This shows you to crossbreed cows is intimately much more precocious than warm cows ( 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.

To help you most useful see the effect of the new crossbreeding to your intimate precocity regarding hybrid dogs, new AFC is actually analyzed centered on: crossbreed variety of, race out-of sire parents (bull and you can inseminated local cows), hybridization peak and you can inventory farms

The indicate years at first calving for everyone breeds come up with is actually ± weeks, representing whenever three years (two years 11 days 19 days ± eleven weeks a day). The quintessential precocious heifers calved within a couple of years ( months). For 50% regarding heifers, basic calving is at days. The first features happened typically from the ± days ( to help you days).

The latest indicate AFC of the crossbreeds are less than men and women advertised among the many Zebu according to the tropics in the more 40 weeks reported in several training ( Rahman ainsi que al., 2016 ; Tellah ainsi que al., 2015a , 2015b ; Bashir and you may Este Zubeir, 2013 ; Sokouri mais aussi al., 2010 ; Bayemi mais aussi al., 2005 ). , 2015 ). Particular authors have advertised overall performance most close to the observance for the some other crossbreeds in the Africa, despite cow breeds found in new test: 34 months among the many Montbeliard crossbreeds for the Algeria ( Madani and Mouffok, 2008 ) and you may Morocco ( Srairi and Mousili, 2014 ), ± 0.43 months on Girolando crossbreed into the Benin ( Doko ainsi que al., 2012 ). It actually was the same to your Holstein-Friesian hybrid cows within the Ethiopia during the thirty six.cuatro ± 1.7 days, the new Borgou and you may Lagunaire breeds at 36.step 1 ± 6.30 days when you look at the Benin ( Adamou-Ndiaye mais aussi al., 2003 ) and in this new Azawak Zebu at the thirty-six.5 ± 4.ten and ± 13 months inside the Niger ( Achard and you may Chanono, 2006 , 1997 ).

All of our observation are greater than people said from the Genzebu et al. (2016) among hybrid cows from inside the Kenya (26.9 ± 5.cuatro and you will twenty-seven.0 ± step three.7 months). It was quite a lot better than the brand new observations by the Ngodigha mais aussi al. (2009) off 30.seven ± 2.5 days among crossbreeds (Holstein x Bunadji) inside the Nigeria, Ben Salem ainsi que al. (2009) from 31.7 ± 4.1 year into the Holstein for the Tunisia and you will Srairi and you will Mousili (2014) out of 31 months inside the Montbeliard from inside the Morocco. Some version situations for the AFC was in fact reviewed in order to attain the comments.

Among the many various other crossbreeding sizes understood ( Table step 1 ), the latest Fulani Zebu (FZ) inseminated that have sperm from Montbeliard (MB x FZ) and you will Alps Brown (Ab x FZ) features put by far the most precocious corssbreeds (earliest calving at a couple of years) (5%). While, the brand new inseminations off Fulani Zebu cattle to your semen out of Holstein (HT x FZ) and you can from Tarentaise (T x FZ) then insemination regarding Gudali Zebu cattle that have semen away from Montbeliard (MB x GZ) keeps put the fresh new precocious crossbreed cows.

The minimum are days while the limitation are days

Desk 1: Age to start with calving (months) according to crossbreeding input milk cows farms in the area out-of Bobo-Dioulasso during the Burkina Faso

The analysis worried about the brand new breeding monitoring of twenty (20) crossbreed cattle through the newest interbreeding from the phony insemination ranging from local reproduce cows (Gudali Zebu and you will Fulani Zebu) and exotic breed bulls (Holstein, Alps Brownish, Tarentaise, Montbeliard). These types of crossbreeds was indeed created anywhere between 1999 and you will 2010 and offered the first calf between 2002 and 2012 into about three improved inventory facilities in the urban and you may residential district aspects of Bobo-Dioulasso. Each one of these facilities enjoys regarding the 50 hybrid cattle for the manufacturing. The original ranch is situated in a city, the second ten Kilometres aside on south get off additionally the 3rd sixty Km aside within eastern leave away from Bobo-Dioulasso. First surveys between in these elements aided to pick this type of three farms having a livestock sign in (temperature and you will phony insemination keeping track of sheets). Incidents about personal monitoring of animal breeding eg calving schedules, times of your very first heating and you can inseminations was recorded daily from the new cattlemen together with inseminators. This new exploitation of those records siti incontri sculacciata e solletico managed to make it you can to choose twenty (20) very first calving’s add up to the original attributes. Such farms are described as the presence of destroyed, an effective herd health monitoring, a led reproduction function (generally AI, to own lack of a selected bull), the newest focus provides (cotton fiber cake otherwise cottonseed and you may industrial malt) in the ration serving and you can intense delivery from silage and you can agricultural of the points. The only real aim of so it process method of is the creation and revenue out-of by hand canned milk, twice daily (day and you may nights). The new centers is actually supported with the animals on their get back away from grazing plus new morning within milking big date.
