PENGARUH PENAMBAHAN SARI WORTEL DALAM PENGENCER SITRAT KUNING TELUR TERHADAP KUALITAS SPERMATOZOA KAMBING BLIGON (The effect of carrot juice supplementation in citrate - egg yolk extender on spermatozoa quality of bligon goat)

This study aims to determine the effect of adding various doses of carrot juice into citrate-egg yolk diluents (C-EY) on bligon buck semen quality. Semen was collected twice a week using an artificial vaginal method of three buck with normal body condition and reproductive organs. Semen was 70% of motility, konsentration ≥1000x106mL and abnormality ≤ 15 diluted with C-EY added with carrot juice at a concentrations: 0% (CJ-0), 10% (CJ-10), 12.5% (CJ-12,5), 15% (CJ-15), 17.5% (CJ-17,5), and 20% (CJ-20), and stored in a refrigerator at 3-5o C. The quality of spermatozoa was evaluated every 24 hours. The Variables measured were spermatozoa motility, viability, and abnormalities. The results showed that spermatozoa preserved by C-EY supplemented by 17.5% carrot juice (CJ-17.5) had a higher quality (P<0.05) compared to the other four treatments, with motility (49.04 ± 1.0%), viability (55.70 ± 1.22%), dan abnormalities (4.57 ± 0.88 %) on the 4th day of storage. This study concludes that 17.5% carrot juice into citrate eggyolk extender improves the bligon buck seme

SEPARASI SPERMATOZOA X DAN Y MENGGUNAKAN LEVEL ALBUMIN YANG BERBEDA SEBAGAI MEDIA PEMISAH SPERMATOZOA BABI

  Tujuan dari penelitian ini adalah untuk mempelajari pengaruh penggunaan albumin dengan tingkatyang berbeda untuk memisahkan spermatozoa X dan Y sebagai media untuk memisahkan spermababi jantan. Sperma dipisahkan menggunakan tingkat yang berbeda dari albumin dengan 4perlakuan: rasio antara fraksi atas dan fraksi bawah: 10 dan 30%, 10 dan 40%, 10 dan 50%, 10 dan60% selama 1 jam. Hasil penelitian menunjukkan bahwa proporsi terbaik sperma X oleh fraksi disemua pelakuan, dan juga proporsi terbaik dari sperma Y oleh fraksi bawah pada semua lokasi.Proporsi X:Y dari semen segar (51,68: 48,32 ± 2,66) berbeda (P <0,05) dibandingkan dengan setiapperlakuan sampai fraksi atas (T1 – 74,02: 25,98 ± 5 , 65); T2 – 64,14: 35,86 ± 3,41); T3 – 62,29:37,71 ± 3,98), dan T4 – 59,26: 40,74 ± 4,33)) dan juga fraksi bawah (T1 – 38,13: 61,87 ± 7,69); T2– 35,48: 64,52 ± 6,11); T3 – 30,37: 69,63 ± 4,93); dan T4 – 26,41: 73,59 ± 4,54)). Viabilitas dankelainan sperma setelah dipisahkan tidak berbeda dalam setiap perlakuan. Konsentrasi spermasetelah perpisahan di fraksi atas lebih dari fraksi bawah di semua perlakuan. Sperma babi tidakterpisah selama serangkaian perlakuan dari proses pencucian hingga proses pemisahan dalammedia albumin yang mengakibatkan penurunan motilitas sperma dari 73 ± 3% menjadi 6,5 ± 0,58%pada fraksi atas pada perlakuan pertama sampai 3 ± 0,82% di fraksi bawah pada perlakuan keempatdi akhir pemisahan. Disimpulkan bahwa perlakuan terbaik untuk mendapatkan sperma X olehkonsentrat 10 dan 30% sedangkan sperma Y yang oleh konsentrat 10 dan 60%, sperma setelahperpisahan baik fraksi atas maupun fraksi bawah memiliki motilitas yang sangat rendah

Weather, disease, and wheat breeding effects on Kansas wheat varietal yields, 1985 to 2011.

Wheat (Triticum aestivum L.) yields in Kansas have increased due to wheat breeding and improved agronomic practices, but are subject to climate and disease challenges. The objective of this research is to quantify the impact of weather, disease, and genetic improvement on wheat yields of varieties grown in 11 locations in Kansas from 1985 to 2011. Wheat variety yield data from Kansas performance tests were matched with comprehensive location-specific disease and weather data, including seasonal precipitation, monthly air temperature, air temperature and solar radiation around anthesis, and vapor pressure deficit (VPD). The results show that wheat breeding programs increased yield by 34 kg ha⁻¹ yr⁻¹. From 1985 through 2011, wheat breeding increased average wheat yields by 917 kg ha⁻¹, or 27% of total yield. Weather was found to have a large impact on wheat yields. Simulations demonstrated that a 1°C increase in projected mean temperature was associated with a decrease in wheat yields of 715 kg ha⁻¹, or 21%. Weather, diseases, and genetics all had significant impacts on wheat yields in 11 locations in Kansas during 1985 to 2011

Development and validation of a cultured meat neophobia scale: Industry implications for South Africa

Interest in evaluating cultured meat neophobia is growing as the development of this product continues to progress. As the available evaluation tools have imprecise wording and fall short of providing critical information, this study endeavoured to develop a neophobia scale that captured product-specific nuances of cultured meat. The developed scale was tested using data collected in South Africa. Factor and correlation analyses were conducted to determine the dominant consumer concerns and the groups in society that would face the greatest psychological hinderances to adopting of cultured meat. The study's findings show generally low neophobia in the South African market. Negative sentiment was dominated by meat quality concerns while health, food safety, social and cultural concerns, which normally form stronger objections to food acceptance, were low. The study predicts that market penetration would be hardest among older consumers, due to their relatively higher neophobia. However, if marketing efforts are targeted at addressing consumers’ social concerns, marginal increases in acceptance may be experienced among meat-eaters, people reducing their meat consumption, household heads and consumers from high-income provinces. The study concludes that collaboration between the public and private sectors in the provision of legislation guiding food safety and the setting of quality standards will be key to addressing consumer concerns in the evolving protein supply market

PENGARUH LAMA EKUILIBRASI TERHADAP KUALITAS SEMEN BEKU BABI DUROC DALAM PENGENCER TRIS-MODIFIKASI DENGAN PENAMBAHAN KRIOPROTEKTAN (Effect of equilibration time on frozen sement quality of the duroc pig in tris diluents modification With.....

The purpose of this study was to test the influence of the equilibration time on the frozen semen quality of duroc pig in modified tris-egg yolk with the addition of extracellular cryoprotectants. Semen is collected twice per week using massage methods from two duroc males aged ±2.5 years which in good health and have been trained in semen colection. The design used is a completely randomized design with 4 tests and 3 treatments T1: equilibration time of 1 hour, T2: equilibration time of 2 hours, T3: equilibration time of 3 hours at a temperature of 50C. Observed parameters were motility, viability, abnormality, MPU, and recovery rate (RR). The results showed that motility, viability, abnormalities, MPU, and RR were higher (P<0.05) at 2 hours of equilibration (25.63±3.15%, 55.86±5.41%, 4.92±0.53%, 56.69±5.64%, 36.61±4.49%) compared to 1 and 3 hours (20.00±3.54%, 39.28±9.89%, 7.93±0.76%, 40.21±9.39%, 28.57±5.05%) and (15.00±4.08%, 32.19±7.0%, 8.41±0.70%, 32.71±7.07%, 21.43±5.83%). It was concluded the motility of duroc pig spermatozoa in the tris-modified diluents after 2 hours of equilibration reached 64.375% and 25.63% post thawing, but did not reach the requirement of 40% spermatozoa motility for artificial insemination. It was concluded that the sperm motility of Duroc pig in tris-modified diluent after 2 hours of equilibration reached 64.375% and 25.63% post thawing, but did not reach the standard of 40% spermatozoa motility for artificial insemination
