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.

Sistema orgânico de produção de pescado de água doce

This study aimed to collect data about organic production of freshwater fish. Today the production of organic food of plant origin is predominant in the market, however, the animal rearing with organic certificate has great potential, and is an important tool for adding value to grains and organic products. Regarding the regulation of organic aquaculture, producers are based on international standards. In Brazil, the norms for breeding are very recent and their regulation was consolidated through Interministerial Instruction No28, published on June 8, 2001 by Ministério da Agricultura, Pecuária e Abastecimento (MAPA) together with Ministério da Pesca e Aquicultura (MPA). In the literature there are few studies with organic fish farm, but according to available data, the rearing of species such as tilapia (Oreochromis niloticus), pacu (Piaractus mesopotamicus) and jundia (Ramdhia sp) fed with organic diet, in different rearing systems, show results quite optimistic about the production system, which is the focus of this work.

Unidade amostral para determinação de massa média de frutos em lichieira em sistema orgânico e convencional

The experimental unit of measurement is a suitable technique to estimate the average character in evaluation, and experimentation should be well understood and executed, because the precision characterizes the quality of the inferences of the results. This research aimed to analyze the possibility to obtaining the quantity of fruit required for sampling of lychee plants, to determining the average mass of the fruits, with less sampling error. One hundred fruits were collected, in a hectare, in two cropping systems, conventional and organic, being one fruit per plant. From the data of fruit mass was used the Excel® to calculate the average fruit mass and number of fruits samples needed to represent the area of the producer. The results show that to achieve a sampling error of 10% for determining the average mass of fruit, 400 fruits should be collected for organic system and 370 for the conventional, while for 20% sampling error, it is necessary to collect 250 fruits per hectare in organic system and 220 in the conventional.
