studied. This is probably a reflection of the low crude protein content of the grass hays which was below 9 percent of dry matter. It ranged from approximately 27.3 percent in treatment N for the 6th week regrowth hay to 51.9 percent in treatment Q for the hay harvested in the 8th week of regrowth. The differences among treatments, stage of maturity, and the interactions between treatments and stage of cutting were not statistically significant. Significant differences between treatments were observed in the digestion of the energy content of the feeds (P 0.001). Treatments N and Q were better digested than M and P (P 0.05). Expressed on metabolic size basis, the intakes of dry matter, crude protein, and energy showed significant differences between treatments and between ages at harvest. The intakes of dry matter in treatments Q, M, and P were significantly higher (P 0.05) than treatment N while there was more dry matter taken from the 4th and 8th week hays than from the hays made from the species harvested in the 6th week of regrowth (P 0.01). More crude protein was consumed per kg0.75 in treatments M, P and Q than in treatment N (P 0.01), and in treatment M than Q (P 0.05). There were higher protein intakes from hays made in the 4th and 8th than those made in 6th week of regrowth (P 0.05). Treatment Q supplied more energy per kgl. 75 than treatments M, P and N (P 0.05), while more energy was consumed per kilogramme of metabolic size in treatment P than in treatment N (P 0.05). Nutritive Value of Hay. The intake of digestible crude protein was relatively low and this probably accounted for the losses in the liveweight of the experimental animals. The results of the experiment are suggestive of the need for supplementary protein feed during the dry season if animals are to make any liveweight gains.

An experiment was conducted to determine the effects of including legume species (Leucaena leucocephala, Stylosanthes guianensis, Centrosema pubescens Benth or Neonotonia wightii) at levels of 0, 5, 10, 20, and 40% of the dry matter on the chemical composition (crude protein, CP neutral detergent fiber, NDF; acid detergent fiber, ADF) and on in vitro dry matter digestibility (IVDMD) of mixtures of each legume with four grass species (Cynodon nlemfuensis Vanderyst, Panicum maximum jacq., Pennisetum purpureum Schum., or Sorghum bicolor (L.) Moench). Of the legume species included, Leucaena leucocephala and Centrosema pubescens had the highest CP content and IVDMD, respectively. For the legumes, the mean CP and IVDMD values, respectively, were Leucaena leucocephala, 21.98 and 68.09; Stylosanthes guianensis, 13.70 and 63.44; Centrosema pubescens, 18.29 and 68.60; and Neonotonia wightii, 16.72 and 66.64%. For the grasses, they were, respectively, Cynodon nlemfuensis, 8.27 and 61.38; Panicum maximum, 7.64 and 60.06; Pennisetum purpureum, 8.02 and 53.47; and Sorghum bicolor, 7.57 and 59.62%. Neutral detergent fiber and ADF contents were higher in the grasses (Cynodon nlemfuensis, 73.03 and 44.45; Panicum maximum, 65.27 and 49.06; Pennisetum purpureum, 69.26 and 51.88; and Sorghum bicolor, 60.24 and 50.99%, respectively) than in the fegumes (Leucaena leucocephala, 50.52 and 28.50; Stylosanthes guianensis, 52.57 and 36.63; Centrosema pubescens, 58.43 and 34.84; and Neonotonia wightii, 54.11 and 33.23%, respectively). The chemical composition of the forages varied according to the relative proportions of the species included, as expected. However, the effects on IVDMD were not additive; rather, associative effects, mainly antagonistic, were observed in most of the mixtures.

Forage is a ruminant animal basal feed, where sufficient and continuous availability and good quality must be a priority. Place to growth or location, also determine the existence and production of forage including grass species in this study. This study aims to determine how much the production of elephant grass, panicum and cetaria on salinity differences. The study was conducted for 4 months, in Kompleks Perumahan dosen UNIPA Amban in Manokwari West Papua. The study was designed with a split plot design in to Completely Randomize design (CRD) 4x3 with 4 replications. As the main plot is grass species and the subplot is salinity based on growing media. Factor I is grass species (Sp) consisting of: Pennisetum purpureum (Sp1), Panicum maximum (Sp2) and Setaria spacelata (Sp3) and then Factor II is growing media (M) consisting of: soil 100% (M0), soil 70% + 30% of sand (M1), soil 50% + 50% of sand (M2) and soil 30% + 70% of sand (M3). Statistical analysis shows that the effect of salinity is significant (P<0.05) on plant growth variable, namely fresh matter production, dry matter production and stem leaf ratio. Planting media M1 (soil 70% + sand 30%) perform the best result, and species that is responsive to salinity is Panicum maximum (Sp2).

This research aimed to evaluate the maize grain yield and forage of grass species under intercropping system using nicosulfuron herbicide. In order to assess the parameters related to maize, a randomized block design was defined. The treatments were arranged in a (5 × 2+ 1) × 2 factorial design with four repetitions resulting in 11 treatments, where maize was cultivated under intercropping condition with different forage species (5) (Brachiaria brizantha cv. Marandu, Piatã, Xaraés, Brachiaria ruziziensis and Panicum maximum cv. Mombaça) and maize monoculture (1) as control treatment, with and without nicosulfuron herbicide application (2) in two growing seasons (2014 and 2015). The off-season intercropping of maize with tropical forage grasses with and without herbicide suppression decreased maize grain yield. The suppression with nicosulfuron herbicide decreased the dry matter production of forage grasses. Intercropping of P. maximum cv. Mombaça with maize showed higher decrease in maize grain yield. On the other hand, it showed higher forage grasses production for livestock feeding. B. brizantha cv. Piatã was the forage which less affected maize grain yield under intercropping, even with absence of nicosulfuron suppression. Off-season maize under intercropping with tropical forages can be used to recover degraded pastures; increasing forage dry matter production for livestock, remaining the soil covered with straws with possibility of no-till seeding for the next cultivation.

The chemical composition of the leaves of three trees, Acioa baneri, Anacardium occidentale (Cashew) and Mangifera indica (Mango) and an herb, Aspillia africana (Hemorrhage plant), their dry matter intake (DMI, g/day) and digestibilities (%) of dry matter (DM), organic matter (0M), crude protein (CP) a crude fibre (CF) were determined in West African dwarf goats. The chemical composition of three grass species, Andropogon gayanus (Guinea grass), Cynodon nlemfuensis (Giant star grass) and Panicum maximum (Guinea grass was also determined to compare with those of the browses. The browses had higher CP (8.1-31.3%), acid detergent lignin (6.9-15.1%), Calcium (0.5-2.3%) and lower CF (9.6-23.5%) than the grasses which had 3.2-4.9% CP, 4.3-8.1% lignin, 0.43- 0.53% Ca and 24.4-28.1% CF. The consumption of fresh forages (g/d) varied from 193 on Acioa baneri to 918 on Aspilia africana. The highest DM intake was obtained on Aspilia africana, Apparent digestibility values (%) were: DM, 59.9&69.7; OM, 61.0-71.1; CP. 40.9-68.2 and CF, 39.3-64.9. Acioa batereri was the least digested of the forages. The higher CP content of the browses and their availability and acceptability by goals during the dry season in contrast 10 the low CP of the grasses indicates their potential for feeding goats. Acioa barteri is unsuitable as sole food for goats

The objective of this study was to evaluate milk yield and composition, dry matter intake, and stocking rate in pastures with tanzania grass (Panicum maximum cv. Tanzânia), star grass (Cynodon nlemfuensis cv. Estrela-Africana), and marandu grass (Brachiaria brizantha cv. Marandu). The grasses were managed in a rotational grazing system with Holstein x Zebu crossbreed cows, with a 30-day resting period and three days of paddock occupation. The pastures were fertilized with 1,000 kg/ha/year using the 20:05:20 (NPK) formula, split in three applications during the rainy season. It was used a complete random block experimental design with three factors being studied and two replications. In the experiment, four cows/paddock were used and, when it was necessary, regulator animals were added in order to obtain a supply of 7% body weight green forage dry matter. The animals were individually fed concentrate at 2 kg/day during the experimental period. Milk yield did not differ among the three grasses, with values of 9.1; 9.1; and 8.7 kg/cow/day for pastures with tanzania grass, star grass and marandu grass, respectively. Similarly, grass did not affect milk chemical composition. Stocking rate was similar among the three grasses, with values of 4.6; 4.5 and 5.0 UA/ha for tanzania grass, star grass and marandu grass, respectively. The highest dry matter intake was observed for tanzania grass with 2.6% of the body weight while stargrass (2.3%) and marandu grass (2.4%) did not differ among each other. The highest dry matter intake on tanzania grass pasture was not reflected on milk yield per animal. Milk yield and composition and stocking rate are similar among the evaluated grasses.

This experiment aimed to assess the recovery of infective larvae (L3) of Trichostrongylus colubriformis from Brachiaria decumbens cv. Australiana, Cynodon dactylon cv. Coast-cross and Panicum maximum cv. Aruana. The experimental module comprised six plots, with two plots per herbage species. Larval survival was assessed from autumn to winter, under the effect of two herbage-paring heights (5 and 30 cm). TThe paring was carried out immediately before contamination with faces containing T. colubriformis eggs. The feces and herbage were collected at one, two, four, eight, 12 and 16 weeks after feces had been deposited in the experimental plots. In general, larvae were recovered from both herbage and feces until the 16th week. The longer persistence of these larvae in the environment was probably due to warmer temperatures. The number of L3 recovered from the pasture was not influenced by the height of plants, except for Brachiaria and Aruana herbage in the fourth week. Regarding the concentrations of larvae per kg of dry matter (L3/kg DM), recovery was higher from low pasture in all three herbage species. During the autumn, the development and survival of the T. colubriformis free-living stages were not affected by the different herbage species.

ABSTRACT: The use of herbicide underdoses allows minimizing the competition of grasses on annual crops, enabling simultaneous cultivation. In this context, the objective of this study was to investigate glyphosate underdoses on the suppression of the initial growth of three Panicum maximum cultivars aiming at the integrated cultivation, in addition to the effects of forage species on the incidence and development of weeds. Three field experiments were conducted. The experimental design was a randomized block design with four replications and eight treatments consisting of increasing glyphosate doses (0, 54, 108, 270, 378, 540, 756, and 1,080 g a.e. ha−1). An atrazine dose of 1,200 g a.i. ha−1 was added to each treatment. Plant phytotoxicity assessments were performed at 7, 14, 21, and 28 days after application. At 80 and 125 days after sowing, the assessments of total dry matter production, leaf dry matter, stem dry matter, and leaf to stem ratio were carried out, in addition to density and dry matter production of weed community. Glyphosate underdoses below 215, 65, and 90 g a.e. ha-1 have a potential to be investigated aiming at the management of P. maximum cv. Atlas, P. maximum cv. Mombasa, and P. maximum cv. Tanzania under intercropping. The three forage species are effective in suppressing weeds.
