Abstract The objective of this work was to evaluate the effect interaction between feeding level (FL) and body condition score (BCS) on reproductive parameters Pelibuey hair sheep (Ovis aries). experimental units (64 ewes) were randomly assigned one four treatments: low score; high score. significant pregnancy lambing rates. ovulation, estrus returning, pregnancy, prolificacy BCS FL lambing, function is more sensitive better nutrition effects in with a
Abstract Adding gelling agents to convert the liquid state of semen extender a solid allows for an increased sperm life span. Gelatin and alginate have been used study effects on quality. However, there are other that not studied, such as agar. In addition, studying different sources or effect mixing more than one agent with extenders fertility has received little attention. Therefore, objective this was evaluate adding agar mixture from ram traits fertility. The first trial evaluated...
reproductive capacity of hair rams in the American Tropics. Design/ Methodology/ Approach: Scientific databases as Web Science, PubmEd, Scopus, Redalyc, Scholar Google, Dialnet, SciELO and Latindex containing scientific information were reviewed analyzed to describe nutrition, libido semen characteristics rams. Results: nutrition has been reported affect sperm production, libido, testosterone, testicular development. Rams start puberty at varying age, therefore with different weight, scrotal...
E Objective: the objective of study was to identify whether there is a relationship between environmental conditions high temperature and humidity with parameters cheese yield shelf life Oaxaca-type cheese, made throughout two different times year, delimited by temperature, in Mexicali Valley, Baja California, Mexico. Design/ Methodology/ Approach: from January November, ambient relative humidity, characteristics milk used at time reception (temperature, acidity, density, somatic cell count...
Background: heat stress diminishes semen quality in rams. Objective: to evaluate productive and reproductive responses of rams ram lambs with different rectal temperatures under conditions. Methods: the animals (n=12, Dorper × Katadhin Pelibuey crossbreed, 235 730 days old ) were assigned one three experimental groups: low temperature (RLLRT), high (RLHRT) Rams. Results: afternoon higher (p≤0.05) RLHRT group, there was no difference (p>0.05) between Rams groups. The ejaculated volume...
The hypothesis was that the level of sexual experience and reproductive status ewes affect time rams dedicate to courtship. Ewes (n = 40) were separated into four groups according their status: maiden, empty, under continuous restricted suckling ewes. Rams 8) experience: experienced-I -II inexperienced-I -II. Each group exposed at same a different 10-12 h intervals for 22 days, an injection prostaglandin given end this period. response variables each spent courting during first days...
This study evaluated the effect of injecting vitamin C (VC) and E (VE) on size preovulatory follicle, volume corpus luteum, pregnancy rates in Holstein cows under heat stress conditions (temperature humidity index > 74). Sixty-two were randomly assigned to one four treatments: 1, control, n = 15: not supplemented with vitamins; 2, VCG, simultaneously injected i.v. 500 s.c. 2500 mg VC before after estrus; 3, VEG, received an i.m. injection 3000 IU VE 4, VCEG, 17: same way doses as treatments...
Objective: To review the metabolic and hormonal processes that regulate reproductive activity in dairy cattleduring postpartum anestrus period.Design/methodology/approach: Analysis of scientific documents systematization information relatedto physiology management cattle anestrus.Results: Postpartum is an event occurs naturally necessary for restoration homeostasisof cow’s body following calving. However, failure to reestablish this homeostasis actually increases itsduration negatively...
Objective: To share technical aspects with specialists in animal reproduction and producers that could help to improve the reproductive capacity of caprine livestock. Design/Methodology/Approach: Scientific evidence experience management goats are basis sustains information presented this article. Results: The goat is widely distributed Mexico; it a species seasonal activity, but easy manipulation hormonal natural means. Presently there large variety biotechnologies can be applied production...
Vitamins C and E have been supplemented separately to improve fertility in cattle. The objective of this study was evaluate the effect combined injections increased doses vitamins on reproductive parameters dairy Lactating Holstein cows (n= 44) were randomly assigned one three treatments: 1) Control: n= 15, not injected with vitamins; 2) VCE3: received a single intramuscular injection 3,000 IU vitamin before estrus multiple subcutaneous total dose mg after estrus; 3) VCE6: 14, treated as...
Ascorbic acid (vitamin C: VC) is an antioxidant that participates in the regulatory processes involved development of ovarian structures and fertility. However, supplementation VC to dairy cattle improve fertility has received little attention. reduced associated with high genetic merit for milk production heat stress, which also diminish blood concentrations, suggest a potentially beneficial role supplementation. The objectives this review are contribute current knowledge regarding...
Objective: To review information related with the reproductive physiology and management of white-tailed deer for specialists producers. Design/methodology/approach: The presented in this document relies on scientific papers experience gained white-tail production systems. Results: White-tailed is a species seasonal reproduction one most important hunting Mexico. Currently, all biotechnologies applied to small ruminants can be used deer. Limitations study/implications: Information regard...
Background: recombinant bovine somatotropin (rbST) is used in embryo donors to improve superovulatory response and quality. Objective: this study evaluated the effect of applying one versus two injections 500 mg rbST donor Holstein heifers on estrus incidence (IE), diameter largest preovulatory follicle (dLPF), superovulation (SR), yield, pregnancy rate recipient cows (PRR). Methods: superstimulation programs were conducted. Heifers assigned treatments: 1) rbST-I, n = 5: received injection...
Ten pigs (65.55 kg IBW) were used in a 42-d trial to evaluate the influence of partial replacement corn with pecan shelling by-product (PSB) on performance, carcass characteristics and visceral organ weights finishing pigs. Dietary treatments consisted corn-soybean meal-based diet containing 0 or 10% PSB, where PSB replaced 13% (as-fed basis) two-phase feeding program. There was not difference average daily feed intake, gain, efficiency between dietary both phases. Fecal score as measure...
Se utilizaron veinticuatro cabritos (Boer x Rojo de Kalahari) en dos pruebas días cada una para evaluar la influencia administración vitamina A y E sobre el porcentaje actividad eliminación radicales libres durante destete. La primera prueba consistió los siguientes tratamientos: 1) suplementación (VAE), o 2) placebo (PCB), ambos administrados al destete condiciones ambientales termoneutralidad caprinos []. En segunda prueba, tratamientos fueron siguientes: 3) sin (SDT), 4) con (DTT), fuera...
Los remanentes de la industria alimentos, tales como producción frituras, pueden ser utilizados insumos para alimentación animales. Sin embargo, el efecto incorporación frituras en dieta ovinos sobre aspectos productivos ha recibido poca atención. El objetivo del trabajo investigación fue evaluar a corderos pelo su comportamiento productivo. Las unidades experimentales (n=20) fueron asignadas manera aleatoria uno dos tratamientos: Frituras y Control. grupo alimentados por 99 días con una...
Desde hace tiempo se especula que las fases lunares influyen en el comportamiento reproductivo de los animales. Se realizó un estudio para esclarecer la influencia manifestación estro, gestación, incidencia partos y sexo cría vacas trópico seco mexicano. Los datos reproductivos 580 mestizas 2010 al 2021 organizaron según algunos eventos (manifestación parto crías) ocurridos (luna nueva, cuarto menguante, luna llena creciente). La redujo estros (p<0.05). frecuencia crías no fueron...
