Determination of the Optimum Fattening Period and Fattening Performance Slaughter and Carcass Characteristics of Hair Goat and Saanen × Hair Goat (G1) Crossbred Kids Fattened in Different Systems 全文
2021
Hacer Tüfekci | Mustafa Olfaz
This research was carried out to investigate the fattening performance and slaughter and carcass characteristics of Hair goat and Saanen × Hair goat (G1) crossbred kids in different fattening systems. Thirty Hair goats and 30 Saanen × Hair goat (G1) crossbred singleton male kids 2.5-3 months old and weaned were used. The kids were fattened in three different systems: intensive, semi-intensive, and extensive. Marginal value analysis was applied to determine the optimum feeding periods of the kids. In order to determine the slaughter and carcass characteristics, all the kids fattened were taken to slaughter after determining their live weight at the end of the fattening. Live weight gains after the intensive, semi-intensive, and extensive fattening were 17.83 kg, 19.39 kg, and 18.29 kg in the Hair goat kids and 17.88 kg, 18.24 kg, and 17.32 kg in the Saanen × Hair goat (G1) crossbred kids, respectively. In the same order, the average concentrate feed consumed by kids for 1 kg live weight gain was 7.55 kg, 7.28 kg, 7.00 kg and 7.07 kg. Hot carcass weights after the intensive, semi-intensive, and extensive fattening were 13.58, 14.06, and 13.02 kg in the Hair goat kids and 14.21, 15.03, and 14.06 kg in the Saanen × Hair goat (G1) crossbred kids. The Saanen × Hair goat (G1) crossbred goats increased more in live weight than the Hair goat kids and the semi-intensive fattened goats increased more in live weight than the intensive and extensive fed goats. Moreover, the optimum fattening times generally varied between the groups, but not between genotypes within the group.

Organic Agricultural products are natural food products that are checked and certified by authorized institutions at all stages of cultivation and presented to the consumer. In this study, the knowledge and practices of soil agriculture farmers in Amasya province about Organic Agriculture production were investigated by face-to-face survey method. In the survey, the local producers were asked what Organic Agriculture is in general, their status of producing Organic Agriculture, whether they fulfill the Organic Agriculture requirements for Organic Agriculture production. The obtained data were presented numerically and proportionally. Data were also analyzed with the Decision Tree method using the CART (Classification and Regression Tree) algorithm. According to the findings, although the local farmers declared that they knew what Organic Agriculture was at a high level, it was seen that none of the producers fulfilled the requirements of Organic Agriculture in practice. According to the survey data, while the farmers reported that they received the information about Organic Agriculture from TV-radio and the internet to a large extent (58.5%), a very small percentage (11%) stated that they received training. According to this result, it has been concluded that the local farmers do not have enough information about Organic Agriculture, but the lack of information can be easily eliminated via TV-radio and the internet. As a result, it was concluded that Amasya farmers do not have sufficient information about Organic Agriculture production for now, but if appropriate training is provided, successful Organic Agriculture production output can be achieved.

Se condujo un estudio para determinar el efecto de los principios de manejo del Sistema Agroforestal Quesungual (SAQ) en la dinámica de nitrógeno (N) y fósforo (P) del suelo y el impacto de estos en su productividad en el sur-occidente de Honduras, Centroamérica. Se compararon cinco sistemas: (1) tala-y-quema (TQ); (2, 3 & 4) SAQ de <2, 5-7 y <10 años, respectivamente; y (5) bosque secundario. Prácticas locales fueron aplicadas para producir maíz, Zea mays, y frijol, Phaseolus vulgaris, con (101 kg N + 55 kg P /ha en maíz, y 46 kg N + 51 kg P /ha en frijol) y sin fertilización. Las evaluaciones incluyeron descomposición y liberación de nutrientes de la biomasa, mineralización aeróbica de N, fraccionamiento secuencial de P, fraccionamiento por tamaño-densidad de materia orgánica del suelo, y rendimiento. Similitudes en la dinámica del N indican que el SAQ y TQ son igualmente eficientes proveyendo N, aunque en el SAQ como resultado de procesos biológicos. Los reservorios de P fueron más dinámicos y favorables en el SAQ, con menos flujos hacia formas no-disponibles. Basado en la disponibilidad de nutrientes y el rendimiento, el SAQ es una opción factible al sistema TQ en agroecosistemas de pequeña escala.

Five land use systems were compared: (1) Slash-and-burn traditional system; (2, 3 and 4) QSMAS of <2, 5-7 and >10 years old, respectively; and (5) Secondary forest. Local practices were applied to produce maize Zea mays, and bean Phaseolus vulgaris, with (101 kg N + 55 kg P /ha for maize, 46 kg N + 51 kg P /ha for bean) and without addition of fertilizers. Measurements included decomposition and nutrient release from biomass, aerobic mineralization of N, sequential fractionation of P, size-density fractionation of soil organic matter, and crop yield. Similarities in N dynamics indicate that QSMAS and slash-and-burn system were equally effective in providing N, although in QSMAS it is also result of a biologically mediated process. P pools in QSMAS were more dynamic and favorable by reducing their flows towards unavailable forms. Based on nutrient availability and grain yields over time, QSMAS could be a suitable option to replace the slash-and-burn system in smallholder agroecosystems.

Ambient storage stability is one of the major constrains amidst drudges of homemade soymilk due to absence of stabilizer there by restricting the consumption to the production areas. Homemade stabilizers and stabilization becomes the only available option. Soymilk prepared from 12 h steeped and 72 h sprouted soybeans was subdivided and each batch stabilized with 0.5%, 1%, 2% and 3% levels of orange flesh sweet potato starches (OFSPS). Functional properties of the starches and proximate, vitamins, minerals, anti-nutrient, physicochemical, and sensory properties of stabilized soymilk samples were assessed with standard analytical methods. With increase in fortification levels, there were significant improvement in ash (0.84 to 0.88%), protein (4.14 to 4.24%), fibre (0.31 to 0.39%), fat (3.75 to 4.19%), carbohydrate (4.54 to 5.55%), vitamins B1 (0.29 to 0.4 mg/100g), B2 (0.10 to 0.14 mg/100g), B3 (1.03 to 1.13 mg/100g), C (0.86 to 1.09 mg/100g) and pro-vitamin A (5.75 to 6.14 µg/100g). Also improved are calcium (26.81 to 28.55 mg/100g), potassium (31.54 to 32.95 mg/100g), magnesium (44.40 to 46.82 mg/100g), sodium (32.73 to 33.43 mg/100g), iron (2.82 to 3.71 mg/100g), saponin (0.028 to 0.035 mg/100g), tannin (0.041 to 0.048 mg/100g), flavonoid (0.031 to 0.034 mg/100g), alkaloid (0.025 to 0.034 mg/100g), phenol (0.25 to 0.34 mg/100g), viscosity (4.89 to 5.60 mg/100g) and specific gravity (1.02 to 1.04 mg/100g). There were decrease in moisture (86.39 to 84.86%), pH (5.75 to 5.45), visible coagulation time (VCT) (28 to 14 d), foam stability (0.51 to 0.00) and general acceptability (6.84 to 4.84). Functional properties of the OFSPS flour were reasonably high. Despite the anti-nutrient increase, all the soymilk samples in this study were safe for human consumption and moderately accepted at maximum stabilization level of 1%.

Spices and herbs are groups of vegetables with important properties for human health and food industries. They are generally consumed in cooked recipes and such treatment may affect the content of vital components such antioxidants. This study aimed at evaluating the effect of the cooking temperatures on total phenolics, flavonoids and vitamin C of some spices and herbs used in the locality of Bamenda, Cameroon. Briefly, the most consumed spices and herbs were selected through structured questionnaires administered to individuals involved in their consumption and selling. Thereafter, samples were collected and subjected to different boiling treatments and the levels of the antioxidants (flavonoids, phenols and vitamin C) were determined. Results showed that almost half the participants (48%) used Parsley, Basil, White pepper, Njansa, Mint and African nutmeg mainly for flavoring and medicinal purposes. The cooking temperature of 65°C increased total phenolics and flavonoids in spices (Mint, White pepper, Njangsa and African nutmeg) and herbs (Parsley, Basil) while higher heat treatments (75 and 85°C) lowered the content of these pytochemicals. Boiling of spices or herbs significantly and temperature dependently reduced the vitamin C content in all spice and herb samples with respect to the control raw samples. Summarily, the moderate boiling (65°C) treatment used by the local populations favors release of total phenolics and flavonoids though with some reducing effect on vitamin C.

2021
Nesrin İçli | Fevziye Işıl Kesbiç
Tarhana is a traditional food produced by different traditional methods and the materials used in production are changing from a region to another region. The total yeast and molds, total mesophilic aerobic bacteria, Escherichia Coli and enterococci bacteria count of wet dough Kastamonu tarhana and dry powdered tarhana samples were investigated in this study. All microorganisms examined in our study were detected in one of the wet dough tarhana samples. The highest total yeast and molds, total mesophilic aerobic bacteria, Escherichia coli and enterococci bacteria counts were determined for the wet dough tarhana samples to be 2.2×106, 6.6×107, 1.2×106 and 1.9×106 cfu/g, respectively. No growth of microorganism capable of reproduction was observed in the powdered tarhana produced industrially. In addition, the Escherichia coli and enterococci bacteria were not detected for any of the dry powder tarhana samples. It was seen that the microbial load of the wet tarhana produced at home in Kastamonu was higher than the powdered tarhana. The reason for this situation was thought to be due to poor production and hygiene conditions. The presence of Escherichia coli and enterococci bacteria in samples indicates that there is possible fecal contamination of the raw materials used in wet dough tarhana production. Electron microscope images of molds obtained in our study are similar to molds producing mycotoxins. These results show that the wet dough tarhana have a greater risk for microorganism development and human health compared to dry powder tarhana.

Sancar Kansak | Sedat Aktan
Bu çalışmada 32 haftalık yaştaki Japon bıldırcını sürüsünden elde edilen toplam 402 kuluçkalık yumurta, gelişme döneminde kabuk sıcaklığı, kabuk sıcaklığı ile makine sıcaklığı arasındaki fark ve oransal ağırlık (nem) kaybının kuluçka sonuçları üzerine etkilerinin belirlenmesi amacıyla kullanılmıştır. Yumurtalar ağırlık sınıfına göre iki gruba ayrılmış (≤12 g ve >12 g) ve makine katlarına rastgele ve eşit olarak dağıtılmıştır. Beklendiği üzere, kuluçkalık yumurta ağırlığı civciv çıkış ağırlıklarını önemli ölçüde etkilemiştir. Hafif yumurtalar ağır yumurtalara göre daha fazla nem kaybetmişlerdir. Embriyo, gelişme döneminin ilk yarısında hissedilir düzeyde ısı üretememekteyse de (endotermik faz), ikinci yarısında belirgin biçimde ısı üretmeye başladığından (ekzotermik faz), kabuk sıcaklığı makine iç sıcaklığından daha yüksek olmuştur. Bu durum ağır yumurtalarda daha belirgin olmaktadır. Gelişim döneminin ilk yarısında kabuk sıcaklığı hafif yumurtalarda ağır yumurtalara göre daha yüksekken, ikinci yarıda yumurta ağırlık gruplarında belirlenen kabuk sıcaklıkları katlara göre değişmiştir. Genel olarak, büyüyen embriyonun artık belirgin biçimde ısı ürettiği bu geç dönemde iri yumurtalarda ve üst katta yer alan yumurtalarda daha yüksek kabuk sıcaklıkları belirlenmiştir. Alt kattaki hafif yumurtalar, diğer tüm kombinasyonlardaki yumurtalardan daha düşük kabuk sıcaklığı değerlerine sahip olmuşlardır. Son dönem embriyonik ölümler ağır yumurtalarda önemli ölçüde daha yüksek bulunmuştur.

Meric Simsek | Özge Sufer
The objective of this study was to evaluate the physical, bioactive and textural properties of oleaster fruits grown in different locations of Turkey. The oleaster fruits were obtained from Aksaray, Niğde and İzmir cities and their crumb and crust parts were analyzed individually and freshly. In terms of color, the crust and crumb of oleaster fruits from İzmir had the darkest color with L* values of 46.81 ± 4.06 and 78.91 ± 4.97 among all tested fruits from different locations, respectively. Total of phenolic (TP), flavonoid (TF) and tannin (TT) content (C) and as well antioxidant activities (AA) of oleaster fruits were determined for the crust and crumb of oleaster fruits. The highest TPC (22.30±1.75 mg gallic acid equivalent/g DM), TFC (16.24±1.49 mg catechin equivalent/g DM) and AA (14.05±0.55 μmol trolox equivalent/g DM) by DPPH were found in the crust of Aksaray oleaster fruits. In addition, the crumb of Aksaray oleaster fruit had the highest TPC (16.44±1.67 mg gallic acid equivalent/g DM) among the crumbs of oleaster fruits from different locations. Furthermore, there was no significant difference among the texture of crust and crumb of oleaster fruits obtained from different locations. Results showed the growing location of oleaster fruits had a significant influence on the physical and bioactive properties of fruits. Also, this study indicated that oleaster fruits were rich in bioactive compounds; therefore, they could be incorporated into foods to design functional foods.

Aydın Altop | Emrah Güngör | Güray Erener
This study was conducted to investigate the effects of Aspergillus niger strain and inoculum level on the nutritional composition of olive leaves. The experiment had a 2×3 factorial arrangement of treatments with two A. niger strains (ATCC 200345 [A] and ATCC 9142 [B]) and three inoculum levels (104, 106, and 108). Olive leaves were milled to 2 mm and fermented in solid-state by two different A. niger strains and analysed for nutritional composition. Crude protein (CP) was increased linearly as the inoculum level increased. Ether extract (EE) and crude fiber (CF) were decreased linearly in A strain or quadratically in B strain with increased inoculum levels. Crude ash and nitrogen-free extract content did not differ among groups. Strain A increased neutral detergent fiber (NDF) at higher inoculum level, whereas NDF was decreased as inoculum level increased in B strain. The lowest acid detergent fiber (ADF) was obtained from the B strain or 106 inoculum level. The results showed that the effect of two strains on CP and ADF changed similarly with increased inoculum levels. However, two strains affected EE, CF, and NDF content differently with increased inoculum levels. The optimal situations were 108 inoculum level for higher CP, A104 or B104 for higher EE, B106 for lower CF, B106 or B108 for lower NDF, 106 inoculum level or B strain for lower ADF. B strain at 106 inoculation level can be preferred to obtain an average CP and EE content and lower CF, NDF, and ADF content.
