This proves one crossbreed cattle is sexually alot more precocious than just warm cattle ( Wassie mais aussi 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 brand new mean age to start with calving for all types make was ± months, representing everything three-years (two years 11 months 19 weeks ± 11 months 24 hours). Minimal was weeks and the limitation are months. By far the most precocious heifers calved within couple of years ( months). To have fifty% out of heifers, first calving is at days. The initial attributes occurred typically at the ± days ( so you’re able to days).

The fresh new indicate AFC of your own crossbreeds try lower than those individuals claimed one of the Zebu in tropics at over forty weeks said in lot of training ( Rahman et al., 2016 ; Tellah ainsi que al., 2015a , 2015b ; Bashir and you may Este Zubeir, 2013 ; Sokouri mais aussi al., 2010 ; Bayemi et al., 2005 ). , 2015 ). Specific article writers have reported show really next to our very own observation for the other crossbreeds inside Africa, regardless of cow types included in the new test: 34 weeks one of many Montbeliard crossbreeds in the Algeria ( Madani and you will Mouffok, 2008 ) and you will Morocco ( Srairi and you can Mousili, 2014 ), ± 0.43 weeks throughout the Girolando hybrid in the Benin ( Doko et al., 2012 ). It was the same for the Holstein-Friesian crossbreed cows inside the Ethiopia in the 36.cuatro ± step 1.7 months, the new Borgou and Lagunaire types on thirty-six.step one ± six.30 months inside Benin ( Adamou-Ndiaye mais aussi al., 2003 ) along with the Azawak Zebu during the 36.5 ± cuatro.10 and you will ± 13 months during the Niger ( Achard and Chanono, 2006 , 1997 ).

All of our observance is more than those people said because of the Genzebu ainsi que al. (2016) certainly hybrid cattle from inside the Kenya (twenty-six.9 ± 5.4 and you can 27.0 ± step 3.eight days). It actually was quite better than the latest findings of the Ngodigha mais aussi al. (2009) out of 30.7 ± 2.5 weeks one of crossbreeds (Holstein x Bunadji) inside the Nigeria, Ben Salem et al. (2009) out of 31.seven ± 4.12 months into the Holstein for the Tunisia and you will Srairi and you will Mousili (2014) out of 31 months during the Montbeliard inside the Morocco.

Among the many other crossbreeding items identified ( Desk step 1 ), new Fulani Zebu (FZ) inseminated with semen regarding Montbeliard (MB x FZ) and you will Alps Brown (Ab x FZ) possess delivered probably the most precocious corssbreeds (earliest calving at couple of years) (5%). If you are, the inseminations from Fulani Zebu cows into sperm from Holstein (HT x FZ) and you can of Tarentaise (T x FZ) then insemination of Gudali Zebu cattle which have semen regarding Montbeliard (MB x GZ) enjoys produced the brand new precocious hybrid cattle.

Certain adaptation facts of AFC were analyzed to help you attain the comments

Table step 1: Decades initially calving (months) predicated on crossbreeding enter in dairy cattle facilities in the area away from Bobo-Dioulasso inside Burkina Faso

So you’re able to better comprehend the effect of brand new crossbreeding towards the sexual precocity away from hybrid animals, the new AFC is actually assessed considering: crossbreed type, battle out of sire moms and dads (bull and inseminated local cows), hybridization peak and you may stock facilities

The research concerned about the fresh new breeding track of twenty (20) crossbreed cattle because of the fresh new interbreeding from the artificial insemination between regional breed cattle (Gudali Zebu and you can Fulani Zebu) and you may exotic reproduce bulls (Holstein, Alps Brownish, Tarentaise, Montbeliard). These crossbreeds have been created anywhere between 1999 and 2010 and you will provided their earliest calf between 2002 and you may 2012 to the about three increased stock farms when you look at the urban and you may suburban regions of Bobo-Dioulasso. Each one of these facilities have regarding fifty crossbreed cows inside the design. The first ranch is situated in an urban area, the following 10 Kilometres away in the southern exit plus the third 60 Kilometer aside from the eastern leave out of Bobo-Dioulasso. First studies between on these areas aided to choose such around three farms with a livestock sign in (temperatures and you may phony insemination monitoring sheet sets). Incidents linked to individual tabs on animal breeding such as for example calving dates, schedules of basic warms and inseminations was in fact submitted daily by the the brand new cattlemen therefore the inseminators. The exploitation of those documents caused it to be you can easily to choose twenty (20) basic calving’s corresponding to the first features. These farms is characterized by the presence of shed, an excellent herd wellness overseeing, a led breeding means (generally AI, getting shortage of a selected bull), new focus supplies (cotton pie or cottonseed and you may industrial malt) regarding the ration eating and you may rigorous shipment out-of silage and you can agricultural by the activities. Really the only function of which procedure particular is the creation and you may business off by hand processed milk, twice daily (day and you will night). The fresh centers try supported towards the pet on their get back out-of grazing as well as in the fresh day at milking go out.
