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).

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.

The Difference

The performance of layers on various dietary levels of Leucaena leucocephala seedmeal (LSM) was investigated. One hundred and fifty Dutch Golden Line pullets in their third month of lay, were randomly allotted to five treatments, in which LSM was incorporated at levels of O, 2, 4, 6 and 8%. The study lasted thirteen weeks: ten weeks on experimental and three weeks on basal diets. Egg yolk color, average daily feed intake, percent egg production, egg weight, feed conversion ratio and liveweight gain were performance indices. Egg yolk color was significantly (P < 0.05) enhanced by LSM (at all levels) over control. Layers on 2% and 4% LSM produced significantly (P < 0.05) more eggs than hens on 0, 6 and 8% LSM; the highest production was recorded by hens on 4% LSM. This trend was maintained even after treatment withdrawal. Eggs from pullets on 4% and 6% LSM were significantly (P < 0.05) heavier than eggs from the rest of the treatments. Although the difference between 4% and 6% was not significant the heaviest eggs were collected from birds on 4% LSM. Data collected in this study tend to recommend incorporation of LSM in layers' diets at levels not more than 4%.

Five layer diets were formulated containing 0.5,10, 15 and 20% Anthonotha macrophylla seed meal which replaced equivalent proportion of groundnut cake. One hundred and eighty Babcock brown layers already 3 months in lay were randomized into 5 groups and each group was fed one of the experimental diets for 84 days. The hens were examined for performance using body weight. teed intake, henday egg production, egg weight and feed conversion ratio. The interior quality of Eggs were also assessed. Total feed intake ranged from 9.27 to 10.97kg, average daily feed intake, from 110.32 to 130.54 g/bird/day, hen-day egg production, from 48.88% to 79.11% and feed conversion ratio, from 1.87 to 2.15. Statistical analysis showed that total feed intake,  average daily feed intake and hen - day egg production were similar across the dictary treatments up to the 15% level of inclusion, but were significantly depressed (P<0.05) at the 20% inclusion level.  However, diet had no significant effect on final body weight and average egg weight and feed conversion ration (P>0.05). Similarly results on egg quality showed no significant effect (P>0.05) on albumen index, yolk index, yolk colour, Haugh unit and shell thickness. Based on these results, it was concluded that Anthonotha macrophylla seed meal can be incorporated into layer diets up to 15%, inclusion level without incurring a depression in performance Layer diets containing this meal ingredient had no deleterious effect on egg quality.

KUB chicken is a new breed of local chickens as the result of selection by the Indonesian Research Institute for Animal Production, Ciawi-Bogor. KUB chicken has been developed in South Kalimantan since early December 2013 at farmers assisted by livestock services in South Kalimantan and animal house belongs to the Assesment Institute of Agricultural Technology (AIAT) South Kalimantan. The purpose of this paper is to discuss the potency, production performance, and development opportunities of KUB chicken in South Kalimantan. KUB chickens have several advantages i.e. high egg production (160-180 eggs/hen/year), low brooding (±10%), faster growth, more savory meat taste, and adaptable to environment. Problems encountered in the development of KUB chicken in South Kalimantan are low hatchbility, expensive feed prices, and susceptible to diseases such as Newcastle Disease (ND) and Avian Influenza. Performance of KUB chicken at small farmers in South Kalimantan include egg production 65-67%, egg weight of 36.12-38.12 g/egg, feed consumption 85-105 g/head, feed conversion ratio 3.8-3.9, eggs fertility ranged between 90.21-92.61%, hatchability of eggs is 79.67-81.80% and DOC weight ranged from 34.50-36.86 g/head. Efforts to prevent diseases are the use of herb medicine, ND vaccination, and biosecurity. Appropriate feed technology, disease prevention and strengthen the marketing network are strategies that should be applied to develop KUB chicken in South Kalimantan. This will lead new job and increase farmers’ income.

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.

KUB-2 line of chicken has improved local chicken selected from the KUB-1 chicken line. KUB-2 was selected for more egg production and yellow shank. KUB-1 chicken has 64% various of black feather color, which sometimes tends to have unpreferred dark carcass. Yellow shank color has a positive correlation with the skin color of carcass. As many as 517 pullets of KUB-2 at 4th generation were divided into two groups of 194 pullets of KUB-2kk (yellow shank) and 323 pullets of KUB-2nk non-yellow shank). The chickens were raised intensively in the individual cages for the 24 weeks observation. Variables measured were age at first egg (AFE) bodyweight at first egg (BWFE), egg weight at first egg (EWFE), average egg weight (AEW), average egg production (AEP) during 24 weeks, feed conversion ratio (FCR) of 25-43 weeks of age, and mortality. The result showed that there was no statistically significant different (p>0.05) between KUB-2nk and KUB-2kk respectively for AFE of 156.2 d and 158.1 d, for BWFE of 1788 g and 1808 g, for EWFE of 31.32 g and 31.34 g, for AEP24 of 103.3 eggs or 61.5% and 101.9 eggs or 60.7%, and for FCR25-43 of 3.53 and 3.54. AEW increased with increasing age of hen, the mortality of the whole population was 0.98%.

Abstract. This study was carried out to investigate the effects of fluctuate lighting on performance of laying hens. Two programs were applied with 16 hours daily lighting: step-up (normal) lighting program as the control treatment and a fluctuate lighting program of 2 W/m2 for 45 min and 6 W/m2 for 15 min. Egg weight, feed consumption, feed conversion ratio, henday egg production and hen-housed egg production of the laying hens were recorded for 46 weeks. No significant difference for hen-day and hen-housed egg production between the step up and fluctuate lighting programs (P>0.05) were found. However, fluctuate lighting program resulted in a significant increase in egg weight (P<0.05). Moreover, hens in the fluctuate lighting program consumed significantly less amount of feed and had a better feed conversion ratio than hens in the step-up lighting program (P<0.01). The results of the present study indicate that fluctuate lighting can be used for a profitable egg production.

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.
