Abstract:

Research has been conducted to evaluate the effect of concentrate feeding technology on nutrient digestibility in Latvian Dark-Head lambs. Twenty-four purebred Latvian Dark-Head lambs (rams) were divided into three study groups (four lambs in each group). Concentrate was offered with different feeding technologies: group 1 – ad libitum once per day (ADL); group 2 – five times per day (5TD); group 3 – three times per day (3TD). Lamb live weight at the start of research was 24.6 kg (ADL), 24.1 kg (5TD) and 25.6 kg (3TD), the average age – 83 ± 1.4 days (ADL; p < 0.05), 75 ± 1.4 days (5TD) and 75 ± 1.6 days (3TD). Research data were collected over three periods and two repetitions during lamb fattening in July, August and September, 2019. During the data collection period lambs were transferred to cages with slatted wooden floor and a container with a grid under it. The highest concentrate intake in all data collection periods was found in ADL lambs (1.25 ± 0.106 kg – 1.75 ± 0.092 kg on average per lamb). Hay intake was not equal (90–350 g in average per lamb).The highest average faecal production was found in 3TD and 5TD lambs (F – 0.98 ± 0.102 kg (3TD), S – 1.13 ± 0.060 kg (5TD) and T – 0.99 ± 0.070 kg (5TD)).The least urinal production was found in 3TD lambs (0.24 ± 0.038 kg (F), 0.61 ± 0.078 kg (S) and 0.47 ± 0.033 kg (T)). Dry matter digestibility was 66.54–80.39%. Faecal consistency was soft for ADL and 5TD lambs and solid for 3TD lambs.

Abstract:

Milk production is increasingly modernized as a result of the growing demand for food around the world. Improvements in livestock facilities are observed, with a large increase in the use of feedlot systems such as the Compost Dairy Barn. Increasing milk production in confinement systems has also raised concerns such as the management of wastes (water, faeces and urine) from the system, which has become one of the most important issues in the intensive dairy farms. The aim of this work was to estimate the amount of manure present in compost dairy barn systems in order to size the manure storage. The study was conducted at four compost dairy barns in southern Minas Gerais, Brazil. These compost barns had different bedding materials and dimensions. In each farm, data on milk yield and quality (daily production, fat and protein content), animal weight and amount of feed ingested by the animals were collected. Total-day manure delivered by the cows in the feeding alley and milking parlour was piled up together and weighed. Based on the results, it was observed that, in the compost dairy barns, only part of the total manure produced per day was delivered in the milking parlour (1.6 and 2.0%) and in the feed alley (27.6 to 49.3%). These results are very important for designers for the proper manure management system design of the dairy farms.

Abstract:

Animal waste products, manure, in particular, are the sources of gases harmful to human and animal health. Hydrogen sulfide (H2S), which is produced from the breakdown of organic matter in animal faeces, is one of them. Its concentration in the cow barn air should not exceed 5 mg m−3. A special laboratory setup was designed and the level of hydrogen sulfide emissions from the cow manure was determined depending on the time and manure temperature and moisture content. The most intensive emission of hydrogen sulfide from manure was in the first 24 hours – the increment of H2S concentration was 0.168 mg m−3 per hour average. During the next 24 hours, it was 0.021 mg m−3 per hour. When the manure temperature increased, H2S concentration increased also; when the temperature manure decreased, H2S concentration decreased also. In 48 hours, the hydrogen sulfide concentration was 1.1 mg m−3 at the manure temperature of +3.0 °C. At the manure temperature of +23.4 °C and 21.3 °C, H2S concentration was 6.53 mg m−3 and 4.97 mg m−3, respectively. The higher was the manure moisture content, the lower was the emission of hydrogen sulfide into the environment. After 24 hours under the manure moisture content of 88.5% and 92.5% and its temperature of 21 °С ± 0.3 °С, the difference in the hydrogen sulfide concentration was 1.18 times depending on the manure moisture content. The selected regression equations described the dependence of the hydrogen sulfide concentration on the considered factors. The determination coefficients and Student’s criteria proved the reliability of the results obtained at the significance level P ≤ 0.05.

Abstract:

Odours released during the land application of manure results from different gases released from the liquid phase. These gases do create objectionable odours in the vicinity of the land-applied manure. In order to reduce the intensity of odour during manure application, we investigated the effectiveness of combining Borkohle with manure during land application.
Boracic acid is widely used as a flame retardant in cellulose insulation. During demolition of existing buildings, this insulation is sorted into its own residual waste fraction. The cellulose fibres are extracted and pelletized on site. Subsequently, the pellets are charred in a pyrolysis furnace. The resulting Borkohle – charcoal containing boron in various compounds – can be used as a soil enhancer and provides the trace element Boron to the fields. Furthermore, Borkohle provides long-term storage of carbon in the soil. Initial trials of combining boracic charcoal with manure additionally showed that odour emissions seemed to be significantly lower when manure was combined with Borkohle.
This work presents methods to quantify the odour reductions resulting from the addition of Borkohle to manure as well as first results. Parameters like the influence of the amount of charcoal added and exposure time have been investigated.
Charcoal was added at concentrations between 5 and 250 g L-1. While applying typical amounts of charcoal, a reduction of odour concentration of up to 85% was observed. A positive correlation between odour reduction and the amount of charcoal added was observed. Charcoal has a negligible effect when exposure times are less than 30 minutes.

Abstract:

An 8–week experiment was conducted to study the effect of adding phytase (Natuphos® 5000 BASF) to low and normal available phosphorus diets of laying hens on the excreta content and excretion of Ca, Mg, Zn and Cu. A total of 144 Hisex Brown laying hens that were 22 weeks old at the start of the experiment were randomly assigned to four dietary treatments. Treatments included three replicates (12 hens each) or 36 hens per treatment in total. Four corn-soybean meal-based diets were formulated to contain two levels of available phosphorus (AP; 0.12 and 0.46%) and two phytase levels (0 and 600 FTU kg–1). The results showed that there was no significant effect of added phytase on excreta Ca and Mg content (P > 0.05), but there was a significant effect of the dietary treatment on the content of Zn (P = 0.0075) and Cu (P = 0.0002). In terms of the excretion of these minerals, the dietary treatment had no effect on Ca and Zn excretion and a borderline effect (P = 0.0522) on Mg excretion measured as the amount of the mineral excreted per egg mass produced is observed. The results however showed a very strong effect of all three factors (available phosphorus, phytase and their interaction) on Cu excretion. The results indicate that adding 600 FTU to the corn-soybean meal laying hen diet with 0.12% or 0.46% AP beneficially affects the content and the excretion of Ca, Mg, Zn and Cu. Therefore, we can conclude that a laying hen diet containing 0.12% available phosphorus and 600 FTU during the first production cycle may not only satisfactorily support hens’ performance but will also beneficially affect the environment.

Abstract:

In accordance with the international and EU aims to reduce emissions of ammonia and other air pollution substances farm manure management, including its storage, especially for the animal breeding sector, is one of the most essential stages. One of the preventing steps is covering of the slurry lagoons. The most effective – hard covering can be provided only after the lagoon is constructed. The aim of the research: to develop methodology for calculations of emission reducing lagoon design volume and surface area. In the result of the theoretical research the possibilities of reducing the reflection surfaces at the same capacity of the lagoon have been discovered, as well as the changes of the reflection surface area, if instead of one lagoon several lagoons with less volume are installed and sequential filling of these lagoons is ensured. The article presents the calculation algorithms obtained during the research and recommendations for construction of low emission lagoons.

Abstract:

Methods for calculation of the amount of manure from every agricultural animal species and subgroup for production of biogas have been developed in compliance with the 2006 IPCC Guidelines. These methods can be applied for future forecasts if the amount of biogas produced in the country increases. It has been stated that in 2013 in Latvia for production of biogas mostly chicken and pig manure was used – correspondingly 33.7% and 26.7% from the amount of manure obtained from these animals. In the forecast for 2020, in turn, it is expected that the consumption of manure will be 31.9% of chicken manure and 31.5% of pig manure, from the amount of manure obtained from the corresponding group of animals.

Abstract:

Lake sediments as a potential fertilizer were studied at the Voke Branch of the Lithuanian Institute of Agriculture during 1994–2004. The aim of the research was to establish the influence of lake sediments and their mixtures with other organic matter (manure, sewage) on the crop yield and soil agrochemical and physical properties; to compare the effect of sediments with that of a sediment-manure mixture.Experimental evidence suggests that lake sediments had no effect on soil acidity. Thehigher rate of sediments (100 t ha-1) increased the content of total nitrogen in the soil by 0.002–0.021 and humus by 0.53 percentage units. Application of lake sediments had a positive impact on the quality of physical properties of sandy loam Cambisol. Various rates of sediments increased the soil moisture content and porosity, and declined soil bulk density. The rate of lake sediments 50,100 t ha-1 increased the productivity of crop rotation by 8–30%, manure – by 21–25%. Fertilization with lake sediments at a rate of 100 t ha-1 and pure manure produced 25–30% of the yield of energy units per year.

Abstract:

Soil fertility is influenced by different forms of land use. In a field trial (Western Lithuania, Vezaiciai branch of the Lithuanian Agriculture Institute) two manure rates (40 t ha-1 and 60 t ha-1) were introduced in acid and limed soil. The mineral fertilization in both acid and limed soil was the same: N60P60K60 for cereals, N120P90K150 for forage beet, N40P60K60 for barley with undercrop, P60K90 for perennial grasses in the 1st usage year, N60P60K90 for perennial grasses in the 2nd usage year. It was revealed that the long-term manuring and liming combination had a positive effect on moraine loam Dystric Albeluvisol fertility. Application of manure in acid and limed soil increases the nutrient stocks in the rooting zone of crops, increases pH value, amount of organic carbon and thus improves the topsoil structure. Long term manuring at rate 60 tha-1 resulted in the highest amount of mobile phosphorus (329 mg kg-1) in limed topsoil. The amount of mobile aluminium was reduced from 112.9 to 16.6 mg kg-1 if manure at a rate of 60 t ha-1 was applied. The combination of liming and fertilization ensure soil chemical indicators at the optimal level for more plant growth.

Abstract:

Details of the field experiments which were carried out in the Kazliskiai organic farm from 1999–2001 were needed for our investigations. The integrated evaluation method enabled us to make complex evaluation of the influence of catch crops (red clover, common ryegrass, white mustard and winter rape) for green manure and animal manure on spring barley agrocenosis in organic farming. The variances of the 11 indicators were subdivided into scales of 9 points. The resulting evaluation points were marked in a network diagram. The evaluation threshold, which is equal to 5 points, was also marked. The integrated evaluation index, consisting of the average of evaluation points, its standard deviation and standard deviation of the average of evaluation points which are below the evaluation threshold, was calculated. The influence of red clover for green manure on barley agrocenosis, according to the calculated integrated evaluation indices, is stronger than that of other catch crops and manure.
