Development of an L-Lysine Enriched Bran for Animal Nutrition via Submerged Fermentation by Corynebacterium glutamicum using Agroindustrial Substrates BABT
Letti Junior,Luiz Alberto; Letti,Gilberto Vinícius Melo; Soccol,Carlos Ricardo.
L-Lysine is an essential aminoacid added as supplement for animal feed. The aim of this work was to produce an L-Lysine enriched bran using Brazilian agroindustrial byproducts. Both the raw material costs and purification steps were minimized. Firstly, medium composition for the growth of Corynebacterium glutamicum ATCC 21799 was optimized targeting enhanced L-Lysine production - salt, vitamins and nitrogen sources concentrations were tested and selected. Next, UV mutant strains were generated and the best producers were used in formulated media using sugarcane molasses. It was reached a production of 9.3 g/L of L-Lysine with the optimized formulated media. This L-Lyisne rich broth was then impregnated and cyclically reimpregnated in pre-treated solid...

Silage of the agro-industrial co-product of babassu palm heart processing in sheep feed Ciência Rural
Codognoto,Luciane da Cunha; Porto,Marlos Oliveira; Conde,Thassiane Telles; Cavali,Jucilene; Ferreira,Elvino.
ABSTRACT: The inner bark or less tender sheath generated from industrial manufacture of canned babassu palm (Attalea speciosa) heart is inadequate for human consumption, often being discarded inappropriately and giving rise to environmental pollution. Accordingly, the aim of this study was to assess the intake and digestibility in sheep fed on silage of the agro-industrial co-product of babassu palm (ICBP)enriched with different additives, or on sugarcane silage. Fifteen Santa Inês sheep were distributed in a completely randomized design, consisting of five treatments and three replicates. The treatments comprised babassu palm silage enriched with broken maize (BM), broken rice (BR), cassava scrapings (CS), coffee husk combined with maize kernel (CC), and...

Millet and corn oil in sorghum-based diets for broilers Ciência Rural
Bueno,João Paulo Rodrigues; Nascimento,Mara Regina Bueno de Mattos; Carvalho,Carolina Magalhães Caires; Fernandes,Evandro de Abreu; Silva,Marina Cruvinel Assunção; Martins,Julyana Machado da Silva; Litz,Fernanda Heloisa.
ABSTRACT: This study evaluated the effects of millet and corn oil additions to sorghum-based diets on the performance, carcass yields and prime cuts (i.e., wings, breasts, thighs and drumsticks) and the relative weights of edible offal (i.e., gizzard, heart, and liver) of broiler chickens. A total of 684 Hubbard Flex chickens, including 342 broilers of each sex, were housed. The design was completely randomized, and the following diets were supplied: A) sorghum and soybean meal + soybean oil (control); B) sorghum and soybean meal + corn oil; and C) sorghum and soybean meal + millet and soybean oil. Six replicates with 38 birds each (19 males and 19 females) were evaluated regarding each experimental diet. At 14, 21, 35 and 42 days of age, the feed intake,...

Performance and meat chemical composition of quails fed with different sorghum levels instead of corn Ciência Rural
Moraes,Cíntia Amaral; Fernandes,Evandro de Abreu; Silveira,Márcia Marques; Martins,Julyana Machado da Silva; Litz,Fernanda Heloisa; Saar,Anna Gabriella Lima; Carvalho,Carolina Magalhães Caires.
ABSTRACT: The objective of this study was to evaluate the effect of replacing corn with sorghum in feed on performance, carcass yield, and composition of specialized meat cuts in quails. A total of 1200, 1-day-old female quails were raised up to 42 days of age. The completely randomized design consisted of four treatments with six replicates each and with 50 quails in each cage. Treatments consisted of four levels of sorghum replacement in the diet (0, 40, 60, and 100% sorghum). All birds were weighed to assess the weight gain. Feed conversion was calculated as the relationship between feed intake and weight gain. Mortality was reported daily and calculated at the end of each week. At 42 days, the birds were slaughtered and the carcass, thigh and...
