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.

To help you top comprehend the effect of the fresh crossbreeding towards the intimate precocity out-of hybrid pets, the AFC is examined according to: hybrid sorts of, race from sire mothers (bull and you can inseminated local cows), hybridization top and you can inventory facilities

The latest mean decades to start with calving for all breeds put together try ± days, representing up to three-years (couple of years eleven months 19 months ± 11 days 1 day). Probably the most precocious heifers calved within a couple of years ( months). To own 50% out of heifers, very first calving was at weeks. The first features were held typically in the ± months ( to days).

The fresh mean AFC of one’s crossbreeds was below men and women stated one of many Zebu beneath the tropics in the more than forty months said in a lot of studies ( Rahman et al., 2016 ; Tellah ainsi que al., 2015a , 2015b ; Bashir and you can Este Zubeir, 2013 ; Sokouri mais aussi al., 2010 ; Bayemi ainsi que al., 2005 ). , 2015 ). Some authors has actually claimed results extremely close to all of our observance towards the more crossbreeds from inside the Africa, in spite of cow breeds utilized in the brand new test: 34 months among Montbeliard crossbreeds in the Algeria ( Madani and you will Mouffok, 2008 ) and Morocco ( Srairi and Mousili, 2014 ), ± 0.43 months regarding the Girolando hybrid inside the Benin ( Doko et al., 2012 ). It had been the same into the Holstein-Friesian hybrid cows in Ethiopia from the 36.4 ± 1.7 days, the brand new Borgou and Lagunaire types at thirty-six.step one ± 6.30 months when you look at the Benin ( Adamou-Ndiaye mais aussi al., 2003 ) and also in the fresh Azawak Zebu during the thirty six.5 ± cuatro.ten and you will ± thirteen weeks inside Niger ( Achard and you will Chanono, 2006 , 1997 ).

Our observation try higher than people said by the Genzebu mais aussi al. (2016) certainly one of hybrid cows in the Kenya (twenty-six.nine ± 5.cuatro and you will twenty-seven.0 ± weeks). It absolutely was slightly a lot better than this new findings by Ngodigha mais aussi al. (2009) from 29.7 ± dos.5 weeks certainly one of crossbreeds (Holstein x Bunadji) in Nigeria, Ben Salem ainsi que al. (2009) of 30.eight ± year within the Holstein when you look at the Tunisia and you may Srairi and you can Mousili (2014) of 29 months into the Montbeliard when you look at the Morocco. Certain adaptation affairs in the AFC was assessed in order to achieve the comments.

Among other crossbreeding systems understood ( Dining table 1 ), brand new Fulani Zebu (FZ) inseminated having semen from Montbeliard (MB x FZ) and Alps Brown (Ab x FZ) provides lead by far the most precocious corssbreeds (basic calving within 24 months) (5%). If you find yourself, the new inseminations of Fulani Zebu cattle with the sperm of Holstein (HT x FZ) and you can of Tarentaise (T x FZ) then the insemination out of Gudali Zebu cattle that have sperm out of Montbeliard (MB x GZ) keeps put brand new precocious hybrid cattle.

Minimal is actually months additionally the restrict was weeks

Dining table step 1: Age in the beginning calving (months) considering crossbreeding enter in milk products cattle facilities in the region out of Bobo-Dioulasso inside Burkina Faso

The research concerned about the breeding track of twenty (20) crossbreed cows resulting from the latest interbreeding from the phony insemination ranging from regional reproduce cattle (Gudali Zebu and you can Fulani Zebu) and you will unique reproduce bulls (Holstein, Alps Brown, Tarentaise, Montbeliard). These types of crossbreeds were produced ranging from 1999 and you may 2010 and you may offered the first calf between 2002 and you will 2012 to your three increased inventory facilities when you look at the metropolitan and suburban areas of Bobo-Dioulasso. Each of these facilities enjoys about fifty hybrid cattle inside the development. The original ranch is situated in an urban area, next ten Kilometres away within south get off and third sixty Kilometres aside in the eastern get-off from Bobo-Dioulasso. Initial studies ranging from throughout these section assisted to choose such three facilities that have a livestock check in (temperatures and you may artificial insemination overseeing sheet sets). Events associated with private track of creature reproduction such as calving schedules, schedules of your own earliest warms and inseminations was in fact recorded each and every day by the fresh new cattlemen while the inseminators. The brand new exploitation of them data managed to make it you’ll to decide twenty (20) very first calving’s equal to the initial qualities. Such farms was characterized by the current presence of destroyed, good herd wellness monitoring, a led breeding setting (mostly AI, to own decreased a selected bull), the new concentrate offers (pure cotton cake otherwise cottonseed and you can commercial malt) regarding ration serving and you may extreme delivery regarding silage and you may agricultural by activities. Really the only reason for which procedure method of ‘s the design and you may business out-of manually processed whole milk, two times a day (morning and you can night). This new centers are served to your dogs on the get back out-of grazing and in the newest morning during the milking big date.
