Abstract: the purpose of this research was to evaluate the concentration of tryglicerides, cholesterol, aspartate transaminase (ast) and progesterone (p4) in embryo donor nelore cows superovulated with different protocols. twenty four donors were randomly distributed in three groups: group 1 (n=11), donors superovulated with 500ui of fsh and group 2 (n=8) and group 3 (n=5) respectively with 200mg and 180mg of fsh, in decreasing doses, twice a day, during four consecutive days. blood samples were collected before superovulation (a), in the third day of superovulation (b), at the artificial insemination time (c) and at the embryo collection time (d). the concentrations of tryglicerides, aspartate transaminase (ast) and cholesterol were measured by spectrophotometry and progesterone (p4) by radioimmunoassay. there was no alteration (p<0.05) in the concentration of tryglicerides, ast and cholesterol among the samples. there was no effect (p>0.05) of the superovulation protocol on the concentration of tryglicerides, ast and p4 in the samples. in the samples a and b of group 2 the concentration of cholesterol was lower (p<0.05) than in groups 1 and 3, probably due to the instability of the parameter.

Abstract: The ovarian characteristics of pregnant and non pregnant zebu cows (Bos taurus indicus) were studied. The ovaries were obtained in slaughterhouses, identified and divided into: group I, non pregnant animals (GI, n=43) and group II, pregnant animals (GII, n=43). The ovaries were measured and cut in their lenght for measuring and evaluation of the corpus luteum (CL) characteristics. For the GI the measures for the left ovary were 2.5 ± 0.70, 1.61 ± 0.32 and 1.22 ± 0.39cm, respectively for length, width and thickness, and 2.62 ± 0.54, 1.71 ± 0.36 and 1.21 ± 0.31cm for the right ovary. For the GII the measures for the left ovary were 2.78 ± 0.48, 1.80 ± 0.33 and 1.23 ± 0.35cm, respectively for length, width and thickness and 2.84 ± 0.50, 1.74 ± 0.45 and 1.21 ± 0.40cm for the right one. Both groups presented 51.2% of CL in the left ovary and 48.8% in the right one, with high incidence of CL enclosed and without cavity. The mean for the diameter of the CL was 1.59±0.32cm for GI e 1.82±0.35cm for GII. The results suggest the need to consider carefully the size of the ovary and the enclosed characteristics of the CL when performing gynecological examination of zebu cows via rectal palpation.

Abstract: The objective this study was to evaluate the physical, physicochemical, morphological, mechanical and barrier properties of edible films obtained from pectin, sodium alginate or methylcellulose, aiming to evaluate their performance in minimizing the incorporation of oil. The pectin film presented the lowest water vapor permeability, thickness, water solubility, tensile strength, elongation and time for the film to change its color and size after contact with oil. The alginate film presented the greatest tensile strength and elongation and the lowest oxygen permeability. The methylcellulose film showed the longest time to change its color and size. The alginate film was the most indicated as a coating, since it showed the greatest tensile strength and elongation, which guarantees that the coating covers the chips uniformly and would have the least chance of rupturing during processing and it also shows low oxygen permeability making gas exchanges and oxidation of the final product more difficult.

Abstract: the clearance of long-acting progesterone in microspheres (p4la) in zebu animals and its potential for use in estrus synchronization were evaluated using 30 nelore and 30 crossbreed (holstein x zebu) heifers, with aging between 120 to 150-day-old and weighting 150kg in average. for each breed the animals were divided into three groups of ten animals each, gi= control group treated with saline; gii= treated with 450mg of p4la; and giii= treated with 750mg of long-acting progesterone (p4la). blood samples were colleted on days 0, 7 and 13 and analysed for progesterone using radioimmunoassay in solid phase. the serum concentration of progesterone was different on days 0, 7 and 13 in relation to the dose of p4la given. all treated animals presented basal values for progesterone on day 0, increased on day 7 and decreased on day 13, but with values over 1ng/ml. the results show that the drug was absorbed rapidly after its administration and remained in satisfactory concentration in the circulation until day 13. the average total concentration of serum progesterone was higher in nelore heifers when compared to the concentration in crossbreed ones, indicating difference in the metabolism of the drug between the two genetic groups.

Abstract: morphological changes in the placenta at periparturition and the involvement of apoptosis controlling cell populations in the placentome were evaluated in holstein and nelore cows. twenty-two holstein cows at the end of gestation with normal non-induced parturition (group i) and 10 holstein cows with induced parturition (group ii) were used in this study. in addition, groups iii and iv were constituted by 10 nelore cows at the end of gestation with normal non-induced parturition and 21 nelore cows with induced parturition, respectivelly. binucleate trophoblastic cells, epithelial caruncular cells and apoptotic bodies were quantified by light microscopy. apoptosis was further evaluated by transmission electron microscopy, elisa and dna electrophoresis in agarose gel. the number of caruncular epithelial cells did not vary between breeds with normal or induced parturition. the number of binucleate cells was significantly different between holstein and nelore cows with normal non-induced parturition (groups i vs. iii), but their numbers were not significantly different between breeds when parturition was induced. in cows with normal non-induced parturition, the intensity of apoptosis, as assessed by morphometric analysis and elisa, was significantly higher in group i when compared to group iii. however, no difference in the intensity of apoptosis was found between groups ii and iv. characteristic apoptotic ladder pattern of dna fragmentation was detected by agarose gel electrophoresis. ultra-structural features of apoptosis in maternal and fetal epithelium as well as capillary vascular endothelium were identified by transmission electron microscopy. in conclusion, in nelore placental maturation occurs precociously when compared to holstein. in both breeds, apoptosis is an active physiological event that seems to be required for maturation and normal post-partum release of the placenta.

Abstract: twenty-four nelore bulls (bos taurus indicus) were divided in three groups of eight animals each according to ep: group 1 - ep above average (ep>22.8cm); group 2 - ep 5% below average (ep between 21.6 and 22.6cm); and group 3 - ep from 10 to 5% below average (ep between 20.1 and 21.2cm). for the aol and eg analysis the 24 animals were divided in two groups: g1 (more precocious) and g2 (less precocious), classified according to the age in which each animal reached puberty. g1 presented greater ep at puberty and less weight in comparison to g2 and g3. the aol measures did not present difference between g1 and g2 groups. the animals in g1 reached puberty at a younger age, while the fat deposition occurred in g2. the use of productive characteristics in a program to select animals for sexual precocity can constitute a great advance for cattle productivity, increasing the genetic gain and decreasing production costs.

In die Skriflig , 2002, DOI: 10.4102/ids.v36i3.513
Abstract: The preacher and his task of equipping the congregation: Basis-theoretical perspectives from the Hebrews sermon In this article an attempt is made to indicate that preachers should be conscious of their task of equipping the congregation. Expressions in which the preacher, his conduct, his relation to other people and his spirituality are stated explicitly are investigated. The authors deal with basis-theoretical material taken from Hebrews. In the Hebrews sermon the preacher is indicated as therapist, leader, minister and shepherd. The preacher is also perceived of as servant and mouthpiece in the liturgy of the congregation. This exposition is followed by perspectives for the praxis of equipment in ministering the Word to the congregation.
Prediking en die gesindheid van hoorders. Basisteoretiese perspektiewe vanuit Hebre rs

Abstract: Preaching and the attitude of hearers. Basis-theoretical perspectives from the Hebrews sermon The issue dealt with in this article is the extracting of certain basistheoretical perspectives from Hebrews, reminding preachers and hearers that preaching and attitude are interrelated concepts. Expressions in which preaching and attitude are stated explicitly are investigated, and concepts indicating certain dimensions of attitude as reflected in the Hebrews sermon are discussed. This exposition is followed by selected perspectives for the praxis of equipment in ministering the Word to the congregation.
