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 greatest comprehend the effect of the crossbreeding towards the sexual precocity off crossbreed pet, brand new AFC are assessed predicated on: crossbreed types of, competition out-of sire parents (bull and inseminated regional cattle), hybridization level and you can inventory facilities

This new suggest age to start with calving for everyone breeds make try ± days, representing just as much as 3 years (2 years eleven weeks 19 days ± 11 months 1 day). The absolute most precocious heifers calved in this 2 years ( months). For 50% of heifers, first calving was at days. The initial features happened typically at ± weeks ( to weeks).

New indicate AFC of your own crossbreeds try less than those individuals claimed among the many Zebu under the tropics at the more 40 days advertised in a lot of degree ( Rahman et al., 2016 ; Tellah mais aussi al., 2015a , 2015b ; Bashir and El Zubeir, 2013 ; Sokouri et al., 2010 ; Bayemi et al., 2005 ). , 2015 ). Particular article writers has actually stated efficiency extremely near to our observance towards the more crossbreeds in the Africa, notwithstanding cow breeds found in the fresh experiment: 34 months among the many Montbeliard crossbreeds inside Algeria ( Madani and Mouffok, 2008 ) and you will Morocco ( Srairi and you will Mousili, 2014 ), ± 0.43 months on Girolando crossbreed inside the Benin ( Doko ainsi que al., 2012 ). It was a similar for the Holstein-Friesian crossbreed cattle into the Ethiopia from the 36.4 ± 1.seven months, the new Borgou and Lagunaire breeds on thirty six.1 ± six.29 days when you look at the Benin ( Adamou-Ndiaye et al., 2003 ) as well as in brand new Azawak Zebu within thirty six.5 ± cuatro.ten and you will ± thirteen months during the Niger ( Achard and you can Chanono, 2006 , 1997 ).

Our very own observance are more than those claimed by Genzebu ainsi que al. (2016) among crossbreed cows inside Kenya (twenty six.nine ± 5.4 and you will twenty seven.0 ± 3.eight months). It actually was a little a lot better than brand new findings of the Ngodigha mais aussi al. (2009) away from 29.seven ± dos.5 days certainly crossbreeds (Holstein x Bunadji) in the Nigeria, Ben Salem et al. (2009) out-of 30.eight ± 4.12 months from inside the Holstein inside the Tunisia and you will Srairi and you will Mousili (2014) regarding 29 months during the Montbeliard in the Morocco. Some version issues regarding the AFC was in fact analyzed in order to attain the comments.

Among the many additional crossbreeding sizes identified ( Table step one ), this new Fulani Zebu (FZ) inseminated with sperm from Montbeliard (MB x FZ) and you may Alps Brownish (Ab x FZ) enjoys put more precocious corssbreeds (basic calving during the 2 years) (5%). While, the brand new inseminations out-of Fulani Zebu cows to the sperm of Holstein (HT x FZ) and you can out-of Tarentaise (T x FZ) then the insemination from Gudali Zebu cattle which have sperm from Montbeliard (MB x GZ) has produced the precocious hybrid cows.

Minimal are weeks plus the limitation are days

Dining table step one: Years at first calving (months) predicated on crossbreeding input milk products cows facilities in your neighborhood regarding Bobo-Dioulasso in Burkina Faso

The study concerned about the newest reproduction tabs on twenty (20) hybrid cows through the interbreeding from the phony insemination between local breed cows (Gudali Zebu and Fulani Zebu) and you may exotic reproduce bulls (Holstein, Alps Brownish, Tarentaise, Montbeliard). These crossbreeds were produced between 1999 and you may 2010 and gave its earliest calf anywhere between 2002 and you may 2012 on the three improved stock farms in metropolitan and you will suburban aspects of Bobo-Dioulasso. Each one of these farms enjoys on the 50 crossbreed cattle inside the manufacturing. The initial farm is located in an urban area, the following 10 Kilometres aside at the southern area get-off as well as the third sixty Kilometer away during the east hop out out of Bobo-Dioulasso. Initial studies between within these section aided to pick such https://datingranking.net/fr/sites-de-rencontre-noirs/ around three facilities which have a livestock register (heat and you may artificial insemination monitoring sheet sets). Events related to individual track of animal reproduction such calving times, dates of one’s first warms and you can inseminations were filed daily by new cattlemen and also the inseminators. This new exploitation of them data files managed to make it it is possible to to determine twenty (20) first calving’s add up to the original services. These types of farms are characterized by the existence of missing, an excellent herd wellness monitoring, a led reproduction function (generally AI, having decreased a designated bull), the latest concentrate offers (pure cotton cake or cottonseed and industrial malt) from the ration feeding and you can extreme delivery of silage and agricultural of the points. The only real reason for it process method of is the manufacturing and product sales out-of by hand canned dairy, two times a day (day and you will nights). The fresh concentrates are offered towards pets on their get back out of grazing plus the new morning within milking big date.
