The objective of this study was to evaluate the effects of dietary supplementation of vitamin E on reproductive performance of Japanese (JP) laying quails from 49 - 132 days of age. A total of 40 JP quails of 49 days of age were randomly assigned to 1 of 4 dietary treatments and there were 10 replicate cages per treatment with each JP quail per replicate. The experimental diets were as follows: (1) the control was a basal diet without vitamin E supplementation (KPCS); (2) E75 consisted of KPCS supplemented with 75 mg vitamin E per kg of feed; (3) E100 consisted of KPCS supplemented with 100 mg vitamin E per kg feed, and (4) E125 consisted of KPCS supplemented with 125 mg vitamin E per kg of feed. The experiment was carried out for 12 weeks from December 23th, 2019 to March 15th, 2020. The results showed that from 105-132 days of age, the laying rate and egg weight of the E100 (93.57% and 11.42 g), control (90% and 11.58 g) and E75 (89.29% and 11.39 g) were significantly higher (P < 0.05) than those of the E125 (79.44% and 10.04 g), respectively. There were no significant differences among treatments in feed consumption and feed conversion ratio (P > 0.05). Egg parameters such as eggshell weight and its percentage, albumin percentage and eggshell thickness were significantly different among treatments (P < 0.05). Briefly, it is suggested that either 75 mg or 100 mg of vitamin E should be added to the feed to improve the egg performance of JP quails.

THE EFFECT OF PARTLY SUBSTITUTION OF DIET WITH WHITE CHINESE CABBAGE (Brasscia pekinensia L) WASTE PRODUCT ON BIOLOGICAL PERFORMANCE OF BROILER CHICKEN The present study was conducted to characterize the effect of white Chinese cabbage (Brasscia pekinensia L) waste product as an alternative feed source for broiler chicken.  The experiment was conducted at Faculty of Animal Husbandry’s experimetal station for 21 days using 60 MB-202 broiler chicken. The experiment was started at 21 days of age and terminated at 42 days of age. Birds were allocated to 20 experimental battery cage, 3 birds in each cage. Completely Randomized Design (CRD) with 5 treatments and 4 replications was employed to analyze experimental data. Treatment diets were formulated as follow: R0 = 100% basal diet and 0% white Chinese cabbage waste product; R1 = 95% basal diet and 5% white Chinese cabbage waste product; R2 = 90% basal diet and 10% white Chinese cabbage waste product; R3 = 85% basal diet and 15% white Chinese cabbage waste product; and R4 = 80% basal diet and 20% white Chinese cabbage waste product. Parameters measured were: 1) daily feed consumption; 2) daily gain; and 3) feed conversion ratio (FCR). The results of the study during which feed consumption (138,09-141,57g), weight gain (64,95-68,53g), and feed conversion (2,07-2,12). The results showed that partly substitution (up to 20%) of basal diet with white Chinese cabbage waste product gave non significant (P > 0.05) effect on feed consumption, daily gain, and feed conversion ratio (FCR) of broiler chicken. It can be concluded that white Chinese cabbage waste product can be used up to 20% feed gives good results on broiler performance. Key Words: Substitution, white Chinese cabbage waste product, broiler performance

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.

UTILIZATION EFFECT OF MOLASSES AS ENERGY SOURCE IN THE DIETS ON GROWING RABBIT PERFORMANCE. Molasses had been used previously in animal feeds. The present study was conducted to determine the effect of molasses utilization in the diets on growing rabbits. The study was conducted during five weeks at Department of Animal and Feed Science Laboratory, Faculty of Animal Husbandry, University of Sam Ratulangi, Manado. Twenty eight-weeks weaned female rabbits with an initial body weight of 600 -700 gr were used in this trial. Animals were allocated in an individual cage. A Completely Randomized Design (CRD) with 4 treatments and 5 replications was used for analysis of variance. Treatments were formulated as follow: R0 = 100% basal diet + 0% molasses; R1 = 98% basal diet + 2% molasses; R2 = 96% basal diet + 4% molasses; and R3 = 94% basal diet + 6% molasses. Variables measured were daily feed consumption, water consumption, daily gain, and feed conversion. Research results showed that average daily feed consumption in the present study ranged from 58.1 to 60.4 g; daily water consumption from 127.2 to 163.8 liters; daily gain from 20.1 to 20.9 g; and feed conversion ratio of about 3.57 to 3.80. Statistical analysis revealed that utilization of molasses replacing part of basal diets up to 6% gave no significant differences on daily feed consumption, water consumption, daily gain, and feed conversion ratio.  It can be concluded that molasses as an energy source can be utilized up to 6% in growing rabbit diets without any negative effects.

The aim of this study was to determine the effect of the genetic groups (three of local quails different with feather color, which are white, black and brown) and the egg weight (three classes of eggs are heavy, medium and light) and the interaction between them on productive performance during the growth phase (0-6 weeks of age). Eggs were individually weighed and graded into three groups: heavy (11.5-12.4g), medium (10.5-11.4g), and light (9.5-10.4g) inside each genetic group. The results of the statistical analysis showed a significant effect (p?0.05) of the genetic group (feather color), egg weight and their interaction on the productive performance during the total breeding period.The brown birds had significantly higher values of body weight, weight gain, carcass characteristics and better feed conversion ratio in all analyzed weeks. The birds which hatched from heavy eggs showed higher value of body weight, weight gain, carcass characteristics, feed consumption and better feed conversion ratio. Brown birds which hatched from heavy eggs had higher value of body weight, weight gain and carcass characteristics, while brown birds which hatched from medium eggs had better feed conversion ratio. We can therefore consider brown quail as the best for fattening purposes

Nghiên cứu nhằm đánh giá ảnh hưởng của mùa vụ đến năng suất sinh sản của chim cút nuôi tại Thừa Thiên Huế. 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).

An experiment was conducted to evaluate the efficacy of AZOMITE® as source of natural minerals on growth performance of commercial broiler. A total of 1,020 day-old Cobb 500 male broiler chicks were randomly allocated to 5 dietary treatments with 6 replications per treatment having 34 chicks in each pen. The five dietary treatments were: (i) basal diet without AZOMITE®, (ii) basal diet with 0.25% AZOMITE®, (iii) basal diet with 0.50% AZOMITE® which was recommended by manufacturer, (iv) basal diet with 0.75% AZOMITE® and (v) basal diet with 1.0% AZOMITE®. Broilers were reared in open-sided gable type house for a period of 32 days. Results showed that the supplementation of AZOMITE® had significant effect on growth performance (p<0.01) of broilers. Live body weight (LBW), body weight gain (BWG), average daily gain (ADG), feed intake (FI), feed conversion ratio (FCR), European efficiency factor (EEF) and gain cost of the birds fed various levels of AZOMITE® were significantly improved as compared to the control. Meat characteristics results indicated that the treatments had no significant effect on dressing percent, thigh, drumsticks and breast percentage among the dietary groups. Taken together, it may be concluded that the supplementation of AZOMITE® in commercial broiler at 0.50 to 1.0% improved live weight, feed intake and feed conversion ratio of commercial broilers.

This study aimed to determine the effect of the addition of fermented moringa leaf powder on feed consumption, egg weight, Feed Conversion Ratio (FCR) of laying ducks. 60 laying ducks were randomized into four treatments i.e. (P0) 0% Moringa leaf powder fermentation, (P1) 0.5% Moringa leaf powder fermentation, (P2) 1% Moringa leaf powder fermentation, and (P3) 1.5% Moringa leaf fermentation. Treatment of concentration refered in 100% commercial feed for 3 weeks. The results showed that the adding of Moringa leaf powder fermentation to feed consumption in each treatment showed significantly different results (p <0.05) in each treatment, with the highest consumption at P2 (176.21 ± 0.92) and the lowest at P0 (158.21 ± 1.07). The results of the study on duck egg weight showed that P1, P2, P3 were significantly different with P0. The highest egg weight in P2 is (70.50 ± 0.34) and the lowest is P0 (66.98a ± 0.29). FCR of laying duck in each treatment showed significantly different results in each treatment, with the highest at P0 (3,81± 0,34) and the lowest at P2 (3,27 ± 0,09). In conclusion, the addition of 1% Moringa leaf powder in 100% of commercial feed can increase feed consumption, increase egg weight and decrease FCR.

Development of poultry has been done in terms of breeding, feeding and management. However, the implementation still faces many challenges such as the problem of production decrease. One cause of the decline in production is a health disorder caused by pathogenic bacteria (Salmonella sp and Escherichia coli). One way to overcome the problem is the use of Piper bettle linn Juice as a feed additive. The purpose of this study is to determine the effect of Piper bettle linn Juice as a feed additive to the performance of laying hens. The method used is the biological test of laying hens age 69 weeks of Isa Brown Strain of 250 laying hens, using Completely Randomized Design (RAL) with 5 treatments and 5 replications. The results of the research showed that Piper bettle linn Juice gave no significant effect (P> 0,05) to feed consumption and mortality. Influence significantly (P<0,01) to Hen Day Production (HDP), egg weight and Feed Conversion Ratio (FCR).

The aim of this study was to determine the effects of in ovo injection of Saccharomyces cerevisiae (SC) to fertile Ross 308 broiler eggs or dietary supplementation on growth performance, internal organ development, gut histomorphology and cecum microbiota during 14 d of growing period. This study was designed as 2×2 factorial experimental design. Fertile 92 Ross 308 eggs were injected with SC solution 0.2ml at 18d of hatch and 90 eggs non-injected as control, afterward dietary SC supplementation was applied during the 14 d to broiler diet. In this study, 160 broiler chicks were used in four treatment groups at 10 replicate for each treatment group and 4 chicks for each replicates. Treatment groups were A) in ovo SC injection + dietary SC supplementation, B) in ovo SC injection + basal diet, C) no injection + dietary SC supplementation, D) no injection + basal diet as control. Live weight, feed consumption, feed conversion ratio and gut histomorphology, caecum microbiota, internal organ weight were recorded at 14 days of age. Live weight gain increased in C group than in the D group. Feed consumption, feed conversion ratio and internal organ weights were not affected by the treatments. Villi length and villi width increased in A group among the other treatment groups in jejunum, villi length increased in A and C groups among the other groups in ileum. Villi length/villi width ratio increased in A group than in the D group in ileum, was not different in jejunum. LAB counts in caecum were higher in A group than those of C and D groups, but was not different from B group. Enterobactericaea count was lower in A and B group than in the D group, was not different from C group. To conclude, results showed that dietary Saccharomyces cerevisiae supplementation increased broiler growth at 14 day by increasing villi development and improving gut health.
