21 Background: Nano-vitamins and minerals are used in animal nutrition to improve 22 performance and health of broiler chickens as a potential alternative to antibiotic 23 growth promoters. Objective: To evaluate the effect of several levels of a dietary 24 nano α-tocopherol acetate plus selenium compound (NTS) on growth, intestinal 25 histomorphometry, carcass traits, and immune status of broiler chickens. 26 Methods: A total of 240 one-day-old Ross 308 chickens were randomly divided 27 into four groups, each one containing three pens (n=20 in each pen). Four doses of 28 nano α-tocopherol acetate and SE (0, 5, 7, and 10 mg/kg) were included in the 29 basal diet for 42 days. Results: The final body weight (BW), cumulative body 30 weight gain (BWG), and final feed conversion ratio (FCR) significantly improved 31 when NTS levels were increased (P<0.05). The carcass traits and weight of 32 internal organs enhanced in the groups fed with 7 and 10 mg/kg NTS. With high 33 doses of NTS significantly increased the immune vaccine titers against Newcastle 34 disease (ND), avian influenza (AI) virus, infectious Bursal disease (IBD), and 35 infectious bronchitis (IB). Moreover, dietary addition of NTS improved some 36 intestinal morphometric properties. Conclusion: Thus, NTS (7 and 10 mg/kg) can 37 be added in poultry rations to improve production, carcass characteristics, and 38 immune status of broilers. Further studies are needed to evaluate NTS residues in 39 meat. 40

25 Background: Raising healthy calves is one of the main requirements to ensure profitability in 26 the enterprises, and depends highly on the success in the calf feeding and management 27 programs. Objective: To determine the effects of weaning weight on the growth performance, 28 feed efficiency, behavioral traits as well as feeding cost of Holstein Friesian and Brown Swiss 29 calves. Methods: Sixty-seven newborn dairy calves were allocated into four different weaning 30 weight groups [60 kg (n=18), 65 kg (n=19), 70 kg (n=18) and 75 kg (n=12)]. Body weights and 31 measurements were determined at birth, weaning and 4 months of age. Instantaneous sampling 32 method was utilized to collect the behavioral data. Results: Daily weight gain of Brown Swiss 33 calves between weaning and 4 months of age was significantly higher than Holsteins (p<0.05). 34 Furthermore, daily weight gains of calves weaned at 60 kg body weight was significantly 35 (p<0.05) lower than other three groups in the pre-weaning period. Feed efficiency of Holstein 36 calves was significantly higher than Brown Swiss calves in the periods between birth and 4 37 months of age (p<0.05). Growth in the chest depth of the calves in the group weaned at 60 kg 38 body weight was significantly (p<0.05) lower than other groups. Only drinking behavior was 39 notably (p<0.05) higher in the calves weaned at 75 kg body weight in the pre-weaning period. 40 Conclusions: The results of this study suggest that dairy calves can be weaned at 60 kg body 41 weight without any detrimental effect on their performance and feeding cost for 1 kg weight 42 gain is significantly lower compared to advanced weaning weights. 43

31 Background: Crocodile farming aims to produce high-quality skins from captive 32 crocodilians. Captivity usually exposes the animals to stressful conditions, resulting in 33 increased serum corticosterone (CORT) levels that correlate negatively with those of sex 34 hormones and reproductive success. Objective: To evaluate serum concentrations of CORT 35 and sex hormones and their relationship in farmed Morelet’s crocodiles ( Crocodylus 36 moreletii ), in the non-breeding (NBS) and breeding (BS) seasons. Methods: The study 37 included 59 adult crocodiles (29 females, 30 males). One blood sample was collected in 38 NBS (n = 31) and BS (n = 28) from each crocodile to determine serum concentrations of 39 CORT, estradiol (E 2 ), progesterone (P 4 ), and testosterone (T). Throughout the study, 40 crocodiles were kept in mixed-sex groups and were fed once or twice a week. Results: In 41 females, CORT was higher (p<0.05) in NBS, but had no correlation (p>0.05) with E 2 or P 4 42 in any season. In males, CORT was similar (p>0.05) in NBS and BS, and had no correlation 43 (p>0.5) with T. Conclusion: Levels of CORT had no effect on sex hormones perhaps 44 because CORT was low as a result of farming conditions that did not expose the animals to 45 severe or chronic stress.

Background: Farming of Muscovy ducks ( Cairina moschata ) is an important part of the poultry industry in developed countries. However, the lack of research and improvement programs has led to poor productive outcomes in developing regions where this duck breed is important to procure adequate food security. Objective: To evaluate the effect of improved management conditions and the use of commercial probiotics on the growth performance of Muscovy ducks in a semi-intensive system farm in Colombia. Methods: We recorded the weight gain and feed conversion ratio (FCR) of ducks under three treatments: Backyard management, improved management, and improved management plus probiotic supplementation. Results: The backyard farming system led to poor weight gains (male=2,797 g; female=1,605 g) and less efficient FCR (4.06). Improvement of management conditions led to a better (p<0.05) FCR (3.1) and a greater (p<0.05) weight gain (male=2,888 g; female=1,637 g). The FCR under improved management is comparable to those reported in developed duck farming industries, but the final weight was notably lower than those obtained with selected lines. The use of commercial probiotics led to significant (p<0.05) improvement in weight gain (male=2,930 g; female=1,692 g); however, it also increased the FCR (3.5; p<0.05). Conclusions: The improvement of management conditions enhance the productivity of Muscovy ducks, but further genetic selection processes or use of selected lines is required in developing countries such as Colombia. Further studies are required to assess if probiotic supplementation can lead to improvement in Muscovy ducks farming due to the contrasting effect over the weight gain and FCR.

Background: Weaning is the most stressful event in pig’s life, resulting in postweaning diarrhea and growth retardation. The supplementation of Advanced Digestion Enhancing Protein Plus Technology (ADEPPTTM), which contains iron-binding polypeptides and non-starch polysaccharides, to nursery diets may reduce the occurrence of diarrhea and enhance growth performance of weaning pigs. Objective: To evaluate the effect of ADEPPTTM supplementation on growth performance and fecal score in weaning pigs. Methods: At weaning, a total of 54 weaning pigs (initial body weight: 7.42 ± 0.52 kg) were assigned to 3 treatments in 3 replicates with 6 pigs per pen based on sex, breed, and body weight for a 28-d feeding trial. The pigs were fed corn-soybean meal-based diets containing 0.0, 0.5, and 1.0% of the ADEPPTTM product in 2 phases (d 0-14 and d 15-28 postweaning, respectively). In the first week (d 3-5 postweaning) of the trial, a pig was removed from each pen when diarrhea was observed, housed in a separate pen within treatment, and then treated for 3 days with a 100-ml solution of electrolytes and ADEPPTTM by drenching. Growth performance and fecal score (1=normal to 4=watery diarrhea) were measured. Results: In the feeding trial, there were no significant differences in body weight, average daily gain, and average daily feed intake throughout the overall period. However, a quadratic trend was observed in gain to feed ratio (p=0.09) for d 0-7 postweaning and overall period with increasing ADEPPTTM supplementation levels in which the greatest value was observed in the 0.5% ADEPPTTM level. The fecal score tended to decrease linearly with increasing ADEPPTTM levels during d 0-7 (p=0.11) and 0-14 (p=0.12) postweaning. There was no significant difference on fecal score of diarrheic pigs and average daily gain tended to increase linearly in d 21-28 postweaning (p=0.08) with increasing ADEPPTTM levels. Conclusion: These results indicate that 0.5% ADEPPTTM supplementation has a potential to enhance growth performance of weaning pigs and might be effective to prevent and control postweaning diarrhea.

Conclusion: These results indicate that 0.5% ADEPPTTM supplementation has a potential to enhance growth performance of weaning pigs and might be effective to prevent and control postweaning diarrhea.","PeriodicalId":49613,"journal":{"name":"Revista Colombiana De Ciencias Pecuarias","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47237018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anamnesis: A descriptive series of six cases in dogs with glaucoma are presented, aiming to 26 compare the fibrosis inhibition effect of three pharmacological principles applied during 27 trabeculectomy. Clinical findings: The patients obtained a diagnosis of primary chronic 28 closed-angle glaucoma, refractory to topical medical treatment, with no pupillary light reflex, 29 a negative visual threat eyeblink response, and ocular pain. Therapeutic approach: Two 30 patients received an intraoperative application of bevacizumab, two received 5-fluorouracil, 31 and two, mitomycin C. The intraocular pressure (IOP) and the filtering ampoule were observed 32 on days 1, 7, 30, 60, and 90 of postsurgical evolution. Conclusion: According to our results, 33 the bevacizumab manages to regulate the IOP under 25 mmHg and constitutes the drug of 34 potential choice in dogs with primary closed-angle glaucoma, without a previous positive 35 response to topical therapy and subjected to TEC, when compared with 5-fluorouracil and 36 MMC regarding the inhibition effects of fibrosis. 37
