Estudo dos cortes da carcaça de cordeiros Santa Inês puros e cruzas Santa Inês com Texel, Ile de France e Bergamácia
(Sociedade Brasileira de Zootecnia, 2004-04-01)
Foram utilizados 103 cordeiros, machos e fêmeas, Santa Inês puros (SS) e cruzas Santa Inês com Texel (TS), Ile de France (FS) e Bergamácia (BS), confinados em gaiolas individuais. Os cordeiros foram abatidos em quatro ...
Modeling metabolizable energy utilization in broiler breeder pullets
(2003-03-01)
The objective of this study was to determine models for ME requirements for broiler breeder pullets using the factorial method. The influence of the temperature on maintenance ME requirements was determined by experiments ...
Energy Requirements for Maintenance and Growth of Male Saanen Goat Kids
(Asian-australasian Assoc Animal Production Soc, 2014-09-01)
The aim of study was to determine the energy requirements for maintenance and growth of forty-one Saanen, intact male kids with initial body weight (BW) of 5.12 +/- 0.19 kg. The baseline (BL) group consisted of eight kids ...
Protein and energy requirements of castrated male Saanen goats
(Elsevier B.V., 2015-01-01)
A comparative slaughter trial was conducted to determine the energy and protein requirements for growth of castrated male Saanen goats weighing from 20 to 35 kg body weight (BW). Regarding maintenance requirements, 36 ...
Protein levels for heat-exposed broilers: Performance, nutrients digestibility, and energy and protein metabolism
(2007-06-11)
Heat stress causes significant economic losses on broilers production due to poorer performance and carcass quality. Considering that protein has the highest heat increment among nutrients, it has been suggested that protein ...

The effect of pre-slaughter stressors on physiological indicators and meat quality traits on Merino lambs
(Elsevier Science, 2013-04)
Merino lambs of 90 days of mean age (standard deviation - s.d. - 6 days) and 22.0. kg of mean live weight (s.d. 2.7. kg) were used to explore the effects of pre-slaughter stressors on physiological characteristics and meat ...
