“…This is the first morphological evidence of any form of head (head-base bending) or neck (disjointed sperm) "bending" taking place in the avian testis. Despite numerous publications on "bent" or "crooked-necked" sperm [2,4,[9][10][11][12][13][14][15][16][17][18][19]23,26] in birds, no information on the origin of this defect has been presented. Both defects could conceivably also develop in the ductus deferens due to a combination of inherent and external factors.…”

“…Some authors have adopted a generalized approach and simply refer to head, midpiece and tail (flagellum) bends [3,7,8], while others qualify the degree of bending, recognizing 90° and 180°h ead and tail bends as well as midpiece bending [9][10][11]. Other descriptions of bending are more specific and define the precise area where the bend occurs.…”

The accurate assessment of avian sperm abnormalities is hampered by a lack of descriptive data and by the confusing terminology currently in use. Critical appraisal of semen samples from the distal ductus deferens of the emu revealed that two closely related yet separate (distinct) defects previously collectively referred to as "bent sperm" or "crooked-necked sperm" could be identified by light and electron microscopy. Head-base bending typically involved a 180° bend at the base of the nucleus which placed the head and midpiece into close apposition and parallel to each other. No part of the neck or midpiece was involved and bending was restricted exclusively to the base of the nucleus. Incomplete chromatin condensation was always associated with the bend. Disjointed sperm, which superficially resembled "bent" sperm, showed complete separation of the neck from 2 the head-base at the level of the connecting piece. All structural elements of the neck region appeared normal. In both defects the region of contact between the head (nucleus) and the neck/midpiece was enclosed as a unit by the plasmalemma. Both defects were observed to originate in the testis; however, their subsequent expression in the ductus deferens cannot be ruled out. These results confirm that head-base bending of emu sperm represents a head defect, whereas disjointed sperm should be classified as a tail (neck/midpiece) defect.

“…Our findings on sperm morphology attest to Shanmugam et al (2012), Almahdi et al (2014) and Ameen et al (2014) who reported nonsignificant variation in the sperm morphology in different breeds/strains of cockerels. Tabatabaei et al (2010) observed an increase in rate of sperm morphological defect in Iranian indigenous broiler breeder chickens with aging of roosters. Tanemura et al (1993) attributed such defects to impaired spermatids and spermatocytes resulting in interrupted spermatogenesis.…”

mL -1 at 40 weeks whereas total sperm count/ejaculate was highest at36 weeks of age. Sperm viability ranged from 70.60-80.00% and did not vary between the two breeds at different ages. It can be concluded that though there exist marginal variations in spermatological traits of the normal feather and naked neck roosters due to their genetic constitution and age, both breeds could still be used efficiently in planning artificial insemination/breeding programmes for genetic improvement of the Nigerian local chicken since the results obtained were within the accepted reference range for chickens.

“…Oleh karena itu, asupan nutrisi yang tepat sangat penting untuk menjaga kinerja reproduksi ayam jantan. Tabatabaei et al (2010) menunjukkan bahwa volume semen menurun seiring dengan bertambahnya umur dan penurunan berat badan ayam jantan. Penurunan volume ejakulasi akibat bertambahnya umur ayam mendukung hasil penelitian sebelumnya yang melaporkan bahwa ejakulasi semen ayam jantan menurun seiring dengan menurunnya berat badan (Fouad et al 2020).…”

ABSTRAKSemen adalah cairan yang dikeluarkan oleh organ kelamin ternak jantan yang secara normal diejakulasikan ke dalam saluran reproduksi ternak betina melalui kopulasi. Evaluasi semen merupakan alat utama untuk memprediksi kinerja reproduksi ternak ayam jantan. Evaluasi kualitas semen penting dilakukan untuk menyelesaikan salah satu masalah utama dalam peternakan pembibitan ayam, yaitu rendahnya fertilitas. Faktor terbesar dari sumber masalah tersebut terkait dengan rendahnya kualitas semen ayam. Kualitas semen ayam lebih banyak dipengaruhi oleh faktor non genetik, seperti faktor pakan dan nutrisi. Tujuan dari penulisan makalah ini adalah untuk mengkaji hasil-hasil studi terkait pengaruh pakan terhadap kualitas semen ayam. Hasil studi menunjukkan bahwa faktor pakan sangat mempengaruhi kualitas semen ayam, terutama imbangan energi metabolis-protein dalam pakan ayam jantan sangat penting diatur untuk menjaga berat badan ayam jantan agar tidak terjadi kelebihan atau kekurangan berat badan yang sangat mempengaruhi kualitas semen ayam. Suplementasi suplemen dan imbuhan pakan menjadi upaya yang dapat dilakukan untuk meningkatkan kualitas semen ayam. Jenis suplementasi yang dapat dilakukan dengan bahan sumber antioksidan, asam amino, mikromineral, bahan mengandung bioaktif tanaman, bahan sumber asam lemak dan probiotik. Disimpulkan bahwa faktor pakan sangat menentukan terhadap kualitas semen ayam.Kata kunci: ayam jantan, kualitas semen, pakanABSTRACTRooster semen is a liquid released by the genitals of the roosters which is normally ejaculated into the female reproductive tract during copulation. Semen evaluation is the main way to predict the reproductive performance of roosters. Semen quality evaluation is important to solve one of the main problems in poultry breeding farms, namely low fertility, whereas the biggest factor of this problem source is related to the poor of roosters’ semen quality. The quality of roosters semen is more influenced by non-genetic factors, such as feed and nutrition. The purpose of this paper was to examine the results of studies so far related to the effect of feed on the roosters’ semen quality. The results of the study indicated that the feed factor greatly influences the quality of roosters semen. The metabolic energy-protein balance in the rooster's feed was very important to regulate to maintain the weight of the rooster so as not to overweight and underweight because bodyweight greatly affects the quality of roosters semen. Supplementation of feed supplements and feed additives was an effort that can be done to improve the roosters semen quality. The kind of supplementation that could be done was supplementation of antioxidant sources, amino acids, microminerals, materials containing plant bioactive, fatty acid source ingredients, and probiotics. It was concluded that the feed factor was crucial to the quality of semen quality produced by the roosters.Keywords: feed, rooster, semen quality
