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 new suggest years to start with calving for everyone types built try ± months, representing whenever three-years (couple of years 11 days 19 days ± 11 days day). Minimal is actually weeks while the restriction was weeks. One particular precocious heifers calved in this couple of years ( months). To possess fifty% of heifers, basic calving was at days. The original features occurred typically https://datingranking.net/dating/ at the ± months ( in order to days).

The fresh mean AFC of crossbreeds try below those claimed among the many Zebu in tropics within over 40 days reported in several education ( Rahman ainsi que al., 2016 ; Tellah et al., 2015a , 2015b ; Bashir and El Zubeir, 2013 ; Sokouri ainsi que al., 2010 ; Bayemi et al., 2005 ). , 2015 ). Particular writers features said abilities most next to our observance into the various other crossbreeds for the Africa, in spite of cow types used in new check out: 34 days one of several Montbeliard crossbreeds in Algeria ( Madani and you can Mouffok, 2008 ) and you may Morocco ( Srairi and you may Mousili, 2014 ), ± 0.43 days about Girolando hybrid into the Benin ( Doko mais aussi al., 2012 ). It absolutely was a comparable into Holstein-Friesian crossbreed cattle within the Ethiopia at 36.cuatro ± step one.7 weeks, the latest Borgou and you may Lagunaire types on 36.step 1 ± six.29 days inside the Benin ( Adamou-Ndiaye mais aussi al., 2003 ) plus in the latest Azawak Zebu from the 36.5 ± 4.ten and you will ± 13 months within the Niger ( Achard and you may Chanono, 2006 , 1997 ).

The observation are higher than people claimed by the Genzebu et al. (2016) certainly one of hybrid cows inside Kenya (twenty six.9 ± 5.4 and twenty seven.0 ± step three.7 weeks). It absolutely was slightly better than new observations from the Ngodigha et al. (2009) out-of 29.eight ± dos.5 days certainly crossbreeds (Holstein x Bunadji) in the Nigeria, Ben Salem et al. (2009) out-of 30.eight ± 4.12 months during the Holstein into the Tunisia and Srairi and you can Mousili (2014) of 30 weeks for the Montbeliard from inside the Morocco.

One of several other crossbreeding designs known ( Dining table 1 ), the new Fulani Zebu (FZ) inseminated with semen off Montbeliard (MB x FZ) and you will Alps Brown (Ab x FZ) possess produced the quintessential precocious corssbreeds (earliest calving from the two years) (5%). If you are, new inseminations off Fulani Zebu cows to the semen regarding Holstein (HT x FZ) and off Tarentaise (T x FZ) then the insemination away from Gudali Zebu cows that have semen out of Montbeliard (MB x GZ) has lead new precocious crossbreed cows.

Certain adaptation points of this AFC had been examined in order to achieve the statements

Table step one: Age to start with calving (months) based on crossbreeding type in milk cattle facilities in your community out of Bobo-Dioulasso inside the Burkina Faso

So you’re able to finest see the aftereffect of this new crossbreeding to the sexual precocity out of crossbreed pet, the brand new AFC are examined predicated on: crossbreed style of, competition away from sire mothers (bull and you will inseminated regional cattle), hybridization peak and stock farms

The study worried about brand new breeding monitoring of twenty (20) hybrid cattle resulting from the fresh interbreeding from artificial insemination between regional breed cows (Gudali Zebu and you can Fulani Zebu) and you will exotic breed bulls (Holstein, Alps Brownish, Tarentaise, Montbeliard). These types of crossbreeds was created ranging from 1999 and you will 2010 and you will provided the basic calf ranging from 2002 and you can 2012 on about three increased inventory farms within the urban and residential district aspects of Bobo-Dioulasso. Each one of these facilities has actually throughout the 50 crossbreed cattle when you look at the design. The initial ranch is found in a city, next 10 Kilometres away on southern log off and the third 60 Kilometres aside from the eastern exit away from Bobo-Dioulasso. Initial surveys between during these portion aided to select these types of three farms with a cattle register (temperatures and you will artificial insemination monitoring sheets). Events associated with personal track of creature breeding including calving schedules, times of your first warms and you may inseminations was indeed submitted every single day because of the the fresh cattlemen therefore the inseminators. The newest exploitation of those data files made it you can to determine twenty (20) earliest calving’s equal to the initial services. These types of farms was described as the existence of forgotten, a good herd health monitoring, a led breeding means (primarily AI, to possess shortage of a selected bull), brand new concentrate provides (cotton fiber pie or cottonseed and you can commercial malt) on the ration serving and you can intense shipping of silage and agricultural of the facts. The only purpose of that it procedure type of is the creation and you may sale off manually canned whole milk, twice daily (early morning and you may evening). This new concentrates try served into the pet to their come back of grazing as well as in brand new day at milking big date.
