Fat Yield

The biochemical component (protein content and fat content) of soybean seed, yield and fat and protein yield significantly depends on weather conditions and variety. It was found that the protein content in soybean seed, on average over two years of research on new varieties can vary from 36.1 to 44.4 %. Khana, Lenka and Alaska varieties have the highest protein content in soybean seed – 43.4–44.4 %. Protein content significantly depends on the weather conditions of the study year. Thus, soybean varieties of Kofu, Siberia, Volta, Asuka, Arisa, Khana, Lenka and Alaska, grown in 2020, have this figure 10–19 % higher than in 2019. In the seeds of Nordica, Carra, Kyoto, Ezra, Amadeus and Taurus soybean varieties, the protein content is 4–10 % lower. On average, over two years of research, the fat content in soybean seeds varies from 18.9 to 21.7 % depending on the variety. Only three out of 14 soybean varieties have the fat content ≤ 20.0 % – Khana, Alaska, Arisa. In seeds of other varieties, this figure is ≥ 20 %. Weather conditions reduce the fat content in the seeds by 7–20 % depending on the variety. Studies have shown that soybean seed yields vary significantly depending on the soybean variety. Thus, on average over two years of research, this figure varies from 1.30 t/ha in Amadeus variety to 1.88 t/ha in Siberia one. The highest yields (≥ 1.70 t/ha) were formed by Arisa, Volta and Siberia varieties. However, this figure varies greatly depending on the weather conditions of the study year. Thus, in a more favourable 2019, the yield is from 1.65 to 2.41 t/ ha, depending on the soybean variety. Moisture deficiency and small reserves of moisture in the deeper layers of the soil reduce seed yield from 0.95 to 1.35 t/ha or by 1.7–3.7 times, depending on the soybean variety. Two soybean varieties (Arisa, Siberia) have the highest protein yield at the level of 706–721 kg/ha. The highest fat yield was obtained by Siberia growing – 415 kg/ha. Under the conditions of the Right Bank forest-steppe, for stable formation of high protein yield in different weather conditions, it is necessary to grow Arisa soybean variety which has high protein content and high seed yield, and Alaska variety which has high protein content in seeds. In addition, in the best hydration years it is able to form a high fat yield. Volta, Asuka, Khana and Lenka varieties should be grown in years with sufficient moisture, as they provide the highest protein yield. These varieties should also be grown to obtain a high fat yield under the best moisture conditions. Siberia soybean should be used to produce fat in different weather conditions

This study aims to determine the correlations between the test-day milk yield (TDMY) and the fat and protein content as well as the fat and protein yields in Holstein dairy cows and to investigate the effects of lactation period and sampling season on these parameters. The study material consists of 1.380 records of a total of 151 head of Holstein dairy cows raised on a private farm in Samsun province. In the study, the mean TDMY, fat content, protein content, fat yield and protein yield were recorded as 20.6±5.10 kg, 3.97±0.734%, 3.23±0.276%, 0.81±0.210 kg and 0.66±0.160 kg, respectively. The effects of lactation period and sampling season on the TDMY, fat content, protein content, fat yield and protein yield were found statistically significant (Pis less than 0.01). Statistically significant negative correlations were determined between the TDMY and the fat and protein content, but positive and statistically significant (Pis less than 0.01) correlations between the TDMY and the fat and protein yields. In conclusion, it might be stated that the effects of lactation period and sampling season should also be taken into account to improve milk yield and milk components.

The study was conducted in high productive herd of Holstein breed in JV "Agrosvit" Myronivka district, Kyiv region by retrospective analysis of the primary materials of zootechnical and pedigree records. The research involved analysis of data about 78 cows imported from Hungary to the farm in 2000 and 2003 and the first calving was during 2002-2004 and 117 cows imported from Denmark in 2005, the first calving was during 2005-2006. In comparison to the imported cows, contemporaries of local reproduction were selected based on respective years of the first calving (n = 409). The selection of animals and computing performance were conducted by the method of Polupan Yu. (2010). The aim of the research was a comparative study of economic use duration and lifetime performance of the imported Holstein cows. Analysis of milk production during lactation showed high milk yield during the first lactation (7315-7688 kg) in the imported animals at this farm. A slight decrease in yields by 3.4-5.1% (to 6939-7426 kg) was observed to the third lactation This downward trend in milk yield of cows with age does not match the physiological capabilities of animals. No significant difference (P ˃ 0.05) in fat content of milk also was found with its tendency to increase by 0.08-0.22% with age. For the third lactation fat content in milk was 0.13% (P ˃ 0.05) higher for the cows imported from Denmark. Predominance in protein content of milk (P ˃ 0.05) was in the imported cows from Hungary on average values within 3.34-3.42%. This figure declined with age from 3.3% to 3.1% in the cows from Denmark. Significant differences were not revealed in comparing milk productivity of cows imported from Denmark with performance of their contemporaries of native origin. Difference in milk yield did not exceed 6.6%, fat yield – 5.8% and protein yield – 6.8% (P ˃ 0.05). The fat and protein content in the milk of cows in the compared groups was at the same level within 3.1-3.3%. Similar comparison of Holstein cows imported from Hungary and their contemporaries of native origin had slightly different results. The predominance in milk yield during the first lactation was noted for the local cows by 4%, fat content in milk – by 0.04% and protein content – by 0.1%, fat yield – by 5.4% and protein yield – by 7.1 %. Milk yield during the third lactation was significantly higher for imported livestock by 13.5% (1000 kg), fat content – by 0.04% and protein content – by 0.08%, fat yield – by 15%, protein yield – by10% at P ˃ 0,05. The research of duration and efficiency of economic use found slightly higher levels of lifetime measures of the imported cows from Denmark (R ˃ 0.05). In the calculation of milk yield per a day of life, economic use and lactation slight advantage (P ˃ 0.05) also was noted for the imported cows (by 0.6, 2.2 and 1.9 kg). The numbers of lactations and calves obtained from the cows were within 2.4-2.7 and 3.4-3.5 respectively. A similar slight predominance (P ˃ 0,05) of the animals imported from Denmark was for coefficients of economic use (by 6.5%), lactation (by 1.8%) and productive use (3.5%). A slightly different situation was observed in comparing the lifetime measures of the cows imported from Hungary with their contemporaries. In these groups of animals, small and insignificant predominance was in all the studied traits (P ˃ 0.05) recorded for local contemporaries. Lifetime milk yield was 2.641 kg lower, so fat yield was 73 kg less and protein yield – 64 kg less. Lifetime fat and protein content in milk was within 3.69-3.70% and 3.35-3.36% on average, respectively. Milk yield per a day of life, economic use and lactation in the both groups was almost at the same level (9.1-9.7, 16.2-16.7 and 20.2-20.6 kg respectively). On average in the both groups during lifetime of cows 3.5-3.8 calves were received and number of lactations was within 2.9-3.2. Coefficients of economic use, lactation and productive use were 0.5, 2.4 and 6.0% lower respectively in the cattle imported from Hungary as compared to the local contemporaries. Coefficient of variability of lifetime measures averages for the imported cows was to 66.6%. Coefficient of variability of average fat and protein content in milk during lifetime (1.9-2.9%) indicated high consolidation of the traits. High variability of lifetime measures confirms significant opportunities for selection of cows on these traits. Consequently, Holstein cattle imported from Hungary and Denmark showed satisfactory adaptive ability under condition of "Agrosvit" breeding farm that provided high milk yield (7315-7688 kg) during the first lactation with small (by 3.4-5.1%) reduction in yields during the third (to 6939-7426 kg). Fat content in milk was 3.64-3.86% and increased by 0.08-0.22% with age. The protein content in milk fluctuated within 3.30-3.42%. There was no difference in comparing milk productivity of imported Holstein cows and their local contemporaries. The difference in all cases is insignificant. The revealed tendency of higher productive performance is in favour of livestock imported from Denmark. The same traits in cattle from Hungary were slightly lower. Average lifetime measures at the imported animals from Denmark were slightly higher and insignificant (P ˃ 0.05) compared to local contemporaries. And the same averages at the cattle imported from Hungary were slightly lower and insignificant. High coefficients of variability of the studied traits were found that would allow intensive selection of cows and to create herds with high productivity and long-term economic use.

The Impact

The research was performed on Holstein-Friesian and Black and White bull dams reared on five farms of Agricultural Corporation of Belgrade - PKB. The study included 575 lactations of cows selected as bull dams and their progeny calved in the period from 2007 - 2014 and represent progeny of 24 bulls. The following dairy traits were analysed in a standard lactation (305 days): milk yield (kg) - MY, milk fat content (%) - % MF, milk fat yield (kg) - MFY, protein content (%) - % PC and protein yield (kg) - PY. Holstein-Friesian bull dams and their progeny, in standard lactation, produced on average 9239.84 ? 1607.64 kg of milk, with a milk fat content of 3.44 ? 0.20 and protein content of 3.21 ? 0.12. The impact of bull - sire, year of birth, lactation order, farm, year and calving season was present at different levels of statistical significance on yield traits, while the genetic group had no influence on any of the milk traits. Bull - sire, year of birth, lactation order and calving season did not influence the variability of milk fat and protein content. Heritability of observed milk traits was medium to low. The content of milk fat and protein had the lowest values of heritability, 0.014, and 0.024, respectively. The heritability of milk yield, milk fat yield and protein yield was 0.293, 0.319 and 0.273, respectively.

Sucrose overfeeding increases intrahepatocellular (IHCL) and intramyocellular (IMCL) lipid concentrations in healthy subjects. We hypothesized that these effects would be modulated by diet protein/fat content. Twelve healthy men and women were studied on two occasions in a randomized, cross-over trial. On each occasion, they received a 3-day 12% protein weight maintenance diet (WM) followed by a 6-day hypercaloric high sucrose diet (150% energy requirements). On one occasion the hypercaloric diet contained 5% protein and 25% fat (low protein-high fat, LP-HF), on the other occasion it contained 20% protein and 10% fat (high protein-low fat, HP-LF). IHCL and IMCL concentrations (magnetic resonance spectroscopy) and energy expenditure (indirect calorimetry) were measured after WM, and again after HP-LF/LP-HF. IHCL increased from 25.0 ± 3.6 after WM to 147.1 ± 26.9 mmol/kg wet weight (ww) after LP-HF and from 30.3 ± 7.7 to 57.8 ± 14.8 after HP-LF (two-way ANOVA with interaction: p < 0.001 overfeeding x protein/fat content). IMCL increased from 7.1 ± 0.6 to 8.8 ± 0.7 mmol/kg ww after LP-HF and from 6.2 ± 0.6 to 6.9 ± 0.6 after HP-LF, (p < 0.002). These results indicate that liver and muscle fat deposition is enhanced when sucrose overfeeding is associated with a low protein, high fat diet compared to a high protein, low fat diet.

A field experiment was carried out at Agronomy Farm of Patuakhali Science and Technology University, Dumki, Patuakhali, from December 2011 to March 2012, to study the effects of nutrient foliar spray on soybean growth, yield and protein content. Soybean variety Shohag was used as the test crop. N, NPK, NPKS and NPKMg were sprayed and applied in the soil at vegetative and pod filling stages. Soil fertilizations were done as recommended dose, and no soil and foliar fertilization were considered as control. Plants were sprayed at the rate of 100 mg/L of water corresponding to each nutrient. The experimental design was a split plot with three replications. Result indicated that nutrient foliar spray, either singly or in combination, enhanced the growth and yield of the soybean as well as protein content in soybean seed, at the two growth stages compared to soil fertilization. However, spraying nutrients during pod filling stage was better than vegetative spraying stage in all characters studied. The highest amount of protein content in soybean seed and grain yield were obtained by spraying NPKMg.Bangladesh Agron. J. 2014, 17(1): 67-72

Abstract Background:Objective of the study was to investigate the response of groundnut genotypes to combined application of phosphorus and zinc on yield and nutritional contents. A field experiment was conducted at Sheka-Tekli in 2017/18 cropping season. Methods:The treatments were consisted of three groundnut genotypes (ICGV00308, ICGV91114 and Sedi) as main plot and four combined PZn fertilizer levels (00), 10 kg P/ha +0.50 g Zn/L, 20 kg P/ha +1 g Zn/L and 30 kg P/ha+1.5 g Zn/L as sub plot were assigned in split plot design with tree replications.Result: The result indicated that yield and yield components respond significantly to the main and interaction effects. The highest significant seed yield (2,529 kg/ha) and protein content (37.79%) were obtained in response to the application of P30Zn1.5 fertilizer on sedi variety in the loamy sand soil The percentage of crude protein and fat content had significantly affected by interaction components. Most of the yield component traits showed strong positive correlation with seed yield. While the lowest seed yield was recorded from ICGV00308 without fertilizer. The highest fat content (43.95%) was gained from genotype ICGV00308 at P30Zn1.5 fertilizer. From the interaction of sedi with P30Zn1.5 fertilizer was recorded highest protein content. Based on economic analysis the highest MRR (380.58%) was obtained from ICGV00308 genotype at P10Zn0.5 fertilizer. Conclusion: From the result of the study, application of PZn fertilizer increases seed yield of groundnut. Therefore, based on the MRR result ICGV00308 genotype at P10Zn0.5 fertilizer was optimum for groundnut production in the study area and similar agro-ecologies.

Goats are livestock that is mostly raised by small farmers in Indonesia because they are easier to raise. Apart from having the potential to become meat, several breeds of which are kept as milk-purpose. Milk traits of each breed differ from one another. Therefore, this study tried to observe genetic differences of 25 goat breeds with statistical approach. Information about milk traits from 25 goat breeds is obtained from published journal. Multidimensional preference analysis and average linkage cluster analysis were performed using SAS 9.4 to determine the differences in goat breeds from three traits, namely milk yield, fat content, and protein content. Multidimensional preference analysis was able to see the advantages of breeds from the three observed traits. Goat breeds with superior milk yields are Saanen, Camosciata delle Alpi, and Charmoisée. Sarda Primitiva, Sarda, Etawah Grade have high fat content in milk. In addition, Arsi-Bale and Somali have high protein content. Average linkage cluster analysis is able to observe the genetic relationship of goat breeds based on three traits. According to average linkage cluster analysis, we found four clusters for goat breeds in this study. With existing statistical approaches, we can evaluate genetic diversity in milk traits.

Abomasal infusion of casein has been shown to increase the milk yield, fat yield, protein content and protein yield while no clear-cut effects were observed with infusion of glucose (Ørskov, Grubb and Kay, 1977 and confirmed by Oldham, Bines and MacRae, 1983). Little information is available about the changes in blood parameters with abomasal infusion of glucose or casein. The objective of the present experiments was to relate changes in milk production to blood parameters in dairy cows given casein or glucose as an infusion into the abomasum during early or late lactation.

Abstract:Background:Currently, there is a growing interest in lacto-engineering in the neonatal intensive care unit, using infrared milk analyzers to rapidly measure the macronutrient content in breast milk before processing and feeding it to preterm infants. However, there is an overlap in the spectral information of different macronutrients, so they can potentially impact the robustness of the measurement. In this study, we investigate whether the measurement of protein is dependent on the levels of fat present while using an infrared milk analyzer.Methods:Breast milk samples (n=25) were measured for fat and protein content before and after being completely defatted by centrifugation, using chemical reference methods and near-infrared milk analyzer (Unity SpectraStar) with two different calibration algorithms provided by the manufacturer (released 2009 and 2015).Results:While the protein content remained unchanged, as measured by elemental analysis, measurements by infrared milk analyzer show a difference in protein measurements dependent on fat content; high fat content can lead to falsely high protein content. This difference is less pronounced when measured using the more recent calibration algorithm.Conclusions:Milk analyzer users must be cautious of their devices’ measurements, especially if they are changing the matrix of breast milk using more advanced lacto-engineering.
