Abstract

Quail has a high reproductive ability, which can reach 3 to 4 generations a year. The quail also have high eggs productivity and capable of producing 250-300 eggs/quail/year. Egg production is closely related to the reproductive system and feed. It is necessary to know the effect of feeding fermented kangkong on the characteristics and histology of the quail reproductive organs. The increase in livestock population should be balanced with an increase in the availability of feed. Kangkong seeds waste (Ipomoea reptans Poir.) is rejected seeds from seed factories that have the potential to become alternative feed ingredients because it contains about 13.46% protein. The purpose of this study was to determine the effect of fermented kangkong seed feed (Bikafer) on the characteristics of reproductive tract organs and histology of quail oviducts because feeds affect the development of the reproductive tract and quail egg production.  This study used a completely randomized design method (CRD) with 5 treatments and 4 replications. The treatments were as follows: R0 = commercial feed, R1 = 0%  (Bikafer), R2 = 7.5% (Bikafer), R3 = 15% (Bikafer) ,R4 = 22.5% (Bikafer). Data were analyzed using one-way ANOVA with a significance level of 95% (α = 0.05) and the Kruskal-Wallis test, while histological observations were described descriptively. The results showed that there were significant differences in the characteristics of the uterus, vaginal length, and isthmus weights. The histology of the quail reproductive tract developed well and showed the tunica mucosal tissue, serous tunica, muscular tunica, goblet cells, epithelium, and tubular gland cells.

Abstract

Kolesterol tubuh dapat berasal dari dua sumber, yaitu berasal dari makanan (kolesterol eksogen), dan kolesterol yang diproduksi sendiri oleh tubuh (kolesterol endogen).  Jika jumlah kolesterol yang berasal dari makanan sedikit, untuk memenuhi kebutuhan jaringan dan organ lain maka sintesis kolesterol dalam hati dan usus akan meningkat. Sebaliknya, jika jumlah kolesterol dalam makanan meningkat maka sintesis kolesterol dalam hati dan usus akan menurun. Cara yang dapat dipakai untuk menurunkan kadar kolesterol daging dan telur adalah dengan menurunkan kolesterol darah. Penelitian yang bertujuan untuk mengetahui hubungan antara kadar kolesterol darah dengan kadar kolesterol daging dan telur telah dilakukan dengan menggunaan 120 ekor puyuh.  Parameter yang diukur meliputi kadar kolesterol darah, daging, dan telur. Data hasil penelitian dianalisis dengan menggunakan curve expect 1.3. Hasil penelitian diperoleh hubungan antara kadar kolesterol darah dengan kolesterol daging tinggi (r = 0,87) dengan model penduga mengikuti persamaan regresi : Y = -1,0631 + 0,0235X – 0,0001X2, dan hubungan antara kadar kolesterol darah dengan kolesterol telur tinggi (r = 0,89) dengan model penduga mengikuti persamaan regresi : Y = -1,2059 + 0,0190X – 0,0001X2 Kata kunci :  Puyuh, telur, daging, dan kolesterol darah.

Abstract

The main object of this study was to assess the productive and physiological responses of broiler chickens to dietary Pigeon Pea (Cajanus cajan) Leaf Meal (PPLM) as an ingredient. 200 day-old, unsexed Ross (303) broiler chicks were used as experimental birds; they were distributed to (5x10x4) following the completely randomized design (CRD). Experimental diets were formulated to (0.0%, 2.5%, 5.0%, 7.5% and 10.0% PPLM), at the expense of alfalfa meal which was included at 10.0% in the control diet. Feed and water were provided ad labium. Experimental period lasted for 7 weeks. Results revealed that there was a significant difference (P<0.05) in feed intake between level (2.5% - 5.0%), PPLM and control. There was no significant difference in total body weight gain. Feed conversion ratio (FCR) results showed that all birds fed PPLM were lagging after control, no significant difference detected between control and 5.0% PPLM. In conclusion the study showed that Pigeon pea (Cajanus cajan) leaf meal could be included in broiler diets at level 2.5-5.0% without any adverse effects on broiler performance.

Abstract

Starfruit (Averrhoa bilimbi L.) can serve as an acidifier which can improve digestive enzymes work, suppress the growth of pathogenic microbes, protecting feed from microbial and fungal attack and to improve the palatability of feed. The main objective of this study was to determine the effect of starfruit in the ration on the performance (feed intake, body weight gain, feed conversion), the weight of carcass parts, fatty meats, and income over feed cost. The study used 80 chicks two weeks old village with a complete randomized block design experiment method. The treatment consisted of control diet (P0), and three levels of addition of starfruit (P1 = 0.5%; P2 = 1%; and P3 = 1.5%). Each treatment was repeated 5 times. Rations and water were given adlibitum. The trial period lasts for 30 days. Test performed to determine differences in Duncan.The results showed the addition of up to 5% starfruit into the ration does not affect the performance of chicken and chicken carcass weight parts. The highest value of income over feed cost was achieved by treatment with the addition of 0.5% ration starfruit juice.
