Microelements are important for stabilizing cell structures, but in deficient conditions they can stimulate alternative pathways and cause disease. This study was aimed to presents the monitoring data on the biogeochemical situation of pasture ecosystems in the Astrakhan region, southern Russia. Microelements in the collected samples from the pasture ecosystem, as well as the organs and tissues of Soviet Merino sheep, were determined by atomic absorption method. It was found a low level of microelements in soil, plants and forages of the ecosystem in the Astrakhan region. In addition, it was found a low level of microelements (selenium, iodine, and cobalt) in the organs and tissues of Merino sheep. Hypomicroelementosis in sheep leads to oxidative stress in animals, lower productivity and decrease the immunity of animals, which can be a predisposing for other diseases.

The study was aimed to evaluate the effect of age on the serum metabolite of female Brahman crossbred cattle raised extensively under the cattle-oil palm integrated s ystem for 3 months. Thirty calves aged 3-6 months, 30 heifers aged 12-18 months, and 30 cows aged 48 months which were clinically healthy were selected and used in this study. Blood samples were collected from coccygeal vein. The serum was separated by centrifugation and stored at -20 o C until the time of analysis. Blood samples were collected from coccygeal vein as much as 4 mL. Serum metabolites were determined using an autoanalyzer (The Roche/Hitachi Cobas 6000 analyzer). Serum concentration of ALB, Ca, P, Na, K, and Cl in calves were higher than heifers and cows (P<0.05), while serum creatinine, total protein, blood urea nitrogen (BUN) and globulin concentration in cows were higher than those of calves (P<0.05). Serum glucose concentration in calves and heifer was higher than that in cows (P<0.05). It could be concluded that the age factor must be considered in the interpretation of the results of the examination of the serum metabolites of Brahman crossbred cattle raised extensively in oil palm plantations.

Ascorbyl-6-palmitate (AP) was a lipid-soluble synthetic ester of ascorbic acid that has been used as a preservation agent for foods and as an antioxidant in cosmetics and related products. This study aims to investigate the effect of shearing management and ascorbyl palmitate administration on physiological and hematological profiles in under heat load Padjadjaran sheep. The physiological profile involves respiration rate (RR), Pulse rate (PR), and rectal temperature (RT). Twenty rams Padjadjaran 1 – 1,5 year-old, weighing between 25 to 47.5 kg used from sheep breeding station Purwakarta, West Java - Indonesia. There are two treatments level in this research, (1). Shearing divide into two groups, unshearing ( c 0 ) and shearing ( c 1 ); (2). AP administration also divides two groups, not given ( a 0 ) and given 400 mg each head daily ( a 1 ). The whole treatments were a 0 c 0 , a 0 c 1 , a 1 c 0 and a 1 c 1 . Heat exposure application was exposed to sunlight when the sheep exposed, the animal tethered by rope at the neck region. The sheep exposed to the sun when the ambient temperature at least 34 o C, 180 minutes each day, three days a week. The result showed that AP administration and shearing have interaction effects on RR, PR and RT. The level of glucose and total protein is affected by interaction effect of AP administration and shearing, while cholesterol affected to shearing. The conclusion , supplementing AP and shearing application could reduce the negative impact of heat stress on physiological and blood metabolite profiles of Padjadjaran sheep. Although the wool of local breed has not economic value, the shearing is regularly needed.

In this experiment, we investigated the effect of increasing levels of palm kernel meal containing α-β-mannanase replacing maize to growing-finishing hybrid duck on growth performance, nutrient digestibility, and carcass trait. One hundred and ninety- six hybrid ducks [(Peking x Khaki Campbell)] with 410.52 ± 95.25 g BW) were allotted to 5 dietary treatments with 9 ducks (unsexed) per pen and 4 replicates per treatments. These dietary treatments were: NC (negative control; maize-soybean-meal based diet), PKM25 (maize replacement with PKM α-β-mannanase 25%), PKM50 (maize replacement with PKM α-β-mannanase 50%), PKM75 (maize replacement with PKM α-β-mannanase 75%), PKM100 (maize replacement with PKM α-β-mannanase 100%). There was a curve linear decrease in the growing phase and finisher phase in feed intake as the level of α-β-mannanase palm kernel meal increased in the diet. Curvilinear, the result was presented no significant difference (P>0.05) on the initial body weight, growing and finishing phase body weight. The result of this study showed the used α-β-mannanase in the palm kernel meal presented a significant difference (P < 0.05) on the nutrient digestibility of dry matter and crude protein. Furthermore, Carcass traits showed the reflection in line with the final weight and internal organs were better to compare to control 0.5% using α-β-mannanase in the palm kernel meal. In summary, the increase of the level of palm kernel meal with α-β-mannanase enzyme was had a positive effect on the hybrid ducks and the replacement of palm kernel meal by 25% with the addition of the α-β-mannanase enzyme was able to improve digestibility and reduce abdominal fat of hybrid ducks.
在本试验中，我们研究了添加含α-β-甘露聚糖酶的棕榈仁粉代替玉米对育成杂交鸭生长性能、养分消化率和胴体性状的影响。将196只体重为410.52±95.25 g的杂交鸭[（Beijing x Khaki Campbell）]分配到5个日粮处理中，每个处理9只鸭（未固定），每个处理4个重复。这些日粮处理为：NC（阴性对照；玉米豆粕基日粮）、PKM25（用25%的PKMα-β-甘露聚糖酶替代玉米）、PKM50（用50%的PKMβ-甘露聚糖酶替代玉米），PKM75（用75%的PKM a-β-甘露糖酶取代玉米）、PKM100。随着日粮中α-β-甘露聚糖酶棕榈仁粉水平的增加，采食量在生长期和后期呈曲线线性下降。在曲线上，初始体重、生长期和结束期体重差异无统计学意义（P>0.05）。本研究结果表明，棕榈仁粕中使用的α-β-甘露聚糖酶对干物质和粗蛋白质的养分消化率有显著差异（P<0.05）。此外，胴体性状与最终重量一致，在棕榈仁粉中使用α-β-甘露聚糖酶与0.5%对照相比，内脏更好。综上所述，用α-β-甘露聚糖酶提高棕榈仁粉的水平对杂交鸭有积极影响，用添加α-β甘露聚糖酶的棕榈仁粉替代25%可以提高杂交鸭的消化率，减少腹部脂肪。

Artificial Insemination Center (AIC) produces frozen semen that was taken from superior bull. The selection of superior bull was based on breeding soundness evaluation. This study is aimed to evaluating the correlation between the molecular weight (MW) of seminal plasma protein and semen quality of Simmental bulls. Semen ejaculates from nine Simmental Bulls, that belong to AIC of Central Java, at Ungaran, were collected by using an artificial vagina. The sub population of sperm in ejaculates was evaluated through macroscopically and microscopically, in which the semen then centrifugated 6500 rpm for 30 minutes. The supernatant was collected and inserted into mini straw and stored in liquid nitrogen container. The concentration of seminal plasma protein was determined by the Bradford method. The Bradford protocol of analysis was suitable with User Guide Coomasize (Bradford) Protein Assay Kit. Thermo Skanlt RE for Multiskan Go Software, 3.2 version was applied for analyzing of the data, and protein characterization used was 1D-SDS-PAGE. The Coomassie Brilliant Blue was used for coloring the gels, and the proteins MW was determined by MW markers. The result demonstrated that there was no significant correlation between protein concentration and semen quality (P>0.05). Protein expressions based on MW were 62-48 kD, 100-71 kD found in this study. The analysis of correlation showed that the proteins with 100-71 kD MW correlated with sperm motility, normal sperm morphology, and sperm concentration. Semen quality in all parameters was significant (P˂0.05 and P>0.01) with 62-48 kD protein MW. The result concluded that seminal plasma protein had a correlation with semen quality and can be used as additional indicator for bull’s candidate selection.

The purpose of this study was to analyze the factors influencing the production and the efficiency of pig farming input in Minahasa Regency of North Sulawesi Province. The location was determined using the multistage random sampling method, determining regency, districts, and village, which have the highest pig population in North Sulawesi Province, so that Minahasa Regency, and four selected Districts (Sonder, Kakas, Tombulu and Tombariri), then 2 villages/district were taken. The sample was determined using a simple random method by taking 25 farmers in each district so that the total sample was 100 pig farmers, then the data was taken in January-July 2019. Variables measured were the number of pig production, the number of sows, the number of piglets, the number of feed (corn, concentrate, rice bran) and the number of labor. Data were analyzed using the Cobb-Douglas production function model with multiple linear regression and marginal product values calculations. The results showed that the efficiency of pig farming inputs was larger than one, meaning it was inefficient. This condition is still possible to increase pig production by increasing the number of sows, the number of piglets, the number of feed (corn, bran, concentrate), and the number of labor.

This study aimed to estimate natural increase (NI), net replacement rate (NRR), output, and population dynamics of Aceh cattle at Livestock Breeding and Forage Center in Indrapuri, Aceh province. Data of population structure, mortality, birth rate, the number of animals entering the herd, and the number of animals released from the herd during 2019 were used for determining NI and NRR , and it is used for estimation of output . P opulation structure data (2015-2019) were used to estimate the population dynamics. The results showed that NI was 19.08% (medium category). The availability of replacement stock exceeded the need for replacement (140.08% for male and 73.33% for female); the NRR was 240.08% (male) and 173.33% (female). The output of Aceh cattle was 3.92% (culled male), 5.58% (culled female); the remaining replacement stocks were 5.49% (male) and 4.09% (female) of the total population. The populatio n of Aceh cattle from 2020 to 2024 was expected to increase by 6.02% (65 heads) on average. In conclusion, that BPTU-HPT Indrapuri can be categorized as a beef cattle producing region, but still need efforts to increase natural increase by increasing birth rate minimum 32.77% and reducing mortality maximum 3.0%, in combination with better management systems.

The main objective of the investigation was to observe the growth performance, carcass yield, meat quality, and intestinal morphology of broiler chicks with respect to the dietary crude palm stearin (CPS). The study was conducted on 200 birds and dividing them into two experimental groups viz control and CPS treated group with 10 replications of 10 birds in each. Chicks under the control group were fed basal diet only, however in CPS treated group chicks were fed the basal diet supplemented with 3% CPS. Birds were reared for 42 days and data regarding different parameters of study was recorded. Data were analyzed by student T - test and differences were considered significant at P < 0 . 05 . Results indicated CPS treated group pertaining to lower final body weight, daily weight gain, feed conversion ratio, feed intake, dressing percentage, fillets, thight+drumsticks, and wings percentages. CPS treated group possessed lower liver, spleen, gizzard, and abdominal fat weights. Breast meat holds lower values for shear force, drip loss in CPS treated group, while cooking loss found vice versa. Abdominal fat breast in the meat and thigh skin possessed higher a* (redness) and b* (yellowness) values in CPS treated chicks, while breast skin and thigh meat hold lower a* and b* values in CPS treated chicks compared to control. Intestinal villus height, villus area and crypts depth in duodenum found considerably higher in the CPS treated chicks. Jejunum in CPS treated group possessed higher crypt depth but villus height and villus area remained lower. In conclusion, CPS impairs overall growth performance, carcass yield and meat quality but supports the intestinal morphology.
