The objective of this review is to conduct a survey on the main concepts related to dog and cat nutrition in the different life stages. The market for pet products and services has been expanding worldwide and is a lucrative new segment of the economy. Advances in research with pet nutrition have occurred to meet a growing demand both for product innovation that catches the attention of owners and animals, as well as for ensuring that nutritional requirements are met at each age and a better quality of life. Dogs and cats present themselves as carnivores, but with habits and food forms often classified as an omnivorous species, with carnivorous cats being strict and dogs being facultative. Just like the human diet, dogs' health depends on a correct and balanced diet that contains a broad set of nutrients to meet all daily needs. Functional foods encompass both foods and ingredients that have the basic nutritional functions and also produce metabolic and / or physiological health benefits. The addition of functional ingredients to dog and cat foods is already a reality in the nutrition of pets. In addition, there are a variety of food products for dogs and cats, being classified as dry, moist and semi-moist.

Objetivou-se avaliar os efeitos da inclusão de diferentes níveis de açafrão em pó (Curcuma longa L.) na ração de frangos de corte em comparação ao antibiótico promotor de crescimento. Foram utilizados 720 pintos de corte de 1 dia, da linhagem Cobb, distribuídos em delineamento inteiramente casualizado, em arranjo fatorial 5x2 (cinco tratamentos e dois sexos), com quatro repetições e 18 aves por unidade experimental. Os tratamentos foram: ração basal (RB) + 150 g/kg de bacitracina de zinco, RB sem aditivos, RB + 3,3 g/kg de açafrão, RB + 6,6 g/kg de açafrão e RB + 10 g/kg de açafrão. Avaliou-se o desempenho (peso vivo, consumo de ração, ganho de peso, conversão alimentar e mortalidade), rendimento de carcaça, peso relativo de vísceras e a rentabilidade econômica. Os dados obtidos foram submetidos à ANOVA e as médias dos tratamentos submetidas à análise de regressão e teste de Dunett a 5%. As aves alimentadas com açafrão não apresentaram diferenças entre as variáveis de desempenho, rendimento de carcaça e peso relativo de vísceras, quando comparadas às aves suplementadas ou não com antibiótico. A inclusão de 3,3 g/kg de açafrão apresentou índice de rentabilidade semelhante ao tratamento RB + 150 g/kg de bacitracina de zinco. Portanto, a suplementação de açafrão em pó na dieta de frangos de corte tem ação no desempenho produtivo, no rendimento de carcaça e de cortes nobres, peso relativo de vísceras e comprimento de intestinos das aves semelhante ao antibiótico promotor de crescimento, sendo o nível 3,3 g/kg o que apresenta a melhor rentabilidade econômica. Palavras-chave: aditivo fitogênico; Curcumina; promotor de crescimento; rendimento de carcaça; viabilidade econômica. TURMERIC POWDER (Curcuma longa L.) IN THE FEED OF BROILER ABSTRACT This study aimed to evaluate the effects of inclusion of different levels of turmeric powder (Curcuma longa L.) in the feed of broilers. 720 Cobb broiler chicks of 1 day were used, distributed in a completely randomized design in a factorial arrangement 5x2 (five treatments and both sexes), with four replications and 18 birds per experimental unit. The treatments were: basal diet (BD) + 150 g/kg of zinc bacitracin, BD without additives, BD + 3.3 g/kg of turmeric, BD + 6.6 g/kg of turmeric and BD + 10 g/kg of turmeric. Were evaluated performance (live weight, feed intake, weight gain, feed conversion and mortality), carcass yield, viscera weight and economic profitability. The data were submitted to ANOVA and means of treatments submitted to regression analysis and test Dunett 5%. Broilers fed with turmeric showed no differences between the performance variables, carcass yield and relative weight of viscera when compared to birds supplemented or not with antibiotics. Inclusion of 3.3 g/kg of turmeric presented profitability index similar to the treatment RB + 150 g/kg zinc bacitracin. Therefore, supplementation of turmeric powder in broiler diet has action on productive performance, carcass yield and the relative weight of viscera and length of the intestines of birds similar to the...

This review was carried out with the purpose of describing the main reproductive management used in the rearing of pigs. Currently, swine breeding in Brazil has average production parameters of 9.5 piglets / calving with 1.9 calving / year, with a genetic potential to reach 13 piglets / calving with 2.6 calving / year. To obtain these zootechnical indexes in pig production, it is necessary to invest in reproductive technologies such as artificial insemination, adequate facilities and frequent training of the workforce. In this sense, to be successful in reproduction, it becomes necessary to know the anatomy and physiology of the male and female reproductive system. The good reproductive performance of the animals also depends on the criterion of selection of the boar and the matrices applied in the breeding. It is fundamental to know the estrous cycle, as well as, the behavior of the nut in estrus to obtain success in artificial insemination or natural mating. The gestation period, as well as childbirth, are critical breeding phases and should be well conducted with the aim of avoiding or reducing piglet mortality. Therefore, the reproductive stages of pigs should be well conducted with special attention to food and sanitary management. The knowledge of the reproductive management by the producer and / or technician responsible for the farm is of fundamental importance to achieve good productive indexes
