Abstract: The objective of this study was to evaluate the quality of milk and cheese and sensory analysis of cheese from goats that received a diet with different levels of sorghum silage in the diet. Twenty Anglonubian dairy goats were used, with an average age of 2 years, average live weight of 43.7 kg, distributed in a completely randomized design, with five replications. Moisture (P=0.001), total solids (P=0.001), fat (p=0.001), TDE (P=0.006) and protein (P=0.003) of goat cheese showed a significant difference due to the inclusion of silage from goat cheese. sorghum in the diet. The sensory attributes soft appearance (P<.0001), look (P<.0001), salty taste (P<.0001) and smooth texture (P=0.0430) showed a significant difference depending on the level of sorghum silage added to the diet. of goats. In the PC analysis, it is observed that three main components were needed to represent the variation of 64.84% of the data. PC 1 determined 29% of the data variation and was represented by the attributes with the highest averages: attractive aroma (5.87) and global acceptability (7.74). The inclusion of up to 45% of sorghum silage in the diet of goats increased milk and cheese fat, which favored high scores for the attributes of softness and global acceptance.

O objetivo deste estudo foi caracterizar substratos e avaliar a emergência e a sobrevivência de sementes de milho, bem como o crescimento, massa seca da parte aérea e a massa seca da raiz de plântulas cultivadas com substratos (solo e dejetos de ovinos), alimentados com água com diferentes níveis de sólidos dissolvidos totais (SDT)- 640; 3.188; 5.740 e 8.326mgl. O estudo foi desenvolvido em casa de vegetação no setor de produção de mudas da Embrapa Semiárido em Petrolina-PE. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro tratamentos e dez repetições. Os dados foram analisados por meio de contrastes ortogonais e regressão polinomial. Foi verificado efeito (P<0,05) no índice de velocidade de emergência, sendo estimado por regressão que o melhor substrato deva conter até 1811SDT na água de beber dos animais para essa variedade de milho. No entanto, na biomassa da parte aérea e da raiz, o percentual de sobrevivência e altura das plântulas não sofreram modificações (P>0,05).

The objective of this study was to characterize and to evaluate the emergence and survival of maize seeds, as well as growth, dry mass of shoot and root dry mass of seedlings grown with manure of sheep fed with water with different levels of total dissolved solids (TDS) -640, 3188, 5740 and 8326 mg-1. The study was conducted in the greenhouse industry seedling production at Embrapa Semi-Arid in Petrolina-PE. The experimental design was completely randomize with four treatments and ten replicates. Data were analyzed using orthogonal contrasts and polynomial regression. It was significant (P<0.05) in the rate of emergence estimated by regression that the best substrate should contain until 1811 SDT in drinking water for this variety of corn. However, the biomass of shoot and root, the percentage of survival and seedling height have not been changed (P>0.05).
