This shows you to definitely hybrid cows are intimately a great deal more precocious than exotic cattle ( Wassie et al

Data extracted from the analysis of herd records were entered in Excel. The descriptive statistical analysis of the age at first calving (calculation of frequencies, means, standard deviations, minimum and maximum) was made with the XLSTAT software (6.1.9 release). These parameters were analyzed by ANOVA and the results were compared using the Newman-Keuls test. Differences were considered significant for p < 0.05.

The fresh new imply years at first calving for all breeds assembled is ± months, symbolizing everything three years (2 yrs 11 weeks 19 months ± eleven days 24 hours). The minimum is days therefore the limit was months. More precocious heifers calved within two years ( months). To own 50% out of heifers, first calving is at months. The initial attributes took place typically at the ± days ( to months).

The latest suggest AFC of your crossbreeds is less than the individuals said one of several Zebu under the tropics during the more than 40 months claimed a number of training ( Rahman et al., 2016 ; Tellah ainsi que al., 2015a , 2015b ; Bashir and you can El Zubeir, 2013 ; Sokouri ainsi que al., 2010 ; Bayemi ainsi que al., 2005 ). , 2015 ). Some authors enjoys said abilities most next to our observation to your various other crossbreeds inside Africa, in spite of cow types included in the latest try: 34 days one of many Montbeliard crossbreeds within the Algeria ( Madani and Mouffok, 2008 ) and you may Morocco ( Srairi and you may Mousili, Russian dating app 2014 ), ± 0.43 months about Girolando hybrid in Benin ( Doko ainsi que al., 2012 ). It had been the same toward Holstein-Friesian hybrid cattle into the Ethiopia during the 36.4 ± step 1.eight months, the fresh Borgou and you can Lagunaire breeds at the thirty-six.step 1 ± six.30 months in Benin ( Adamou-Ndiaye ainsi que al., 2003 ) as well as in the newest Azawak Zebu within thirty six.5 ± cuatro.10 and you can ± 13 weeks in the Niger ( Achard and you can Chanono, 2006 , 1997 ).

All of our observance try greater than the individuals said because of the Genzebu ainsi que al. (2016) certainly hybrid cows in the Kenya (twenty-six.nine ± 5.cuatro and you may twenty-seven.0 ± 3.7 months). It had been some much better than the latest observations by the Ngodigha mais aussi al. (2009) away from 30.7 ± dos.5 months among crossbreeds (Holstein x Bunadji) within the Nigeria, Ben Salem mais aussi al. (2009) regarding 29.7 ± 4.12 months in the Holstein for the Tunisia and you may Srairi and you will Mousili (2014) from 30 days inside Montbeliard in the Morocco.

One of the other crossbreeding products understood ( Desk 1 ), brand new Fulani Zebu (FZ) inseminated that have sperm out of Montbeliard (MB x FZ) and you will Alps Brown (Abdominal x FZ) enjoys delivered more precocious corssbreeds (earliest calving during the 24 months) (5%). While you are, the fresh new inseminations out of Fulani Zebu cattle on the semen of Holstein (HT x FZ) and out of Tarentaise (T x FZ) then the insemination away from Gudali Zebu cattle that have sperm from Montbeliard (MB x GZ) features delivered the latest precocious crossbreed cattle.

Certain adaptation products associated with AFC was analyzed in order to achieve the comments

Table step 1: Ages in the beginning calving (months) according to crossbreeding enter in whole milk cattle facilities in the region out-of Bobo-Dioulasso within the Burkina Faso

So you can most useful understand the aftereffect of the newest crossbreeding to your sexual precocity off hybrid pet, the AFC was reviewed considering: crossbreed particular, competition from sire parents (bull and you can inseminated regional cattle), hybridization level and you can inventory farms

The analysis worried about this new breeding track of twenty (20) hybrid cattle resulting from the brand new interbreeding through the phony insemination ranging from regional reproduce cows (Gudali Zebu and you will Fulani Zebu) and you may unique breed bulls (Holstein, Alps Brown, Tarentaise, Montbeliard). Such crossbreeds was in fact born ranging from 1999 and you will 2010 and you will gave the basic calf anywhere between 2002 and you can 2012 to the three improved stock farms when you look at the metropolitan and you can residential district areas of Bobo-Dioulasso. Every one of these farms have from the 50 hybrid cows from inside the manufacturing. The original ranch is situated in a city, the next ten Km away at the southern get off together with third 60 Kilometer out at the east hop out out of Bobo-Dioulasso. Original studies between within these components helped to choose these types of about three facilities which have a cattle register (temperature and artificial insemination monitoring sheets). Events regarding private track of animal reproduction instance calving dates, dates of one’s basic warms and you may inseminations had been recorded day-after-day because of the the fresh new cattlemen and the inseminators. The fresh new exploitation of these files caused it to be it is possible to to choose twenty (20) very first calving’s equal to the first features. This type of farms are characterized by the presence of lost, a good herd health overseeing, a led reproduction means (primarily AI, getting insufficient a specified bull), the fresh new concentrate offers (thread pie otherwise cottonseed and you will industrial malt) regarding ration eating and rigorous distribution from silage and you will agricultural by things. The only real purpose of that it procedure style of is the development and you may income off by hand processed milk products, twice a day (morning and night). The latest centers try supported to the animals on their get back regarding grazing as well as in the brand new early morning from the milking day.
