Abstract: This study aimed to evaluate the influence of the substitution of soybean meal (SM) by detoxified castor cake (DCC) by two alkaline products on intake, performance and on the growth curve of goat?s kids. 24 were used, Saanen goats (n=12) and Anglo Nubian (n=12), with initial body weight of 16.2±0.67 kg, initial age of 3 months and confined during the growth phase. The treatments consisted of three diets: a standard diet formulated with a traditional protein source, the soybean meal (SM); and test diets, which consisted of a protein source alternative, differing detoxification processes, on the basis of calcium hydroxide (Ca(OH)2) or sodium hydroxide (NaOH). The animals were distributed in a completely randomized design, in factorial 3 x 2 (diet SM, Ca(OH)2 DCC and NaOH DCC x Saanen and Anglo Nubian) totaling six sessions with four replicates each. The experimental period lasted 270 days. The non-linear models used were the Gompertz and Logistic. There was no effect (P < 0.05) of diets on the intake of nutrients, but there was no effect (P > 0.05) of breeds and interaction between both factors. The intake of DM during the phase of growth was greater for the goats fed with SM. There was no effect (P>0.05) of diets nor of the breeds in the ADG. Feed conversion was influenced (P < 0.05) by the diets, in which the goats fed diets with DCC presented better feed conversion. It has been observed that both models had good adjustments, with values numerically superior to 90%, however, the logistic model showed higher R2 and, at the same time, asymptotic index (AI). Despite the ADG be equal, the breeds presented absolute growth rate (AGR) vary over time, where the Saanen goats reached the peak first 3378Semina: Ciências Agrárias, Londrina, v. 41, n. 6, suplemento 2, p. 3377-3390, 2020Araújo, R. A. et al.(181 days), with AGR of 0.14 kg day-1. However, even the goats Anglo Nubian reaching the highest peak late, the AGR was higher, around 0.16 kg day-1 higher than the Saanen. Both castor cake has the potential to replace the SM on a diet of goat?s kids during the growth phase. The mathematical model of Logistics estimates more accurately the growth of Saanen goats and Anglo Nubian, being that the rate of absolute growth is greatest in goats Anglo Nubian. [Curva de crescimento e desempenho de cabras leiteiras alimentadas com torta de mamona destoxificada por diferentes soluções alcalinas]. Resumo: Objetivou-se avaliar a influência da substituição do farelo de soja (FS) pela torta de mamona destoxificada (TMD) por dois produtos alcalinos sobre o consumo, desempenho e na curva de crescimento de cabritas de aptidão leiteira. Foram utilizadas 24 cabras, Saanen (n=12) e Anglo Nubiana (n=12), com peso corporal inicial de 16,2±0,67 kg, idade inicial de 3 meses e confinadas durante a fase de crescimento. Os tratamentos consistiram de três dietas: dieta padrão formulada com uma fonte proteica tradicional, o farelo de soja (FS); e dietas testes, que consistiram de uma fonte proteica alternativa, diferindo os processos de destoxificação, à base de hidróxido de cálcio (Ca (OH)2) ou hidróxido de sódio (NaOH). Os animais foram distribuídos em delineamento inteiramente casualizado, em esquema fatorial 3 x 2 (dieta FS, TMD Ca(OH)2 e TMD NaOH x raça Saanen e Anglo Nubiana) perfazendo seis sessões com quatro repetições cada. O período experimental durou 270 dias. Os modelos não-lineares utilizados foram os de Gompertz e Logístico. Houve efeito (P < 0,05) das dietas sobre o consumo dos nutrientes, porém não houve efeito (P > 0,05) das raças e interação entre ambos os fatores. O consumo de MS durante a fase de crescimento foi maior para as cabras alimentadas com FS. Não houve efeito (P > 0,05) das dietas nem das raças no GMD. A conversão alimentar foi influenciada (P < 0,05) pelas dietas, em que as cabras que consumiram as dietas com TMD apresentaram melhor conversão alimentar. Observou-se que ambos os modelos tiveram bons ajustes, com valores numericamente superiores a 90%, contudo, o modelo Logístico apresentou maior R2 e, ao mesmo tempo, índice assintótico (IA). Apesar do GMD ser igual, as raças apresentaram taxa de crescimento absoluto (TCA) diferenciado ao longo do tempo, onde as cabras Saanen atingiram o pico primeiro (181 dias), com TCA de 0,14 kg dia-1. Porém, mesmo as cabras Anglo Nubianas atingindo o pico mais tardiamente, a TCA foi maior, cerca de 0,16 kg dia-1 superior às Saanen. Ambas as tortas tem potencial de substituir o FS em dieta de cabritas de aptidão leiteira durante a fase de crescimento. O modelo matemático Logístico estima de forma mais precisa o crescimento de cabras Saanen e Anglo Nubiana, sendo que a taxa de crescimento absoluto é maior em cabras Anglo Nubianas.

Aim: To avoid the limitations of 16S rRNA-based phylogenetic analysis for Paenibacillus species, the usefulness of the RNA polymerase beta-subunit encoding gene (rpoB) was investigated as an alternative to the 16S rRNA gene for taxonomic studies. Methods and Results: Partial rpoB sequences were generated for the type strains of eight nitrogen-fixing Paenibacillus species. The presence of only one copy of rpoB in the genome of P. graminis strain RSA19T was demonstrated by denaturing gradient gel electrophoresis and hybridization assays. A comparative analysis of the sequences of the 16S rRNA and rpoB genes was performed and the eight species showed between 91·6-99·1% (16S rRNA) and 77·9-97·3% (rpoB) similarity, allowing a more accurate discrimination between the different species using the rpoB gene. Finally, 24 isolates from the rhizosphere of different cultivars of maize previously identified as Paenibacillus spp. were assigned correctly to one of the nitrogen-fixing species. Conclusions, Significance and Impact of the Study: The data obtained in this study indicate that rpoB is a powerful identification tool, which can be used for the correct discrimination of the nitrogen-fixing species of agricultural and industrial importance within the genus Paenibacillus. |
