“…According to the current findings, Gln supplementation (Experiment 1) led to overall improvement in intestinal morphology, including VH, CD and VCR, until 14 days old. In partial agreement with these findings, Nassiri Moghaddam & Alizadeh-Ghamsari (2013) reported the beneficial influence of 1% or 1.5% Gln supplementation of diet on increases in VH and villus surface area of the duodenum and jejunum of 21 and 42-day-old broilers. Benefits from Gln supplementation on small intestine morphology of chicks were observed by Khempaka et al (2011).…”

Two experiments were conducted to investigate the effects of fortification of the pre-starter diet with glutamine in post-hatch broiler chicks. In the first experiment, male chicks were used to study the impact of glutamine supplementation at three levels (0%, 1% and 2%) on performance, apparent faecal digestibility (AFD) and ileal digestibility (AID) of amino acids (AAs), as well as intestinal morphometric parameters from 0 to 14 days old. The best performance was obtained at 1% supplementation. Average daily feed intake and feed conversion ratio (FCR) were affected by treatments. Supplementing diets with glutamine resulted in increase of digestibility values for arginine (Arg), lysine (Lys), isoleucine (Ile) and valine (Val). Glutaminesupplemented diets led to higher villus height (VH) and shallower crypt depth (CD) in the jejunum and ileum. A second experiment was performed to investigate whether the form of glutamine could affect performance and morphometric parameters in newly hatched chickens. A control diet was prepared, based on casein as the sole source of protein-bound AAs. Three diets based on synthetic AAs were used to obtain nutrient values of the control diet, which were supplemented with a synthetic form of glutamine, glutamic acid and a 50 : 50 ratio of glutamine : glutamic acid. Chickens fed the control diet presented higher average daily weight gain and better FCR. None of the AID coefficients of amino acids were influenced by the dietary treatments, except glutamic acid and aspartic acid, which were decreased in chicks fed synthetic AAs. In conclusion, 1% glutamine supplementation improved performance, morphometric parameters and AID and AFD values of cationic AAs. The form in which dietary glutamine was provided could affect performance. ______________________________________________________________________________________

“…In stressful conditions with high ambient temperature, Jazideh et al [7] reported that dietary supplementation of 0.5% Gln, caused a longer duodenum and jejunum VH and higher BWG. Nassiri Moghaddam and Alizadeh Ghamsari [21] observed that 1.0% and 1.5% dietary Gln supplementation increased the duodenum and jejunum VH, VW, and villus surface area of broiler chickens at days 21 and 42 of age. It has been well documented that maximum development of the small intestine occurs at 10 first day of age [22], therefore adequate feeding in the first days has an important role in broiler chicken performance [10].…”

“…Glutamine dietary supplementation decreases health problems, prevents intestinal atrophy, maintains antioxidant status, decreases incidence of diarrhea, resulting in increased weight gain and improved efficiency (Haynes et al, 2009;Zhong et al, 2011;Wang et al, 2014;Watford, 2015). Similar results have also been reported in broiler chicken (Nassiri Moghaddam and Alizadeh-Ghamsari, 2013;Jazideh et al, 2014;Nascimento et al, 2014;Manvailer et al, 2015;Muro et al, 2015;Olubodun et al, 2015;Ribeiro Jr et al, 2015;Luquetti et al, 2016;Maiorka et al, 2016;Namroud et al, 2017).…”

After a collaborative and uninterrupted work, the UPS has continued to improve one more year as a Research University, and has gone from the position 6,611 in the world and 13 in Ecuador (Webometrics, 2013) to the position 2627 (Webometrics, 2020) worldwide, it is the 170 on the continent and 7 in Ecuador. The continuous improvement of all teams and the strategic vision have made progress in the World Ranking, allowing to go to 3984 positions in 7 years and 366 new positions compared to 2019. Within this global strategy of improvement of the UPS as a Research University, LA GRANJA, belonging to the area of Life Sciences, was the first university publication of Ecuador to be included in SCOPUS, Elsevier publishing house and indexed in the Emerging Source Citation Index of the Web of Science (WOS). This edition presents articles by authors from 5 countries and 16 Universities and Research Centers. We started this number 31 with the topic of weather monitoring, in an effort between the Sciences Department of Environmental Systems of Switzerland and Universidad de Cuenca, led by Dr. Ryan Padrón and his excellent team. In addition, researchers from Universidad de las Fuerzas Armadas, led by Teófilos Toulkeridis, analyze the problem of perceptions in the important and current topic of Climate Change.
