Eficiência reprodutiva e produtiva em ovelhas Corriedale brancas e naturalmente...
Costa, Pablo Tavares; Mendonça, Gilson de; Vaz, Ricardo Zambarda; Brum, Larissa Picada; Bragagnollo, Maurício Prestes; Vieira, Thiago PereiraO objetivo deste trabalho foi avaliar a influência do fenótipo na eficiência reprodutiva de ovelhas e o desempenho dos cordeiros do nascimento ao desmame. Foram utilizadas 111 ovelhas adultas da raça Corriedale (54 naturalmente coloridas e 57 brancas), mantidas em pastagem natural, suplementadas no terço final da gestação e pastoreadas em pastagem natural melhorada após o parto. Os acasalamentos foram realizado...
Body mass index at calving on performance and efficiency of Zebu cow herds
Vaz, Ricardo Zambarda; Cérdotes, Liliane; Pacheco, Rangel Fernandes; Sartori, Dayana Bernardi; Lucas, Jeniffer Danielle; Agner, Hilda Solange SouzaThis study examines the impact of the body mass index (BMI) at calving on the development and postpartum efficiency of cows of Zebu origin. The study involved 87 cows and their calves [pure Nellore (N) or predominant Nellore composition in a cross with Charolais (C) (3/4N1/4C and 5/8N3/8C)]. The mothers were grouped into classes according to their BMI at calving, namely, ‘small’, ‘moderate’ and ‘large’. Body ma...
Supplementation and productive and reproductive performance of primiparous cows...
Lobato, José Fernando Piva; Cadó, Lucas Munareto; Poli, Cèsar Henrique Espirito Candal; Jacondino, Luiza Rodegheri; Souza, Carolina Balbé de Oliveira deThis study aimed at evaluating the reproductive performance of 42 primiparous crossbred Angus cows at 24-25 months of age fed or not a supplement at 0.8% of body weight. The supplement, with 14% crude protein and 70% total digestible nutrients, was supplied for 30 days pre-mating, during the transition period from cultivated to natural pastures, consisting of 23 days on oats (Avena strigosa Schreb) and ryegrass...
Non-constituent carcass components of white and naturally colored Corriedale la...
Costa, Pablo Tavares; Vaz, Ricardo Zambarda; Esteves, Roger Marlon Gomes; Pereira, Yasmin Mendes; Mendonça, Gilson deThe study was carried out with the aim to verify the influence of the phenotype on the non-constituent components of the carcass of Corriedale lambs white and natural colored. The 29 lambs were used castrated males, from simple birth, from two phenotypes (13 natural colored and 16 whites), created in the Pampa Biome region, in Rio Grande do Sul State, in extensive system under natural pasture improved with ryeg...
Pregnancy at slaughtered in culling bovine females
Conceição, Viviane Garcia Dias da; Bethancourt-Garcia, Javier Alexander; Sartori, Dayana Bernardi Sarzi; Santos, Isadora dos; Silva, Hítalo Rodrigues daThe increase in the slaughter of females is cyclical in the Brazilian herd, normally influenced by a crisis in the sector, generating a reduction in herds. The slaughter of pregnant females at an advanced stage for a long time was prohibited, for sanitary reasons and for the maintenance of herds. The objective of this study was to characterize and quantify the slaughter of a slaughterhouse in the southern regio...
Profile consumption of sheep meat front to animal welfare in the view of produc...
Moraes, Renata Espíndola de; Soares, Mauricio Fornalski; Vaz, Ricardo Zambarda; Pereira, Giselda Maria; Mascarenhas, Mabel WiegandThe objective of this study was to investigate sheep meat: consumption habits, knowledge of producers and consumers about aspects related to animal welfare and the acceptance of certified products. 417 potential sheep meat consumers were interviewed using questionnaires. The interviewees were selected during the 92 Expo Feira de Pelotas and at strategic points of sale of meat such as: butchers, meat boutiques a...
Body size in beef cows and its influence on calf production
Vara, Carina Crizel da; Silveira, Magali Floriano da; Vaz, Ricardo Zambarda; Restle, João; Machado, Diego Soares; Macari, StefaniCattle farming becomes more intensive when the productive efficiency of the cows is increased, and nutrition is adjusted to the animal biotype. Eighty purebred Charolais and Nellore cows and their crosses between 3 and 7 years of age, were grouped for body weight at calving into Light (332.6 kg), Moderate (385.3 kg) and Heavy (444.6 kg). Cows and their calves were weighed at calving, at 63 days (early weaning) ...
Different corporal structures determining the effective production of Red Angus...
Castilho, Eduardo Madeira; Vaz, Ricardo Zambarda; Costa, Pablo Tavares; Fernandes, Tiago Albandes; Farias, Gustavo Duarte; Boligon, Arione AugustiThe objective was to evaluate the production and efficiency of 24-month-old Red Angus primiparous cows of different weights at weaning and repetition of pregnancy. Before calving, the females were managed in natural prairies and fed sweet clover (Lotus corniculatus) and ryegrass (Lolium multiflorum Lam.), with loads of 315 and 501 kg ha-1, respectively. Females were divided into groups according to the average ...
Biological efficiency of Charolais beef cows of different body sizes
Farias, Gustavo Duarte; Cerdótes, Liliane; Vaz, Ricardo Zambarda; Restle, João; Bitencourt, Marcia Ferreira; Alves Filho, Dari CelestinoThis study aimed to evaluate the production, reproductive performance, and productive efficiency of predominantly Charolais cows and their calves (Straightbred, ¾ C, ¼ N) according to body size at calving. Sixty-three cow-calf pairs were used and classified into three weight groups: Light (331.3±5.8 kg), Moderate (385.9±5.3 kg), and Heavy (424.4±6.2 kg). The classes were formed using half standard deviations ab...
Body size and its effects on productive efficiency of cows with predominant Nel...
Farias, Gustavo Duarte; Cerdótes, Liliane; Restle, João; Pascoal, Leonir Luiz; Costa, Pablo Tavares; Ferreira, Otoniel Geter Lauz; Vaz, Ricardo ZambardaThis study was developed to evaluate productive efficiency during the lactation period of cows with predominant Nellore genetic composition based on their body size. Cows were divided into the following categories: light (≤ 316 kg), moderate (≥ 317 and ≤ 400 kg), or heavy (≥ 401 kg). Body weight change and total gain from birth to 210 days of age of calves born from heavy cows (0.155±0.03 and 111.6±5.1 kg) wer...
