ABSTRACT The species bubalina in Argentina in 1976 was introduced in 1300 animal numbers, which were mostly aimed at the northeast region; from there the production experiment a rapid increase, reaching at present to establish an amount close to 100 mil head. In this context, the province of Formosa is one of the provinces with the highest number of animals, resulting in a productive part in the scheme and development priorities in their various skills: meat, milk, leather. In order to diversify and optimize the use of technology, the Santa Ursula incorporates special buffalo milk with a particular scheme, coordinating with the university (Holando Breeders Association) and Breeders Association Argentina Buffalo to start testing production. Estimated parameters in dairy cattle bubalino (Bubalus bubalis) in a subtropical region of the farms American (Formosa, Argentina) The soil characteristics are very different, where you can find low hills, high mountains, land with natural pastures and implemented according to the topography and soil type. What will define the landscape where the floris production. The herd consists of animals breed Murrah, Mediterranean and jafarabadi. Those who were selected from a herd of buffalo 1500. The criterion for selection is given by age, docility, phenotypic characteristics of a productive (mammary gland) and the physiological status (pregnant).The values found for milk production averaged 1.907 ± 0492 and 7.463 results and 3.616 ± 1.415 ± 0.675 of fat and protein respectively. This indicates that the individual production demand greater investment in technology such as genetics, nutrition, technology and milking facilities. The behavior of solids is a correlation between levels of milk production and its corresponding value of fat and protein. Expressed high levels of milk production with low percentages of fat and protein.

Abstract The main objective of present investigation was to study the effect of lactation stage and animal’s breed on physicochemical properties of milk from buffalo. The experiment was carried out from May to September, 2008, in the Três Irmãos farm, located in the Maiquinique (Bahia, Brazil).The follow physicochemical parameters were determined: total acidity and pH, density, cryoscopy, which indicated that there was not interaction between breed and lactation stage.

INTRODUCTION The importance of food science and technology for improving the human beings quality of life is highlighted by the rising search for healthy food, with high nutritional value, available and accessible to people. With this, the investigation of alternative food sources has been the subject of extensive researches in the last decades. Buffalo’s milk is promising in this context, since it has a superior nutritional value due to the high levels of fat, protein and minerals (specially calcium and phosphorus), that can be consumed in natura and may be used as raw material for producing diary products, varying in accordance to each regional culture1, 2 savu. Moreover, buffalos are extremely rustic and demonstrate a high adaptation capacity, being able to survive in diverse environments with huge weather variations, relief and vegetation, so growing them is very economically feasible4-3,5-4. The data found regarding buffalo’s milk characteristics are very varied, since several factors influence the physicochemical properties6, 5-8, 6. In this context, the aim of this work was to evaluate the quality of milk from buffalo herd raised in the Bahia southwest, concerning physicochemical characteristics, as well as factors that influence, such as the lactation stage and the animal’s breed.

MATERIALS AND METHODS The experiment was carried out from May to September, 2008, in the Três Irmãos farm, located in the Maiquinique (Bahia, Brazil). Twenty four animals were separated, according to extern characteristics, 12 were of the Murrah breed and 12 of the Jafarabadi breed. Animal’s food was pasture with Brachiaria Decumbens, with mineral salt supplement available. Buffalos of the same race were subdivided in three groups, four animals each. One liter of milk was sampled from every animal. Samples from animals of the same group were mixed, forming a composed sample. Thus, the composed samples were collected during the lactation, at the beginning (approximately one month after lactation), in the middle (fifth month of lactation) and at the end (near the ninth month of lactation).The follow physicochemical parameters were determined: total acidity and pH, density and cryoscopy. For statistical analysis, the results obtained were treated using 538

the totally random experimental outline with a 2 x 3 factorial design, two races (Murrah and Jafarabadi) and three lactation phases (beginning, middle and end), with three replicas for each experiment. To study the effect of race, lactation phase and the interaction between race and lactation phase, the results obtained were treated in SAEG, according to statistical methods, using the variance analysis and comparison tests among averages (Tukey), with 5% probability.

RESULTS AND DISCUSSION According to the results obtained for the physicochemical characterization of buffalo’s milk (Table 1), it was found that there was no interference statistic at 5% probability of breed and lactation stage studied in relation to pH, acidity, cryoscopy point and density.

Table1. Physicochemical properties of Murrah and Jafarabadi Buffaloes milk

Average followed by the same letter, lower case on the line to breed and capital letter in the column for lactation stage, don’t differ (P>0.05) by F and Tukey tests. There was no difference (p> 0.05) in acidity and pH during the three stages of lactation, however, noted that these parameters varied between Murrah and Jafarabadi breed. Jafarabadi breed showed higher pH (6.93) and lowest Dornic values (13.8 °D) when compared with the results of the Murrah which presented pH 6.79 and acidity of 16.3 °D. Regarding the cryoscopy point determined in Hortvet degrees, we identified a significant difference (p 0.05) between the results of the milk samples of buffaloes in early (-0.535 °H), mid (- 0.539 °H) and late (-0.542 ° H) lactations. The density, it is related to fat and solids not fat. There was no significant difference (p> 0.05) between breeds and between lactations stage. The results obtained may contribute for establishing quality control standards of buffalo’s milk produced in the Southwest Region of the Bahia State. Acknowledgments.
