Penggunaan Dandelion (Taraxacum officinale) dalam Pakan Terhadap Performa Kalkun (Meleagris gallopavo)

The aim of this study was to evaluate fresh dandelion leaves on turkey performance. The study used a complete randomized design of 4 treatments and 6 replications. A total number of 24 turkeys (Meleagris gallapavo)-12 week-old were used in this 5 weeks of feed trial. The experimental animals were fed with the diet containing 37% of commercial broiler starter diet, 40% rice bran and forage (water hyacinth and fresh dandelion leaves). The treatments with fresh dandelion leaves addition were P0: 0%, P1: 5%, P2: 10%, and P3: 15%. The variables observed were bio active compound in dandelion leaves, daily behavior and turkey performance. Data were analyzed by Analysis of Variance (ANOVA) and the significant differences between treatments were analyzed by Duncan's Multiple Range Test. The results showed that dandelion leaves contain flavonoids, tannins, saponins and steroids, vitamin D were 17.37 ppm and antioxidants IC50 have an antioxidant activity with a value of 102.31. Observation of daily behavior showed that turkeys behavior was dominated by eating and resting activities, where the highest frequency of resting activities was 0.43 per second (P0). Turkey performance were not significantly different on feed consumption, carcass weight, carcass percentage for all treatments but significantly different (p<0.05) on average daily gain (AVG) and feed conversion ratio. Therefore it can be concluded that fresh dendelion leaves are able to used up to 15% in turkey diet.

ABSTRACT-QMFS2019Poultry production provides source of protein and contributes an important income for Vietnamese farmers. Among the poultry in Vietnam, ducks account for 27.3% of head of poultry and even 55.7% in Mekong Delta region. Along with the development of rearing ducks, bacterial, viral and fungal diseases occurring in the two last decades induced bad effect for poultry producer. Escherichia coli, Salmonella enterica, Streptococcal or Pasteurella act as major pathogenic bacteria in duck. The aims of this study were to investigate the antibacterial activity of garlic Allium sativum against E. coli, Staphylococcus aureus, Salmonella Typhimurium and to evaluate the effect of garlic on growth performance of duck from 1-28 old-days. The results indicated that fresh garlic and dried garlic powder showed inhibitory effect against pathogenic tested strains from 2% and 4% w/v, respectively. The inhibition zones and the minimal inhibitory concentration (MIC) values of garlic extract ranged from 11.3-28.3 mm and 0.02-0.2 g/ml, respectively. After 28 days of diet with garlic supplemented, D3 (2% of fresh garlic in water) showed significantly different in weight gain (WG), feed conversion ratio (FCR), protein efficiency ratio (PER), average daily weight (ADW); whereas, D2 (2% of garlic powder in basal diet) only possessed a difference significant in feed consumption (FC) compared to the D1 (control without garlic supplementation). The obtained results demonstrated the potential of garlic application in poultry production.

UTILIZATION OF “GEDI LEAF (Abelmoschus Manihot (L) Medik) AS“ADDITIVE” IN DRINKING WATER RELATED TO THE PERFORMANCE OF INDONESIAN SUPER NATIVE CHICKEN. Research was done to evaluate the performance of Indonesian super native chicken treated with “Gedi” leaf (Abelmoschus Manihot (L) Medik) as“Additive” in drinking water. Study was conducted using hundred individuals of the Indonesian super native day old chicken. The juice of “Gedi” leaf (Abelmoschus Manihot (L) Medik) was given as in forms of the four treatments as follows, drinking water without “Gedi” leaf as control (P0), drinking water with 10 ml juice of “Gedi” leaf per liter of drinking water (P1), drinking water with 20 ml juice of “Gedi” leaf per liter of drinking water (P2), and drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3). Treatments were applied to the birds at 6 weeks old by completely randomized design five replications at each treatment. Data were taken during 5 weeks. Feeds were using 73 percents of commercial feed added by 10 percents of corn and 17 percents of rice bran with nutritional composition of crude protein 19.49 percents, crude fiber 4.66 percents, fat 3.63 percents, Calcium 1.02 percents, Phosphorus 0.66 percents and metabolic energy of 2920 kcal/kg, all given ad libitum. Variables measurement were focused on feed consumption, drinking water consumption, average daily gain, and feed conversion. Results showed that drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3) was not significantly different with other treatments for feed and drinking water consumption, except for average daily gain and feed conversion. The treatments of P1 and P2 were not significantly different for average daily gain, but these treatments were higher in average daily gain compared with control (P0). The highest value of feed conversion was obtained at treatment P3 and the lowest value was found at treatment P1. These values indicated that the best feed conversion was treatment P1. Therefore, it can be concluded that juice of “Gedi” leaf can be used as the alternative additive feed in drinking water up to 20 ml juice of “Gedi” leaf per liter of drinking water in term of high average daily gain and feed conversion of Indonesian super native chicken. Key words: Drinking water, “Gedi” leaf, Indonesian super native chicken.

Inflammatory bowel disease (namely, colitis) severely impairs human health. Isoleucine is reported to regulate immune function (such as the production of immunoreactive substances). The aim of this study was to investigate whether l-isoleucine administration might alleviate dextran sulfate sodium (DSS)-induced colitis in rats. In the in vitro trial, IEC-18 cells were treated by 4 mmol/L l-isoleucine for 12 h, which relieved the decrease of cell viability that was induced by TNF-α (10 ng/ml) challenge for 24 h (P <0.05). Then, in the in vivo experiment, a total of 44 Wistar rats were allotted into 2 groups that were fed l-isoleucine-supplemented diet and control diet for 35 d. From 15 to 35 d, half of the rats in the 2 groups drank the 4% DSS-adding water. Average daily gain, average daily feed intake and feed conversion of rats were impaired by DSS challenge (P <0.05). Drinking the DSS-supplementing water also increased disease activity index (DAI) and serum urea nitrogen level (P <0.05), shortened colonic length (P <0.05), impaired colonic enterocyte apoptosis, cell cycle, and the ZO-1 mRNA expression (P <0.05), increased the ratio of CD11c-, CD64-, and CD169-positive cells in colon (P <0.05), and induced extensive ulcer, infiltration of inflammatory cells, and collagenous fiber hyperplasia in colon. However, dietary l-isoleucine supplementation attenuated the negative effect of DSS challenge on growth performance (P <0.05), DAI (P <0.05), colonic length and enterocyte apoptosis (P <0.05), and dysfunction of colonic histology, and downregulated the ratio of CD11c-, CD64-, and CD169-positive cells, pro-inflammation cytokines and the mRNA expression of TLR4, MyD88, and NF-κB in the colon of rats (P <0.05). These results suggest that supplementing l-isoleucine in diet improved the DSS-induced growth stunting and colonic damage in rats, which could be associated with the downregulation of inflammation via regulating TLR4/MyD88/NF-κB pathway in colon.

Four trials, involving 124 pigs, were conducted to study the effects of differing planes of nutrition on swine characteristics and to study the relative response of specific genetic groups of pigs to these differing planes. Seasonal and sex effects were also evaluated. Equalized limited feeding to a scale of 75 per cent of the U.S. N.R.C. recommended levels for bacon hogs was compared to liberal feeding wherein pigs were fed to appetite three times daily and to ad libitum feeding.Winter-fed pigs grew slower, were less efficient, had a higher dressing percentage and shorter carcasses than summer-fed pigs.As the plane of nutrition increased, average daily gains increased, feed conversion ratios were correspondingly inferior, dressing percentage rose, backfat thickness increased and area of loin and total Record of Performance score decreased.Females outgained barrows under equalized limited feeding, whereas barrows outgained females at a similar feed requirement by eating more feed under liberal feeding. Female carcasses were superior to those of barrows with a tendency for the differences to be greater under the equalized limited feeding system.Genotype × plane of nutrition interactions were significant for average daily feed consumed (P <.05), average daily gain (P <.01), length (P <.05), and total R.O.P. score (P <.01). Under equalized limited feeding pigs with the ability to gain both rapidly and efficiently tended to produce superior carcasses while under liberal feeding rapid gains seemed to reflect mainly increased feed consumption and a trend toward inferior feed conversion and fatter carcasses.

In this study, it was investigated the effect of clove oil supplementation at increasing levels into laying hens’ diets on performance, egg quality traits, some blood parameters and yolk TBARS (Thiobarbituric Acid Reagent) values. For this purpose 96 Lohman white laying hens, 28 weeks of age, were divided into four treatment groups. Control group was fed with basal diet (C) and treatment groups were fed with diets formed by addition of clove oil at 50 ppm (CO1), 100 ppm (CO2) and 150 ppm (CO3), respectively. During the trial, feed and water were given as ad-libitum, and poultry house was illuminated for 17 hours. Experiment lasted for 13 weeks. Addition clove oil at increasing rates into diet did not affect the live weight. The data analysed as polynomial showed that supplementation of clove oil into layer diet linearly improved feed conversion ratio and increased the egg production. But, daily feed consumption, egg weight, damaged egg ratio and egg quality parameters were not affected by treatments. Serum parameters such as triglyceride, glucose, aspartate aminotransferase, alanine aminotransferase and calcium were not affected by the clove oil supplementation. TBARS values in C, CO1, and CO2 were found higher than the CO3 group fed with diet including 150 ppm clove oil. In conclusion, clove oil at 150 ppm level in diets of laying hens could be used due to extend the egg shelf life and to decline serum cholesterol content.

Abstract This study was conducted to evaluate the effects of corn protein concentrate (CPC) levels in the diets on laying performance, and egg quality of laying hens. A total of 180 64-wk-old laying hens (2.05 kg ± 0.19 kg of live weight) were randomly assigned to 36 cages (5 birds/cage) with separate feeders, including 6 dietary treatments. Birds were fed 1 of 6 experimental diets containing CPC at different levels (0, 0.5, 1.0, 1.5, 2.0 or 2.5%) for 10 weeks. Diets were isocaloric (2850 Mcal/kg) and isonitrogenous (CP, 15.0%), having similar digestible amino acid profile. Hens were weighed at the beginning and at the end of the experiment to determine BW change. Egg production, feed consumption and egg weight were recorded daily, while egg quality variables were evaluated every 14 days. Data were analyzed using the general linear model procedure of SAS in a complete randomized design. The cage was considered the experimental unit. Linear and quadratic effects of treatment were used for mean separation and significance was declared at P ≤ 0.05. Hens fed CPC maintained BW and gain at an increased rate (Quadraic: P < 0.01). Feed intake increased as CPC increased in the diet (Lineal and quadratic: P < 0.01). Egg production, mass and weight were increased as CPC increased in the diet (Quadraic: P < 0.01). Feed conversion rate was improved as CPC increased in the diet (Lineal and Quadraic: P < 0.02). Shell thickness and breaking strength tended to linearly increased as CPC increased in the diet (P < 0.06). Albumen height and Haugh unit were not altered by dietary treatment (P > 0.25). Yolk color was increased as CPC increased in the diet (P < 0.01). Results from this experiment suggest addition of up to 2.5% CPC in the diet enhances egg production and some parameters of egg quality.
