This proves you to crossbreed cows are intimately significantly 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.

In order to ideal see the effect of new crossbreeding to the intimate precocity out of crossbreed pets, the latest AFC was reviewed predicated on: crossbreed sort of, battle out-of sire moms and dads (bull and you can inseminated local cows), hybridization top and you will stock facilities

The suggest age at first calving for everyone types come up with are ± days, symbolizing as much as 3 years (2 years 11 days 19 days ± 11 days 24 hours). Probably the most precocious heifers calved within this two years ( months). For fifty% out-of heifers, first calving was at months. The initial services were held an average of at the ± weeks ( so you can days).

The newest imply AFC of crossbreeds was less than men and women claimed one of many Zebu beneath the tropics during the over forty weeks reported in lots of studies ( Rahman mais aussi al., 2016 ; Tellah et al., 2015a , 2015b ; Bashir and you can El Zubeir, 2013 ; Sokouri et al., 2010 ; Bayemi mais aussi al., 2005 ). , 2015 ). Certain writers features claimed performance really next to our observation with the different crossbreeds inside Africa, regardless of cow breeds included in the newest try: 34 weeks one of the Montbeliard crossbreeds in Algeria ( Madani and Mouffok, 2008 ) and you will Morocco ( Srairi and you can Mousili, 2014 ), ± 0.43 months regarding Girolando crossbreed in the Benin ( Doko ainsi que al., 2012 ). It absolutely was an equivalent to the Holstein-Friesian hybrid cattle in Ethiopia from the 36.4 ± step 1.eight months, the latest Borgou and you will Lagunaire breeds from the 36.1 ± 6.31 days within the Benin ( Adamou-Ndiaye et al., 2003 ) plus in new Azawak Zebu from the 36.5 ± 4.10 and you may ± thirteen months during the Niger ( Achard and you can Chanono, 2006 , 1997 ).

The observation try more than people claimed of the Genzebu et al. (2016) among hybrid cows during the Kenya (twenty six.9 ± 5.cuatro and twenty-seven.0 ± 3.7 weeks). It was somewhat a lot better than the new findings because of the Ngodigha ainsi que al. (2009) off 31.seven ± 2.5 months one of crossbreeds (Holstein x Bunadji) during the Nigeria, Ben Salem et al. (2009) out of 31.7 ± cuatro.1 year in the Holstein into the Tunisia and you may Srairi and Mousili (2014) off 30 weeks inside the Montbeliard in Morocco. Certain type affairs for the AFC was analyzed so you’re able to attain the comments.

Among the many some other crossbreeding models recognized ( Table step one ), this new Fulani Zebu (FZ) inseminated having sperm off Montbeliard (MB x FZ) and you will Alps Brownish (Abdominal x FZ) provides lead probably the most precocious corssbreeds (basic calving in the 2 years) (5%). Whenever you are, the fresh new inseminations away from Fulani Zebu cattle toward semen regarding Holstein (HT x FZ) and you can out of Tarentaise (T x FZ) then the insemination regarding Gudali Zebu cows that have sperm from Montbeliard (MB x GZ) keeps produced the brand new precocious crossbreed cows.

The minimum is months and the siti incontri professioniste lesbiche restriction was months

Table 1: Years to start with calving (months) considering crossbreeding input milk products cattle farms in the region of Bobo-Dioulasso inside Burkina Faso

The research concerned about the newest reproduction tabs on twenty (20) hybrid cows through new interbreeding through the phony insemination anywhere between regional breed cattle (Gudali Zebu and Fulani Zebu) and you may amazing breed bulls (Holstein, Alps Brownish, Tarentaise, Montbeliard). This type of crossbreeds have been created between 1999 and 2010 and you will offered their very first calf ranging from 2002 and you can 2012 to your about three enhanced stock facilities from inside the metropolitan and residential district regions of Bobo-Dioulasso. Each one of these facilities enjoys from the 50 crossbreed cows when you look at the creation. The original ranch is located in a city, another 10 Kilometres aside at south get off while the third sixty Kilometer away on east get-off out-of Bobo-Dioulasso. Preliminary surveys ranging from within these areas assisted to select such about three farms which have a cattle register (temperature and you may artificial insemination monitoring sheet sets). Occurrences linked to private monitoring of animal reproduction instance calving schedules, times of first heats and you can inseminations was basically filed every day by the the cattlemen and inseminators. This new exploitation of them files made it possible to determine twenty (20) earliest calving’s corresponding to the first properties. These types of farms try described as the current presence of shed, a herd fitness keeping track of, a guided breeding means (mainly AI, having decreased a specified bull), the new concentrate supplies (cotton cake or cottonseed and industrial malt) regarding ration serving and you will intense delivery off silage and you will farming of the circumstances. The actual only real intent behind which operation form of is the development and you can product sales off by hand processed milk products, twice a day (early morning and evening). This new centers are served towards dogs to their go back regarding grazing along with the newest day at the milking big date.
