Produção leiteira de búfalos.

O búfalo é um animal com aptidão para produção de carne e leite, além de ser utilizado como força de trabalho no campo. Em razão de sua elevada rusticidade e capacidade de adaptação em solos de baixa fertilidade e terrenos alagadiços, bem como sua capacidade de converter alimentos de baixa qualidade em proteína de qualidade, esses animais têm ocupado regiões que são consideradas inadequadas para a criação de bovinos.bitstream/item/217369/1/cpafro-18470.pd

Avaliação preliminar do desenvolvimento ponderal de bovinos F1 (Valdostana X Nelore) e Nelore do nascimento ao desmame, no Estado do Acre.

Foram estudados peso ao nascer (PN), peso à desmama (PD, 205 dias) e ganho de peso do nascimento à desmama (GPND) do rebanho de 75 Nelore e 107 cruzados de Valdostana x Nelore. Os dados foram coletados de 2000 a 2001 da Fazenda São Luiz, Capixaba-Acre. No modelo estatístico foram incluídos os efeitos fixos da raça (R), condição corporal da vaca (CC), mês do parto (MP) e as co-variáveis diferença entre o peso da matriz ao parto e cobertura (DPPC) e a idade da vaca (IV) com efeitos linear e quadrático. Os dados foram submetidos a análises estatística usando o procedimento GLM do programa SAS. As médias e seus desvios-padrão para as respectivas raças foram: PN 34,69±0,90(N) e 32,85±0,91(V); PD 212,93±4,15(N); 215,75±4,47(V); GPND 0,87±0,029(N); 0,89±0,02(V). Foram significativos (P<0,05) os efeitos de raça sobre PN, de CC (P<0,01) sobre PN e (P<0,05)) sobre PD e a DPPC (P<0,01) sobre PD e GPND. As médias encontradas foram superiores aquelas relatadas por outros autores em regiões diferentes, estudando animais Nelore e seus cruzamentos com animais de raças européias. Preliminary study on growth traits of F1 (Faldostana x Nellore) and nellore cattle from birth to weaning in the state of Acre ABSTRACT: Birth weight (BW), weaning weight (WW, 205 days) and daily gain from birth to weaning (GBW) of 75 Nellore and 107 crossbred Valdostana x Nellore cattle were investigated. Data were collected from 2000 to 2001 at "Fazenda São Luis", Capixaba-Acre. The model included the fixed effects of breed of bulls (R), corporal condition of the cows (CC), month of birth (MB) and, as covariates, the difference between the weight of the cow at parturition and at insemination (DWPI) and the age of cow (AC) as linear and quadratic. Data were submitted to statistical analyses using the procedure GLM of SAS program. Least squares means and standard errors of Nellore and Valdostana x Nellore were respectively: BW 34.69±0.90 and 32.85±0.91; WW 212.93±4.15; 215.75±4.47; GBW 0.87±0.029; 0.89±0.02. Significant differences were found among: breeds (P<0.05) for BW; CC (P<0.01) for BW and (P<0.05) for WW; DWI (P<0.01) for BW and GBW. The values found in the present work were higher than those reported in other papers that investigated on Nellore cattle and its crosses with European breeds raised in different regions

Reproducibility Analysis Of The Stability And Treatment Of Vertebral Metastatic Lesions

Objectives: To investigate the reproducibility among spine surgeons in defining the treatment of vertebral metastatic lesions, taking into account the mechanical stability of injuries. Methods: Twenty cases of isolated vertebral metastatic lesions were presented to ten experts. Their opinion was then asked about the stability of the lesion, as well as their treatment option. Results: The interobserver Kappa coefficient obtained both for stability analysis as to the decision of the treatment was poor (0.334 and 0.248, respectively). Conclusions: Poor interobserver reproducibility was observed in deciding the treatment of vertebral metastatic lesions when considering the stability of the lesions.133232234American Cancer Society, (2007) Cancer Facts and Figures, , Atlanta: American Cancer SocietyNewman, C.B., Keshavarzi, S., Aryan, H.E., En bloc sacrectomy and reconstruction technique modification for pelvic fixation (2009) Surg Neurol, 72 (6), pp. 752-756Harrington, K.D., Current concepts review: Metastatic disease of the spine (1986) J Bone Joint Surg Am, 68 (7), pp. 1110-1115Gasbarrini, A., Cappuccio, M., Mirabile, L., Bandiera, S., Terzi, S., Barbanti Bròdano, G., Spinal metastases: Treatment evaluation algorithm (2004) Eur Rev Med Pharmacol Sci, 8 (6), pp. 265-274Bilsky, M., Smith, M., Surgical approach to epidural spinal cord compression (2006) Hematol Oncol Clin North Am, 20 (6), pp. 1307-1317Weber, M.H., Burch, S., Buckley, J., Schmidt, M.H., Fehlings, M.G., Vrionis, F.D., Instability and impending instability of the thoracolumbar spine in patients with spinal metastases: A systematic review (2011) Int J Oncol, 38 (1), pp. 5-12Tokuhashi, Y., Kawano, H., Ohsaka, S., Matsuzaki, H., Toriyama, S., A scoring system for preoperative evaluation of the prognosis of metastatic spine tumor (a preliminary report) (1989) Nihon Seikeigeka Gakkai Zasshi, 63 (5), pp. 482-489Tokuhashi, Y., Matsuzaki, H., Toriyama, S., Kawano, H., Ohsaka, S., Scoring system for the preoperative evaluation of metastatic spine tumor prognosis (1990) Spine (Phila Pa 1976), 15 (11), pp. 1110-1113Tomita, K., Kawahara, N., Baba, H., Tsuchiya, H., Fujita, T., Toribatake, Y., Total em bloc spondylectomy.

Contagem de células somáticas do leite total de rebanhos mestiços leiteiros do estado do Acre - nota prévia.

As células somáticas encontradas no leite são parte da resposta inflamatória e são constituídas, em sua maioria, por leucócitos que se originam no organismo do animal e têm como principal função combater infecções bacterianas que se instalam na glândula mamária. Células epiteliais, originadas da glândula mamária, constituem de 2 a 20% das células somáticas. Dessa forma, a contagem de células somáticas (CCS) é um elemento adequado para se avaliar o estado de saúde da glândula mamária dos rebanhos

Nutritional requirements of energy, protein and macrominerals for maintenance and weight gain of young crossbred Nellore × Holstein bulls on pasture.

The objective of this study was to estimate requirements of energy, protein and macrominerals of young Nellore/Holstein crossbreds bulls supplemented on pastures of Brachiaria decumbens Stapf. Thirty-five young bulls, at 8.53±0.18 months of age and with initial body weight of 230.6±6.1 kg were used. Ten animals were slaughtered as reference, in different weight range, and the other animals were slaughtered at the end of the experimental period. For estimate of net energy requirements for weight, a regression equation between log of retained energy (RE) and log of empty body weight gain (EBWG) was constructed. Net requirements of Ca, P, Mg, Na and K were determined by the equation Y' = a.b.Xb-1, in which a and b represent the intercept and the coefficient of equation of prediction of macrominerals in body content, respectively. Requirements of metabolizable energy for maintenance (MEm) were obtained from retained energy in function of metabolizable energy intake (MEI). The requirements of MEm of Nellore/Holstein crossbreds young bulls on pasture was 125 kcal/EBW0.75/day. The efficiency of ME utilization for maintenance (km) of grazing Nellore/Holstein crossbred young bulls was 0.58 and 0.24 for gain. The total metabolizable protein requirements for an animal with 400 kg and with average daily gain of 1.0 kg, were 638.36 g/day. The dietetic requirements of Ca and P for an animal with 400 kg BW were 0.49 and 0.21% of DM, respectively. Daily metabolizable energy requirement for maintenance of grazing Nellore/Holstein crossbred young bulls was 11.6% greater than the values found for cattle in feedlot in Brazil (112 kcal/kg EBW0.75)

Experimental rations were balanced for reaching levels of 22.0 % of crude protein (CP) and 80.1 % of total digestible nutrient (TDN)

The Crystal Ball Data Acquisition System

The data acquisition system for the Crystal Ball project at SLAC is described. A PDP-11/t55 using RSX-11M connected to the SLAC Triplex is the basis of the system. A "physics pipeline" allows physicists to write their own equipment-monitoring or physics tasks which require event sampling. As well, an interactive analysis package (MULTI) is in the pipeline. Histogram collection and display on the PDP are implemented using the Triplex histogramming package. Various interactive event displays are also implemented
