SUMMARY The objective of this study was to evaluate the performance of male colonial chickens fed diet supplemented with commercial probiotic (Calsporin ®). A total of 210 male chicks Label Rouge lineage were used and they were raised in experimental shed up to 30 days old. These birds had free access to the pickets of Tifton-85, from 31-90 days of age. The experimental design was completely randomized, two treatments, one containing feed supplemented with probiotic Bacillus subtillis (300 g t-1 Bacillus subtillis 1×109 UFCg-1) and another one without it, with ten replications per treatment, consisting of 21 chickens/replication. The mean of body weight (BW), weight gain (WG), feed intake (FI), feed conversion (FC), mortality and viability were evaluated. The data were submitted to variance analysis and the averages of the treatments were compared by the F-test at 5% of significance. The addition of probiotic (300 g t-1 Bacillus subtillis 1×109 UFCg-1) in the diet of Label Rouge broilers did not interfere in the MW, WG, and FC variables in the total period from 1 to 90 days (P>0.05); the MFI variable differed (P <0.05), with higher consumption in chickens receiving the diet with the probiotic. The inclusion of probiotic in the wild-type chicken ration did not improve the productive performance of poultries possibly due to a low challenge by pathogenic microorganisms in the environments in which they were raised.

The objective of this study is to evaluate the effects of in-egg inoculation with sources of conjugated linoleic acid (CLA) and lauric acid (AL), going by the weight of lymphoid organs and the biochemical profile of the blood of cut quails, from one to 35 days of age. We used 360 quails distributed in a completely randomized design, in six treatments and six replicates of 10 birds per plot. Corn oil (OM) was used to dilute the CLA and AL. The experimental treatments were: healthy eggs (control); eggs inoculated with OM thinner; eggs inoculated with CLA 120 mg / 50 mL OM; eggs inoculated with CLA 240 mg / 50 mL OM; eggs inoculated with AL 60 mg / 50 mL OM and eggs inoculated with AL 90 mg / 50 mL OM. The results were analyzed through Program R at the level of 5% significance. To verify the normal distribution of errors, the Shapiro-Wilk normality test was applied. At 21 days, an effect of p < 0.05 was observed for the total blood cholesterol content, inoculations with CLA reduced, even as AL increased, regardless of the level. At 35 days, it was found (p < 0.05) that the levels of total cholesterol and AST in the blood decreased with inoculations of CLA and AL at the lower levels, compared to those that did not receive the inoculations. The CLA and AL levels supplemented via egg inoculations did not interfere with the weight of the lymphoid organs (thymus, Fabricius bursa) of the birds, at both ages. Supplementation in eggs of cut quails with CLA 240 mg reduced the total blood cholesterol content compared to CLA 120 mg, at 21 days of age. At 35 days of age, higher concentrations of CLA and AL increased the total cholesterol and AST in the blood of birds and AL had a greater effect on the increase than CLA.

Among family farmers, milk production is one of the main activities developed. The aim of this work was to evaluate the milk quality in the some properties and to monitor or manage the properties for observation of deficient points. The project was conducted on rural properties in the Bambuí / MG city and which works with bovine milk production, saves between 50 and 600 liters per day. The work started on March 2015 and ended on February 2016 and was developed through a partnership with Laticínio Total União Ltda. Three steps were performed, namely: data collection, milk quality analysis and work results obtained through meetings and lectures with producers and publication of booklet. The project's target farms was 12 rural properties with an average production of up to 600 liters of milk per day, without qualifying as small and medium producers, selected after the first phase. The milk quality analyzes were performed without 30 days interval for 4 months and the monitoring of the productive management performed throughout the project. It can be seen that the producers analyzed largely did not have the herd specialized in milk production and did not receive professional technical assistance.

The objective of this study was to evaluate the effects of inoculation in egg with sources of conjugated linoleic acid (CLA) and lauric acid (LA) on hatchability, zootechnical performance and carcass characteristics of quails from one to 35 days of age. On the 7 th day of incubation, the eggs were inoculated with 0.05 mL of the supplement according to the treatments, CLA and LA. After birth, the birds were housed in cages until 35 days. A completely randomized design was used, with six treatments and six replicates of 10 birds per cage. The inoculations in eggs with CLA and LA did not interfere in the performance and carcass characteristics of quails at 21 and 35 days of age. However, may be associated with a decrease in egg hatchability. The highest absolute weight of the gizzard was observed at 35 days, from birds inoculated in egg with CLA 240 mg and LA 60 mg in the incubation phase, in comparison to the other treatments. In conclusion, the reduction in hatchability makes it impossible to recommend the use of conjugated linoleic acid and lauric acid -in ovo.

The goat's milk is an excellent choice to replace cow’s milk for children and adults, who are allergic to cow’s milk. Both the proteins and the fat portion of goat’s milk are absorbed by the body faster than cow's milk. Visually it is not possible to differentiate cow’s milk from goat’s milk, which can be differentiated through odor and taste which generates some concern to consumers. The objective of this study were to evaluate the acceptability of goat’s milk, compared to cow’s milk by children and young adults between 06 and 21 years old, in public network of schools Bambuí–MG, living in different socioeconomic levels, in order to verify if there is difference, in acceptance, between these two types of milk and study if the age and socioeconomic status could influence the results. Samples were prepared with chocolate powder and subjected to sensory evaluation by a group of 330 students, who are milk consumers. The samples were evaluated for preference through the hedonic scale of 5 points, asking about the score of the consumers and the preference of each type of milk. The test was conducted in two public schools.  the data were submitted to ANOVA and Tukey test for comparison of means. Although goat's milk has some compositional characteristics and different physicochemical properties of cow's milk, there was no difference between them, due to acceptability between students of the public high school and elementary school network. The mixture 50% goat milk + 50% cow's milk generated greater rejection of the sampled population, a fact justified by the formation of small clots when mixing the different types of milks. Conventional cow's milk can be replaced by goat's milk in school meals, regardless of the age group and socioeconomic status of students.

Objetivo. Evaluar el leucograma de codornices de engorde inoculadas in ovo del ácido linoleico conjugado (CLA) y ácido laurico (AL) mientras están expuestas a un desafío sanitario. Material y métodos. El agua de bebida fue ofrecida siente días antes de la llegada de las codornices y solo fue reabastecida, no se realizó lavado de bebederos, durante toda la fase del experimento. Los tratamientos fueron distribuidos en 480 huevos fértiles, en el 7° día de incubación: Control negativo: sin perforación, control positivo: inyectado con diluyente (aceite de maíz; AM; CLA 120: 120 mg CLA/AM; CLA240: 240 mg CLA /AM; AL 60: 60 mg AL /AM y AL90: 90 mg AL /AM. Fue utilizado delineamiento completamente al azar con cuatro repeticiones. Los leucocitos totales y el conteo diferencia de leucocitos fueron evaluados a los 21 y 36 días de edad. Resultados. Las inoculaciones, no presentaron efecto significativo (p>0.05) en los parámetros evaluados. Se observó una media de 10927.1 ± 2933.6 células/μl, 61.6 ± 7.31%, 32.0 ± 7.13% e 0.57 ± 0.21 para conteo total de leucocitos, linfocitos, heterofilos y la relación heterófilos/linfocitos, respectivamente, a los 21 días. A los 36 días, observamos una media general de 13291.7 ± 3559.0 células/μl, 65.0 ± 9.29%, 29.3±9.93% y 0.50 ± 0.24, para esas mismas variables, respectivamente. Conclusiones. Los niveles de inoculación in ovo de CLA e AL no afectaron el leucograma de codornices de engorde criadas en desafío sanitario.
