The Stability

Excess summer milk and a lack of product diversity are major problems facing Taiwan’s dairy goat industry. Gouda and Mozzarella cheeses made with cow milk are popular products for leisure farms in Taiwan, and they produce a large amount of cheese whey as waste. Our objective is to identify the unstable phenomena of pH-adjusted goat milk through the use of Turbiscan Lab® Expert and to produce ricotta cheeses using cow cheese whey waste and excess goat milk. Delta backscattering (∆BS) profiles and the Turbiscan stability index (TSI) were used to evaluate the stability characteristics of goat milk adjusted to pH 6.7–5.2. The results show coagulation phenomena in skimmed goat milk and sedimentation phenomena in full-fat goat milk, when the pH was adjusted to 5.2. The TSI values of goat milk at pH 5.7 and 5.2 were significantly higher (p < 0.05) than that of a control. Therefore, 80/20 cow cheese whey/skimmed goat milk and 80/20 cow cheese whey/full-fat goat milk mixtures were acidified to pH 5.5 and heated at 90 °C for 30 min to produce ricotta cheeses A and B. The hardness value, moisture, protein, and ash contents of ricotta cheese A were significantly higher (p < 0.05) than that of ricotta cheese B, but no significant difference was found in terms of sensory evaluation.

A new type of cow’s milk, called A2 milk, has appeared in the dairy aisles of supermarkets in recent years. Cows’ milk generally contains two major types of beta-casein as A1 and A2 types, although there are 13 genetic variants of β-casein: A1, A2, A3, A4, B, C, D, E, F, H1, H2, I and G. Studies have shown that A1 β-casein may be harmful, and A2 β-casein is a safer choice for human health especially in infant nutrition and health. The A2 cow milk is reportedly easier to digest and better absorb than A1 or other types of milk. The structure of A2 cow’s milk protein is more comparable to human breast milk, as well as milk from goats, sheep and buffalo. Digestion of A1 type milk produces a peptide called β-casomorphin-7 (BCM-7), which is implicated with adverse gastrointestinal effects on milk consumption. In addition, bovine milk contains predominantly αs1-casein and low levels or even absent in αs2-casein, whereby caprine milk has been recommended as an ideal substitute for patients suffering from allergies against cow milk protein or other food sources. Since goat milk contains relatively low levels of αs1-casein or negligible its content, and αs2-casein levels are high in the milk of most dairy goat breeds, it is logical to assume that children with a high milk sensitivity to αs1-casein should tolerate goat milk well. Cow milk protein allergy (CMPA) is considered a common milk digestive and metabolic disorder or allergic disease with various levels of prevalence from 2.5% in children during the first 3 years of life to 12–30% in infants less than 3 months old, and it can go up to even as high as 20% in some countries. CMPA is an IgE-mediated allergy where the body starts to produce IgE antibodies against certain protein (allergens) such as A1 milk and αs1-casein in bovine milk. Studies have shown that ingestion of β-casein A1 milk can cause ischemic heart disease, type-1 diabetes, arteriosclerosis, sudden infant death syndrome, autism, schizophrenia, etc. The knowledge of bovine A2 milk and caprine αs2-casein has been utilized to rescue CMPA patients and other potential disease problems. This knowledge has been genetically applied to milk production in cows or goats or even whole herds of the two species. This practice has happened in California and Ohio, as well as in New Zealand, where this A2 cow milk has been now advanced commercially. In the USA, there have been even promotions of bulls, whose daughters have been tested homozygous for the A2 β-casein protein.

This paper compared the chemical (Proximate and mineral), acidity, microbial count and organoleptic properties of yoghurt samples produced from Nigeria locally bred goat and cow milk with commercially retail yoghurt during 14days of refrigerated storage. Yoghurt production was conducted by inoculation of the milk samples at 43oC for 6hrs with 2% of streptococcus thermophillus and lactobacillus bulgarus active culture. The total ash content of yoghurt ranges from 0.23g/100g in the commercial yoghurt sample to 0.84g/100g in yoghurt from goat  milk which is considered significantly higher than that observed for yoghurt from cow milk. The commercially retail yoghurt had a significantly higher (P < 0.05) total solid matter than yoghurt from goat and cow milk. Calcium and phosphorus contents were significantly (P < 0.05) lowest in the commercial yoghurt (0.28%) to a significant higher value of 0.28% in goat milk. A statisitically significant drop in pH values was observed in the commercial yoghurt sample after one and two week storage compared to yoghurt from goat and cow milk. High lactic acid bacteria were observed in yoghurt from cow milk with lactococci group being higher than the lactobacilli group throughout the storage period. The yeast count range from a significant low (P < 05) value of 2.22 cfu/ml-1 in commercial yoghurt sample to 3.22 and 3.24 in goat and cow milk respectively on day zero of storage. By the 7days of storage, the commercially retail yoghurt was significant (P < 0.05) least desirable with respect to colour, taste and overall acceptability while there was no significant difference in the consistency of all the yoghurt samples.

This paper aimed to evaluate the changes in the thermal stability of goat milk, cow milk and homogenized milk under different pH conditions. The results showed that goat milk was of type B milk, and the thermal stability were positively correlated with the pH value. But cow milk was of type A milk, the most stable pH of fresh milk was 6.9, while it was 6.7 for homogenized cow milk. Compared with cow milk, the acidification of goat milk was stronger due to heat. Therefore, in the process of milk production, the germicidal heating conditions of two different milk sources should be determined according to their thermal stability.

This study was conducted to assess the sensory characteristics and acceptability of goat milk in Odeda Local Government Area of Ogun State. A total of seventy respondents were selected randomly. Milk collected from lactating West African Dwarf goats was pasteurized at a o temperature of 74 C for five minutes, cooled, packaged in small polythene and sealed withmachine and refrigerated. The milk was taken to various settlements in Odeda Local Government of Ogun state for sensory evaluation. Majority of the respondents were students 54.3% only a few 12.9% were traders with a high percentage between the ages of 21-30. Also, 67.1% and 70.0% of the respondents were Christian and Yorubas, respectively. Moreover, 65.7% of respondents were married, while 34.3% were unmarried. The married had a family size of ≤ 2. Majority of the respondents (88.8%) had tertiary education. The small number of respondents 37.1% involved in ruminant production had only 2 years ruminant farming experience and kept fewer than 5 goats. About 60 % of the respondent consumed milk on weekly basis while 6% consumed milk on daily. It was observed that 100% of the respondents preferred cow milk despite the fact that 78.6% of the respondents were aware of goat milk consumption. The taste, colour, odour and flavor of goat milk were rated as Very good by 55.7%, 37.1%, 41.4% and 41.4% of respondents respectively. Majority of the respondents had a favourable disposition towards the taste (75.5%), colour (62.9%), odour (80.0%) and flavour (61.4%) when compared with other milk products in the market. Thus, goat milkt could be taken as alternative to cow milk without any detrimental effect It then become imperative for this positive perception to be explored by the government and other relevant development agencies so as to increase food supply to alleviate protein deficiency and thereby improved the economy.

The Stability

Proper posture provides the best balance and body stability at minimal muscular effort. It is constantly controlled by the central nervous system, which integrates the stimuli from the proprioceptors (deep feeling sensors), vision receptors, and balance receptors through the subcortical structures. The main purpose of the study was to describe single stance stability and its correlation with the degree of scoliosis and trunk rotation among patients suffering from idiopathic scoliosis and in the control group without scoliosis. The study included 80 patients (69 girls and 11 boys) and 40 healthy children without scoliosis (21 girls and 19 boys). The Cobb angle technique was used to determine the magnitude of the deformity. All subjects were divided into three subgroups according to Bogdanov’s classification. Single stance stability with eyes open and eyes closed was assessed with an electronic postural station—Delos Postural Proprioceptive System (DPPS). In case of multiple group comparisons for variables with normal distribution ANOVA with Scheffe, post hoc test was used or Kruskal-Wallis test was used as the nonparametric equivalent. The relationship between the two continuous variables was investigated using either Pearson product-moment correlation or Spearman’s rank correlation. In all these calculations, the statistical significance level was set to p<0.05. The single stance test showed a significant difference between the stability index with eyes open and stability index with eyes closed in study and control groups. The character of these alterations is influenced by the degree of trunk rotation. The degree of scoliosis according to Bogdanov classification does not determine the decrease in stability indexes. In summary, significantly lower values of the stability index during one-leg standing with eyes closed indicated balance impairment, which is mainly connected with inadequate functioning of the proprioceptive system.

Sustainable Food Production

Goats contribute significantly to human nutrition, food security and income of resource-poor small farmers in Asia, Africa and beyond. Because of the high content of mono- and polyunsaturated fatty acids in goat milk, it is beneficial for human health resulting in it being sold at premium prices of three to nine times the price of cow milk in countries like China, Malaysia, Indonesia and Thailand. Goats play a significant role in farming systems that directly impact on the capacity of rural farmers striving for the objective of sustainable food production systems. Increasing sustainable food production, particularly of animal proteins, presents major challenges to these small farms in the face of massive demands that are driven by rapid growth of human populations and increased availability of disposable income. In the last two decades, expanding market demand for goat milk has resulted in the establishment of commercial dairy goat farms in several newly developed South-east Asian countries. Major challenges to expanding production exist, and include ways to utilise the well-adapted features inherent in goats and their potential production to benefit the small and commercial farmers alike. Increasing the knowledge base is a priority to stimulate improved production systems and, increased the income of dairy goat farmers and other people involved in the industry. The recent establishment of the Asian-Australasian Dairy Goat Network supported jointly by FAO and Universiti Putra Malaysia, and national programs of participating countries, are committed to address these objectives and facilitate much-needed improvements to sustain dairy goat production systems in Asia and beyond.

Kefir is one of the fermented beverages which has a distinctive taste from other fermented milk products. Based on the results of several studies concluded that one that affects the quality of kefir is the milk of being used for. The purpose of this study was to examine the comparison of physiochemical quality of kefir made from goat’s milk and cow’s milk. This study used Completely Randomized Design (CRD) with two treatments and five replications using different milk which was goat’s milk and cow’s milk. Parameters measured were the weight gain of kefir grain (PBBK), ethanol content, the percentage of lactic acid and pH of kefir. The data obtained were analyzed by using the Analysis of Variance and if the treatment was significantly different, then the test continued with the Least Significant Difference (LSD). The results showed that kefir produced with different types of milk showed a significant effect (P <0.05) on pH parameters, lactic acid percentage, and ethanol content, but no significant effect (P>0.05) on the value of PBBK. It can be concluded that the best kefir made of goat milk has characteristics: pH value 3.89, the percentage of lactic acid 0.14; PBBK 26.61%; and 0.72% ethanol content.

We investigated differences between goat and cow milk by exploring the factors influencing milk stability by testing the heat coagulation time. Heat-stable milk samples were characterized by a higher pH, a lower heating temperature, a lower calcium concentration, a higher concentrations of EDTA-2Na, phosphate and citrate. However the sucrose concentration caused different patterns of heat stability. The heat stability of milk increased as the sucrose concentration increased from 10% to 30%, then decreased as it rose above 30%. Compared with cow milk, goat milk is less stable to heat treatments being affected by pH, heating temperature, and the addition of calcium chloride, disodium EDTA, disodium hydrogen phosphate, and sucrose. After adding sodium citrate, the heat stability of goat milk was better than that of cow milk, with ANOVA results indicating a statistically significant difference.
