This shows that crossbreed cows is intimately alot more precocious than just warm cows ( Wassie ainsi que 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.
The latest suggest many years in the beginning calving for everyone types build was ± days, symbolizing up to 36 months (24 months 11 days 19 months ± eleven months a day). Minimal is actually weeks therefore the restrict was days. The quintessential precocious heifers calved in this 2 years ( months). Having 50% out-of heifers, first calving is at days. The original characteristics took place on average within ± weeks ( so you’re able to weeks).
The fresh new mean AFC of the crossbreeds was below those individuals stated one of many Zebu within the tropics in the more than forty months advertised in lot of degree ( Rahman mais aussi al., 2016 ; Tellah ainsi que al., 2015a , 2015b ; Bashir and you will El Zubeir, 2013 ; Sokouri et al., 2010 ; Bayemi et al., 2005 ). , 2015 ). Particular authors provides reported abilities most next to all of our observance toward some other crossbreeds within the Africa, despite cow types utilized in the try out: 34 months one of several Montbeliard crossbreeds inside the Algeria ( Madani and you can Mouffok, 2008 ) and you may Morocco ( Srairi and Mousili, 2014 ), ± 0.43 days regarding the Girolando hybrid from inside the Benin ( Doko mais aussi al., 2012 ). It absolutely was an equivalent toward Holstein-Friesian crossbreed cattle inside the Ethiopia within thirty six.4 ± 1.7 days, the fresh new Borgou and you can Lagunaire breeds at thirty six.step 1 ± 6.30 months in Benin ( Adamou-Ndiaye ainsi que al., 2003 ) and also in this new Azawak Zebu on thirty six.5 ± 4.10 and you will ± 13 months when you look at the Niger ( Achard and you may Chanono, 2006 , 1997 ).
Our very own observance was more than those reported of the Genzebu et al. (2016) one of hybrid cattle in Kenya (twenty-six.9 ± 5.cuatro and you can 27.0 ± step 3.eight days). It was quite better than the new observations by the Ngodigha et al. (2009) out of 29.7 ± dos.5 weeks among crossbreeds (Holstein x Bunadji) in Nigeria, Ben Salem et al. (2009) off 31.eight ± 4.12 months inside Holstein within the Tunisia and you may Srairi and you may Mousili (2014) regarding 31 weeks in the Montbeliard during the Morocco.
One of several different crossbreeding brands identified ( Table 1 ), brand new Fulani Zebu (FZ) inseminated having semen from Montbeliard (MB x FZ) and you can Alps Brown (Abdominal x FZ) possess lead the essential precocious corssbreeds (earliest calving on 2 yrs) (5%). If you’re, this new inseminations away from Fulani Zebu cattle to your sperm of Holstein (HT x FZ) and away from Tarentaise (T x FZ) then your insemination away from Gudali Zebu cows having sperm off Montbeliard (MB x GZ) has lead the fresh precocious crossbreed cattle.
Some version affairs on the AFC was basically assessed in order to attain the statements
Dining table 1: Years at first calving (months) predicated on crossbreeding enter in milk products cows facilities in your neighborhood from Bobo-Dioulasso into the Burkina Faso
So you’re able to ideal see the aftereffect of the crossbreeding on the intimate precocity out of crossbreed pet, the fresh AFC was examined according to: crossbreed particular, competition out of sire moms and dads (bull and you may inseminated local cattle), hybridization top and you will stock farms
The study worried about the breeding track of twenty (20) hybrid cattle resulting from the brand new interbreeding through the phony insemination anywhere between local reproduce cows (Gudali Zebu and you may Fulani Zebu) and amazing reproduce bulls (Holstein, Alps Brownish, Tarentaise, Montbeliard). These types of crossbreeds was basically born ranging from 1999 and you will 2010 and offered their basic calf anywhere between 2002 and you can 2012 towards the about three increased stock farms within the urban and you can residential district regions of Bobo-Dioulasso. Each one of these farms provides regarding fifty hybrid cows during the design. The first farm is situated in a city, next ten Kilometres aside within south get off and the third sixty Kilometer out on east hop out off Bobo-Dioulasso. First surveys ranging from within these elements helped to choose such around three facilities which have a cattle sign in (temperatures and you may phony insemination keeping track of sheet sets). Events connected with individual monitoring of animal reproduction eg calving times, Adult datings dating apps times of one’s earliest heats and you will inseminations had been registered day-after-day of the the fresh new cattlemen additionally the inseminators. The fresh exploitation ones data files managed to make it you can easily to determine twenty (20) earliest calving’s comparable to the first properties. These farms is actually characterized by the current presence of missing, good herd health monitoring, a led reproduction form (primarily AI, to possess insufficient a selected bull), the newest focus provides (pure cotton pie otherwise cottonseed and you can industrial malt) regarding ration giving and you can rigorous shipments regarding silage and you can agricultural because of the factors. The only purpose of it process sorts of is the manufacturing and you may deals out-of yourself processed milk, twice a day (day and you will night). The newest focuses was offered on pets on the get back from grazing as well as in the morning from the milking go out.
