The effect of wheat gluten or extracted soybean meal (300 g of crude protein/head/day) on milk yield, composition and its physical properties was analysed in 53 cows of Polish Holstein-Friesian breed with different milk beta-lactoglobulin (blg) genotypes (AA, AB and BB). The addition of wheat gluten to the diet of cows with the AA and AB blg genotypes caused a significant increase in crude protein (by 0.21; <I>P</I> ≤ 0.05, and 0.19%; <I>P</I> ≤ 0.01), casein (by 0.15; <I>P</I> ≤ 0.05, and 0.15%; <I>P</I> ≤ 0.01) and dry matter content (0.3 and 0.5%; <I>P</I> ≤ 0.05) in milk, and a significant increase in beta-casein production (0.6 g/l; <I>P</I> ≤ 0.05, and 0.6 g/l; <I>P</I> ≤ 0.01) and kappa-casein yield (0.3 g/l; <I>P</I> ≤ 0.05) in the case of cows with the AA genotype. Milk acidity and electrical resistance in milk were lowered. The cows with the BB blg genotype did not show any significant changes in milk composition. The supplementation of extracted soybean meal to cows with the AB and BB blg genotype led to a significant increase in milk protein (0.26% and 0.21%; <I>P</I> ≤ 0.01) and casein content (0.2 and 0.15%; <I>P</I> ≤ 0.01), beta-casein production (0.60 and 0.50 g/l; <I>P</I> ≤ 0.01) and to a decrease in kappa-casein content (by 0.7%; <I>P</I> ≤ 0.05) in cows with the BB genotype. The production of kappa-casein increased in cows with the AB genotype (by 0.2 g/l; <I>P</I> ≤ 0.01). In the case of all genotypes, an increase in milk active acidity and thermostability and a decrease in electrical resistance in milk were noted. It was observed that cows with different blg genotypes differently utilised the protein from given supplements for the production of individual milk components, which may be used in rationalisation of their feeding and improvement of milk content.

Yield And Quality

Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.

A estrutura da pastagem é uma característica determinante tanto da dinâmica de crescimento da planta quanto do comportamento ingestivo dos animais. O objetivo do trabalho foi descrever a densidade da forragem e a proporção dos componentes morfológicos da planta, nos estratos verticais de pastagens de capim Marandu, submetido ao pastejo em diferentes alturas. O delineamento utilizado foi o inteiramente casualizado e as análises de variância e de regressão. Durante o experimento, as alturas médias dos seis piquetes utilizados foram de 10, 17, 18, 29, 32 e 50 cm. O material coletado foi separado, em lâmina foliar, colmo verde e material morto, que foram analisados quanto ao teor de matéria seca, proteína bruta e fibra em detergente neutro. Os estratos verticais apresentaram diferentes composições em relação aos componentes morfológicos de acordo com a altura do pasto. Os estratos próximos ao solo apresentaram maior densidade de forragem com valores de 370 a 543 kg/ha.cm, maior proporção de colmos verdes (30 a 53%) e material morto (25 a 52%) e menor de lâminas foliares (10 a 35%). Independente da altura do pasto, os estratos superiores são mais sensíveis aos efeitos do animal e do ambiente, e apresentaram maiores teores de PB e FDN para lâminas foliares e colmos. Nos estratos acima de 15 cm, os valores de PB e FDN das lâminas foliares verdes variaram entre 10,3 e 13,6% e 49,3 e 54,2%, respectivamente. O manejo em diferentes alturas altera as características dos estratos verticais do pasto, principalmente, nos estratos acima de 15 cm.   Palavras-chave: Altura do Pasto. Densidade Forrageira.

The objective of the work was to describe the density and the proportion of the plant’morphological components, in the pastures vertical strata of Marandu grass, subjected to grazing at different heights. The design used was completely randomized and the analysis of variance and regression.  During the experiment, the average heights of  six paddocks used were 10, 17, 18, 29, 32 and 50 cm. The collected material was separated into leaf blade, green stem and dead material, which were analyzed as to the dry matter content, crude protein and fiber in neutral detergent. The vertical strata presented different compositions in relation to the morphological components according to the height of the pasture.  The near-soil strata showed higher forage density with values from 370 to 543 kg/ha.cm, higher proportion of green stems (30 to 53%) and dead material (25 to 52%) and smaller number of leaf blades (10 to 35%). Regardless of the height of the pasture, the upper strata are more sensitive to the animal and the environment effects, and presented higher levels of CP and NDF for leaf blades and stems.  In the strata above 15 cm, the values of PB and NDF of the green leaf blades varied between 10.3 and 13.6% and 49.3 and 54.2%, respectively. The management of different heights change the characteristics of the pasturevertical strata, mainly in the strata above 15 cm.   Keywords: Height of the Pasture. Forage Density. Green Stems.

The average data for 2018–2019 are presented for yield, dry matter content in grain-haylage mass, nutritional value of test grain-haylage samples produced from plant mass of white lupin, oat and Sudan grass from single and mixed cenosis of different sowing times. The grain-haylage mass was harvested in the phase of brilliantly ripening lupin bean, milky-waxy ripeness of oats and the end of flowering of the Sudan grass. It’s revealed that variants of the second sowing date — 2 decade of May — have the best yield of grain-haylage mass and its dry matter content. The yield of grain-haylage mass in the best variants of the second sowing period exceeded by 7–8 t/ha. According to the nutritional value of grain silage samples (the content of metabolic energy, crude protein, crude ash and carotene), the best results were obtained in most variants of the first sowing period. In content of the metabolic energy and crude protein of 1 kg of dry matter of grain-haylage, the best were variants of the single-species cenosis of lupine and its mixture with oats of the first sowing period. Variants of single-species sowing of lupine and Sudan grass were distinguished by the content of carotene.

Weight Gains

1. A feeding trial is described including four groups of cattle fed on silage only, two mixtures of silage and roots, and roots, straw, hay and oats.2. The live-weight gains made are recorded together with the rate of dry-matter intake.3. The efficiency of the dry matter of the diets was calculated.4. Silage fed alone produced a significantly greater rate of fattening than the other three diets.5. Cattle receiving roots in the morning and silage at night consumed 10·78% more dry matter and made greater live-weight gains than cattle fed on silage in the morning and roots at night.6. Calculation of the starch values of the roots and silage showed that these are higher when fed together than when silage is fed alone or when roots are fed with straw, hay and oats.7. An experiment is described designed to determine the effect of the dry-matter percentage of the diet on dry-matter intake in ruminants and of sudden changes in dry-matter content on digestibility.8. Sheep receiving 19·46% dry-matter silage consumed 16·7% more dry matter and 19·8% more starch equivalent than sheep eating 15·85% dry-matter silage.9. When the dry-matter percentage of the silage fell from 19·46 to 15·77 the digestibility of the dry matter fell by over 10%.10. The starch equivalent of the silage when fed alone was determined from the results of a digestibility trial and according to the performance of the cattle in the feeding trial. The values found were 65·88 and 66·15% respectively.11. The losses suffered in silage-making in twentyfive silos are recorded and discussed. The loss of dry matter and crude protein both average approximately 40% of that ensiled. The need for finding methods of reducing these losses is again stressed.

This study evaluated the nutritional and tannin contents of cooked Kepok banana corm, fermented with Saccharomyces cerevisiae and Aspergillus niger. Corm meal was pretreated by steam for 1 hour at 102 0C before fermenting. The pretreated corms were inoculated with 10% (w/v) inoculum dose with additional nutrient mono-culture or co-culture. A completely randomized design with a 3 x 3 factorial arrangement was used to investigate two main factors: microbial strains and incubation time, with three subfactors each, resulting in nine treatment combinations and three replications. The microbial strain and incubation time significantly (P>0.01) affected the nutrient content of fermented Kepok banana corms. The highest dry matter content (91.84%) was achieved by incubation with S. cerevisiae for 48 h, while 89.61% organic matter was obtained by fermentation with both S. cerevisiae + A. niger for 48 h. The highest crude protein content was 5.81%, which resulted from treatment with S. cerevisiae for 96 h, increasing the crude protein by 61% compared to the control (3.58% crude protein). Fermentation by the microbe consortium (S. cerevisiae + A. niger) for 72 h, produced maximum starch (35.54 g/100 g) and energy (3511 Kcal/kg) values. Thus, the fermented products are a potential source of energy, to be used as feed ingredients.

Gas Tight

Legume–grass forage was ensiled two seasons in 25-ton polyvinyl-encased stacks at dry matter (D.M.) levels of 22 to 37% or stored as field-cured hay. The polyvinyl sleeve coverings provided initial gas-tight conditions. High losses occurred in the high D.M. (32 to 37%) silage during the feeding-out period. Silage quality, as indicated by volatile fatty acid ratios, proximate principles, and digestibility coefficients, was not significantly influenced by D.M. content. When cows were fed the lower D.M. (22 to 29%) silages and hay, forage intake was inversely related to its dry matter content. Intake of high D.M. silage appeared abnormally low. Milk yields appeared to be more consistently influenced by small variations in grain intake than forage dry matter intake through both trials. Milk yields from silages were greater than from hay per unit of D.M. intake. Moisture content of forage had no significant effect on milk composition as indicated by percentage of butterfat, solids-not-fat, or protein.

Results are given from two digestibility trials in which the following three diets were fed to sheep: (i) grass only, (ii) grass+5 oz. cotton cake daily, (iii) grass+10 oz. cotton cake daily.In the first trial the average dry-matter content of the grass was low (approx. 14%), intake was low and the supplements were eaten in addition to the grass. In the second trial where the dry-matter content (approx. 20%) of the grass and the intake were higher, the cake supplements reduced herbage consumption.The feeding of cake did not have any significant effect on the dry-matter percentage in the faeces but depressed the digestibility of the dry matter, crude protein, crude fibre and nitrogen-free extract in the diets including cake and reduced their starch equivalent and total digestible nutrient values.No evidence was found to support the recommendation that undecorti-cated cotton cake should be fed to grazing animals.

Main Factor

Samples of forages were collected throughout the growing season from two dehydrating plants at three different stages of processing: prior to drying, after drying and after pelleting. Samples were analyzed for dry matter, crude protein, fibre, nitrogen content of the acid detergent fibre and pepsin insoluble nitrogen. On the average the amount of heat damage present in the dehydrated samples was quite low (6.11 ADIN % N). There was significantly more heat damage in the samples from the Creston plant. The dry matter content of the material leaving the drier appears to be the main factor related to elevated heat damage.
