Factors Affecting Machinations at Dairy Farms : An Appraisal from Economic Perspective

This study was undertaken to get a comprehensive idea about the favourable and unfavourable factors for adoption of dairy automation/ machinations as perceived by dairy farmers, and study the economic impact of semi-automatic milking machine for small, medium and large dairy unit using the analysis of total cost and monetary benefits. The study was carried out in north Indian states, 30 commercial dairy farmers were selected constituting a total of 150 respondents practicing commercial dairy farming under survey method of investigation. Results revealed that time saving in dairy farm operations, drudgery reduction, and maintenance of hygiene and quality of milk and milk products were perceived as top three favourable factors for adoption of dairy automation or machination. The high initial investment required for dairy automation, no extra milk price for hygiene and quality products through the adoption of dairy automation in the market, and high cost of equipment and less subsidy provided by the government were perceived as top three favourable factors for adoption of dairy automation or machination. The study indicated that adoption score of the respondents were not significantly correlated with age. It implies that age, education, family size land holding and experiences of dairy farming does not affect the adoption of dairy automation technologies. The additional monetary benefits apart from this economic benefit’s other benefits such as clean and hygiene milk, health care and management in economic terms were calculated about 43800, 39,600, and 64,000 per year for small, medium, and large dairy unit, respectively

The Effect of Mocaf Substitution on Crispness and Organoleptic Quality of Milk Sticks

Milk sticks are one of the dairy products that are served in the form of snacks. One of the ingredients added in making milk sticks is wheat flour which has a high amylose content. It causes the resulting milk sticks to be less crunchy. It is necessary to substitute flour with low amylose content, namely mocaf (Modified Cassava Flour). This research objective was to determine the effect of mocaf on the level of crispness and organoleptic quality of milk sticks. Milk sticks was made in animal science laboratory UNISKA Kediri by adding different percentage of flour: P0 (100% wheat flour), P1 (90% wheat flour and 10% mocaf), P2 (80% wheat flour and 20% mocaf), P3 (70% wheat flour and 30% mocaf), and P4 (60% wheat flour and 40% mocaf) in six replications. This research using completely randomized design (CRD). These results indicated that the substitution of mocaf in the manufacture of milk sticks could reduce the moisture content of the milk sticks so that the substitution of mocaf could increase the crispness. The organoleptic assessment was carried out on the parameters of color, taste, and crispness. There were no significant differences between the color and taste parameters, while the crispness showed that P0 was not significantly different from P1, but it was significantly different from P2, P3, and P4.

Sensitivity analysis of environmental impact of milk powder spray drying system based on intelligent algorithm

The increasing market demand for milk powder has not only promoted the production capacity of milk powder, but also increased the impact on the environment. Therefore, it is very important to study the relationship between the environmental impact of milk powder spray drying (MPSD) system and system-related parameters and identify the key parameters to improve the efficiency of the sustainable improvement of the system. Treed Gaussian Process (TGP) and Standardized Regression Coefficients (SRC)methods are used to analyze the sensitivity of the system to environmental impacts. The results show that the inlet air temperature of the drying tower has the greatest impact on the environment of the system, accounting for about 82%, followed by the atomization pressure and the feed pump speed, accounting for about 9% and 8% respectively. Moreover, not only the environmental performance of the system should be improved, but also the quality of milk powder should be guaranteed when optimizing the parameters such as the inlet air temperature of drying tower. This study can help the manufacturers of milk powder and related equipment to determine the priority of improving the system from the perspective of environmental protection.

Allele and genotype frequency for milk beta-casein in dairy cattle in the northern region of Tocantins State, Brazil

At present, there is a concern about the quality of milk and diseases related to its consumption, as it can generate discomfort and allergic reactions in some individuals due to its protein components. Thus, the present study was developed to identify the allele and genotype frequencies of genes for β casein, A1 and A2, in dairy herds in the region of Araguaína-TO, Brazil. Genetic material from 421 animals (crossbred dairy cattle in lactation) was used. All animals were numbered for identification, and DNA samples were extracted from hair bulbs. Samples for two markers from the polymorphic regions were characterized and confirmed by real time PCR using the ABI Prism® 7500 Sequence Detection System (Applied Biosystems). Allele and genotype frequencies were determined using the TaqMan™ detection system, where the primer and probe release different fluorescence signals for each allele of the polymorphism. The sampled herd showed frequencies of 28.27% for the A1 allele and 71.73% for the A2 allele. Genotype frequencies were 52.96% (223/421) for A2A2; 37.53% (158/421) for the A1A2 genotype; and 9.50% (40/421) for the A1A1 genotype. The frequency of the A1 allele for β-casein in dairy herds from the northern region of Tocantins was low and is per the results of previous studies. Although the A2A2 genotype of β-casein had a high relative frequency, the A1A2 genotype is still rather frequent, warranting greater selection pressure.

Evaluation of the Chemical Quality of Milk Powder Sold in Open Markets in Aba, Abia Atate, Nigeria

Background: Cow's milk is frequently recognized as the most nearly perfect nourishment for humans [1]. On the one hand, its tremendous nutritional value could affect human health [2]. Milk, on the other hand, is an ideal microbial culture medium [3] and is easily contaminated [1]. Milk quality and safety are commonly causes of anxiety because milk quality can be compromised during processing, shipping, storage, and marketing [4], particularly in underdeveloped nations with ineffective quality monitoring. Furthermore, uniformed traders expose milk to adverse environmental conditions due to ignorance. Objective: This study investigated some chemical parameters of milk powder sold in Aba market. Materials and Methods: A total of six (6) brands of milk powder, namely: Peak, Three Crown, Loyal, Cow Bell, Jago, and Dano milk, packaged in affordable sachets, were purchased from the new market (Abia Ohuru) in Aba town, Abia State. The samples were emptied from the sachet into sterile plastic containers, coded, sealed and transported to the laboratory immediately for analysis. Proximate, mineral, and vitamin compositions were determined using standard methods. ANOVA was used to separate the means and a significant difference was judged at p<0.05. Results: The obtained values for almost all parameters were not significantly different (p) among the samples examined. However, the obtained values were slightly lower than the values written on the labels. The obtained values and the values on the labels were not significantly different from the CODEX Alimentarius and NFDAC set standards for milk powder, except for vitamin A values for almost all the samples. Conclusion: The quality of milk powder sold in the Aba market can be considered to be good enough for human consumption, although slight quality degradation was found in protein, carbohydrates, fat, and especially in the vitamin A and B content of the samples. Exposure to harsh conditions during storage and retailing processes could be a possible reason. Recommendations: Strict and legal measures should be adopted to ensure that the quality and safety of milk in the open markets is preserved.

PENYULUHAN MASTITIS SUBKLINIS DAN KEGIATAN UJI CALIFORNIA MASTITIS TEST PADA SAPI PERAH DI KOPERASI UNIT DESA KECAMATAN NGANCAR, KABUPATEN KEDIRI, JAWA TIMUR

Subclinical mastitis is an inflammation of the udder that often attacks livestock, especially milk-producing livestock. The impact of the subclinical mastitis losses is quite large, including a drastic decrease in the quantity and quality of milk, but no pathological changes were found in cows. The Karya Bhakti Village Unit Cooperative (VUC) is a center for milk production in the Kediri Regency which accommodates dairy cows' milk products from people's farms in the Kediri Regency. The low awareness of farmers in the management of livestock health care and hygiene results in low productivity and quality of milk and the high incidence of subclinical mastitis. This encourages counseling about subclinical mastitis. The socialization method used for counseling were carried out by presenting material about subclinical mastitis with lecture techniques (power point slides), videos about the method of early detection of subclinical mastitis using California Mastitis Test (CMT), conducting demonstrations of testing milk samples using the CMT method and discussion about the material that has been delivered as an indicator of the success of counseling. This series of counseling activities is an effort to reduce the incidence of subclinical mastitis through increasing public knowledge and understanding. This activity also has a positive impact by reducing infectious diseases, especially subclinical mastitis in livestock so that the health of livestock and products from livestock will also be guaranteed both in terms of quality and quantity.Keywords: mastitis, subclinical mastitis, cows, Counseling, CMTAbstrakMastitis subklinis merupakan radang ambing yang sering menyerang hewan ternak khususnya ternak penghasil susu.

A review of the effects of different feeding regimes of cows on milk fatty acids profile and antioxidant capacity

This bibliography review analyzes the effects of different feeding regimes of cows the nutritional and sanogenic quality of milk, with a particular emphasis on milk content in functional fatty acids and non-enzymatic lipophilic antioxidants. Thus, using suitable feeding regimes of cows, fatty acid (FA) profile of milk fats can be improved by increasing the concentration in functional FA (C18:1 trans-11, vaccenic acid; C18:3 n-3, acid linolenic and C18:2 cis-9 trans-11, isomer of conjugated linoleic acid), considered as beneficial for consumer’s health. These suitable feeding regimes of cows aim using green fodder (pastures), preserving the fodder by drying or silage, supplementing the food with fats rich FA polyunsaturated (PUFA) and ensuring an optimal ratio between volume and ration concentrates. Milk yielded from grazing cows shows a considerably higher concentration of functional FA and lipophilic antioxidants (tocopherols, retinol and carotenes) and a lower content of saturated FA compared to that yielded from cows fed in shelter with TMR (total mixed ration). Also, hay-based feed rations, mainly those containing small amounts of concentrates or those supplemented with vegetable fats, ensure a milk yield with a fatty acid profile more favorable for human health and a better oxidative stability of compared to those with feed-based rations on silage or those high in concentrates.

Physico-chemical and Adulteration Profile of Dried Milk in Kashmir

Background: Milk is a highly nutritious food that serves as an excellent growth good medium for microorganisms. Converting milk into milk powder increases its shelf life and can be stored for extended period (about 1 year) without substantial loss of quality even at ambient temperatures. Methods: The current investigation was undertaken with the aim of evaluating the quality of milk powder in Kashmir division for characterizing its physico-chemical and adulteration profile. Since all the dried milk is imported in the valley, it is important to ascertain its quality. For this purpose, whole valley was divided into three zones namely north, south and central. The physiochemical properties and adulteration profile of all the milk powder samples, collected from three zones (north, center, south) were determined. Result: The physiochemical properties of all the milk powder samples were to be of approved quality, irrespective of the brand and class. Adulteration profile of milk powder was seen to match completely to the standards. Milk powder should be free from all the adulterants to ensure its safe and wholesome consumption to consumers. A very few samples were found positive to alkaline neutralizer.
