This study was carried out to determine the dietary supplementation of organic zinc on feed intake (FI), feed conversion ratio (FCR), egg production (EP), egg mass (EM) and quality. A total of 120 ISA-Brown layers aged 20 weeks were used in this study. Hens were distributed randomly to four treatments (30 hens of each) with three replicates. 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.

Pork production occupies the third position in Indonesia, after chicken and beef. 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.

The study investigated the physiological response of broiler chickens to substitution of commer-cial vitamin-mineral premix with Carica papaya seed meal (CPS). 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.

Prolactin (PRL) affects egg production in duck as it induces broodiness and promotes follicles development. 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.

An experiment was conducted to evaluate the effects of supplementation of Khat leave as a natural feed additive on egg quality, fertility, embryonic mortality, hatchability, and chick quality of White Leghorn (WL) layers. 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.

This study aimed to identify the effect of the use of CO2 exhaled by human (CEbH) in in vitro maturation (IVM) with the addition of Glutathione also known as GSH on the oocytes maturation rate. 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.
本研究旨在确定在体外成熟(IVM)中使用人呼出的二氧化碳(CEbH)并添加谷胱甘肽(GSH)对卵母细胞成熟率的影响。众所周知，人类呼吸产生的二氧化碳可作为卵母细胞IVM的替代支持。然而，这种方法被归类为使用次优培养环境，它会导致活性氧(ROS)的产生增加。因此，需要添加抗氧化剂谷胱甘肽。共培养273个卵母细胞，分为3组:5% CO2(对照)和CEbH，分别添加0 mM和1 mM GSH。结果表明，对照组的成熟率高于其余两组(65.92% vs. 24.44%和30.61%)，p < 0.05。统计学上，0 mM GSH与1 mM GSH差异无统计学意义(p < 0.05)。然而，与没有GSH的组相比，1 mM GSH导致更多的成熟卵母细胞(24.44%对30.61%)。综上所述，使用CEbH的IVM支持卵母细胞成熟，并且在次优培养环境下添加GSH可以提高成熟率。

In view of the difficulties present in the swine production system to achieve sustainable productivity based on the comparative advantages and potential of the territory of the department of Caquetá, located in the natural region of the Colombian, the aim of the study was to analyze the socioeconomic factors that may influence the use of non-timber forest products (NTFPs) in live-stock feed. 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.

This study was conducted to determine the effects of herb residues on carcass and meat quality in broilers. A total of 160 chicks were divided into four groups, each with four replicates of 10 chicks; the chicks were provided ad libitum access to a control diet or the same diet supplemented with Zingiber cassumunar, Kaempferia galangal, or Curcuma aromatica residues at 0.3% feed. At 42 days of age, 20 chicks from each group were slaughtered, and the carcass and meat quality were determined. All exper-imental groups demonstrated lower abdominal fat weight, and the K. galangal group had a significantly higher total visceral organ weight than that of the control group (P<0.05). The experimental groups demonstrated improved color of the breast muscle, breast fillet muscle, skin, and abdominal fat (P<0.05). The shear force value of the breast muscle increased in the K. galangal group, whereas that of the thigh muscle increased in all experimental groups (P< 0.05). The highest overall acceptability of raw and cooked chicken breast meat was produced by 0.3% C. aromatica residue supplementation (P<0.05). These finding suggest that the inclusion of 0.3% C. aromatica residue in the diets resulted in improved overall acceptability of breast meat without negatively affecting dressing percentage.

At 42 days of age, 20 chicks from each group were slaughtered, and the carcass and meat quality were determined. All exper-imental groups demonstrated lower abdominal fat weight, and the K. galangal group had a significantly higher total visceral organ weight than that of the control group (P<0.05). The experimental groups demonstrated improved color of the breast muscle, breast fillet muscle, skin, and abdominal fat (P<0.05). The shear force value of the breast muscle increased in the K. galangal group, whereas that of the thigh muscle increased in all experimental groups (P< 0.05). The highest overall acceptability of raw and cooked chicken breast meat was produced by 0.3% C. aromatica residue supplementation (P<0.05). These finding suggest that the inclusion of 0.3% C. aromatica residue in the diets resulted in improved overall acceptability of breast meat without negatively affecting dressing percentage.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47872477","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}

In case of livestock development in the rural areas of Tra Vinh province of Vietnam, Muscovy duck breeds are diversified by importing and breeding, which is more valuable for social and economic benefits. A total of 7,921 Muscovy ducks were observed to collect data for this survey to identify the current status of its production, feeding, and performance. Farmers, who owned at least 30 ducks, were interviewed to analyze data ownership, feeding, and growth performance of three breeds relating to the Muscovy including local Muscovy ducks (LMDs), France Muscovy duck (FMDs), and Crossbred Muscovy ducks (CMDs). The findings indicated that most farmers kept a small duck herd of fewer than 100 heads per householder, and the majority of Muscovy duck was LMDs. Farmers fed them local feed resources, with low nutritive diets (CP: 7.35 – 12.0 % and ME: 11.44 - 11.83 MJ/kg DM). A small number of farmers used a concentrate feed (CP: 16.5-19.3; ME: 11.96-12.69 MJ/kg DM) for supple-mentation with the daily weight gain was 16.7 g for LMDs and 22.7 g for CMDs, whilw the FMDs was fed a better quality of concentrate and gave the daily gain of 25.7 g.

An experimental study was carried out to evaluate the implication of early fattening of Kejobong goats by improving feeding quality on methane production and meat production. Sixteen goats (8 young and 8 mature) were raised for 4 months study period. Nested design was used in this study, with young and mature as a nest factor, and diet (G7C3: 70% grass and 30% concentrate and G3C7: 30% grass and 70% concentrate) as the treatments. 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). It can be concluded that fattening young Kejobong goats by improving feed quality is more environmentally friendly than fattening the mature ones.
通过提高饲养质量，评价了克孜邦山羊早期育肥对产甲烷量和产肉量的影响。饲养了16只山羊（8只幼山羊和8只成熟山羊），为期4个月。本研究采用嵌套设计，以幼龄和成熟期为嵌套因子，以日粮（G7C3：70%草和30%精料，G3C7：30%草和70%精料）为处理。观察到的主要参数是DMI、BWG、胴体（CWG）和增重（MWG）以及甲烷排放。结果表明，饲喂G3C7的山羊DMI高于饲喂G7C3的山羊。饲喂G3C7的山羊的BWG高于饲喂G7C3的山羊，但不同年龄组的BWG没有差异。饲喂G3C7的幼山羊FCR低于饲喂G7C3的幼山羊。成熟山羊的DMI高于幼山羊，但不同年龄组的DMI消化率、胴体重量和增重没有差异。喂养G3C7的幼山羊和成熟山羊的单位BWG甲烷排放量（分别为0.28 vs 0.40和0.36 vs 0.53）、单位CWG甲烷排放（分别为0.60 vs 0.93和0.79 vs 1.47）和单位MWG甲烷排放率（分别为0.89 vs 1.42和1.16 vs 2.19）显著低于G7C3。可以看出，通过提高饲料质量育肥幼龄克孜邦山羊比育肥成熟山羊更环保。
