The organic zinc was supplemented into basal diet at different concentrations as follows; (T1) 0, (T2) 100, (T3) 200, and (T4) 300 mg/kg. The results showed T2 was recorded improvement significant on FI, and FCR followed by T3. Also, egg mass in T2 was increased significantly compared with T1. The T2 and T3 were significantly higher in average egg production as compared to T1 which was showed the lowest value. There was no significant effect on egg quality when supplemented organic Zn to the diet of layer hens. It might be concluded that the dietary supple-mentation of 100 mg/kg of organic Zn has improved feed consumption which is reflected in the produc-tivity of laying hens.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48230733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even pigs occupy the top rank in contributing to Indonesia's live animal exports. The purpose of this study was to com-pare the level of technical efficiency of smallholder piglet production farming in three centers of pig production areas, namely North Sumatra, Bali, and East Nusa Tenggara (NTT). The research data was sourced from secondary data at the farm level, collected by the Central Statistics Agency of Indonesia, through the Livestock Business Household Survey. This research utilized the stochastic production frontier model to assess the production efficiency and the one-step maximum likelihood estimation (MLE) method to measure the level of technical efficiency and the significance of the factors. The re-sults show that the average level of technical efficiency of piglet production farms in Indonesia is rela-tively low. Piglet production farms in Bali have the highest efficiency level and NTT is the lowest of the three provinces being compared. The number of pigs, feed expenditure, capital, and vaccinations are important factors in influencing production and the level of technical efficiency. Public policies that can increase farmers' access to production factors and better pig farm vaccine management become a necessity.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42097804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two hundred and twenty four (224) mixed sexes Abor – acre day old chicks were subjected to trial for 6 weeks. Data were collected on performance, haematology, serum biochemistry, serum electrolytes and organ morphology. The birds were randomly assigned to 7 dietary treatments: T1: control with commercial vitamin-mineral-premix (VMP) at 0.3% only, T2, 0.05% CPS + 0.25 VMP, T3 0.20 VMP + 0.1 CPS, T4 0.15 VMP + 0.15 CPS, T5 0.10 VMP + 0.2 CPS, T6 0.05 VMP + 0.25 CPS and T7 0.3 CPS. Treatments composed of 4 replica-tions with 8 birds per replicate. Results indicated that significant differences (p<0.05) were observed in all the treatments for WG, FCR and FI. Birds fed with 0.3% of CPS had the best FCR. At the starter phase, significant differences (p<0.05) were observed in the haematology of the birds, however, the values obtained for hemoglobin, white blood cell and eosinophils were not significantly different (p>0.05) while at the finisher phase, the inclusion of Carica papaya seed meal significantly influenced (p<0.05) the values of haematology, the values were however higher (p<0.05) at higher levels of inclu-sion except for white blood cells (WBC) and platelets counts that the control group had significantly higher (p<0.05) values. There was no significant difference (p>0.05) in serum biochemistry parameters at the starter phase except for alanine transaminase (ALT) with significantly higher (p<0.05) value at the control but significantly affected (p<0.05) all the serum biochemical parameters at the finisher phase. Birds fed CPS had significantly higher (p<0.05) values for glucose, cholesterol and low density lipoprotein (LDL). However, birds fed 0.20% CPS had significant highest (p<0.05) values for ALT, Alanine phosphatase (ALP), glucose, cholesterol, LDL and high density lipoprotein (HDL). CPS sig-nificantly influenced (p<0.05) serum electrolytes. Birds in 0.05 and 0.10% CPS inclusion groups had significantly higher (p<0.05) values for sodium, chloride and bicarbonate ions when compared to the control. There was no significant difference (p>0.05) for kidney, liver and spleen. The use of CPS did not impair nutrient utilization neither does it have any adverse effect on the health status of the broiler chickens, hence the use of CPS may be considered as substitute for vitamin-mineral premix in broiler chickens nutrition.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45852614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to investigate the association between polymorphism of PRL gene and egg production traits in Alabio and Mojosari Ducks. Genomic DNA were isolated from 111 blood samples (51 Alabio and 60 Mojosari). PCR and sequencing were performed to identify poly-morphisms and genotype of the animals. Data recording of the ducks including body weight at 16 weeks of age and at first egg, average weight of three first eggs laid and egg number laid up to 3, 6 and 12 months production were collected. Data were analyzed using independent sample t-Test. As a result, two single nucleotide polymorphisms (SNP) were detected in intron 4. Both SNP C-5796A and SNP T-5817C were found to have association with egg number laid up to three months (P<0,005). The CA/TC genotype had higher egg number than CC/TT. These suggested that SNP C-5796A and SNP T-5817C could be potential markers for marker assisted selection to increase egg number in duck.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43775838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One hundred fifty-six hens and twenty-four cocks of WL at twenty-four weeks of age were randomly dis-tributed to four treatments, each replicated three times with thirteen layers and two cocks per replication and kept on a deep litter system. Treatment rations were formulated by the addition of Khat leave on layers ration with the proportion of 0% (T1), 0.2% (T2), 0.4% (T3), and 0.6% (T4). All data were subjected to analysis of variance. The egg weight of layers in T3 (54.1) was higher (P<0.05) than that of layers in T4 (51.5) and T1 (51.8). Roche color reading was significantly higher for T4 (4.7±0.19) than T3 (3.4±0.19), T2 (2.2±0.19), and T1 (1.7±0.19). There were no significant differences (P > 0.05) among treatments in yolk height, yolk index, yolk diameter, albumen height, Haugh unit, fertility, hatchability, chick weight, and visual score. Embryonic mortality percentage was significantly (P<0.05) higher for T1 than for other treatments. Chick length was significantly (p<0.05) higher in T2, T4, and T3 than in T1. Finally, this study can be concluded that the use of dried Khat leaves as an additive up to 0.6% in ration of White Leghorn layers increased eggshell weight and yolk coulor and reduced embryonic mortality.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47235880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known that CO2 derived from human respiration can be used as alternative support for IVM of oo-cytes. However, this method is categorized as using a suboptimal culture environment, and it results in increased production of reactive oxidative species (ROS). Thus, the addition of the antioxidant GSH is needed. In total, 273 oocytes were cultured in three groups: 5% CO2 (control) and CEbH with 0 mM and 1 mM of GSH addition, respectively. The results showed that the control group produced a better maturation rate (p < 0.05) compared to the remaining two groups (65.92% vs. 24.44% and 30.61%), which used CEbH. Statistically, 0 mM GSH vs. 1 mM GSH did not show any significant differences (p > 0.05). However, 1 mM GSH led to more mature oocytes (24.44% vs 30.61%) compared to the group without GSH. In conclusion, IVM using CEbH supports oocyte maturation, and the addition of GSH can improve the maturation rate in a suboptimal culture environment.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46535967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, the study was carried out with a descriptive-transversal methodology with a non-experimental design and quantitative approach, where the survey was applied to 44 swine production units through a non-probabilistic method. The data were systematized using R software; a principal component analysis was performed and the degrees of relationship of socio-economic factors with the use of NTFPs in animal feed. It was concluded that despite being in a biodiverse territory, social factors related to the level of knowledge about NTFPs and economic factors linked to sources of financing are directly proportional to the degree of NTFP use in swine production in the department of Caquetá. Although NTFPs are found in most production systems in the region, they are not used for animal feed.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43426200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main parameters observed were DMI, BWG, carcass (CWG) and meat weight gain (MWG), and methane emission. The results showed, the young goat fed G3C7 was higher than that fed G7C3 in DMI. The BWG’s of goats fed G3C7 were higher than those fed G7C3, but there was no difference between ages in BWG. The FCR of young goat fed G3C7 was lower than that fed G7C3. The DMI of mature goat was higher than young goat, but there were no differences between the ages in DM digestibility, carcass weight and meat weight gain. The young and mature goats fed G3C7 was significantly lower than that of G7C3 in methane emissions per unit of BWG (0.28 vs 0.40 and 0.36 vs 0.53, respectively), in methane emissions per unit CWG (0.60 vs 0.93 and 0.79 vs 1.47, respectively), and methane emission per unit MWG (0.89 vs 1.42 and 1.16 vs 2.19, respectively).
