INTISARITujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian tepung daun sirsak terhadap karakteristik lemak darah dan daging itik Tegal jantan. Penelitian ini menggunakan metode eksperimen Rancangan Acak Lengkap. Penelitian terdiri dari 4 perlakuan, yaitu: pakan tanpa disuplementasi tepung daun sirsak, pakan + 5% tepung daun sirsak, pakan + 10% tepung daun sirsak, pakan + 15% tepung daun sirsak. Masing-masing perlakuan diulang sebanyak 5 kali dan setiap ulangan terdiri dari 5 ekor itik. Perlakuan diberikan kepada itik selama 5 minggu yaitu mulai dari umur sebulan sampai umur potong 10 minggu. Data penelitian dianalisis variansi pola searah dan jika terdapat pengaruh perlakuan maka dilanjutkan dengan uji orthogonal polynomial. Hasil penelitian menunjukkan bahwa suplementasi tepung daun sirsak dalam pakan tidak berpengaruh nyata terhadap kadar trigliserida, kolesterol, dan LDL darah serta kadar trigliserida dan kolesterol daging, tetapi berpengaruh sangat nyata (P<0,01) terhadap kadar HDL darah, yaitu menaikkan kadar HDL darah. Kesimpulan penelitian yaitu suplementasi tepung daun sirsak dalam pakan itik tegal jantan sebesar 8,36% menunjukkan kadar HDL darah tertinggi yaitu 99,89 mg/dl, namun demikian suplementasi tepung daun sirsak hingga 15% belum mampu menurunkan kadar trigliserida, kolesterol, dan LDL darah serta kadar trigliserida dan kolesterol daging itik Tegal jantan umur 10 minggu. ABSTRACT

Background and Aim: High temperatures have a detrimental effect on quail performance, even disrupting the immune system and function of the internal organs. This research aimed to investigate the effectiveness of avocado seed powder supplements on meat quality and the liver and kidney functions of culled female quails. Materials and Methods: A total of 100 six-month-old culled female quail were allotted to four dietary treatments, i.e., R0: Basal feed without avocado seed powder supplement and R1, R2, and R3 with basal feed + 3%, 6%, and 9% avocado seed powder supplement, respectively. The observed variables included meat quality (protein, fat, cholesterol and meat collagen, water holding capacity, and tenderness), liver function (liver weight, serum glutamic oxaloacetic transaminase [SGOT], and serum glutamic pyruvate transaminase [SGPT]), and kidney function (urea level, creatinine, uric acid, albumin, and glucose). Results: Analysis of variance showed that avocado seed powder supplements significantly affected the level of SGOT, urea, creatinine, protein, fat, cholesterol, meat tenderness, and cooking loss. A non-significant effect was found on liver weight, SGPT, uric acid, albumin and glucose blood level, collagen, or water holding capacity level. Conclusion: Avocado seed powder supplements improved meat quality as well as the liver and kidney functions of the culled female quail.

The purpose of this research was to know the effect of breadfruit leaves flour in feed to blood profile and correlation between cholesterol, HDL and LDL of blood with meat cholesterol of maleTegal duck of 10 weeks old. The material used was Day Old Duck of male Tegal duck  as much as 120 heads with experimental research methods and Completely Randomized Design (CRD). There were 6 treatments: feed without breadfruit leaf powder, feed + breadfruit flour 3% / kg feed, feed + breadfruit flour 6% / kg feed, feed + breadfruit flour 9% / kg feed, feed + flour breadfruit 12% / kg feed, and feed + breadfruit flour 15% / kg feed. Each treatment was repeated 5 times and each replication consisted of 4 ducks. The variables observed were the number of red blood cells, white blood cells, HDL, LDL, blood triglycerides, correlation between cholesterol, HDL and LDL blood with meat cholesterol of male Tegal duck of 10 weeks old.  The result of the analysis showed that the supplementation of breadfruit leaves has significant effect (P <0,05) on the number of red blood cells, white blood cells, HDL, and blood triglyceride. There is a positive correlation between blood cholesterol with duck meat cholesterol which given breadfruit leaf powder. This research can be concluded that the supplementation of breadfruit leaf powder (Artocarpus altilis) can increase the number of red blood cells, white blood cells, blood HDL level but lowers blood cholesterol and triglyceride blood of male Tegal duck of 10 weeks old. Cholesterol meat is affected by blood cholesterol with regression coefficient of 0.780941, influenced by LDL (r = 0.407849), but negatively affected by HDL (r = -0.47022).

This research was aimed to investigate the different growth and to identify growth hormone gene polymorphism in Muscovy ducks. Two hundred Muscovy day-old ducks consisting of white-plumed male and female duck, black and white-plumed male and female ducks. Body weight was recorded weekly and the obtained data were subject to T test. Primer design used the Custal X Program based on a database from the GeneBank Cairina moschata GH gene, partial cds (AB158762). Primer base sequence of GH gene was forward/Sequence: 5’-CTGGGGTTGTTTAGCTTGGA-3’ and reverse/Sequence: 5’-TAAACCTTCCCTGGCACAAC-3’. The DNA sequences were aligned by using the BioEdit version 7.7 for identification of the single nucleotide polymorphism. The result showed that male Muscovy duck produced higher an average body weight gain and more relative growth than those of females. The highest body weight gain was at three weeks old, and then it started to decrease at four weeks old. The sequencing PCR product obtained nucleotide polymorphism. AA genotype was observed at 136 t of black female Muscovy duck, CC in black and white male Muscovy duck, and white female Muscovy duck. Conclusively, a body weight gain of 3-week-old male Muscovy ducks was higher than that of females and GH gene polymorphism was observed in Muscovy ducks.

The purpose of the research was to assess the effect of α-tocopherol and ascobic acids on the performance and immunity blood profile of male native Muscovy duck. The materials used were 84 male Muscovy ducks at 9 weeks old. The research used completely randomized design with 7 treatments. The treatments were E0C0 : basal diet without α-tocopherol and ascobic acids, E400: basal diet+ α-tocopherol 400IU, E600: basal diet+α-tocopherol 600IU, C400: basal diet+ascorbic acid 400mg/kg, C600: basal diet+ascorbic acid 600mg/kg, E200C200: basal diet+α-tocopherol 200IU+ ascorbic acid 200mg/kg, and E300C300: basal diet+α-tocopherol 300IU+ ascorbic acid 300mg/kg. Each treatment was repeated 4 times and each replication consisted of 3 ducks. The observed variables were body weight, feed consumption, feed conversion ratio, packed cell volume (PCV), total of plasma protein (TPP), leucocyte count, basophil, heterophil, eosinophil, monocyte, lymphocytes count and heterophil/lymphocyte (H/L) ratio of Muscovy duck. The result indicated that E0C0, E400, E600, C400, C600, E200C200 and E300C300 had no significant difference in body weight, feed intake and feed conversion. There were significant effects on PCV, leucocyte count, percentage of heterophil and lymphocytes, but had no significant effect on eosinophil, monocyte and the H/L ratio. The C400 resulted a higher PCV count, percentage of heterophil, and H/L ratio. The C 600 produced the highest leucocyte count. In conclusion, the supplementation of ascorbic acid at 400 - 600 mg/kg feed ascorbic acid could improve theimmune profile, but could not improve the performance of Muscovy duck.

The purpose of the research was to determine the effect of dried soursop leaf meal (annona muricata L.) in rations on weight of intenstine, pancreatis and gizzard of male tegal duck. The research materials were 60 male tegal ducks, dried soursop leaf meal, basal feed consisted of corn 30%, soy bean meal 7%, vegetable oil 6.1%, poultry meat meal 17%, bran 38.2%, L-lysine HCL 0.1 %, DL-methionine 0.3%, Topmix 0.2%, NaCl 0.1% and CaCO31%.The treatments consisted of control diet, basal ration plus 5% soursop leaf meal, basal ration plus10% flour soursop leaves, basal ration plus 15% flour soursop leaves.The results obtaineds the average weights of the intestine, cecum, pancreas and gizzard were 57.1 ± 8.54; 4.15 ± 0.892 g; 3.4 ± 1.188 g; dan 54.1 ± 7.297 g respectively. Analysis of variance showed that the treatments had highly significant effect (P <0.01) on the weights of the intestine with the line equation Y = 3.5550200 + 0.400084X-0.019244X2 and significantly effect (P <0.05) on gizzard with the line equation Y = 4,04208 + 0,070476X but the treatment not significantly effect (P> 0.05) on the weights of the cecum and pancreas. It can be concluded that supplementation of dried soursop leaf meal as much as 10% is the most optimum.
