  • The Relationships among Breed, Milking Traits, Body and Udder Measurement in Hot Climate area in Yemen Mahfoudh .A.A.Al- Hered Faculty of Agriculture and veterinary – Thamar University-Yemen E-mail:dralhered100@yahoo.com 25-28 October 2010, Addis Ababa, Ethiopia
    • Cattle play important role in the economy of world wide countries. Great importance has been attached to the conformation traits of cattle. Technical developments have now made it possible to record most production characteristics objectively and the future conformation traits may be used primarily to aid the selection of characteristics important to the health and longevity of cattle and the amount of work required for their care (Ovesen, 1972).
    • Study of milk flow during milking can provide useful information for enhancing the efficiency of milking process avoiding some common mistakes, and protecting teat integrity and udder health (Tamburini et al., 2007). Rate of milk removal and time required to milk are of economic importance in relation to the amount of labor required per unit of milk yield (Markos and Touchberry,1970).
    • The differences in milk flow rates showed by the divergent breeds may reflect difference breeding goals among the breeds in the past, This includes traits aimed to maintaining or improving udder health(Walsh et al., 2007). Bulot (2006) reported some European dairy breed such as Montbeliarde and Brown Swiss had lower milk yield than Holstein.
    • Miller et al (1995) cited that cows with high milk yield have high milk flow rate and more susceptibility to mastitis.
    INTRODUCTION
  • INTRODUCTION
    • Increase milking speed or flow is associated with decrease milking labor time and labor is a significance expense in the harvest (Ral et al.,1990:Boettcher et al.,1998: Cecchinato et al.,2007), further more the above workers reproduces very slow milking cows can prolong the total time needed for milking and also disturb the milking routine. Teat and milkability traits are important managemental traits ,they affect the daily work of the farmer . The teat shape and placements can cause practical problems at milking (Ral et al.,1990). Ratore (1977) reported that cows with funnel shape teats produced 10.9-15.4% more milk than cows with cylindrical teats. In Turkey, Tilki et al (2005) found that Brown Swiss cows with bottle teats shape was lower in milk production than cows with cylindrical or funnel teat shape.
    • This study was carried out to determine the relationships among breeds, milking traits, body and udder measurements of Holstein-Friesian and Jersey cows in hot climate area in Yemen.
  • OBJECTIVE
    • This study was carried out to determine the relationships among breeds, milking traits, body and udder measurements of Holstein-Friesian and Jersey cows in hot climate area in Yemen.
  • MATERIALS AND METHODES
    • Study area :
    • The research was conducted in Al-Mara'e station-Al-Kadan 60Km East of Hodaidah province, Yemen. The area of study is located between 15 ْ 16 North latitude and 43 ْ 12 East longitude. The climate of this region is tropical sub humid, The annual rainfall ranges from 60-150mm ,the mean temperature reaches to highest 40 ْ C in July and august whereas the lower in January.
    • Collection of data :
    • Data were obtained from Al-Mara'e farm, 43 Holstein- Friesian and 27 Jersey cows were subjected to study and evaluation.
    • Experiment:
    • Cows were divided into 3 group according shape of teat. Measured of udders and teats were measured and recorded milk yield, milk flow for each cow were recorded weekly from 1-30 august 2006. The average milk flow was calculated as milk yield / milking time according to formula given by (Querengasser et al,2002).
    • Statistical analysis :
    • The data were obtained from this study were analyzed by general linear model (G.L.M) following the:
    • Y ijklm =µ+A i + B j + C k +D l + e ijklm .
    • The statistical significance for (the daily milk yield, milking time and milk rate flow according to teat shape were assessed by on way ANOVA. Comparison between group means were assessed by L.S.D. Phenotypic correlation between breeds, body and udder measurement with milking traits were determined by SPSS ver12.
  • Teats Shape Funnel Shape Flat Shape Cylindrical Shape
  • RESULT AND DISCUSSION
  • Table 1. Means and standard errors of milk traits, udder and body measurements
  • Table 2. Effect of breeds on all milk traits, body and udder measurement
  • Table 3. Effect of teat shape on milk traits (Means ±Standard errors)
  • Table 4 Phenotypic correlation of milking traits with breed , udder and body measurement
  • CONCLUTION
    • It could be concluded :
    • - The breed of cow significantly influence on milk yield and milking characteristics.
    • - The length and shape of teat effect on flow rate and daily milk yield.
    • - Cylindrical teat shape was higher than flat and funnel teat shape regarding daily milk yield but flat teat had the highest rate of milk flow.
  • SUGGESTION
    • It could be suggested :
    • Further research works is need to be conducted on local cow breeds to study milk traits.
    • Selection of cow breed based on adaptation can improve milk production.
    • The farmers should be trained to improve management farming. Attention should be paid to nutrition of animals.
