Reflux of 15N-labeled uric acid after intracloacal infusion in broiler chickens fed low- or high-protein diets. Poult Sci 2022; 101:101724. [PMID: 35196586 PMCID: PMC8866718 DOI: 10.1016/j.psj.2022.101724] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 12/13/2021] [Accepted: 01/08/2022] [Indexed: 11/24/2022] Open
Abstract
Reflux of urine from the cloaca into the ceca provides chickens with a mechanism for recycling of urinary-Nitrogen (N) in a way analogous to urea recycling in mammals. However, it is unknown if reflux has substantial relevance in current poultry husbandry, where birds are fed ad libitum and have high protein intake. To evaluate the fate of urinary-N in ad libitum-fed broiler chickens, 15-day-old broilers were assigned to a high (21.9% CP, n = 22) or low (10.2 % CP, n = 22) protein diet. At 25 d of age, 20 broilers per dietary treatment were infused into the cloaca with a pulse dose of 107 mg [1,3-15N]-uric acid. N-contents and 15N-enrichment in digesta, blood plasma, and body tissues were measured at 5, 30, 60, 90, 150, 300, 450, 600, 1,200, or 1,800 min after administration (n = 2 /time-point /diet). Two broilers per dietary treatment were infused with saline and served as control to analyze background 15N-enrichment. The average total recovery (% of infused (w/w)) of 15N from infused uric acid in all body tissues was low (2.9 ± 0.62 %), of which the largest proportion was found in carcass tissue (2.5 ± 0.60%). 15N-enrichment was greatest in intestinal tissues. Even at 1,200 min, 15N-enrichment of ceca (0.46 ± 0.169 APE) and colon (0.13 ± 0.159 APE) digesta was considerably exceeding background enrichment. 15N-enrichment in excess of background enrichment in cecum and colon digesta (10-fold, P < 0.05), and 15N recovery in intestinal tissues (4-fold, P < 0.01) were greater in birds fed the low protein diet compared with the high protein diet, speculatively pointing out differences in the occurrence of reflux, incorporation of uric acid-N derivatives in intestinal tissues by first-pass metabolism, and a prolonged digesta retention time in protein deficient birds. In conclusion, these data confirm that uric acid-N infused in the cloaca can be refluxed and used for body N-deposition, but its contribution to whole body protein metabolism in broilers is probably limited.

Characterization of Cecal Smooth Muscle Contraction in Laying Hens. Vet Sci 2021; 8:vetsci8060091. [PMID: 34073160 PMCID: PMC8226868 DOI: 10.3390/vetsci8060091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 05/19/2021] [Accepted: 05/24/2021] [Indexed: 11/24/2022] Open
Abstract
The ceca play an important role in the physiology of the gastrointestinal tract in chickens. Nevertheless, there is a gap of knowledge regarding the functionality of the ceca in poultry, especially with respect to physiological cecal smooth muscle contraction. The aim of the current study is the ex vivo characterization of cecal smooth muscle contraction in laying hens. Muscle strips of circular cecal smooth muscle from eleven hens are prepared to investigate their contraction ex vivo. Contraction is detected using an isometric force transducer, determining its frequency, height and intensity. Spontaneous contraction of the chicken cecal smooth muscle and the influence of buffers (calcium-free buffer and potassium-enriched buffer) and drugs (carbachol, nitroprusside, isoprenaline and Verapamil) affecting smooth muscle contraction at different levels are characterized. A decrease in smooth muscle contraction is observed when a calcium-free buffer is used. Carbachol causes an increase in smooth muscle contraction, whereas atropine inhibits contraction. Nitroprusside, isoprenaline and Verapamil result in a depression of smooth muscle contraction. In conclusion, the present results confirm a similar contraction behavior of cecal smooth muscles in laying hens as shown previously in other species.

Phytate degradation, myo-inositol release, and utilization of phosphorus and calcium by two strains of laying hens in five production periods. Poult Sci 2020; 99:6797-6808. [PMID: 33248595 PMCID: PMC7704748 DOI: 10.1016/j.psj.2020.08.064] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 08/04/2020] [Accepted: 08/19/2020] [Indexed: 12/17/2022] Open
Abstract
The objective of this study was to compare 2 laying hen strains in 5 production periods regarding phytase activity, phytate (InsP6) degradation, and myo-inositol (MI) release in the digestive tract and phosphorus (P) and calcium (Ca) utilization. One offspring of 10 nonrelated roosters per strain (Lohmann Brown-classic (LB) or Lohmann LSL-classic (LSL)) was placed in one of 20 metabolic units in a completely randomized block design in week 8, 14, 22, 28, and 58 of life. All hens were fed the same corn and soybean meal–based diet at one time, but the diet composition was adjusted to the requirements in the respective period. For 4 consecutive days, excreta were collected quantitatively at 24-hour intervals. In week 10, 16, 24, 30, and 60, the blood plasma, digesta of crop, gizzard, jejunum, ileum, and ceca, and mucosa of the jejunum was collected. The concentration of inorganic P in the blood plasma was higher in LB than in LSL hens (P = 0.026). Plasma Ca concentrations increased with each period (P < 0.001) in both strains. In jejunum digesta, the MI concentration did not differ between strains, but InsP6 concentration was higher in LB than in LSL hens (P = 0.002) and the highest in week 30 and 60. Total phosphatase and phytase activities were higher in LB than in LSL hens (P ≤ 0.009). Period effects were also significant for these enzymes. Concentrations of some constituents of the cecal content were different between the strains. The MI concentration in the egg albumen and yolk was higher in LB than in LSL hens. Differences in InsP6- and MI-related metabolism of the 2 hen strains existed. These differences were partly dependent of the period. Especially, week 24 was a period of remarkable change of metabolism. Great differences also existed among individuals, making it worth to have a closer look at the metabolism of individuals in addition to evaluating treatment means. Further studies on metabolic, genetic, and microbiome level may help explain these differences.

Abstract
An experiment was conducted to study the effect of dietary supplementation of Moringa oleifera leaf meal (MOLM) on the performance of Vanaraja laying hens. Five experimental diets were formulated by supplementing without (T0), and with MOLM @ 0.5 kg (T0.5), 1.0 kg (T1.0), 1.5 kg (T1.5) and 2.0 kg (T2.0) per 100 kg basal diet. Sixty laying hens (22 weeks) were divided into 5groups (each group had 4 replicates with 3 laying hens per replicate)and were randomly fed the above 5 experimental diets. All the birds were reared on wire mesh floored cages during the experimental period of 8 weeks. The MOLM contained 27.27% CP, 3.76% EE, 18.53% CF, 11.50% TA and 0.37% AIA. There was improvement (P<0.05) in egg production and feed conversion ratio (FCR) in T0.5 than T0. The average egg weight in T2.0 was lower compared to T0 and T0.5. The egg quality characteristics viz. albumen (%), yolk (%), shell (%), shape index and shell thickness (mm) were similar for all the treatments.The feed cost to produce dozen egg was highest for T0 (rupees 27.98) and lowest for T0.5 (rupees 22.33). It can be concluded that supplementation of Moringa oleifera leaf meal @ 0.50 kg/100kg diet in Vanaraja laying hens was beneficial in terms of improved egg production, better FCR and reduced cost of feed to produce dozen eggs.

Abstract
One of the environmental challenges that modern poultry industry faced is odor pollution caused by ammonia emission. The objectives of the study were to determine the effect of sodium butyrate on the production of ammonia in the cecal contents of laying hens using in vitro gas production study and to elucidate the mechanism behind it. The study consisted of a control (without sodium butyrate), and three experimental groups added with 10, 15, and 20 mg of sodium butyrate, respectively. Results showed that ammonia production in headspace of the syringe decreased by 8.2, 23, and 23 %, respectively, while ammonium production from the fermentation broth decreased by 6.3, 14.4, and 13.7 %, respectively. Sodium butyrate had no significant effect on the contents of uric acid and urea, nitrate-N, or total N in all treatments. However, sodium butyrate decreased the urease and uricase activities (P < 0.05) in the fermentation broth. Sodium butyrate also altered volatile fatty acids profile of the fermentation broth by decreasing the production of isovalerate (P < 0.05) and increasing those of acetate, butyrate, and isobutyrate (P < 0.05). The MiSeq System Sequencing results showed that sodium butyrate increased the relative abundance of Bacteroides and Faecalibacterium (P < 0.05) and decreased the relative abundance of Desulfovibrio, Helicobacter, and Campylobacter (P < 0.05).Our results concluded that sodium butyrate changes the diversity and relative abundance of the microbes which altered the fermentation characteristics leading to reduction in ammonia production.

Abstract
The alterations in the balance of the normal intestinal bacterial flora of chickens exposed to acidified wood-derived litter were analyzed and compared to those of a control group exposed to nonacidified litter. A total of 1,728 broilers were divided into two groups, with six replicates in each. One group was exposed to dry wood-derived litter, and the other was exposed to dry wood-derived litter sprayed with a mixture of sodium lignosulfonate, formic acid, and propionic acid. At five different times, five chickens from each pen were killed and the intestinal contents from ileum and caeca were collected. The samples were diluted and plated onto selective media to identify coliforms, Lactobacillus spp., Clostridium perfringens, and Enterococcus spp. Covariance analysis of bacterial counts showed significantly lower counts for C. perfringens in the caeca and the ileum and for Enterococcus spp. and Lactobacillus spp. in the ileum in chickens exposed to the acidified litter. Lactobacillus spp. showed significantly higher counts in the caeca in chickens exposed to acidified litter. There was no difference between the two litters with regard to coliforms in the ileum and the caeca or to Enterococcus spp. in the caeca. The study shows that exposing the chickens to acidified litter lowers the intestinal bacterial number, especially in the ileum, without negative consequences for the chicken's health or performance. Of special interest are the lower counts of C. perfringens and Enterococcus spp. that might reduce the risk of developing clinical or subclinical necrotic enteritis and growth depression.
