Wood molasses from sulphate spent liquor was tested as a preservative for high moisture barley. In Exp. 1 wood molasses was applied at levels of 8 and 16 % of barley dry matter (DM). In Exp. 2 an application level of 12 % was compared with AIV II solution used at a level of 3 l/1000 kg. Barley was rolled before ensiling and water was added so that the moisture content was 55 % in Exp. 1 and 55—60 % in Exp. 2. Digestibility and nitrogen retention in growing pigs, liveweight 31—81 kg, were determined for dried barley, propionic acid treated barley and barleys ensiled with AIV II or wood molasses (12 % of barley DM). In Exp. 1 the application level of 8 % unneulralized wood molasses (pH 2) was sufficient to prevent deterioration during storage. The preservative effect was based mainly on the acidity provided by organic acids. With the higher level of application the lactic acid content was lower (P < 0.05). In Exp. 2barley ensiled with neutralized wood molasses had a higher (P < 0.01) lactic and acetic acid content and a lower pH value (P < 0.05) than barley ensiled with AIV II. Wood molasses decreased protein breakdown during the storage. The effect of DM content on fermentation and proteolysis was greater for AIV II ensiled barley. During the storage the sugar content increased because of starch hydrolysis. DM, organic matter (OM), NFE and starch digestibilities were lower on diets of barley ensiled with AIV II and wood molasses than on dried barley diet (P < 0.05). OM digestibilities for the diets were 82.2, 81.0 and 85.4 %, respectively. The digestibility of barley treated with propionic acid was slightly lower than that of dried barley. No differences were found in nitrogen retention.

As unconventional forage source, mulberry (Morus alba L.) has been cultivated to alleviate animal feed shortages. This study aimed to investigate the effects of N fertilization during cultivation and Lactobacillus plantarum inoculation at ensiling on the chemical composition and bacterial community of mulberry silage. Mulberry was separately cultivated under two N fertilization rates (N1, 390 kg/ha/year; N2, 485 kg/ha/year) in 2016–2019, harvested on 30 April (the first-cut) and 15 June (the second-cut) in 2019, and then chopped for producing small bag silage. The silage was treated without (control) or with L. plantarum (LP, a recommended application rate of 105 cfu/g on fresh matter basis). After storage of 60 days in dark room at ambient temperature, silage was sampled for analysis of chemical and microbial compositions. Higher (P &lt; 0.05) final pH value and acetic acid content and lower (P &lt; 0.05) lactic acid content were found in silage of mulberry under N2 fertilization, resulting in more dry matter loss than that under N1 fertilization. Compared with control, inoculation of LP at ensiling increased (P &lt; 0.05) lactic acid content and decreased (P &lt; 0.05) final pH value, acetic acid and propionic acid contents of silage, by advancing the dominance of Lactobacillus and reducing the abundance of Enterococcus and Enterobacter. In particular, inoculation of LP at ensiling decreased (P &lt; 0.05) dry matter loss and butyric acid content of first-cut silage. In conclusion, inoculation of LP at ensiling could reduce the undesirable effects from high N fertilization rate during cultivation on silage quality of mulberry harvested at different growing seasons.

ABSTRACTGrowth and carcass traits were measured in pigs grown from 25 to 90 kg live weight on barley stored and prepared in different ways. Some of the barley was prepared in the conventional manner by drying to a moisture concentration of 140g/kg before hammer-milling. The remainder of the barley was rolled after treating batches, containing 140, 180 and 240 g moisture per kg, with propionic acid. A total of 128 pigs was used at three centres.There were no differences between the centres and no differences in the performance and carcass measurements of pigs given acid-treated and rolled, or untreated and milled barley, despite differences in physical form between the rolled and milled samples. When the intake of dry matter was equalized there was no apparent effect on the pigs of acid treatment of barley containing different amounts of moisture.

Abstract: This study evaluated the effects of varying amounts of melon with high sugar content offered to sheep without prior melon experience and that were not adapted to consuming it. We used 12 eight-month-old, rumen-cannulated crossbred sheep weighing 25 kg each. The animals received a base diet of roughage, and then half were randomly selected to have 25% of their diet replaced with melon (G25%) and the other half had 75% of their diet replaced with melon (75%). Ruminal fluid was collected before administration of melon and at 0, 3, 6, 12, 18, and 24 h after the administration of the fruit. Sheep from the G25% group presented volatile fatty acid ruminal acidosis (sub-acute) between 3 and 6 h after consumption. This acidosis was characterized by a rumen pH slightly lower than 5.6, increased discrete L-lactic acid content, and increased redox potential (RP) and methylene blue redox (MBR) time of the ruminal fluid. The G75% group presented lactic ruminal acidosis at T6h, characterized by a rumen pH lower than 5.0, high lactate-L content, increased RP and MBR time, and increased ruminal fluid osmolarity. Therefore, offering large amounts of melon (75% of dry matter (DM)) is not recommended but 25% of DM of this fruit can be used safely.

We analyzed the relationship to sour cherry quality parameters of average temperature, maximum temperature, minimumtemperature, night and day-time temperature, precipitation and climatic water balance variables. Three cultivars of sour cherry were includedin the selection: “Debreceni bôtermô”, “Kántorjánosi”, and “Újfehértói fürtös”.We conducted regression analyzes on the three varieties, butpresent only those that proved to be the best fit.We couldn’t find any significant differences in the weather tolerance of the varieties. The database of sour cherry quality parameters covers the 1998 to 2008 intervals. The researched parameters were the following: dry matter content(%), sugar content (%), C-vitamin (mg), total acid content (%). Maximum temperature, the difference of night and day-time temperature andminimum temperature all have a significant correlation with the investigated quality parameters of sour cherry. Minimum temperature showsa quadratic relationship with sugar content, while night and day-time temperature differences show the same with dry matter content. Theother weather parameters had a linear correlation with the quality parameters of sour cherry. The research results show that an increasingamount of precipitation causes decreasing tendency in total acid content of sour cherry, so that increasing temperature has a positive influenceon total acid content. Big differences in night and day-time temperature also has positive effects on the dry matter and sugar content of sourcherry while the amount of precipitation has a negative effect. High minimum temperatures cause decreasing sugar content respiratory energylosses are significant if dawn temperatures do not drop considerably.A more favourable climatic water balance has a positive effect on vitaminC content in cases of a large negative water balance, vitamin C content is generally low.

Feeding Value

SUMMARYForty-eight pigs were used to compare the feeding value of barley which had been stored dry, and then hammer-milled, with that of barley stored moist, either anaerobically or treated with 1·3% propionic acid, and then rolled. The pigs were fed from 30 kg live weight for a period of 11 weeks and during this period all consumed the same allowance of dry matter. The growth rate and feed conversion ratio of the pigs given the rolled moist barley were significantly poorer than those of others given dry milled or acid treated rolled barley. There were no treatment differences in carcass attributes.Microbiological counts made throughout the experiment showed that there was no significant fungal or bacterial development on the acid treated barley. Similar numbers of bacteria were present on the dry barley as on the moist, but the fungal count for the moist grain was always at least 500 times higher than that of the corresponding dry sample. The dominant organisms were identified.In a further experiment the apparent digestibility of dry matter and nitrogen of diets containing dry, moist or propionic acid treated barley, processed either by milling or rolling, were determined. The highest values were obtained for dry barley. Acid treated moist barley had lower values than moist barley. The method of processing did not affect the apparent digestibility of the dry matter, but that of the N was significantly lower for the rolled barleys.

SUMMARYA total of 156 pigs of the Large White breed were used in a series of four experiments to test the suitability of barley which had been stored with a high moisture content as an ingredient in the diets of growing pigs. Barleys with mean moisture contents of 26·3%, 28·1% and 21·2% and a range from 19·6% to 30·5%, from three successive harvests were used.In all the trials there was evidence that the use of moist barley in diets for growing pigs had an adverse effect on live-weight gain and feed conversion ratio, the effect being independent of whether feed intakes were equated on the basis of the dry-matter content of the diets. In one of the experiments performance was depressed to the extent of causing changes in carcass characteristics. The performance of pigs given rolled barley was similar to that of others given ground barley.

SUMMARYFeeding trials were carried out at different times of the year to determine the optimum crude protein requirements of weaner and growing pigs, using principally the locally available ingredients. The animals used were 96 weaners and 113 growing pigs of the Large White and Landrace breeds of average initial weights of about 9 kg and 41 kg respectively. Test diets contained protein levels ranging from 12% to 24% on a dry-matter basis, and the pigs were mostly group-fed ad libitum except for one trial. Average daily gains, efficiency of feed utilization, apparent nitrogen retention and digestibility, and feed cost per kg of body gain were measured. In a humid tropical environment, such as Ibadan, the optimum crude protein requirement for weaner pigs from 9 kg to 34 kg live weight is between 22 % and 24 % of dry matter, while that for the fattening pigs from 41 kg to 82 kg live weight is between 18% and 21% of dry matter.

This study aimed to evaluate the fermentation characteristics, losses and the chemical composition of two pearl millet genotypes silages submitted to nitrogen fertilization. The experimental design was a completely randomized blocks in a split plot scheme 2x5 (two nitrogen genotypes doses x five doses of nitrogen), with four replicates. Nitrogen doses were 0, 20, 40, 60, 80kg ha-1 and the pearl millet genotypes were the variety ADR300 and the hybrid ADR7010. The hybrid ADR 7010 showed average lactic acid content higher than the variety ADR 300, at all doses of N, recording values ranging from 4.09 to 10.46dag kg-1. There was an interaction between nitrogren doses and genotypes for the neutral detergent fiber, which ranged from 51.81 to 63.63dag kg-1 of dry matter. Dry matter recovery decreased linearly with increasing nitrogen doses only for hybrid ADR7010, the same did not happen for the ADR300. The nitrogen fertilization does not favor the fermentation characteristics and increases DM losses of the hybrid ADR7010.

The aim of this paper is to present technological characteristics of the Vranac and Cabernet Sauvignon grapevine varieties in the conditions of the Trebinje vineyards during the vegetation in 2016 and 2017. Researching technological characteristics includes mechanical compounds of grapes and berries as well as the quality of grapes and berries (sugar, total acid content in the must and pH). Bunch weight, the number of berries on a bunch, the weight of 100 berries, the weight of 100 berries flesh, the weight of berries skin as well as the weight of 100 berries seeds were higher for both varieties in 2017. The bunch weight of Vranac was higher in 2016, and for Cabernet Sauvignon in 2017. Sugar content and acid content were higher in the must of the Vranac variety in 2016, while its pH value did not vary. The sugar content of the Cabernet Sauvignon variety was the same in both examined years, the content of acids was higher in 2016, while the pH value was higher in 2017.

High Moisture Corn

Two trials, involving a total of 144 pigs, were conducted to evaluate the effect of corn moisture content and preservation of corn with propionic acid on performance. Treating of corn containing approximately 76% dry matter with 1.5% w/w of propionic acid and storing in bins open to air resulted in no apparent problems in terms of heating or mold growth during storage. Pigs fed high moisture corn gained at a similar rate and had a feed efficiency equal to or better than pigs fed dry corn (90% dry matter). The addition of propionic acid to corn fed to pigs in groups improved rate of gain. A total of 13 pigs in the two trials died due to hemorrhaging the cause of which is unknown, but death did not appear related to dietary treatment.
