“…Body weights in different ages were a significantly improved, squabs fed the highest ME and CP level (16-18% with 3000 Kcal ME/kg) of diet recorded significantly highest body weight and average daily gain contrast with other treatments. These results are in the line with others who pointed out that 15.5% protein and 16% CP had a significant positive influence on average BW in growing squabs from 28 days to 6 th month of age [5,10]. While, these results disagreed with Abdel-Azeem [11], who recommended that the best protein level of Baladi pigeons diets was 14% CP with 3100 ME kcal/kg that produced the better performance (fertility, livability, squab production, the return of squabs and body measurements of squabs).…”

This study was conducted to evaluate the effect of nine diets through the application of 3×3 randomized design which included three levels of energy (2600, 2800 and 3000 Kcal/kg) with 3 supplemental protein levels (14, 16 and 18%) on growth performance, blood parameters, carcass yields and economic efficiency of Baladi pigeon squabs from 28 days old until 6 months of age (age of sexual maturity). A total of 135 pairs of squabs were randomly and independently allocated to the nine dietary treatments, each containing 15 pairs (3 replicate of 5 pairs). The diets were formulated in mash form fortified with vitamin and mineral premix. Moreover, feed and water were provided for ad-libitum consumption. The results showed that, squabs fed higher energy and crude protein diets (3000 ME+16% CP) had higher live body weight with a coincident significant decrease of the feed intake (P<0.0001). In addition, dressing (%), breast and thigh meat yield (%) increased significantly with increasing levels of both energy and protein, where they hit the peak values in squabs fed on 3000 ME+16% CP diet. Furthermore, increasing energy levels did not affect serum proteins (albumin and globulin), urea and uric acid. However, it had a significant positive effect on serum lipids (cholesterol, triglyceride, high density lipoprotein and low density lipoprotein). In terms of economic analysis, 3000 ME+16% CP diet revealed the lowest cost per Kg live weight of birds 81.87 L.E per pair, along with the highest economic return 110.3 L.E per pair and net profit 10.43 L.E per pair. In conclusion, squabs can efficiently utilize diet containing high energy (3000 Kcal/kg) and crude protein (16%) diets, consequently, it can be used to optimize their growth performance and maintain the maximum economic return.

“…In addition, it is very delicate, lean (low cholesterol), easily digested and considered as fancy meat because of its taste and delicacy [2,3]. Until now, there is insufficient information about nutrient requirements or growth curves of pigeons, as the National Research Council (NRC) has not provided any standards or guidelines [4,5].…”

“…The energy, crude protein [8], methionine and lysine levels [9] of the basal diet were referenced by a previous study and are often used by major pigeon farms. Ca levels of 0.60%, 0.90%, 1.20%, 1.80%, 2.40% and 3.00% in a corn-soybean complete pellet feed were fed respectively to six groups of pigeons.…”

In order to confirm the dietary calcium (Ca) requirement to keep a balance of the production performance and the albumen transparency, the study examined the effects of different dietary Ca levels on the production performance, egg quality, and albumen transparency of laying pigeons. 1080 pigeon pairs were randomly allocated into six treatment groups, each consisting of six replicates of 30 pigeon pairs per treatment. Ca levels of 0.60, 0.90, 1.20, 1.80, 2.40, and 3.00% were fed. The results showed that the laying rate, average egg weight, and feed to egg ratio were significantly influenced by Ca levels (p < 0.05). Albumen percentage, albumen height, Haugh unit, and eggshell thickness at 8 w and 16 w were significantly influenced by Ca levels (p < 0.05). The L*, a*, b*, and c* values of cooked albumen at 8 w and 16 w were all significantly influenced by Ca levels (p < 0.05). After 16 w of feeding different Ca levels, the percentage of transparent eggs had an early increasing and later decreasing trend. In conclusion, taking the transparency of pigeon eggs as an assessment index and considering production performance secondly, the optimal level of dietary Ca for laying White King pigeons is 0.90%.

“…Pigeons engage in close pair bonding, produce two eggs in a laying period, and squabs are fed with crop milk regurgitated from both parents [ 17 , 18 ]. The breeding cycle of pigeons in the wild is nearly 2 months [ 19 ], and Khargharia et al (2003) reported a mean clutch interval of 47.44 days [ 20 ]. These parameters could be improved meet increasing consumer demand.…”

Deep sequencing identification of miRNAs in pigeon ovaries illuminated with monochromatic light

BackgroundThe use of light of different wavelengths has grown popular in the poultry industry. An optimum wavelength is believed to improve pigeon egg production, but little is known about the role of microRNAs (miRNAs) in the effects of monochromatic light on ovarian pigeon function. Herein, we harvested ovaries from pigeons reared under monochromatic light of different wavelength and performed deep sequencing on various tissues using an Illumina Solexa high-throughput instrument.ResultsWe obtained 66,148,548, 67,873,805, and 71,661,771 clean reads from ovaries of pigeons reared under red light (RL), blue light (BL), and white light (WL), respectively. We identified 1917 known miRNAs in nine libraries, of which 524 were novel. Three and five differentially expressed miRNAs were identified in BL vs. WL and RL vs. WL groups, respectively. Quantitative reverse transcription PCR was used to validate differentially expressed miRNAs (miR-200, miR-122, and miR-205b). In addition, 5824 target genes were annotated as differentially expressed miRNAs, most of which are involved in reproductive pathways including oestrogen signalling, cell cycle, and oocyte maturation. Notably, ovarian miR-205b expression was significantly negatively correlated with its target 11β-hydroxysteroid dehydrogenase type 1 (HSD11B1).ConclusionsmiRNA–mRNA network analysis suggests that miR-205b targeting of HSD11B1 plays a key role in the effects of monochromatic light on pigeon egg production. These findings indicate that monochromatic light shortens the oviposition interval of pigeons, which may be useful for egg production and pigeon breeding.Electronic supplementary materialThe online version of this article (10.1186/s12864-018-4831-6) contains supplementary material, which is available to authorized users.
