The Combination of Attapulgite, Betaine, and Chromium with Curcumin on Lipid Metabolism in Laying Hens under Tropical Conditions

Liver health in laying hen is associated with lipid synthesis and metabolism. This study focused on oxidative parameters to maintain liver health and lipid metabolism in laying hens. The efficacy of curcumin as a herbal compound, combined with attapulgite, betaine, and organic chromium in a feed additive called Citrus XL, was evaluated in terms of its impact on lipid metabolism. This study involved 2000 ISA Brown strain laying hens aged 82-87 weeks. The heat stress index was calculated based on a temperature of 26.71 ± 1.11 oC and humidity of 83.21 ± 6.86 % in open-house cages with an 18-hour lighting period. This experiment included four treatments with five replications, including a basal diet with no Citrus XL (Control), a basal diet plus 0.5 kg/ton of Citrus XL, a basal diet plus 1.0 kg/ton of Citrus XL, and a basal diet plus 1.5 kg/ton of Citrus XL. To do so, blood biochemistry, fat content, liver score, malondialdehyde (MDA), and superoxide dismutase (SOD) levels were measured. The results indicated a significant increase in HDL levels as well as a reduction in LDL and MDA levels, liver scores, and egg yolk fat content. In conclusion, the treatment with 1.0 kg/ton of Citrus XL yielded the best results in terms of HDL, liver score, and liver MDA while Citrus XL treatment with 0.5 kg/ton produced the best results for LDL and yolk fat content.

Egg Quality of Layer Hens Reared in Two Different Housing Systems

This study aims to determine whether there is a significant difference in the quality of eggs from chickens raised in closed-house and open-house cages. This study was conducted in Close housed and house cages for Isa Brown strain layer chickens in the Blitar Regency area in May 2024. The materials used in this study were 40 eggs of 68-week-old Isa Brown strain chickens kept in closed houses and open houses. This research was conducted using an experimental quantitative method using an unpaired t-test, which was analyzed using the Microsoft Excel application. The results showed that the egg weights of chickens reared in the closed house and open house were 63.80 g and 59.68 g; the egg index was 79.06 from the closed house cage and 76.19 from the open house cage. The Yolk index was 0.65 from the closed-house cage and 0.74 from the open-house cage. Haugh Unit (HU) 61.90 from the closed house cage and 64.40 from the open house cage. This study concludes that there is a significant difference in the quality of eggs from chickens reared in closed and open houses. The best egg weight and index were found in chickens reared in a closed house. At the same time, the best yolk index and HU were found in eggs from hens reared in open houses.

GROWTH PERFORMANCE OF ISA BROWN COCKERELS FED GRADED LEVELS OF AIR-DRIED NEEM LEAF AND BARK MEAL

Poultry farmers prefer rearing of healthy birds using natural growth and health promoting additives. Azadirachta indica (neem leaf and bark) has good potential as feed additives. This study assessed the effect of graded levels of neem leaf and bark meal on performance and carcass characteristics of ISA Brown cockerels. Two hundred and seventy (270) day-old ISA Brown strain cockerels were used for the study. The birds were randomly allotted to nine dietary treatments of thirty birds each, replicated thrice with ten birds per replicate. The treatments were 0g Neem Leaf Meal (NLM) and Neem Bark Meal (NBM) as control, 2.5g, 5.0g, 7.5g and 10.0g NLM/kg feed, 2.5g, 5.0g, 7.5g and 10.0g NBM/kg feed in a Completely Randomized Design. Birds were fed the experimental diets from 1st week to 20th week of age. Daily feed intake (DFI), Daily Weight Gain (WG) and Feed Conversion Ratio (FCR) were evaluated. Data were analyzed using General Linear Model. Cockerel chickens fed 2.5g/kg NLM exhibited significantly highest Final Weight (FW), DWG, and ADG during the starter phase compared to the control. In the grower phase, birds fed 5.0g/kg Neem Bark Meal (NBM) showed significantly heaviest FW, DWG, and ADG. In conclusion, feeding ISA Brown cockerels with neem bark meal up to 5.0g/ kg of feed enhance performance at finisher phase.

Effect of the Addition Red Beetroot Powder (Beta vulgaris L. Var. Rubra L) as a Feed Additive in Feed on Production Performance, Egg Yolk Cholesterol and Blood Profile of Laying Hens

The aim of this research was to evaluate the effect of addition red beetroot powder (Beta vulgaris L. Var. Rubra L) as a feed additive in feed on production performance, egg yolk cholesterol and blood profile of laying hens. The first stage of research included testing the inhibitory power of Escherichia coli, Salmonella sp, and Lactic Acid Bacteria (LAB). The materials used in the bacterial inhibition test were red beetroot pulp powder, red beetroot peel powder and red beetroot pulp and peel powder. The method used was in vitro research and the data was analyzed statistically using the ANOVA test. If there were differences between each treatment, it was continued with Duncan’s Multiple Range Test. The second stage of research is the field application of the results of the first stage research in vivo. The material used was 120 laying hens of the isa brown strain aged 30 weeks. The method used was an experimental method using a Completely Randomized Design (CRD) with 4 treatments and 6 replications, each using 5 chickens. Data were analyzed statistically using the ANOVA test. If there were differences between each treatment, it was continued with Duncan’s Multiple Range Test. Variables observed in the second stage of research included production performance, egg yolk cholesterol and blood profile of laying hens. The results of the first stage of research showed that the use of red beetroot plant powder had a very significant effect (T<0.01) on the diameter of the inhibition zone for Escherichia coli, Salmonella sp and Lactic Acid Bacteria (LAB). Red Beetroot Pulp and Peel Powder (RBPPP) has the best antibacterial power so it was applied in the second stage of research. The results of the second stage of research showed that the addition of RBPPP had a significant effect (T<0.05) on feed consumption, had a very real effect (T<0.01) on egg weight, HDP, egg mass, feed conversion, IOFC, hemoglobin., erythrocytes and hematocrit. However, there was no significant effect (T>0.05) on egg yolk cholesterol and leukocytes. The addition of RBPPP at the 1% level has the potential to reduce feed consumption and feed convertion ratio, increase egg weight, HDP and egg mass, even though the IOFC value is lower than the control treatment or without RBPPP. The addition of RBPPP at a level of 1.5 % has the potential to reduce egg yolk cholesterol levels compared to other treatments. The addition of RBPPP up to a level of 1 % is able to increase and maintain hemoglobin and hematocrit levels in normal conditions. Apart from that, the addition of RBPPP at levels of 0.5 % and 1.5 % is able to increase and maintain erythrocyte and leukocyte levels in normal conditions.

Comparison of Bamboo and Wire Types of Battery Materials on the Welfare and Production Performance of Laying Hen

This research aimed to determine the comparison of types of battery materials for laying hens, specifically bamboo and wire, on the welfare and production performance of laying hens. The material for this research consisted of 100 laying hens of the ISA Brown strain aged 54 weeks. The variables observed included livestock welfare, which was assessed through behavioral aspects (eating, drinking, and resting), while the production performance variables observed included HDP (Hen Day Production), egg weight, egg mass, and FCR (Feed Conversion Ratio). The research method employed an experimental approach using the T-test (independent sample). Two treatments were used, each with 50 replications. The results of the research indicated that the difference in treatment using T1 (bamboo battery materials) and T2 (wire battery materials) affected livestock welfare and production performance. The research results demonstrated that the behavior of bamboo batteries was considered better in terms of livestock welfare because they were able to better prevent heat stress. In terms of production performance, wire batteries exhibited higher Hen Day Production (HDP) and were better at preventing disease than bamboo batteries. However, bamboo batteries had a higher egg weight due to the frequency of feeding chickens being higher than wire batteries. Improved sanitation management is necessary for batteries made from bamboo because they tend to more easily become a medium for the growth of germs, lice, and fungi, which can cause disease and result in decreased production performance.

Evaluation and Analysis of the Effects of Feed Supplements, Including both Organic and Inorganic Selenium, on the Production of Layer Eggs

This research aims to evaluate and analyze the provision of additional feed in the form of selenium (Se) on the performance of egg production produced by layers. This research took the main object in the form of 60 weeks old laying hens with the Isa Brown strain. The research was carried out using a Completely Randomized Design (CRD) method with Duncan’s advanced test. The results of this study explain that providing additional feed in the form of selenium (Se) in several doses has a very real influence on egg production performance (egg weight, feed intake, mortality, daily egg production, and FCR). The best dose of selenium was shown in treatment three (commercial feed + organic selenium dose of 150 grams/ton of inorganic selenium feed + vitamin E dose of 1000 grams/ton of feed). The presence of selenium and vitamin E given as additional feed for laying hens can increase egg weight, egg production, minimize mortality rates, and increase appetite.

The Effect of the Addition of Turmeric Flour and Ginger Flour on The Performance of Laying Hens

This study aims to see the production performance of laying hens fed with turmeric flour and ginger flour. The laying hens used were 80 with Isa Brown strain aged 32 weeks. The maintenance of laying hens in this study was carried out intensively (caged). During the study, chickens were fed twice daily at 08.00 WIB and 15.00 WIB. Feed is given in a measured manner, namely 120 g/head / Day. Drinking water is given in ad libitum measured. The parameters observed in this study are feed intake, hen day production, egg weight and feed conversion ratio. This study used a complete randomized design (CRD) with four treatments and four replications. They were given treatment through feed ration with the following details: P0 (feed), P1 (feed + 0.75% turmeric flour + 0.25% Ginger flour), P2 (feed + 0.25% turmeric flour + 0.75% Ginger flour) and P3 (feed + 0.50% turmeric flour + 0.50% Ginger flour). Giving turmeric flour and ginger flour into the feed had a significant effect on hen day production and egg weight (P<0.05) and no significant effect on feed intake and feed conversion ratio. From the results of this study, it can be concluded that adding turmeric flour and ginger flour can produce hen day production and high egg weight.

Comparison of production characteristics of BLRI-developed layer strain-2 (Shorna) with commercial ISA Brown

The existing research program was undertaken to associate the presentation of Bangladesh Livestock Research Institute (BLRI) settled layer strain-2 "Shorna" with a commercial strain (ISA Brown). To conduct this study, a total of 120 ISA Brown and 120 Shorna pullets were selected at chance from the prevailing batch at the age of twelve weeks. Birds were arranged in a completely randomized design, with six replications having 20 birds in each replication. Non-significant results were found in the case of feather sexing accuracy between two brown egg-laying strains. The egg weight and the egg mass production were found to be significantly (p < 0.05) higher in Shorna than in ISA Brown, whereas the egg production rate fell for Shorna compared to ISA Brown. In terms of body weight or feed consumption, there was no statistically significant difference between Shorna and ISA brown, and neither of the studied layer chickens had an impact on their FCR. Higher serum phosphorus and antibody titer levels were found in Shorna than in ISA brown (P<0.05). Additionally, the Shorna strain had more ovarian follicles than the ISA brown strain (P<0.05). Therefore, it may be assumed that these results prove Shorna is equivalent to an ISA brown laying chicken.

External and Internal Qualities of Chicken Eggs Early Production at Various Storage Times at Room Temperature

Eggs are one of the consumed foods that contain many essential amino acid nutrients such as lysine, tryptophan, and methionine. Egg quality can be seen from the storability of eggs after they are produced. This study aims to evaluate the effect of various storage lengths on the external and internal quality of chicken egg consumption of the Isa Brown strain at the beginning of production at room temperature. The research method is a Laboratories experiment using a Complete Randomized Design. The study treatment consisted of egg storage duration for 0 days (P0), 7 days (P1), 14 days (P2), and 21 days (P3) with 4 repeats and each test unit of 4 eggs. The research variables include external qualities: egg weight, egg index, shell weight, and eggshell thickness, then internal qualities: egg white index, yolk index, yolk color, and egg pH. The data obtained in this study were analyzed with ANOVA, if there are differences between treatments, then proceed with the the Least Significant Differenttest. The results showed that the duration of deviation had a very noticeable influence (P<0.01) on the external quality of the egg including:egg weight, weightand thickness of the eggshell, and no influence (P>0.01) on the egg index. The length of storage also has a very noticeable influence on the internal quality of eggs (P<0.01). Based on the results of the study, it can be concluded that the initial chicken eggs of production at a storage duration of up to 21 days at room temperature experience a decrease in external and internal qualities but still meet the Standards National Indonesia 3926:2008

Performance and Growth Curve Prediction of Crossbred Chickens from Crossing between Local Roosters and Layer Hens

Demand for crossbred chicken (Indonesian native chicken x laying hens) continues to increase. This study aimed to find the best-crossbred chicken resulting from crossing between local/native roosters and laying hens which produce the highest body weight up to eight weeks of age, and its growth prediction using the Gompertz function. Eighteen (18) native roosters (9 Bangkok roosters, 9 Pelung roosters) and 36 laying hens of strains Isa brown, Lohman brown, and Hyline brown (12 each) were used in this study to produce 360 crossbred chickens. Factorial 2x3 (two male local roosters versus three strains of laying hens) using a completely randomized design with 3 replications was applied in this study. The results showed an interaction between native roosters and layer hens on the body weight of crossbred chickens at eight weeks of age. Crossbred chicken from crossing between Pelung rooster and Isa brown layer hen was the best in body weight at eight weeks of age. This crossbred chicken would reach a mature weight of 3026.89 g with an inflection weight of 1113.53 g and an inflection age of 7.40 weeks. In conclusion, crossbred chicken from crossing between Pelung roosters and layer hens of Isa brown strain was the best crossbred with the highest body weight at eight weeks of age. This crossbred chicken could be an alternative for fulfilling the demand for local chicken in Indonesia because the slaughter age could be shortened from 8 months to 8 weeks.

Effect of follicle-stimulating hormone and luteinizing hormone levels on egg-laying frequency in hens.

Gonadotropins, for example, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are hormones that affect the reproductive process. In hens, optimal levels of FSH and LH can stimulate follicle growth fairly rapidly and thereby increase egg production through follicle development and increased ovulation. Follicle-stimulating hormone acts in the early stages of follicular growth, whereas LH acts on pre-ovulatory follicles. Normal follicular growth is the result of the complementary action of FSH and LH. Low FSH and LH levels result in the formation of follicles but a lack of egg production in chickens. This study aimed to investigate FSH and LH hormone levels from layer chickens with different egg-laying frequencies. Fifty blood serum samples were collected from 54-week-old ISA brown strain hens that were divided into five groups (with 10 hens per group) as follows: Hens that lay eggs (i) every day, (ii) once every 2 days, (iii) twice every 3 days, (iv) 3 times every 4 days, and (v) hens that do not lay eggs. Follicle-stimulating hormone and LH levels were measured in samples using an enzyme-linked immunosorbent assay, and the data were analyzed using multivariate analysis of variance. Follicle-stimulating hormone levels were significantly associated with the frequency of egg laying in ISA brown strain hens (p < 0.05); the highest FSH level (869.005 ± 149.194 pg/mL) was found in hens that lay eggs every day. In contrast, the highest LH level (51.386 ± 2.410 mIU/mL) was found in hens that lay eggs every 2 days. High level of FSH (869.005 ± 149.194 pg/mL) was associated with a high frequency of egg laying (every day) in ISA brown strain hens, and LH level of around 30.406 pg/mL was associated with daily egg laying in these hens.

Efficacy of dietary supplementary probiotics as substitutes for antibiotic growth promoters during the starter period on growth performances, carcass traits, and immune organs of male layer chicken.

Background and Aim:With the increased concerns about global protein supply, chicken meat, especially from male layer chicken, constitutes an alternative in terms of quality and carcass traits. Probiotics have been proposed for replacing antibiotic growth promoters (AGPs), which have been prohibited as poultry supplement feeds. The present study aimed to determine the efficacy of dietary supplementary probiotics during the starter period on growth performances, carcass traits, and immune organs of male layer chicken.Materials and Methods:In this study, one hundred and eighty 1-day-old male chicks from the strain ISA brown were used. They were divided into six groups according to the feed: 100% basal feed (T0), basal feed+2.5 g AGP/kg feed (T1), basal feed+probiotics 1 mL/kg feed (T2), basal feed+probiotics 3 mL/kg feed (T3), basal feed+probiotics 4 mL/kg feed (T4), and basal feed+probiotics 5 mL/kg feed (T5). Probiotics (Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium spp.) were given at a concentration of 1.2×109 colony-forming unit/mL. Virginiamycin was used as AGP. ISA brown layer chicken was treated for 21 days. Growth performances (body weight, feed consumption, and feed conversion ratio [FCR]), carcass traits (weight at slaughter, weight of the carcass, breast muscles, liver, lungs, kidneys, and heart), immune organs (spleen, thymus, and bursa of Fabricius), and non-edible organs (head, legs, and wings) were analyzed.Results:Probiotic supplementation at 4 and 5 mL/kg feed (T4 and T5) during the starter phase improved the body weight, FCR, and feed consumption. The weight at slaughter, weight of the carcass, breast muscles, and liver from the T4 and T5 groups were significantly greater than those in the other treatment groups. In addition, the weight of the heart, lungs, and kidneys was increased in the T1, T2, T3, T4, and T5 groups compared with that measured in the T0 group. Furthermore, there were significant differences regarding the immune organs between the T0 and the other treatment groups. The weight of the head, legs, and wings was also greater in the probiotic and AGP supplementation groups (T1, T2, T3, T4, and T5) than that in the basal feed group (T0).Conclusion:Probiotic (L. acidophilus, L. plantarum, and Bifidobacterium spp.) supplementation at 4 and 5 mL/kg feed during the starter period can be used to improve the growth, carcass traits, and weight of immune organs in male layer chicken.
