The experiments reported in this research paper address the effects of replacing ground corn (GC) with full-fat corn germ (FFCG) on nutrient intake and digestibility, nitrogen utilization efficiency, performance, and predicted methane production in dairy cows fed cactus cladodes and sugarcane. We hypothesized that the inclusion of FFCG in the diet would not alter the performance of lactating cows but would reduce the predicted methane production in vivo. Ten multiparous Holstein cows at 90 ± 10 d of lactation and yielding 24.2 ± 3.5 kg milk/d were assigned to dietary treatments consisting of different levels of replacement of GC by FFCG (0; 25; 50; 75 and 100% of diet dry matter) in a replicated 5 × 5 Latin square design with 21-d periods. Methane production was predicted using an automated gas in vitro production system. Except for ether extract intake, which increased, the intake of all nutrients decreased linearly with the replacement of GC by FFCG. The digestibility of dry matter, organic matter and neutral detergent fiber reduced, whereas the digestibility of ether extract increased linearly with FFCG. There were no changes in the digestibility of crude protein. The nitrogen intake and daily excretion in urine and feces decreased, while nitrogen use efficiency increased linearly. There was no significant effect of diets on nitrogen balance or microbial protein synthesis and efficiency. The yield of protein, lactose and total solids in milk showed a quadratic behavior. On the other hand, milk fat yield and energy-corrected milk yield decreased linearly with the replacement of GC by FFCG. No effect on pH or ammonia nitrogen was observed. The production of methane (CH4, g/kg DM) and total CH4 (g/d), and CH4 intensity decreased linearly with the replacement of GC by FFCG. In conclusion, FFCG has been shown to be an effective source of fat to reduce methane production in dairy cows, partially supporting our initial hypothesis. However, as it decreases milk fat production, it is not recommended to replace more than 50% of GC by FFCG for lactating cows fed cactus cladodes and sugarcane.

O cachorro-do-mato (Cerdocyon thous) pertence à família Canidae, encontra-se amplamente distribuído pela América do Sul. Devido à escassez literária a respeito da morfologia desta espécie objetivamos colaborar com o conhecimento da anatomia do arco aórtico e seus ramos colaterais. Foram estudados quatro animais, sendo 2 machos e 2 fêmeas oriundos da Mina de Bauxita, Paragominas, Pará, Brasil/Terra Ltda, sob autorização da SEMA-PA nº 455/2009, que morreram por causas naturais. O sistema arterial foi preenchido com látex corado em vermelho e fixado em solução aquosa de formoldeído 10%. O arco aórtico de Cerdocyon thous apresentou em sua origem apenas dois vasos, o tronco braquiocefálico e a artéria subclávia esquerda. Do tronco braquiocefálico originou-se o tronco bicarotídeo, que se bifurcou nas artérias carótidas comum direita e esquerda, e artéria subclávia direita. Das artérias subclávias ocorreu a formação do tronco costocervical, artéria vertebral, artéria torácica interna, artéria cervical superficial e ao atingir o espaço axilar passa a ser chamada de artéria axilar em ambos os antímeros. Concluímos que o arco aórtico de Cerdocyon thous é similar ao de outros animais domésticos com relação ao número de ramificações em sua origem. |
