Pelibuey ewes synchronized with progestagens and mated with rams from Dorper and Katahdin breeds under feedlot conditions: ewe production and lamb growth during the pre-weaning period. The aim of this study was to evaluate the productivity of Pelibuey Pb ewes lambed over a period of four years , which were synchronized with progesterone and PMSG and mated to Pb, Dorper Dr , and Katahdin Ka rams under confinement. Additionally, birth and weaning weight, and pre-weaning daily weight gain GDP of lambs born from these crosses were also evaluated. A linear model including the effects of year of lambing block , sire breed, type of lambing, sex and their interactions, was used to analyze birth and weaning weight, and GDP of lambs.

Information about Page Insights Data. Continue Reading. By: Dr Alejandro Ferrer On the topic of buying-selling track stallions and eternal discussion There are 3 main components: 1. They are governed by a local and national association that registration activities are carried out through a registrar technician who belongs to that association.
In the subject of the registered, you can arrange for 10 animals based on your criterion, but finally the technician will define, that you will not be able to register all; for example for cases of prognatism or testicular hypoplasia.
And you can finally register six or seven of the ten. In my experience as a breeder after 20 years in the katahdin breed only 3 out of ten specimens were outstanding for the purpose HINT.
And what did clue mean? That they had no structural defects not even mild and good weight gains. As a breeding foot producer you must fulfill the task of always selecting better animals or you will be off the market. Currently you must produce a copy of excellent morphotype and weight gains when weaning and postweaning so that it is reflected in your offspring with positive numbers. There will definitely be within the track specimens, copies that do not transmit these productive characteristics to their offspring.
However, the percentage of specimens that will transmit these characteristics to their offspring will be higher when the selection work is higher in this group of animals by breeders. Similarly, there will be specimens that do not meet track characteristics and inherit their offspring economic characteristics associated with profitability.
And this is where the problem begins economically between the buyer and seller, those selection years have a different cost from the specimens that are not subjected to this type of selection.
And there will be registration animals of different commercial value. Here you have to approach producers who have absolute seriousness, years of work, who have all the necessary information that is required at the time of purchase. If there is no data to show, let alone genetic selection guarantee. And there are many complaints in which they express they were surprised.
However, several aspects are given due to lack of knowledge or training mainly, new producers buy without knowledge and are easy prey to opportunistic. Surely you'll get more economical. Ask for all the data you think is necessary: Type of birth, birth weight, weaning weight, weight days, current weight at the time of purchase, obviously have family registration.
If all this data is not, the seller surely won't be a trusted producer. Don't get to ask for a lamb believing they will give it cheaper, genetics COST. An adaptation period is necessary before the ride.
Try to avoid selecting just because he's son of the champion, they complain a lot about this form of buying-selling but the buyer is the one who fosters it the most. Weight gain features are medium to highly inherited, select for these features.
What you buy at fairs is prepared with a very good food to express its characteristics, it is not worth complaining that race or that activity does not serve, if you do not know the minimum of handling you must carry with that acquired stud.
Define goals, make a small analysis of what your productive shortcomings are and buy what you need, not what's fashionable. Of course NOT, they are economic characteristics associated with productive specimens.
But for example Dorper with a worldwide defined racial standard doesn't present the problem so much. Meat fitness breeds likewise, the main feature is meat production, simple must be meat. In the katahdin race I think that is where the problem is most, that if they must be bigger, longer and less meat, all races have their fashion, but definitely the market takes them to an economically profitable plane, you cannot produce copies of a lot of size and a lot of weight because it's hard for you to keep them.
The current era demand to produce to the fullest with acceptable costs and that same need will cause breeders to raise that type of animal or will be destined to disappear In the end the 3 components of this theme we have to do the things that correspond to us and prevent only a buy-sale where the main factor is just to achieve an economic gain without any ethics and professionalism For the future and sake of sheep activity that each item does things as they should be.

Reproductor Pelibuey Pelibuey Player Translated. What factors determine the price of our animals or because we have no standard fixed prices.? We are constantly asked about availability, cost information and a base price of a stud or belly of our genetic project With pleasure and with the sincerity we like to reflect I inform you that for the moment we do not have animals available They ask me How does a male stud come out?.. How much the female s?.. Selling lambs? Like a lot of those females like the picture?..
One more or less as soon as they come out?.. Like the couple? And so we can follow the variants in their questions I really appreciate all that interest and that's why I will make this post How much does it cost me to produce bellies and stallions according to my genetic project and the protocol we set to offer for sale only the best or more viable for reproduction? We have to keep in mind as Breeders try to offer the best for their reproduction.. From its planning in the empadre, its conception, development, development monitoring, conformation, morphology, correct in its previous and later members, phenotype and all but all the work that involves selecting the best specimens of each litter That standard of quality we set out and it's what we do Selling lambs or lambs 5 months or less?
To analyze! Our principle is to develop its entirety maturity.. Is it expensive to do this Well what production is currently cheap and with quality in it? Expensive inputs Hand more and scarce And the time spent in it So your animals are expensive? That is dictated by the animal itself in its development and final evolution How much will it be worth Depends on whether it was included in any of our own selection categories Top - Excellent - Regular They are not put up for sale as players.
We know that we set out an out-of-ordinary parenting method and we will be criticized for it but our genetic project is totally focused on producing animals as productive as possible! Since it will be the business card of our work and above all your future business as sheep ocultors We don't sell for auction, offer or excess production What's left in pens for replacement or for sale is the best of the litter That is why once our selection process is finished, animals will be offered for sale and with their due description where all the information of the animal in question will be given Productive parameters Let's hope this serves you something to remove doubts and above all understand us how we work to produce productive sheep A la espera.
