The study was aimed to observe the nutritive value of concentrate used in different dairy farms at peri-urban areas of Chittagong, Bangladesh. Ten (10) different concentrate feeds were randomly selected from ten different farms which analyzed for moisture, dry matter (DM), crude protein (CP), crude fiber (CF), nitrogen free extracts (NFE), ether extracts (EE), total ash (TA) and acid insoluble ash (AIA) and requirements of concentrate for unit production of milk was calculated. It was found that the nutritive value of individual feed concentrate of each farm varied significantly. The observed proportion of using feed ingredients was also significantly different among the farms. Finally, it may be summarized that the concentrate mixture used by the different farmers of peri-urban areas of Chittagong was different in regards to chemical composition, ingredients and amount required for milk production.

Green Fodder

The aim of this paper is to study the chemical composition of a green fodder used in laying hens feeding raised in ecological system; organic fodder being an important condition to obtain organic eggs for consumption. In order to evaluate the chemical composition variations of the green fodder throughout the year, there were taken plants samples in three different vegetation stages (May, September and October). To each period, were done 5 determinations for the following indicators: dry matter - DM (%), ash - Ash (%), crude protein - CP (%), ether extract - EE (%), crude fiber -CF(%), nitrogen free extract - (NFE%) calcium � Ca(%), phosphorus - P(%), magnesium - Mg (%), natrium -Na(%). And also, were analyzed the relevant indexes for the organic production: lead -Pb (mg/kg DM), cadmium - Cd (mg/kg DM), cooper -Cu (mg/kg DM), zinc - Zn (mg/kg DM) nitrites (ppm), nitrates (ppm), pesticides. After analysis, it was noticed that dry matter, minerals, organic matter and protein content varied very significantly between the first period and the third (p �0.001), while the fat content, crude fiber and nitrogen free extract did not register significant differences (p �0.05). Regarding the minerals elements analyzed, P and Mg differed significantly distinctly between the first and the last analyzed period. The content of green fodder in Pb, Cd, Cu and Zn was below the limits allowed by current legislation. The analyses for pesticides have highlighted the lack of them in the fodder. The quality parameters of the analyzed green fodder, expressed through levels of pollutants such as heavy metals, nitrites, nitrates, pesticides, allow us to notify that the green fodders achieve the conditions necessary for organic production.

Feeding Value

The present investigation was undertaken with the object of ascertaining the effect of cutting at fortnightly instead of weekly intervals on the yield of pastures, and on the composition, digestibility and nutritive value of the herbage.The main trial was carried out on the 1925 light-land pasture. The plot was divided into 14 sub-plots, and one sub-plot was mown per day. The whole plot, therefore, was cut over once per fortnight during the season. The results in respect of yield, composition and nutritive value were compared with corresponding results obtained on the same pasture plot under a system of weekly cuts during 1925.A second trial was carried out on sub-plots 2 and 3 of the 1926 heavy-land pasture, one sub-plot being cut weekly and the other fort-nightly. The work in this case was restricted to securing comparative data in respect of yield and composition of herbage.The results from both trials lead to the conclusion that the differences in chemical composition, both organic and inorganic, between pasture grass cut at weekly and fortnightly intervals are inconsiderable. The dry matter of the fortnightly-cut grass is extremely rich in crude protein and contains, in comparison with grass cut at the hay stage of maturity, a low percentage of crude fibre. Moreover, these characteristics are retained, by systematic cutting at fortnightly intervals, over the entire season.The results of the digestion trials justify the conclusion that the dry matter of the pasture herbage grown under a system of fortnightly cutting is a protein concentrate equal in digestibility and nutritive value to that obtained by weekly cutting. There is no significant running off in respect of composition and feeding value during the second week of growth. At the end of a fortnight the herbage still consists of the same immature, non-lignified. tissue as it was at the end of a week's growth.

The chemical composition and the utilization by domestic goats (Capra hircusL. ‘Saanen’) of alfalfa (Medicago sativaL.) hay and silage that contained or did not contain hoary alyssum [Berteroa incana(L.) DC. ♯ BEFIN] was studied. Alfalfa was higher in quality than hoary alyssum; crude protein (CP) was 38% higher, and the neutral- and acid-detergent fiber (NDF and ADF) were 18 and 29% lower, respectively. Less CP and more ADF were found in weedy hay than in other forages. Animal utilization, as measured by the dry-matter intake, digestible dry-matter intake, relative intake, and nutritive value index were greater for weed-free than for weedy forages. Hoary alyssum was more deleterious in chopped silage than in long hay, because of selective refusal of the weed by goats that were fed hay. The presence of hoary alyssum in alfalfa decreased its utilization by ruminants.

ABSTRACT Feed shortage during the dry season in the highlands of Madagascar negatively impacts the dairy cattle productivity, as well as the farmers’ income. Bamboo can produce a high quantity of biomass and could be an alternative way to increase the fodder supply for cattle. The present study aimed to assess the compositional information and the optimal rate of bamboo as fodder for dairy cattle. Leaf samples from nine bamboo species were collected to determine their chemical composition and nutritive value. A feeding experiment was also conducted using ten dairy cows, over ten weeks. Bamboo leaves were mixed with maize silage in five proportions: SIL0:BAM100, SIL25:BAM75, SIL50:BAM50, SIL75:BAM25 and SIL100:BAM0. The contents of dry matter, total ash and crude protein in the bamboo leaves were, respectively, 44.5-64.6 %, 6.68-18.5 % and 7.71-15.4 %. In the feeding trial, the dry matter intake of bamboo leaves was 1.6-7.1 kg per day, with an average of 4.8 kg per day. The dry matter apparent digestibility of bamboo leaves was 37.4-56.4 %. The milk production reached 13.6-14.4 L per cow, per day, but there was no significant difference concerning the rate of bamboo leaves in the mixed diet (p > 0.05). The introduction of bamboo leaves into the ruminants diet did not affect their milk production.

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.

Silage Quality

A survey was made on 31 dairy farms of the botanical and chemical composition of pasture being ensiled and of the chemical composition of the resultant silages. Despite the wide range in grass (37-100s) and legume (O-SO%) components, drymatter content (20-56v/o), soluble carbohydrate (4-19s) and neutral detergent fibre (NDF) (43-69%) contents, NDF was the only component significantly correlated with dry matter digestibility (range 53-76%) (r = -0.77; P > 0.01). Wilting time ranged from 2-47 hours except in seven of the silages which were not wilted. Four silages were not covered with polythene but were similar in chemical composition to other silages when sampled in summer. Phosphorus (P) (.lS-.42% DM) and nitrogen (N) (l.O-2.2% DM) in silage were below published requirements for cows in mid lactation in more than 75% of the silages. It is suggested that either or both of these minerals may limit milk production from cows fed a predominantly silage ration during summer. Ensiling of less-mature pasture is advocated to ensure a more digestible feed which is likely to contain adequate levels of P and N.

The present paper deals with the composition and nutritive value of the following by-products of the pea-canning industry: (1) green pea pods; (2.) pea-pod meal resulting from the artificial drying of pea pods; (3) pea-pod silage as made in a tower silo; (4) molassed silage made in a sisalkraft silo from pea haulms with pods.Pea pods give rise to an excellent silage provided they are tightly trampled and a means for draining off the effluent is supplied. The silage is pale yellowish green in colour and has a pleasant, vinegary smell with little or no suggestion of the presence of butyric acid. It is much relished by sheep and cattle. It is superior in digestibility to ‘green fruity’ oat and vetch silage and contains, per 100 lb., 27·5 lb. of dry matter, including 15·9 lb. of starch equivalent and 2·3 lb. of digestible crude protein. No molasses need be added during filling, since the sugar naturally present in the pods ensures a favourable fermentation.

The objective of this study was to evaluate the effect of different doses of liquid swine slurry on dry matter accumulation rate and nutritive values (crude proten and neutral detergent fiber) of Tifton 85 grass pasture cultivated in southwestern Paraná from October 2005 to March 2006. It was used a complete random experimental design in a 4 x 4 factorial scheme composed of four doses of swine slurry in the plots (0, 80, 160 and 320 m³/ha) and four consecutive cuts in the subplots of the pasture. It was carried out two applications, one in the beginning of the experiment and other after 80 days. Cuts were performed every time pasture height was 40 cm. There was a dose versus cut interaction for all variables. Swine slurry promoted increase on dry matter accumulation rate only on the first cut after its application (cuts 1 and 3). Dry matter maximal yield (24.2 t/ha) was obtained at 249 m³/ha of swine slurry manure (143 and 106 m³/ha, respectively for applications 1 and 2), corresponding to 450 kg of N/ha. Percentage of crude protein increases and neutral detergent fiber of Tifton 85 grass decreases as dose of swine slurry increases, improving forage nutritive value. Use efficiency and nitrogen recovery rate decrease with addition of swine slurry doses.

The objective was to evaluate agronomically nine sorghum-sudangrass hybrids (Sorghum bicolor × Sorghum sudanense) and the nutritive value of their respective hays. The experimental design used was randomized blocks in a 3 × 9 factorial scheme, with three replications. Three cuts were made: 42 days after germination, 29 days after regrowth, and 28 days after the second regrowth. All hybrids showed a higher number of plants ha–1 (P < 0.05) in the second cut. For the green matter and dry matter production of the hays, the values ranged from 49.16 to 62.07 t ha–1 and 9.07 to 11.43 t ha–1, respectively. There were no differences (P > 0.05) in dry matter, mineral matter, or ether extract. The hybrids 1013020, BRS 810, 1013016, and 1624F016 showed higher values of crude protein (CP) of 16.49, 16.17, 16.08, and 15.88%, respectively. Differences were observed (P < 0.05) in neutral detergent fiber (NDF) content. The hybrids 1013020, BRS 802, 1013021, 1013016, BRS 810, and 1624F006 presented lower levels of NDF (60.57, 60.74, 62.15, 62.37, 62.58, and 64.70%, respectively). The hybrids BRS 802, 1013016, BRS 810, and 1624F006, stood out above the others, presenting high forage yield and adequate nutritive value (CP content >13% and NDF content <65%).

To evaluate the chemical composition of the earthworm (Eisenia foetida) co-dried (EW) with vegetable meals (VM) as animal feed ingredient, the blends were mixed with wheat bran (WB), rice powder (RP), corn meal (CM) and soy cake meal (SCM) in proportions of 85:15; 75:25 and 65:35. The dry matter (DM), crude protein (CP), crude fat (CFA), crude fiber (CF), ashes and nitrogen-free extract (NFE) of the ingredients and final mixtures were determined. All the mixtures resulted with a high content of DM (≥90.00 %). No significant differences among the proportions were revealed (P>0.05). In addition, the higher inclusion of the earthworm in the proportions (85:15) increased (P<0.05) the CP (54.70 %), CFA (7.28 %), and ashes (10.20 %), mainly when mixed with SCM, CM, and RP, respectively. However, the use of vegetable meals proportionally increased the CF (7.31 %), and NFE (52.62 %), mainly with the proportion of 65:35 and with RP and CM, respectively (P<0.05). The results showed that the vegetable meals (WB, RP, CM, and SCM) are useful to co-dry the earthworm to be use for animal feed. It is concluded that the most appropriate proportion (VM:EW) will depend on the animal species, productive stage and market requirement.
