The aim of this study was to determine the viability and nutritional characteristics of shrimp head silage and fish waste destined for pig feeding. In the conservation process, molasses and rice powder were used as a substrate and Lactobacullus fermentus, obtained from the digestive tract of the piglet, as a fermenter. Temperature, pH and percentage of acidity data were recorded, as well as organoleptic and nutritional characteristics in the first 30 days of conservation. The treatments were T1 = Shrimp head with molasses and yogurt; T2 = Shrimp head with rice powder and yogurt; T3 = Fish residue with molasses and yogurt; and T4 = Fish residue with rice powder and yogurt. T1 and T3 presented acidity and low pH, as well as low temperature during the first week, stabilizing the process on day 15. The fermentation of T2 and T4 was inadequate (not feasible). Aerobic mesophilic microorganisms...

The aim of the study was to isolate and identify native lactobacillus microorganisms from the digestive tract of piglets with the possibility of using them for the improvement of the productive performance of piglets. Samples were cultured and purified on Man, Rogosa and Sharpe (MRS) agar. Molecular identification of the bacteria was done by the sequencing the 16S rRNA gene. Four species were identified: Lactobacillus johnsonii, Lactobacillus brevis, Enterococcus hirae and Pediococcus pentosaceus.

The composition and abundance of the bacterial microbiota in three portions of the gastrointestinal tract of a piglet, in the balanced feed and in biological ensilages prepared with residues of aquaculture origin were evaluated by metagenomic analysis. The DNA of the samples was extracted, and sequenced. The greatest bacterial diversity was in the balanced feed (44.7%), with the predominance of Candidatus phytoplasma surgarcane. In the biological silage predominated Lactobacillus casei and Lactococcus lactis. The existing diversity was similar between silage and the concentrate feed. Similarities were found between the bacteria of the three gastrointestinal regions (L. ultunensis, Selenomonas bovis, Prevotella copri, Enterococcus lactis y Campylobacter sp). In the stomach predominated Helicobacter rappini and Campylobacter coli, in the small intestine Selenomonas bovis and Lactobacillus ...

The aim of this study was to determine the viability and use of the biological silage (BE) of shrimp head, molasses and milk fermented with lactic acid bacteria (75-25-5, respectively), providing it as feed for backyard pigs and its leachate as organic fertilizer in the cultivation of maralfalfa grass. It was tested by adding to a base diet for pigs, daily at levels of 0%, 5%, 10 and 15% of the BE and as fertilizer in doses of 300, 500, 700 L/ha (leached) and control (100 nitrogen units) in three applications at 0, 30 and 60 days of installation. Vegetative seed was used in 16 pools of 22 m2, evaluating the main productive parameters at 30, 60 days and at harvest (90 days), 40 growing animals (20 kg) were evaluated in pigs for 35 days. The EB and its leachate were viable and stabilized after 15 days of preparation (pH less than 4.5), presented adequate values as feed for pigs according t...

The aim of this study was to evaluate the repellent efficacy for mosquitoes (Anophelex spp) of three doses of neem oil (Azadirachta indica A. Juss) in pigs under field conditions. The research was carried out at a time of year of abundance of mosquitoes in Tumbes, Peru. Forty recently weaned piglets were used, 10 per treatment, kept in indoor cages protected against mosquitoes. For the field test, four piglets per day were exposed randomly in external cages without protection to the mosquito (a different animal for each treatment per day) for 14 days over a period of two months. Neem oil was extracted with the soxhlet apparatus and the formula included 30% glycerin, 1, 2 or 3% neem oil (T1, T2, T3, respectively), and taken to 100% with pharmaceutical alcohol. A dose of 50 ml/piglet distributed throughout the body was applied. The bites and the number of mosquitoes were evaluated on four ...
