    Abstract: In order to evaluate the kinetics of ruminal digestion by means of the in situ incubation tectonics of the dry matter (DM), crude protein (CP) and neuter detergent fiber (NDF) of isoenergetic and isoprotein rations with 16% of crude protein with different levels (0, 10, 20, 30 and 40%) of replacement of ground corn with straw and cob (GCSC) for coffee hull, an experiment was conducted at the Department of Animal Science of the Universidade Federal de Lavras - UFLA - Lavras - MG, Brazil, with three non-lactating cows of the holstein breed, fitted with ruminal cannulas into which samples of forage, coffee hull, CGSC and experimental rations for 0, 6, 12, 24, 48, 72 and 96 hours were incubated. The data obtained about the degradability were fit for a non-linear regression by Gauss-Newton's method. The data obtained allowed to evaluate that with increasing levels of coffee hull, the effective degradability of the dry matter of the rations proved similar to that of the ration without that residue, a trend of increased effectively degraded protein being also observed. But with neuter detergent fiber the effect was the reduction of effective degradability. Based upon this experiment, it follows that the replacement of GCSC for coffee hull up to the level of 40% did not affect the effective degradability of both the dry matter and crude protein of concentrates. Nevertheless, it reduced the effective degradability of neuter detergent fiber.

    Abstract: The experiment was carried out at the Department of Animal Science of the Universidade Federal de Lavras and at the Food Laboratory at the Universidade José do Rosário Vellano (UNIFENAS), with the objective to evaluate the nutritive value of cotton textile mill waste using chemical composition (DM, CP, NDF, ADF) and ruminal degradability of the dry matter and NDF. The treatments were: T1 - in natura residue (IN); T2 - residue submitted to the pressure and steam treated (127ºC/1,5 kgf/cm²/35"; PS); T3 - 4% sodium hydroxide treated residue (four 24 hours; NaOH); T4 - 3% urea treated residue (for 28 days; U); T5 - 4% NaOH +3% urea treated residue (NaOH/U); T6 - pressure and steam + 4% NaOH treated residue (PS/NaOH); T7 - pressure and steam + 3% urea treated residue (PS/U). The results obtained in the chemical composition can allow concluding that combined treatments improved the nutritive value of the residue, as the NaOH/U treatment showed better results of CP, NDF, ADF. In the degradability experiment, it may be concluded that PS, U, NaOH/U, PS/NaOH and PS/U treatments were efficient in increasing effective degradability of DM, also resulted higher dry matter soluble fraction (a) and lower insoluble potentially degradable fraction (b). The treatments U, PS/NaOH and PS/U had higher values of effective degradability of NDF and higher soluble fraction (a). The combined treatments increased the degradability and nutritive value of cotton textile mill waste, and combined treatments with urea had the better results.

    Abstract: The objective of the experiment was to evaluate the bio-conversion treatment to enhance the nutritional value and degradability of cotton textile mill waste, using the fungi Pleurotus sajor-caju. The experiment was conducted at the Departments of Biology and Animal Science of the Universidade Federal de Lavras (UFLA), between July 2002 and January 2003. Bio-conversion was induced by the use of the residue as the main component in a substrate bed for cultivation of edible mushrooms (C1 and C2). In comparison to the untreated cotton textile mill waste, two bio-conversion alternatives by Pleurotus sajor-caju were tested. After mushroom production, samples of the treated material were submitted to in situ degradability tests and chemical composition. Results indicated that C1 and C2 treatments decreased fibrous fractions (ADF and NDF) and increased CP of cotton textile mill waste, improving the chemical composition. C1 and C2 treatments also resulted in an increased of soluble fraction (a), the degradation rate (c), and decreased insoluble potential degradable fraction (b); increasing effective degradability of DM and NDF of cotton textile mill waste.

    Abstract: The experiment was conducted to investigate the viability of the production of the edible fungus Pleurotus sajor-caju (Fr.) Singer in substrates in which main source of carbon was the cotton textille mill waste. Two substrates compositions were tested: C1 (cotton textille mill waste, wheat bran, plaster and limestone) and C2 (cotton textille mill waste, wheat bran, bean straw, plaster and limestone). A DIC experimental design was used, with nine repetitions for treatment and the production data and biological efficiency were analyzed being used the procedure ANOVAG of the statistical package SAEG. The cotton textille mill waste improvement, as the main ingredient of the substrate, was shown efficient for the production of the mushroom P. sajor-caju, presenting satisfactory values of productivity (0,56 and 0,55 kg/kg substratum) and biological efficiency (55,76 and 55,39%), respectively for C1 and C2. These results showed us that cotton textille mill waste, could be recommended as less onerous alternative of commercial substrate for the species Pleurotus sajor-caju.

    Abstract: Objetivou-se avaliar a degradação ruminal in situ da matéria seca (MS) e a digestibilidade in vitro de suplementos concentrados a base de farinha de batata diversa peletizada com ureia (0, 4, 8 e 12% da MS). Amostras de cada tratamento foram incubadas por 0, 2, 4, 8, 12, 24, 36 e 48 horas no rúmen de quatro ovinos fistulados. Não houve efeito (P 〉 ;0,05) do nível de inclusão de ureia sobre as frações solúvel ("a") e potencialmente degradável ("b") dos péletes, que variaram, respectivamente, de 2,1 a 12,1%, e de 72,9 a 87,5%. Foi observado efeito quadrático (P=0,03) para a taxa de degradação da fração "b", que variou de 4,75 a 7,39% h-1, sendo o valor máximo estimado em 7,4% h-1, obtido quando 5,9% de ureia foram incluídos no pélete. Foram observados efeitos quadráticos (P≤0,02) do nível de inclusão de ureia nos péletes sobre a degradabilidade efetiva (DE) da MS, considerando taxas de passagem no rúmen de 2, 5 e 8% h-1e os valores máximos de DE calculadas sob estas taxas de passagem no rúmen foram estimados com 6,3 a 7,3% de ureia nos péletes. A digestibilidade in vitro da MS dos péletes foi influenciada de forma quadrática (P=0,02) pelo nível de inclusão de ureia, com valor máximo de 96,9%, estimado quando 7,9% de ureia foram incluídos no pélete. A inclusão de 6 a 8% de ureia nos péletes promove incremento na digestibilidade in vitro e na degradabilidade efetiva da matéria seca

    Abstract: A number of research works have shown the inferiority of the carcass and of the meat of cows mainly of cull cows which are led to slaughter very old and/ or with an unsuitable finishing. This work was aimed to establish among the cows slaughtered in the town of Lavras - Mg the most frequent body condition during the period of March to July and to evaluate the relationship existing between body condition and carcass yield and the yield of some cuts of the rear. The survey was conducted in the slaughterhouse of the town of Lavras - MG and divided into two phases, thus comprehended : phase 1 (1st to 31st of March 2001) determined that 53.41% of the total of animals slaughtered in the period were females and that the body condition scores (BCS) more frequent among them were 3, 4 and 5. In phase 2 (15th April to 15th July 2001) were utilized 140 females viz. 42 cows of BCS 3, 59 females of BCS 4 and 39 of BCS 5. In each sore the cows were ranked into three genetic groups: zebu- crossed, Holstein- crossed and crossbred. In the slaughterhouse before slaughter the cows were weighted classified as to body condition and genetic group and photographed for further classification by other referees. The evaluated parameters were: HCY, kidney and pelvic fat weight LEA, PFT and weight of the cuts (striploin, whole rump and tenderloin). The body condition score (BCS) influenced the HCW, PFT kidney and pelvic weight and the weight of the whole rump in the three genetic groups. For the LEA and weight of the tenderloin only the effect of the BCS on the zebu-crossed cows was found, striploin weight was not affected by the BCS. The zebu-crossed cows presented a greater HCY and PFT but the largest LEA was observed among the Holstein cows. The kidney and pelvic fat and the weights of the cuts (striploin, rump and tenderloin) did not range among the genetic groups. From the results obtained, one can conclude that the cows slaughtered in the period presented poor body condition and that this influenced the carcass yield characteristics.

    Abstract: The aim of this work was to evaluate the ability of the Cornell Net Carbohydrate and Protein System (CNCPS) version 5.0 to estimate the dry matter intake (DMI) of grazing lactating Holstein cows, grazing coast-cross pasture supplemented with corn silage and concentrate (3 or 6 kg/cow/day). Six experiments were carried out, with 12 cows each. The cows were fed 17 kg/cow/day of corn ensilage in three experiments. The chemical composition of extrusa samples of forage was determined, obtained using an esophageous fistulated cow. The intake estimates were obtained using 5 g of chromium oxide (Cr2O3) methodology supplied two times a day. Data corresponding to animals (body weight, age, milk yield and composition and racial type), environment (temperature, air relative humidity and management condition) and the feed chemical composition in each experimental period were provided to the program. The DMI values predicted by the CNCPS model were close to those obtained by the chromium oxide methodology.

    Abstract: With the purpose of minimizing the costs of feeding, the use of residues viable to animal nutrition has been searched. "Discarded potato" is the name ascribed to the tuber improper for human consumption, because it does not reach commercialization standards lather in size and quality. The determination of the degradable or not fractions in the rumen is of fundamental importance in the balancing of diets for bovines. So, the in situ degradability technique has been employed to determine the disappearance of nutrients in the rumen as related to the time. Thus, it was aimed to produce and estimate the in situ degradability of the different fractions of elephant grass silage produced with different levels of "discarded potato" meal added to the silage. The experiment was carried out in the Animal Science Department of the Federal University of Lavras. For ensiling, experimental PVC silos fitted with a Bunsen-type valve with a capacity of about 3 kg each were utilized. The treatments consisted of the levels of 0%, 5%, 10%, 15% and 20% of inclusion of "discarded potato" meal into elephant grass. The experimental utilized was the completely randomized design with five treatments and four replicates. This study showed that addition of 15% and 20% of "discarded potato" to elephant grass silage provided better results which characterize a good silage and higher values of in situ ruminal degradability for DM, CP and NDF.
