Post-mortem characterization of Dorper x Santa Inês lambs fed diets containing alternative foods

The objective of this study was to evaluate the post-mortem characteristics of lambs fed diets containing alternative foods. Twenty lambs, castrated Dorper x Santa Inês males, aged approximately 90 days and with mean weight of 20 kg were used. Experimental diets were composed of ground corn, soybean meal, mineral supplement, urea and Tifton-85 hay (forage). In addition to these ingredients, cottonseed, sunflower meal and castor bean cake were used as alternative foods in the proportions of 10, 8 and 8% of %DM, respectively. The experiment lasted 106 days, with 14 days for adaptation and 92 days for evaluation and data collection. At the end of the confinement period, the lambs were slaughtered, and the carcasses kept under cooling for a period of 24 hours. The measurements of pH, carcass temperature (internal and external) were measured in the Longissimus lumborum muscle, as well as the temperature and relative humidity of the cold chamber were measured. Muscle pH was altered as a function of diet and reached a value of 5.78 (lower pH) when lambs received the diet with castor bean cake. The internal carcass temperature was higher in the lambs that received the diet containing cottonseed (19.98°C), sunflower meal (19.71°C) and castor bean cake (19.87°C). The alternative foods can be used as ingredients in the formulation of diets for Dorper x Santa Inês lamb, for promoting the proper development of the post-mortem process, characteristic of good quality sheep meat.The objective of this study was to evaluate the post-mortem characteristics of lambs fed diets containing alternative foods.

In addition to these ingredients, cottonseed, sunflower meal, and castor bean cake were used as alternative foods in the proportions of 10, 8, and 8% of %DM, respectively. The experimental design was completely randomized with four treatments (diets) and five replicates (lambs). The experiment lasted 106 days, with 14 days for adaptation and 92 days for evaluation and data collection. At the end of the confinement period, the lambs were slaughtered and the carcasses kept under cooling for a period of 24 hours. The pH and carcass temperature (internal and external) were measured in the Longissimus lumborum muscle. The temperature and relative humidity of the cold chamber were obtained. Muscle pH was altered as a function of diet and reached a value of 5.78 (lower pH) when lambs received the diet with castor bean cake. The internal carcass temperature was higher in the lambs that received the diet containing cottonseed (19.98°C), sunflower meal (19.71°C), and castor bean cake (19.87°C). The muscle pH correlated in a moderate and positive way with the temperature of the carcass (internal and external) and of the cold chamber, in the different diets evaluated. There was positive correlation with values ranging from moderate to high between humidity of the cold chamber and the temperature (internal and external of the carcass; and of the cold chamber). The alternative foods can be used as ingredients in the formulation of diets for Dorper x Santa Inês lambs, as it promoted the proper development of the post-mortem process, which is characteristic of good quality sheep meat

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Silagens de capim elefante com diferentes proporções de casca desidratada de maracujá em dietas de cordeiros Santa Inês Elephant grass silage with different proportion of dehydrated peel of passion fruit in diets Santa Inês lambs

Avaliou-se o consumo, a digestibilidade, e o desempenho de cordeiros alimentados com silagem de capim elefante que continha diferentes níveis de inclusão de casca de maracujá desidratada (0; 10; 20 e 30%) na matéria natural do capim elefante, em delineamento inteiramente casualizado. O capim elefante foi cortado com 60 dias de idade, picado e ensilado em tonéis juntamente com as proporções de casca de maracujá desidratada, conforme cada tratamento. Após 30 dias os silos foram abertos, quando se deu início ao experimento. Observou-se que a inclusão do resíduo influenciou o consumo e a digestibilidade de alguns nutrientes. Houve efeito para o ganho de peso médio diário e ganho total dos cordeiros, com elevação de 2,42% do ganho médio diário para cada 1% de casca de maracujá desidratada adicionada. A conversão alimentar apresentou efeito linear decrescente (8,9; 9,2; 8,6 e 7,2), respectivamente, entre os tratamentos, o que permitiu concluir que a casca de maracujá desidratada pode ser utilizada em até 30% de inclusão ao capim elefante.The consumption, digestibility, and performance was evaluated of lambs fed silage elephant grass containing different inclusion levels of passion fruit peel dried (0, 10, 20 and 30%) in natural matter of elephant grass, in a randomized completely randomized design with four replications. The elephant grass was cut at 60 days old, chopped and ensiled in barrels along with the proportions of dried passion fruit peel as each treatment. After 30 days, the silos were opened, beginning the experiment. It was observed that the inclusion of the residual affect intake and digestibility of certain nutrients. Effect was observed for average daily weight gain and total gain of the lambs, and for every 1% of passion fruit peel added dried rose 2.42% for Average daily gain. The feed showed decreasing linear effect (8.9, 9.2, 8.6 and 7.2), respectively, between treatments, the report concludes that the passion fruit peel dried can be used in up to 30% inclusion elephant grass

Carcass characteristics of sheep fed diets with slow-release urea replacing conventional urea

This study aimed to evaluate the effects of adding slow-release urea to replace conventional urea in the diet on carcass characteristics of feedlot sheep. We used 20 Santa Ines x SRD rams, with average body weight of 21.1±1.2 kg and average age of 120 days, distributed in a completely randomized design with 5 treatments. The replacement levels used as treatments were 0, 20, 40, 60, and 80%, composing diets of about 12% crude protein, with 50 % Tifton-85 hay and 50% concentrate. There was no influence of slow release urea on weight at slaughter (35.17 kg), and on hot (16.75 kg) and cold (16.24 kg) carcass weight, but the yield of these carcasses showed quadratic trend, revealing lower percentages at 48.5 and 47.63% replacement levels, respectively. The weights and yields of cuts did not change, except for the posterior arm, whose values showed a cubic trend. Objective measures of carcass, loin eye area, and subjective evaluations of conformation, finishing and marbling of carcasses were not affected. The subcutaneous fat thickness decreased linearly (4.25 to 2.48 mm). The inclusion of slow release urea in the diet changes the yield and reduces subcutaneous fat, however, it does not influence other carcass characteristics
