Reação de crisântemos a Meloidogyne incognita, Meloidogyne javanica e Meloidogyne enterolobii

This study aimed to evaluate the resistance of 14 chrysanthemum varieties to the nematodes Meloidogyne incognita, M. javanica and M. enterolobii. The experiment was conducted in a completely randomized design, consisting of 15 treatments and 4 replicates per nematode species. Each plot was constituted of one plant per pot; plants were kept in a greenhouse and inoculated with 5,000 eggs and possible juveniles of M. incognita, M. javanica and M. enterolobii. After 60 days, the rates of egg masses, the number of nematodes per gram of root and the reproduction factor were evaluated. The varieties showed immunity to M. incognita, M. javanica and M. enterolobii, except 'Capello Vermelho' and 'White Reagon', which were susceptible and resistant, respectively, to M. incognita.

High-fiber diets with reduced crude protein for commercial layers

This study aimed at evaluating diets containing different fiber sources and two crude protein levels on the performance, egg quality, and nitrogen metabolism of commercial layers. In total, 392 48-wk-old Isa Brown layers were distributed according to a completely randomized experimental design in a 3x2+1 (control) factorial arrangement, resulting in seven treatments with seven replicates of eight birds each. Treatments consisted of three fiber feedstuffs (cottonseed hulls, soybean hulls, and rice hulls) and two dietary crude protein levels (12% and 16%). Cottonseed hulls associated with the high crude protein level (16%) resulted in the worst feed conversion ratio per dozen eggs. Diets with 16% crude protein resulted in the highest feed intake, egg production, egg weight, egg mass values, and improved feed conversion ratio (kg eggs/kg feed). The dietary inclusion of soybean hulls determined low yolk pigmentation, and of rice hulls, low egg specific gravity. The 16% crude protein diet with rice hulls promoted the best feed conversion ratio. Hens fed the reference diet presented higher egg mass and better feed conversion ratio per kg eggs and per dozen eggs. Hens fed the diets with low crude protein level (12%) had reduced nitrogen excretion, but presented worse egg production.

Feed type for induced molting of commercial layer hens

An experiment employing three hundred and twenty 81-week-old Lohmann LSL commercial-breed hens was conducted to compare alternative induced-molting methods with the conventional method (fasting). Induced molting lasted 28 days at most, production and quality being monitored for four periods of 28 days thereafter. A completely randomized experimental design with five treatments, eight replicates of eight birds each per plot was adopted. The following experimental treatments were applied until a loss of 26% of body weight was reached: T1 - fasting, T2 - wheat bran ad libitum, T3 - rice bran ad libitum, T4 - cracked rice ad libitum, T5 - ground alfalfa ad libitum. Birds were then fed production diet ad libitum, except for those on treatment T1 (fasting) which received 30, 60 and 100 g/bird/day and then feed ad libitum. During induced molting the birds were exposed to a natural photoperiod and at day 28 that period was increased by 30 minutes/week until reaching 16 hours of light/day. The characteristics evaluated during induced molting were: feed intake, body weight changes and laying percentage. In the post-molt period, performance (feed intake, laying percentage, egg weight, egg mass, feed conversion ratio per dozen and per egg mass and percentage of broken eggs) and egg quality (specific gravity, eggshell breaking strength, percentages of eggshell, yolk, and albumen, eggshell thickness, yolk color and Haugh unit) were evaluated. Every 28 days one egg was collected from each repetition for three consecutive days for quality assessment. The use of rice bran and wheat bran is viable as molting inducers since the birds given those treatments display performance and egg quality similar to those fasted during the induced molting and also because these ingredients promote easier handling, eliminates the need for grinding and feed-mixing equipment and, being less aggressive, provide greater bird welfare.

LASIODERMA SERRICORNE (COLEOPTERA: ANOBIIDAE) IN STORED MATRICARIA RECUTITA (ASTERACEAE) IN BRAZIL

Insects pests of stored products and by-products are extending their feeding preferences to new items. We report for the first time in Brazil the feeding and reproduction of the cigarette beetle, Lasioderma serricorne F. (Coleoptera: Anobiidae) on stored chamomile, Matricaria recutita L. (Asteraceae). One intact package (10 cm wide x 15 cm long) of M. recutita infested by L. serricorne was purchased in a supermarket in Vicosa, Minas Gerais, Brazil. In this sample this insect had fed on the dried parts (inflorescences and rods), which made the product unfit for human consumption. This 20 g sample included 101 live and 4 dead Lasioderma serricorne. Circumstantial evidence suggested that the infested material was probably harvested from an infested field in Apr 2013 and packaged with L. serricorne eggs, and that these had developed into the adults found in the package.
