Duck is one of the commodities that contribute to the national livestock production and Central Java is home to the fourth biggest duck population after West Java, South Sulawesi and East Java. The 2019 egg production in Central Java was 36.174 tons or 11.3% of the total egg production nationwide. Accordingly, it is important to investigate the effect of environmental factor, total number and age of ducks on egg production in Central Java. Specifically, this study aimed to observe the effect of region on egg production and feed conversion ratio (FCR) and the total livestock (chicken), age (month), stocking density (ducks/m2), internal housing temperature (oC), and humidity (%) on Hen day production/HDP. A survey engaging purposive random sampling was conducted on the population of duck farming in Central Java especially Tegal, Pemalang and Brebes districts. The data were subjected to General Linear Model (GLM) and a regression-correlation analysis using an SPSS program. The result showed that region significantly  affected hen day production (HDP) but did not affect FCR. Housing temperature affected HDP by 14.9% and the higher the temperature, the lower the HDP. Duck age affected HDP by 11.7%, and the older the ducks the lower the egg production. Duck population, stocking density and humidity did not significantly affect egg production. Conclusively, duck egg production (HDP) is significantly affected by temperature inside the housing and the duck age.

Shrimp Cultivation

The failure of tiger shrimp (Penaeus monodon) farming could make farmers stop their cultivation activities. As an alternative, vannamei shrimp cultivation gives hope for productive, profitable, and sustainable cultivation. The development of shrimp farming in Tegal City is carried out through simple methods, intensive technology, and the use of Busmetik technology or mini-scale shrimp farming on plastic ponds. The high demand in the shrimp market continues to encourage farmers to increase their productivity by increasing stocking density. The purpose of this study is to determine the performance of vannamei shrimp cultivation which is cultivated intensively including yields, survival rate (SR), feed conversion ratio (FCR), and shrimp growth in Tegal City, Central Java Province. The research was conducted from July to October 2019. The research method used was a case study with 16 plots of ponds, and the average area of the pond was 1000 m². Based on the results of the calculation, it can be seen that the average yield is 1,603 kg per pond with a stocking density of 100 fish/m², a survival rate (SR) is 85.6%, a feed conversion ratio (FCR) is 1.41 and the shrimp growth is 0.16 grams per day. Economically, based on the Benefit-Cost Ratio (B/C ratio) of 1.46, vannamei shrimp cultivation in Tegal City is profitable so that shrimp farming can be carried out sustainably.

Zinc Levels

Vitamin E and zinc are necessary for preventing free radical damage to phospholipid membranes, enzymes and other important molecules. The objective of this study was to evaluate the effect of dietary vitamin E and zinc levels on performance and lipid oxidation in fresh and stored eggs of laying duck. A total of 90 of 22 weeks old ducks were randomly divided into 15 experimental units by assigning a completely randomized design with 5 treatments and 3 replications. The treatment diets were R1 (control diet), R2 (R1+40 IU vitamin E), R3 (R1+80 IU vitamin E), R4 (R1+100 ppm organic zinc), and R5 (R1+200 ppm organic zinc).The experiment was carried out for 8 wk. Parameters observed were feed intake, egg production, egg weight, feed conversion ratio, and Thiobarbituric Acid Reactive Substances (TBARS) value. The results showed that increasing of vitamin E from 40 IU to 80 IU and zinc from 100 ppm to 200 ppm did not affect feed intake and egg weight. Otherwise, the dietary Vitamin E and organic zinc significantly decreased (P<0.05) feed conversion ratio and significantly increased (P<0.05) egg production and decreased (P<0.01) TBARS values. It is concluded that dietary 40 IU vitamin E or 100 ppm organic zinc could increase the performance of laying ducks and dietary 200 ppm organic zinc was more efective to be antioxidant than 40 and 80 IU vitamin E.

Treatment Groups

One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24 mg/kg feed), and a basal diet including an ANT (avilamycin, 10 mg/kg feed). Each treatment comprised 4 replications with 4 cages (15 quail per cage), amounting to 60 quail per treatment group. Diets (in mash form) and water were provided forad libitumconsumption. EOM consisted of 6 different essential oils derived from the following herbs: oregano (Origanumsp.), laurel leaf (Laurus nobilisL.), sage leaf (Salvia trilobaL.), myrtle leaf (Myrtus communis), fennel seeds (Foeniculum vulgare), and citrus peel (Citrussp.). In comparison with the control diet, adding supplements such as EOM and ANTs to the basal diet increased egg production in quail (P<0.001). However, egg production was similar between EOM and ANT treatment groups. Moreover, there were no differences between the treatment groups with regard to egg weight. Feed intake was not affected by EOM or ANT supplementation, whereas feed conversion ratio was significantly improved by EOM and ANT supplementation. Thus, we concluded that EOM has beneficial effects as a dietary supplement on egg production and feed conversion ratio.

Context Heat stress poses a major limit to poultry production. Moringa stenopetala leaf meal (MSL) could be a promising feed additive for poultry raised under heat stress, as it is rich in antioxidants. Aims To determine the effect of (MSL) supplementation on the production and quality of broilers under heat-stress conditions. Methods In the broiler performance trial, 156 1-day old Cobb 500 broilers were assigned to four groups, with each containing three replicates of 13 chicks. For the egg production trial, 108 Bovan Brown layers aged 20 weeks were allocated to four groups, with each containing three replicates of nine hens. The four groups of broiler and layer chicken were supplemented with MSL at a level of 0% (control), 1% (MSL1), 1.5% (MSL1.5) and 2% (MSL2). Relative humidity, and minimum and maximum temperatures were 82%, 13°C and 23°C respectively. The effects of MSL supplementation on growth performance, characteristics of digestive organs, carcass traits, egg production and egg quality were analysed with one-way ANOVA. Key results Moringa stenopetala-leaf supplementation at a level up to 2% (MSL2) did not significantly affect feed intake, weight gain or feed conversion ratio of the birds. Supplemented broilers had a significantly longer large intestine (24% for MSL1, 37% for MSL1.5 and 49% for MSL2) and a heavier pancreas (82% for MSL1, 67% for MSL1.5, and 57% for MSL2) than did the control broilers. Hot and cold carcass weights, dressing yield, dressing percentage, breast-meat weight, drumstick and thigh-meat weights, wing-meat weight, back weight and meat pH were not significantly affected by MSL supplementation. Ash content of meat of the MSL2-fed birds was significantly higher than that of the control birds (3.51% vs 2.74% respectively). Egg production, feed conversion ratio and interior and exterior egg-quality parameters were not significantly affected by MSL supplementation. Intensity of yolk colour was significantly and linearly enhanced due to MSL supplementation (by ~5–8 times compared with the control). Conclusions Supplementation with MSL at a level up to 2% improved yolk colour of Bovan Brown layer eggs, with no effect on meat and egg production. Implications Yolk colour of eggs of layers raised under heat stress can be improved by MSL supplementation at 1%, with there being a minimum increase in the diet cost.

The development of free-range chicken farm is constrained by expensive food prices. On the other hand,feses of cattle had potential use as a source of feed. This study was conducted to determine the response ofcow feses and probiotics administration in the diet of laying range chicken. The study was conducted over 6months using 240 free-range chickens aged 8 months. Research was arranged in a completely randomized designwith 8 treatments and 5 replications. The treatment given were ration in accordance with the farmers formulacomprising: concentrate: 25%, corn 40% and rice bran 35% (P0) and ration as P0, with the substitution of ricebran with fermented cow feses each treatment with level 10 % (P1), 15% (P2) and 20% (P3) and ration as atP0, P1, P2 and P3 that received additional probiotic (Bio L) 1 cc / L of drinking water (P4, P5, P6 and P7). Theparameters were observed are: egg production (hen day), egg weight, feed intake, FCR (Feed Conversion Ratio)mortality and physical composition of eggs. The results showed that the diet which containing fermented cowfeses 20% did not decreased egg production and feed efficiency. The combination of fermented cow feses at thelevel of 20% with a probiotic (Bio L) 1 cc / L of drinking water showed that egg production  increased althoughit is not significant and reduce the number of FCR (Feed Conversion Ratio). In conclusion the use of fermentedcow feses up to the level of 20% in the diet both with and without the administration of probiotics, has no effecton physical composition of eggs.

Thí nghiệm đã được tiến hành trên 108 chim cút đẻ trứng thương phẩm trong 6 tháng đẻ trứng vào 2 mùa vụ bắt đầu đẻ trứng: vụ Đông - Xuân (từ 12/2018 đến 5/2019) và vụ Hè - Thu (từ 6/2019 đến 11/2019). Chim cút được cho ăn thức ăn hỗn hợp hoàn chỉnh cho cút đẻ của công ty cổ phần Greenfeed Việt Nam. Kết quả nghiên cứu cho thấy đàn chim cút đẻ vào vụ Đông - Xuân có năng suất trứng và tỷ lệ đẻ lần lượt là 20,76 quả/mái/tháng và 69,21%; cao hơn so với đàn chim cút đẻ vào vụ Hè - Thu với kết quả tương ứng là 18,25 quả/mái/tháng và 60,84% (P<0,05). Hệ số chuyển hóa thức ăn (FCR)  trung bình cả giai đoạn của đàn chim cút được nuôi trong vụ Đông - Xuân thấp hơn so với vụ Hè – Thu (3,22 so với 3,75 kg thức ăn/kg trứng) (P<0,05). Khối lượng trứng trung bình của đàn chim cút dao động từ 10,49 đến 10,74 g/quả. Tỷ lệ lòng trắng trứng của trứng cút đẻ trong vụ Đông - Xuân thấp hơn so với đàn chim cút đẻ trong vụ Hè - Thu trong khi tỷ lệ lòng đỏ lại có xu hướng ngược lại (P<0,05). ABSTRACT This study was carried out to determine the effect of seasons on reproductive performance of egg-quails in Thua Thien Hue province. A total number of 108 6-months female quails laying in 2 different group seasons when quail starting laying was chosen to collect the data: Winter - Spring season (from December 2018 to May 2019) and Summer - Autumn season (from June 2019 to November 2019). The quails were fed by the complete feed of GreenFeed Vietnam Corporation. The results showed that quails laying in Winter - Spring season had higher egg production, laying rate and average feed conversion ratio than quails laying in Summer - Autumn season (P<0.05). Egg production, laying rate and average feed conversion ratio of quails laying in Winter - Spring and Summer - Autumn season were 20.76 and 18.25 egg/quail/month; 69.21 and 60.84% and 3.22 and 3.75 kg feed/kg egg, respectively. An average of egg weight was 10.49 - 10.74 g (P>0.05). The percentage of albumin of the quails laying in Winter - Spring season was lower than that of the quails laying in Summer - Autumn season while the percentage of yolk tended to be opposite (P <0.05).
