“…In our study the villus length increased with increasing chitosan levels and reached maximum at concentration levels 1 & 2 g•kg diet −1 as shown in Table 5 and Figure 3. The crypt is the area where stem cells divide to permit the renewal of the villus, and a large crypt indicates fast tissue turnover and a high demand for new tissue [39]. The ratio of villus height to crypt depth is a useful criterion for estimating the digestive capacity in the small intestine [40].…”

The effect of chitosan incorporated into feed formulation on the growth, feed utilization, body composition and histological response of sea bass (Dicentrarchus labrax) was investigated. Final fish weight, feed conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER), protein productive value (PPV), and energy utilization (EU) of sea bass feed chitosan supplemented diet and the control diet were determined at the end of experiment. Data presents mean ± SD from triplicate determination (n = 3) for 75 days feeding trial. Different concentrations (0.5, 1.0, 2.0, 3.0 & 4.0) and control without chitosan incorporated with total fish feed in the form of dry diets were fed for 75 days. Average final weight (FW) was significantly higher at diet 3 (1 g•kg −1 chitosan) and the lowest in control fish group, specific growth rate (SGR) was significant at diet 3. Also, protein efficiency ratio (PER), protein productive value (PPV), and energy utilization (EU) showed the same trend. The chemical body composition, crude protein, dry matter, crude fat and ash were significant (P ≤ 0.01) different compared to control groups. The present investigation suggested that the chitosan incorporated into diets of sea bass fish certainly enhanced the non specific responses and reduced mortality and also improved the growth performance of fish.

RESUMO.-Caracterizou-se morfologicamente o tubo digestório de frangos de corte da linhagem Cobb 500 ® . O experimento foi conduzido no setor de avicultura do Colégio Téc-nico de Bom Jesus, Piauí, em galpão experimental. Foram utilizados oito animais aos quarenta e seis dias de idade, e avaliou-se as características morfológicas macroscópica a partir da mensuração dos órgãos do tubo digestório, essas foram avaliadas através de análise estatística descritiva e análise correlação de Pearson. A avaliação microscópica foi realizada pela análise das lâminas histológicas. Conclui-se que a linhagem Cobb 500 ® demonstrou estratigrafia tecidual do tubo digestório, composta por quatro túnicas: mucosa, submucosa, muscular e serosa, com exceção do esôfa-go e inglúvio que ao invés de possuir túnica serosa possui a adventícia. No esôfago há presença de glândulas mucosas, e no inglúvio são ausentes. O proventrículo é estruturado por várias glândulas mucosas localizadas na túnica mucosa, que drenam suas secreções em ductos secundários e primários e ao um ducto excretor em direção ao lúmen do órgão. O ventrículo possui um conteúdo queratinóide na túnica mucosa, glândulas gástricas na lâmina própria. No intestino delgado é mais visível a presença de células caliciformes no íleo, porém também estão presentes no duodeno e no jejuno. Em ambos os intestinos delgado e grosso é visível à presença de vilos, que se tornam mais curtos e lar-

“…Diarrhoea incidence (DI) was estimated by pen as the number of days in which pigs showed clinical signs of diarrhoea symptoms as a proportion of the total number of days of the trial. The evaluation standard was as follows: 1 = hard, dry pellet, 2 = firm, formed faeces, 3 = soft, moist faeces that retains shape, 4 = soft, unformed faeces that assume the shape of the container, and 5 = watery liquid that can be poured (Hu et al 2012).…”

A total of 120 weanling pigs [(Landrace × Yorkshire) × Duroc], 21 days of age with an average initial body weight (BW) of 6.52 ± 0.22 (SE) kg were selected to investigate the effects of extruded rice product as a replacement for dried whey on growth performance, coefficient of total tract apparent digestibility (CATTD), blood profiles, faecal shedding of Lactobacillus and Escherichia coli (the microbial counts of digesta were expressed as log 10 colony forming units per gram), and faecal scores of weanling pigs. Pigs were randomly allocated to one of four dietary treatments, with six replicates per treatment and five pigs per pen. Pigs in the control group were fed a diet based on corn, soybean, and 20% dried whey. Experimental groups received the same diet as the control group, but dried whey was replaced by 3%, 6%, and 9% extruded rice. Throughout the experimental period (six weeks), no differences were observed in the average daily gain, average daily feed intake, and gain/feed ratio. Pigs fed 6% and 9% extruded rice had a lower (P < 0.05) CATTD than pigs fed the control diet on Day 14. The blood creatinine concentration of pigs fed 9% extruded rice was higher (P < 0.05) than that of pigs in the control group on Day 14. Pigs fed the diets containing 6% and 9% extruded rice had decreased (P < 0.05) faecal E. coli counts on Day 14 compared with pigs fed the control diet. The current results indicate that feeding extruded rice can decrease faecal E. coli counts without negative effects on growth performance in weanling pigs.
