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 indicate decades to start with calving for everybody types build is actually ± weeks, symbolizing approximately 36 months (24 months eleven weeks 19 days ± 11 weeks twenty four hours). The minimum try weeks and limit is actually weeks. The absolute most precocious heifers calved within two years ( months). To have 50% away from heifers, earliest calving is at weeks. The original services were held an average of within ± weeks ( so you’re able to days).
The fresh new suggest AFC of the crossbreeds was below people claimed among Zebu in tropics in the more than forty weeks stated in several knowledge ( Rahman mais aussi al., 2016 ; Tellah mais aussi al., 2015a , 2015b ; Bashir and Este Zubeir, 2013 ; Sokouri et al., 2010 ; Bayemi ainsi que al., 2005 ). , 2015 ). Particular writers keeps claimed performance extremely near to all of our observation on the various other crossbreeds in Africa, notwithstanding cow types found in the new test: 34 days among Montbeliard crossbreeds within the Algeria ( Madani and you can Mouffok, 2008 ) and you can Morocco ( Srairi and you can Mousili, 2014 ), ± 0.43 days on the Girolando crossbreed from inside the Benin ( Doko mais aussi al., 2012 ). It had been an identical to your Holstein-Friesian crossbreed cattle in Ethiopia in the thirty-six.cuatro ± 1.7 days, brand new Borgou and you will Lagunaire types at the thirty six.step one ± 6.31 days inside Benin ( Adamou-Ndiaye mais aussi al., 2003 ) plus in the new Azawak Zebu within 36.5 ± cuatro.10 and ± thirteen weeks in Niger ( Achard and you will Chanono, 2006 , 1997 ).
Our observation was higher than men and women said because of the Genzebu mais aussi al. (2016) certainly crossbreed cows inside Kenya (twenty six.nine ± 5.cuatro and you can twenty-seven.0 ± step three.7 days). It absolutely was a bit a lot better than the fresh findings of the Ngodigha ainsi que al. (2009) out of 29.seven ± 2.5 months certainly crossbreeds (Holstein x Bunadji) during the Nigeria, Ben Salem et al. (2009) of 30.7 free Filipino dating sites ± 4.1 year for the Holstein inside Tunisia and you will Srairi and Mousili (2014) off 31 months in the Montbeliard from inside the Morocco.
Among other crossbreeding versions understood ( Dining table 1 ), the brand new Fulani Zebu (FZ) inseminated which have semen out-of Montbeliard (MB x FZ) and you can Alps Brownish (Ab x FZ) has produced the essential precocious corssbreeds (basic calving from the 24 months) (5%). If you find yourself, the inseminations out-of Fulani Zebu cows to the sperm away from Holstein (HT x FZ) and you can of Tarentaise (T x FZ) then insemination off Gudali Zebu cows that have semen from Montbeliard (MB x GZ) enjoys introduced the fresh precocious crossbreed cows.
Specific type things from the AFC was basically examined in order to achieve the statements
Dining table step 1: Age initially calving (months) predicated on crossbreeding type in milk cattle farms in the region off Bobo-Dioulasso during the Burkina Faso
In order to top see the effectation of the crossbreeding towards the intimate precocity out of crossbreed dogs, the fresh new AFC is actually analyzed based on: crossbreed variety of, race of sire moms and dads (bull and you will inseminated regional cattle), hybridization top and inventory facilities
The study concerned about the brand new reproduction monitoring of twenty (20) hybrid cattle resulting from the new interbreeding from the phony insemination ranging from local breed cows (Gudali Zebu and you can Fulani Zebu) and unique reproduce bulls (Holstein, Alps Brown, Tarentaise, Montbeliard). These crossbreeds was in fact created anywhere between 1999 and you may 2010 and you may provided its very first calf ranging from 2002 and you can 2012 with the about three improved inventory farms in the metropolitan and you can suburban regions of Bobo-Dioulasso. All these farms have in the fifty crossbreed cows inside manufacturing. The first ranch is located in a city, another ten Kilometres aside on southern exit while the 3rd 60 Km away within eastern leave out-of Bobo-Dioulasso. Initial studies anywhere between during these parts aided to select such about three farms having a livestock register (temperatures and artificial insemination monitoring sheets). Events associated with individual monitoring of creature reproduction such calving schedules, schedules of first heats and you may inseminations were submitted everyday of the the new cattlemen additionally the inseminators. The new exploitation of these documents caused it to be you can easily to choose twenty (20) earliest calving’s corresponding to the first characteristics. Such farms is actually described as the presence of destroyed, good herd wellness keeping track of, a led reproduction mode (mainly AI, getting decreased a specified bull), brand new concentrate provides (cotton cake otherwise cottonseed and you may commercial malt) from the ration eating and you will extreme shipment of silage and you will farming because of the factors. The actual only real reason for this procedure types of is the development and purchases from by hand processed dairy, two times a day (day and nights). The brand new focuses try supported with the animals on their go back regarding grazing plus the newest day during the milking day.
