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.

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.

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).

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%.

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.

Feeding Wheat Distillers Dried Grains with Solubles (DDGS) to Laying Hens and its Effect on Performance and Egg QualityThe purpose of this experiment was to determine the effect of wheat DDGS as a feed ingredient on the performance of laying hens and their egg quality. ISA Brown laying hens were administered a feed mixture containing 15% (E1) or 20% (E2) wheat DDGS for 12 weeks. The hens from the control group (C) received a standard diet based on soybean meal as the main protein source only. Laying performance (laying %), average egg weight (g), average daily feed intake (g/hen), and feed conversion ratio (kg/kg eggs) were recorded over the study period. Egg quality traits (egg weight, thick albumen quality, yolk colour, yolk percentage, shell percentage and shell thickness) were evaluated twice: before the start and at the end of the experiment. There was no effect of dietary DDGS on laying performance or on feed intake. The average egg weight was significantly lower in both experimental groups and the feed conversion ratio was lower compared to the control group. Dietary wheat DDGS did not affect the main egg quality parameters except for thick albumen quality. Eggs from hens fed the diet with DDGS had higher values of Haugh unit than those from the control hens. These results suggest that wheat DDGS can be used in amounts of up to 20% as a component of feed mixtures for flocks of laying hens.

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.

SUMMARY The aim of this study was to evaluate the guava extract as an antioxidant additive in diets of Japanese quail breeders on the performance and egg’s quality. The experiment was conducted at University Federal of Goias. A total of 384 Japanese quail breeders were used, distributed in four treatments, with six replicates, with a total of 12 females and four males in each replicate. The treatments were performed with four levels of guava extract in the diets (0.0%, 0.3%, 0.6% and 0.9%). The guava extract contained the ellagic acid, considered the guava antioxidant active principle. The diets were isonutritive. Feed and water were offered ad libitum. The experimental period was 84 days. Egg production, feed intake, feed conversion ratio, egg mass, body weight variation and egg quality were evaluated. The results were submitted to analysis of variance and regression analysis. The adopted probability was 5%. Egg production, feed intake, feed conversion ratio and egg mass were not influenced by the use of guava extract. The yolk and albumen height, the Haugh Unit and the yolk and albumen index decreased linearly as the levels of guava extract in the diet increased. The diameter of the albumen was higher with the use of 0.48% of guava extract in the diet. The yolk color was affected by the guava extract, presenting a darker color with 0.50% of guava extract in the diet. It was concluded that the guava extract used as an antioxidant additive does not improve the performance and egg quality of Japanese 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.

ABSTRAK. Performa produksi, jumlah folikel dan berat organ reproduksi diukur pada 40 ekor ayam petelur yang diberi perlakuan penambahan 5% tepung daun tumbuhan obat yaitu daun Katuk (5%TDK), daun Marigold (5%TDM), daun Senduduk (5%TDS) ke dalam ransum. Variabel yang diamati meliputi konsumsi ransum, persentase produksi telur, egg mass production, konversi ransum, berat dan panjang organ reproduksi dan jumlah folikel. Penambahan tepung tanaman obat tidak mempengaruhi konsumsi ransum ayam petelur. Hasil perhitungan persentase produksi telur mingguan menunjukkan hasil yang sama pada semua perlakuan. Perlakuan 5% tepung tanaman herbal tidak mempengaruhi egg mass production. Konversi ransum pada semua kelompok perlakuan tanaman obat adalah sama. Pemberian tepung tanaman obat di dalam ransum petelur tidak berpengaruh nyata pada jumlah folikel. Berat dan panjang organ reproduksi tidak dipengaruhi oleh perlakuan tepung tanaman obat. Berdasarkan hasil penelitian dapat disimpulkan bahwa penambahan 5% tepung daun Katuk, Marigold dan Senduduk dalam ransum menunjukkan konsumsi ransum, persentase produksi telur, egg mass production, konversi ransum, bobot dan panjang oviduk, berat ovarium dan jumlah folikel yang sama pada ayam petelur.         (Efficacy of medicinal plants on production performance and reproductive characteristics of laying hens) ABSTRACT. Efficacy of Katuk leaf meal, Marigold leaf meal and Senduduk leaf meal on production performance and reproductive characteristics were evaluated. Forty layers aged 32 weeks were distributed into 4 dietary treatments. The layers were housed in individual battery. One-way ANOVA treatment arranged in a Completely Randomized Design was used in this experiment. Dietary treatments were P0 (control without medicinal leaf meal), P1 (diet with 5% Katuk leaf meal), P2 (diet with 5% Marigold leaf meal), P3 (diet with 5% Senduduk leaf meal). This research measured feed intake, egg production, percentage of egg production, feed conversion ratio, number of follicles, weight of ovary, weight and length of oviduct as parameters. Significant results were tested by Duncan Multiple Range Test. The result showed that dietary treatments of medicinal leaf did not affect feed intake and feed conversion ratio of layers. Egg production percentage and egg mass production, the number of follicles, and length and weight of oviduct were similar of all medicinal leaf meal treatments. It can be concluded that feeding medicinal leaf meal did not affect production performance, number of follicles and weight of reproductive organs.
