Chemical Composition and Nutritive Value of Protein of the Pea Seeds - Effect of Harvesting Year and VarietyWe tested nutritional usability of pea seeds (Pisum sativumL.) at full maturity. Four white-flowering and 5 colour-flowering new Polish cultivars were compared. We determined proximate composition of ground seeds collected over 4 years period as well as amino acids, minerals (Ca, P, Na, K), tannins and fiber fractions (NDF, ADF, ADL). The seeds contained between 224 and 260 g·kg-1of crude protein which was rich in Lys (6.8±0.8 g) but poor in Met+Cys (2.0±0.2 g·16 g-1N). The amount of tannins (as tannic acid equivalent) in white-flowering cvs was 4.3±0.9 g and in colour-flowering - 7.4±2.2 g. The calculated protein nutritional values were compared against amino acid standards of human and animal nutrition and the whole egg protein. Effects of the cropping year and variety variance in respect of chemical composition of seeds were examined. Crude protein, crude oil, N-free extractives, tannins, K, amino acid content: Leu, Phe+Tyr and Ala content were influenced significantly by the cultivar, while the cropping year had a significant influence on dry matter, crude ash, crude protein, crude fibre, crude oil, N-free extractives ADF and ADL fiber fractions, content of P, Na and K, most of the amino acid levels and on nutritional values of the protein measured by means of CS and EAAI indices.

The aim of the study was to determine the variability in the chemical composition and nutritive value parameters of smoked and unsmoked short-ripened rennet cheeses and unsmoked long-ripened rennet cheeses produced by traditional methods. The raw material for the production of short-ripened cheeses was pasteurized cows’ milk obtained from a dairy, whereas the long-ripened cheeses were manufactured from raw cows’ milk obtained from the producer’s farm. All three varieties of cheese examined were produced with commercial dairy starter cultures. The material for the study was collected in winter, directly at the producers’ retail outlets in southern and eastern Poland. The basic chemical composition was determined according to the Polish Standards, whereas the amino acid profiles of proteins from the cheeses were determined by ion-exchange chromatography. The result analysis revealed significant differences between the different varieties of cheese in terms of their water content, ranging from 32.2% to 42.1%, as well as protein content, which varied from 25.6% to 31.6%. Fat levels ranged between 22.2% and 24%, whereas total ash content amounted to 5.1-5.8%. The significantly highest salt content was found in unsmoked short-ripened cheeses. In all three cheese varieties, the total exogenous amino acid content was comparable, ranging from 46.17 g to 47.36 g/100 g protein, and that of endogenous amino acids varied from 52 g to 53 g/100 g protein. The biological value of proteins was determined by calculating to the chemical score (CS), as described by Mitchell and Block, and the essential amino acid index (EAAI), as described by Oser. A comparison of the results with the standard chicken egg white proteins showed that the limiting amino acids for all varieties of cheese were methionine and cysteine. On the other hand, a comparison with the FAO/WHO-suggested pattern of amino acid requirements (1991) for all age groups over 1 year of age showed that the limiting amino acids were methionine and cysteine in smoked and unsmoked short-ripened cheeses, and treonine in long-ripened cheeses. Considering the chemical indices, such as CS and EAAI, it may be concluded that the traditional rennet cheeses produced in southern and eastern Poland have a favourable amino acid composition of proteins and a high nutritive value..

The results of more than fifty estimates1 of herbage yield and ninety-seven analyses of chemical composition are presented in the first of several reports on nutritive evaluation studies of Panicum maximum (guinea grass). Effects of stage of maturity and season are discussed.Herbage yield increased at an increasing rate with maturity, and was depressed by about 40 % in the dry season compared to the wet season. The most significant differences in chemical composition were a decrease in crude protein from 9·8 % to 6·6% and a corresponding increase in crude fibre from 32·1 % to 39·4% as the grass matured from about 2½ weeks to about 2½ months in age. An increased level of nitrogen fertilization resulted in crude protein content being nearly doubled and crude fibre somewhat reduced.

In this paper we analysed the change of the chemical composition and nutritive value of Timothy observed during the spring of 2005. The nutritive value of Timothy was observed between the end of April and the beginning of June relating to the following parameters: crude protein, crude fibre, crude fat, ash, N-free extract, net-energy growth, net-energy lactation, net-energy maintenance, Metabolizable Protein Energy dependent, Metabolizable Protein N-dependent. We also analysed whether a relationship between the environmental factors that affect thegrowing period of grasses and the chemical composition can be detected or not. While testing for correlation, the number of days from 1st January, the amount of heat accumulation, solar radiation and rainfall were considered as independent coefficients.For the estimation of weather conditions we calculated the climate index. The observed year can be described as a year with a rainfall above the average and abundant solar radiation. A correlation can be detected between the change of parameters of nutritive value and the quality of the current year. In 2005 the result of the analysis of nutritive value was showed a significance difference with respect to each chemical composition at the rate of P<0.001 depending on the time when the samples were taken.According to the outlined data it can be stated that the change of the value of crude protein and ash show decreasing tendency agreeing the research literature. In parallel with the change of nutritive value, the amount of crude fibre and N-free extract increased. However, the value of Net-Energy maintenance showed an alteration only in the first half of the observed period. The same alteration tendency can be detected in the Net-Energy growth and the Net-Energy lactation.

The nutrient digestibility and protein utilization of distillery feeds derived from dehulled barley, rye and wheat were studied with growing pigs receiving one of eleven diets in which the protein sources were BDDGS, RDDGS, WDDGS, BDDG, BDS or SBM. In a second trial BDDGS and BDDG were compared with the same feeds treated prior to cooking with cellulase enzyme. The diets, consisting of barley and distillers feed, were fortified with L-lysine and DL-methionine to achieve levels of 13.0 % DCP, 0.80 % lysine and 0.56 % S amino acids. The distillery by-products contained crude protein 24.8—41.5 %, crude fat 6.3—9.5 %, crude fibre 7.1 10.3 %, ADF 18.2—22.9%, NDF 33.3—43.7 % and ADL 8.7—11.3 % on a dry basis. Their lysine content was 0.43—1.36 % of DM and their S amino acid content 0.58—1.36 %. The digestibilities of organic matter and crude protein were 56—83 and 56—79 %. DDGS from rye had low digestibilities and barley distillers solubles high. The cellulase treatment decreased the OM and CP digestibilities by 6.4—10.4 and 15.3—15.4 % units, respectively. FU/kg DM varied from 0.63 to 0.84 and DCP from 177 to 405 g/FU. The N retention of the BDDGS, RDDGS, WDDGS, BDDG, BDS and SBM diets was, respectively, 21.7, 21.1, 24.2, 23.0, 17.7 and 24.6 g/d (P < 0.01) and the biological values were 55, 60, 59, 56, 55 and 66. The daily gains varied from 700 to 762 g. The data indicated that distillery by-products could replace soybean meal quite satisfactorily as a protein source in amino acid-fortified diets.

Palm oil petiole (POP) is a pruning by-product from palm oil plantations. POP is the stalk of the palm oil frond (POF) without the leaflets and the outer layer. By weight, it contributed about 30 percent of POF. POP was a possible alternative for POF in feeding Bali cows (Bos sondaecus) since Bali cows we observed to reject fresh POF. Central Bureau of Indonesian Statistics (2006) reported that the production of POF was around 10,869,365 t from around 3,682,900 ha of palm oil plantation in Indonesia which is equivalent to 3,260,810 t of POP. POF are successfully used as feed for Bos taurus and Bos indicus and there are a lot of studies being done, especially in Malaysia. Alimon and Hair Bejo (1995) reported that the chemical composition of POF is 47, 385, 787, 556 g kg-1 and 5.65 MJ kg-1 for crude protein (CP), crude fibre, neutral detergent fibre (NDF), acid detergent fibre (ADF) and metabolisable energy respectively. However, there is no information on the nutritive value of POP and its palatability in Bali cows. The aims of this study were to evaluate the nutritive value of POP, and palatability of POP types by Bali cows when processed in several forms.

The present investigation was undertaken with the object of ascertaining the effect of cutting at fortnightly instead of weekly intervals on the yield of pastures, and on the composition, digestibility and nutritive value of the herbage.The main trial was carried out on the 1925 light-land pasture. The plot was divided into 14 sub-plots, and one sub-plot was mown per day. The whole plot, therefore, was cut over once per fortnight during the season. The results in respect of yield, composition and nutritive value were compared with corresponding results obtained on the same pasture plot under a system of weekly cuts during 1925.A second trial was carried out on sub-plots 2 and 3 of the 1926 heavy-land pasture, one sub-plot being cut weekly and the other fort-nightly. The work in this case was restricted to securing comparative data in respect of yield and composition of herbage.The results from both trials lead to the conclusion that the differences in chemical composition, both organic and inorganic, between pasture grass cut at weekly and fortnightly intervals are inconsiderable. The dry matter of the fortnightly-cut grass is extremely rich in crude protein and contains, in comparison with grass cut at the hay stage of maturity, a low percentage of crude fibre. Moreover, these characteristics are retained, by systematic cutting at fortnightly intervals, over the entire season.The results of the digestion trials justify the conclusion that the dry matter of the pasture herbage grown under a system of fortnightly cutting is a protein concentrate equal in digestibility and nutritive value to that obtained by weekly cutting. There is no significant running off in respect of composition and feeding value during the second week of growth. At the end of a fortnight the herbage still consists of the same immature, non-lignified. tissue as it was at the end of a week's growth.

SummaryCakes derived from Taramira (Eruca sativa), Raya (Brassica juncea), Toria (B. campestris var. toria) and yellow and brown sarson (B. campestris var. sarson) were evaluated for their contents of crude protein, true protein, essential amino acids, available carbohydrate and tannins. Feeding trials were also conducted to compare the suitability of these cakes with groundnut cake for broilers and White Leghorn chicks up to 4 weeks of age.The crude protein content of Taramira cake was 33% whereas all the other cakes contained 37–38%. True protein accounted for 80–83% of crude protein in all the varieties and albumin and globulin constitutes the bulk of protein. The critical amino acid content of all the brassica seed proteins was found to be higher than that of other vegetable proteins although varietal differences were observed with respect to a few essential amino acids. The hulls accounted for 19% of whole Brassica seed and their removal raised the concentration of protein from 39 to 46% and reduced the crude fibre content from 15 to 6% in the defatted meal. Tannin content was higher in Taramira (1·74%) than in all other varieties (1·0–1·4%) and the major quantity of it was localized in the endosperm. The average metabolizable energy content of all the mustard cakes was 9·62 and 8·75 MJ/kg for meat-type and egg-type chicks, respectively. The nutritive value of Taramira cake was poorer than that of other Brassica cakes or groundnut cake for supporting growth rate of chicks of either breed.

Aims: To determine the chemical composition of serendipity berry (Dioscoreophyllum cumminsii) and miracle fruit (Thaumatococcus daniellii). Study Design: The mean and standard deviation of the data obtained were  analyzed. Place and Duration of Study: Samples were prepared in Department of Food Science and Technology, Osun State Polytechnic, between November 2018 and December 2019. Methodology: Chemical properties of two natural sweeteners namely the miracle fruit (Thaumatococcus danielli) and serendipity berry (Dioscoreophyllum cumminsii) were studied in this work. The fresh fruits were obtained from a farm, sorted, washed and the tissues were scraped, dried in the oven at 45°C for 12 hrs, milled and packed in airtight plastic containers. Proximate, vitamins and amino acid contents of the sweeteners were determined. Results: The results revealed that the protein contents of miracle fruit and serendipity berry were 75.57% and 62.54% respectively. Moisture contents of the sweeteners ranged from 56.95-58.33% while ash contents ranged from 19.33-22.90%. The sweeteners had low carbohydrate and lipid contents. Crude fiber was not detected in miracle fruit but serendipity berry had crude fibre of 5.38%. The fruits had β-carotene contents ranging from 8.44 mg/100 g and 23.00 mg/100 g, vitamin C (20.40 mg/100 g and 22.01 mg/100 g) and vitamin D (17.02 mg/100 g and 19.02 mg/100 g) in miracle fruit and serendipity berry respectively. However, low values were recorded for vitamin E 0.55 mg/100 g and 0.89 mg/100 g in miracle fruit and serendipity berry respectively. The fruits had appreciable amount of essential amino acid which was above 50% of the total amino acid content. Miracle fruit had 51.96% and serendipity berry had 58.07% of the essential amino acid. Aromatic essential amino were 10.78 and 12.79% in miracle fruits and serendipity respectively. Conclusion: This study showed that the two natural sweeteners are good source of essential nutrients and could be used as food supplements in our diet.
