The effect of ADD-H at 3 or 4 rates of application on the quality and feeding value of baled hay at 3 dey matter levels (65.0—69.9, 70.0—74.9 and 75.0—79.9 %) was studied on Hankkija’s farm in Kangasala and at DM 78—82 % on the Koivisto farm in Hausjärvi. The field experiments were performed in 1979 and the testing of the hay completed by the following spring. The field experiments were affected by uneven drying of the hay, uneven rewetting due to rainfall after cutting, loss of ADD-H during application, uneven distribution of ADD-H in the bales, and other factors. At DM 65.0—69.9 % ADD-H gave only a slight improvement in hay quality; at the highest application rate the sugar content was the highest and the crude fibre content the lowest. At the other DM levels ADD-H restricted the generation of heat during storage; the sugar content was higher, and the mould count lower, in the treated hay than in the untreated hay. The beneficial effect of ADD-H on the feeding value of baled hay was small; further study on this aspect is required.

The apparent digestibility of crude protein by the non-ruminants, pigs, horses, rats, man and the rabbit, is shown to be related to the crude protein content of the feed, and the form of the relationship is similar to that for ruminants. With non-ruminants the apparent digestibility of crude protein is markedly depressed by the crude fibre content of the feed, whereas with ruminants the depression is only slight. The relevant equations show that pigs are much more sensitive to crude fibre than horses and rabbits, and both the latter react more markedly to crude fibre than do the ruminants.Despite the apparently significant differences between the equations for the ruminant and nonruminant herbivores, it is shown that over the normal range of crude protein and crude fibre content in feedingstuffs suitable for herbivores, the apparent digestibility coefficient of crude protein is similar for all. In other words, despite different abilities to cope with crude fibre, the herbivores as a class digest crude protein in normal feeds to much the same extent. On the other hand, the pig, an omnivore, is shown to be very markedly affected by the crude fibre content of such feeds.

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.

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).

Aim: This work gives the reports on experimental study of the effects of drying on some selected vegetables, namely fluted pumpkin (specimen I), spinach (specimen II), lettuce (specimen III), and waterleaf (specimen IV). Methodology: The vegetable specimens were dried at regulated drying temperatures of 323K, 333K, and 343K, and the percentage amount of water, fat, crude fibre, ash, protein, and carbohydrate, as well as the fungi and bacteria counts in the vegetable specimens was determined at these temperatures. Results: The results revealed that the amount of water in the vegetable specimens reached 0% earlier at the regulated drying temperature of 343K than at the other regulated drying temperatures. The results also indicated that the dried vegetable specimen II has highest fat content of 8.2%, the dried vegetable specimen III has highest crude fibre content of 14.5%, the dried vegetable specimen IV has highest ash content of 18.6%, the dried vegetable specimen I has highest protein content of 30.3%, and the dried vegetable s specimen III has highest carbohydrate content of 42.2% at the regulated drying temperature of 323K. The same trend of results was obtained for the regulated drying temperatures of 333K and 343K. Furthermore, the results showed that at the regulated drying temperature of 323K, the dried vegetable specimen III has the lowest bacteria counts of 4.3 x 107 CFU/g. The trend of result obtained for the regulated drying temperatures of 333K and 343K is similar to that of the 323K. At the regulated drying temperature of 323K, the dried vegetable specimen II has the lowest bacteria counts of 1.7 x 107 CFU/g. The same trend of results was obtained for the regulated drying temperatures of 333K and 343K. Conclusions: Drying has effects on the percentage amount of fat, crude fibre, ash, protein, and carbohydrate in the vegetable specimens. The microbial counts and the fungi counts decrease when the temperature increases. The present work can be applied in food engineering industries, and engineering in agriculture.

This study investigated the effects of culinary methods (boiling and frying) on the proximate composition of an edible insect commonly known as African Palm Weevil (R. phoenicis) Larva(e). The proximate composition (moisture, ash, protein, crude fibre, fat and carbohydrate contents) were determined using standard methodology of the Association of Analytical Chemists (AOAC). Boiling increased the moisture and ash content but, decreased the protein, fat, carbohydrate (p0.05) and the fibre content compared to the raw sample. On the other hand, frying increased the protein and ash contents (p 0.05) but decreased the moisture, fat, carbohydrate and fibre contents compared to the raw. The decrease in moisture content led to a corresponding increase in the protein, and ash contents of the fried sample, which indicates high protein and mineral levels of the larvae. Also, the lowest moisture content recorded in the fried sample compared to the raw and boiled sample was an indication of reduction of microbial spoilage, and longer storage shelf life of this edible larva. Therefore, frying is recommended as the best culinary method for healthy diet.

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.

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.
