RESUMO - O objetivo deste trabalho foi avaliar a composição bromatológica da forragem produzida a partir da parte aérea de plantas remanescentes da colheita de minimilho, em diferentes épocas de semeadura e idades de corte das plantas. O experimento foi realizado na fazenda experimental da UNIMONTES, localizada no município de Janaúba – MG. Os tratamentos foram dispostos em esquema fatorial 3 x 5, envolvendo três épocas de semeadura (agosto, dezembro e abril) e cinco idades de corte das plantas remanescentes (0, 8, 16, 24 e 32 dia após a colheita das espigas). O delineamento experimental utilizado foi de blocos ao acaso com quatro repetições. As parcelas foram formadas por quatro fileiras de milho, espaçadas de 0,9 m entre si, com 5,0 m de comprimento. As avaliações foram realizadas utilizando-se as duas fileiras centrais, desprezando-se 0,5 m de cada extremidade. A colheita das miniespigas foi realizada manualmente 2 dias após a emissão dos estilo-estígmas nas três épocas de plantio. As características avaliadas na forragem produzida a partir da parte aérea das plantas remanescentes foram o teor de proteína bruta, extrato etéreo, cinzas, matéria seca, matéria orgânica, fibra em detergente ácido, fibra em detergente neutro, lignina, hemicelulose, celulose e carboidratos não fibrosos. Os resultados obtidos permitiram concluir que há um incremento, para lavouras semeadas em agosto e em abril, nos valores de matéria seca, matéria orgânica e FDN e uma redução nos valores de cinzas e FDA das plantas remanescentes com o passar do tempo.Palavras chave: forragem, milhos especiais, Zea mays.CHEMICAL ANALYSIS OF BABY CORN IN DIFFERENT TIMES OF SOWING AND HARVESTING AGES OF REMAINING PLANTSABSTRACT - The aim of this study was to evaluate the chemical composition of baby corn crops at different times of sowing and harvesting ages of remaining plants in the northern region of Minas Gerais.

ABSTRACT Knowledge of herbicides sorption by colloids predicts its movement in the soil profile and its effectiveness in controlling weeds and crops poisoning when directly applied to the soil. This knowledge becomes even more important for herbicides which have long persistence in the soil. In this research, clomazone sorption was estimated by the biological method in Brazilian soil samples with different physical and chemical characteristics, cultivated with sugarcane crops. As an indicator of the presence of clomazone in the soil, Sorghum bicolor was used. The data relating to assessments of poisoning and accumulation of dry matter of the plants were subjected to multivariate analysis of similarity among variables. After that, clomazone doses that caused 50% of intoxication in sorghum plants grown (C50) as well as sorption ratio (SR) of the herbicide in different soil types were estimated. There was similarity greater than 80% for data regarding the percentage of intoxication and accumulated dry matter, with the option to use only those related to the first variable. RS and C50 were higher in Organosol and lower in red-yellow Latosol with and without changing the pH. It was concluded that the clomazone dose to be recommended must be differentiated for different soils, since the value of clomazone sorption in the soil is dependent on its attributes, and the organic matter content is of the utmost importance.

SUMMARY It was evaluated the effect of feed supplementation at 0.4; 0.8 and 1.2% of body weight (BW) on intake and digestibility of crossbred goats finished on caatinga, in relation to crossbred goats not supplemented (0.0% of BW). Thirty-two crossbred, Anglo-Nubian goats were used, eight months old and with body weight of 18 ± 2.5 kg, organised into randomised blocks, which were kept on 37 hectares of caatinga from 7 h to 16 h. Intake of dry matter, organic matter, crude protein, ether extract, neutral and acid detergent fibre, total carbohydrates and total digestible nutrients was influenced (P<0.05) by the levels of feed supplementation, with linear increases of 202.31; 179.42; 25.05; 11.83; 35.79; 12.27; 142.63 and 166.79 g animal-1 day-1 respectively. There was a substitution effect (P<0.05) on dry matter intake when using feed supplementation at 0.7% BW. Feed supplementation resulted in positive linear effect (P<0.05) for digestibility of dry matter, organic matter, crude protein, ether extract, total carbohydrates, total digestible-nutrient content and digestible energy, with an increase of 17.15; 16.64; 19.07; 44.74; 15.15 and 17.56% for dry matter, and 0.69 Mcal kg-1 of dry matter respectively. Final body weight, total gain and average daily gain, showed a linear increase (P<.005) of 2.60, 3.09 and 0.036 kg per percentage point of each additional level of supplement. Feed supplementation increases the intake and digestibility of total dry matter and nutrients, a fact that makes greater performance possible, and recommends use up to a level of 0.7% BW to avoid any substitution effect.

The quality and palatibility of silage and hay complete ration based on organic primer garbage in peranakan etawah (PE) poadABSTRACT. This research was conducted to study the quality and palatability of silage and hay complete ration based on organic primer garbage in nine heads of Peranakan Etawah (PE) Goat. The quality of silage and hay was evaluated By measuring pH, total number of lactic acid Bacteria (LAB), palatability, dry matter (DM) and organic matter (OM) aroma and color of silage. Nine heads of peranakan etawah were grouped based on their lactation periode and randomly assigned to one of tree dietary treatments. The treatments were (1) Control rations; (2) silage complete ration (SRK); and (3) Hay complete ration (HRK). The results indicated that the silage had PH 4.15 and total number of LAB was 2.4 x 10 cfu/g of silage. Dry matter and organic matter digestibility of SRK were better than those of HRK. The palatability of SRK was higher than HRK but less than control. Storage of SRK for did not change dry matter and organic matter content. Organoleptic analysis indicated that texture and color of HRK were changed at after storage, while SRK was still constant. It is concluded that silage composed of organic primer garbage has high quality in terms of physical, chemical and microbial characteristics, prolong storage.

Altogether 19 fodder climbers were collected with local information for their quality, feeding season and preference by livestock from Sunsari district, Nepal. Fodder climbers were distributed under 15 angiospermic families. Among them, 6 climber species were analyzed for dry matter, crude protein, ether extract, crude fibre, N-free extract, total ash and mineral contents (K, Ca, and P). Dry matter content ranged from 24.12 to 45.43%. Crude protein content showed slight variation. Ether extract ranged from 2.13- 4.23%, while Crude fiber content ranged between 18.62 and 22.52%. N-free extract showed narrow variation in the content while Total ash content exhibited a wide variation ranging from 5.67 to 11.52%. Among the minerals, Phosphorus showed distinct variation in the content from 0.19 to 0.46%. Fodder quality assessed by local people was compared with the result of chemical composition. On the basis of local information and chemical composition, Hedera nepalensis and Hedyotis scandens were considered as very good fodder climbers.

Steers of 252 kg initial mean liveweight were fed 0.44 kg of hay dry matter (DM)/head day-1 plus five rates of whole oats, crushed wheat or whole wheat, with the crushed wheat rations providing 0.7 to 1.3 times the estimated energy for maintenance. All-grain rations at these energy levels had been attempted, but resulted in digestive upset, and were abandoned. The results obtained, listed in the order of the above grains, were : 1 ) grain in ration to maintain liveweight: 1.31, 1.41 and 1.85 kg DMIhead day-1 ; 2) additional grain for each 10 kg improvement in liveweight over I2 weeks: 434,466 and 61 3 g DMIhead day-1 ; 3) mean digestible organic matter content (DOM) of rations, tested at the highest and lowest rates of grain : 69.4, 84.5 and 68.3%. The DOM of the oat rations declined by 8.1 units from the lowest to highest rate of grain. The relative liveweight change on oats could not be explained by the DOMs. Nevertheless, the results suggest, for similar conditions to those applying in our experiment, that: 1) whole oats may be at least as good a feed as crushed wheat, and both will be much better than whole wheat; 2) the feed requirement for maintenance may be about 20% less than standard recommendations; 3) even a little hay in the ration, compared with grain only, may greatly reduce the likelihood of digestive upset

Twenty grass populations were evaluated for dry matter yield, N content, P content, organic matter content, organic matter digestibility and winterhardiness. Of these populations, Agropyron intermedium was most suitable for a hay crop on a well-drained irrigated soil. Agropyron trichophorum, Bromus inermis, and Phalaris arundinacea were lower-yielding alternatives that had a satisfactory N content and good digestibility. Elymus angustus shows promise as an irrigated hay crop and should be evaluated further. The usefulness of the following populations was limited by one or more of these factors: low yield (Y), low N content (N), low digestibility (D) and lack of winterhardiness (W): Dactylis glomerata ’Kay’ (Y,N,D), Dactylis glomerata ’Chinook’ (Y,N,W), Elymus sibiricus (Y), Festuca arundinacea ’Kenmont’ (Y,N,W), Festuca elatior ’Trader’ (Y,N), Phleum pratense (Y,N,D), Poa ampla ’Sherman’ (N,D), Poa bulbosa cv. P4874 (Y,N,D), and Poa pratensis (Y,N,D).

A trial involving a 2x2 factorial design was conducted to evaluate the effect of corn silage hybrids and concentrate levels (25 and 50%) on intake and digestibility of nutrients, ruminal characteristics and microbial efficiency in steers. Four ruminal and abomasal cannulated steers (512±25kg of birth weight), were used in a 4×4 Latin square design. Treatments consisted of 75% silage A + 25% concentrate; 50% silage A + 50% concentrate; 75% silage B + 25% concentrate; and 50% silage B + 50% concentrate on dry matter (DM) basis. There were no differences in the intakes of DM, organic matter (OM), crude protein, and ether extract. The intake of non fiber carbohydrates and total digestible nutrients were positively affected by concentrate levels. The digestibility of DM and OM were also positively affected by concentrate levels. There were no effects of treatments on ruminal pH values, ruminal ammonia-N, and microbial efficiency.
