Produção de leite, leite residual e concentração hormonal de vacas Gir × Holandesa e Holandesa em ordenha mecanizada exclusiva

In a machine milking system in which calves were not present, oxytocin concentration (OT), cortisol release (CORT), milk yield and residual milk were evaluated for cows of three genetic groups: 1/2Gir x 1/2Holstein (n=6, genetic group F2), 1/4Gir x 3/4Holstein (n=6, genetic group F3) and Holstein (n=6, genetic group H). Group H had higher milk yield than groups F2 and F3, whereas OT was similar among groups. The increase in OT during milk-ing was greater for H and F3 than for F2. Residual milk for F2 was' higher than for F3 and H. The CORT for F2 was higher than for cows of the other two genetic groups. Cows from F2 and F3 were more stressed than H cows during machine milking, but the Gir x Holstein groups did release suffficient OT to induce an effective milk letdown response.

Constituintes sangüíneos de bovinos recém-nascidos das raças Nelore (Bos indicus) e Holandesa (Bos taurus) e de bubalinos (Bubalus bubalis) da raça Murrah

Newborn Holstein-Friesian and Nelore cattle and Murrah buffalo blood samples were collected for hemograma and serum constituents testing. Results indicated that: 1. buffalo red blood cell (RBC) counts were lower than RBC counts for cattle during the first 30 days after birth; 2. buffalo leukocytes, neutrophil and lymphocyte counts increased in older animals; 3. The highest fibrinogen levels occurred in older calves; 4. buffalo glucose levels were lower than Nelore cattle and decreased in the older calves; 5. buffalo iron, urea, and aspartate aminotransferase levels were higher than in cattle with the highest concentration at the time of birth; 6. cattle bilirubin and alanine aminotranferase levels were higher than buffalo with the highest value at the time of birth; 7. alkaline phosphatase and gammaglutamyltransferase activities were lower in the older calves; 8. buffalo magnesium levels were higher than cattle with lower concentrations at the time of birth..

Constituintes sangüíneos de vacas das raças Nelore (Bos indicus) e Holandesa (Bos taurus) e de bubalinas (Bubalus bubalis) da raça Murrah durante a gestação, no dia do parto e no puerpério

Blood constituents of Nelore, Hosltein and buffalo cows were determined during pregnancy, at the time of calving and at post-partum. It was verified that. 1. The pregnancy and post-partum periods had no influence in the erythrocyte values, but at calving the red blood cell counts and hemoglobin levels of Holstein and buffalo cows were lower than for Nelore cattle; 2. leukocyte counts were similar among groups; 3. total protein levels of Nelore cows were lower than Holstein and buffalo. The albumin levels were rite lowest at rite time of calving compared to late pregnancy; 4. glicose levels were lower ill buffalo cows during pregnancy as compared with Holstein cows. The glicemia of Nelore cows was lower as compared to Holstein cow's irt late pregnancy; 5. urea and creatinine levels were higher in buffalo cows than cattle. The urea and creatinine levels were greater in buffalo cows with maximum values at the post-partum and at the parturition, respectively; 6. bilirrubin levels were higher in bovine than buffalo cows; 7. aspartate aminotransferase activity was greater in buffalo cows and increased at the time of calving; 8. alkaline phosphatase activity was increased during pregnancy and decreased after the time of calving; 9. gammnglutamyltransferase activity,vas the highest for buffalo cows after calving; IO. calcium levels were the highest for Holstein cows at the post-partum and the phosphorus levels were higher in buffalo cows, which had the highest magnesium levels at the parturation.

Constituintes sangüíneos de bovinos lactantes, desmamados e adultos das raças Nelore (Bos indicus) e Holandesa (Bos taurus) e de bubalinos (Bubalus bubalis) da raça Murrah

Blood samples from lactating, weaned and adult Holstein-Fresiean and Nelore cattle and Murrah buffaloes were tested through the study of hemogram and serum constituents. Red cell and leukocyte counts, and blood pH, fibrinogen, glucose, calcium, and phosphorus levels were similar in cattle and buffalo. Total protein, urea, creatinine, hemoglobin, magnesium, iron and aspartato aminotransferase and alanine aminotransferase activities were higher in buffalo than cattle. Leukocyte counts were higher for weaned Holstein cattle than for Nelore cattle but similar to buffalo and Nelore cattle had the lowest neutrophil counts. Bilirrubin levels were lower for buffalo than for cattle. Phosphatase alkalyne activities were lower for weaned buffalo than for other animals. Gammaglutamyltransferase activities were the highest for lactating and weaned buffalo.

Estimativa da mudança genética na produção de leite e gordura em bovinos da raça Holandesa

The objective of this study was to estimate the genetic trends of the milk and fat yield in three herds maintained in São Paulo State, Brazil. The estimation of genetic, environmental and phenotypic trends were based on 716 first lactations. The cows were sired by 134 bulls. The statistical models included the fixed effects of herds, kind of gestation, season and year of the calving, age of the cow at calving, besides the random effect of the bulls. The statistical analyses, by the last squares method showed effects for bulls, herds and age of the cows on milk and fat yield. The genetic, environmental and phenotypic trends estimated were -10.20; 6.74 and -3.46 kg for milk yield and -1.90; 2.20 and 0.12 kg for fat yield.

Produção científica na faculdade de filosofia, ciencias e letras de ribeirao preto-usp: Apliçãcao do índice de hirsch

In this work, an analysis of scientific bibliographic productivity was made using the Faculdade de Filosofia, Ciencias e Letras de Ribeirao Preto, Universidade de Sao Paulo (FFCLRP-USP) as example. It is a special Institution in the Brazilian University system which encompasses four important areas of knowledge (fields of concentration) in natural, biological, humanities, and social areas. It is composed by four departments which offer altogether eight undergraduate courses: 1) Psychology, 2) Pedagogy, 3) Chemistry, 4) Biology, 5) Medical Physics, 6) Biomedical Informatics, 7) Sciences of Information and Documentation and 8) Mathematics Applied to Business and six graduate programs leading to M.S. and Ph.D. degrees. Moreover, when analyzing the different courses of FFCLRP, they represent typical academic organization in Brazil and Latin America and could be taken as a model for analyzing other Brazilian research institutions. This analysis was made using: 1) the total number of papers (indexed in Curriculum Lattes database), 2) the number of papers indexed by Thomson ISI Web of Science database, and 3) the Hirsch (h-index). Bibliometric evaluations of undergraduate courses showed a better performance of the courses of Chemistry (P < 0.05), Biology (P < 0.05) and Medical Physics (P < 0.05) when compared to the Pedagogy, Sciences of Information and Documentation (P < 0.05) and Psychology (P < 0.05). We also analyzed the scientific output of the six graduate programs of FFCLRP-USP: 1) Chemistry, 2) Physics Applied to Medicine and Biology, 3) Entomology, 4) Compared Biology, 5) Psychology, 6) Psychobiology. The graduate programs in Psychobiology, Chemistry, Physics Applied to Medicine and Biology, Compared Biology, and Entomology presented very similar results, concerning the assessment of the three indexes. The graduate program in Psychology presented a lower h-index (P < 0.05) and had fewer papers indexed by the ISI (P < 0.05) when compared to the other graduate programs. The worse performance of the psychology program, pedagogy, sciences of information and documentation, psychology courses may be associated to the limited coverage of ISI database and some particular characteristics of this field of concentration.

Substituição dos grãos secos de milho pela silagem de grãos úmidos de milho para vacas da raça holandesa em lactação

In order to evaluate the effects of replacement of dried corn (GSM) for silage moisture corn (HMCS) on production and milk composition were used five Holstein cows, primiparous with a mean of 112 days post delivery, confined in Tie Stall, for 70 days. We used five diets according to NRC to 17.5% CP (DM) and 2.4 Mcal / kg DM, the 40:60 ratio of roughage and concentrate containing soybean meal, sugar cane silage and hay and substitution levels of the GSM HMCS the following treatments: a) 0%, 2) 25%, 3) 50%, 4) 75% and 5) 100%. Milk production and dry matter intake (DMI) were recorded daily. The animals were milked daily 6:00 and 18:00 h, and milk samples collected from consecutive milkings of each experimental period of 14 days (four days of collection). The experimental design was a 5x5 Latin square and the data analyzed by the statistical program SAS. Body weight (508 kg), milk (23.6 kg), corrected milk (22.7 kg), DMI (17.13 kg) showed no significant difference, but the intakes of neutral detergent fiber (6.67 kg), and detergent acid (3.39 kg), feed efficiency for the production of milk (milk 1.41 kg / day) urea nitrogen (17.67 mg / dL) differ, thus indicating that HMCS is more efficient than GSM in the diet of dairy cows not alter the production and milk composition.
