Sessenta e duas fêmeas eqüinas foram distribuídas ao acaso em dois grupos experimentais de acordo com o intervalo da penúltima à última inseminação artificial de cada ciclo (48h ou 72h). As éguas foram rufiadas e inseminadas às segundas, quartas e sextas-feiras, a partir do momento em que apresentavam um folículo de 3,0 a 3,5 cm de diâmetro, com sêmen de apenas um garanhão de fertilidade comprovada, diluído para um volume inseminante de 10 mL com diluidor de mínima contaminação. As taxas de concepção referentes ao primeiro ciclo, para os intervalos de 48h e 72h foram de 66,67% (24/36) e 65,22% (15/23), respectivamente, sendo as taxas de concepção/ciclo de 53,45% (31/58) e 56,76% (21/37), na mesma ordem anterior. Com base nos resultados obtidos, recomendam-se inseminações às segundas, quartas e sextas-feiras, sem perda da fertilidade.

Forty-two mares were randomly assigned in a 3 x 2 factorial experiment which included three intervals between rectal palpation (6/6h, 12/12h and once a day palpation) and two frequencies of inseminations (daily or every other day). The mares were inseminated with semen from only one stallion, diluted in minimal contamination extender. There were no differences in the conception rate at first cycle, conception/cycle, conception total, efficiency of pregnancy in either system of rectal palpation, independently of the frequency of insemination utilized. Also there were no differences among intervals of rectal palpation concerning the following reproductive characteristics: number of cycles/mare, cycles/pregnant mare, cycles/ pregnancy, pregnancy/cycle, number of inseminations/mare, inseminations/ pregnant mare and insemination/open mare. There were no differences in pregnancy rate at first cycle, pregnancy rate/cycle, pregnancy rate total and efficiency of pregnancy between the two frequency of insemination. However, the frequency of insemination influenced the number of inseminations/mare, number of inseminations/ pregnant mare and inseminations/open mare. The highest values were observed with the mares inseminated daily. Therefore, insemination every other day can be recommended. If necessary the mare may be palpated rectally at intervals of six hours without reducing the pregnancy rate.

Milk goats are indicated as an economic alternative for small farmers and cheese making could improve their profits. Goat's milk has a seasonal production characteristic and shows periods of abundance and others of scarcity. The use of frozen milk or frozen curd to make cheese can be used to solve the problem. The aim of this work was to evaluate the preparation of cheese made from mixed curd and ripened by Penicillium candidum mould using slow frozen milk (in a domestic freezer) or fast frozen milk (by liquid nitrogen). The slow frozen curd and fast frozen curd without whey were used. It was observed that the cheese from the slow and fast frozen milk and from the slow and fast frozen curd did not differ from the control cheese for the yield, chemicophysical characteristics, chemical composition, extention ripened rate, depth ripened rate and microbiological aspects, even when it was expressed as a dry matter content of cheeses.

The present study evaluated the effect of the use of natural antioxidants in different spent hens processed meat, the physical-chemical and sensory characteristics of product were analyzed. The experiment was conducted at the Technology Laboratory of Animal Products, Department of Technology - FCAV/Unesp - Campus of Jaboticabal. Forty-five laying hens with approximately 80 weeks of age were used, distributed in a completely randomized experimental design in a 4x4 factorial arrangement, 4 condiment types (control, rosemary, clove and oregano, and the last three natural antioxidants) and 4 storage times (0; 3; 6 and 9 days at 4°C), with sixteen treatments and tree repetitions. It were evaluated the characteristics of humidity, pH, color, cooking loss, shear force, TBARS number and sensory analyze. The averages were obtained by Tukey test 5% of significance. The results showed an interaction between the storage time and condiments types in all analyzed parameters. It was concluded that oregano use decreased the processed meat oxidation, also pleased the judges in sensory analysis. The lowest notes in sensory analysis were obtained with the treatment that contained clove.
