Effect of milking time on milk production and milk quality of dairy cow fed with fermented corn cob

The aim of this study was to determine whether the addition of a homeopathic product to dairy cow feed would improve health and production efficiency, as well as composition and quality of milk. The product tested here was produced to stimulate immunity and indirectly to prevent the colonization of the mammary gland by bacteria, thereby decreasing somatic cell counts and bacteria in cow’s milk. Fifty dairy cows were used, divided into two groups: Control (n = 25) and Treated (n = 25). For 90 consecutive days, 50 grams of homeopathic product (treated group) was added to the concentrate; 50 g of the product vehicle (limestone) was added to the concentrate of the control cows. We performed composition and quality analysis on the milk (days 1, 15, 30, 45, 60, 75, and 90) as well as blood collection to carry out hematological and metabolism analyses (days 1, 30, 60, and 90). We found that fat content in the milk cows consuming the homeopathic agent was greater than that of the control group. Because of this increased fat content, there was a tendency towards higher total solids content in treated cows. A treatment effect was found in terms of total bacterial count (TBC); that is, there were lower TBCs in milk of treated animals than in control animals. There was a trend of a treatment effect versus day for somatic cell count (SCC); that is, there were lower SCC in animals that consumed the homeopathic on days 15 and 30 of the experiment. There was no difference between groups in terms of milk production; however, there was a negative correlation between milk production and TBC or SCC in the milk of cows that consumed homeopathic product. Animals in the treated group had lower total leukocyte and lymphocyte counts than did the control group, as well as a tendency toward lower neutrophil counts in these animals. Several bacteria were isolated from the cows' milk during the experimental period, with no treatment effect. In particular, we isolated Corynebacterium spp., Staphylococcus aureus, Staphylococcus epidermidis and Staphylococcus hyicus in greater numbers of cows compared to other etiologic agents. Based on these results, we conclude that consumption of the homeopathic product by dairy cows had positive effects on milk quality.

Genomic Regions

The aim of this research communication was to identify chromosome regions and genes that could be related to milk yield (MY), milk fat (%F) and protein percentage (%P) in Brazilian buffalo cows using information from genotyped and non-genotyped animals. We used the 90 K Axiom® Buffalo Genotyping array. A repeatability model was used. An iterative process was performed to calculate the weights of markers as a function of the squared effects of Single Nucleotide Polymorphism (SNP) and allele frequencies. The 10 SNPs with the largest effects for MY, %F and %P were studied and they explained 7·48, 9·94 and 6·56% of the genetic variance, respectively. These regions harbor genes with biological functions that could be related to the traits analyzed. The identification of such regions and genes will contribute to a better understanding of their influence on milk production and milk quality traits of buffaloes.

Purpose: At present, in Lankapura, there is a tremendous development in dairy sector. But milk quality issues were raised by the milk consumers and producers who collected milk from Lankapura. Although, measures have been taken to increase the milk production, the quality of milk has not been thoroughly evaluated in area. Research methodology: This study was carried out to evaluate the microbiological, compositional quality of cow’s milk collected from small scale farmers (25) and bulk milk tanks (25 samples) in the study area and to collect data about knowledge of farmers on clean milk production practices. Findings: According to the study, acidity, and average level of bacterial count of household milk production were 0.229±0.029%, 6.193±0.311 log10 CFU/ml respectively and for bulk milk production were 0.294± 0.020%, 6.6427±0.322 log10 CFU/ml respectively. The mean percentage of specific gravity, protein, fat, lactose and SNF for bulk milk samples were 1.029g/ml, 2.740%±0.0866, 4.120%±0.8065, 4.040%±0.1581, 7.6476%±0.34219 respectively and for household’s milk samples were 1.028g/ml, 2.792% ±0.1706, 4.360%±0.7314, 4.032%±0.1973, 7.5716%±0.33726 respectively. When considering management practices of farmers, only 38% farmers cleaned the milking place. Only 28% of farmers maintained proper records. The results indicated that microbiological and compositional quality (except milk fat) were not in acceptable level for both household and bulk milk samples. For microbiological quality, there was a high statistical significance of bulk milk samples than the households. Limitations: The quality of the milk was poor due to unhygienic practices and poor knowledge. Sample numbers were limited in this study, due to limited time period for this study. Larger individual coliform count could not be conducted due to limited manpower and laboratory resources. Originality/ value: As long term solutions such as farmer education programmes, incentive based milk quality systems can be recommended.

Holstein Dairy Cow

Milking is the act of removing milk from the udder on purpose to get maximum milk production. A reasonable milking interval will affect the amount of milk production. This research aims to know the extent of the milking time interval affecting Friesian Holstein dairy cow milk production and the interval of milking time that produces the best production and quality of Friesian Holstein. The research method was an experiment using a completely rand randomized with four treatments, namely: treatments 1 was 16:8 hours time delivery interval (TDI) dairy cow; treatments 2: time delivery interval (TDI) 15:9 hours; treatment 3: delivery time interval (TDI) 14:10 hours; treatment 4: time delivery interval (TDI) 13:11 hours. The observed variables are milk production and milk quality. The data were analyzed using verbal if any effect of treatment was done Duncan's distance test. Based on the results and discussion, the milking time interval significantly impacts milk production and water content. Still, it has no significant effect on the density, protein content, and milk fat content, 13:11 hours milking interval time produces the most milk and water content.

(Evaluation of milk production and quality in mastitis cows) ABSTRACT. The level of udder inflammation is one of the factors that can affect the production and quality of cow's milk. This study was aimed to determine the relationship between milk production and quality produced by mastitis cows. The material used was 30 Friesian Holstein (FH) dairy cows with a lactation period of III-V and a lactation month of 3-4. Inflammation degree of the mammary gland was determined by the California mastitis test (X1) and somatic cell count (X2) with a breed method relationship between milk production (Y1) or milk quality (fat: Y2, protein: Y3, and lactose: Y4) were determined by the multiple linear regression. The results showed that 30% of the udder quarter were healthy while 70% of the udder quarter were infected with mastitis with different levels of inflammation. There was a strong negative correlation (P 0,05; r = 0.740) between milk production, CMT and SCC score with Y1 = 16.126 - 3.064X1 - 0.001X2. Moreover, the correlation between milk production and milk quality (fat, protein, lactose) also showed a strong negative linear correlation (P 0,05) with the equation Y2 = 3.481 - 0.157X1 - 0.000X2 (r = 0.739), Y3 = 3.048 - 0.124X1 - 0.000X2 (r = 0.653) and Y4 = 4.605 - 0.106X1 - 0.001X2 (r = 0.623). In conclusion, the increased mammary inflammation level will result the decrease in milk production and milk quality.
