Honde kan baie goed in die aand sien,as honde in aand jag sonder spotlight werk hul op reuk en gehoor en sig, n spotlight verblind hul vir n rukkie as hul uit lig hardloop en dan moet hul oe eers weer aanpas by die donker en dan sien hul weer goed. het al gesien dat n hond in donker hardloop en prooi vang en met hom in die bek terugkom. Dink net op volmaan sien jakkalse ook baie beter en was my sukses al minder as met donkermaan.

HI

HET AL GESIEN JOU BESTE HOND IN DIE AAND IS NIE NOODWENDIG JOU BESTE HOND IN DIE DAG NIE. PARTY HONDE JAG BETER IN DIE AAND AS ANDER EN ANDERS OM. EK HOU MAAR VAN IN DIE DAG JAG.

Hounddog..
Kan jy dalk vir my beter s? waar die naam Boerwindhond vandaan kom?

[HOUNDDOG]

RACER

SOOS VAN DIE ANDER MANNE REEDS GESE HET GLO EK OOK DIE NAAM BOERHOND HET ONTSTAAN OMDAT MEESTAL BOERE DIE HONDE GEBRUIK HET OM TE JAG EN OM OOK DIE HOND DAN TE KAN ONDERSKEI VAN BAAN EN SKOU WINDHONDE.

[skalla]

Nee, hy hardloop nie vinnig genoeg om te jag nie!! Ek het hom al laat hardloop...

[Foxhound]

Middag kerels,
Ek weet nie baie van honde af nie, maar 'n klomp honde kenners, of sogenaamde honde kenners se vir my dat swart pigment onontbeerlik is by windhonde en veral hulle toonnaels en kussinkies onner die voete dan hou hulle voete beter. Ek weet hulle moet opgetrekte tone he, anners hou hulle voete nie. Ek boer hier in die boesmanland, droee harde veld. My honne loop 3 keer per week so tussen 25 en 35 km per dag as my jagter uitgaan, somtyds met die voet, somtyds met die perd en kere met die fiets. Eks van mening dat jou enjin vinnig of sterk kan wees, maar as jy 'n papwiel het, dan los die jakkals jou agter. Wat se die kenners/telers?

[Foxhound]

Hallo Skalla

Het ook al van daardie stelling gehoor so deur die lyne maar nou ja, dan moet n ou seker maar in 'n rigting in teel soos jou voorkeure ens, dit vat net soms bai lank om dan jou perfekte hond te teel, vir die tipe jag wat ek doen hardloop die honde nie heel dag nie, maar ons doen ons ding en nogasl doeltreffend, ek dink die man wat jou die beste gaan kan beantwoord is Greyhound, hy is ook op die forum, en di eerste honde is syne

As jy na van die foto's kyk wat al geplaas is sal jy seker jou voorkeure vind

Groete
Foxhound

P.S: Greyhound gee ons bikki jou mening van die pigment ens van die voete en die gehardheid daarvan asb?

Ek het met skaaphonde geboer & geteel en het een maal `n hond gehad met pienk kussinkies, neus. Seer voete was aan die orde van die dag, totdat een van my ou werkers eendag `n mengsel aan gemaak het wat met 2x se gebruik die probleem opgelos het. Meng ou swart olie met petrol, as die hond se voete seer is word dit daar in gedruk, moenie vra hoe of hoekom nie, want ek weet nie maar vir my het dit gewerk.

By skaaphonde kry jy party maal `n blou oog, met `n wit ooglid wat dan maar swaar kry in die karoo son. Hier het `n vrou wat saam met my kompetisies gedoen het die raad van " Vital Kelp" pille gegee, jy koop dit sommer by Shoprite of Spar, enige winkel. Dit bevat 'sea weed' wat die pigment laat groei, ek weet nie of dit vir die voete sal help nie, maar dit laat die neus en ooglede se swart pigment groei.

Foxhound,
Ek hou van jou hond. Sy lyk bietjie fyner en dis waarvan ek hou. Swaarder honde se voete hou ook nie, maar dis my beskeie mening. Swaarder honde na my mening sukkel ook om draaijakkalse vinnig te vang.

Goeie More Manne!

Lanklaas.baie welkom mnr! Vra vir greyhound om ook vir jou n paar pics te wys. Stephan ook n goeie roep. Luukse bedryf. Ek persoonlik geniet dit regtig baie. Nou besig om n 75%SABW25%BAANHOND werpsel groot te maak. Ek eksperimenteer maar bietjie!

[Greyhound.Racer]

Middag Kamakasi,
Dit klink intresant hou ons op hoogte asb..
Ek het nog 2 van my kruising hondjies oor hulle is nou 5maaande oud en baie stoud.
Hulle is haalf Baanhond haalf Boerhond..

Groete

[KAMAKASI]

Die kleintjies is nou bliksems stout!!! Maar besluit om al 9 groot te maak en te kyk wat maak hul,weens die feit dat hul performance honde is kyk ek nie krieties na bouvorm nie,hoewel ek dit belangrik ag! My focus en voorliefde is en sal altyd by my suiwer SABWde bly! Soos al voorheen gese:?Defferent horses for different courses!? Die teef is 50%/50% en reun suiwer SABW,sy naam is kamakasi! sal nou en dan inloer en laat weet wat gaan aan!

[Greyhound.Racer]

Goeie naand almal.
Ek het op een van Nitro se jonger broer af gekom na 'n paar oproepe om seeker temaak dat dit wel so is, ek is baie bly dat ek 'n broer van hom raak geloop het want Nitro is n Stunning hond sal al my Baanhonde verruil vir Nitro. Ek het my Boerhond teef na hom toe gevat vir dek sal maar sien of hy kan gooi..
Sal more n foto neem van hom en op sit..
Baie dankie Mr. Stephan vir jou inligting..

Kamamasi hoe ganit met jou hondjies??

Goeie dag aan almal..
Hier is so bietjie Windhond info hoop julle gan die like..

Some people are fascinated by the horsepower, cornering dynamics and top speed of a fast car, the climb speed and maneuverability of a fighter plane..

The figures are based on the average 30kg greyhound, at the peak of fitness and obviously injury free.

Energy Use
In the first 7.5 seconds of a 30-second race, a greyhound metabolises high energy creatine and glycogen stores in its muscles without the need for oxygen.

It uses the creatine energy base during the first 3.5 seconds acceleration phase to the first bend of a standard circle track.

In fact, a greyhound expends half of its total energy used in a race for this acceleration stage.

However, surprisingly greyhounds and even racing sprint horses performing for less than one minute expend in a race only about 6% of their total energy intake required each day to meet the exercise needs in training.

Acceleration Speed
At maximum acceleration, a greyhound reaches a full speed of 70 kmh within 30 metres or six strides from the boxes, traveling at almost 20 metres per second for the first 250 metres of a race.

The only other animal that can accelerate faster over a short distance is a cheetah that can reach speeds of 109 kmh over 3-4 strides from a standing start.

The greyhound can maintain an average speed of 16.45 metres per second over a 500 metre race, decreasing to around 14.6 metres per second as it crosses the finish line.

A thoroughbred racehorse can achieve a maximum speed of around 49 kmh or 13.6 metres per second.

An elite human sprinter can reach 40kmh in a 10 second sprint race at an all out speed of 11 metres per second.

The muscles of a greyhound generate 75-80% of their power from anaerobic metabolic pathways during a 30 second race.

In distance races, or coursing trials in excess of 40 seconds duration, 80% of the total energy in the final half of the race or gallop is metabolised using oxygen.

The Heart
In a racing greyhound, the heart output increases from about 200mL per kg body weight per minute at rest to over 1000mL per kg at the full gallop. A greyhound circulates up to 15 litres of blood around its body, or half its own body weight in a 30 second-race.

A racing greyhound circulates its entire blood volume between 4-5 times during a 30 second gallop.

These figures equate to a greyhound pumping its entire blood volume of around 3.4 litres up to 4-5 times around its body during a 30 second gallop. A greyhound's heart weight ranges from 1.18 to 1.73% of body weight, or 270 grams to 519 grams for a 30kg greyhound, which is higher than an elite racehorse at 1.0-1.3% of its body weight.

Other breeds of dogs have a heart weight equal to 0.77% of their body weight, compared to 0.5% for humans.

An average 70kg human athlete has a heart size similar to a 30kg greyhound, but the greyhound's heart delivers blood at almost twice the rate, beating at 310-340 beats/minute at the gallop, compared to humans at 170.210 beats/minute.

Blood Volume
A fit greyhound has the highest blood volume of any athlete, relative to its body size, with blood contributing 11.4%, compared to 10.5% for a racehorse, 9.5% for a human sprint athlete and 7.2% for a normal pet dog.

A greyhound has around 35 x 1012 red blood cells in its body, producing around 5 million replacement red cells per second in its bone marrow and spleen.

A fit greyhound has about 3 litres of blood consisting of around 2 litres red cells, or about 6.6% of its body weight or a PCV of 60% of blood volume. A racehorse has a blood volume of around 55 litres, but a PCV of around 40% when fit, or 4.4% of its body weight.

Track Contact
At a gallop, a racing greyhound is only touching the track surface for 25% of its stride distance, and during the remainder of the stride, it is suspended above the ground until the next limb hits the ground.

Up the straight, a greyhound carries 2.26 times its body weight on the weight bearing front limb at each stride, increasing to 5 times (or roughly 150kg) in downward weight force on its left inside front limb when leaning over around a sharp bend on the track.

A greyhound has a stride length of around 5 metres making 4 strides per second as it accelerates from the traps, decreasing to 3.25 strides per second up the home straight, with each limb touching the ground for about 0.11 seconds.

The forelimbs have a flight distance (off the ground) of 1.23 metres, and the rear legs 2.45 metres or double the distance.

Wrist/Bone Joints
The wrist joint bones on the front limbs sustain pressure of 500psi or 20,000 newtons per square cm when cornering at the gallop.

The wrist and lower limb structures withstand up to 150kg of downward pressure when galloping around a corner, which is created by the centrifugal force in proportion to the speed of the greyhound and the radius of the track circle.

This sideways force is imposed on the greyhound's front limb on the second stride into the corner and if the track surface is unstable or shears, the outward flinging force causes increased sideways pressure on the joint, which can result in injury to the wrist.

Respiratory & Blood Pressure Dynamics
A greyhound draws in 60-90 litres of air in 50-90 breaths in a 30-second gallop, extracting 1500 mLs of oxygen from the air to metabolise the energy in its muscles.

During the gallop, the blood pressure in the lung arteries increases from 7 mm mercury pressure units at rest, to 40 units at the gallop, similar to the pressure peak in a human athlete, but only one third of the maximum pressure in a racehorse's lung artery, which reaches 120 mm mercury pressure, or roughly 2.1 psi of pressure.

A greyhound produces around 100Kcals or 100,000 watts of waste heat energy during a 30 second race, sufficient to bring 600mL of tap water to the boil in around 2 minutes.

After a race, the gut function is restored over a 30 minute period to digest food, but the immune system is depressed for 30-120 minutes after a hard gallop.

Loading stress placed on the limb bones is repaired over a 7-10 day period after a race.
