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","PeriodicalId":49613,"journal":{"name":"Revista Colombiana De Ciencias Pecuarias","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42457871","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}

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)].

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.

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.","PeriodicalId":49613,"journal":{"name":"Revista Colombiana De Ciencias Pecuarias","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67612294","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}

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.","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}
