Beef Feedlot Manure

Composting is increasingly recognized as a means of handling livestock manure. Using relationships derived from a dataset of >3000 samples representing the decay spectrum from raw manure to mature compost (from unpaved feedlot pens bedded with straw or wood residuals) we propose that measurement of either total carbon or ash content is sufficient to estimate carbon, organic matter and dry matter mass changes during composting of beef feedlot manure.

A research was conducted to evaluate the effects of concentrate utilization in Guinea grass (Panicum maximum) ration on dry matter and organic matter digestibilities. Twelve male local goats were used in this experiment and located in individual pens. Completely Randomized Design (CRD) with four treatments and three replicates was used. The treatments were R1 = 100 % guinea grass, R2 = 75 % guinea grass + 25 % concentrate, , R3 = 50 % guinea grass + 50 % concentrate, and R2 = 25 % guinea grass + 75 % concentrate. The results showed that effects on dry matter and organic matter digestibilities were high significantly different among treatments (P < 0.01). Ration without concentrate was significantly lower compared to ration with concentrate;. It can be concluded that the best dry matter and organic matter digestibilities were on 75 % concentrate in the ration Key words : Guinea grass, concentrate, digestibility, dry matter, organic matter, and local goats

Intake, digestibility, nitrogen retention and the effects of 2.6% soluble oxalates in the dry matter (DM) of kochia (Kochia scoparia (L.) Schrad.) were examined when beef steers were fed rations varying from 100 to 0% kochia hay and 100 - 0% bromegrass (Bromus inermis Lyess.)/alfalfa (Medicago sativa L.) hay. Plasma Ca, P, Mg, Zn, Fe and Cu concentrations were normal and not affected by supplementation with CaCO3. The organic matter digestibility (OMD) of kochia (55.4%) was less (P < 0.05) than that of the bromegrass/alfalfa hay (61.3%). However, in a second trial, OMD was not influenced if kochia was included at up to 60% of the ration. In a third trial, DM intake remained constant until 60% kochia was present in the ration but was reduced (P < 0.01), even with careful adaptation, when kochia exceeded 60% of the diet. Nitrogen retention declined (P < 0.05) as the proportion of kochia in the ration increased and was negligible at 100% kochia.

A study was conducted to identify adaptability, high biomass and dry matter and grain yielder of vetch varieties/genotypes at Bore Agricultural Research Center Adola sub-site. The three vetch varieties/genotypes tested were Vicia dasycarpa, Lalisa and 5187. Randomized complete block design (RCBD) with three replications was employed to evaluate the variety. The result revealed that date of 50% flowering, date of maturity, pod length per plant and plant height was significantly different (at p<0.05) between treatments. The early flowered genotype was 5187 (62 days) and late flowered variety was recorded from Vicia dasycarpa (79.9 days). The highest value of plant height was measured from Lalisa variety, while the shortest plant height was recorded from 5187 genotypes (67.7 cm). Date of 50% emergency, pod per plant, fresh biomass yield and grain yield and chemical composition dry matter (DM), crude protein (CP), neutral detergent (NDF), acid detergent lignin (ADL), acid detergent fiber (ADF), total ash content (TASH) and organic matter (OM) did not show significant difference between treatments at (P>0.05). Numerically had different values. Both the highest fresh biomass yield and grain yield was obtained from Lalisa variety (2.9 t/ha) and 22.7 qt/ha respectively. The lowest value of biomass and grain yielder was produced from 5187 accessions (1.9 t/ha) and Vicia dasycarpa 11.3 qt/ha. Lalisa variety was highest in organic matter (OM), total ash content (TASH), crude protein (CP) and less in neutral detergent (NDF) and acid detergent fibre (ADF) content while, Vicia dayscarpa was highest in crude protein (CP) and neutral detergent (NDF) and less in organic matter (OM), content total ash content (TASH) and crude protein (CP) content, 5187 genotype had the highest in dry matter (DM) and acid detergent fiber (ADF) and less in crude protein (CP) and acid detergent lignin (ADL) content than the rest accessions. The result of this study implied that Lalisa variety was well adapted and being productive regarding the plant height, biomass yield and seed yield. Lalisa variety, which is hopeful to fill the gap of low quantity ruminant feed supply of the community in the study area. Based on its adaptable, high biomass, high plant height, high grain yield, good CP and OM Lalisa is recommended for further promotion in the midland of East Guji zone.

Two experiments were carried out in order to study the effect of the ash content of poultry litter (PL) on its nutritional value. In Expt 1, broiler PL was incorporated in the proportions of 30 and 45% into diets based on wheat straw supplemented with 20% maize grain. The PL was either fresh (containing 19% ash) or had been heated in a stack (giving 26% ash). There were also two additional diets containing 45% fresh PL to which either ground limestone or wood ash had been added to provide the same ash content as the diets containing 45% stored, high ash PL. An in vivo digestibility and nitrogen balance trial was carried out. Storing the PL, which resulted in heating and an increase in ash content, reduced dry matter intake significantly. The largest and most significant effect on the digestibility of dry matter, organic matter and crude protein can be ascribed to the freshness of the PL. Stored, heated PL had a highly negative effect on crude protein digestibility and on nitrogen retention. No negative effect of adding extrinsic ash was recorded. In Expt 2, the nutritional value of layer PL (LPL), compared with that of broiler PL (BPL), was examined using ten beef cows before and after calving. The diet was composed of 45% PL, 35% wheat straw (WS) and 20% maize grain. Daily dry matter intakes were 12·7 and 16·2 g/kg liveweight (LW) before calving and 15·5 and 22·8 g/kg LW after calving, for cows fed LPL and BPL, respectively. Owing to the combined effect of the lower dry matter intake, lower gross energy content and lower digestibility of LPL, the digestible energy intake of BPL diets was almost three-fold, and nitrogen absorption (g/kg LW0·75) on the BPL was 2·4-fold higher than on the LPL diets. Because the ash intake of both diets was similar, it is suggested that the main inhibiting factor of intake after calving was the rumen's ability to mobilize the large amounts of ash-rich complexes of ash and organic matter to the reticular omasal orifice and, consequently, out of the rumen.

Neural image analysis is commonly used to solve scientific problems of biosystems and mechanical engineering. The method has been applied, for example, to assess the quality of foodstuffs such as fruit and vegetables, cereal grains, and meat. The method can also be used to analyse composting processes. The scientific problem lets us formulate the research hypothesis: it is possible to identify representative traits of the image of composted material that are necessary to create a neural model supporting the process of assessment of the content of dry matter and dry organic matter in composted material. The effect of the research is the identification of selected features of the composted material and the methods of neural image analysis resulted in a new original method enabling effective assessment of the content of dry matter and dry organic matter. The content of dry matter and dry organic matter can be analysed by means of parameters specifying the colour of compost. The best developed neural models for the assessment of the content of dry matter and dry organic matter in compost are: in visible light RBF 19:19-2-1:1 (test error 0.0922) and MLP 14:14-14-11-1:1 (test error 0.1722), in mixed light RBF 30:30-8-1:1 (test error 0.0764) and MLP 7:7-9-7-1:1 (test error 0.1795). The neural models generated for the compost images taken in mixed light had better qualitative characteristics.

AbstractExperimental results are brought together to demonstrate that forage kale population improvement involving full-sib and selfed families can be done on an annual cycle, followed by production of a synthetic cultivar. Furthermore, this new breeding method compares favourably with the two successful methods used to date, namely triple-cross hybrid cultivars from inbreeding and crossbreeding programmes and open-pollinated cultivars from population improvement programmes. The key findings were that natural vernalization of kale in south east Scotland occurred by mid-December so that plants could be pollinated in a glasshouse with heating and lighting by the end of February and seed harvested by the end of May. The resulting full-sib or selfed families could be assessed in a field transplant trial in the same year, from June to November, thus completing an annual cycle. Self-pollination resulted in shorter plants with lower fresh-weight, dry-matter and digestible organic-matter yields, and undesirably higher contents of S-methylcysteine sulphoxide, the haemolytic anaemia factor, and the goitrogenic thiocyanate ion. As a consequence of digestible organic-matter yield being reduced by as much as 22%, the estimated optimum number of selfed parents in a synthetic cultivar was four to eight. Synthetic cultivars are expected to yield as well as triple-cross hybrids as there was no reduction in yield when the latter were open-pollinated.

Whole barley was treated with sodium hydroxide (NaOH) in laboratory trials. Dry matter disappearance from nylon bags in the rumen of whole barley treated with 2.5, 3.5, or 4.9% NaOH for 30 h was 59.6, 72.4, and 93.0%, respectively, compared with 82.2% for untreated ground barley. In a subsequent lactation trial, 24 Holstein cows (eight per treatment) were fed high moisture ground ear corn, high moisture rolled barley or high moisture whole barley treated with 3.5% NaOH. Milk persistencies tended to be greater for cows fed high moisture rolled barley, next for ground ear corn and least for NaOH-treated barley. Milk composition was similar for all treatments. Dry matter intake was greatest for cows fed ground ear corn and lower for those fed the barley diets. Alpha-linked glucose and pH of feces were similar for cows fed ground ear corn and high moisture rolled barley diets, but fecal pH was lower and alpha-linked glucose concentrations three times greater for NaOH-treated barley. Digestibility percents of dry matter, acid detergent fiber and nitrogen were 61.4, 25.3, 64.7 for ground ear corn; 64.4, 38.0, 67.1 for high moisture rolled barley; and 56.8, 43.2, 54.8 for NaOH-treated barley, respectively. Rumen grain turnover estimated by excretion of ytterbium in feces was greatest for NaOH-treated barley (9.09%/h), intermediate for ground ear corn (6.10%/h) and lowest for high moisture rolled barley (4.93%/h).
