effect of bataine and sulphate supplement on wool and milk characteristics and lambs performance in naine ewes
تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولSupplementing metabolizable protein to ewes during late gestation: II. Effects on ewe lamb performance and reproductive efficiency.
The objective of the current study was to determine the effects of maternal MP intake in isocaloric diets during late gestation on female offspring growth from birth to breeding and measure reproductive performance of those offspring in their first breeding season. In yr 1, maternal dietary treatments were applied at d 100 of gestation, were similar in total energy, and contained 60MP1, 60% of ...
متن کاملSupplementing metabolizable protein to ewes during late gestation: I. Effects on ewe performance and offspring performance from birth to weaning.
We hypothesized that a maternal diet greater in MP during the last third of gestation would yield improved offspring growth due to enhanced placental or mammary gland function. Our objective was to determine how MP intake during late gestation affected ewe and offspring performance from birth to weaning in ewes fed diets similar in total energy. In yr 1, maternal dietary treatments were applied...
متن کاملEffects of Energy and Protein Levels of Maternal Diets at Late Gestation on Growth, Health and Performance of Goat Kids
A study was conducted to evaluate the effects of energy and protein levels of maternal diets on growth, some blood parameters, health, and performance of baby goat kids at first month of life. On 95 d after successful mating, 28 synchronized singleton pregnant Sistani goats were randomly allocated to four treatments including 1) low protein and low energy (LPLE), 2) high protein and low energy ...
متن کاملAltering ewe nutrition in late gestation: I. The impact on pre- and postpartum ewe performance.
The present study was conducted to examine the effects of offering a single diet rationed to 80% (80% ME), 100% (100% ME), or 120% (120% ME) of recommended ME requirements from d 119 of gestation to lambing, with concurrent changes in other dietary nutrients. The effects on pre- and postpartum ewe performance, including estimated milk yield and milk fatty acid concentrations, were monitored. Si...
