Background Low-density lipoproteins (LDL) is known to protect boar sperm during freezing–thawing, but little information is known about the effects of LDL extracted from different avian egg yolks on post-thaw boar semen quality. The purpose of this study was to compare and analyze the effects of LDL at various concentrations and different species on boar sperm quality after freezing–thawing. Ma...

This study aims to analyze the Break-Even Point of Backyard laying hens business in Sidenreng Rappang Regency. research was conducted Bulo Village, backyard farm. from February April 2020. In this used a case study, results are not generalized. The total profit earned by these people's farm is IDR 137,717,244. For price 37,000 eggs, it will reach BEP at 1,617,723/ egg, 1,436,727,272 with egg 88...

This study investigated correlations between egg quality indicators to identify external traits predict internal using non-destructive and convenient measurements. Thirteen indicators, including Haugh unit, albumen height, eggshell breaking strength, thickness, color (CIE L*, CIE a*, b*), reflectivity value, weight, length, width, shape index, yolk color, were i...

Abstract Around the world, declines in mean size of nesting sea turtles have been reported with concerns a concomitant decrease reproductive output populations. Here, we explore this possibility using long-term observations green ( Chelonia mydas ) at Aldabra Atoll, Seychelles. Based on > 4500 individual measurements over 21 years (1996–2016), found curved carapace length females declined by...

Although some studies have identified parasites in green turtles (Chelonia mydas), little is known about the morphology of helminth eggs feces these animals. The aim this study was to morphologically characterize recovered coproparasitological exams by sedimentation and analyze their relationship with species during necropsy juvenile specimens C. mydas. Four different egg morphotypes were found...

Morphometric parameters are analyzed and systematized of parasitic nematodes the species Trichuris sylvilagi Tiner, 1950, obtained from Lepus europaeus (Pallas, 1778). The following suggested for exact identification female T. nematodes: sizes body, its anterior posterior parts, width body at connection esophagus intestine, specific location vesicular cuticular protrusions vulva. Five metric es...

The objective of this research was to investigate the body measurements female Arabian chickens during laying phase. study utilized a sample 95 chickens, aged 94 weeks, which were housed in battery cages and for egg production. Direct taken on each chicken, with variables including weight, head circumference, beak length, comb height, neck back wing chest width, depth, upper thigh lower shank d...

to study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (hps). the stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...

this experiment was conducted to investigate the effects of different levels of l-carnitine on productive performance, egg quality and blood parameters in laying hens. forty-eight hy-line w-36 egg layers were weighed at 90 weeks of age and randomly allocated into 16 cages (three hens per cage). four dietary treatments were prepared by supplementing l-carnitine (0, 50, 100 and 150 mg/kg of diet)...

an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...
