This proves you to definitely hybrid cows is actually intimately much more precocious than simply tropical cows ( Wassie ainsi que 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.

So you can ideal comprehend the effect of the new crossbreeding into the sexual precocity away from hybrid pet, the new AFC are reviewed centered on: hybrid types of, race from sire mothers (bull and you will inseminated local cattle), hybridization peak and you may stock facilities

The latest imply age initially calving for all types assembled try ± months, representing as much as 3 years (2 years eleven days 19 days ± 11 months twenty four hours). The essential precocious heifers calved within a couple of years ( months). Having fifty% out-of heifers, very first calving was at weeks. The first services took place normally in the ± weeks ( so you’re able to months).

The latest indicate AFC of crossbreeds try lower than those people said one of several Zebu within the tropics within over 40 months reported in a lot of education ( Rahman et al., 2016 ; Tellah et al., 2015a , 2015b ; Bashir and you will Este Zubeir, 2013 ; Sokouri ainsi que al., 2010 ; Bayemi ainsi que al., 2005 ). , 2015 ). Particular people features stated results very near to all of our observation on various other crossbreeds inside Africa, despite cow types utilized in brand new try: 34 months one of the Montbeliard crossbreeds inside the Algeria ( Madani and you may Mouffok, 2008 ) and you can Morocco ( Srairi and you can Mousili, 2014 ), ± 0.43 days regarding Girolando hybrid in Benin ( Doko et al., 2012 ). It was an equivalent with the Holstein-Friesian crossbreed cattle from inside the Ethiopia during the thirty-six.cuatro ± step one.7 weeks, the latest Borgou and Lagunaire types from the 36.step 1 ± six.31 months inside Benin ( Adamou-Ndiaye ainsi que al., 2003 ) and in the new Azawak Zebu within thirty six.5 ± cuatro.ten and you will ± thirteen months for the Niger ( Achard and Chanono, 2006 , 1997 ).

All of our observation is actually higher than people stated from the Genzebu ainsi que al. (2016) certainly hybrid cattle when you look at the Kenya (26.nine ± 5.4 and twenty seven.0 ± step three.7 days). It had been some better than the fresh new findings of the Ngodigha ainsi que al. (2009) from 30.eight ± 2.5 weeks among crossbreeds (Holstein x Bunadji) in Nigeria, Ben Salem et al. (2009) away from 30.eight ± cuatro.1 year inside the Holstein in Tunisia and you may Srairi and you may Mousili (2014) away from 30 weeks during the Montbeliard into the Morocco. Particular adaptation points with the AFC was basically reviewed so you’re able to achieve the comments.

Among the more crossbreeding items known ( Dining table step 1 ), the latest Fulani Zebu (FZ) inseminated with sperm out of Montbeliard (MB x FZ) and you may siti gratuiti incontri politici Alps Brownish (Abdominal x FZ) has delivered many precocious corssbreeds (earliest calving within two years) (5%). If you find yourself, the brand new inseminations of Fulani Zebu cattle on the sperm out-of Holstein (HT x FZ) and you will from Tarentaise (T x FZ) then the insemination out of Gudali Zebu cows that have sperm away from Montbeliard (MB x GZ) keeps introduced the newest precocious hybrid cattle.

Minimal was months additionally the limit was months

Desk step one: Age initially calving (months) predicated on crossbreeding input milk products cows facilities in your community away from Bobo-Dioulasso for the Burkina Faso

The research focused on new breeding tabs on twenty (20) hybrid cattle through brand new interbreeding through the fake insemination anywhere between regional breed cattle (Gudali Zebu and you may Fulani Zebu) and unique reproduce bulls (Holstein, Alps Brown, Tarentaise, Montbeliard). These crossbreeds was indeed created ranging from 1999 and you will 2010 and gave their very first calf ranging from 2002 and 2012 to the three increased stock farms into the metropolitan and you can suburban areas of Bobo-Dioulasso. Each one of these facilities provides on the 50 crossbreed cows into the creation. The initial ranch is situated in an urban area, the following 10 Kilometer aside at the southern exit and third 60 Kilometer away in the eastern get off regarding Bobo-Dioulasso. Preliminary surveys anywhere between during these section aided to pick such three farms having a livestock check in (temperatures and you will artificial insemination monitoring sheet sets). Occurrences pertaining to private track of animal reproduction for example calving schedules, schedules of the earliest warms and you may inseminations was submitted each and every day by the the fresh new cattlemen in addition to inseminators. New exploitation of these documents managed to get you are able to to choose twenty (20) earliest calving’s comparable to the initial qualities. These facilities was characterized by the current presence of forgotten, a great herd health monitoring, a led reproduction mode (mostly AI, getting diminished a specified bull), the new concentrate provides (cotton cake or cottonseed and industrial malt) from the ration serving and extreme distribution out-of silage and you can agricultural by things. The sole function of so it process variety of ‘s the design and sale out-of by hand processed milk products, twice daily (early morning and you may nights). New centers try served to your pet on their get back out-of grazing as well as in brand new day at the milking go out.
