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 most useful see the effect of the latest crossbreeding on the intimate precocity regarding crossbreed dogs, this new AFC was examined based on: crossbreed style of, race from sire mothers (bull and you may inseminated local cows), hybridization top and you may stock facilities

The newest mean ages in the beginning calving for everybody breeds come up with is actually ± months, symbolizing everything 3 years (2 yrs 11 months 19 weeks ± eleven days twenty four hours). More precocious heifers calved inside two years ( months). Having fifty% off heifers, earliest calving was at days. The original characteristics happened typically within ± days ( so you’re able to months).

The new suggest AFC of your own crossbreeds is actually less than those people advertised among Zebu in tropics at over 40 weeks advertised a number of degree ( Rahman mais aussi al., 2016 ; Tellah et al., 2015a , 2015b ; Bashir and Este Zubeir, 2013 ; Sokouri mais aussi al., 2010 ; Bayemi et al., 2005 ). , 2015 ). Some writers provides advertised overall performance most close to our observance on the more crossbreeds in the Africa, in spite of cow breeds used in brand new try out: 34 days among the Montbeliard crossbreeds when you look at the Algeria ( Madani and Mouffok, 2008 ) and you can Morocco ( Srairi and you may Mousili, 2014 ), ± 0.43 weeks on Girolando hybrid for the Benin ( Doko mais aussi al., 2012 ). It was a comparable to the Holstein-Friesian crossbreed cattle into the Ethiopia from the 36.cuatro ± 1.eight days, the newest Borgou and you may Lagunaire breeds within thirty six.step 1 ± 6.31 days for the Benin ( Adamou-Ndiaye ainsi que al., 2003 ) as well as in brand new Azawak Zebu during the thirty-six.5 ± 4.10 and ± thirteen days during the Niger ( Achard and Chanono, 2006 , 1997 ).

Our very own observance is greater than those people said of the Genzebu et al. (2016) certainly hybrid cattle for the Kenya (26.9 ± 5.4 and you may twenty-seven.0 ± step three.eight days). It actually was somewhat a lot better than the findings from the Ngodigha et al. (2009) away from 30.seven ± 2.5 days certainly one of crossbreeds (Holstein x Bunadji) inside the Nigeria, Ben Salem ainsi que al. (2009) from 29.eight ± cuatro.1 year when you look at the Holstein during the Tunisia and you may Srairi and you may Mousili (2014) from 29 days inside Montbeliard when you look at the Morocco. Some version facts for the AFC was basically analyzed so you can achieve the statements.

One of many various other crossbreeding models recognized ( Table step one ), the latest Fulani Zebu (FZ) inseminated that have sperm away from Montbeliard (MB x FZ) and you will Alps Brown (Ab x FZ) has delivered the quintessential precocious corssbreeds (basic calving during the 2 years) (5%). If you are, this new inseminations from Fulani Zebu cattle on sperm from Holstein (HT x FZ) and you can away from Tarentaise (T x FZ) then your insemination off Gudali Zebu cows with sperm away from Montbeliard (MB x GZ) features produced the new precocious crossbreed cows.

The minimum is weeks as well as the restrict is weeks

Dining table 1: Years initially calving (months) predicated on crossbreeding type in dairy cattle facilities in the region out-of Bobo-Dioulasso within the Burkina Faso

The analysis focused on the fresh new breeding tabs on twenty (20) crossbreed cows resulting from new interbreeding through the artificial insemination ranging from local breed cows (Gudali Zebu and Fulani Zebu) and you can unique reproduce bulls (Holstein, Alps Brownish, Tarentaise, Montbeliard). This type of crossbreeds were created anywhere between 1999 and you can 2010 and you will provided their very first calf anywhere between 2002 and 2012 on around three enhanced inventory farms into the metropolitan and you will residential district areas of Bobo-Dioulasso. All these farms provides from the sitios de citas musulmanas fifty crossbreed cattle inside production. The first farm is found in an urban area, the following 10 Kilometer away at the south leave additionally the 3rd sixty Kilometres aside in the eastern leave out-of Bobo-Dioulasso. Initial surveys anywhere between during these parts assisted to select these three facilities having a cattle sign in (heat and you will artificial insemination overseeing sheets). Occurrences pertaining to private tabs on animal breeding such as for example calving times, dates of very first heating and inseminations have been recorded each day from the the fresh new cattlemen therefore the inseminators. The newest exploitation ones records managed to make it you are able to to decide twenty (20) first calving’s comparable to the first attributes. These farms was characterized by the existence of missing, a beneficial herd fitness overseeing, a led breeding function (mostly AI, for decreased a specified bull), the fresh new concentrate offers (cotton cake or cottonseed and commercial malt) on the ration feeding and you will rigorous shipment from silage and you may farming by the affairs. Really the only function of it process style of ‘s the creation and you will purchases out-of manually processed milk products, two times a day (day and you will nights). The brand new focuses try supported towards the dogs to their go back away from grazing and in brand new morning from the milking date.
