Feeding Value

Studies of aerobic stability, digestion and growth performance were conducted with steers to determine the mode of action of a bacterial inoculant in altering the feeding value of ensiled high-moisture ear corn (HMEC); a comparison was made with propionic acid (PA) treated HMEC (10 g kg–1 fresh matter). The inoculant consisted of Lactobacillus plantarumand Enterococcus faecium, and was applied as an aqueous solution to provide 104 colony-forming units (cfu) per gram of HMEC. Inoculation of HMEC was not as effective as PA in improving aerobic stability, as assessed by changes in populations of yeasts and moulds. However, steers fed inoculated HMEC gained 11% more weight (P < 0.05) than animals fed untreated HMEC, and 9% more (P < 0.10) than those fed PA-treated material. There were no effects of treatment on food intake or digestion of organic matter (OM). At 4 h after feeding, rumen pH and molar proportions of isovalerate were greater (P < 0.05) with inoculated than untreated or PA-treated HMEC. Treatment differences in aerobic stability of HMEC did not account for the responses in growth performance. It appears that improvements in growth rate of beef cattle fed inoculated HMEC may be related to pH and/or the production of iso-acids in the rumen.

Soybeans at 18 and 22% moisture were treated and stored by adding 0.75% by weight of propionic acid. No heating was observed in the acid-treated beans during the 10-week storage period. Mold counts of the treated samples were much lower than the controls. The lack of fungal activity suggests that the probability of mycotoxin production during storage is very low. Propionic acid treatment almost eliminated the ability of the soybeans to germinate. Prior to treatment germination had been 96%. No significant shifts in fatty acid composition of the extracted oils were observed. Oil quality did not deteriorate after treatment with propionic acid. The data indicate that propionic acid can be used successfully to preserve high moisture soybeans.

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 Eastern goat’s rue (Galega orientales Lam.) possesses high fodder productivity and accumulates a large amount of vegetative mass with high humidity for harvesting for seeds. This greatly complicates the harvesting of grass stand for seeds. One of the ways to solve this problem is to carry out desiccation of the grass stand. A complicating factor in choosing the optimal harvesting period is the extended flowering and ripening period of goat’s rue beans, the duration of which reaches 25-35 days. The use of the drug Reglon Super based on diquat is a highly effective agrotechnical method that allows increasing the collection of seeds by 24%. The desiccation of the herbage contributes to the production of seeds with high sowing qualities. The seeds with the best sowing qualities are found in beans with yellow, brown, brown or dark brown color of the beans. In light green beans, the seeds are fully formed, but have a high moisture content. Goat’s rue beans do not crack or crumble at the onset of the full ripeness phase. This allows the seed to be harvested when most of the beans are ripe. A comparative assessment of the timing and method of harvesting the seed herbage of the goat’s rue showed that with a ripening of 39% and the presence of 47% of light green and yellow beans, the yield losses ranged from 26 to 56%. The highest seed yield in one confidence interval of 422-453 kg / ha and 444 kg / ha was obtained, respectively, by direct threshing with preliminary desiccation of the grass stand in the ripening phase of 74-97% of beans or by separate harvesting when mowing into swaths during ripening 74 % beans.

AbstractThe aim of this study was to investigate the effects of Cactus (Opuntia spp) levels in total mixed ration silages based on Cactus and Gliricidia (Gliricidia sepium (Jacq.) Steud) on the fermentation profile, microbial populations, aerobic stability and taxonomic diversity. The completely randomized design was used in a 4 × 4 factorial design with four replications, being four rations with different levels of Cactus (15, 30, 45, 60% based on the dry matter) and four opening periods (0, 15, 30 and 60 days of fermentation). An interaction effect (P < 0.050) was observed among the diets and opening times for mould and yeast populations. An interaction effect for the levels of acetic acid was observed, where the diets 15, 30, 45 and 60% showed higher values at 60 days (0.44, 0.41, 0.35 and 0.40 g/kg DM, respectively). A significant difference was observed for the richness and diversity index (Chao1 and Shannon). The most abundant bacterial phyla were Proteobacteria and Firmicutes and the genera Lactobacillus and Weissella. Cactus can be added in total mixed ration silages up to the level of 60% in a way that it positively affects the qualitative indicators of the silages, modulating the taxonomic communities and allowing the predominance of important groups for preservation of the ensiled mass.
