Ginger (Zingiber officinale) is one of the important and widely used spices throughout the world in fresh and dried forms. The study on quality characterization and essential oil profiling of 13 ginger genotypes was conducted at ICAR-Indian Institute of Spices Research, Kozhikode, Kerala, during 2019-2020. The genotypes included eight promising exotic accessions (Acc. 393, Acc. 607, Acc. 736, Acc. 833, Acc. 869, Acc. 872, Acc. 873 and Acc. 874), four popular cultivars (Nadan, Himachal, Maran, Rio-de-Janeiro) and a released variety IISR Varada. Significant differences among the genotypes were recorded for various quality parameters such as oleoresin, essential oil and crude fibre content. Among the exotic genotypes, Acc. 869 recorded the highest essential oil content (2.44%), followed by Acc. 393 (2.42%), Acc. 833 and Acc. 873 (2.10%). The accessions, Acc. 869, Acc. 874, Acc. 873 and Acc. 393 recorded higher oleoresin content of 5.88 per cent, 5.63 per cent, 5.34 per cent and 5.28 per cent, respectively. Considering essential oil and oleoresin contents, the exotic accessions, Acc. 873, Acc. 393 and Acc. 869 were identified as promising genotypes. Among the other genotypes, Rio-de-Janeiro recorded the highest essential oil (2.76%) and oleoresin content (6.69%). The exotic genotypes, viz., Acc. 607, Acc. 736 and Acc. 393 recorded crude fibre content of less than 5 per cent whereas, Acc. 869 recorded the maximum of 7.85 per cent. Fifty compounds were identified through essential oil profiling, and the major classes were sesquiterpene hydrocarbons followed by monoterpene hydrocarbons. The major compound identified was α-zingiberene and was highest in Acc. 393 (30.49%), followed by Maran (30.32%).

Grain quality parameters of five new maize inbred lines were investigated and compared with the corresponding properties of two commercial hybrids used in flour production. Kernel of the line L2 had the highest 1000-kernel mass (267.54 g), and line L2 had the highest test mass (844.68 kg m-3 ). The milling response ranged from 9.80 (L2) to 14.03 s (L1). The largest share of the soft fraction of endosperm was determined in L3 (37.13 %), which is slightly lower than in hybrid ZP 633. The highest protein (12.37 %), as well as crude fibre content (2.59 %) was determined in inbred line L4, while the lowest protein was found in the line L2 (9.36 %), and the lowest crude fibre content (1.81 %) was detected in line L3. All tested maize inbred lines were found to be highly prospective for breeding of new hybrids with improved grain quality parameters.

The Friesian cow in Indonesia gives about 1, 500 1. milk in about 240 days compared with 3, 800 1. in 300 days in the Netherlands. The author believes that the main reason for the low production in the tropics is not climate, but faulty feeding practices. A cow fed a typical Indonesian ration of reedy grass and fibrous concentrates gave 1, 003 1. milk in the first no days of her first lactation, but increased to 1, 870 1. in the first 102 days of her second lactation when given a diet containing much less crude fibre, in spite of the fact that the former lactation was in the wet and the latter in the dry season.

This investigation was conducted to determine the effect of organic fertilizers on the content of chlorophyll a, chlorophyll b, antioxidant activity, crude fibre, and zinc in two onion cultivars, Stuttgarter Riesen and Rote Laaer, during 2016, 2017, and 2018. In this research, the following treatments were used: B-Stimul (contains Azospirillum Tarrand et al., Azotobacter Beij., Bacillus Cohn, Chlorella vulgaris Beij., and Herbaspirillum Baldani et al.), EkoBooster 2 (contains biostimulators and mineral salts of nitrogen, phosphorus, and potassium) and Vermifit A (extract of compost of Californian earthworm). The results showed that the application of biofertilizers to onion resulted in the highest chlorophyll b content in 2017 in Stuttgarter Riesen. EkoBooster 2 positively affected crude fibre content in both cultivars, but only in 2016. Antioxidant activity was not significantly affected by the interaction of experimental factors. The application of the biostimulating fertilizers can have a positive impact on the quality parameters of onion, but the kind of fertilizer must be suited to seasonal conditions and the cultivar.

The present study was conducted to develop buckwheat cookies supplemented with wheat flour.Buckwheat and wheat flour were examined for their proximate composition. Buckwheat flour contained11.6% moisture, 15.79% crude protein, 1.81% crude fat, 1.83% ash, 0.70% crude fibre content and 68.27%NFE, while wheat flour contained moisture content 13.12%, crude fibre content 1.93%, crude fat 1.42%,crude protein content 12.53%, ash content 1.57% and 69.43% NFE, respectively. Wheat flour was incor-porated into buckwheat flour at 10, 20, 30, 40 and 50% ratio to make composite flour and the developedcookies were analysed for quality evaluation. Supplementation of wheat flour significantly influenced theproximate and mineral composition of buckwheat flour based cookies. Moisture contents, crude fibrecontents and NFE (Nitrogen Free Extract) increased, whereas crude fat, crude protein and ash contentsdecreased. Mineral contents (Fe, Ca, K, Zn and Mg) of developed buckwheat cookies decreased withincrease in wheat flour supplementation levels. Sensory characteristics of supplemented cookies increasedwith increase in supplementation levels of wheat flour and were acceptable by judges in terms of test,colour, texture and overall acceptability. Cookies developed from C 50% C supplementation level of wheatflour got maximum scored points while C0 control C0 was found to be more nutritious and gluten freehaving more crude protein and mineral contents when compared to supplemented cookies.

The influence of the stage of maturity of alfalfa on the chemical composition and in sacco digestibility was studied in a laboratory experiment. Alfalfa plants were analysed in 8 vegetation stages harvested in regular intervals before the beginning of bud setting until the fall of blossoms. The contents of nitrogenous substances, fat, crude fibre, ADF, NDF, Ca, P, Na, K and Mg were determined in the samples, and using the in sacco method also the organic matter digestibility in the rumen. Further we assessed the energy content and calculated the N−free extractives (BNLV) value. In some stages the chemical changes were monitored in the whole plant. It was discovered that during vegetation there was a statistically significant increase in the crude fibre content and in the ADF and NDF fractions and a reduction in nitrogenous substances. A strong negative correlation was detected between the stage of maturity of alfalfa and content of crude protein and net energy for lactation (r = −0.97 and r = −0.92, respectively). In the individual stages of vegetation the differences in the content of nitrogenous substances, fibre and fat were statistically significant (P < 0.05). The statistically highest content of crude protein (28.97%) was detected in the first stage before bud setting and the lowest (11.97%) in the stage after the fall of blossoms. Later vegetation also had a stronger depressive effect on the content of fat and NEL. The organic matter digestibility (P < 0.05) was the lowest in alfalfa in the last stage of sampling (62.6%) when it reached a mere 85.99% of the digestibility at the beginning of bud setting. The highest organic matter digestibility (72.80%) was detected in a sample of young alfalfa prior to bud setting. In the experiment we confirmed a strong and negative correlation (r = −0.97) between the crude fibre content and organic matter digestibility. The correlation was also strong between the stage of maturity of alfalfa and the content of magnesium (Mg).

AbstractThe aim of the study was to analyse the influence on tail-biting in undocked pigs during the rearing period of crude fibre in piglets' rations. All pigs were fed the same pre-starter until weaning. The study comprised two trials with four experimental groups each. The first trial contained: a control group (CG1) with conventional feed (up to 40 g/kg crude fibre), two groups with an increased crude fibre content of up to 50 g/kg (G5) and 60 g/kg (G6), respectively, and one group with conventional feed and crude fibre provision ad libitum (AL). The second trial consisted of a control group (CG2) which received the same conventional feed as CG1 and three treatment groups with either soya hulls (SS), dried sugar beet pulp (DP) or oat fibre (OF) admixed to their ration, to achieve a crude fibre content of 60 g/kg in all three groups. The rearing week, the batch, the treatment group (only in trial one) and the interaction between batch and treatment group had a significant influence on tail-lesions (P < 0.05). The tail-biting process started in rearing week 3 (trial one) and 5 (trial two), respectively. Due to the low frequency of tail-biting during the present study, crude fibre seems to have no major influence on tail-biting during the rearing period. This unexpected result may be caused by the optimized conditions in which the piglets were kept and the intensive animal observation carried out by the employees. However, the batch effect was most influential.

A field trial was conducted to determine the nutritive value of eight Slovak and Czech red clover varieties and to quantify the effects of variety, cut and year on red clover forage quality. The differences between forage quality of the evaluated red clover varieties were significant for protein supplied when energy is limited in the rumen (PDIE), intestinal digestibility of rumen non-degraded protein (dsi), net energy values and ash content (P &lt; 0.01). The achieved results show that the surpassing forage quality was given by diploid Viglana variety with high protein and energy values. The forage of tetraploid varieties Javorina and Dolina was outstanding in protein content, but had the lowest energy values. The nutritive value was significantly affected by cut. The first cut provided forage with a significantly lower (P &lt; 0.01) crude protein (CP) content, CP digestibility, degradability of CP (degNL), protein supplied when nitrogen is limited in rumen (PDIN), PDIE and with a significantly higher crude fibre content and energy values (P &lt; 0.01). The differences between varieties were more pronounced in the second and in the third cut. Significantly higher (P &lt; 0.01) PDIE, PDIN, degNL, net energy values and ash contents were found in the first production year.

The examination of 108 first year seeds hays showed the average crude protein content to be 9·0 ― and the average crude fibre content 25·7 ―. The crude protein content varied from 5·0 to 13·5 ― and was directly associated with the clover content.Figures obtained on hays cut in the second and third years of the ley suggest that the protein content falls, and the crude fibre content rises, with increasing age of ley.The composition and digestibility of twenty first year hays were determined and the average figures quoted for hays of high, medium and low clover content. The starch equivalent values of these hays were high and moderately constant, varying from 33·3 to 41·2, average 36·8. The protein equivalent values varied from 1·8 to 8·4 ―, average 5·1 ―.The composition and digestibility of four samples of second year seeds hay, two samples of third year hay, one sample of second cut hay in its first year and one sample of lucerne and cocksfoot hay were also determined.
