Effect of different fat sources in parental diets on growth performance, villus morphology, digestive enzymes and colorectal microbiota in pigeon squabs

Abstract

The influence of different fat sources in pigeon diets on performance, gut morphology, digestive enzymes and colorectal microbiota of their squabs was investigated from hatching to 28 days of age. Parent White King pigeons (240 males and 240 females) were randomly assigned to four dietary treatments, each including six replications of 10 pairs (one pair per cage). Four hundred eighty newly hatched squabs were randomly allocated, and two squabs were raised by a pair of parent pigeons. Pigeons were fed a basal diet supplemented with 6% lard oil (LO), palm oil (PO), soybean oil (SO) or fish oil (FO), respectively. After four weeks of experimental feeding, FO inclusion caused the lowest body weight gain of squabs and the highest lipase activity in the jejunum content. Compared with other treatments, Group SO showed a greater villus height and duodenal surface area in squabs. In Group PO the alkaline phosphatase activity in duodenal mucosa of squabs was decreased, while in Group LO the alkaline phosphatase activity in the jejunal mucosa was highest. The leucine aminopeptidase (LAP) activity in the duodenal, jejunal and ileal mucosa of squabs was highest in Group SO. In the colorectal content of squabs, in Group LO the highest percentages of microbiota of the enteric group (Clostridium, Bifidobacterium, Coriobacterium and Bacteroides-Porphyromonas-Prevotella) were induced. Because supplementation of SO has beneficial effects on gut development and digestive function at comparable growth performance, it is probably a better choice for oil supplementation in parental pigeon diets.

Effects of dietary oil sources and calcium : phosphorus levels on growth performance, gut morphology and apparent digestibility of broiler chickens

“…The crypt depth of the duodenum and jejunum was greater (P <0.05) in birds fed LO than in other treatments in both the starter and finisher phases. The lower villi height in LO birds supported the findings of Xie et al (2013), who reported that supplementing oil rich with n-3 polyunsaturated fatty acids (PUFA) in diet of squabs caused a lower bodyweight gain and affected villus morphology compared with lard, palm oil and soybean oil. Oils containing high proportions of readily oxidizable n-3 PUFA could lower the oxidative stability of gut, which could predispose cell or tissue to free radical attack.…”

“…Treatment 3 which had the best conversion ratio included only 3% soybean oil. This is related to the effect of fat on feed intake which causes fixed energy absorption of the bird by lower feed intake [16] .…”

“…Research on animals was conducted in Rudsar, Iran (37.1378° N, 50.2836° E) and all the procedures used were approved by the Ethics Committee in Animal Use (Approval date: 10/05/2016; No: 10038). The experiment, in a completely randomized design with 6 treatments and 4 replicates using 240 1-day-old male chicks of strain Ross 308, was conducted in the starter period (1-10 day), grower period (11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28) and finisher period (29-42). Each replication included 10 chicks.…”

“…The ingredients, nutrient levels and analyzed LA content of experimental diets for parent pigeons were shown in Table 1. The fatty acid composition of each diet analyzed according to Xie et al [18] were shown in Additional le 1. The pigeons were given to water ad libitum and were fed twice daily (7:00 a.m. and 3:00 p.m.) throughout the experiment.…”
