A morphological, biochemical and physiological study has been made of the effects of chloroquine-diphosphate (a membrane stabilizer) on the preservation of buffalo spermatozoa in five modified dilutors designated here as Al’ A2’ A3, A4 and CAW. In almost all the five dilutors, there was significant (p< 0.01) progressive increase in the percentage of sperm abnormalities and the release of enzyme...

This study was conducted at the College of Agriculture – University Anbar, Iraq. From 16 January to 5 February 2022, this aimed investigate effect injected egg hatching different sialic acid times in growth and embryonic development. Four hundred eggs types (Ross 308) were with concentrations 0 days (before placing incubator), 7 14 incubation. Eggs divided into four groups (100 each) as follows...

The aim of the study was to evaluate the effect of the addition of 20% bull seminal plasma to semen extenders on post-thaw sperm motility, morphology, and fertility. Two Merino rams at 3-5 years of age, 43 ewes, and one Holstein bull were used. Fourteen ejaculates were collected by the use of an artificial vagina, twice a day, at 60 min interval. Six semen ejaculates were extended with Tris-egg...

The experiment was designed to evaluate the optimal concentration of egg yolk in extender for diluting Barbari buck semen during short-term storage at 4oC. A total of four Barbari bucks were used as semen donors during the experiment. The observed mean (±SE) valuesrecorded for percent live spermatozoa ranged from 63.5 ± 1.08 to 75.33 ± 0.99, percent progressive motile spermatozoa ranged from 54...

This experiment was conducted in order to investigate the effect of chelated form trace elements diet on production traits, immunity, and blood parameters Ross 308 broiler breeder chickens. Treatments included Treatment 1 (Negative control): Mn, Se, Cu, Fe Zn provided as non-chelated form; 2 (Positive 3: 50% 4: 5: Cu 6: 7: Mn 8: Se form. The results showed that over entire period egg mass were ...

Rat immunoglobulin (IgG) was covalently bound to N-(2-hydroxypropyl)methacrylamide (HPMA) copolymers via glycylglycyl spacer. The resultant conjugate, free IgG and HPMA copolymer (containing a low percentage of tyrosinamide to facilitate radiolabelling) were radioiodinated, and their rates of pinocytic uptake, intracellular degradation and exocytic release by rat visceral yolk sacs cultured in ...

Cryopreservation of goat spermatozoa is a valuable tool for genetic management. Previous studies have shown the frezeeablity of spermatozoa from various goat breeds but also have difficulties with available protocols. Therefore, we want to investigate the effects of centrifugation and different egg yolk ratios (5% and 10%) on spermatological parameters of Norduz goat spermatozoa. A total number...

The effects of L-carnitine supplementation (50-500 mg/kg diet) of a practical layer diet, based on maize, soyabean and wheat, on the performance of laying hens and some indices of egg quality were studied for 8 weeks, using 65-week-old hens kept in cages. Albumen quality (albumen height and Haugh (1937) unit score) was improved, while yolk index and yolk colour score were not affected by dietar...

Unabsorbed yolk sacs are being investigated as a possible reservoir for internal Campylobacter and salmonellae contamination of processed poultry carcasses. However, it is unknown at what frequency that unabsorbed yolk sacs persist at the time of processing of broilers and spent breeders. Seven sets of 100 broiler carcasses (at 6 or 8 wk of age) were obtained from commercial processing plants. ...

There are still concerns over sperm quality when plant-based diluents used instead of animal-based semen extenders. Therefore, in our study we compared the effects one soybean lecithin-based (AndroMed®) and two egg yolk-based (BullXcell® Optidyl®) commercially available extenders on post-thaw vitro quality. Fifty ejaculates collected from ten bulls were aliquoted into three parts diluted with a...
