{"title":"Effect of Wool Handle Grade of Barki Sheep Wool on Its Manufacturing Characteristics","authors":"Aymen Gad-Allah","doi":"10.21608/asejaiqjsae.2023.319312","DOIUrl":"https://doi.org/10.21608/asejaiqjsae.2023.319312","url":null,"abstract":"Egyptian Barki sheep’s wool was subjectively graded and sorted according to handle grade of harshness trait into three categories: soft wool (SW), medium wool (MW) and harsh wool (HW) in addition to the fourth category as a wool left without grading or sorting for comparison; non-sorted wool (NW). Each category was separately mechanically manufactured into woolen yarns of nominal count 6/2 metric. Representative samples of raw wool and yarns after spinning were taken from each category for characteristics measurements. Sorting system significantly affected (P<0.05) staple length and highly significant (P<0.01) affected staple crimps frequency, staple strength, loose wool bulk and resilience, fiber diameter, fine fibers percentage, coarse fibers percentage, hetero-type fibers percentage, kemp fibers percentage, medullated fibers percentage, medullation index and prickle factors. Sorting system had a highly significant (P<0.01) effects on yarn count, yarn twisting, yarn strength, yarn elongation, yarn tenacity, coefficient of variation of yarn mass (CVm%) and thin places. The differences in irregularity of the yarn mass (Um%) were significant (P<0.05). Correlations among wool traits and among yarn characteristics were estimated. The results indicated the importance of separating the soft handle wool part of Barki fleeces which may be used in apparel textiles blends. Such procedure will partially save foreign currency utilized to import fine wool, as well as increased the uniformity of the rest of fleeces and their suitability to carpet manufacture that required harsher wool fibers. Therefore, breeders’ incomes will increase due to the increase in price of wool. This would result in increased the interest of sheep breeding and wool improvement.","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 41","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139141203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary goal of this work was to obtain organic fertilizers for use in agriculture by composting fish waste. Four waste mixtures were used in the experiment: cow waste only (C), cow waste combined with dried fish waste previously collected (CF) with a mixing ratio of 1:3, poultry waste (P), and poultry waste combined with fish waste (PF) at the same mixing ratio. The fish waste treatments (PF2 and CF2) recorded a much lower pH than the untreated treatments with fish waste. The pH values were neutral values after the maturity of fish waste. The highest N percentage was in poultry with fish, followed by cows mixed with fish, poultry, and cows. Over time, the GI increased in all treatments because of the compost maturity, recording values higher than 75%. The results confirmed the compost suitability in all treatments for agricultural use. R 2 values reflect their efficiency in interpreting and predicting the results of GI based on pH, EC, and N. The results showed that the compost physicochemical properties had significant influences on the GI values. The results proved that it is possible to use fish waste mixed with of poultry and cow manure to produce an environmentally safe fertilizer and better than the compost product of poultry and cow manure only","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139140355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research found that the average number of chicks in the semi-closed system was about 9 chicks per square meter, while the average number of chicks in the semi-closed system was about 15 chicks per square meter, which demonstrates the high density in this system. It was also shown that the percentage of dead birds at the end of the cycle in the semi-closed system amounted to about 6% of the total chicks, while the percentage of dead ones at the end of the cycle in the average semi-closed system was about 4% of the total chicks, which shows the low percentage of dead ones in the average semi-closed system, and it became clear that the average amount of feed consumed In the semi-closed system, it was about 4.8 kg per chick, while the average amount of feed consumed in the average semi-closed system was about 4.1 kg per chick. The feed conversion efficiency in the semi-closed system was about 60%, while the feed conversion efficiency in the system was about 4.1 kg per chick. the semi-closed system rate is about 74%, which shows the high rate of food conversion, which provides large amounts of feed, which is a major problem these days in terms of their availability and prices. It was also shown that the total costs in the semi-closed system amounted to about 55 pounds per chick, while the costs amounted to the average total revenue in the semi-closed system was about 47.5 pounds per chick. The total revenues in the semi-closed system amounted to about 60 pounds per chick, while the total revenues in the average semi-closed system amounted to about 69.2 pounds per chick. Studying the difference between the two systems using formal variables shows an increase and superiority of the semi-closed system modified due to the closed system in the density of birds, the percentage of vitality, the average weight of the bird, the rate of production efficiency, and total revenues in pounds, and a decrease in it in each of the total variable costs in pounds, the total costs in pounds, and the amount of feed User for each bird. It was also shown from the total output function of the modified semi-closed system that the most important production elements that have a significant impact on the total output of one cycle of chicken farms in broiler houses is the amount of feed provided throughout the production cycle, whereas in the semi-closed system it was the amount of feed provided throughout the production cycle and bird density. The cost elasticity for the modified semi-closed system was 0.87, while for the semi-closed system it was 0.99.","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139141844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
