The cattle were fed a common 12% CP finishing feedlot diet for the entire 90 days experimental period. Blood samples were collected and live-weights recorded at the start of the experiment and then fortnightly thereafter until end of experiment. There were no differences (>P0.05) between all the treatments, however, numerically, Angus showed lowest live-weight gains of 107.9±8.6 kg while Sussex had the largest live-weight gains of 129.7±8.6 kg.

Cattle injected with 7.5 ml BF had the highest live-weight gains of 130.4±8.8 kg implying that doses of BF below 7.5 ml had minimal or no effect. Similarly, cattle that received 7.5 ml Biopro cholesterol had numerically highest blood cholesterol concentrations of 2.12 mmol/L. The BCR treated cattle had cholesterol concentrations numerically greater than those of the control animals.

The samples were collected in vials containing Bronopol (2-bromo-2- nitropropane-1,3-diol), packaged and transported in thermal boxes with ice, and sent for analysis to the laboratory clinica do leite-ESALQ – USP, for total bacterial count (TBC), somatic cell count (SCC), and milk composition in relation to fat, protein, lactose, total solids (TS), dry degreased extract (DDE) contents. The patterns of chemical composition of milk, TBC and SCC observed were within the limits established by regulatory instruction number 51 in all samples, demonstrating that producers adopted hygienic measures for obtaining and conserving the milk, thus ensuring ITS quality.

In this study, feeding trials of broilers were carried out over a period of six weeks to assess the optimal inclusion level of triticale grain in raw and pelleted form in broiler diet as a substitute for maize. The study also involved evaluation of effects of feeding thermal treated (pelleted) diet on performance of broilers. Ten triticale based diets were prepared and incorporated in five inclusion levels of 0, 15, 30, 45 and 60% in raw and pelleted form. The diets were assigned to the experimental units in a factorial arrangement in a completely randomized design. The results of this study showed that inclusion of triticale in broiler diet in either raw or pelleted form significantly improved feed intake (FI) and body weight gain (BWG) (P 0.05). Thermal treatment of the triticale through pelleting reduced FI and BWG (P 0.05). Inclusion level improved FI, BWG and reduced PER significantly (P 0.05). There was positive interaction between pelleting and level of inclusion in BWG (P<0.05) at 30% inclusion level in raw form of triticale. The interaction was negative for the same in pelleted form. It can be concluded from the findings of this study that triticale grain may be used as an alternative feed ingredient in broiler diets in raw or pelleted form without causing any detrimental effect on the performance of the birds. Pelleted triticale based diet may not improve performance in broiler chicken.","PeriodicalId":372944,"journal":{"name":"Journal of Animal Science Advances","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123631457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cows were divided in three groups: Control, P24 and P36.

Starting from the ninth day of the cycle, all cows received eight decreasing doses of FSH and two doses of Dcloprostenol together with the two last doses of FSH. Treatments P24 and P36 had the progesterone device removed 24 and 36 hours after the first application of D-cloprostenol, respectively. All cows received lecireline in the thirteenth day, with the inseminations accomplished 12 and 24 hours later. There was no difference (P > 0.05) for superestimulatory response among treatments. The number of total structures was greater (P < 0.05) in P24 than in the Control and the number of viable structures was greater (P < 0.05) in both P24 and P36 than in the Control.

Currently, the world is facing a number of challenges, of which climate change is a priority area. Climate change affects livestock health through several pathways involving both direct and indirect effect. The direct effects being most likely pronounced for diseases that are vector- borne, soil associated, water or flood associated, rodent associated, or air temperature/humidity associated and sensitive to climate. Furthermore, Climate change influences the emergence and proliferation of disease hosts or vectors and pathogens and their breeding, development and disease transmission. Consequently, it affects distributions and host–parasite relationships and its assemblages to new areas. Climate factors also influences habitat suitability, distribution, and abundance; intensity and temporal pattern of vector activity. Pathogens and parasites that are sensitive to moist or dry conditions may be affected by changes to precipitation and soil moisture. Higher temperatures resulting from climate change may increase the rate of development of certain pathogens or parasites that have one or more life cycle stages outside their animal host. This may shorten generation times and, possibly, increase the total number of generations per year, leading to higher pathogen/ parasite population sizes. Mammalian cellular immunity can be suppressed following heightened exposure to ultraviolet. In particular, there is depression of the number of T helper 1 lymphocytes, the cells involved in the immune response to intracellular pathogens. Therefore, successful adaptations may be shown as better way of coping with the negative consequences of climate change on livestock health.","PeriodicalId":372944,"journal":{"name":"Journal of Animal Science Advances","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128949006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relevant fungal species in silos were P. paneum and P. roqueforti (18.2 % and 14.5 % of total isolates, respectively). The proportion between the two species varied significantly from 2006 to 2007 (P<0.05) depending on the type of forage crop. The prevalence of P. paneum in Belgium compared to results in other countries is of major importance due to the mycotoxigenic capacity of this species. Information on numerous aspects of silage making process and silo management showed that neither the crop rotation, the date and weather at harvest, the use of additives, the feeding rate, the type and dimension of silo, the covering used nor the forage chopping length at ensiling could be significantly correlated to the fungal species composition isolated in farm silages. There were also no significant relationships between the chemo-fermentative parameters tested (dry matter, pH, NH3 content, concentration of lactic, acetic and butyric acids) and the fungal species composition in silages. The prevalent fungi were tolerant of the wide ranges of conditions found in the farm silages with year-to-year variations.","PeriodicalId":372944,"journal":{"name":"Journal of Animal Science Advances","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129191003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
