TL;DR: It is concluded that Powdering method of earthworm by using formic acid addition had higher amino acid balance than earthworm.
Abstract: Earthworm meal (Lumbricus rubellus) has become one of natural material that could be used asfeed additive. Powdering method of earthworm was done by using formic acid addition. The study wascarried out (1) to evaluate the essential amino acid profile of earthworm and earthworm meal, (2) tocalculate the value of essential amino acid index (EAAI) of both materials. A modified EAAI equationwas developed from the essential amino acid profile of earthworm and earthworm meal. The resultshowed that essential amino acid of earthworm was dominated by histidine (0.63% of dry matter basis),meanwhile the earthworm meal was dominated by isoleucine (1.98% of dry matter basis). The nonessential amino acid of earthworm and earthworm meal was dominated by glutamic acid (1.52% and3.60% of dry matter basis respectively). The value of essential amino acid index obtained fromearthworm meal was higher (58.67%) than those from earthworm (21.23%). It is concluded thatpowdering method of earthworm by using formic acid addition had higher amino acid balance thanearthworm.

TL;DR: Turmeric extract seemed to be able to improve the digestion and metabolism resulted in enhanced production of hemoglobin in broilers, which might explain why turmeric could not improve thefeed efficiency of broiler.
Abstract: The experiment was carried out to investigate the effect of turmeric extract on blood parameters,feed efficiency and abdominal fat content in broilers. A total of 100 mixed-sexes Lohman chicks wereused in the experiment set up with completely randomized design of 5 different doses of turmeric extractgiven orally start from day-15 to day-35. The chicks given no turmeric extract were used as a control(T0), whereas T1, T2, T3 and T4 were the chicks given turmeric extract of 200, 400, 600 and 800mg/kg-live BW, respectively. Hemoglobin values of broilers given turmeric extract 800 mg/kg-live BWwas significantly higher (p 0.05)the concentration of erythrocytes, the levels of hematocrit as well as FCR and abdominal fat content ofbroiler. Turmeric extract seemed to be able to improve the digestion and metabolism (of fat) resulted inenhanced production of hemoglobin in broilers. The hypolipidemic effect of turmeric that could hamperits potential to promote the growth of broilers per se might explain why turmeric could not improve thefeed efficiency of broiler.

TL;DR: It was concluded that supplementation of turmeric powder with the level of 54 mg/quail/daydecreased lipid content of the egg and improved the other egg quality parameters.
Abstract: This experiment was conducted to determine the role of turmeric powder in lipid metabolism andits influence on the quality of the first quail’s egg. Sixty female quails were assigned into a completelyrandomized design with four treatments (levels of turmeric powder i.e., 0; 13.5; 27; and 54mg/quail/day) and each treatment used 15 quails. The treatment was conducted for 60 days. Parametersmeasured were proximate analysis and the quality of the first layed eggs. At the end of the experiment,serum cholesterol and triglyceride concentrations, abdominal and pectoral fat weights, and feedconsumption were measured. Chemical analysis showed that turmeric powder contained 7.97%curcumin. Supplementation of turmeric powder lowered serum cholesterol and triglycerideconcentrations, egg fat and protein contents, haugh unit and yolk index, but did not affect feed intake,abdominal and pectoral fat weights, egg weight, eggshell weight, eggshell thickness, and egg shellindex. However, quails supplemented with turmeric powder showed a variation in egg laying delayranging from 1 to 16 days. Quails supplemented with 54 mg/d turmeric powder had the highest follicleshierarchy. It was concluded that supplementation of turmeric powder with the level of 54 mg/quail/daydecreased lipid content of the egg and improved the other egg quality parameters.

TL;DR: In this article, the authors evaluated chemical composition, in vitro rumen fermentation, digestibility and methane emissions of some insects, i.e., Jamaican field cricket (JFC), mealworm (MW) and black soldier fly larvae age 1 and 2 weeks (BSF1 and BSF2).
Abstract: This experiment was aimed to evaluate chemical composition, in vitro rumen fermentation, digestibility and methane emissions of some insects, i.e. Jamaican field cricket (JFC), mealworm (MW) and black soldier fly larvae age 1 and 2 weeks (BSF1 and BSF2). Insect samples were oven-dried at 60 o C for 24 h, and ground to pass a 1 mm sieve. The ground samples were used subsequently for chemical composition determination and in vitro rumen fermentation test. Incubation was carried out in a water bath maintained at 39 oC for 48 h in three replicates. Results revealed that all insect meals contained high crude protein, i.e. above 40% DM. Proportions of neutral detergent insoluble CP ( NDICP) and neutral detergent insoluble CP ( ADICP) were high in the insect meals than that of soybean meal (SBM), and these were particularly very high in BSF2. All insect meals had lower IVDMD and IVOMD than that of SBM (P<0.05). All insect meals had lower methane emissions as compared to SBM at 12, 24 and 48 h (P<0.05). It can be concluded that insect meals are potential protein supplements and have low methane emissions in vitro . However, their digestibility is rather low and may limit their utilization.

TL;DR: Results showed no polymorphisms were detected in these genes in buffalo, and all buffaloes tested had LL genotype forlocus GH|AluI and AA genotypes for locus GHR|ALUI.
Abstract: Growth hormone (GH) is an anabolic hormone which sintesized and secreted by somatrotop cell inpituitary anterior lobe. GH exert its effect on growth and metabolism by interacting with a specificreceptor on the surface of the target cells. Growth hormone receptor (GHR) has been suggested ascandidate gene for traits related to meat production in Bovidae. The objectives of this study were toidentify polymorphism of GH and GHR genes in buffalo. The 452 DNA samples buffalo were collectedfrom five populations in Indonesia (Siborong-Borong-Medan (65), Lebak-Banten (29), Pandeglang-Banten (180), Semarang-Central Java, and Mataram-West Nusa Tenggara (103)). A gene fragment of theGH|AluI gene at 432 bp located on exon 3 and GHR|AluI gene at 298 bp on exon 10 were successfullyamplified by using the techniques of a PCR (polymerase chain reaction) and genotyped by PCR-RFLP(restriction fragment length polymorphism) then -SSCP (single strand conformation polymorphism). Theresults showed no polymorphisms were detected in these genes. All buffaloes tested had LL genotype forlocus GH|AluI and AA genotype for locus GHR|AluI.
