This book was released on 2011-09-01 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lactation trial was conducted in cross bred cows for 120 days. The parameters were milk yield, milk composition, body weight, nutrient utilization and microbial protein synthesis in crossbred lactating cows after feeding garlic oil (T1) and garlic-oregano oil combination (T2). No changes were observed in milk yield and milk composition except increase in fat percentage at last fortnight. Both blood urea N and milk urea N were decreased in treatment group. As the sensory evaluation scores were of 'good' category, the milk of all the groups was fit for human consumption. EO did not make any significant impact on DM intake. The statistical analysis of data of DM and OM digestibility revealed that the differences between the groups were not significant (P0.05). Though allantoin and total PD concentration were numerically much higher in T1 than control, the variation did not differ significantly as standard error was much higher.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A literature review and a research study were performed to examine cobalt and vitamin B12 nutrition in dairy cattle. The literature review revealed that cobalt supplementation increases ruminal vitamin B12 synthesis and the current cobalt requirement stated for dairy cattle (0.11 mg/kg DM) is inadequate based on beef cattle research showing improvements in performance and vitamin B12 status at 0.25 mg Co/kg DM. Cobalt supplementation for dairy cattle above requirements has had varied lactation performance results with little improvement of vitamin B12 status measures. Dairy cattle given vitamin B12 injections have shown improvements in milk production when fed folic acid and rumen-protected methionine. The objective of this study was to determine lactation performance and metabolism parameters of dairy cows fed different levels and sources (inorganic and organic) of cobalt or given weekly vitamin B12 injections. Forty-five primi- and multiparous cows starting at 60 d before parturition were assigned to 1 of 5 treatments: 1) no supplemental Co (Control), 2) 25 mg/d supplemental Co from cobalt carbonate (CoCarb), 3) 25 mg/d supplemental Co from cobalt glucoheptonate (LCoGH), 4) 75 mg/d supplemental Co from cobalt glucoheptonate (HCoGH), and 5) Control diet plus weekly 10 mg vitamin B12 injections (IB12). Cows remained on their respective treatment until 150 DIM. Cobalt (mg/kg DM) in the lactating diets was 1.0, 1.9, 2.3, and 5.1 for Control/IB12, CoCarb, LCoGH, and HCoGH, respectively. Dry matter intake, body weight, and body condition score were unaffected by treatment. LCoGH tended to have greater milk yield than CoCarb, but Control had similar milk yields to the mean of LCoGH and HCoGH. Treatments did not influence plasma or liver measures of energy metabolism. Vitamin B12 injections increased plasma, liver, and milk vitamin B12 concentrations. Cobalt supplementation did not affect plasma vitamin B12 concentration; but increased milk vitamin B12 concentrations throughout lactation and liver vitamin B12 concentration at calving. Folate status of cows in the study was low and possibly limited the effect of improved vitamin B12 status on lactation performance. Overall, cobalt supplementation or vitamin B12 injections improved certain measures of vitamin B12 status, but not lactation performance compared to Control.

This book was released on 2010 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential oils, due to their antimicrobial effects, have the potential to alter ruminal fermentation patterns through the inhibition of specific microorganisms. Alterations to ruminal fermentation could increase the efficiency of energy and nitrogen metabolism. In this study, over 60 essential oils native to the United States were analyzed in vitro using a batch culture incubation. From these results, one plant material, oregano, was then selected to be examined in the in vivo portion of the study. Oregano was supplemented at 500 g/cow/day to 8 multiparous Holstein cows, 4 of which were rumen cannulated, in a 4x4 Latin square design. The trial was a switch-over design with periods of 21 days each, for 14 days of adaptation and 7 days of sampling. Effects on milk yield, milk composition, ruminal fermentation, urinary nitrogen losses, urinary and fecal emissions, and total tract digestibility of nutrients were measured. In vitro incubations demonstrated that ruminal methane production was significantly reduced and NDF digestibility was improved for the plant material Origanum vulgare, therefore it was selected for in vivo experimentation. In the vivo experiment, Origanum vulgare significantly decreased ruminal methane production, illustrating the potential for improved energy efficiency. However, ammonia production within the rumen was significantly increased, suggesting that oregano supplementation may alter the metabolism of some bacteria in the rumen such that their capture of nitrogen is reduced.
