Pelatihan Pemanfaatan Larutan Fenol Organik dalam Pakan untuk Meningkatkan Produktifitas Ternak Puyuh

One of the impacts of the Covid 19 pandemic is many people lose their jobs. Providing quail breeding training is one solution to getting a new job or business. Quail is a small poultry that can be raised in an urban area. However, the quail manure needs to be handled properly to prevent environmental problems. One of the solutions is to utilize organic phenolic compounds made from coconut waste, mixed in quail feed. Organic phenol solution is an innovation with the function of one of which is to improve the performance of quails. The feed nutrients consumed by quails can be absorbed more completely by using liquid organic phenol so that the odor from the waste produced will also be reduced and quail production performance can be optimal. The method used is the presentation of training materials, discussions, filling out surveys, as well as participatory activities from participants through direct practice of quail cultivation. After this training, there is an increase in public insight into handling waste from quail farming, as well as an increasing desire of the community to do quail farming. It can become a source of income or new jobs for the people of Cihideung Udik Village.

Research Note: Effect of Rubia cordifolia L. processed Terminalia chebula Retz polysaccharide on the histological structure and apoptosis in the spleen in immunosuppressed Chinese yellow quail

It is generally accepted herbal polysaccharide and is a bioactive compound of herbal medicines with immunomodulatory activities. It has a wide range of pharmacological effects. It can be used as a green substitute for antibiotics or as a feed additive in quail breeding. Therefore, the herbal polysaccharide has a broader and safer application prospect. The immunosuppressive disease of quail is one of the most important infectious diseases. It seriously affects the growth, development, and production performance of quail, causing huge economic losses to quail industry. However, there is no report on the effective alleviation of spleen injury in immunosuppressed animals by herbal polysaccharide. Therefore, we established a pathological model of immunosuppressive Chinese yellow quail for the first time, with the Terminalia chebula Retz polysaccharide (TCP) as the control, and histological observation, TUNEL staining were used to study the effects of Rubia cordifolia L. processed Terminalia chebula Retz polysaccharide (RTCP) on splenic tissue structure and apoptosis of immunosuppressed Chinese yellow quail. The experimental results showed that spleen organ index of the cyclophosphamide (CTX) group was significantly lower than these of blank control group, the TCP group and the RTCP group (P < 0.05). And the number of splenic nodules in the CTX group was significantly lower than that in the blank control group (P < 0.01). Compared with the CTX group, the spleen volume of the TCP group and the RTCP group increased, and the number and area of spleen nodules increased. Among them, the spleen nodules in the RTCP group were significantly more higher than that in the CTX group (P < 0.01). Meanwhile, TUNEL staining showed that the TUNEL positive cells in the CTX group were the most significantly higher than those in the blank control group (P < 0.01). TCP group and RTCP group were significantly higher than the blank control group (P < 0.01), but significantly lower than CTX group (P < 0.05). All these results suggested that RTCP could effectively improve CTX-induced spleen damage in immunosuppressed Chinese yellow quails by promoting the recovery of spleen organ index, repairing the spleen tissue structure, and diminishing the apoptosis. Moreover, RTCP is more effective than TCP. The results prove that the efficacy of RTCP in protecting spleen from CTX induced injury was enhanced after processing with Rubia cordifolia L. Therefore, our findings will provide more possibilities to promote the clinical application and development of processed traditional Chinese medicine in the further.

Expression of GnIH and its effects on follicle development and steroidogenesis in quail ovaries under different photoperiods

Photoperiod is an important environmental factor that influence seasonal reproduction behavior in bird and GnIH can play a function in this process through the reproductive axis, and some studies suggest that GnIH may have a direct role at the gonadal level. To investigate the expression of GnIH and its effects on follicle development and steroidogenesis in quail ovaries under different photoperiods, 72 healthy laying quails of 8-wk-old were randomly divided into long day (LD) group [16 light (L): 8 dark (D)] (n=36) and short day (SD) group (8L:16D) (n=36). Samples were collected from each group on d1, d11, d22, and d36 of the experiment. The result showed that short day treatment upregulated the level of GnIH in the gonads (P < 0.05), decreased the expression level of CYP19A1,3β-HSD, StAR, LHR, and FSHR and increased the expression level of AMH, AMHR2, GDF9, and BMP15 to inhibit follicle development and ovulation, thus affecting the egg production performance of quails. In vitro culture of quail granulosa cells and treatment with different concentrations of GnIH (0, 1, 10, and 100 ng/mL) for 24 h. Result showed that GnIH inhibited the levels of FSHR, LHR, and steroid synthesis pathways in granulosa cells, upregulated the levels of AMHR2, GDF9, and BMP15. The results suggest that the inhibition of follicle development and reduced egg production in quail by short day treatment is due to GnIH acting at the gonadal level, and GnIH affected the steroid synthesis by inhibiting gonadotropin receptors.

Yogurt as Probiotic: Comparative Effect on Growth Performance of Broiler Japanese Quail (Coturnix Japonica)

Yogurt is a natural source of gut-friendly bacteria. It has a considerable body of evidence that supports the significant positive effects of yogurt as probiotics on quail production performance and health. Yogurt containing bacteria can improve quail economic indexes and resistance to pathogens. With this objective, 240 growing Japanese quails were randomly distributed into three groups A1 (control), A2 (Yogurt), and A3 (Protexin) (4 replicates/treatment of 20 birds) to investigate the effect of yogurt as a probiotic source. Birds were allowed to be fed ad libitum with a commercial quail ration. Yogurt and Protexin were mixed at the rate of 5 ml/L (5ml into 1 lt. water) and 1g/L (1gm into 1 lt. water) in A2 and A3, respectively. Six (6) weeks of investigation showed a significantly higher result in yogurt than in the other two groups. Body weight had a significant difference between the control and protexin groups. Body weight gain (g) was significantly heavier in A2 at the finisher phase. No significant effect was observed in feed intake, but FCR (Feed Conversion Ratio) was significantly lower in A2, but no significant effect was noticed between A1 and A3. The mortality percentage was higher in the control group (2.66%) and lowest in yogurt (1.03%). Carcass characteristics were significantly heavier in A2 than A1 and A3. Non-carcass characteristics illustrated significant differences among the three groups, but a non-significant difference was observed in head weight. The gross return per bird was higher in A2 (12.05 BDT), whereas it was 6.55 BDT and 7.08 BDT for A1 and A3. With those observations, it can be concluded that yogurt successfully enhanced overall broiler performance and gross return of Japanese quail.

Effects of Dichrostachys glomerata Feeding Regimes on Growth Performance, Gut Microbiota and Haemato-Biochemical Profile of Japanese Quails

Background: The ban of antibiotics growth promoters due to bacteria resistance and the presence of chemical residues in animal products have stimulated research for alternative feeding supplements in poultry production. This study was designed to assess the production performance of quails under two D. glomerata feeding regimes. Methods: A total of 160 two weeks old Japanese quail chicks were assigned to four experimental treatments in a completely randomised design with 4 replicates of 10 chicks (5 males and 5 females) in each treatment. The two feeding regimes consisted of 5 g/kg of feed (T1) and cold water inclusion of 5 g/l (T2) of D. glomerata. Data were recorded on feed intake, weight gain, feed conversion ratio, haematological and serum biochemical parameters, and intestinal microbial count. Findings: Quails fed on the two feeding regimes were compared to quails fed with diet without any supplement (T0) and an antibiotic (1 g/kg) medicated diet. The results showed no significant difference (p>0.05) in feed intake and weight gain, however the feed conversion ratio was significantly lower (p 0.05) effect on carcass yield and relative weight of organs. Triglycerides concentration was significantly higher in quails fed on cold water administration of D. glomerata as compared to the control diet. Aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), creatinine, total protein, albumin, urea, total cholesterol, HDL-cholesterol and LDL-cholesterol were not significantly affected by the feeding regimes. Except for the concentration of pack cell volume (PCV) that was significantly high (p<0.05) with cold water administration (41.5%) as compared to the negative control ration (35.25%), haematological blood components were not significantly affected by the feeding regimes. Feeding quails with D. glomerata powder whatever the regime significantly (p<0.05) increased lactic bacteria count compared to E. coli, Salmonella and Staphylococci. Conclusions: The feeding of D. glomerata powder to quails through feed or drinking water can be used as an alternative to antibiotics to balance gut microbiota in Japanese quails.

Effect of feed supplement containing earthworm meal (Lumbricus rubellus) on production performance of quail (Coturnix coturnix japonica)

The objective of this study was to evaluate the effect of feed supplement (FS) contained earthworm meal (EWM) on production performance of laying quails. Twenty weeks-old of 360 Coturnix coturnix japonica quails were used in a Completely Randomized Design (CRD) with three dietary treatments A = CD (control without FS), B = CD + 0.250 % of FS, and C = CD + 0.375 % of FS during 6 weeks of experimental period. Each treatment in 4 equal replicates in which 30 quails were randomly allocated into 12 units of cages. Variable measured were feed intake, feed conversion ratio, feed efficiency, mortality rate, hen day production, egg weight, and egg uniformity. Data were statistically analyzed by One Way ANOVA and the differences among mean treatments are analysed using Duncan’s Multiple Range Test (DMRT). The results showed that administration of 0.375% FS based on earthworm meal, fermented rice bran, and skim milk impaired the feed conversion ratio and increased the feed efficiency. The experimental treatments did not effect on feed intake, mortality, hen day production, egg weight, and egg uniformity of quail. It is concluded that administration of feed supplement improved the growth performance of quail.

The importance of propolis in alleviating the negative physiological effects of heat stress in quail chicks.

Heat stress is one of the most detrimental confrontations in tropical and subtropical regions of the world, causing considerable economic losses in poultry production. Propolis, a resinous product of worker honeybees, possesses several biological activities that could be used to alleviate the deleterious effects of high environmental temperature on poultry production. The current study was aimed at evaluating the effects of propolis supplementation to Japanese quail (Coturnix coturnix japonica) diets on the production performance, intestinal histomorphology, relative physiological and immunological parameters, and selected gene expression under heat stress conditions. Three hundred one-day-old Japanese quail chicks were randomly distributed into 20 wired-cages. At 28 d of age, the birds were divided into 2 temperature treatment groups; a normal at 24°C (C group) and a heat stress at 35°C (HS group). The birds in each group were further assigned to 2 subgroups; one of them was fed on a basal diet without propolis supplementation (-Pr subgroup) while the other was supplemented with propolis (+Pr subgroup). Production performance including body weight gain, feed intake and feed conversion ratio were measured. The intestinal histomorphological measurements were also performed for all treatment groups. Relative physiological parameters including body temperature, corticosterone hormone level, malondialdehyde (MDA) and free triiodothyronine hormone (fT3), as well as the relative immunological parameters including the total white blood cells count (TWBC’s), heterophil/lymphocyte (H/L) ratio and lymphocyte proliferation index, were also measured. Furthermore, the mRNA expression for toll like receptor 5 (TLR5), cysteine-aspartic protease-6 (CASP6) and heat shock proteins 70 and 90 (Hsp70 and Hsp90) genes was quantified in this study. The quail production performance was significantly (P<0.05) impaired by HS treatment, while Pr treatment significantly improved the quail production performance. The villus width and area were significantly (P<0.05) lower in the HS compared to the C group, while Pr treatment significantly increased crypts depth of quail. A negative impact of HS treatment was observed on the physiological status of quail; however, propolis significantly alleviated this negative effect. Moreover, quail of the HS group expressed lower immunological parameters than C group, while propolis enhanced the immune status of the quail. The relative mRNA expression of TLR5 gene was down-regulated by HS treatment while it was up-regulated by the Pr treatment. Furthermore, the positive effects of propolis in HS-quail were evidenced by normalizing the high expressions of CASP6 and Hsp70 genes when compared to the C group. Based on these results, the addition of propolis to quail diets as a potential nutritional strategy in order to improve their performance, especially under heat stress conditions, is recommended.

Production performance of quails given chromium organic in ration

Egg production of quails depends on quality of ration. Nutrient manipulation by chromiun inclusion in ration is a possible way to improve production. It is known that chromium mineral in form of GTF in blood has a role not only in enhancement of glucose entering cells through improvement of insulin activity but also in metabolism of lipid and synthesis of protein and elimination of heat stress to improve egg production. This study aimed at assessing egg production of quails fed ration containing chromium-yeast. Sixty-four quails aged 40 days were used. A completely randomized design with 4 treatments and 4 replication was applied in this study. Treatment consisted of commercial ration + Cr 0 ppm (R1), commercial ration + Cr 0.5 ppm (R2), commercial ration + Cr 1 ppm (R3), and commercial ration+ Cr 1.5 ppm (R4). Measurements were taken on feed intake, egg weight, egg mass production, hen day, feed conversion rate, egg index, and egg shell thickness. Results showed that A ration containing organic chromium as much as 1,5 ppm did not affect feed intake , egg production, egg weight , and eggshell thickness, however lowered feed conversion rate by up to 32.25% from that of control. Supplementation of 0,5 ppm chromium in the ration lowered the value of eggs index in the fourth week.
