Alimentação de leitões com dietas contendo soro de leite fermentado mais zinco e cobre orgânico

An experiment was carried out to evaluate the performance of piglets fed rations containing fermented milk and zinc and copper amino acid complex. Sixty four piglets, littermates, were used. The experimental design was based on random block with two dietary treatments. One of these contained a basal diet (DB) with ZnO e CuSO 4 and the other one with the DB, but without CuSO 4 and with the addition of fermented milk and zinc and copper amino acid complex (SLF Lact +ZnCuAA). There were eight replicate pens per treatment, and pigs were grouped at 4 per pen. The SLF Lact + ZnCuAA didn't not affect (p>0.05) final live weight of the piglets. However, live weight was different (p<0.01) between males and females (24.3 vs. 24.0 kg) at end of experiment. The feed intake of animals feed with SLF Lact+ZnCuAA was higher (p<0.01) in 8% in the first 14 days (0.261 vs. 0.239 kg/d), 15% from 15 to 28 days (0.756 vs. 0.675 kg/ d) and 12% from 29 to 42 days (1.091 vs. 0.962 kg/ d) compared to control group. Daily average feed intake in the experimental period was 11% higher (p<0.01) for the animals fed with the diet contained SLF Lact+ZnCuAA. Weight gain of the treatment with SLFL act+ZnCuAA was higher (p<0.01) by 14% from 0 to 14 days (0.176 vs. 0.152 kg/d), 11% from 15 to 28 days (0.564 vs. 0.500 kg/d) and 12% from 29 to 42 days (0,572 vs. 0,501 kg/d). Average daily weight gain of 42 days of trial of treatment with SLF Lact +ZnCuAA was 12% higher (p<0.01) compared to control group (0.437 vs. 0.384 kg/d). Feed conversion ratio was 8% lower (p<0.01) for treatment with SLF Lact+ZnCuAA in the first 14 days (1.487 vs. 1.614). Supplementation with fermented milk and zinc and copper amino acid complex in diets containing zinc oxide improved growth performance of weanling piglets.

Artemia sp. na alimentação de larvas de jundiá (Rhamdia quelen)

A considerable problem in the catfish larvae rearing is related to the first feeding. This study aimed to determine the larvae growth and the survival of silver catfish submitted to feeding with Artemia sp. in different time periods. The study was conducted in the Aquaculture Laboratory of the Universidade Estadual do Oeste do Paraná, with four treatments and five replications, constituted by feeding with Artemia sp. in 5, 10, 15 and 20 days, and after each period of time, by its replacement by ration. We used 200 larvae distributed into 20 aquariums, soon after the eggs hatched. The larvae were fed 4 times a day until apparent satiation for 30 days. The Artemia sp. feeding for 15 days provided the best results on weight gain, final length and survival.

Desempenho e morfometria duodenal de frangos de corte submetidos a diferentes níveis de energia e programas de alimentação de 42 a 57 dias de idade

This experiment was conducted to evaluate the use of different energy levels and amino acid recommendations on performance, carcass yield and intestinal morphometry of broilers from 42 to 57 days of age. We used 1,600 one-day old male broilers (Cobb 500) in a completely randomized design arranged in a 2x4 factorial scheme with 3,200 and 3,600 kcal ME/kg and four different feed programs. The metabolizable energy levels and the feed programs did not determine significant differences in carcass characteristics for choosing a level of energy or a feed program, thus the energy level and the recommendations of amino acids that determine the highest cost-benefit ratio should prevail. It was observed that 3,600 kcal ME/kg resulted in some improvement on performance and morphometry of the intestinal mucosa, also the fractioning of digestible amino acid requirements during two periods resulted in worse performance and intestinal villi height.

Efeito de cultivares de repolho e doses de extrato aquoso de nim na alimentação e biologia de Plutella xylostella (linnaeus) (lepidoptera: Plutellidae)

The isolated and associated effects of cabbage cultivars Ruby Ball and Chato de Quintal and aqueous extract of seeds of fruits of neem (Azadirachta indica A. Juss.) were evaluated in the concentrations of 5 and 10% on Plutella xylostella (L.) attractiveness, feeding and development. In free-choice no-preference for feeding test, leaf discs of each treatment were placed in Petri dishes where three caterpillars/treatment were released while in no-choice test two caterpillars were placed in Petri dishes with one leaf disc in each dish. In the biology test, neonate larvae were transferred to Petri dishes in the proportion of one per dish, whereas the biological parameters were evaluated: larvae mortality after 1, 3 and 5 days; pupae mortality; total mortality; six day-old larvae weight; 24 hour-old pupae; and adult longevity. Cultivar Ruby Ball showed lower attractiveness to the caterpillars in free-choice test. Neem extract in both concentrations was repellent to the caterpillars in free-choice test. There were no differences in the dry mass consumed by the caterpillars in free-choice and no-choice tests. There were no differences in larval, pupal and total mortality between the cultivars. Both doses of neem extract were equally efficient in the mortality of the diamondback moth. There were no differences in caterpillars and pupae weight and in the longevity of the adults of P. xyostella between the cultivars.
