Abstract The present study aimed to evaluate the effect of organic and inorganic selenium (Se) supplementation on semen quality blood serum profiles buffalo bulls. Nine mature bulls were divided into three groups: control (non‐supplemented); Se (10 mg Sel‐Plex®/head twice weekly) sodium selenite/head weekly). Semen was collected a week for 3 months during supplementation. properties evaluated from fresh ejaculate. Moreover, fructose concentration, aspartate alanine transaminase (AST ALT)...
The aim of the present study was to evaluate effect a pretreatment with insulin on response buffalo cows inactive ovaries gonadotrophin-releasing hormone agonist (GnRHa) treatment during hot summer months (July and August). Thirty-six Egyptian were randomly allocated into three groups: (1) group treated GnRHa (G1, n = 16) in which each received an intramuscular injection 250 mg (Day 0; gonadorelin, Fertagyl); (2) before (G2, 8) subcutaneous biphasic at dose 0.25 IU kg(-1) bodyweight once...
A total number of 600 female buffaloes, having 3321 lactation records, from first to tenth parity, kept at three experimental farms (Mahalet Mousa, El-Nataf El-Gaded and El-Kadem), belonging the Animal Production Research Institute, Ministry Agriculture, Cairo, Egypt, during period 2000 2007 were used study genetic phenotypic progress, achieved by Mixed Model Equations (MME) for Best Liner Unbiased Prediction. The sires 66 average daughters per sire 12.50. Least square analyzed was estimate...
The transition period is extremely critical for pregnant producing animals. However, there very limited research on the metabolic and immunological changes in Egyptian water buffalo cows during period. Therefore, this study was conducted to investigate immunometabolic occurring cows.A total of 50 multiparous were subjected weekly blood sampling 3 weeks before calving after day parturition determine complete count, including red cell leukocyte count (TLC), differential hemoglobin level,...
This study was carried out at Mehallet Mousa Experimental Stations, belonging to Animal Production Research Institute evaluate the effects of methergin or oxytocin administration 0 24 hours after calving on uterine involution and pregnancy rate buffalo cows.About 20 multiparous Egyptian cows with normal parturition having (400-650 kg) live body weight, (2-7) parities (2.5-3.5)body condition score were used in this study.Animals divided into five groups (n=4/each).Animals 1 st group i.m....
Estimates of (co)variance component and genetic parameters using multi-traits animal model, traits studied were lactation period (LP), total milk yield (TMY), days open (DO).In all lactations based on 4745 records Egyptian buffaloes calved during the from 1980 to 2014 at Mehallet Mousa Experimental farms Animal Production Research Institute (APRI), Ministry Agriculture.The six mixed model used in analysis included non effects month year calving, parity, random additive direct genetics,...
The present work was conducted to evaluate the efficacy of two superovulatory regimens determine diameter follicle using ultasonography monitoring ovarian activity for superovulation in 21 buffalo cows, giving PMSG and PGF2α.Superovulation regime done by injection (3000 IU) when follicular dominant follicles reach 5-7 mm (G1, n=7), >7-9 (G2, n=7,) >9 (G3, n=7).Buffaloes all groups were injected with 2 ml PGF α naturally inseminated depend on detection estrous within 48-72 h...
Uterine and cervical involutions were judged by transrectal ultrasonography (US) versus rectal palpations (RP) in buffaloes (n =26). The diameters of the pregravid uterine horn (PGUHD) cervix (CvD) estimated both US RP every three days until gross or involution. Also, US-measured PGUHD CvD recorded on day involution basis RP. combined thickness myometrium perimetrium (PGUHMPT) wall (CvWT) parallelly with US-measuring CvD. intervals to (P< 0.05) 0.01) involutions, RP, shorter than those...
The present study aimed to display effects of age at first services, calving (AFC), interval, days open, number services per conception, dry, season on total milk yield (TMY) and 305 (305MY).Also, estimate effect parity interval (CI) open then the level production service service, calving, open.Heritability estimates for 305-day (0.18), dry period (DP) (0.12), TMY (0.17) CI (0.19).High heritability were obtained AFC (0.68) lactation length (LL) (0.78).There high positive genetic phenotypic...
The Objective of this study was to measure the protein profiles seminal plasma in Egyptian buffalo bulls semen and examine their correlation with characteristics Mehalet Mousa .Semen 20 ( divided into high low fertile bull, 10 for each group, according records insemination) were collected twice weekly 12 weeks by artificial vagina (ejaculate volume, motility , abnormalities, viability sperm cell concentration recorded .Seminal seperated centrifugation treated cold ethanol then underwent...
Total of 30 Egyptian buffalo heifers (20-25 months and 340-360 kg) failed to conceive after 3 services (repeat breeder heifers) were exposed three hormonal protocols exhibiting the 4 th estrous cycle.In 1 st protocol, (n=10) injected with GnRH on day estrus service.In 2 nd (0 day), followed by PGF α 7. Heifers displaying within 48 hr injection served, while those did not show h a second dose 9 served 10.In rd starting 6 cycle.Animals 72 exhibit re-injected 11 days 24-48 later.Pregnancy was...
The present study was conducted to investigate the effect of semen extenders on characteristics cooled buffalo and determine suitable extender which will give higher conception rate.Semen collected from five (5-6 years) bulls twice weekly using artificial vagina.Freshly samples were evaluated ejaculates at least 70% individual motility 6x10 6 sperm /ml pooled, divided into three parts, diluted with tris egg yolk, citrate yolk or skimmed milk slowly 5 o C. Semen for motility, alive sperm,...
This study's goal was to use the DNA sequence techniques find new mutations in folliclestimulating hormone receptor exon 10 (FSHR) Egyptian buffalo bulls with different sperm motility.A total of 50 aged 3-4 years old, at Kafr El-Sheikh Governorate (breeding station Mahallet Mousa), Egypt were investigated.The divided into two groups according spermatozoa motility: first group high motility (> 60%, n = 32) and second low (< 18).Blood samples collected obtain genomic deoxyribonucleic acid,...
