Irrespective the season, solitary beginning lambs was in fact usually heavier than twin regardless of the many years as the conveyed by imply weight of each delivery type of (Shape 5). 78 kilogram on delivery to just one.50 kg at ninety days, whereas in trip the difference reduced obvious in the delivery 0.33 kg, risen to 1.38 kilogram at the 3 months. This type of abilities have been in line with the ones from numerous experts (Afolayan ainsi que al 2006; Ekiz and Altinel 2006; Kuchtik and you can Dobes 2006; Merghem age tal 2011 and Yilmaz and Altin 2011).

The difference about mediocre each day acquire (Contour 6) between springtime solitary and you can dual birth reduced out-of 36.seven g/d at the 0-30 day so you’re able to twenty two.dos g/d during the 60-3 months, whereas the real difference dropped off 19.7 grams/d to help you 15.4 grams/d during trip at the same generation. As the quick reduced total of their average everyday get, solitary delivery average each and every day gain stayed greater than dual average day-after-day obtain throughout the months ranging from 0 to help you ninety days. Because the found in this analysis, quality out of single over twice delivery lambs could have been echte nüchterne Singles Dating Seite advertised by (Dekhili and you will Mahnane 2004 and Boussena ainsi que al 2013).

Effectation of new mom’s age

No matter what season, results indicated that the greatest lamb’s loads was basically primarily associated with the following generation “3 to 6 age” followed closely by the 3rd classification “six to help you nine decades”. During the springtime an average lambs’ loads was ten.six kilogram to the second age group and you can ten.dos kilogram toward 3rd age group and correspondingly nine.99 kilogram and nine.twenty-four kg during the fall (Profile eight and 8). It shopping for was in contract with that from (VanWyk ainsi que al 1993 and you can Este Fadili 2008) whom exhibited the key dictate of mom’s years on lamb’s weight, in addition, our efficiency indicated that lamb’s growth was also dependent on ewes decades (Shape nine and ten).

The results of the analysis of variance showed that differences between age groups were highly significant (p < 0.01). Examination of the means (Table 1) resulted in 4 groups (A, B, C, and D) highly different (p < 0. 01) according toTukey and Newman-keuls tests.

The first group A, birthing lambs with the highest weight included ewes aged from 3 to 9 years, regardless the season. Group C was mostly related to the age group less or equal to 3 years, whereas the lowest weights were always related to the age group more than 9 years. Indeed, this finding was also mentioned by Chopra and Acharya (1971) who showed that the intermediate age generally, gives birth to more vigorous lambs, whereas younger and older ewes give lighter lambs. The differences in lamb’s weight are explained by the fact that younger ewes (< 3 years) are still growing with bodies still developing, which leads them to share nutrients with their lambs, whereas ewes between 3 to 9 years have reached full growth and thus the lambs are provided with enough quantitative and qualitative nutrients. It should be also noted that the increasing growth in lambs' weight was related to the maternal behaviour; so lambs born from mothers aged of 3 to 9 years, which have already given several births, were much better supported than those born from first furrowing mothers aged less than 3 years. Allouche et al (2011) found similar results as ours for the same breed.
